HVIL, or high-voltage interlock loop, is a safety feature of hybrid and all-electric vehicles that protects people during the assembly, repair, maintenance and operation of a vehicle. The HVIL system is in place to protect those who may come into contact with high-voltage components at any stage of the electric vehicle lifecycle. HVIL acts as a circuit breaker that sends an alert or trouble code to the driver if a high-voltage connection becomes loose, disconnected or damaged during the vehicle’s operation. It also helps protect a vehicle’s driver and passengers in the event of an accident.
HVIL connector consists of a plug wrench with a card slot, a secondary lock with a guide slot and a high-voltage interlock microswitch to form an interlock mechanism. High-voltage interlock connectors include solutions for high-voltage, high-current, and signal connections for hybrid and electric vehicle high-voltage power harnesses and signal connections. It is available in a wide range of product options, 1 core to 3 cores, rated from 23A to 250A, touch resistant, single or multi-core shielded cables are available.
Application Scenarios
New energy vehicles, including electric and hybrid vehicles, use a variety of specialized connectors to meet their unique power and data communication needs. Some common types include: High Voltage Battery Connectors, Charging Connectors, High Voltage Wire Harnesses, etc.
