    The Importance of Relays in Electric Vehicle Charging Systems
    In an electric vehicle charging system, relays serve as the interface between the charging equipment and the vehicle itself. A relay is an electrically operated switch that opens and closes circuits in response to electrical signals. When it comes to EVs, these relays are responsible for managing high-voltage DC and AC currents, ensuring that the right amount of power is delivered to the vehicle’s battery safely.
    Relays are also tasked with ensuring that charging stations operate within safe parameters by preventing overloading, overvoltage, and short circuits, which could otherwise damage the vehicle or cause safety hazards. Given the high stakes involved, ensuring the reliability and safety of these relays is paramount.
