| 发明名称 | Control apparatus and control method for lithium-ion secondary battery | ||
| 摘要 | A control apparatus controlling charge and discharge of a lithium-ion secondary battery includes a temperature sensor obtaining the temperature of the lithium-ion secondary battery and a controller. The controller controls the charge and discharge of the lithium-ion secondary battery to maintain the temperature obtained by the temperature sensor at a level lower than an upper limit temperature allowed in the lithium-ion secondary battery. The controller estimates the amount of precipitation of lithium in the lithium-ion secondary battery and reduces the upper limit temperature in accordance with an increase in the amount of precipitation. | ||

| 主权项 | 1. A control apparatus controlling charge and discharge of a lithium-ion secondary battery, comprising: a temperature sensor obtaining a temperature of the lithium-ion secondary battery; and a controller controlling the charge and discharge of the lithium-ion secondary battery to maintain the temperature obtained by the temperature sensor at a level lower than an upper limit temperature allowed in the lithium-ion secondary battery, wherein the controller specifies a part of a deterioration of the lithium-ion secondary battery as a deterioration due to precipitation of lithium by using a deterioration parameter defining the deterioration of the lithium-ion secondary battery to estimate an amount of precipitation of lithium in the lithium-ion secondary battery and reduces the upper limit temperature in accordance with an increase in the amount of precipitation. | ||
