Re: [EVDL] Charge to 100% after discharging to 0% for BMS equalization.

2024-01-14 Thread (-Phil-) via EV
Yeah, My procedure is to charge to 75% overnight normally, or higher if
needed.  3-4 times a year I need to take a road trip, so I charge to 90%
overnight, then 2 hours before I am about to leave, I'll take it to 100% to
give it time to balance.   (I have ternary/NMC not LFP)   The pack doesn't
sit too long at 100% when you hit the highway.

You really don't need to worry too much about balance unless you see a drop
in range, then do a balance, and if you get some range back after a week or
so, do it again and ad nauseum until you don't see any gain.   I think
doing it a few times a year does a pretty good job of keeping it in-check,
but all packs are different, so YMMV.

Thanks Phil for the informative reply.  I plugged in immediately when getting 
in the driveway and waited a couple hours before unloading, chain sawing and 
splitting the wood (with an electric Worx chain saw and Swisher electric log 
splitter).  
Last time I charged to 100% was at Cocoa Beach Florida in October.  Some EVers 
told me to just charge to 80% like I normally do and others say to charge to 
100% after a deep discharge- so I split the difference and charged to 90% :-)
Next time I’ll charge to 100% is when going to Gatlinburg, Oak Ridge Tn and 
Mammoth Cave Ky in February.

You do not need to do a balance charge often.  I'd say 3 to 4 times a year is 
sufficient, just do not let it sit at 100% after this charge. Plan to drive it 
soon after it finishes.  LFP is less susceptible to this kind of degradation,

Mark specifically said software, but if the orig poster meant Hardware, and 
that 
Tesla should sell models without the hardware for FSD, Enhanced Autopilot, Seat 
heating, Premium connectivity, etc, then I would think that would make the cars 
much more expensive. For example, instead of having one steering system that 
would 
accommodate all the Tesla variations and needs only to be OTA software updated 
to 
upgrade from one level to another, you'd have several distinctly different 
system. 
So you'd have different softwires, different hardwires, increased shipping and 
stocking cost, increased production costs for different builds etc. Sort of 
defeating the point of an affordable car.

I sort of think that my Tesla is like a swiss army knife, and we all know how 
popular they and their off shoots have become. I don't need the scissors until 
I 
need to cut something, so I just unfold them, use them and put them away when I 
don't need them, just like I do with the other blades. And the same is true 
with a 
Tesla, when I need the FSD, I pull down on the steering wheel lever, use it, 
otherwise is  invisible and not in any way a problem. If I want to use the map 
features of the center console, I just tap an icon and there it is, true I have 
to 
pay an extra $10 or so a month, but along with all the other enhances I get, it 
is 
well worth it.

[EVDL] EV Standards, was: Rental giant Hertz dumps EVs...

2024-01-14 Thread fred via EV
As a current owner of a non-working Gizmo EV, I can offer that the steering 
appeared to be daunting, but operated in the same manner as an ordinary 
motorcycle and required zero adaptation. I believe the handgrips on my 2003 
unit were fashioned from an F-16 but the buttons operated also in the typical 
motorcycle manner. Turn signals, wiper, horn. Having an accelerator trigger 
with a 5 mm travel meant one should be sensitive with the application of power, 
however.
People found the top hinged door amusing and far too often compared it to the 
Isetta, the steering to a skid-steer.
As an aside, if one wants to own one of the 36 manufactured, I'm open to 
offers. It does appear to be a candidate for Barn Finds, however.

He means not including the hardware.   All cars get the same hardware.
They can't do this because the other driver assistance features (Automatic
Emergency Braking, etc), are delivered by the same Autopilot ECU.  (Tesla
calls the APE)   Also included is the GPS receiver used for navigation, and
the rear camera used for the (now required) RV camera function.

To be clear:  Tesla's with "one pedal" mode (called "hold") uses regen
until low speeds where it's not enough, then uses the iBooster to apply
hydraulic brakes.   It fades in the hydraulic almost perfectly, and holds
the brakes firmly on even with no feet touching pedals until you press the
accelerator again.

For a Tesla? No idea, but my gut feeling is that when the

2024-01-14 Thread (-Phil-) via EV
You are fine, just don't let it sit at low SoC.   The "battery damage"
comes from the fact that Tesla's BMS on the 3/Y are somewhat parasitic, and
continue to suck power from a discharged pack.   There is added degradation
from time spent at low SoC, but not "damage".

You do not need to do a balance charge often.  I'd say 3 to 4 times a year
is sufficient, just do not let it sit at 100% after this charge. Plan to
drive it soon after it finishes.  LFP is less susceptible to this kind of
degradation, but it still happens.

Re: [EVDL] 156v Tech assistance needed

2024-01-14 Thread (-Phil-) via EV
The reason people use charge controllers is mainly to stop overcharge.
The secondary benefit with a controller that can do boost or buck is MPPT
(Maximum Power Point Tracking), so you can couple the PV to the battery
more effectively and waste less of the energy as heat.   If you hook ten
120W 12 volt panels (~ 10 amps each) in parallel with your 12 volt battery,
you would get (theoretically) 100 amps in.  If you hook those same panels
up in series, you would get 12 volts out at 10 amps.   The voltage stays at
12v when hooked to the battery, not the ~120v it would be open-circuit.
The ideal voltage the panels "want" to operate at depends on several
factors, and a well-engineered MPPT controller can let the PV panels
operate in their ideal voltage range for any given condition, while letting
the battery voltage be what it is going to be.   This changes throughout
the day, and can also be different every day as sun angles and
temperatures, change and PV panels age.

I recommend configuring your array for a voltage higher than your pack, and
then use an MPPT controller to buck down to the pack's voltage, without the
need for pack reconfiguration.  The idea you have about contactors will
likely not work without using a separate BMS for each sub-pack segment.
There are few off-the-shelf BMS' that will allow this kind of
re-configuration safely.

We use a custom-engineered MPPT boost controller on our vans (
https://maxwellvehicles.com/).  It takes 4 panels at about 150 volts total
and uses an MPPT algorithm to boost the PV voltage to the pack voltage
(~375v).  This is another way to do it, but we couldn't find anything
off-the-shelf so we built it ourselves.

Good point.    The "Gizmo"  EV steering was 2 levers on the floor,  I guess 
like some trikes.

I remember the quote from the Tanenbaum  book"The great thing about 
standards is there are just so many to choose from."..

 Anyone who has driven a Ford model T can certainly attest to the challenges of 
having all the controls in the "wrong" locations. (OK, the steering wheel is 
the same as modern cars; but nothing else).

The early EVs also had considerably different controls. How about tiller 
steering? :-)

The tiller also had a hand grip that you rotated forward to accelerate, and 
backward for braking. Backward would give you *plenty* of electric braking 
force!
