The purpose is to provide an electric vehicle charging device capable of preventing arc discharge when disconnecting a power supply connector and a vehicle-side connector. An electric vehicle charging device provided with: a power supply connector () for supplying electrical energy from outside the vehicle; a vehicle-side connector () for connecting to the power supply connector () and positioned in the vehicle; a spring () for generating repulsive force in the direction in which the power supply connector () and the vehicle-side connector () separate; and an engaging part () for detecting the disconnection of the power supply connector () and the vehicle-side connector (); wherein the spring () generates repulsive force in the direction in which the power supply connector () and the vehicle-side connector () separate when the engaging part () detects that the power supply connector () and the vehicle-side connector () have disconnected.

Electric vehicle charging device

Provided is an in-vehicle charger capable of reliably obtaining charging control parameters prior to charging and capable of safe charging. In this charger, a charging unit () charges a battery () in accordance with the charging control parameters. A storage unit () stores a table in which a plurality of areas on a map and the charging control parameters are made to correspond to each other. A position information receiving unit () obtains position indicating the current position of a vehicle (). A control unit () refers to the table on the basis of the position information and sets the charging control parameters made to correspond to an area including the current position when a charging cable () is not connected.

In-vehicle charger

A risk-degree setting unit () sets the degree of risk for the case where an inverter () performs conversion processing (inverter risk degree), and sets the degree of risk for the case where a storage battery () stores electrical energy (storage battery risk degree). A final output destination determination unit (), based on the degrees of risk set by the risk-degree setting unit (), determines the final output destination of electrical energy output from an electric motor (), and controls the turning ON or OFF of a relay (). The final output destination determination unit () turns the relay () ON when the storage battery () is determined as the final output destination of the electrical energy output from the electric motor (), and turns the relay () OFF when the inverter () is determined as the final output destination of the electrical energy output from the electric motor ().
