Document Type and Number:
Japanese Patent JP6414580
Kind Code:
B2
Abstract:
A capacity restoration system (9) 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 (40), a communication device (340), and a server (300). The capacity restoration device (40) is configured to perform a restoration process to restore a capacity of the battery pack (10) by maintaining a SOC of the battery pack (10) to be equal to or less than a reference value (X2). The communication device (340) is configured to acquire restoration data (PI, P2). The restoration data includes: the reference value (X2) for the SOC, the reference value (X2) being used for the restoration process; and a capacity restoration ratio (R) attained by the restoration process. The server (300) is configured to use the restoration data (P1, P2) to calculate the reference value (X2) used for the restoration process for a target vehicle (1).
