Here's a question I've always wanted to ask someone about electric cars: Why don't the companies make cars with detachable batteries, and basically do a battery 'swap' in the charging stations, so that the charging time becomes very little, if people want to?

#33Good electric car battery standard would solve almost all of the problems of electric cars. 1. The battery is where most development happens and where it's most needed. So you don't have to worry about your car getting too old too fast. Just get fresh battery. 2. Range: just swap the battery if you run out of juice. They could be rented like gas bottles are at service station. 3. Battery charge lifespan. 4. Potential…

The idea makes sense. There was an Israeli startup that was trying to do this exact thing that didn't make it. https://en.m.wikipedia.org/wiki/Better_Place
Gogoro in Korea is trying to do this with mopeds (or scooters). There was a lot of hype a year ago, haven't heard much since http://www.theverge.com/2015/1/5/7484171/gogoro-smartscooter... That sounded like a winner to me.

- Building out these charging stations. That's a huge capital outlay for anyone.
- Standardizing batteries, tough when they're in a rapid development phase both in chemistry and form factor.

Tesla did have battery swap stations where the battery would be swapped in around 90 seconds (less time than it takes to fill up a tank)[0]. However, uptake was apparently very small so focus was shifted to building the network of supercharger stations[1].

Why don't electric cars come with a tiny kerosene cabin heater as standard? A small heater would take up little space or weight, could be easily refueled at home so not need a detour to a petrol station, and be much more cost effective than adding extra batteries just to provide cabin heat. Sure, it's not zero-emission, but the efficiency of a kerosene heater can be pretty good (much better than an internal combustio…
No one would be silly enough to cart around a tank of highly explosive liquid in their vehicle.

PG agrees that standards and platforms are not good ground for startups. But I could not find that essay now.
