DEVICE AND METHOD FOR CALCULATING VALUE OF RECHARGEABLE BATTERY

摘要

A rechargeable battery is used with a plurality of battery cells restrained by a restraint member. After the rechargeable battery has the restraint member removed therefrom and is thus disassembled when the rechargeable battery is subsequently re-restrained by the restraint member and thus reused an internal resistance measurement unit measures the rechargeable battery's internal resistance based on battery data detected after the rechargeable battery is re-restrained. At least for the internal voltage, from a value thereof as measured after the battery is re-restrained an evaluation unit evaluates a value of the rechargeable battery that is reused.
