Battery packs for cars, laptops, E-bikes etc. are all assembled from batteries that are very similar, preferably from the same batch. Then the voltages, capacities and series resistances should match well enough to assemble a battery pack without issues.
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.
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.
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. This can take a long time as the maintenance balancing currents are generally very small compared to the Ah ratings of the cells (1 to 3mA/Ah).
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 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.
High-quality cells continue to perform longer than the lower-quality counterparts, and fading is more even and controlled. Lower-grade cells, on the other hand, diverge more quickly with use and time, and failures due to cell mismatch are more widespread. Cell mismatch is a common cause of failure in industrial batteries.
Battery packs for cars, laptops, E-bikes etc. are all assembled from batteries that are very similar, preferably from the same batch. Then the voltages, capacities and series resistances should match well enough to assemble a battery pack without issues.
