Abstract
A method and electrical system for controlling the power supply of an electric motor, in particular the electric motor of a vehicle that can be electrically driven, includes a control device that controls the power supply of the electric motor by an energy store. The energy store comprises a plurality of modules that are exposed to stress due to repeated charging and/or discharging and undergo an aging process as a result of said stress. In order to decouple the service life of the energy store from the service life of a vehicle, for example, the control device controls the charging and/or discharging of at least two modules differently such that said modules exhibit a stress difference so as to selectively reduce the aging process of the module being exposed to less stress.
