Equipment Overview

This test system can perform potential equalization test for electrical vehicles’ high-voltage components during the assembly process of the entire vehicle. To ensure that the potential difference between each high-voltage exposed conductive parts is minimized, we need to make the potential equalization test by the requirements of standards between each high-voltage parts shell and electric platform, as well as any two exposed conductive parts that can be touched by people at same time.

Principle
1. Take a specified current from a power source with no load not exceeding 12KV, then apply it among the ground wire of the vehicle charging port, the component exposed conductive shell and vehicle frame, we calculate the ground resistance value by measured voltage drop.

2. To test conduction resistance between the ground wire of each vehicle charging interface, the exposed conductive shell of the parts and the vehicle frame with a distance no more than 2.5m.

Main Functions

1. Multi-channel: Integrated 10 channel potential equalization.

2. Screen display: 21.5-inch true color LCD screen is used, and the interface of the test process is visible, which is convenient for observation and judgment.
 

3. Open platform: It equipped with test program editing function, test project editing function, test report editing and printing function, user permission setting function etc.
 

4. Scan code function: It can record the vehicle VIN number, VSN number and main accessories number, and automatically associate the barcode to print the test report after test is completed.
 

5. Permission management: multi-level permission setting, which is convenient for management.
 

6. Data management: Manage various data, protect the integrity and security of the data, and have functions such as query and export to meet the data management needs of the production line.
 

7. Safety protection: Over-current protection, over-voltage protection, under-voltage protection, leakage current protection and emergency protection, etc.
 

8. Massive data: Support massive data storage and analysis; MES system docking, etc.
 

9. Flexible startup: Support multiple startup methods such as scan code startup, button startup, remote startup, etc.

10. Intelligent judgment: The key indicators all have the function of setting the upper and lower limits, automatically judge, and effectively prevent the occurrence of missed inspections.
