Q: What are some basic components necessary for a BEV?
A: Motor, batteries, controller, and charger.
Q: What do they do?
A: The motor converts electrical energy to kinetic energy to drive the vehicle. The batteries chemically store electrical energy for powering the motor. The controller controls the flow of electrical energy from the batteries to the motor. And, the charger delivers the energy necessary to charge the batteries in a controlled manner from an AC power source.
