Battery pack balancing maintenance

How to balance a battery pack correctly?

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.

What is battery balancing?

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.

What is active battery balancing?

An advanced method of managing an equal SOC across the battery pack’s cell is known as active battery balancing. Instead of dissipating the excess energy, the active balancing redistributes it, resulting in an increased efficiency and performance at the expense of elevated complexity and cost.

What happens if a battery pack is out of balance?

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.

What is a battery balancer?

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:

How does a battery management system work?

The process typically involves the following steps: Cell monitoring: The battery management system (BMS) continuously monitors the voltage and sometimes temperature of each cell in the pack. Imbalance detection: The BMS identifies cells with higher or lower charge levels compared to the average.
