The design of an electric drive

 Electrical energy is stored in a rechargeable battery. Devices termed inverters convert the battery’s direct current into alternating current for driving the electric motor. The more efficient conversion is, the longer a car can travel when a battery is fully charged. Finally, an electric motor converts electrical energy into mechanical energy: The e-motor obtains this energy to generate magnetic fields. Their attractive and repellent forces produce a rotational motion.

Other core components of an e-car are the DC-DC converter. It converts the battery’s high voltage (100-400 volts or more) efficiently into a far lower voltage (12 or, if applicable, 48 volts) for electronic components.
