Abstract

An electric automobile charging system wherein a center device, an electric automobile, and a charging device that charges a storage battery section in said electric automobile are connected by power lines. The center device acquires information of the amount of power generated and the amount of power used, decides on cutoff of the charging current or reduction of current to the storage battery section in the electric automobile, based on the acquired information, and communicates instructions for the cutoff of the charging current or current reduction that has been decided. The charging device receives the instructions from the center device and interrupts the charging current to the storage battery section in the electric automobile or reduces the current, based on the received instructions.
