Product Description
1.1 Device Introduction
This AC charging gun aging test machine solution adopts advanced computer control and energy feedback load, making the test system more intelligent, energy-saving, and environmentally friendly.
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 testing.
Energy saving: Energy feedback load is used to realize energy recovery, so as to achieve energy saving.
Environmental protection: The electric energy is fed back to the power grid without generating a lot of heat, avoiding the increase of the ambient temperature of the test site.
Traceability: Test data can be queried and traced in real time.

Three Test Principle
3.1 Test Principle Diagram
The test principle 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.
3.2 Test Control Strategy
The equipment wiring diagram 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 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 disconnected. If it cannot be charged or there is no product, KM1A is closed and KM1B is disconnected, 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 disconnected. If it cannot be charged or there is no product, KM2A is closed and KM2B is disconnected, 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 disconnected. If it cannot be charged or there is no product, KM12A is closed and KM12B is disconnected, 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.
3.3 Energy Feedback Load
The load adopts a regenerative load. A regenerative load is also called an energy feedback electronic load. Compared with ordinary resistance loads, its working method is to use power electronic conversion technology to recycle the output energy of the power supply under test on the premise of completing the test power experiment, and feed the electric energy back to the power grid without pollution. This saves energy and does not generate a lot of heat, avoiding the problem of rising ambient temperature in the test site.
