Abstract

A method for operating an energy storage device with at least one first and at least one second energy storage element in a motor vehicle, wherein the first and the second energy storage elements are connected in series to provide a nominal voltage of the energy storage device, wherein when a charging condition indicated for charging an energy storage device by a motor vehicle-independent energy source as fulfilled, the first and the second energy storage elements are connected in parallel to the motor vehicle-independent energy source, wherein a charging voltage is provided by the motor vehicle-independent energy source for charging the energy storage device, which is lower than the nominal voltage of the energy storage device with a connection in series of the first and of the second energy storage element.
