Service Plug
A removable safety connector that isolates high-voltage batteries during service.
The service plug disconnects HV battery circuits to ensure technician safety during repairs. It's usually bright orange and includes a resistor to discharge residual energy. Removing the plug disables the powertrain system. Technicians must follow manufacturer safety protocols when handling it. Reinstalling securely after service restores system integrity. It's a crucial component for EV maintenance safety.
