DC Charging Pile Test Device

EVD1000V-30KW*2
The EVD1000V-30KW*2 DC charging pile test device consists of a load + national standard/European standard BMS simulation system, and uses a touch screen control method for simulated test operations (host computer remote control can also be used). It is mainly used for on-site installation, commissioning and function verification of DC charging pile products, and can also be used for online commissioning, offline testing, and function verification. The device truly simulates the charging process and various faults, avoiding the inconvenience of using a real electric vehicle as a test device, incomplete test content, inability to simulate real faults, inability to verify the auxiliary power system, time-consuming and labor-intensive charging and discharging of the vehicle's power battery, and shortened battery life due to frequent charging and discharging. At the same time, it can avoid damage to the test vehicle caused by charging pile failures.

Introduction to the host computer software:
1. Software registration:
After installing the test software, you need to obtain a registration code, and each machine has a unique code (the same registration code cannot be used on another computer). Therefore, users need to contact the manufacturer to obtain the registration code. After opening the software, find "Others", copy the computer feature code to the device manufacturer, and the device manufacturer will generate a registration code based on the computer feature code provided by the customer, which is used to copy and paste the registration code, and then click Register to complete the registration of the host computer software
2. Device connection:
Test equipment generally uses USB to serial communication. After the user connects the test equipment to the computer using a USB cable, the software will automatically search for the available computer COM port. The COM driver is identified as (USB-SERIAL CH340 (COM4)). Select the corresponding port and click the "Open Serial Port" button. After successfully connecting to the device, the software displays the communication data of each message, as shown in the figure below:
3. View and set the content of national standard communication messages
The software can be used with the test equipment to view all the message contents of the charging pile end, and can set all the vehicle-side BMS communication messages except BEM. And it is updated and displayed in real time. Users do not need to worry about setting the wrong parameters, the software will identify the wrong parameters and remind them.
The operation method is shown in the figure below: For example: remind the user that the maximum allowable voltage of the single power battery is set incorrectly. The operation of other similar messages is similar, and will not be shown one by one here.
4. CAN message receiving and sending function
This test software has the function of receiving and sending CAN extended frame messages, eliminating the trouble of users connecting an external CAN box to capture messages. All BMS messages have detailed Chinese translations, so users no longer need to waste time manually analyzing them one by one according to national standards, and they can be saved in real time as a table file together with the translation. When using the CAN message receiving and sending function, the CAN message capture function should be enabled first. The detailed operation method is shown in the figure below:
5. Communication consistency test
For the communication consistency test that complies with the national standard, users only need to check the corresponding test barcode and then click "Set" to take effect. The device configuration has the function of "output analysis report". The output analysis report example is shown in the following table:
Test number: DN.2005
Precondition:
1) The test system receives CML message and CTS message (optional).
Test steps:
1) The test system sends BRO message at a period of 250 ms, SPN2829≠0xAA.
Expected results:
1) Within 60 s from the first sending of CML message and CTS message (optional), the charger sends CML message at a period of 250 ms and CTS message at a period of 500 ms (optional).
2) After more than 60 s, the charger sends CEM message with SPN3923=01, and the message format, content and period meet the requirements of 9.5 and 10.5.2 in GB/T 27930-2015.
Test data:
1) Timeout: 60254 milliseconds, qualified

Receive BMS charging statistics message: Normal. The software automatic analysis results are not guaranteed to be 100% correct and are for reference only.
The communication consistency function is shown in the figure below
6. Message Statistics
The number of times each message is sent, the current interval, the minimum interval, the maximum interval, and the average interval are all counted and displayed in real time to help users eliminate errors in the sending cycle of each message. As shown in the figure below:
7. Message Gantt Chart
The convenience of Gantt chart is that time and progress are clear at a glance. Using Gantt chart for communication on BMS can often achieve unexpected results. If there is any way to allow engineers to locate where the communication failure occurred at a glance, Gantt chart can definitely do it. For example, for communication consistency testing, basically looking at the Gantt chart can make a judgment of almost everything. Of course, the basis of the message Gantt chart requires users to fully understand the national standard charging process. The following figure shows the software page of the message Gantt chart:
8. Interoperability related tests
The test equipment has fault simulation functions for test items such as battery detection, insulation detection, and gun removal detection.
1) Battery: can simulate positive connection, reverse connection, and no connection.
2) Leakage simulation: There are a total of 16 selection gears, covering balanced leakage, unbalanced leakage, abnormality, fault, and normal insulation detection test options.
3) R4 resistance: It is the CC1 gun insertion detection voltage, with critical value, no gun insertion, jump gun, and normal gun insertion test options.
4) Energy meter: Real-time statistics of charging pile output voltage, current, power, and accumulated energy, and the data can be synchronized to BCS.
5) SOC automatic increase: Users can use this function to achieve timed aging, because SOC selects automatic, and after reaching 100%, the test equipment will actively send BST to stop charging.
