| Abstract: | According to lithium battery pack equalization control algorithm,this paper proposes a novel control scheme for lithium battery pack that can realize energy equalization.The design of fuzzy-PI is represented in detail,including the controller’s inputs and outputs,fuzzy logic rules base and the set of PI parameters.PI control is introduced into fuzzy control to form fuzzy-PI control,which integrates the advantage including fast response of fuzzy-PI,having no steady-state static error of PI and so on,the equalization efficiency and precision are improved.Experimental results show that this scheme can improve the problem that the control precision of fuzzy control application is poor in battery charging and discharging energy equilibrium process,and realize more efficient equalization. |
