Desulfation of a primary battery of an on-board power system of a motor vehicle takes place during operation of an internal combustion engine using electrical energy transmitted to the primary battery front the internal combustion engine. When the internal combustion engine is switched off, or otherwise not operational, desulfation of the primary battery continues using a secondary battery wherein electrical energy is transmitted to the primary battery from the secondary battery.
