Interlock

The electrical interlock is one of the most important safety features on modern electric drive vehicles. The interlock separates the high voltage battery from the rest of the vehicle when a high voltage cable has been incorrectly disconnected and understanding this concept will help the technician diagnose faults or may even save some one's life.
