A DC Charging Station Relay is an electrical switch that controls the flow of direct current (DC) electricity between a charging station and an electric vehicle. Unlike alternating current (AC) charging stations, which rely on the vehicle’s onboard charger to convert AC to DC, DC charging stations directly supply DC power to the vehicle’s battery. The relay in these stations plays a crucial role in regulating the flow of electricity, ensuring that the charging process occurs safely and efficiently.

    Key Functions of a DC Charging Station Relay

    Control and Switching of Current One of the primary functions of a DC charging station relay is to control the flow of DC electricity to the vehicle’s battery. The relay acts as an intermediary between the charging station’s power supply and the vehicle, ensuring that electricity flows only when necessary. Once the charging is completed or if there is any interruption or malfunction, the relay disconnects the power to prevent further charging.
