A reference to this perhaps?

Correct. There is a sticker on the pack. It's 57kWh.
Interestingly, at about 17:00 in the video he states that this is a "second-design battery" for the Bolt. I wonder if the "first-design battery" might have had a different capacity.DaveinOlyWA said:got a time stamp for that?arnis said:Correct. There is a sticker on the pack.

The "Rated energy" (label seen at 27 minutes into the video) is likely the rated available capacity in kWh, not total battery pack capacity.arnis said:...There is a sticker on the pack. It's 57kWh.

Of course I'm interested.GetOffYourGas said:No, Guy. I'm talking about your interest in an EV. At least I assume you are interested, since you are very active on this forum.GRA said:Like many Californians my age I've been interested/involved in environmental issues since the Santa Barbara blowout in 1969, and energy security since Desert Shield, which was when I got seriously involved in designing and selling off-grid (PV/Wind/microhydro) systems.

They don't have to meet them at a lower cost, just a comparable one, if they are to replace ICEs for the general public (and me). Personally, I'd be perfectly happy to give up car ownership entirely, and the day that I have access to a long range ZEV from a mobility service will be the day I seriously start considering doing just that. Thankfully the millennials are less enamored of car ownership than preceding generations, and assuming that trend continues, then EVs combined with AVs will radically reduce the size of the fleet, if not the number of vehicles built or miles traveled.GetOffYourGas said:All of your lifestyle choices are to be commended. I *try* to a degree, but nothing like you have done, and I applaud you for it.
No, I was talking about EVs. That they meet your transportation *requirements* is a given. That they meet them as well as your ICEV does and do so at a lower cost (purchase and fuel/maintenance) is where the rest of your argument breaks down.
No, I want an EV for ZEV transportation at comparable cost, although lower would be great. But if ZEVs don't provide comparable capability at a comparable(or lower) price, then absent government mandates or a major spike in the price of oil the general public simply won't switch. Here's about the capability we need, but at a price most people can afford:GetOffYourGas said:You want an EV for cheaper transportation, and that's all. You don't want to sacrifice anything in the process. Not that there's anything wrong with that - plenty of people feel that way. And when the EVs get to that point, we will see a huge spike in adoption.

If they had I wouldn't be around to care, and you wouldn't care either, but thanks for the thought They did limit themselves to me, though, although for other reasons. But it's not children per se that I'm worried about, it's the number of human beings, as we are the major source of environmental stress.GetOffYourGas said:As for seeing having children as an "undue" stress on the environment, let's just say that we don't see eye-to-eye there. I'm glad that your parents didn't feel that way, too.

But I have driven the Bolt EV. And this is what I saw after driving 470.6km.
The cell chemistry in the B olt means the fast charging will be slower and taper earlier. But it has higher energy density = a bigger battery in the same space.Jeff N said:...it’s more about cell construction than cell chemistry. They optimized the thickness of the cathode, anode, and conductive copper and aluminum collector foils in the Bolt cells to get the highest energy density whereas in the Volt they aimed to enable higher power capability.
The cell specifications, such as we know them from unofficial sources, are quite different. The Bolt cells may be max 2C continuous discharge with a 10 second peak discharge rate of 3.5C whereas the Volt cells may have been rated for 10C continuous discharge. In return for that lower design power, Bolt cells appear to be quite a bit more energy dense.
