Abstract

The invention provides an electric charging system and an electric vehicle which properly output warnings of welding faults of a relay. The electric vehicle includes a power receiving connector which is connected to a battery via a relay, and an electric charger includes a power supply connector which 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 (step 9) to inform an operator the risk. Then the connection state is detected between the connectors (step 10). 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 (step 11). 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.

Description

technical field [0001] The present invention relates to a charging system and an electric vehicle, and in particular, to a technique for warning of welding failure of a relay. Background technique [0002] In recent years, electric vehicles provided with an electric motor as a power source have been developed. When charging a power storage device such as a battery mounted on an electric vehicle, a power supply terminal extended from an external charger is connected to a power receiving terminal of the electric vehicle. In addition, for a hybrid electric vehicle equipped with an engine and an electric motor as a power source, a so-called plug-in electric vehicle in which an electric storage device is charged by an external charger has also been developed. [0003] Since the terminal voltage of the power storage device is applied to the power receiving connector installed in such an electric vehicle, it is necessary to ensure safety when the power receiving connector is expos...
