Abstract: A power supply system includes a controller. The controller is configured to; a) control charging and discharging of an electrical storage device upon reception of an output of a current sensor and a voltage sensor, b) calculate a control current value by subtracting an offset value from a detected value of the current sensor, c) calculate a first determination result and a second determination result, respectively obtained by determining whether the electrical storage device is being charged or discharged based on the control current value, and based on a change in a remaining amount of charge of the electrical storage device, and d) when the first determination result and the second determination result differ from each other, change the offset value such that the first determination result coincides with the second determination result.

Abstract: When a voltage value of an electrical storage device becomes higher than a predetermined voltage value for identifying an overcharged state of the electrical storage device, calculation of a heat generation amount of the electrical storage device based on a current value is started. When the calculated heat generation amount is larger than a predetermined amount, it is determined that the electrical storage device is in an abnormal state (abnormal state related to heating). Because the electrical storage device enters an easily heated state when the voltage value becomes higher than the predetermined voltage value, the heat generation amount may be monitored by starting calculation of the heat generation amount. Once the voltage value becomes higher than the predetermined voltage value, irrespective of a high/low relationship between the voltage value and the predetermined voltage value, the abnormal state may be determined by monitoring the heat generation amount.
Abstract translation: 当存储装置的电压值高于用于识别蓄电装置的过充电状态的预定电压值时，开始基于电流值的蓄电装置的发热量的计算。 当计算出的发热量大于预定量时，确定蓄电装置处于异常状态（与加热有关的异常状态）。 因为当电压值变得高于预定电压值时，蓄电装置进入容易加热的状态，所以可以通过开始计算发热量来监视发热量。 一旦电压值变得高于预定电压值，与电压值和预定电压值之间的高/低关系无关，可以通过监视发热量来确定异常状态。

Abstract: Power storage system includes battery containing an electrolytic solution, and ECU that controls permission and prohibition of charge/discharge of battery based on inside temperature of battery. ECU sets determination temperature equal to or higher than freezing point of the electrolytic solution and determination temperature higher than determination temperature. ECU prohibits charge/discharge of battery when inside temperature falls below determination temperature while the electrolytic solution is in a liquid state, and cancels the prohibition of charge/discharge of battery when the electrolytic solution turns into the liquid state from a state in which the electrolytic solution is at least partially solidified, and when the temperature of battery exceeds determination temperature.

Abstract: In a hybrid vehicle, an ECU executes a forced charging control for forcibly charging a battery by using an engine and a vehicle driving device in a case where a remaining capacity of the battery is equal to or less than a predetermined value. In a case where an evaluation value shows a degree of deterioration of the battery attributable to excessive charging, the ECU uses a first electric power as an electric charging power for charging the battery when an absolute value of the evaluation value is equal to or lower than a first threshold, and uses a second electric power falling short of the first electric power as the electric charging power for charging the battery when the absolute value of the evaluation value is higher than the first threshold in a case where the forced charging control is executed while the hybrid vehicle is stopped.
