Abstract: 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.

A switching speed at which when each of the switching elements is turned on or turned off is controlled in accordance with the operation mode. Specifically, the switching speed in the second operation mode is higher than the switching speed in the first operation mode.

Abstract: An MPU performs a degradation diagnosis based on an open circuit voltage characteristic of a rechargeable lithium ion battery indicating how the battery varies in open circuit voltage as the battery varies in capacity to obtain a capacity ratio of a positive electrode, a capacity ratio of a negative electrode, and a deviated capacity of the battery. The MPU applies the capacity ratio of the positive electrode and the capacity ratio of the negative electrode to a predetermined map for degradation attributed to wear to estimate a deviated capacity resulting from degradation attributed to wear and separates the deviated capacity into the deviated capacity resulting from degradation attributed to wear and a deviated capacity resulting from deposition of lithium. The MPU uses at least the deviated capacity resulting from deposition of lithium to determine whether a rechargeable lithium ion battery subject to determination of degradation is reusable and/or recyclable.
