Which safety features are provided by electric vehicle supply equipment (EVSE)?

• A. A continuously energized output
• B. Emergency shut-off switch
• C. Hardware fault detection
• D. GFCI protection

Answer: (D)

Electric Vehicle Supply Equipment (EVSE) plays a critical role in ensuring the safety of electric vehicle charging operations. Ground Fault Circuit Interrupter (GFCI) protection is specifically designed to monitor the electrical current flowing through the circuit. If it detects an imbalance, which could be an indication of a ground fault (like current leaking through a person), the GFCI quickly disconnects the power to prevent potential electric shock or fire hazards. GFCI protection is particularly vital in environments where water exposure is possible, such as exterior charging stations or where vehicles may be washed. By cutting off the electricity during a fault condition, the GFCI helps to ensure that the charging process remains safe for users and minimizes the risk of electrical accidents. While other safety features like hardware fault detection and emergency shut-off switches are important as well, GFCI protection directly addresses electrical shock risks, making it a fundamental safety component of EVSE.
