High-performance battery simulator PDL

programmablehigh-accuracycharge/discharge test

The programmable DC load unit can simulate the voltage and current power characteristics of the electric vehicle's power battery, and carries out the load test on the DC charging pile. It can also simulate the characteristics of auxiliary battery or DC motor to test on-board DC-DC. The working mode can be constant voltage, constant current, constant power and constant resistance. It adopts closed-loop control with high precision. Switching devices use high-speed IGBT devices to achieve micro-second (us) level switching; High speed and stepless regulation in constant voltage and constant current modes. Nickel-chromium alloy material resistance was used, which is light in weight, high in working temperature and free from red heat; Modular design, 19-inch 5U high chassis. Host/slave integrated design. Rugged case adapt harsh environment for site using. Application: Off-board Charger Auto-test Off-board charger (DC charging pile): The special power supply device installed outside of the EV and convert AC power into DC to charge EV traction battery with conductive method.
