battery swap thing

@ TJ McDermott

I am skeptical of the battery swap thing for many reasons.

I think it's best chance to get a good start, would be a fleet environment. Like maybe a taxicab fleet.

Unfortunately Tesla doesn't seem to be targeting that environment. Instead Tesla seems to be selling it to the general public.

Some suggest it is a front for a carbon credit scam. That's it is a lot of hype and likely only a token effort will be made.

The giga battery factory could be boon or bust. I think there is a big potential. If it proves successful, it could make Tesla a household name.

@Charles: There are 2 sides of it. Weight can be a problem in some cases where as once you get used to it then it will not be such an issue. So it depends on what your requirement is and how well you are going to adapt towards it.

"But since they don't have a liquid cooling system"

I'm lost. Not sure what you're trying to say. Tesla batteries or the cells themselves?

If I recall correctly, I think you said similar things before that confused me.

If I understand correctly.
Tesla traction batteries do have a cooling system. Standard automotive coolant like glycol is used to cool the batteries. The battery coolant glycol is further cooled by a Freon system.

Should They?

I think this is the defining point:

"If you're going to talk about building the biggest battery factory in the world, you first need to have a product that appeals to the mass market."

The public does not have a confidence in EVs yet and the price tag cut in half mentioned in the article is still beyond the reach of the average consumer (if I'm average)...

26650 cells might make better sense - you would have roughly half as many cells.

It's hard to say how much extra weight, if any, is involved, tekochip. No one else makes a battery the size of their's, so it's hard to say. But since they don't have a liquid cooling system, I can only assume that they compensate for any extra weight that would otherwise be associated with the 18650s.

They really need to break away from the 18650 case, how much extra weight is included in building packs from such small cells?

The first step

This is the first step, and it is a good one.  There are several other steps to make EVs work though.

His plan to do battery swaps at public stations (and the timed demonstrations against filling a gas tank the regular way) are another important step.

Put these two together, and he's most of the way to easy acceptance of EVs.
