<p>PROBLEM TO BE SOLVED: To make exchangeable a battery before the end of its battery life by accurately determining battery life. SOLUTION: In this life determining method of a secondary battery for motor vehicle, a current flowing in the battery, a battery temperature, and a residual capacity of the battery are detected at a prescribed sampling cycle, and a parameter value is specified from a detected detection value, and the specified parameter value is operated, and the battery life is determining from the operated total parameter value.</p> |
