| Abstract | PROBLEM TO BE SOLVED: To provide a more accurate inspection method.SOLUTION: In an acceptance inspection method for determining whether a secondary battery is acceptable or not based on a terminal voltage difference V between terminal voltage V1 during delivery inspection in the manufacturing factory of the secondary battery, and terminal voltage V2 during acceptance inspection in a battery pack manufacturing factory, a voltage drop VA due to micro internal short-circuit is set while taking account of the temperature influence in a transportation period or during transportation. A battery indicating a V value smaller than the VA is determined unacceptable, thereby performing inspection with higher accuracy and maximizing the reliability of a battery pack. |
