Re: [EVDL] Chevy Bolt Level3 fast charging time

[Bill Collins via EV]

To answer the question about how Texas power companies can charge so much 
legally: Texas operates its own power grid so it can be exempt from federal 
regulation. State regulation is minimal, in line with the "every man for 
himself" attitude common there.

That seems to be a dealer reposting cars from copart. Their broker fees are 
more reasonable than some, so they will be a good resource for cars that 
require a dealer license. Thanks!

[EVDL] Smart ED Parts

[Bill Collins via EV]

Does anyone know of someone parting out a 2013-2015 Smart ED, selling a wrecked 
one, or a salvage yard that knows EVs? I'm in North Carolina. The part I need 
should be easily shipped, or I can travel to nearby states to pick up a parts 
car. I've been searching copart auctions, but haven't found anything yet in a 
reasonable distance that I can buy without a dealer's licence.

I need the onboard charger for my 2013. The new part from Mercedes costs over 
$4k and the part is not listed in the database salvage yards use. To further 
complicate things, LKQ Salvage doesn't even have Smart in their database!

Re: [EVDL] buying used Leaf BMS

[Bill Collins via EV]

Check out plugshare.com, or the plugshare mobile app for locations of chargers. 
If you buy a LEAF with the DC fast charge connector, and if there is a fast 
charge station on the way, you won't have to charge long.
There is a Seattle area LEAF owner's group on Facebook that is very helpful. 
I'm sure people there will be familiar with the route you need to take.

Re: [EVDL] Smart ED charging issue

[Bill Collins via EV]

Part of the problem with the Smart ED is that most of the service information 
is contained in the Mercedes STAR scan tool and not available as a shop manual. 
I will see if I can locate a reset.

Parts for these are very rare in salvage yards. A semi-local used car dealer 
has one that won't charge that they have been trying to sell for nine months 
for $3000. I'm considering trying to talk them down significantly on the price 
and buying it for parts (or using my car to fix it), but first I need to verify 
that its charging fault is in the BMS as claimed and that mine is in the 
charger (or at least something other than the BMS).

Re: [EVDL] Smart ED charging issue

No problems are reported by the EVSE and I know the service disconnect is OK 
because I can drive the car.
I hadn't thought of the possibility of a blown fuse causing something like 
this. I will check them.

[EVDL] Smart ED charging issue

[Bill Collins via EV]

Does anyone here have any experience diagnosing the Smart ED? Here's what's 
going on with mine:



My 2013 Smart ED is no longer charging. When I plug it in to the EVSE, I hear 
the usual clicking of contactors in the car, the EVSE contactor closes and then 
opens again within a half second, and the dashboard flashes "Malfunction". This 
repeats as long as I have the EVSE connected. (Yes, I have tried three EVSEs, 
all of which used to work with the car)
I have tried to scan for error codes with an iCarsoft MBII and a Delphi DS150, 
but neither will scan the EV specific systems.

Any suggestions for a scan tool, or do I have to take it to a shop with a STAR 
tool? Anything I could check without a scan?

 

I have verified that there is no damage to the wires connecting the charge 
inlet to the charger module in the car.

Re: [EVDL] NICAD Batteries

I took a quick look at that before buying a few BB660 cells to experiment with 
as a starting battery for an ice. They seem to meet all the requirements for 
dropping off in the battery recycle bin at Lowes home centers. It's not a 
practical way to dispose of a large number, but for a few dead cells, I would 
just drop one off from time to time.

I'm interested in hearing the details on larger scale recycling too.

Re Silver Zinc batteries: I worked on a charging system for the U2 aircraft

As I recall, the cells were rated for 10 charge/discharge cycles and a calendar

Re: [EVDL] Smart ED battery

Here's what my local expert says:

"Go take a look at the Smart Club of America forums because this has been 
discussed and Mercedes Benz is not only turning off that program but they have 
no interest in going after the vehicles that came off lease. In fact the legal 
responsibility is on whoever bought the vehicle at auction they signed the 
paperwork and they're the ones that are on the hook for it, if it's changed 
hands at a couple dealerships you got nothing to worry about. I want to say 
yours the battery was bought out right because the guy who originally owned it 
lived in Sanford and that's why it's got such high mileage"

I will check out the forums when I have a chance.

No, it does not have a way to shut it off remotely. I suppose they could try to 
keep the car if I took it in for service, but I don't think they would have any 
legal grounds, since I have no contract with them.

I just bought the car like any other used car. So, either the previous owner

I will contact a friend who seems to know everything about the Smart ED and see

Re: [EVDL] Smart ED questions

[Bill Collins via EV]

It was towed to the dealer because of a fault in the motor control electronics. 
They replaced a module under warranty, but didn't give many details. When it 
threw the fault code, it would not move under its own power (I coasted into a 
parking lot). By the time AAA arrived, saw that they needed a rollback truck, 
and returned with the right truck, it would drive again, but I didn't trust it 
to make it to the dealer.
A friend had somewhat similar symptoms with his and had the accelerator pedal 
sensor replaced under warranty.

The car was running when I bought it. $4500 is a pretty typical price for a 
2013 in the Raleigh, NC area.

Re: [EVDL] Smart ED questions

[Bill Collins via EV]

I recently bought a 2013 Smart ED for $4500. I own the battery.
I took it to the Mercedes dealer (Leith, in Cary, NC) and they kept it for two 
weeks. The only loan car they could give us (after we asked, they did not offer 
it) was an ICE Smart, which is a horrible car to drive. 

The car itself has been fun. It's not as refined as the LEAF, but drives like a 
fast little go-cart! It feels like a really well done EV conversion, while the 
LEAF feels like it was designed to be electric.
The lack of a service manual bothers me, but there seems to be a growing body 
of DIY info, including a leafspy like device that's in the prototype stage and 
a $200 code reader that's claimed to work with the Smart electric. We also have 
an independent mechanic that is working with one of the local Smart EV owners 
to learn how to repair them.

[EVDL] Using the LEAF drivetrain in a conversion

[Bill Collins via EV]

Has anyone been able to talk to the LEAF inverter directly? I know it's 
possible to run the LEAF drivetrain outside the car if you take enough of the 
car with it, but It would be a lot easier if you could just send CAN commands 
directly to the inverter.

Re: [EVDL] Forklift Battery Options?

[Bill Collins via EV]

If you go with replacement batteries that are significantly lighter than the 
original, keep in mind that the batteries are part of the balance equation that 
determines how much weight can be safely lifted and how high it can be lifted. 
You either need to add ballast to increase the weight or be careful not to use 
the forklift near it's limits.

A friend has a small walk behind forklift that originally used two 12v deep 
cycle batteries about the size of a golf cart battery. Right now, it's running 
on a pair of gel cell batteries from a mobility scooter. We're careful not to 
lift too much weight with it.

Re: [EVDL] Ford Focus EV battery for conversion?

[Bill Collins via EV]

I really dislike the idea of high voltage BMS wires running all over the place.
My plan, if I use LEAF cells, is to make a PCB that attaches directly to the
battery terminals that has a microcontroller reading the cell voltages and
sending the data via an optically isolated serial bus that is daisy chained from
one cell to the next.

[EVDL] Ford Focus EV battery for conversion?

[Bill Collins via EV]

I've been planning on using one or more LEAF batteries in my conversion project.
In searching salvage yard listings (car-part.com), I'm seeing a lot of Ford
Focus EV batteries for similar prices to the LEAF, but they are generally newer
batteries.

Has anyone here used cells from a Focus? The built-in water cooling heat
exchangers seem like a good feature, and the fact that they are water cooled may
mean that the salvaged batteries may be in better shape than the LEAF ones.
(I've decided that if I go with a LEAF battery, it will either be very new or
come from a northern salvage yard)

Re: [EVDL] Electronics help anyone

[Bill Collins via EV]

The PCM probably had a resistor to a regulated voltage source, so that the tank
sender produced a varying voltage instead of just a resistance.

[Bill Collins via EV]

Most Jettas are front wheel drive. Do you already have one of the all wheel
drive ones? If not, you're looking for a rare car to convert.

Re: [EVDL] Current limiting

[Bill Collins via EV]

That would be an extremely short lived event. Once current starts to flow, delta
voltage will decrease rapidly.

Re: [EVDL] Current limiting

[Bill Collins via EV]

The resting voltage of a lead acid battery is significantly lower than the
voltage required to charge it. For example: a fully charged 12 volt battery has
a resting voltage of 12.6, but will not draw much current unless you apply 13.5
volts or so. This means that when you connect two batteries with different
states of charge, less current flows than many people think.
