Product Description
1.1 Device Introduction
This AC charging gun aging test machine solution adopts advanced computer control and feedback load, and the test system has more intelligent, energy-saving and environmental protection features.
1) Intelligent: The software automatically monitors aging, and automatically cuts off the power and prompts alarm information in case of failure or defect
The equipment automatically short-circuits faulty samples, and other stations continue to test
2) Energy saving: Energy feedback load is used to realize energy recovery, so as to achieve energy saving
3) Environmental protection: The electric energy is fed back to the power grid, without generating a lot of heat, and avoiding the increase of the ambient temperature of the test site
4) Traceability: Test data can be queried and traced in real time
1.2 Applicable Products
It is used for aging test of single-phase AC charging gun pile to ensure that the product meets the requirements. It is applicable to GB/T 18487.1-2015, IEC 62196-2-2016, SAE J1772-2017, SAE J1772-2017 electric vehicle AC charging gun/pile product aging test. The product is shown in the figure below:
Standard: Single-phase national standard, European standard, American standard
Load voltage: Single-phase AC 0~300V (external input, power supply is provided by the user)
Load current: 1~32A continuously adjustable
1.3 Test Schematic Diagram
The test schematic diagram is shown in the figure below. KM represents the contactor, 13A represents the AC socket, the black square represents the AC charging gun socket, the control guide is the control guide module, and M2 represents the AC charging gun mode 2.
1.4 Test Control Principle
The wiring diagram of the equipment takes 10 products as an example and is connected in series at the rear end. The maximum number of tests is limited by the voltage drop and the maximum allowable range. This equipment has 2 groups, and each group of 10 products is tested online at the same time. Note: KMXA and KMXB are interlocked wiring and cannot be closed at the same time.
Brief introduction of electrical action principle:
Station 1, insert the product, the KM contactor is closed, the M2 product is energized, and S2 is closed to start charging through the control guide. If the product at station 1 is charging normally, KM1B is closed and KM1A is opened. If there is no charging or no product, KM1A is closed and KM1B is opened, and the electricity is directly transmitted to station 2;
Station 2, insert the product, the KM contactor is closed, the M2 product is energized, and S2 is closed to start charging through the control guide. If the product at station 2 is charging normally, KM2B is closed and KM2A is opened. If there is no charging or no product, KM2A is closed and KM2B is opened, and the electricity is directly transmitted to station 3;
And so on……
Station 12, insert the product, the KM contactor is closed, the M2 product is energized, and S2 is closed to start charging through the control guide. If the product at station 2 is charging normally, KM12B is closed and KM12A is opened. If there is no charging or no product, KM12A is closed and KM12B is opened, and the electricity is directly transmitted to the load contactor;
The power meter sequentially and cyclically measures the aging voltage and aging current of the product to be tested, and stops aging when a defect is found.
1.5 Feedback Load
The load adopts a feedback load. The feedback load is also called an energy feedback 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 under test without pollution, and feed the electric energy back to the power grid without pollution, which not only saves energy but also does not generate a lot of heat, avoiding the problem of rising ambient temperature in the test site.
1.6 Software
The system software has one-key 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 console is designed according to ergonomics, and the equipment can perform self-inspection.
(1) The operation software adopts a Chinese interface, which is simple and easy to learn;
(2) Computerized operation, all tests are completed at once
(3) Can be connected to MES system
(4) Can scan code to test
(5) Test data traceability
(6) Test data can be automatically saved as EXECL or TXT documents
