Method of manufacturing a battery pack to minimize circulating current |
摘要 |
A battery pack has a plurality of assembled batteries connected in parallel. Each of the assembled batteries has a plurality of cells connected electrically. A circulating current in each of the assembled batteries is calculated from an open circuit voltage of the assembled battery that varies according to the number of the cells connected in series, a value indicating a charge state of the assembled battery that varies according to the number of the cells connected in parallel, and an internal resistance of the assembled battery. The number of the cells connected in parallel and the number of the cells connected in series in each of the assembled batteries are numbers determined under the condition that the circulating current should not exceed an allowable current value for the assembled battery. |
