Battery Pack Testing Machine (120V 100A) After wiring the semi-finished battery pack, we go for capacity testing using the individual Battery Capacity Testing Machine. Using an advanced computer software, each process will be programmed before connecting the machine with semi-finished battery pack.
Testing battery packs for leaks is a critical safety step for automakers. Due to material instability, any test that uses air to build pressure inside the pack can cause the volume to expand like a balloon, increasing the measured leak rate.
Check process data for every battery pack and verify it. Final inspection also includes visual and total quality check of the pack. Final Packing before delivering to customer Clean the final product and pack the product in cotton case as per the instruction. Now it’s ready to dispatch.
All parties must account for the added cost and time resulting from testing the printed circuit board assembly before assembling the battery pack. However, it pays dividends when the long term cost savings, thorough testing, troubleshooting, and ease of repair result in a high quality end product with a lower instance of failure in the field.
Battery module and pack testing involves very little testing of the internal chemical reactions of the individual cells. Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics.
