    • A first threshold that is lower than a progressively deteriorating SOC that is an SOC in which a battery performance of the lithium ion secondary battery deteriorates when the lithium ion secondary battery is stored and a second threshold that is greater than the progressively deteriorating SOC are preset. A computer controls a switch provided between electric wires and the lithium ion secondary battery, an electric power supply source that supplies electric power necessary to charge the lithium ion secondary battery and a load that consumes electric power discharged from the lithium ion secondary battery are connected to the electric wires, such that a charging operation for the lithium ion secondary battery is continued from the first threshold to the second threshold when the lithium ion secondary battery is charged based on value of the SOC of the lithium ion secondary battery, the value of the SOC is transmitted from a monitor device that detects the value of the SOC of the lithium ion secondary battery and that controls the switch such that a discharging operation for the lithium ion secondary battery is continued from the second threshold to the first threshold when the lithium ion secondary battery is discharged.
    • 预先设定低于逐渐劣化的SOC的第一阈值,SOC是作为锂离子二次电池的电池性能在存储时劣化的SOC,并且预先设定大于逐渐劣化的SOC的第二阈值的SOC。 计算机控制在电线和锂离子二次电池之间提供的开关,提供对锂离子二次电池充电所需的电力的电力供应源和消耗从锂离子二次电池放电的电力的负载连接到 使得当基于锂离子二次电池的SOC的值对锂离子二次电池进行充电时,锂离子二次电池的充电操作从第一阈值继续到第二阈值, 从检测锂离子二次电池的SOC的值的监视装置发送SOC,并且控制开关,使得锂离子二次电池的放电操作从第二阈值持续到第一阈值时,锂离子 二次电池放电。
