The study on high-efficiency,fast and damage-free charging to lead-acid battery

An in-depth study on the electrochemical mechanism of lead-acid battery.Based on a number of charging and discharging experiments,a charging thought is put forward on the variable structure-fuzzy control and neural network predictor,a new-type Buck/Boost topology that uses a two-unit IPM to perform charger and depolarized.The experiment results indicated that by application of new control strategy,the charging efficiency was raised to about 90%,the charging period was reduced to within one and a half hours,and there was no apparent electrolyte temperature-rise,which means high efficiency,fast and damage-free charge is realized.
