| 摘要 | A battery system has a battery module including a number M of series-connected batteries. The battery system is further provided with a number N (1<N≦M) of charge equalizers, each of which once connected to a battery, causes the battery to be charged and/or discharged to achieve charge equalization. A control device is configured to determine for each battery if it requires charge equalization based on a state of charge (SOC) of the battery, compare a number L of the batteries that require charge equalization and the number M, and based on the comparison result, cause the battery system to be shut down, or the one or more batteries that require charge equalization to be connected to corresponding charge equalizers. A selective switch module is used for connecting the one or more batteries that require charge equalization to corresponding charge equalizers, respectively. | ||

| 主权项 | 1. A battery system, comprising: a number M of battery cells connected in series; a number N of charge equalizers, each of which, once connected to a battery cell, causes the battery cell to be charged and/or discharged for achieving charge equalization, wherein 1<N≦M; a control device configured to: determine if one or more battery cells require charge equalization based on a state of charge (SOC) of each battery cell,compare a number L of the battery cells that require charge equalization and the number N of charge equalizers, andbased on the comparison result, cause the battery system to be shut down, or cause the one or more battery cells that require charge equalization to be connected to corresponding charge equalizers; and a selective switch module for connecting the one or more battery cells that require charge equalization to corresponding charge equalizers, respectively. | ||
