## Why dynamo is not used in electric cars?

Gasoline fuels the internal combustion engine, the energy from which turns belts and pulleys, which in turn creates mechanical energy. An all-electric car does not have such an engine; therefore, the mechanical energy cannot be generated to work the dynamo.

## Why don't they put alternators on electric cars?

In an electric car, the source of power is already electrical, so there's no point converting it to mechanical then back to electrical again. Because all the power to run the alternator comes from the motor. So it would be a net loss of energy.. An alternator us not a perpetual motion machine.
