Provided is an all-solid-state lithium ion battery control system capable of improving safety. An all-solid-state lithium ion battery control system installed in a vehicle is provided with: an all-solid-state lithium ion battery connected to a motor for driving the vehicle; and a control unit that, during normal operation, controls the input/output of a current to/from the all-solid-state lithium-ion battery so as not to exceed a first prescribed SOC of the all-solid-state lithium-ion battery, the all-solid-state lithium-ion battery containing lithium titanate in the negative electrode and containing lithium titanate in the negative electrode. The control unit accumulates the number of seconds or the current value at which the amount of charge of the all-solid-state lithium ion battery exceeds 100% of SOC due to the overcurrent, calculates a limit SOC reduction amount on the basis of the accumulated value, calculates a second predetermined SOC on the basis of the limit SOC reduction amount, and controls the all-solid-state lithium ion battery on the basis of the second predetermined SOC.

    提供能够提高安全性的全固体锂离子电池控制系统。一种设置于车辆的全固体锂离子电池控制系统,具备:全固体锂离子电池,与车辆的驱动用马达连接;以及控制部,在通常的运转中,以不超过全固体锂离子电池的第1规定SOC的方式,控制向全固体锂离子电池的电流的输入输出,全固体锂离子电池在负极中包含钛酸锂,控制部对由于过电流而全固体锂离子电池的充电量超过SOC100%的秒数或者电流值进行累计,根据累计的值计算界限SOC降低量,根据界限SOC降低量计算第2规定SOC,根据第2规定SOC进行全固体锂离子电池的控制。
