本發明有關一種串聯電池組,尤指一種具平衡控制的串聯電池組。The invention relates to a series battery pack, in particular to a series battery pack with balance control.
隨著現今電子科技高度發展,高電壓的串聯電池組已廣泛應用於電動車、油電混合車以及工業備用電池等領域。詳細來說,由於該串聯電池組內每一電池的製造狀態均有差異,導致每一顆完美出廠的電池內的各項數值也必然存在些許誤差容許範圍內的不相同,容易造成該串聯電池組於放電、充電以及待機等狀態發生不平衡的問題。With the rapid development of today's electronic technology, high-voltage series battery packs have been widely used in electric vehicles, hybrid vehicles and industrial backup batteries.

The charging unit 13 is connected to the battery 11 of the second connection end 143 via the control terminal 141 of one of the routing elements 14 connected to the charging unit 13, and the battery 11 is turned on. The charging power 131 is provided to increase the voltage of the battery 11 being charged, and when the voltage of the battery 11 being charged is greater than the voltage determination data, the control unit 15 controls the charging unit 13 and the routing component 14 Stop charging the battery 11. The intention of the present invention is that although the specifications of the batteries 11 are the same, the self-discharge rate of each of the batteries 11 is different, and it is difficult to have a certain fixed value, so that the self-discharge rate of some of the batteries 11 is difficult to maintain. There is no excessive condition, so the control unit 15 is provided with a standby mode of operation so that the battery cells 11 are synchronized to perform balancing control when the series battery pack 100 is in standby. And, in this state, the power of each of the charging units 13 is obtained from the batteries 11 after being connected in series.

The control unit 15 integrates the voltage data 121 to generate an average voltage data in the charging operation mode. The control unit 15 controls The charging unit 13 temporarily stops charging the battery 11 with the voltage data 121 higher than the average voltage data, and only charges the battery 11 whose voltage data 121 is lower than the average voltage data, and the battery 11 to be charged is charged.
