Question 1

Explain the basic operating principles of regenerative braking.

Accepted Answer

Regenerative braking recovers the energy used to brake by converting rotational energy into electrical energy through a system of electric motors and generators. When the brakes are applied the motor becomes a generator by using the kinetic energy of the vehicle to store power in the battery for later use.
