CHARGING SYSTEM, CHARGER, MOTOR-DRIVEN VEHICLE AND METHOD FOR CHARGING BATTERY FOR THE MOTOR-DRIVEN VEHICLE

摘要

PROBLEM TO BE SOLVED: To more smoothly start charging in compliance with the specifications of both a charger and a battery to be charged.

SOLUTION: Before starting charging a vehicle-mounted battery 203, a control unit 205 of an electric vehicle 200 and a control unit 106 of the charger 100 exchange battery information indicating the performance of the battery and charger information indicating the performance of the charger via communication lines 2012, 1012, and determine charging conditions for satisfying both the specifications of the vehicle-mounted battery 203 and the charger 100. The control unit 205 of the electric vehicle 200 imparts a charging current command value satisfying the charging conditions to the control unit 106 of the charger 100 via the communication lines 2012, 1012, and the control unit 106 of the charger 100 determines timing of supply stop of charging power corresponding to the charging current command value to be imparted from the electric vehicle 200 on the basis of the charging conditions.
