二、 EOL Safety and DCIR Testing For Electric Vehicles
(1)Entrance
(2)Communication Information Reading
(3) Insulation and Withstanding Voltage Performance Test
*
EOL test system: Detect the insulation voltage and leakage of the battery pack.
* High-power 750V300A equipment: Test the impedance of the vehicle power harness and check whether the entire line is connected reliably.
* Calculate the DC impedance value by calculating the high-power charging device, and check whether the wiring port of the battery pack is normal;
* The battery polarization can be detected by the internal voltage value of the battery pack to determine the battery health.
* Hand-held information collection unit: Collect three electric information of electric car.
