Possibly, but all the above is yes, no, maybe conjecture based on maybe not exactly the same chemistry. Since GM has all the Bolt charge data, they made some deductions/educated guesses that the Bolt fires could be traced to two manufacturing defects made more likely to fail by repeated deep discharges and recharging to 100%. It may never be conclusively proved if those batteries without the defects are being harmed by that cycle. Maybe yes, maybe no.I've been driving my Bolt in Winnipeg since 2017. In the summer, I can go 500km on a charge in the city. In the winter, that drops to half of that (heater, defog, heated seat, etc). The guess-o-meter that is being talked about takes a lot of things into consideration and mine will change overnight. It appears to consider battery conditioning (when it's cold out) as a loss in mileage - expecting that it will need to keep warming the battery even when you're not plugged in.
I've attached what the car draws from my 220v charger. You can see that once it's charged, it takes a 10A draw a couple times and hour for about 15 min (this is at -25C)
Lastly, although I'm no expert on batteries, my understanding is that 110v is the best for preserving your battery. 220v is the next best and you should avoid the fast DC charging unless you really need it. Kinda like the RC modellers who charge their batteries at higher rates - it gets them flying faster, but they don't survive as many charge cycles.
