  • Publication number: 20080061740
    Abstract: Lower order control devices-control plural battery cells configuring plural battery modules. An input terminal of the low order control device in the highest potential, an output terminal of the low order control device in the lowest potential, and a high order control device are connected by isolating units, photocouplers. Diodes 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.

  • Publication number: 20080050645
    Abstract: A cell controller having excellent productivity is provided. A cell-con 80 has 12 ICs IC-1 to IC-2 mounted on a substrate, and these ICs detect voltages of respective cells constituting a cell pack, perform capacity adjustment on the respective cells, and are mounted two by two on rectangular longer sides of a rectangular continuous straight line L-L? defined on a substrate from the IC-1 on a highest potential side to the IC-12 on a lowest potential side continuously in order of potential differences of the corresponding cell packs. Distances between the rectangular shorter sides of the rectangular continuous straight line L-L? are the same. On the cell-con 80, between the IC-1 to IC-12 having different ground voltages, each of the ICs has signal output terminals connected to signal input terminals of a lower order IC respectively in an electrically non-insulated state.
