How do electric cars work?

This is our simple take on this very valid question:

• Power is converted from the Direct Current battery, to Alternating Current for the electric motor
• The accelerator pedal sends a signal to a controller, which adjusts the speed of the vehicle by changing the frequency of the power from an invertor to the motor
• The motor connects and turns the wheels through a cog
• When the brakes are pressed, or the car is decelerating, the motor becomes an alternator and produces power which is sent back to the battery
