摘要

A first voltage control unit (50-1) includes a first PI control unit (54-1), a first switching unit (55-1) and a first subtraction unit (56-1). The first subtraction unit (56-1) subtracts an output of the first switching unit (55-1) from (a voltage value (Vb1))/(a target voltage (VR1)) that is a voltage feedforward compensation term. Similarly, a second voltage control unit (50-2) includes a second PI control unit (54-2), a second switching unit (55-2) and a second subtraction unit (56-2). A switching control unit (70) control first and second switching units (55-1 and 55-2) during temperature increase control to operate the PI control unit for the voltage control unit on a discharge side and to cut off an output of the PI control unit for the voltage control unit on a charge side.
