    • A battery system having a battery string configured by connecting in series a plurality of battery units includes: an SOC detection unit for individually detecting states of charge of the plurality of battery units; and a charge-and-discharge control unit for individually charging and discharging the battery units, based on a full charge capacity of each battery unit and each state of charge of the battery units individually detected by the detection unit, upon the battery system being in no load state, the control unit individually charges and discharges the battery units so that the states of charge of the battery units are approximately equal with each other when the battery units are in a discharge end state and so that a difference between the states of charge of the battery units is relatively large when the battery units are approximately in a full charge state.
    • 具有串联连接多个电池单元的电池串的电池系统包括:SOC检测单元,用于分别检测多个电池单元的电荷状态; 以及充放电控制单元,用于基于每个电池单元的完全充电容量和由所述检测单元单独检测的电池单元的每个充电状态,对所述电池单元进行单独充电和放电,所述充电和放电控制单元在所述电池系统处于 无负载状态时,控制单元分别对电池单元进行充电和放电,使得当电池单元处于放电结束状态时电池单元的充电状态彼此近似相等,并且使得充电状态之间的差异 当电池单元大约处于完全充电状态时,电池单元的相对较大。
