<P>PROBLEM TO BE SOLVED: To update battery information used for estimating a battery charge sate according to a deterioration degree of a battery after a change when changing batteries to be mounted in a vehicle. <P>SOLUTION: A vehicle 2 obtains a deterioration degree of a battery 13 on the basis of a detection result of a battery monitoring unit 14, and updates battery information stored in a memory 16 on the basis of the obtained deterioration degree of the battery. When a battery pack 8 is changed, the vehicle 2 causes battery data in which a battery ID of the battery pack 8 before the change and the battery information are associated with each other to be transmitted to a server 7, as well as request data indicating a battery ID of a battery pack 8 after the change to be transmitted to the server 7. The server 7 updates battery information of battery data in a memory 26 corresponding to the battery ID indicated by the received battery data to the battery information indicated by the battery data transmitted from the vehicle 2 and extracts battery data corresponding to the battery ID indicated by the received request data from the memory 26 so as to transmit it to the vehicle 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
