Wireless Future – Newly Launched Chroma Electric Vehicle Wireless Power Transfer ATS

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.

The AERO Team at Beihang University: The Movement Towards the Unmanned Electric Vehicle

By Chroma Electronics

During the 8th anniversary of the Formula Student China (FSC) organization, Beihang University’s AERO team celebrated a decisive victory using their premiered retrofitted electric car at the first annual Formula Student Autonomous China (FSAC) competition. In recent years, the direction of electric vehicles has been trending towards a new technological state of autonomy, or “self-driving.” Beihang University is one of the few top universities in the FSAC to participate in, not only both traditional fossil-fuel and electric vehicle competitions, but now also the “unmanned” vehicle movement. Thus, the team required a higher level of technology to back up its demands; the hardware and software needed to be functionally integrated with high complexity to ensure stable operation of electronic product. Chroma Electronics provided the university’s AERO team with professional testing equipment and experiences to assist in achieving its electronic vehicle development plans and to improve the overall unmanned vehicle campaign.

The development of electric vehicles is one of China’s most important growth strategies, driving both the battery and energy storage industries.
Chroma’s automatic test systems (ATS) offer a wide range of AC/DC power supplies, electronic loads, and electrical safety tools to test EV/HEV related parts and equipment. Chroma’s multifunctional ATS can also be applied to power electronic devices like EVSEs, car chargers, DC/DC converters, motor drivers, etc. In addition, the system validates the high-voltage parts, checking the charging circuit and the potential equalization of the automotive body for electric cars. A powerful software testing tool is provided to help integrate the DC power supplies and electronic loads in order to perform necessary tests on the battery storage system.

Furthermore, the Formula SAE Electric Racecar competition, hosted by SAE International, nurtures future talents in China’s new energy automotive industry. Chroma Electronics has been a part of China’s new energy industry for years while supporting the social responsibility of shouldering numerous formula student electric team endeavors. Chroma’s multiple test solutions have received recognition from China’s energy industry and academia as well by helping customers identify the potential risks during the design verification process. Chroma’s solutions correct these product problems in order to accelerate the R&D process and to propel new business opportunities.
