Chroma ATE

BATTERY PACK POWER HIL TESTBED

Chroma ATE introduces the 8610 Battery Pack Power HIL Testbed, designed for comprehensive testing of electric vehicle (EV) battery systems and components. This versatile system supports testing of battery modules, battery management systems (BMS), and cooling/heating systems. Various hardware options are available for integration, such as a DC power supply, battery charge/ discharge system, digital meter, Hi-Pot tester, and short-circuit and overvoltage protection devices. Designed for development of battery modules and packs, the Chroma 8610 testbed features real-time hardware and software with an open architecture, enabling advanced testing capabilities. Besides basic test functions like importing of vehicle driving cycles, CAN signal monitoring, fault injection, insulation measurement, and EV supply equipment (EVSE) charging simulation, the testbed can also execute critical compound scenarios for real vehicles and composite operating conditions with high risk of failure (e.g. physical and communication signal errors during cyclic discharge). This feature-rich toolset greatly improves R&D efficiency by enabling in-depth tests on battery packs before entering the real car validation stage. The 8610 testbed integrates the highperformance Chroma 170X0 series of battery charge/discharge test systems. These systems provide dynamic simulation of battery pack discharging and regeneration under various driving conditions, enhancing testing reliability at the whole-vehicle level. During testing, the Chroma 170X0 will also feed the power output from the battery pack back to the grid to increase energy efficiency and save costs
