How does an electric vehicle work?
Charging a Detroit Electric car, 1919. An electric car is powered by an electric motor instead of a petrol engine. The electric motor gets energy from a controller, which regulates the amount of power—based on the driver’s use of an accelerator pedal. The electric car (also known as electric vehicle or EV) uses energy stored in its rechargeable batteries, which are recharged by common household electricity. Thus an electric vehicle will have three basic components : Energy Storage Unit Controller Propulsion system The energy storage unit will have a way to store power. A chemical battery is the most common energy storage technology currently, although it can be different - for example - A fuel cell (which gets its electricity from hydrogen rather than a battery pack), can be used instead of a chemical battery as the energy storage unit. The controller acts as a pipeline or gateway to the electric motor.. The controller will do other things too - it moderates the...
