Tesla Car Batteries

Post by jennyjj01 » Sat Oct 02, 2021 11:07 pm

Caught a glimpse of something amazing* :shock: :shock: :shock: about Teslas ( and other E cars) today on "Secrets of the supercars"

Their battery packs comprise >8000 of Panasonic 18650 batteries just like the ones in our torches, laptops and security lights.

I had it in my head they were something much more specialised and proprietary with great big custom made cells. But no. A honeycomb of dinky little ordinary torch batteries. ... and some clever water cooling.

* Well it amazed me. Who'd have imagined a car running on a quarter of a tonne of ordinary torch batteries? :shock: :geek:

Not the sort of thing I watch. It was just on in the background and my ears pricked up when they mentioned "18650 batteries" after we were discussing them. Then I just had to google "Tesla 18650" Was frankly gob-smacked. I'd always thought e car batteries would be a few great big chunks of whatever they use, lithium, nickel, whatever. Not thousands of (something like) AA batteries (Yes. I know 18650 is not AA)

Yeah, 18650's are a bit of a thing - all sorts of videos etc. on building your own power wall (the Tesla PowerWall is built from the same batteries) or just power banks. Just about all battery drills etc. are populated with them these days.
