Abstract

A battery system comprises at least two modules which include a plurality of battery cells, with each module being associated with a cell voltage detection unit which is connected to a central controller via a common communication bus. Each module additionally includes a module voltage detection unit which is connected to the central controller and is configured to separately detect the voltage of the associated module.
