Abstract
A motor vehicle includes an high-voltage power system, a multi-battery system including energy stores for supplying power to an electric drive motor, and switching units connecting the energy stores to the power system. A control device detects a state of charge of each energy store and to selectively connect and/or disconnect the energy stores as a function of their state of charge during travel to and from the power system. The switching units include each contactors to disconnect the energy stores on a plus side and on a minus side from the power system, with only either the positive side or negative side of each energy store including a contactor configured to switch when a load is greater than a minimum load, whereas the other one of the positive and negative sides includes a contactor that is adequate only for a load demand which is less than the minimum load.
