Use a multimeter to measure the overall voltage of the battery pack. Verify that individual cell voltages are within the manufacturer's specified range. Charging Test: Begin charging the battery pack and monitor the BMS operation. Discharging Test: Connect a load to the battery pack and observe the discharge process.
This is an important part of the process to ensure the environmental conditions in the battery pack are as stable as possible. Also, the enclosure lid needs to be removable so we apply a liquid sealing gasket, which is then sometimes cured using a UV process. To secure the lid we use flow drill screwing technology.
After ensuring all your connections are secure and insulated: Cover the Battery Pack: Place the assembled battery pack inside the appropriate shrink wrap tubing. Heat Application: Use a heat gun or lighter to shrink the tubing around the battery pack. This will help secure the cells together and provide a protective outer layer.
Connecting the BMS: B- Terminal: Connect to the main negative (-) terminal of the battery pack. B+ Terminal: Often already connected internally; check your BMS specifications. B1 (or B0): Connect to the most negative point (first cell's negative terminal). B2, B3, ...: Connect sequentially to the positive terminals of each cell in series.
Labeling: Mark the battery pack with important information like voltage, capacity, and safety warnings. After ensuring all your connections are secure and insulated: Cover the Battery Pack: Place the assembled battery pack inside the appropriate shrink wrap tubing.
When it comes to battery pack assembly it’s fair to say that quality control is everything; once the enclosure is sealed any failures are difficult and costly to rectify. So, the assembly processes have to be exacting, and as production volumes of this component rapidly increase, the assembly operations have to deliver precision and repeatability.
Cell Matching
What level of cell matching do you do prior to assembling a battery pack? Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. none, force the cell supplier to deliver cells matched to within +/-0.02V; none, gross balance the pack during first charge once built
