An objective of the present invention is to provide an all-solid-state lithium-ion battery control system capable of improving safety. To achieve the objective, the all-solid-state lithium-ion battery control system provided in a vehicle includes: an all-solid-state lithium-ion battery connected to a driving motor of the vehicle; and a control unit controlling the input/output of a current to the all-solid-state lithium-ion battery so as not to exceed a first prescribed SOC of the all-solid-state lithium-ion battery, with respect to a common operation, wherein the all-solid-state lithium-ion battery includes lithium titanate in an anode. The control unit integrates the number of seconds or a current value with which the charge amount of the all-solid-state lithium-ion battery exceeds SOC 100% due to overcurrent, calculates a limit SOC decrement based on the integrated value, calculates a second prescribed SOC based on the limit SOC decrement, and controls the all-solid-state lithium-ion battery based on the second prescribed SOC.

    [과제] 안전성을 향상시킬 수 있는 전고체 리튬 이온 전지 제어 시스템을 제공한다. [해결 수단] 차량에 구비되는 전고체 리튬 이온 전지 제어 시스템에 있어서, 차량의 구동용 모터에 접속된 전고체 리튬 이온 전지와, 통상의 운전에 있어서, 전고체 리튬 이온 전지의 제 1 규정 SOC를 넘지 않도록 전고체 리튬 이온 전지로의 전류의 입출력을 제어하는 제어부를 구비하고, 전고체 리튬 이온 전지는 부극에 티탄산 리튬을 포함하는 것이며, 제어부는, 과전류에 의해 전고체 리튬 이온 전지의 충전량이 SOC 100%를 넘은 초수 또는 전류값을 적산하고, 적산된 값에 의거하여 한계 SOC 저하량을 산출하고, 한계 SOC 저하량에 의거하여 제 2 규정 SOC를 산출하고, 제 2 규정 SOC에 의거하여 전고체 리튬 이온 전지의 제어를 행한다.
