Battery packs are composed of several smaller battery cells, and when certain cells fail due to overcharging or general wear, the entire cell can be swapped out with a new one. It’s important to use quality replacement batteries that match the capacity and voltage requirements set by the manufacturer of the original lithium battery pack.
A battery pack is out of balance when any property or state of those cells differs. Imbalanced cells lock away otherwise usable energy and increase battery degradation. Batteries that are out of balance cannot be fully charged or fully discharged, and the imbalance causes cells to wear and degrade at accelerated rates.
Ensure that all components of the lithium battery pack are present, including cells, wires, terminals, and case cover. Assemble the cells into their respective terminal connections. Securely connect each cell connection using cables or solder depending on your model's requirements.
The battery pack is composed of 100 series cells, with each series cell storing 10 kWh of energy. All cells are fully charged at 100% SoC except for one cell that is out of balance and is only at 90% SoC. As a result of this one cell, the entire pack is storing 999 kWh of energy, or 1000 kWh less the 1kWh from the cell that is not fully charged.
The same principle holds true for lithium battery packs. Even if each individual cell in the pack has been properly soldered and repaired, a weakly balanced battery with uneven voltages can still lead to an unreliable power source. To ensure that the entire battery pack works optimally, it's important to balance the cells within it.
A battery pack is a collection of battery cells packaged into an application-specific format. These can be as small as a single cell or as large as thousands of cells arranged in series and parallel configurations, along with any associated electronics and mechanical components. A battery cell is the smallest energy-storing unit of a battery.
