The battery ECU 28 includes a RAM for storing a battery Bm in use for power supply at the last system operation stop. After the system stops an operation and then resumes the operation, the battery ECU selects a battery Bm+1 having a number next higher than that of the last used battery and executes control to close the relay SMRm+1 corresponding to the battery Bm+1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
