| description | PROBLEM TO BE SOLVED: To provide a capacity control circuit for a battery pack capable of properly equalizing battery cells Ci (i=1 to n) comprising a battery pack 10.SOLUTION: A capacity control circuit for a battery pack 10 comprises: transformers Ti; primary side switches SW1i; and secondary side switches SW2i, etc. More specifically, a series connection body of a primary side coil w1i and the primary side switch SW1i is connected in parallel for each of battery cells Ci, and each of series connection bodies of a secondary side coil w2i and a diode Di is connected in parallel via the secondary side switch SW2i. In this configuration, a processing is performed to select a battery cell having a maximum voltage and a battery cell having a minimum voltage among battery cells Ci. Then, an equalization processing of operating the primary side switches SW1i and the secondary side switches SW2i is performed so as to supply electric power from the battery cell having the maximum voltage to the battery cell having the minimum voltage via the transformers Ti. |
