Abstract: A battery disconnect unit including a housing, an electronic relay module installed on a charge/discharge line of a battery within the housing and including electronic switch devices capable of a switching operation of selectively blocking the flow of a current in the charge/discharge line, a heat dissipation cover provided with a structure surrounding at least a portion of the electronic relay module and formed of a material capable of heat exchange with the electronic relay module, and a cooling plate disposed in contact with the heat dissipation cover and provided to allow a refrigerant to flow in the cooling plate.

Abstract: The present invention relates to a system for charging an electric vehicle and to a method for charging the electric vehicle. A charging stand which supplies electric power for charging to the electric vehicle performs user authentication or vehicle authentication for the electric vehicle to be charged, so as to prevent unauthorized charging or theft and thus enable the electric vehicle to be stably charged. In addition, a connection circuit is used as a connection cable or a connector for charging, which interconnects the vehicle and a charging side by means of a single line to enable both the vehicle and the charging side to recognize the interconnection, thus simplifying the configuration of the circuit for enabling the vehicle and the charging side to recognize the interconnection, and enabling both the vehicle and the charging side to easily recognize whether or not they are interconnected.
