Wiring harnesses and connectors have already become a key element in conventional vehicles as they’ve incorporated more and more electronic features to be included in basic glass elevators, infotainment, and car safety systems. The industry is moving towards electrical and hybrid powered vehicles, and the increased connectivity and driving automation is expanding this trend to a new level.

What is wiring harness testing?

Wiring harnesses and connectors are responsible for connecting every component within a vehicle providing electric power and data transfer. In battery-power vehicles, these systems are split between the low voltage system and the high voltage system.

The latter are used to feed all the components involved in the electric power drive system. This includes the battery and its charging system, the electric motors, and all the related HV components (such as converters, OBC, BMS, thermal systems, etc.)

Why Is Wiring Harness Testing Important?

The performance, flexibility, and resistance of these wiring networks are critical for a vehicle’s functioning and need to be tested thoroughly. This ensures their reliability under different environmental conditions and operational stresses are therefore essential.
