Active balancing is also called non-energy dissipative balancing. Its principle is to transfer the energy in the high-energy cell to the low-energy cell during the charge and discharge cycle, so that the charge in the battery PACK is redistributed, thereby shortening the charging time and extending the discharge time. In terms of application scenarios, active balancing is more suitable for large-capacity and high-number lithium battery pack applications.
Active balancing uses the principle of energy transfer and distribution, so the energy utilization rate is higher than that of passive balancing.
In practical applications, active balancing technology is also widely regarded as more efficient and reasonable. For example, Enerkey's self-developed bidirectional DC-DC active balancing chip uses advanced intelligent algorithms to quickly and effectively compensate for the differences in battery packs, ensure battery consistency, extend the service life of the battery pack and the mean time between failures, and effectively improve the economic benefits of the product's entire life cycle.
