As electric vehicles continue evolving toward higher system integration, Chroma’s e-powertrain testing solution not only fully supports validation requirements for X-in-1 integrated systems but also delivers breakthrough capability for high-speed motor testing up to 30,000rpm, meeting the demanding requirements of next-generation e-powertrains for extreme rotational speed and high power density. The core advantages of this solution lie in multicomponent coordinated validation and HIL-based virtual-physical integration. The system enables synchronized control of multiple subsystems, including motors, OBCs and DC-DC converters, allowing precise emulation of energy flow management and dynamic loading conditions within a laboratory environment. Through seamless integration with vehicle dynamics simulation platforms, developers can reproduce extreme driving scenarios, energy management strategies and fault injection tests in the lab before prototype vehicles are available. This end-to-end virtual and physical integrated validation approach helps identify system-level risks early, significantly shortening the development cycle of high-power EVs while improving overall testing efficiency and product reliability.
