CHARGE CONTROL SYSTEM AND CHARGE CONTROL METHOD FOR BATTERY PACK |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To achieve more appropriate charging in using a plurality of secondary cells as a battery pack. <P>SOLUTION: The present invention comprises: a volt meter 4 that monitors a charging voltage of each lithium ion cell 2; a bypass circuit 3 that is provided for each cell 2 and individually discharges the cell 2; and a controller 6 that operates the bypass circuit 3 for all the cells 2 with charging voltages not less than an average charging voltage when a state where charging voltages of a part of the cells 2 is lower than a predetermined voltage continues for a predetermined time. <P>COPYRIGHT: (C)2013,JPO&INPIT |
