As the future of power electronics continues to grow, electric vehicle (EV) technology advances as well redefining the meaning of EV convenience and safety with the new feature: “wireless charging.” Wireless charging brings significant changes to the EV industry by removing the need for charge connectors completely thus preventing connector wear-out and electric shock hazards. Through successful testing and measurements of key EV components, Chroma ATE, a world leading electronics testing company, launched its first EV Wireless Power Transfer ATS.
In May 2016, the Society of Automotive Engineers (SAE) announced a wireless charging standard, the SAE J2954, set up by several internationally renowned car manufacturers and tier 1 suppliers. China held extensive and rigorous tests on EV wireless charging products in order to further research the new technology and lay the foundation for GB/T standards; over 20 domestic companies participated in the testing. Chroma had developed complete AC sources, DC load product lines, and automated test systems encompassing the new standards need for a minimal power requirement of 3.7KW~22KW. This allowed for new levels of power effective tests on input, stability accuracy measurements on output, and limit voltage and current protections for wireless charging. In addition, the new development successfully conducted offset angles simulation and efficient measurement of X, Y, Z, Ψ, Ɵ, Φ six axes when used with the EV Wireless Power Transfer ATS and in conjunction with the new standards as well.
Chroma's EV Wireless Power Transfer ATS has been adopted by the China Automotive Technology & Research Center (CATARC), China Electric Power Research Institute, and Experiment & Verification Center of State Grid Electric Power Research Institute (NARI) laboratories, as well as several international car factories. Testing inquiries expanded internationally to mainstream Chinese, Japanese, and European car manufacturers.
