摘要： The present invention provides a power source system that increases the power supply capacity of a power source device and continuously supplies the power necessary for a load device when a power source device stops. A control unit has a state quantity setting unit that sets a first target state quantity indicating a state of charge of the power storage device that is to be a target value when charge and discharge of the power storage device are controlled. When the power source device stops, the state quantity setting unit can change the first target state quantity to a second target state quantity that is to be a target value exceeding the first target state quantity and can increase the target state quantity of the power storage device. As a result, when the power source device stops, charge and discharge of the power storage device are controlled on the basis of the target state quantity exceeding that during the operation of the power source device. Therefore, the state of charge of the power storage device can be improved over that during the operation of the power source device. As a result, the power supply capacity of the power source device can be increased and the power necessary for the load device can be continuously supplied, in place of the power source device.

摘要： An apparatus, which controls the temperature of a secondary battery formed by combination of a plurality of single cells or a plurality of battery modules each made by series connection of multiple single cells, prevents variations in the temperature or voltage of the single cells or the battery modules, which could otherwise be caused when the secondary battery is heated. A temperature control section controls the quantity of heat by means of which a heater heats a secondary battery formed by combination of a plurality of battery modules made by series connection of multiple single cells. The temperature control section detects a rate of temporal changes in an open circuit voltage of the secondary battery. When a detected rate of temporal changes in open circuit voltage has exceeded a predetermined threshold voltage value, the heater is controlled to thus diminish the quantity of heat used for heating the secondary battery.
