Chroma's New Software Platform Boosts Multi-Coupler EVSE Test Efficiency by 40%
With the rapid development of the electric vehicle (EV) market, the charging power and current of electric vehicle supply equipment (EVSE) is also continuously increasing, resulting in shorter charging times and improved user experience. EVSE development is now moving towards designs that include multiple charging connectors to increase the equipment's flexibility and usage. Such multi-coupler EVSE also contains multiple power modules that need to be allocated according to the varying power requirements of different vehicles, and dynamically adjusted as these requirements change. A single charging system even includes different charging standards to be able to adapt to different EV types. These new features of EVSE pose challenges for how to quickly and completely test and verify them during production.
Multi-threaded test function reduces testing time by 40%
Chroma’s compatibility and functional testing systems for EVSE have already been adopted by a great variety of domestic and foreign testing labs. Many EVSE manufacturers also use our solutions for end-of-line testing in their factories. Besides testing the charging process and safety mechanisms, one of the most important test items for multi-coupler EVSE products is power sharing (load management) testing. Chroma's EVSE test solution, integrated with our new PowerPro 5 software platform, is now equipped with multi-threaded testing functionality and can simultaneously simulate up to four vehicles with identical or different communication protocols, including GB/T, CCS, and CHAdeMO. The software allows the user to control the EVSE to output multiple connectors at the same time based on the specified test conditions, and can even simulate plugging in at different times to comprehensively test the equipment’s power sharing functionality. This enhances the realism of the test scenario and, compared to conventional single-coupler testing, reduces the overall testing time by up to 40%, significantly expanding test capacity. The Chroma PowerPro 5 software platform has already been successfully adopted by well-known EVSE suppliers. It can simultaneously simulate single and multiple vehicle signals to achieve four-coupler power distribution testing and communication protocol verification, effectively helping customers to ensure product quality and improve testing efficiency.
