Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
A battery balancer is a device or circuit designed to equalize the charge levels across multiple cells in a battery pack. It is a critical component of a battery management system (BMS) that ensures the battery pack’s optimal performance, safety, and longevity. A typical battery balancer consists of several key components:
needs two key things to balance a battery pack correctly: balancing circuitry and balancing algorithms. While a few methods exist to implement balancing circuitry, they all rely on balancing algorithms to know which cells to balance and when. So far, we have been assuming that the BMS knows the SoC and the amount of energy in each series cell.
Battery balancing equalizes the state of charge (SOC) across all cells in a multi-cell battery pack. This technique maximizes the battery pack’s overall capacity and lifespan while ensuring safe operation.
In Li-ion batteries which have very low self-discharge and therefore accumulative unbalance per cycle is usually less than 0.1%, bypass current of internal FETs is sufficient to keep the pack continuously balanced.
Control logic: Microcontroller or dedicated IC to manage the balancing process. Communication interface: This is for integration with the overall battery management system. Protection circuits: To prevent overcharging, over-discharging, and thermal issues. Temperature sensors: These monitor cell and ambient temperatures.
