Just to be safe until GM says otherwise, I'm not charging our 2017 Volt to 100% anymore and I will only charge when we are awake. Hopefully GM will address all these issues/concerns so we can get back to charging as usual.
My 2017 has a 18.4KWh battery. I have noted on several occasions that I can only use 14KWh of that battery. There also appears to be a small buffer at the bottom - I'm estimating 0.4KWh - to allow the car to dig into the battery when the ICE either isn't sufficiently powerful or under hard acceleration when the ICE can't spin up fast enough. This leaves 4KWh unused. Knowing that LiOn batteries don't like to be discharged or fully charged I'm working on the assumption that this buffer is split in half with 2KWh at the top and at the bottom.That’s not true. My 2019 charges to 95% and I seriously doubt that it’s any different for any other gen-2.
We may never see another vehicle with the near perfect mix of electrification, worry-free range anxiety, and price point (I bought my new Volt for $21k after rebates and incentives). The CT6 Plugin definitely has more luxury and cabin space, but at a much higher price. Come on GM, give us more choices already... we’ve been waiting foreverYeah when I realized that the original volts were engineered to stop charging at 80% capacity and use their ICE to recharge starting at 30% capacity I realized that the batteries should last a really long time. It is the kind of over-engineering for longevity that I appreciate and something only reasonably possible with the ICE engine to recharge on the fly vs. a straight EV. My 2012 Volt still seems to have the original KWh/mileage capacity w/ 100k + miles although it varies a lot based upon driving style and external weather factors. I can get anywhere from 2.5 to 4+ miles per KWh depending upon how much the battery needs to be heated/cooled and whether I need to use the heater to defrost it.
just dont know if its good, normal, or badThe Volt uses more of the battery capacity as the battery degrades to make degradation unperceivable without using instrumentation. Your range should stay the same for a very long time. My guess is that range wont change for most cars during the Voltec warranty. Eventually degradation will exceed the buffer values and range will decrease with degradation after that. Very old Volts will be used as hybrids daily, but that's after being on the road for ten years or so. Any insurance claim would total the car at that point.
