Question 1

What is the difference between a battery electric vehicle and a hybrid electric vehicle?

Accepted Answer

A battery electric vehicle is similar to a hybrid electric vehicle, except that a BEV does not have an internal combustion engine. A large rechargeable battery provides power to one or more motors that are large enough to propel the car at all speeds. This is done without assistance from an ICE, unlike a hybrid electric vehicle.
