As electric vehicles (EVs) continue to surge in popularity worldwide, EVSE (EV supply equipment) infrastructure is expanding rapidly. At present, one of the industry's critical challenges is defining standards to ensure that these outdoor charging stations provide both safe charging and accurate billing. Charging stations are typically installed for an extended period, and transporting them back to laboratories for testing and measurement can be impractical and costly. To address this, Chroma has developed a mobile testing solution that has already been adopted by multiple leading laboratories and charging station manufacturers.

For the testing needs of energy metering, Chroma offers the 8000 AC/DC EVSE Automated Test System (ATS). Beyond stationary test systems suitable for standard certification laboratories, Chroma also provides customized, mobile testing solutions tailored for the periodic test and inspection of outdoor charging stations.

Key features of this automated test system include:

• Customizable hardware (physical dimensions) and software user interfaces based on client needs.
• 2-in-1 AC/DC charging simulation functionality, supporting a maximum power/voltage of 18kW/1200V.
• Compatible with AC/DC charging interfaces such as SAE J1772, CCS1, CCS2, CHAdeMO, TPC (NACS), and more.
• Compliant with high-precision voltage/current accuracy specifications: <0.1%.
