Series-connected rechargeable cells, series-connected rechargeable cell device, voltage-balance correcting circuit for series-connected cells |
摘要 |
[Object] There is provided series-connected rechargeable cells in which a large number of cells are series-connected and that makes it possible to improve performance on operations such as assembly or exchange and to perform speedy and smooth voltage-balance correcting for all cells. [Means for Solution] Series-connected rechargeable cells includes: a large number of rechargeable cells that are series-connected, and that are divided into a plurality of series-connected cell groups placed continuously in order of connecting; and a voltage-balance correcting circuit that balances the voltages of the cells, and that is provided with an inter-cell voltage-balance correcting circuit that performs voltage-balance correcting between adjacent cells in each of the cell groups and an inter-group voltage-balance correcting circuit that performs balance correcting of series-connection voltages of the cell groups by AC-coupling formed with a transformer coil and a switching circuit. |
