I've only ever had charging problems at one charger, in Carrizozo, which is out in the middle of nowhere. And PlugShare had months of reports that it was busted. I called the company and they apparently were unaware. I believe the name of the company was something like Fly By Night EVSE Solutions or Harris Energy. Honestly it feels very audiophile-y, but if it can keep Cruft Jr from getting stranded out in hicksville it will have been worth the 10 cents of plastic.

Elviscat posted:Question for anyone, if you have an EV with a 200 mile range, and a 100 mile commute, is it better for the battery to charge to 80% every single day, or charge to 100% every 2 days? I'm assuming the latter because total charging cycles is the most important thing, right? 80% every single day is better for the battery long-term, but long-term the difference is going to be small either way. Plug in every day regardless so that you don't have to keep track, removing that chore is the best value proposition in this hypothetical

I thought all non-tesla EVs had a hidden buffer to where charging to "100%" was fine. The end user shouldn't have to care about these things. The Spark EV's manual basically says to keep it plugged in whenever not in use.

Teslas also have buffers they’re just not the same amount between manufacturers. Ford recommends 90% for regular charging despite having one of the larger buffers IIRC.

It’s really absurd how much Tesla is charging for their cut-rate econo boxes. Are their camera-based rain sensors working as good as the 20-year-old competition yet?

Having owned both I think 63,000 for an M3P is a much better deal than 76,000 for a Mach-E GTPE and that's before the Ford dealership gets their hands on it and marks it up an additional 10k.

Has anyone actually seen some experimental data on how different charging patterns affect battery degradation? I'm sure the manufacturers have it, but despite hanging out for years in the RC circles and following EVs now, I've never seen any actual numbers. I mean everyone knows charging to 100% is bad but how bad? So I finally gave up and tried to dig up some actual research. This is the best I could find in a few minutes  https://www.sciencedirect.com/science/article/pii/S1876610218307537 Which is not particularly helpful because a) Nobody uses only 20% of the battery range and b) even if you did, that's not comparable utility as using 100%. Still, based on this it seems that charging 0-20% is least bad, 80-100% is about the same as 0-100%, and the others are only a little better, if you multiply the 100% cycles by 5 to get the same useful capacity. The individual battery cells are cheap as dirt, so I'm quite surprised there doesn't seem to be more clear data on how realistic charge/discharge patterns affect the cell capacity. You could get like a hundred cells and just go through dozens of cycles every day and have solid data in a few weeks.

So much for that $39,997 Ford F-150 Lightning Pro. Ford raised the prices again by five thousand dollars. https://electrek.co/2022/10/05/ford-raises-2023-f-150-lightning-pro-price-by-5k/ The "old" price (that was just raised a month ago) was $46,974. Now the minimum is $51,974.

Ford saw what people were willing to pay in mark-ups, and since they can't really make the dealers stop they are just internalizing the profit. I'm glad I was able to get my EV6 for no markup before prices jumped. I am thinking about buying an older car with a shot engine next year and doing an EV conversion. I saw a Top Banana dodge charger yesterday and thought of how cool it would be with an electric motor.

Ford's EVs are not priced well compared to Tesla, Polestar and Hyundai at the higher end, and GM and Volkswagen at the lower end. Thanks for the battery advice everyone!

You could get like a hundred cells and just go through dozens of cycles every day and have solid data in a few weeks. The Tesla model 3 LR is a pretty common EV. Its maximum AC charging speed is 11kW. Its power consumption around typical cruising speeds is also close to 11kW. It has a useable capacity of 70kWh (for the most part; I believe the 83kWh new version uses different chemistry?). That's 0.16C charging speed, which is more than six hours. Discharge is also then about six hours, for typical usage. So, if you want to test for typical usage, that's 2 charge/discharge cycles per day. For 5000 cycles, you then need almost seven years. You probably want to build one test rig per cell at that point. A reminder: when we're talk about one "charging cycle" for Li-Ion chemistry, it's 100% of capacity. If you test 45-55 you do it 5 times to obtain 1 "charging cycle".

pun pundit posted:In addition, they performed their tests at a charging rate of 6C, which is above what even Tesla and Porsche do with active cooling, and I didn't see much mention of cooling in the article (I was skimming though).  I only skimmed the paper yesterday as well sit it was like 1AM already. They did mention it was done at 25 deg C but nothing about cooling that I could see. Still, even this could be useful to get an upper bound on degradation if they actually did realistic ranges like 10-90 or 20-80 or something. Their worst case is 15% degradation in 2000 cycles while charging at 6C. Tesla allows up to 30% in 100k miles which is just ~350 cycles.

mobby_6kl posted:6C is around the peak you might see on a 350kW charger, no? Still, 6C discharge is pretty nuts, that's drone territory For a 60kWh pack (gross) if it charges at 350kWh, that would approach 6C yeah. I don't know if any EV can do that.

Yeah you're right, I thought something like the EV6 could get close but the pack is a bit larger and it's peaking a round 250kw only, so 3C or so Anyway, if anyone wants to give a a $50k grant, I'll do some testing

Charging is all managed anyway, so whatever theoretical degradation from charging x amount at y rate doesn't have much real world application except for maybe on an old leaf.

I don't think it's ultimately a big issue for adoption but it genuinely bothers me that EVs are sold with an advertised range that you are then told you're not allowed to reach except on special occasions because it'll damage the battery.

I don't fast charge often but I haven't had any connection issues when I do. Considering it cost about .02 worth of materials it seems like a worthwhile investment. Regarding the Grizzl-E, I also have one and can confirm that it's really well built and works flawlessly with my Bolt. I have mine set for 40 amps on a 50 amp circuit. It works great on my wife's Kona as well.

Back from the service center for the second recall. i guess they were able to upgrade the software in the 90 minutes they had it. Plus a 90-minute round trip. The Bolt has a little toggle switch in the settings for over the air updates. I wonder what model year GM is going to figure out how to actually do this.

I think the issue is overstated and a lot of EV owners just really baby their cars. We rented an ID4 on Turo that I'm pretty sure had only been fast charged on free EA credit and had rental conditions requiring it to be returned at 100% charge. It had 30k on it and was fine.

If you've come from a Leaf then you're always going to have the battery degradation at the back of your mind even if it doesn't really apply to the more modern models.

I have the car set to 100% right now because my wife is going to drive it a couple hundred miles tomorrow. Am I doing real damage? How bad is it? Is it bad that I’ve done this 10 times this year or is it only a problem if I do it a few hundred times? I don’t know, the manufacturer won’t tell me! All they say is I’d better not do it!
