| 摘要 |
The invention provides a cell voltage measuring device for a cell module wherein component cells are theoretically divided into a plurality of (n) cell blocks 111 to 11n. A plurality of potential detecting lines extending from respective potential detecting points of each of the cell blocks are provided with potential holding means 12 having capacitor blocks each for holding the potentials of the potential detecting points of the cell block, and cell voltage measuring means 14 for measuring the voltage of the cells based on the potentials of the potential detecting points held by the potential holding means 12. Flying capacitors are provided for each cell block.
