<P>PROBLEM TO BE SOLVED: To provide a battery system that inexpensively implements a constant current value flowing through each series cell group. <P>SOLUTION: A power system (100) includes a plurality of power units (4) each for supplying power from a battery pack (1) to an electric motor (3) via a power supply line (2). Especially, a power supply line (12) is disposed with one end connected to a junction (11) and the other end connected to a common potential line (13) connected to an accessory (15). A rectifier (16) is inserted in series in the power supply line (12) to limit the direction of current to a direction from the junction (11) to the common potential line (13). <P>COPYRIGHT: (C)2012,JPO&INPIT |
