Lithium battery matching battery pack
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. 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 measurement before finally selecting the best cells. This is an expensive approach. 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 mean that you need to measure the. 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.

FAQs about Lithium battery matching battery pack
What makes a good battery pack?
Battery packs with well-matched cells perform better than those in which the cell or group of cells differ in serial connection. Quality Li-ion cells have uniform capacity and low self-discharge when new. Adding cell balancing is beneficial especially as the pack ages and the performance of each cell decreases at its own pace.
How many cells are in a battery pack?
Six battery packs (each containing two cells connected in parallel, as depicted in Fig. 5) were tested using the method described below. For further reference within this paper, two parallel-connected cells are called a “cell group”. The current to each cell and the temperature of each cell were recorded.
How important is resistance matching in battery packs?
We demonstrate the importance of resistance matching in battery packs. At 4.5C charge and discharge, 20% resistance mismatch reduces lifetime by 40%. We quantitatively explain experimental results using a model of SEI formation. Resistance mismatch causes uneven current sharing.
Do nickel based batteries match each other?
Cell matching according to capacity is important, especially for industrial batteries, and no perfect match is possible. If slightly off, nickel-based cells adapt to each other after a few charge/discharge cycles similar to the players on a winning sports team.
When should a battery pack be balanced?
Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. If the cells are very different in State of Charge (SoC) when assembled the Battery Management System (BMS) will have to gross balance the cells on the first charge.
