ELECTRIC CHARGING SYSTEM AND ELECTRIC VEHICLE
First Claim
1. An electric charging system in which an electric vehicle is provided with a power receiving connector that connected to an electric storage device via a relay unit, and the power receiving connector is connected to a power supply connector of an electric charger, whereby charging power is supplied to the electric storage device from the electric charger, the electric charging system comprising:
- a information storage unit that stores information on a weld failure that occurs at the relay unit;
a connection detection unit that detects a connection state between the power receiving connector and the power supply connector; and
a warning unit that issues an warning when the power receiving connector is not connected to the power supply connector under a state where a weld failure occurs at the relay unit and stops issuing a warning when the power receiving connector is connected to the power supply connector under a state where a weld failure occurs at the relay unit.

Abstract
An electric vehicle includes a power receiving connector that is connected to a battery via a relay, and an electric charger includes a power supply connector that is connected to the power receiving connector. When a high voltage is applied to the power receiving connector due to a weld failure of the relay, a warning lamp flashes to notify an operator of the risk. Then the connection state is detected between the connectors. When the connectors are not connected to each other, a warning buzzer issues a warning sound. When the connectors are connected to each other, the warning buzzer is turned off. The power receiving connector is covered by the power supply connector in this manner, the operator is unlikely come in contact with the power receiving connector, and thus the output of a warning sound from the warning buzzer is stopped.
