Chroma, a test and measurement instrumentation company, has released a new software platform that has multi-threaded testing functionality for electric vehicle supply equipment (EVSE) test solutions.
PowerPro 5 can simulate up to four vehicles having identical or different communication protocols such as GB/T, CCS or CHAdeMO. The software controls the EVSE to serve multiple connectors at once based on the given test circumstances and can simulate plugging in at different times in order to comprehensively test the equipment’s power sharing capability. This cuts testing time by 40% compared to single-coupler testing, according to the company, increasing test capacity.
Simulating single and multiple vehicle signals allows four-coupler power distribution testing and communication protocol verification.
