Re: [EVDL] EVLN: GM boosts Bolt production> (after killing-off Sonic ice)

2019-01-23 Thread Tom Keenan via EV
The article mentions low sales for the Sonic as a reason for possible end of 
production of the Sonic. Oddly, the monthly and yearly sales numbers of both 
the Bolt and Sonic are relatively similar - less than 2,000 each most months, 
and less than 20,000 each for 2018.

If this is based on dealership interviews/meetings, then then perhaps the 
dealership answer was really (...since we make less money on servicing 
electrics) we don’t want to sell them. Thus, we pretend there is no demand.

Re: [EVDL] Nissan Leaf key: $300! Yikes

2018-10-13 Thread Tom Keenan via EV
I have a 2013 Leaf.  It has a charging door open button inside at the left of 
the steering wheel.  I normally use the ‘inside’ button when I get home and the 
EV is parked for the day.  
Occasionally, I forget to unlock the door before I get out, or if I happen to 
not plug it in until later in the evening. The remote button is useful (saves 
opening the car, pressing the inside button, locking the car again) but really 
is only a small convenience.  Especially if you get the plug from the EVSE rack 
only to find you’ve forgotten to unlock the charge port door. 
I like having the remote charging door unlock on the fob, even if I only use it 
once every few weeks.

Re: [EVDL] Advice on new battery pack

2018-06-21 Thread Tom Keenan via EV
I have an old Zivan Charger (1.2/2.2 kW switchable, 120v input) that was set up 
for a 54 cell lead acid pack.  Tops out around 2.45 volts per cell (132.5 
volts) if you would like to use it.  Can be reprogrammed by a shop in 
Sacramento if needed.  Located in the Bay Area.

It was used in an old conversion that was decommissioned about a year ago.  I 
have a number of parts from that vehicle (9” GE motor, ‘gas gauge’ converter, 
large breaker switch, vac pump, etc.) if anyone needs a part or two for a 
conversion.

Re: [EVDL] Ford's Energi pih abandonment raises questions> (AK writer's EV-ignorance dogmatized)

2017-11-15 Thread Tom Keenan via EV
Way OT here, but months ago we drove a rental truck across country.  It was an 
E85 flex-fuel rig.  We stopped someplace in Corn Country and filled up on 
‘cheap fuel’ (E85) instead of regular E10 because it happened to be available. 
Instead of getting 10-11 mpg as averaged for the first part of the trip using 
E10, the mileage dropped to 6-7 mpg - a drop of about 25% in mpg over a 
relatively flat section of interstate. Came back up to 11 mpg or so once we 
filled back up with E10 at the next fill up (which came quickly after fewer 
miles per tank using E85).
This reflects very well the known difference in energy content between ethanol 
and gasoline.  Never bought E85 again, as it was very slow to accelerate the 
moving truck to freeway speed using that fuel, and zero advantage in cost/mile. 
At the prices mentioned below ($2.45/$3.01), the energy content is almost 
exactly the same per $ for E85 and E10 (‘regular gas’). In other words, as we 
found out during our real-world example, if you were to place either in your 
flex-fuel vehicle, they would have virtually the same cost-per-mile. So, one is 
not ‘way cheaper than the other’ when considering actual miles per $.  
Performance wise, I’d consider E85 inferior to E10 based on around 250 miles of 
suffering with it, and wondering why the gas needle was dropping so quickly.

I have a BC20 with the full set of resistors, and a Zivan NG3 that are used, 
and either should work well for your needs. Before that, you should check for 
ground faults. Spilled acid is one of the main reasons for increasing nuisance 
trips of the built-in GFI. Could just need to rinse off the pack.

Re: [EVDL] Leaf battery pack overheating due

2017-06-24 Thread Tom Keenan via EV
6 bars doesn't sound bad - 80 degrees or so  ambient will give you 6 bars. 
Here's a story on Reddit about a long trip in a Leaf - this guy definitely had 
a hot battery- at 11 bars.

Re: [EVDL] Complacent Leaf execs talk 200mi range in 2yrs

2017-05-09 Thread Tom Keenan via EV
Although the title is based on a dated article (2016) the longer-range 
redesigned 2018 model year Leaf is due out later is year. It does seem that 
they have been resting on their laurels a bit long. 
Looks like they are dumping current model year inventory ahead of the new 
version. At least one dealership around here (Bay Area) is offering $39/mo 
leases. That deal requires $3,500 down, plus a $13,500 Nissan rebate - so 
simply driving the lease off the lot lowers the potential used resale by 
$17,000.

Re: [EVDL] spray on PC board protectant

2017-05-08 Thread Tom Keenan via EV
The MiniBMS bypass resistor is a 5w/4.7ohm power resistor (cement type with 
axial leads). SMD (surface mount device) was probably meant to describe the 
other devices on the board.   The large resistor on the MiniBMS (the version 
I've worked with only has one) gets hot in use, so spraying a coating on it is 
probably not a good idea.

[EVDL] Sustainable Aviation and the Pipistrel Alpha Electro Trainers

2017-03-25 Thread Tom Keenan via EV
In case you are interested in electric aircraft, there will be a seminar in San 
Carlos on Saturday April 8th. I'm not sure, but this will probably just be a 
classroom presentation. 

Tom Keenan

"Sustainable Aviation and the Pipistrel Alpha Electro Trainers"
Topic: Safe, green, quiet and economical
On Saturday, April 8, 2017 at 12:00 Pacific Daylight Time
Location:
San Carlos Flight Center
655 Skyway Rd,
Suite 215
San Carlos, CA 94070
Select Number:
WP1575080

Description:

 

Joseph Oldham will present the Sustainable Aviation Project; the first 
deployment of production electric aircraft in commercial flight training 
service in the United States.  A joint effort between the City of Reedley, City 
of Mendota, Reedley College, Mazzei Flying Service, the Fresno Business 
Council, and the CALSTART San Joaquin Valley Clean Transportation Center, the 
project is using $1,071,348 in funding from the Fresno Council of Governments 
New Technology Reserve Fund Grant program for equipment, electric aircraft 
charger installation, technical assistance, and low-income student assistance 
costs.  Mr. Oldham will discuss the origin, development, and stakeholder 
engagement process for the project and provide updates on the current status of 
deployment of the aircraft and network of chargers to support their operation 
at four (4) airports in Fresno County.  The project benefits include:

Zero emission operations.

90% reduction in noise levels

Increased safety due to no flammable fuel on board for both pilots and ground 
personnel

Improved access to aviation careers through lower cost for flight training

Increased utilization and revitalization of rural airports

The Sustainable Aviation Project is designed to provide an essential first step 
for gaining public acceptance of the advanced electric aircraft technology 
being developed by entrepreneurs around the world.


 

Joseph Oldham, Director of the San Joaquin Valley Clean Transportation Center.

A native of the San Joaquin Valley and a private pilot since 1974, Mr. Oldham 
has had a passion for aviation since early childhood.  A graduate of California 
State University, Fresno, Mr. Oldham has spent most of his professional life 
working to improve air quality in the region through deployment of clean energy 
and clean vehicle technology.  

When the opportunity to develop a plan to deploy production electric aircraft 
for the first time in the United States in a practical way to support lower 
cost flight training operations, Mr. Oldham seized the chance, developed the 
plan, and helped organize an amazing team of people from local government, 
business, and education to make the plan a reality, and wrote the successful 
grant proposal that secured the funding for the project.

The Sustainable Aviation Project is not just the vision of one person; it is a 
vision of a region designed to change the way outsiders view the San Joaquin 
Valley and open doors for veterans and youth from the area to enter into an 
aviation career.   The project also will begin the process of getting the 
public familiar and comfortable with electric propulsion in aircraft as a step 
toward the advanced electric powered aerial sky taxi vehicles of the future and 
larger commercial electrically powered aircraft.

Mr. Oldham lives in Fresno, CA, with his wife Donna and two adult children.  He 
is co-owner of a 2007 Aeroprakt A-22 light sport aircraft and is working on 
getting his Sport Pilot CFI rating to be able to assist with flight training in 
the Pipistrel Alpha Electro aircraft when they are operational sometime in late 
2017.

Re: [EVDL] MAXIMUM VOLTAGE: Curtis 1238-6501

2017-02-20 Thread Tom Keenan via EV
The 1238-6501 uses 48 to 80 volts DC (nominal). The voltage of the pack will 
likely be a bit higher than the nominal rating. 
As an example, a 48 volt (nominal) lead acid pack might have a fully charged 
resting voltage around 52.5 volts, and similar 72 volt pack would have a 
resting voltage just under 80 volts. If someone made up an 80 volt pack, the 
resting voltage would be about 88 volts or so. 

That being said, what is more important is the highest voltage expected on the 
system. This will happen when the battery pack is being charged. The maximum 
voltage on a 72 volt pack while finishing a charge is about 92 to 96 volts, or 
about 100 to 104 volts on an 80 volt lead acid system. These are approximate 
numbers. (finishing/equalizing voltage varies by battery manufacturer, and 
occasionally by charger programming facility). 

The highest potential charging voltage for an 80 volt nominal system is close 
to the 108 volt number you have - I would consider that to be an absolute 
maximum voltage that is encountered on rare occasions.

Anything higher than an '80 volt' pack risks popping this controller. Staying 
with 72 volts max (nominal) will give you a good safety margin and longer 
controller life.

Re: [EVDL] HPGC AC-31-01 Diagram or Manual

2017-01-29 Thread Tom Keenan via EV
I also have an older DC powered conversion with a clutch. I've found that 
shifting with the clutch is much faster and much more forgiving.  I've driven 
it 'clutchless' a couple of times as an exercise, but found it to be very slow 
to shift with the foot off the clutch.  Matching motor speed with selected gear 
normally results in time wasted between gears waiting for the motor to wind 
down - traffic behind becomes very intolerant if you miss the split second 
between go and no-go. 
Tougher on hills because the vehicle may slow down to almost nothing before the 
motor winds down enough to shift clutchless. Then you are back to square one 
(first gear again).
However, since AC motors have a much wider RPM operating range, frequent 
shifting isn't really necessary as with most DC motor conversions. 
One conversion I've seen with an AC motor was a clutchless Geo Metro 
(Solectria). The AC motor twisted off the transmission input shaft in that 
particular vehicle twice, requiring a transmission replacement both times. 
Might be a poorly matched transmission design, or it might be that the clutch 
provides a bit of overtorque protection. 
Based on what I've seen and operated for the last few years, I'd recommend 
retaining the clutch.  If you have a clutch-type conversion of any type 
available to test drive in your area, try to drive it both ways to see what 
fits your driving style before you commit.

Re: [EVDL] Shorted FB1-4001A DC motor?

2016-12-27 Thread Tom Keenan via EV
I have a similarly sized GE motor, and it takes about 30 amps to run with no 
load. However, it overheats my 30 amp power supply if used for too long, and 
the motor needs about 50 amps to start turning.  You can start them
with a 12v battery in parallel with the power supply for a few seconds if the 
PS won't start it on its own. 
One older EV I had failed due to a commutator crossover link short to the motor 
case inside the motor.   Made a lot of copper snot when it violently melted at 
about 40 mph. But ultimately repairable
for relatively cheap. 
You should not have a low resistance reading between the case and any field or 
comm winding terminals; if so it might indicate a problem. Higher resistance 
usually indicates carbon dust inside the motor, and open rarely is seen on a 
well used DC motor. Low resistance between field terminals, or between winding 
terminals is OK (in general - but doesn't rule out a short). 
My present EV blew a fuse once due to water getting into the charger after a 
hard rain (a real oddball). 
One other item to check - There is the possibility that one of your HV cables 
has rubbed through the insulation, and is shorting to another HV cable or the 
vehicle frame someplace.

Re: [EVDL] Electronics help anyone

2016-10-26 Thread Tom Keenan via EV
I ended up replacing the bi-metal 'voltage regulator' with a solid state 7805 
(if memory serves) to provide voltage to the fuel gauge and the temperature 
gauge (I use an OEM temp sending unit attached to the motor case). Works fine 
with the ZEVA unit on the '89 style gauges.

I have a similar device in my old Electron Ford Escort - a ZEVA fuel gauge 
driver plus. It works quite well with the old Ford analog gauges. 
http://www.evwest.com/catalog/product_info.php?products_id=144
You might try their setup file - might be the same device as the one you have, 
just made in Australia.

Re: [EVDL] New EV world record set

Yep - setting an EV record in a Mirai is kind of like saying they broke the 
'all electric' mileage record with a Volt or Prius Plug in. Just has a 
different type of generator on board. Probably why the tease line and the 
cryptic URL without referencing that it was really a fuel cell advertisement -

Re: [EVDL] EVLN: Na Researchers reveal 650mi on single-charge Tesla 'superbatteries'

It would billed by kWh (amount of energy delivered). There would likely be an 
increased cost for fast charging (higher power charging = more kW) because fast 
charging may be more convenient in some situations. But ultimately the final 
cost would depend on amount delivered.

Re: [EVDL] Used EV's for sale on Autotrader

2016-08-21 Thread Tom Keenan via EV
A big part of the increased availability of used EVs is that most electrics 
(according to an October 2015 CNBC article, around 80% in 2013 and 2014, 
currently around 75%) are leased as opposed to sold outright. This compares 
with about 28% of ICE vehicles being leased.  As these three-year leases end, 
they are either auctioned off or sold by the dealership they were returned to. 
I haven't seen any data yet on the 'loyalty' rate of lease returnees either 
getting another EV or getting oil regressing back to fossil fuel.

If it works as advertised, it might save some weight in reduced coolant volume

Re: [EVDL] VW is claiming new EVs will use 48-volt systems

2016-02-06 Thread Tom Keenan via EV
48 volts does indeed seem low for a modern EV, particularly one that weighs 
more than 3,000 pounds and is expected to go more than 60 MPH.  
I had a 48vdc (nominal) Citicar (about 1350 pounds empty) a few years back. It 
would struggle to go over 35 MPH. With a 450 amp controller, there is about 29 
HP available.  For reference, a 1967 Beetle (about 1,800 pounds empty) had 
about twice the power available (53 hp), and they weren't exactly known for 
their acceleration or high speed prowess. 
Typical lithium cells have about a 3C discharge rate; 450 amps continuous would 
require 150Ah cells. Any discharge greater than 450 amps (in this 48v scenario) 
would need higher capacity cells, and physically larger cables and contactors.  
To increase power, it is easier and less expensive to increase voltage, rather 
than amperage. 
Based on the same physics, it would appear that any 48v system would only be 
useful as a parallel augmentation system in a hybrid vehicle, and not as a 
primary propulsion system in a vehicle intended for use on a modern freeway.  
My guess is that VW plans might include using  a 48v battery linked to a higher 
voltage inverter driving a 120v or so AC motor.  Even so, the stress on a 48v 
pack  feeding this sort of system would be significant. 
Using a 48v pack might have a legal precedent, aimed at keeping some 
regulations or specific legislation at bay, as 48v is not considered high 
voltage.

Re: [EVDL] Question: L5-30P vs L6-30P

2016-01-17 Thread Tom Keenan via EV
If you look at the linked chart, the main difference is that the hot and 
neutral (two hots on the L6-30) are reversed, as far as width goes.  Because of 
the switched widths, they won't plug into the other voltage receptacle.

It's also possible that the Bolt test drivers were a bit heavy footed to see 
how it would perform.  That, and any car needs to have the driver 'broken in'

Re: [EVDL] Repairs Needed

2015-12-10 Thread Tom Keenan via EV
I've made an open EVSE as well.  They work great.  Just make sure you get a 
main relay of sufficient capacity, as the first one I built only had a 20 amp / 
240v (4.8 kW) max.  Installing a 30 amp version takes the same amount of time 
and physical space, and only costs a few dollars more.

Hi Bruce,
Thanks for going through all the articles and posting the best.  I do a similar 
function for my 'day job', so my appreciation for what you do is that much 
greater.

My daughter likes the combination of a Verizon iPhone and a tethered iPad for 
connectivity.  I have ATT, and the connectivity isn't as good much of the time. 
 Not sure if either system is what you're looking for. 

Have a great week!

Re: [EVDL] UK grid too weak for 34M EVs (not when we stop pumping gas too!)

2015-12-05 Thread Tom Keenan via EV
Yep - the old 'fat fingers' on the bitty keyboard.  The owner said he normally 
gets 200 to 400 cars per day - it is a busy station.  So, instead of 125 to 175 
Wh per car share of the gas station power use, it works out higher, to 1.25 - 
1.75 kWh per customer.  Five to seven EV miles could be driven on just the 
electricity used by this gas station/store per ICE gasoline tank fill as a 
rough estimate. 

As fas as convenience stores that are primarily gas stations (the customers go 
there to get gas, but also buy chips, soda, coffee, etc. because it is a handy 
impulse buy) are different than convenience stores that also sell gas 
(customers go primarily to get milk, newspapers, lotto, beer, cigarettes, and 
occasionally get gas, if they have the time and need).  

The price or handy accessibility of gasoline attracts some customers to the 
convenience store at the first sort, and the ready availability of staple items 
attracts some people to the gas pumps at the second, but gasoline is not the 
prime attractant.  These secondary stores generally don't have very many gas 
dispensers; oftentimes only two vehicles can fill simultaneously. Gasoline is a 
significant part of business in the first model, and the associated convenience 
store would probably fold if they had no customers stopping by to get gas.  If 
gasoline sales fell off at the second sort, the associated store would likely 
continue in business, at least for a while.

Re: [EVDL] UK grid too weak for 34M EVs (not when we stop pumping gas too!)

2015-12-05 Thread Tom Keenan via EV
About two years ago, I asked a gas station/convenience store owner what the 
normal amounts of electricity they used were, and he said about 350 kWh in 
summer, and 250 kWh in the winter. (Natural gas heating). I asked if this was 
for an entire month, and me said no, that was the amount used for a single day! 
 He showed his power bill as proof.  I was quite surprised, as my house uses 
roughly that amount per month. 

Granted, most of the energy was used for beverage and food coolers (about a 
dozen) and air conditioning. He estimated that the eight gasoline and two 
diesel dispensers and lift pumps was about a quarter of the total energy use 
for his station. 

If one considers this a typical store/gas station, and it serves perhaps 2,000 
vehicles a day, each vehicle's share of energy is between 125 and 175 Watt-hours
(0.125 to 0.175 kWh) when they fuel up.  This takes into account their 'use' of 
powering the store, whether they buy soda and cigarettes or not. 

Obviously, energy used at a gas station is only a small part of the equation- 
extraction, transport, and refining of crude oil use vastly more amounts of 
energy in the whole petroleum cycle.  The total energy used per vehicle would 
need to include that power used as well. 

Thought of another way, if the station were to go away (due to customer 
attrition)  there would be an additional 250 to 350 kWh available per day for 
the grid to power plug-in vehicles.  At 250 Wh/mi, that would translate to 
1,000 to 1,400 miles per day of electric driving. Or enough miles/power to 
satisfy about 25 to 35 EVs doing forty-mile (round trip) commutes.   The gas 
station attrition model would appear to need to eliminate about 2,000 ICE 
vehicles to shut down one gas station.

 We were trying to get Elon Musk, but I think he's scared of me, said

Re: [EVDL] Last call for LeSled

2015-06-14 Thread Tom Keenan via EV
I can understand the lack of potential conversion buyers.  My present EV, a 
1989 Ford Escort converted by a company in Santa Rosa, was on sale at one point 
for $2,000 but it never sold. Ultimately, the owner put it up for grabs on the 
local EAA list.  I put a set of new lead acid batteries in, and it has been 
relatively trouble free for the past three years.  It has had its share of 
mechanical problems, but it is a 1989 Ford Escort at heart.

The big quandary for my EV will come in a year or so when it needs another 
battery pack.  Does one spend over $8,000 to upgrade to a marginal lithium 
pack, charger, and BMS, or $2,500 on a lead acid pack that will work, but with 
the lackluster performance it has always had just to drive it a few thousand 
miles for the next few years?

Putting $8,000 into a battery pack for an old, and otherwise unremarkable car 
would seem to be the height of folly, particularly when modern but used, 
factory made EVs (Leaf, iMiEV) can be had for just a bit more.

Re: [EVDL] Easy EV Comparison - The Enemy is Us?

2015-06-07 Thread Tom Keenan via EV
 It'll mostly be an all-electric vehicle -- to the point that, as with Volt 
 owners, save for road trips, I'll have to pay attention to not letting the 
 gasoline get stale in the tank.

In speaking with Volt manufacturer reps, they say that the Volt engineers 
thought of that as well.  They programmed the vehicle to turn on the engine 
(while driving - may take several trips if they are short) and use a good 
portion of the fuel if it detects that it hasn't been fueled in a year.  

Apparently, even the most conscientious Volt owner will have to go to the gas 
station and fill up every once in a while.

Re: [EVDL] Comuta-Car PbSO4 batteries

2015-05-30 Thread Tom Keenan via EV
Another thing to consider when getting batteries is the overall height, 
including terminal posts.  There isn't much room height-wise in the bumpers 
where the batteries are located. Will the 8v batteries have the same physical 
dimension as the T-105?  The batteries nearest the ends of the Comutacar will 
have less of a problem, but the inboard batteries have a metal frame right 
above some of the terminals.
Changing from eight 6v to six 8v batteries to keep 48v may create too much room 
in the battery boxes, as they were designed to be more or less crammed in place 
and held down with a single bolt in the center of the four batteries, with the 
edges of the box keeping the square arrangement in line.
The charger in stock Comutacars is somewhat underpowered because there is 
another charging system for the 12v system battery that lives under the 
driver's seat.  If memory serves, the 48v charger puts out about 20 amps (~1kW) 
compared to the Lester chargers in older Citicars that put out about 25 amps 
(~1.2 kW). Both use about 14-15 amps from the wall plug, and the chargers are 
very sensitive to input voltage. If a normal 120 - 125 volts is present at the 
plug when charging, they would charge relatively quickly.  If the wiring wasn't 
up to spec, or the pole transformer was set low, (perhaps 110 to 115 volts) 
they would take forever to finish a charge, and would probably not get a good 
finish charge because they ended below 60 volts.
If the new buyer goes down to 36 volts (6 6v batteries) they will need a 
different charger, and the top speed will be reduced significantly, from about 
35 mph for 48v to 28 mph at 36 volts.

Re: [EVDL] Damaged ADC FB1-4001A Motor

2015-03-04 Thread Tom Keenan via EV
It sounds to me like an overspeed. One or more of the individual commutator 
segments has broken free of the bonding. Although it may be possible to rewind 
the motor, a replacement may be the less expensive/most reliable route. 
If only the commutator is damaged (one or two bars lifted under the brushes) 
you may be able to get by with turning the commutator and strengthening with 
Kevlar tape. Best to check with a competent and local motor shop.

 3) What kind of parts and costs are likely involved?
 4) Can this be a DIY project for a handy person?

They generally tow cars away for free if the scrap metal is worth at least the

 I had checked into the VA Hospital yesterday morning, and my big/large mouth
 had no problem taking in the breathing tube down my windpipe which my
 anesthesiologist was quite concerned about after seeing on the CAT scan that
 my left side thyroid goiter (growth) was pushing on my wind pipe, narrowing
 it and pushing it to the side (I did not notice any of this as I was in no
 pain, but all the VA doctors were hot to yank the whole thyroid, but got
 them to back off a bit and only take the left side which was causing the
 issue).
 
 I am really glad I do not remember most of the beginning before they knocked
 me out. Though my memory isn't as sharp as when I was younger, I can still
 replay my life experiences a little too well (a good memory did have its
 upside, when I could remember/visualize in my mind my homework pages I had
 done the night before when taking a test that day - it let me be an A

 All in all, I awoke doing pretty well, with all the doctors and staff
 looking at me amazed at how large the goiter was (?). I had a large bandage

Re: [EVDL] How crazy am I?

2014-07-22 Thread Tom Keenan via EV
The discharge rate of the cells should play into the calculations as well. If 
the cells have a 3C max rate, 45 90 ah cells could produce about 52 HP (270 
amps max@144v), resulting in a somewhat underpowered vehicle.  
How much does exceeding the discharge rate reduce the life of the pack?  Is 
there a discharge rate that, once passed, makes the pack subject to random cell 
failures (i.e. more than 10C will damage the internal structure of a certain 
brand cell )?

 a couple dozen miles would be plenty. I suspect that the smallest pack

 right size ...
 
 Hmm.  Maybe.  Let's do some math.
 
 A typical subcompact conversion uses around 250 Wh/mi.  (Some have done as 
 well as 150-160 Wh/mi, carefully driven.)  You're not going to match that 
 with a heavier, less aerodynamic car that wasn't designed with fuel 
 efficiency in mind, however.
 
 What can you do?  Well, in the EV Photo Album I found a '66 Mustang 
 conversion that does 375 Wh/mi.
 
 http://www.evalbum.com/733
 
 Here's a '65 ragtop that does 330 Wh/mi.  That sounds a little better.
 
 http://www.evalbum.com/2056
 
 One other similar Mustang entry estimated his energy use as at most 500 
 Wh/mi, but we'll take that with a grain of salt that since he doesn't seem 
 to have measured it accurately yet.
 
 Now, these are BEV conversions.  You're leaving in all the ICE bits for a 
 car that will probably weigh in the 2800-3000lb range before conversion, 
 maybe 3500 or more after.  You'll might also pass up the skinny LRR tires 
 for sticky high performance ones.  So let's be conservative (and assume you 
 probably won't drive like I do ;-) and allow 400 Wh/mi.
 
 You want about 25 miles of range.  So you need 10 kWh, but you don't want to 
 size your battery to that.  You probably want to not exceed 80% DOD for good 
 life, but let's say you're OK with giving up a little battery life, and go 
 to 90%.  So you actually need a battery capacity of about 11.1kWh.
 
 Doing that with lead in the space you have is going to be a non-starter, so 
 I guess we'll go right to lithium.  A LiFePO4 cell has a nominal voltage of 
 3.2v.  Let's say you're going to use a 144v drive system, so you'll need 45 
 cells.  (In a more reasonable world, you'd determine how much energy and 
 power you need, and size the battery from that.  THEN you'd decide what 
 motor and controlller would work with that battery.  However, we'll assume 
 for now that you've already chosen a motor and controller, because it makes 
 the calculations easier.)
 
 We'll start with, as you suggest, the smallest pack that puts out the 
 necessary voltage.   The laptop-size cells are obvously too small unless 
 you go to massive paralleling a la Tesla, so let's jump to something like 
 Headway 38140 cells. I'm no lithium expert, but I'd guess that these are 
 about the smallest lithium cells practical for an EV (and a pretty light one 
 at that). 
 
 The 38140s are 12ah cells, 38mm in diameter and 152mm long.  Because they're 
 cylindrical, packaging isn't optimum, but (allowing a little wiggle room) a 
 5x9 matrix would be 152mm (6) high, 200mm (7.9) wide, and 360mm (14.2) 
 long.  Your battery box will need to be at least 25-50mm (1-2) larger in 
 all dimensions than this, to allow for wiring, ventilation, and (in the 
 winter) insulation.  So you're looking at maybe 8h x 10w x 16l.  I don't 
 know how that compares to a banker's box, not being familiar with such a 
 critter.
 
 Each cell is good for about 38.4 Wh, so 45 of them would be ... 1.73kWh.  
 Hmm. That would get you about 4.3 miles of range.  We're going to need 
 something larger.  
 
 How about CALB?  The smallest one EVSource sells (that's not an endorsement, 
 it's just one place I found offering them online) is 40ah.  
 
 Each cell is 181mm x 115mm x 46mm.  Again allowing a couple mm per cell for 
 breathing room between (the lithium experts here can give you more info on 
 whether this is necessary), your battery is now 181mm (7.1) high x 585mm 
 (23) long x 432mm (17) wide.  Again add at least 25-50mm (1-2) to each 
 dimension to allow for battery box sizing, to get to around 9h x 25l by 
 19w, maybe even a little higher to allow for installing a BMS.
 
 Now with 45 cells we're talking 5.8kWh and a practical range of 13 miles 
 with new cells, declining to perhaps 9.8 miles after a few years of use.  
 Still only about half what you want.  (But can you live with it?)
 
 Let's see what we can do to get closer to your target range.  The Winston WB-
 LYP90AHA is a 90ah cell.  This will give you nearly 13kWh for a practical 
 range of 29 miles, perhaps 22 miles as they age.  Now we're talking.
 
 Each cell is 218mm high x 143mm long x 61mm wide.

 Update and EV grin.  I took the VW bug out for the first serious drive
 with Lithium last night.  WOW.
 
 Before -- with the 12 volt AGMs.  I was getting maybe 280 amps peak battery
 amperage on a freshly charged pack, dropping to less than 100 amps after 5
 miles or so.  Pathetic performance (lots of driving on the shoulder).
 
 With the 100AH, 72 volts of CALB lithium, I was regularly getting 200 amps
 on acceleration, and I got 370 amps peak once (should probably not do that
 too much for the health of the batteries).  The alltrax 450 never even got
 warm, with it's new heat sink and cooling fan. It's peppy now... way more
 than a ICE VW bug.  30mph up hill, and can pull out onto the highway just
 fine (highway being the 45mph road -- not 75mph freeway).  And... the motor
 (6.7 series) is actually running cooler than before as well.  I think
 because the controller is able to keep the speed up, the motor RPM is not
 dropping like it was before, so it's actually cooling better with its
 internal fan.  And, it takes less time to climb the hill when you can keep
 up 30mph instead of 15.  After climbing a two mile hill at 250+ battery
 amps most the way, it was hot but not too hot to hold onto.  I kept it in
 2nd up to about 40, then switched to 3rd for more power on the highway.
 1st is able to peel out in the dirt.  I'm sure that driving it like that
 doesn't help the efficiency, but it's way more fun that it was as a lead
 sled (it's also about 400lbs lighter).  One thing 50mph around curves
 is a little scary... something to do with standard suspension and brakes of
 a '73 VW bugI only took 20AH out of them, because I don't have the
 BMS connected to the controller yet, but this weekend, I'll do a full range
 test with the BMS operating.
 
 Makes me want to get lithium for my Ford conversion.
