How does an electric motor power an electric car?

An electric motor powers an electric car by converting electrical energy stored in the vehicle's battery into mechanical energy to drive the wheels.1

The process functions through the following steps:

• Power Conversion: Batteries typically supply direct current (DC). A power inverter converts this into alternating current (AC) to drive the motor.2
• Control: The driver uses an accelerator pedal to signal the system to vary the output voltage, which controls the motor's speed and power.2
• Propulsion: Because electric motors provide high torque, they often eliminate the need for conventional gear-type transmissions, allowing for efficient acceleration.12
• Regenerative Braking: When braking, the motor operates in reverse as a generator. It converts kinetic energy back into electrical energy, which is then stored in the battery to extend the vehicle's range.12

This system is highly efficient, requires less maintenance than internal-combustion engines, and provides a quieter driving experience.1
