In a battery-powered electric vehicle, regenerative braking (also called regen) is the conversion of the vehicleâs kinetic energy into chemical energy stored in the battery, where it can be used later to drive the vehicle. It is braking because it also serves to slow the vehicle. It is regenerative because the energy is recaptured in the battery where it can be used again. The kinetic energy stored in a moving vehicle is related to the mass and speed of the vehicle by the equation E = Â½mvÂ².
