Regenerative braking is a kinetic energy recovery system that transfers the vehicle’s energy into electricity as it slows down. With a traditional hydraulic braking system, the friction between the brake pads and the discs produces large amounts of heat. Instead of letting this energy go to waste, regenerative braking puts it to better use.
When someone driving a hybrid or EV activates the brakes, electric motors recover the kinetic energy generated by the friction. This recovered energy is converted into electricity that charges the vehicle’s batteries, improving its performance, energy efficiency and overall range in one fell swoop.
Auto manufacturers have utilised four main types of regenerative braking systems over the years:
Electromagnetic An electromagnetic regenerative braking system connects the driveshaft to an electric generator, which uses magnetic force to restrict its rotation and slow the vehicle down while generating electricity. This can recharge EV batteries or power various auxiliar y functions, such as audio and climate control.
