Re: Ms. Barra's '18 Bolt to-do list

There are two types of changes that happen in any manufacturing plant. Those that are marketed as new features, and those that are quietly rolled into production as invisible engineering changes. I'd be really shocked if the latter weren't already happening on a monthly basis. If you look on GM par...

Re: "Full" battery levels dropping daily

I live in Boston, and it has gotten colder these last two weeks, over what it was the first week I had the car. Would cold temperatures (30's at night, 40's during the day), affect this range to that extent? When the weather gets cold, do you use the cabin heater? That has a significant effect on c...

Re: "Full" battery levels dropping daily

We need to compare the Bolt's battery degradation to the Volt and Tesla. The issues have been minimal with battery loss with those two examples, even with well over 100,000 miles driven in electric mode only. The Volt may not be a good comparison, since it has a very large buffer capacity. Teslas h...

Re: When to recharge?

Late afternoon and evening (17:00 to 21:00) tend to be the higher electricity use time, and also when solar installations provide less or no power into the grid. So that would be the worst time to charge an EV if you are thinking of global or grid-level effects. 06:00 to 07:00 on work days is anothe...

Re: Loss of miles / charge

I stand by my conjecture based on 7 years of experience with 4 different EVs that deep discharge is the biggest enemy of range retention and primary cause of range decline. This is what killed our Leaf1 besides heat, and our Soul EV that's getting a (free) brand-new battery at 47k miles, both resul...

Re: "Full" battery levels dropping daily

I am not talking about longer term degradation of the battery. I am talking about the "full" level being 40-50 miles less on a rather sudden basis. The car is only 6 months old Most modern cars (not only EVs) have range remaining displays. We commonly refer to the ones in our EVs as "...

Re: Loss of miles / charge

If your car has heated seats, using them consumes much less energy than using the cabin heat.

Re: "Full" battery levels dropping daily

Also, is any Bolt battery ever charged at 100% ? My understanding is that the battery management system keeps a certain reserve at the top and bottom of the battery capacity, so the battery never charges all the way to 100% or down to 0%. There’s a footnote at the bottom of the graph that states th...
