PROBLEM TO BE SOLVED: To reduce generated inductance by proximately disposing different polar terminals of a plurality of batteries, and connecting the different polar terminals via bus bars at the shortest distance so as to make currents flow in opposite directions. SOLUTION: Eight batteries 8 are arranged in each of two rows, thereby constituting a battery array 6. The batteries 8 are disposed proximately to each other in such a manner that the terminals 10 are brought into close contact with each other. The terminals 10 in close contact are connected to each other via bus bars 12. Such connection allows almost the same current to flow in the bus bars 12 adjacent to each other at the center in directions opposite to each other. Viewed in the cross section of the bus bar 12, two conductive bus bars 14, 15 are brought into close contact with each other via an insulating layer 16, and almost the same current flows in the bus bars 14, 15 in directions opposite to each other. Consequently, mutual inductance generated between the bus bars 14, 15 can reduce inductances generated in the bus bars 14, 15 according to the current flowing in the bus bars 14, 15. |
