The Lithium Battery Pack Equilibrium Strategies Based on Flyback Converter

Aiming at the problems in bidirectional anti-excitation circuit in equilibrium strategy, the thesis giresa equilibrium approach based on residual energy classification. First, the paper classify the battery by residual value, According to the result of classification, the paper calculates the target equilibrium by using circuit model. Then the paper establishes a equilibrium simulation of the statistics by using Matlab. The results indicate the method fully uses of the charactenstic of the bidirectional anti-excitation circuit. being flexible and expanding the cruising power.
