6 FAQs about [How to match the batteries in the 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.
What happens if the battery cell matching standard is less strict?
If the matching standard is stricter, then the probability of the battery cell voltage difference will be smaller. On the contrary, if the battery cell matching standard is less strict or if there is no matching at all, the probability of the cell voltage difference will be greater, and this will result in premature battery failure.
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.
What happens if a battery pack is cycled?
When cycled, all batteries show large capacity losses over 18 cycles, but the greatest decrease occurs with the pack exhibiting 12 percent capacity mismatch. Battery packs with well-matched cells perform better than those in which the cell or group of cells differ in serial connection.
What is the difference between a battery and a pack?
The capacity differences between the two sections are 5, 6, 7 and 12 percent. When cycled, all batteries show large capacity losses over 18 cycles, but the greatest decrease occurs with the pack exhibiting 12 percent capacity mismatch.
