摘要

Charging that conforms to the specifications of both a charger and a battery to be charged can be more smoothly started.Before starting to charge an in-vehicle battery (203), the control unit (205) of an electric vehicle (200) and the control unit (106) of a charger (100) exchange battery information describing a battery performance and charger information describing a charger performance via communication lines (2012, 1012) and determine a charging condition that satisfies the specifications of both the in-vehicle battery (203) and the charger (100). The control unit (205) of the electric vehicle (200) supplies a charging current specification value that satisfies this charging condition via the communication lines (2012, 1012) to the control unit (106) of the charger (100). The control unit (106) of the charger (100) determines, from this charging condition, the supply and stop timings of the charging power corresponding to the charging current specification value supplied from the electric vehicle (200).
