2. Test schematic diagram
The test schematic diagram is shown in the figure below. KM represents contactor, 13A represents AC socket, black square represents AC charging gun holder, control guide is control guide module, and M2 represents AC charging gun mode 2.
3. Test control principle
Device wiring schematic diagram, taking 10 products as an example, the back end is connected in series. The maximum number of tests is limited by the maximum allowable range of voltage drop. This device has 2 groups, each group of 10 products is tested online at the same time. Note: KMXA and KMXB are interlocked wiring and cannot be pulled in at the same time.
Brief introduction to the working principle of the electrical appliance:
Station 1, insert the product, KM contactor energizes, M2 product is powered on, and charging starts by controlling and guiding S2. If the product at station 1 is charged normally, KM1B is energized and KM1A is disconnected. If charging is not possible or there is no product, KM1A is energized and KM1B is disconnected, and electricity is directly transmitted to station 2.
Station 2, insert the product, KM contactor energizes, M2 product is powered on, and charging starts by controlling and guiding S2. If the product at station 2 is charged normally, KM2B is energized and KM2A is disconnected. If charging is not possible or there is no product, KM2A is energized and KM2B is disconnected, and electricity is directly transmitted to station 3.
And so on...
Station 12, insert the product, KM contactor energizes, M2 product is powered on, and charging starts by controlling and guiding S2. If the product at station 2 is charged normally, then KM12B is energized, KM12A is disconnected, and if charging is not possible or there is no product, KM12A is energized, KM12B is disconnected, and the power is directly transmitted to the load contactor.
The power meter measures the aging voltage and aging current of the product to be tested in turn, and stops aging if a defect is found.
4. Feedback load
The load adopts a feedback load, which is also called an energy feedback type electronic load. Compared with ordinary resistance loads, its working mode is to use power electronic conversion technology to recycle the output energy of the power supply to be tested on the premise of completing the test power experiment, and feed the electric energy back to the power grid without pollution, which saves energy and does not generate a lot of heat, avoiding the problem of rising ambient temperature in the test site.
5. Software
The system software has a one-button test, and all the test results can be recorded and queried. It has a QR code scanning function, which can trace the product test data. The operating table is designed according to ergonomics, and the equipment can perform self-test.
(1) The operating software uses a Chinese interface, which is simple and easy to learn.
(2) Computerized operation, all tests are completed at one time
(3) Can be connected to the MES system
(4) Scan code test
(5) Test data traceability
(6) Test data can be automatically saved as EXECL or TXT files

Instructions
1. Power connection, connect the power input to the external power supply AC220 V, connect the three-phase load power input to the three-phase power supply, press the "power main switch" on the side panel, turn on the "power switch" knob on the control panel, and the machine will start. If you want to select the three-phase mode test, turn on the "single-phase, three-phase switching" switch at the same time.
2. After turning on the computer, enter the standby interface. Open the desktop test software, enter the test interface, manually enter the material number, scan the station barcode, and then press Enter to save, as shown in Figure 5
Figure 5
3. After installing the sample, click the upper left corner to enter the "Parameter Setting" interface, enter the corresponding "Parameter 1 Setting", set the current (ampere), set the test time, check the start station 1 (i.e. Group 1), turn on (check) the switch of the station to be tested, and click Save, as shown in Figure 6.
