Product Description
1.1 Applicable Products
Used for aging test of single-phase AC charging gun piles to ensure that the product meets the requirements for shipment. 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 physical product is shown in the figure below:
Standard: Single-phase and three-phase national standard, European standard, American standard
Load voltage: Single-phase AC 0~300V Three-phase 0~420V (external input, power supply 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, taking 10 products as an example, 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 simultaneously. 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 closes, the M2 product is energized, and S2 starts charging through the control guide. If the product at station 1 is charging normally, KM1B closes and KM1A opens. If there is no charging or no product, KM1A closes and KM1B opens, and the electricity is directly transmitted to station 2;
Station 2, insert the product, the KM contactor closes, the M2 product is energized, and S2 starts charging through the control guide. If the product at station 2 is charging normally, KM2B closes and KM2A opens. If there is no charging or no product, KM2A closes and KM2B opens, and the electricity is directly transmitted to station 3;
And so on……
Station 10, insert the product, the KM contactor closes, the M2 product is energized, and S2 starts charging through the control guide. If the product at station 2 is charging normally, KM12B closes and KM12A opens. If there is no charging or no product, KM12A closes and KM12B opens, 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 under test, and stops aging when a defect is found.
1.5 Feedback Load
The load adopts a feedback load. A feedback 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 and reuse 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 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.
