At the recent Automotive Testing Expo Europe, Xi’an ActionPower Electric Co, a manufacturer of power supplies and automated test equipment, showcased its new technologies addressing the test and verification needs of new-energy vehicles. This included the MIX Hybrid Power Supply, offering a high power density of 9.9kW per 3U, ultra-fast dynamic response and intelligent scalability.
According to the company, the system’s modular architecture enables flexible combinations of AC and DC input/output across six hybrid interface channels. This design supports a wide range of test topologies –including AC/AC, AC/DC, DC/AC and DC/DC – thanks to plug-and-play modules that can be quickly reconfigured to meet changing requirements.
With automatic module recognition and fast installation, engineers can easily set up test conditions for a variety of applications, including battery module and pack testing, onboard charger verification, motor control unit dynamic response tests, and real-time battery simulations for battery management system validation.
Another key innovation highlighted by ActionPower at the exhibition was its OBC/DC-DC ATE system, specifically designed to test the electrical characteristics of onboard chargers (OBC) and DC-DC converters in new energy vehicles.
The OBC/DC-DC ATE features a highly integrated, all-in-one architecture with a modular design that combines power supplies, loads, oscilloscopes and upper-computer control into a compact, space-saving platform. This setup not only simplifies wiring and reduces hardware costs but also improves system flexibility and testing efficiency.
Designed for both R&D and production environments, the system supports fully automated testing and offers broad compatibility. It can simulate a wide range of real-world operating conditions – including ripple and insulation faults, as well as V2V and V2L fault scenarios – covering up to 14 typical failure modes without the need for additional hardware simulation.
