Which safety feature is crucial for preventing electrocution during EV charging?

• A. Ground Fault Circuit Interrupter
• B. Surge Protector
• C. Voltage Stabilizer
• D. Cooling System

Answer: (A)

The Ground Fault Circuit Interrupter (GFCI) is a critical safety feature for preventing electrocution during electric vehicle (EV) charging. This device is designed to monitor the electrical current flowing through the charging circuit. If it detects an imbalance between the outgoing and incoming current—such as when electrical current leaks to the ground—it immediately interrupts the circuit. This rapid shutdown can greatly reduce the risk of electric shock, protecting individuals who may come into contact with the charging equipment. The importance of a GFCI increases when charging EVs outdoors or in potentially wet environments where the risk of moisture contact with electrical components is higher, making it particularly susceptible to faults that could lead to serious injury or electrocution. While other devices like surge protectors contribute to the overall safety of the electrical system by protecting against voltage spikes, they do not specifically guard against ground faults that could cause shock. Similarly, voltage stabilizers and cooling systems serve different functions, such as maintaining consistent voltage levels and preventing overheating, respectively, but do not provide the immediate protection against electrocution that a GFCI does.
