A battery system for an electric vehicle. The electric vehicle includes a plurality of serially interconnected battery modules, each battery module having at least two battery cells interconnected in parallel, a master control unit for supervising the battery modules, and a slave control unit for supervising the battery modules. A master supervision unit having master sensors for detecting measured values of the battery cells and of the battery module and a slave supervision unit having slave sensors for detecting measured values of the battery cells and of the battery module are assigned to each battery module. The master supervision units communicate with the master control unit, the slave supervision units communicate with the slave control unit, and the master control unit communicates with the slave control unit.
