Automated test systems for electric and hybrid electric vehicles
Chroma

As power conversion and battery technologies advance in the automotive industry, Chroma has been actively working to improve electric vehicle (EV) testing performance and cost by developing flexible automated power conversion test platforms and regenerative battery test systems.

Chroma’s automated test systems for electric and hybrid electric vehicles consist of standard test platforms that are combined into one expandable test system that can test most power components in an EV’s power system. Compared with specialized test equipment developed for a single EV model or application, Chroma’s systems provide greater flexibility.

The Chroma 8000 Automated Test System meets the requirements of SAE J1772 and GB/T 18487.1 for full function testing of AC Level 1 and Level 2 electric vehicle supply equipment (EVSE). It is built to address the testing needs of EVs and PHEVs from R&D to QA, production and field service. The system relies on Chroma’s extensive expertise in power electronics and enables seamless testing of EVSE, onboard chargers, DC-DC converters, motor drivers and other power electronics.

In addition to hardware flexibility, Chroma’s Automated Test System software includes a range of pre-written tests and the ability to create custom tests, giving users unlimited freedom in how their products are tested. The system also provides automatic data recording and statistical report creation, giving insight into opportunities for product improvement. This combination of configurable hardware and software enables manufacturers to reduce costs and ensure consistency through every phase of the product lifecycle.

Chroma’s lithium battery automated test solutions have been successfully adopted by several well-known automotive manufacturers, providing safe, real-time monitoring of the test process, reducing inspection time and significantly cutting production costs.

Chroma’s battery testers are regenerative, high-precision systems specifically designed for cell-, module- and pack-level battery testing. From charge/discharge to drive cycle simulation, Chroma’s accuracy in measurement ensures exact, reliable testing for battery incoming or outgoing inspections, as well as capacity, performance, production and qualification testing. The regenerative feature recycles energy sourced by the battery module either back to the channels in the system or back to the grid. The systems are flexible, making field upgrades possible.
