Testing the continuity and voltage resistance of cable harnesses for New Energy Vehicles (NEV)
With the increasing prevalence of New Energy Vehicles (NEVs) , the demand for vehicle wiring harnesses is also continuously rising.
Before delivery, automotive wiring harnesses must undergo various tests, including:
- Electrical continuity test
- Detection of incorrect wiring
- Checking the correct assembly of connections
- Leakage test
The automotive wiring harness test bench from Tonghui Electronics enables all the aforementioned tests to be performed in a single system. This allows companies to reduce testing times and improve production efficiency.
