As the global automotive industry shifts towards electrification, the transformation is not limited to the cars themselves but also includes the charging infrastructure. Advancements in technology such as fast charging and high-capacity batteries present new challenges for testing and validation. To improve charging efficiency, increasing the voltage specifications of the busbars and batteries in electric vehicles (EVs) from 400V to 800V can bring several benefits, including reduced charging times, lower current passing through cables, and improved thermal management. However, charging station operators must also consider how to relieve drivers' range anxiety and provide more flexible power dispatch. For example, high-power DC fast charging stations above 250kW, combined with renewable energy such as solar and battery storage systems, can shorten charging time below 80% capacity and improve energy usage. In the face of future market demand for DC fast charging infrastructure, testing and validation during both early development and mass production stages are of critical importance.

The Chroma 8000 automated test system for EVSE, combined with the regenerative high-power Chroma 61800 grid simulator (paralleling up to 840kVA) and Chroma 17040 battery simulator (paralleling up to 600kW), integrates an EV emulator to provide an AC & DC EVSE test solution for various international charging standards (CCS, CHAdeMO, GB/T, ChaoJi, SAE, IEC). The 8000 ATS includes PLC and CAN communication data acquisition capability and protection mechanisms (such as automatic power switching, over-temperature, and over-current protection) to ensure reliability and safety for high-power testing. The Chroma 17040 has dual-mode functionality which allows the user to switch between battery simulator and battery charger/discharger mode via software, eliminating the need to buy extra equipment.

These test solutions have already been successfully adopted by internationally recognized certification bodies, including one of the most renowned EV and EVSE test laboratories based in Taiwan. The test lab meets international standards, can satisfy high-power demands, has great testing capacity, and covers the requirements of many different national safety standards. It specializes in professional testing services for electric vehicle charging systems, electric bicycles and scooters, and energy storage systems.

With nearly 40 years of experience in precision test and measurement instruments, Chroma ATE is a leader in automated test systems, specializing in various power and electrical testing applications. In response to the trend toward renewable energy, the company actively develops comprehensive solutions for electric vehicle, energy storage system, and fuel cell testing.
