EMC testing of in-vehicle equipment for EV/HV.

One-stop service for EMC testing, wireless testing, and high voltage electrical testing in compliance with various automotive manufacturer standards.

The Kashima EMC Testing Laboratory has constructed a next-generation mobility building equipped with two "EHV Chambers" capable of conducting EMC tests under real load environments that simulate driving conditions, starting operations in January 2020. With this equipment enhancement, EMC tests compliant with CISPR 25:2016 Ed.4 Annex I, ISO 11452-2 Ed.3 Clause 8, and GB/T 36282 will be possible. In addition to EMC testing, we have high-voltage equipment capable of testing LV 124, LV 123, and LV 148. We also offer wireless testing, allowing vehicle manufacturers to receive all required tests in a one-stop service. The next-generation mobility building will feature three anechoic chambers for vehicle use (including the two EHV Chambers) and three electrical testing rooms. The EHV Chambers are equipped with fixed dynamometers capable of reproducing real loads up to 125 N·m/12,000 rpm and a power absorption capacity of 170 kW. The dynamometer's gearbox has been redesigned to be placed outside the anechoic chamber, minimizing the size of metal objects located inside the chamber. This allows for measurements that are less affected by metal objects.

basic information

**Background of Next-Generation Mobility Building Construction** In the United States and Europe, exhaust emission regulations and fuel economy regulations have begun, and the electrification of vehicles continues to accelerate. As "electrification" and "connectivity" progress, automobiles have become running computers, and if electromagnetic noise emitted when onboard components operate causes electromagnetic interference between these components, it could lead to serious accidents. Therefore, the importance of EMC testing for onboard components is increasing. In October 2016, the international standard "CISPR 25:2016 Ed.4 Annex I" added evaluation methods for onboard components for EVs and HVs. This necessitated EMC testing under real load conditions simulating driving. Furthermore, similar tests were added to "ISO 11452-2 Ed.3 Clause 8" and "GB/T 36282-2018." To meet the growing domestic demand, the construction of the next-generation mobility building has been decided. **Kashima EMC Testing Laboratory** With a proven track record as an accredited testing laboratory for GM, Ford, JAGUAR LAND ROVER, MAZDA, and others, many experts provide specialized and meticulous services.
