6 FAQs about [How to balance the series connected battery pack]

Do series-connected batteries need cell balancing?

As in single-cell applications, careful control of the charging and monitoring of the cells is essential to ensure safe operation and prevent premature aging or damage to the battery. However, unlike single-cell systems, series-connected battery stacks need cell balancing.

What is a balanced cell in a battery stack?

The cells in a battery stack are “balanced” when every cell in the stack possesses the same state of charge (SoC). SoC refers to the remaining capacity of an individual cell relative to its maximum capacity as the cell charges and discharges. All battery cells must be kept within a SoC range to avoid damage or lifetime degradation.

What is battery balancing?

By enabling the battery pack to work within safe and efficient factors, battery balancing strategies are used to equalize the voltages and the SOC among the cells. Numerous parameters such as the application’s particular needs, budget restrictions, and required efficiency are responsible for selection of ideal balancing techniques.

How does a multi-cell battery pack work?

The charge levels in a multi-cell battery pack are equalized with the assistance of a latest method i.e., Active Battery Balancing. In contrast to passive balancing, where extra energy is simply depleted as heat, active balancing tries to redisperse this extra energy to other cells in the pack that need charging.
