摘要： PROBLEM TO BE SOLVED: To realize an increased travelable distance during an EV travel as well as a protection of a power storage device by correctly detecting a full charge of a power storage device when charged externally.SOLUTION: A charge controller, by dividing a maximum voltage among voltages between a plurality of terminals corresponding to a plurality of respective battery blocks by the number of the battery blocks corresponding to the maximum voltage, calculates average voltage value of battery sells included in the corresponding battery blocks. When it is detected that any of the voltage value among a plurality of the battery cells exceeds a prescribed value, an average value is output by adding an offset value based on the prescribed value to the average value obtained above. A charge controlling part obtains a real average value by performing an averaging processing to the average value by using a sampling value of the average value to which the offset value is added. Based on this real average value, a fully charged state of the power storage device is determined. The charge controlling part variably sets the number of samples of the average value used for the averaging processing according to frequencies of an AC power supplied by an AC power supply.

摘要： PROBLEM TO BE SOLVED: To prevent a secondary battery from being decided as overcharged, due to a manufacturing error of a sensor or its temperature characteristic, at a time of a system start-up after the second battery is charged.SOLUTION: At a time of a system start-up after a high-voltage battery is charged up to a charge-completion voltage V*, the power supply apparatus prevents the high-voltage battery from being charged by switching off a step-up converter until a prescribed time elapses. The prescribed time is determined as a necessary time to reduce a maximum voltage amount of a sensor error, which is generated by an overcharge-sensor error due to a manufacturing error and temperature characteristic of the sensor, from an overcharge-threshold value due to a minimum power consumption even if a motor or the like is not driven. And the power supply apparatus does not decide whether the high-voltage battery is overcharged or not even when an overcharge-determination signal Vo from the overvoltage sensor becomes on-state (S240-S310). Thus, the high-voltage battery is prevented from being erroneously determined as overcharged at the time of a system star-up after being charged.
摘要翻译：要解决的问题：为了防止二次电池由于传感器的制造误差或其温度特性而被确定为过充电，则在第二电池充电之后的系统启动时。解决方案：在高电压电池充电到充电完成电压V *之后的系统启动时，电源装置通过切断步骤来防止高压电池充电直到达到规定的时间。规定的时间被确定为必须的时间，以减少由于由于传感器的制造误差和温度特性而导致的过充电传感器误差而产生的传感器误差的最大电压量，由于过充电阈值即使没有驱动电动机等，也能够实现最小功耗。并且即使当来自过电压传感器的过充电判定信号Vo变为导通状态时，电源装置也不判定高电压电池是否过充电（S240-S310）。因此，在充电之后，防止在系统启动时将高压电池错误地确定为过充电。版权所有（C）2012，JPO＆INPIT
