Conventional battery pack control devices have a problem that output power having a plurality of voltages cannot be supplied to a vehicle using a battery pack comprising a single type of battery cells. An assembled battery control device according to one embodiment of the present invention is provided with: a plurality of selection switches each connected to a lowermost voltage node and an uppermost voltage node of a plurality of battery cell groups set for a prescribed number of consecutive battery cells among the plurality of battery cells; a battery selection control unit that controls the ON/OFF of the plurality of selection switches so as to select a battery cell group including battery cells in which the characteristic deviation of the battery cells is larger than that of the other battery cells; and a low-voltage output unit that outputs low-voltage power having a lower voltage value than high-voltage power using the battery cell group selected by the battery selection control unit.

    在现有的电池组控制装置中,存在不能使用由单一类型的电池单元构成的电池组向车辆供给具有多种电压的输出电力的问题。本发明的电池组控制装置的一个方式具有:多个选择开关,所述多个选择开关与多个电池单元组的最下位电压节点和最上位电压节点分别连接,所述多个电池单元组是按照多个电池单元中的连续的规定个数的电池单元设定的;电池选择控制部,所述电池选择控制部对多个选择开关的接通与断开进行控制,以选择包括电池单元的特性偏差比其它电池单元大的电池单元的电池单元组;以及低压输出部,所述低压输出部使用由电池选择控制部选择出的所述电池单元组,来输出电压值比高压电力低的低压电力。
