Testing And Certification
Make travel more reliable

Emc lab

Overview

It has the largest 10-meter semi-anechoic chamber in the country in the automotive field, equipped with a "3+1" axle chassis dynamometer system and a 12.5m turntable, which can meet the EMC testing needs of various models. In addition, it is the only electromagnetic compatibility laboratory at home and abroad that can simulate and detect road conditions of 18m vehicles. It has built a 3m semi-anechoic chamber with two systems of "hydrogen supply" and "dynamometer", and has product testing capabilities of "fuel cell engine system" and "electric drive system".
