Regenerative braking

How it is used

Often called regen. Drivers choose regen levels, and strong regen allows one-pedal driving. Because regen does much of the slowing, EV brake pads last longer, but the discs can corrode from lack of use.

Example sentences

1. Regenerative braking recovered about 15 percent of the energy on the city test route.

2. When the battery is full, regenerative braking is limited, so the car feels different on long descents.

• traction motorThe electric motor that drives the wheels of an electric or hybrid vehicle. Most modern cars use permanent magnet synchronous motors, though induction motors are also used.
• electric vehicleA vehicle driven only by one or more electric motors that take energy from a rechargeable battery. It has no fuel tank and produces no exhaust emissions while driving.
• brakeA device that slows or stops a vehicle by pressing a friction material against a rotating disc or drum. Most cars have hydraulic disc brakes at the front.
• state of chargeHow full a battery is at a given moment, shown as a percentage of its usable capacity. The battery management system estimates it continuously.
• hybrid vehicleA vehicle that combines a combustion engine with one or more electric motors and a battery. A full hybrid charges its battery from the engine and from regenerative braking, not from a plug.
