Design and Research of Battery Charged Intelligent System

The thesis researches on the theory on fast-charging method of lead-acid battery. A new type of charging pattern was proposed. The current can match the acceptance curve of the lead-acid battery proposed by J.A.Mas very well. With the intermission and discharge in the course of the charge, it avoids the gas-generation and overtemperature. About charging control methods, the system selects an integrated control method to judge whether batteries was full-charge or not. A Fuzzy control algorithm was used to realize charging course. The experiment result indicates that fuzzy control has a fast response speed, a good steady state precision and a strong anti-interference.
