Abstract
A vehicle charging system includes a charger configured to receive power form an external power source and a connector. The connector is configured to receive power from the charger and transmit the received power to a vehicle via a high-voltage cable. The cable is configured to connect the connector to a vehicle battery. Each of the charger and the connector includes a high voltage interlock loop (HVIL) configured to cause the charger to cease power transfer upon recognizing a predetermined voltage difference at a pair of ports of the HVIL.
