Zusammenfassung:	PROBLEM TO BE SOLVED: To precisely determine the deterioration of a storage battery for reflecting the startability of an engine using the pulsation of a voltage at the time of starting the engine. SOLUTION: In determining the deterioration of a storage battery for starting the engine for supplying power to a cell motor for starting the engine, the pulsation of a voltage of the storage battery generated at the time of driving the cell motor is monitored, and an initial voltage bottom value VS1 immediately after the cell motor is started, and a n-th voltage bottom value VSn after the first time are measured so as to compare VS1 and VSn for determining the deterioration of the storage battery. For example, deterioration is determined according to a difference ΔVn(=VSn-VS1) of VSn and VS1. COPYRIGHT: (C)2007,JPO&INPIT
