CHARGING SYSTEM, CHARGER, ELECTRIC MOVABLE BODY, AND METHOD FOR CHARGING BATTERY FOR ELECTRIC MOVABLE BODY

摘要

Provided is a technique capable of more reliably starting and completing a charging control sequence even when a communication error occurs due to noise and capable of reliably opening a relay except for during charging.In addition to charging lines (1011, 2011) used for supplying charging power from a charger (100) to an electric vehicle (200) and communication lines (1012, 2012) used for exchanging a charging current specification value between the charger (100) and the electric vehicle (200), provided are driving power supply lines (1014, 2014) used for supplying driving power from a control-system power supply (107) to a relay (207) disposed between the charging line (2011) and an in-vehicle battery (203). By controlling the conduction patterns of the driving power supply line (2014), not only the relay (207) is opened or closed, but also the starting and completion signals of a charging control sequence are exchanged between the charger (100) and the electric vehicle (200).
