Won't it be inefficient to convert engine displacement - > charge - > vehicle displacement again? I wonder if it is instead possible to have a universal batter

I wonder if it is instead possible to have a universal battery installer. A universal battery pack that serves the same purpose as what you suggest, the size of a small engine + petrol tank.
One that is cross compatible with all electric cars. (the hard part) maybe it can be a section in the boot itself. So when not in use, it is simply boot space. (will be easier to be universally. Compatible too) as long as there is a power in the boot.
You pick one up from a store and as long you return it to another store inside of a few hours, you are only charged the cost of electricity + battery rental.
- AnthonyMouse 8y agoThe trouble with this is that the amount of battery it takes to be equivalent to a tank of gasoline weighs on the order of a thousand pounds. They only get away with it as part of the car because the electric motor is light (~70 pounds compared to ~400 for a gasoline engine) and you also eliminate the fuel tank, transmission, exhaust system, etc. The battery is also large enough that the shape is dictated by the shape of the car. Making them easily swappable wouldn't be easy. The more likely solution is to just increase the number of charging points, and then have models specifically designed with larger batteries for people who need longer ranges. The existing ranges are already sufficient for typical usage. Most people rarely drive more than 300 miles in one day, and almost never drive more than 600 miles in one day, so we're already at the point that on 99% of days you don't have to care about it at all and then on the occasional road trip you have to stop for an hour out of every five to have a meal and charge the vehicle.
