The application belongs to the technical field of brake system performance testing, and relates to an automatic testing system and method for HCU liquid path performance of a vehicle brake system. The system is arranged in a fully-closed safety cabinet, and comprises an upper computer, a servo cylinder pressure building, HCU control, dynamic cooling and a programmable load simulation unit. The system is cooperatively controlled through a CAN bus to realize accurate cooperation of pressure building, pressure maintenance, pressure reduction and valve body driving. The dynamic cooling system adjusts air cooling parameters according to load and time length to ensure stable coil temperature rise. The programmable load unit simulates working condition load by combining multiple steel cylinders. The testing method comprises the steps of preparation, parameter configuration, automatic exhaust, automatic testing, safety monitoring and report generation. Data is collected at high frequency throughout the process, and a PDF report with diagnostic suggestions is automatically analyzed and generated for archiving and storage in a three-level structure. The application realizes full-process automation, has high testing precision, high safety and traceable data, and can efficiently complete HCU liquid path performance detection.

The application relates to a portable power distribution terminal battery health inspection device and method. The device comprises: a battery inspection module for online parameter identification and health state evaluation of a backup battery of a power distribution terminal based on a battery equivalent circuit model; a debugging interface module integrated with an overcurrent protection circuit and an overvoltage suppression module; an analog circuit breaker module for simulating circuit breaker opening and closing operations, applying programmable load power to the power distribution terminal to verify the dynamic output performance of the battery; a state indication module for monitoring the connection state of the debugging interface module based on non-contact sensing technology and providing visual indication; and a communication detection module for listening to and analyzing communication data between the power distribution terminal and a superior master station, and verifying the quality of the communication link. The method can improve the accuracy, completeness and field operation efficiency of the power distribution terminal battery health state evaluation.
