EVSE must include a(n) what to prevent the charging connector from being accidentally energized before it is connected to the vehicle?

The inclusion of an interlock in the Electric Vehicle Supply Equipment (EVSE) is crucial for safety during the charging process. An interlock mechanism ensures that the charging connector cannot be energized until it is securely connected to the vehicle. This design feature prevents the risk of electric shock or electrical arcing that could occur if the connector were to be energized while not properly connected.

Interlocks can function in various ways, such as mechanically locking the connector in place or using electrical signals to confirm a secure connection before enabling the flow of electricity. This is vital for both user safety and to protect the vehicle's electrical system from potential damage.

Other options lack this specific function. An emergency shutoff is focused on cutting power in case of an emergency, a safety lock could refer to various physical locking mechanisms, and a fuse serves to protect the circuit from overloads rather than managing the connection status between the charger and the vehicle.
