Lower order control devices (IC-1, IC-2, IC-3) control plural battery cells (VB1, ..., VB12) configuring plural battery modules. An input terminal (In) of the low order control device (IC-1) in the highest potential, an output terminal (Out) of the low order control device (IC-3) in the lowest potential, and a high order control device (MPU) are connected by isolating units, photocouplers (F1, ..., F6). Diodes (D2, D4, ZD4) which prevent a discharge current of the battery cells in the battery modules are disposed between the output terminal of the low order control device and the battery cells in the battery module on the low potential side. Terminals related to input/output of a signal are electrically connected without isolating among the plural low order control devices.
