Charging Gun Plug-In Life Testing Machine

ZJ-CBSM01
This equipment is suitable for the charging gun plug and socket breaking capacity and normal operation life test, locking device test, and plug-in force test. It uses servo electric cylinders, servo motors, air cylinders, etc. as power, and a small fixture to clamp the sample. The touch screen and programmable controller (PLC) are the control center. It has superior performance, easy operation, and a high degree of automation. It can clamp the charging gun, automatically immerse the charging gun in acid rain solution, saline solution, and muddy water solution in turn, and then automatically take it out and insert it into the charging gun holder. The last power-on is 1.5 hours, and the action is repeated to simulate the plug-in life of the charging gun outdoors. All test items meet the requirements of GB/T18187.1-2015, GB/T20234.1-2023, and GB/T11918.1-2014.

Charging Interface Cable Bending Test Machine

ZJ-WQ01
This equipment must meet the test requirements of Chapter 6.2.10.4 of GB/T20234.1-2023, Chapter 24.4 of GB/T11918.1-2014, and Chapter 26.4 of IEC 62196-1:2022, and is suitable for bending tests of non-detachable electrical accessories such as charging guns.
This equipment is controlled by PLC and touch screen, which is convenient to control. The angle, speed and number of times can be set. Fix the sample on the fixture, add a certain load, and shake the fixture left and right during the test. After a certain number of times, check its wire breakage rate, or check its total number of swings when it cannot be powered on. This machine can count automatically. When the sample is bent to the point where it cannot be powered on, the instrument automatically stops working. This equipment can also be tested with load, and a load wiring port is reserved.

Inrush Current

ZJ-YL300A
The impulse current tester produced by our company is made in accordance with the requirements of the standard IEC61851-1: 2017-02, version 3.0 Electric vehicle conductive charging system Part 1: General requirements Chapter 12.2.6.
The equipment is controlled by PLC+touch screen.
Meet the following standards:
According to ISO 17409: 2015 Section 8.2.2, AC electric vehicle supply equipment should be able to withstand surge current.
The following values are specified in ISO 17409:
• After closing the contactor in the electric vehicle supply equipment at the peak value of the supply voltage, the electric vehicle supply equipment should be able to withstand a peak of 230 A for a duration of 100µs.
• In the next second, the electric vehicle supply equipment should be able to withstand 30 A (RMS).
According to /EC TS 61439-7, compliance with this requirement can be verified by testing the entire electric vehicle supply equipment or a single switch device.
The protection device should be selected so that it will not trip due to the inrush current.
