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.
Solution details
Test requirements:
The safe dielectric strength value can be flexibly adjusted according to the requirements of different products.
Wiring harness test bench tests:
- Interruption detection
- Testing for open circuits and line breaks
- Miswiring test
- Detection of incorrect connections or line assignments
- Recognition of correct connection assembly
- Checking whether connections and terminals are fully and correctly installed
- Leakage test
- Air tightness testing of cable harness components
- Instructions for removing the cable after successful testing
- Display of a prompt to remove the wiring harness after passing the test
