Abstract

An electric power information control unit compares electric power value information relating to a specific electric power amount of an electric power amount of a first storage battery and electric power value information relating to the specific electric power amount of the electric power amount of the second storage battery. When there are electric power information in which the electric power value information relating to the specific electric power amount are different from each other in the first and second storage batteries, the electric power information control unit swaps and stores the electric power value information in the first electric power information storing unit and the second electric power information storing unit.

Claims
