If the cell manufacturer can deliver cells with a proven quality history of OCV within +/-0.02V then you will be able to assemble and charge these cells without gross balancing. However, you will need to consider a few things: 1. cell manufacture, formation, ageing end of line testing all. .
This is what you are probably trying to avoid as it can take hours or even days for the pack balancing to remove large SoC differences. An SoC difference of 10% on a 100Ah cell will take. .
This is the approach used by the satellite industry and adopted by motorsport. The cells undergo a number of checks from visual inspection, capacity and internal resistance. .
Prior to assembling the battery packs you can charge/discharge all of the cells to a defined voltage. This ensures all of the cells are matched in SoC prior to assembly. .
Similar to option 3, but using just OCV to group cells such that the initial SoC of the cells in a pack will not require gross balancing. This does. Cell matching involves carefully selecting and grouping cells with similar characteristics, such as: Capacity: The amount of charge a cell can store. Voltage: The electrical potential of a cell.
