1.Passive equilibrium (dissipative equilibrium) Principle: By discharging through resistance, the energy of the battery with higher voltage is dissipated in the form of heat, making its voltage consistent with other batteries. Advantages: Simple circuit and low cost. Disadvantages: Energy waste, low efficiency, suitable for small capacity battery packs. 2.Active equilibrium (non dissipative equilibrium) Principle: Through energy transfer, the energy of batteries with higher voltage is transferre …

1.Improve battery pack performance Through equalization processing, the voltage and capacity of individual cells in the battery pack are made to converge, maximizing the available capacity of the battery pack. 2.Extend the lifespan of the battery pack Reduce overcharging and over-discharging of individual batteries, delay battery aging, and extend the service life of battery packs. 3.Enhance security To prevent thermal runaway caused by overcharging, overdischarging, or excessive temperature of …

Battery balancing processing is a key technology in battery management systems (BMS), mainly used to solve the inconsistency problem between individual cells in battery packs. 一、 Reasons why batteries need to be balanced Inconsistencies of individual batteries Due to factors such as manufacturing processes, material differences, and usage environments, individual cells in battery packs have differences in capacity, internal resistance, voltage, and other aspects. This inconsistency will g …
