A circuit arrangement (10) for a battery (11) which supplies both the drive device (18) and the rest of the vehicle's electrical system (16) and consists of a multiplicity of battery cells (12) is proposed for vehicles, in particular submarines, the battery (11) being divided up into a plurality of battery units (13) with sub-voltages associated respectively therewith, and the sub-voltage of at least one of the battery units (13) for supplying the electrical loads of the vehicle with electricity, apart from the drive device, being also reduced. Here, at least one battery unit (13) is divided into a plurality of sub-units (14) in accordance with a preselectable number of battery cells (12), it being possible to connect the electrical loads (16) of the vehicle to the sub-units (14) at predeterminable time intervals via a change-over device (15). <IMAGE>
