The message content and message cycle of the vehicle side can all be set, and various message conditions of the car can be simulated. 3. The host computer uses the USB interface for direct control, which eliminates the trouble of wiring and adapters compared with 485 and 232. 4. Real-time message output and translation during communication, and real-time saving function. It is equivalent to having the function of a CAN box, which is convenient for direct use and fault analysis of various relevant personnel. 5. The average cycle, number of transmissions, maximum cycle, and minimum cycle statistics of various messages. The Gantt waveform output of the message makes the fault analysis of the charging pile more intuitive and comprehensive. 6. Communication consistency test of the charging pile, and has the function of outputting analysis reports. 7. With battery voltage simulation, it can simulate the battery positive connection, reverse connection, and no connection test. 8. Multi-level R4 resistance setting, which can test the critical gun withdrawal state and the complete gun withdrawal state. 9. Multi-level DC+, DC- leakage resistance simulation, which can perform balanced and unbalanced leakage tests on the insulation inspection of the charging pile. 10. With a level 1 energy meter, it can display the output voltage, current, power of the charging pile in real time, count the charging power, and synchronize the data to the BCS message. 11. SOC automatically increases, and the charging time can be set to achieve the automatic aging test function. 12. Partial interoperability test, insulation fault test, gun withdrawal test, battery reverse connection, no connection test, etc. 13. It adopts a trolley box structure design, which is easy to carry out and can be used for daily inspection and maintenance of charging stations. Reference standards: GB/T 27930-2015 "Communication protocol between non-onboard conductive charger and battery management system of electric vehicles" GBT 27930-2011 "Communication protocol between non-onboard conductive charger and battery management system of electric vehicles" SAE-J1939-21 "Data link layer" GBT 20234-2015 "Connection device for conductive charging of electric vehicles" GBT 34658-2017 "Communication protocol consistency test between non-onboard conductive charger and battery management system of electric vehicles" GBT 34657-2017 "Electric vehicle conductive charging interoperability test specification" Hardware Description 1: VCD-BG01 is equipped with a DC1000V/250A DC gun holder and a DC+, DC- quick terminals with a maximum current of 300A, so that users can connect external loads to test charging piles of various powers. At the same time, in order to facilitate users to connect external oscilloscopes, multimeters and other instruments, all the remaining 7-hole terminals of the gun holder are led out. 2: It uses a 7-inch touch screen for operation. The main page contains various commonly used settings and electricity meter information such as required voltage and required current. 3: Classification display of each message, real-time display of each message data of the charging pile. It can simulate all fault codes of BMS messages and analyze the timeout fault of charging pile messages. Each message period can be set. 4、It has battery detection test, insulation leakage test, gun draw test, etc. It covers a variety of options and can simulate various situations. 5： Data preservation and factory default restoration. Data preservation without loss during power failure saves the trouble of resetting each time the power is turned on. Software Description 1: View and set the content of the communication message. You can set all vehicle-side BMS communication messages except BEM. And update the display in real time. Users do not need to worry about setting the wrong parameters. The software will identify the wrong parameters and remind you. 2. Comprehensive CAN message analysis function, with message waveform, CAN box receiving and sending function, Chinese translation of messages, and real-time storage of CAN message data. The number of times each message is sent, the current interval time, the minimum interval time, the maximum interval time, and the average interval time are all counted and displayed in real time. 3. Communication consistency test, interoperability related test, charging pile aging test, etc. Each communication consistency test has the function of outputting analysis reports. The test conclusion is shown as follows: Test number: DN.2005 Precondition: 1) The test system receives CML message and CTS message (optional).
