How Regenerative Braking Actually Works

From braking to energy recovery

During deceleration, the electric motor can operate as a generator. Vehicle kinetic energy is converted into electrical energy and sent to the high-voltage battery.

Why the brake pedal can feel different

The vehicle may combine regenerative braking with friction brakes. Control software determines how much braking torque comes from regeneration and how much comes from the conventional brake system.

What technicians should watch

Useful diagnostic parameters can include regenerative torque, battery state of charge, motor speed, brake pedal request, brake pressure and battery temperature, depending on the vehicle.

When regeneration is limited

Cold batteries, high state of charge, thermal protection and certain traction or stability conditions can reduce regenerative braking.
