Vehicle electrical and electronic equipment climate load test

The climate load test of road vehicle electrical and electronic equipment can determine the impact of electrical and electronic equipment in different climate environments, such as excessive humidity, which reduces the insulation strength of electrical equipment, humidity and mold, humid air is conducive to the growth of mold, humidity and metal corrosion, the impact of excessive temperature, etc.
Zhongke Testing Reliability Experiment Center has the capability of reliability performance testing of various road vehicle electrical and electronic equipment, and provides professional climate load testing services for road vehicle electrical and electronic equipment.
