A battery management unit includes a plurality of monitoring IC chips each configured to detect at least one operating parameter of at least one battery cell or battery module, which has a predetermined number of battery cells and is connected to a first bus. The battery management unit further includes a control unit and a basis monitoring IC chip which is likewise connected to the first bus and is configured to communicate with each of the monitoring IC chips via the first bus. The basis monitoring IC chip and the control unit are connected to a second bus and are configured to communicate with each other via the second bus. The basis monitoring IC chip and the control unit are arranged on a common circuit board.
