Design for intelligent charging system of Lead-acid batteries
Abstract：In this paper the design of lead-acid batteries intelligent charging system, content mainly includes to battery charging method of research and charging system design. In the battery principle and charging methods on the basis of study, the paper proposes the constant pressure and pulse current limiting charging charging combination of charging methods. This kind of charging methods can always to recharge current in overall approximation battery acceptable charging electric current curve, and throughout the charging period timely adopted remove battery polarization measures. Theoretical and experimental data shows that this model can greatly shorten charging charging time and improve charging efficiency.
Experimental results show that based on the intelligent charging 80196KB single-chip microcomputer control system, its high efficiency, regulating time quick good charging characteristics can get fully, make battery has higher use capacity and long cycle life, can meet the electric locomotive motive battery charging request, has a good application prospect for improving battery performance and reliability provides a new and effective way.
