The system is an automated test equipment for the integrated modules of on-board charger (OBC), DC-DC converter (DC-DC) and high-voltage power distribution unit (PDU) of new energy vehicles. The system is used to verify the function, performance and safety of the three-in-one assembly. It can be tested individually or together to ensure its reliable operation in the high-voltage system of the whole vehicle. It can significantly improve production efficiency, reduce labor costs, and ensure the high quality and consistency of products before leaving the factory.

1. Charging performance test: Test the charging power, charging efficiency, charging voltage and current stability of the charger to ensure that it can charge the power battery normally under different charging conditions, such as AC slow charging and DC fast charging;

2. DC/DC conversion performance test: Detect the conversion efficiency, output voltage stability, ripple coefficient and other parameters of the DC/DC converter to convert high-voltage DC into low-voltage DC to ensure that it can provide a stable power supply for the vehicle-mounted low-voltage electrical system;

3. High-voltage power distribution function test: Verify the distribution and management functions of the high-voltage distribution box for high-voltage power supply, including the on-off control, overcurrent protection, short-circuit protection and other functions of each high-voltage load circuit to ensure the safe operation of the high-voltage electrical system;

4. Communication function test: Check whether the communication function between the three-in-one charging and distribution assembly and other electronic equipment such as the vehicle control system and battery management system is normal to ensure the accuracy and timeliness of data transmission;

5. Protection function test: Test various protection functions of the charging and distribution assembly, such as overvoltage protection, overcurrent protection, overheating protection, undervoltage protection, etc., to verify the accuracy of the protection threshold and the timeliness of the protection action.
