A state-of-the-art review on battery cell balancing strategies
Balancing is achieved through two primary methods: passive balancing, which dissipates excess energy from overcharged cells as heat using resistors, and active balancing, which transfers

Comprehensive Optimization of Active Cell Balancing Strategies in Electric Vehicle Battery Management Systems By author / February 1, 2026 As we witness the rapid global adoption of
Active balancing uses a more sophisticated approach. Instead of wasting excess energy, the system transfers charge from higher-voltage cells to lower-voltage cells via inductors, capacitors,
At its core, active cell balancing is a sophisticated method of moving energy from high-voltage cells to low-voltage cells within a battery pack. Unlike passive balancing, which simply
As an alternative to passive balancing, active balancing uses power conversion to redistribute charge among the cells in a battery pack. This allows for a higher balancing current, lower heat generation,
Cell balancing is a technique that ensures voltage equalization among battery cells. After balancing, all cells in the battery pack achieve nearly the same SoC. As illustrated in Figure 1, there are two
Explore how active cell balancing uses efficient energy transfer to prevent cell mismatch, maximizing high-voltage battery capacity and lifespan.
While passive balancing methods convert excessive energy into heat, active balancing ensures that the energy is transferred rather than dissipated. That''s why active balancing systems
Considering the significant contribution of cell balancing in battery management system (BMS), this study provides a detailed overview of cell balancing methods and classification based on
In energy storage systems where every watt counts, the energy saved with active balancing translates to: Active systems often achieve 90–95% energy transfer efficiency, while
