A battery replacement assisting system includes a server configured to determine, from a plurality of battery packs including a recycled battery pack, a battery pack serving as a replacement candidate for a battery pack mounted on the vehicle. The server is configured to: acquire a state of deterioration of the battery pack; select a battery pack having a life longer than a period until the planned time from the plurality of battery packs by calculating a distance (life) in which the vehicle can travel until a capacity maintenance ratio of the battery pack reaches a threshold value (Qth); and determine the replacement candidate using a result of the selection and the expense information. The battery replacement assisting system further includes a display configured to notify the user of the replacement candidate determined by the server and the expense information of the replacement candidate.

A capacity restoration system restores a capacity of a battery pack including lithium ion secondary batteries and mounted on a vehicle. The capacity restoration system includes a capacity restoration device, a communication device, and a server. The capacity restoration device is configured to perform a restoration process to restore a capacity of the battery pack by maintaining a SOC of the battery pack to be equal to or less than a reference value. The communication device is configured to acquire restoration data. The restoration data includes: the reference value for the SOC, the reference value being used for the restoration process; and a capacity restoration ratio attained by the restoration process. The server is configured to use the restoration data to calculate the reference value used for the restoration process for a target vehicle.

A controller performs first control to fourth control whenever the voltage of a cell reaches a specified voltage during discharging. The first control is to stop the discharging. The second control is to close a relay connected, in parallel, to a cell having a voltage having reached the specified voltage. The third control is to measure AC impedance in a state in which relays connected, in parallel, to respective corresponding cells having voltages having reached the specified voltage are all closed. The fourth control is to resume discharging cells having voltages higher than the specified voltage. The controller diagnoses whether the cell having the voltage having reached the specified voltage is abnormal, by comparing (i) AC impedance when the cell having the voltage having reached the specified voltage is included with (ii) AC impedance when the cell having the voltage having reached the specified voltage is excluded.

A vehicle identifying unit obtains an identification number of a vehicle from the vehicle. A first evaluation unit evaluates a degradation state of a power storage device based on the use history of the power storage device obtained from the vehicle, using data analyzed beforehand concerning the relation between the use history and the degradation state of the power storage device. A second evaluation unit evaluates a degradation state of the power storage device using data collected when the power storage device of the vehicle is charged from a power station or when power is fed from the vehicle to the power station. A degradation determining unit determines the degradation state of the power storage device based on the degradation states evaluated by the first and second evaluation units.
