Good electric car battery standard would solve almost all of the problems of electric cars.<p>1. The battery is where most development happens and where it&#x27;s most needed. So you don&#x27;t have to worry about your car getting too old too fast. Just get fresh battery.<p>2. Range: just swap the battery if you run out of juice. They could be rented like gas bottles are at service station.<p>3. Battery charge lifespan.<p>4. Potentially emerging fuel cells. They are just a way to burn something into electricity. Why do you care what kind of black box feeds you car some current?<p>How could this be done? Build robots at service stations that lift a battery pack into the bottom of the car. Good place could be where the spare wheel currently goes. Bottom of the trunk. You could steal mechanical locking from intermodal containers, just scale it down. And electric connectors could be upscale speakon connectors stolen from pro audio.
