Abstract

The method involves converting recuperation energy of a hybrid vehicle into heat via electrical resistors, when an energy store of the vehicle is charged or when the charge condition of the energy store exceeds a predetermined limit. The heat generated by the resistors is derived by a cooling system of an electric machine and a fluid-cooled internal combustion engine and/or a fluid-cooled transmission in the hybrid vehicle. The energy store is attached to the electric machine.
