Recently, EV WPT has undergone some major breakthroughs. In May 2020, Mainland China officially released GB/T 38775; July of the same year saw the announcement of the UL 2750 Outline of Investigation for Wireless Power Transfer Equipment for Electric Vehicles; and it is estimated that in 2021, there will be EVs with standard WPT systems on the market. In terms of technology, Japanese automakers and the American Oak Ridge National Laboratory (ORNL) have successively announced bidirectional WPT technology. In addition to traditional G2V (Grid to Vehicle) charging, the bidirectional charging device allows the EV to feed back power to the grid and become a mobile giant battery. This V2G (Vehicle to Grid) function is in line with the development and application of smart microgrid storage balance grid.

With the Chroma 8000 Automated Test System as the core, Chroma's EV WPT test system can configure a complete series of AC and DC power supplies and electronic loads. The test system covers the power requirements of WPT such as SAE J2954 and GB/T 38775. It can test the power effect of the wireless charger's inlet, the stability and accuracy of the outlet, as well as the voltage and current limit protections. Equipped with a 2-in-1 power grid simulator and battery simulator, the EV WPT test system can also achieve G2V, V2G, as well as V2L (Vehicle to Load) WPT bidirectional charging and discharging simulation tests.
