基于SOC的锂电池组能量均衡控制策略研究
Research on energy balancing control strategy of lithium battery pack based on SOC
摘要
Abstract
The operation environment and manufacturing process cause the problem of state of charge (SOC) imbalance for cells.In order to solve the problem,the active balancing control strategy of lithium battery was proposed.Based on the accurate estimation of lithium battery SOC through unscented Kalman filter (UKF),with inductance as storage energy,the pulse width of MOSFET was modulated through fuzzy-PI algorithm to achieve the optimal control of balancing current,so energy is directly transferred from the unit with the highest SOC to the unit with the lowest SOC.Under the actual working conditions,the experiment platform was established based on the above analysis.The results show that the system is better than the traditional PI control system.关键词
