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.
