I know for a fact that you can't put 240V into a 2014 model stock EVSE.

Don't ask........

As you will find searching that forum, the range is an estimated guess based on the last few driving/charge cycles. So it will take a few days for it to reflect your driving conditions. There are various ways to get an estimate of the current battery usable capacity. If you don't have a fancy ODB el...

And if you use the energy dashboard % and kwh used, don't take these numbers if you have had partial recharge during that period.
I noticed that when you do, results can be off

I am down to 14kWh, so I will be interested to hear what they tell you

Are they charging you anything for the evaluation of your battery capacity?

Thanks

Well, the nominal capacity (20 or 21kwh) has definitely nothing to do with the % degradation, as you never got to use that full capacity in the first place. The usable capacity value does not officially appears any where, but is believed to be around 18.4 kWh From the warranty terms, GM is the only ...

And remember, the range estimate has nothing to do with the battery charge level. It is just a guess on how many miles you may be able to do on a full charge, based on the last few days of use. So when it changes significantly, it is almost in every case, because the driving conditions have changed ...

They may also have expired as of today

In my experience, the guess O meter range is based on about the last 4 days of driving / charging cycles.

Your better than EPA driving is now compensating for your loss in charge capacity

Given all that is going on in this world and here (in the US) in particular, I never really had a doubt
