Yeah standard swappable batteries are nice but as we can see in the cell phone and laptop world, they're very restrictive on design choices. And since EVs are very sensitive to weight and aerodynamics, coupled with the fact that EV makers are trying to put as many batteries into the car as they can, there's just no way to make a one-size-fits-all battery that works for every car.
You'd either need to trade off battery density (which means EV range concerns are amplified) or trade off weight and aerodynamics (which means EV range concerns are amplified).
No general consumer EV maker is going to reduce the total range on their spec sheet just to make it easier to swap a battery that also fits several other cars that they don't make. It's not a smart marketing decision.
- JustSomeNobody 7y ago> You'd either need to trade off battery density (which means EV range concerns are amplified) So, instead of being able to go 300 miles before charging for an hour, I could go 225 but change it out in 5 minutes. I'll take the latter thank you.
- freehunter 7y agoYes, that's why I mentioned the spec sheet. It doesn't matter all the additional benefits you might get if customers are looking at just one number: range.
- r00fus 7y agoWhat about liability ? My car catches fire with a swapped battery. Whose fault is it? Or a less deadly but more probable “I only got 20mi range when it told me 200” Sounds like shocking possibilities.
