    摘要： A vehicle includes a charging unit receiving electric power from an external power source and externally charging a power storage unit. When a connector unit is coupled to the vehicle and a state ready for charging by the external power source is attained, a controller predicts degradation ratio of the power storage unit at the time point of completion of external charging based on degradation characteristic of the power storage unit in connection with SOC and battery temperature obtained in advance, and sets target state of charge of each power storage unit based on the battery temperatures so that the predicted degradation ratio does not exceed tolerable degradation ratio at the time point of completion of external charging. Then, the controller controls corresponding converters such that SOCs of power storage units attain the target states of charge.

    摘要： When a vehicle is set to a travel control mode or external charging mode, a vehicle system is activated for executing the control mode to which the vehicle is set. A converter ECU selects one sub power storage unit to be used first after activation of the vehicle system, based on a power storage unit used after preceding activation as read from a memory unit contained in the converter ECU and based on respective states of charge of sub power storage units, and electrically connects the selected sub power storage unit and a converter via a switch circuit. When the vehicle system is activated for executing the travel control mode, the converter ECU updates information about the power storage unit used after preceding activation as stored in the memory unit, to information about the power storage unit used first after the present activation of the vehicle system. When the vehicle system has been activated for executing the external charging mode, the converter ECU maintains the information about power storage used after the preceding activation as stored in the memory.

    摘要： A battery charge/discharge control device (20) includes an input-enabled power adjustment unit (40) having an input-enabled current value calculation unit (42) and an input power limit value calculation unit (44). The input-enabled current value calculation unit (42) uses a battery current value, a battery temperature value, and an estimated charge capacity value at the time “t” upon execution of detection, so as to obtain an input-enabled current value reduction amount per unit time during charge and an enabled current amount recovery amount per unit time when being left uncontrolled. Moreover, the input-enabled current value calculation unit (42) calculates an input-enabled current value Ilim(t) to a battery (10) according to the previously calculated input-enabled current value Ilim(t−1) which has been calculated previously or the only initially set input-enabled current value The input power limit value calculation unit (44) calculates the battery input power limit value so that the input current limit target value obtained in accordance with the input-enabled current value Ilim(t) is greater than an actual battery current value. Thus, the input-enabled power to the battery (10) is adjusted in accordance with the battery input power limit value.
