DC charging pile test feedback aging system

● The vehicle-side message content and message cycle can all be set, which can simulate various vehicle message situations;

● The host computer uses USB interface for direct control, which eliminates the cumbersome wiring and adapters compared with 485 and 232;

● Real-time message output and translation during the communication process, and has a real-time saving function. It is equivalent to having the function of a CAN box, which facilitates direct use and fault analysis by various related personnel; statistics of the average cycle, number of transmissions, maximum cycle, and minimum cycle of various types of messages. Message Gantt waveform chart output makes fault analysis of charging piles more intuitive and comprehensive;

● Test the communication consistency of charging piles and have the function of outputting analysis reports;

● Equipped with battery voltage simulation, which can simulate the positive connection, reverse connection and no connection test of the battery;

● Built-in K5, K6 switch state simulation function, multi-level R4 resistance setting, can test critical gun withdrawal state, complete gun withdrawal state, resistance adjustment range 295Ω~2550Ω;

● Insulation module: It can meet the charger insulation, reverse connection test and non-connection test. The test voltage access range is 0~ 1000V, and the insulation resistance adjustment range is 22.9kΩ~300kΩ;

● It has a level 1 electric energy meter, which can display the output voltage, current, and power of the charging pile in real time, count the charging power, and can synchronize the data to the BCS message;

● Interoperability test, insulation failure test, gun pull test, battery reverse connection, no connection and other tests;

● It has terminals for pile end signal voltage, current, CC1, auxiliary power supply, abnormal synchronization signal, etc., and can be connected to other testing instruments for pile end signal testing and test inspection;

● Internally integrated battery voltage simulator, voltage range 0-1000V, used for charging pile startup timing test (optional);

● Charging pile socket: national standard, European standard, American standard, Japanese standard (optional);

● Energy saving and environmental protection: High-efficiency operation and ultra-low standby power consumption across the full load range, effectively reducing energy loss and achieving energy conservation and environmental protection;

● Energy-saving feedback: receives load energy; can be fed back to the grid, with a maximum conversion efficiency of more than 90%;

● Feedback load function settings: current, power, and time can be edited; jump, gradient, hold, and cycle can be set;

● Cooling method: forced air cooling.

● Optional measurement and verification functions: LAN, RS232, WIFI and other communication methods, built-in WIFI hotspot, remote wireless terminal. 0.05 level calibration test items: working error, indication error, payment amount error, clock indication error, which can complete the 0.05 level measurement calibration test function of JJG1149-2018.
