HVIL Cable, a specialized cable used in electric and hybrid vehicles, connects the high voltage battery to the powertrain. It features an interlock mechanism that ensures safe disconnection of the battery during maintenance or servicing. The cable is engineered to withstand harsh environments, resist vibration and shock, and meet safety standards for high voltage applications.

The HVIL system is an essential safety feature in electric and hybrid vehicles that protects personnel during assembly, maintenance, servicing, and operation. Its primary function is to safeguard against high voltage components at all stages of a vehicle’s life cycle.

If a high voltage connection becomes loose, disconnected, or damaged while the vehicle is running, the HVIL system acts as a circuit breaker and alerts the driver or technician with fault codes. This helps prevent security-related issues and protects drivers and passengers in the event of an accident. The fault code also provides service technicians with valuable information about the nature of the problem, enabling them to address issues quickly.

Although different projects may have different designs for the low voltage monitoring circuit, the core purpose of the HVIL system remains the same: to ensure the safe operation of electric and hybrid vehicles.
