Study on the fast charging method of lead-acid battery with negative pulse discharge

In order to improve electric vehicle lead-acid battery charging speed, analysis the feasibility of shortening the charging time used the charge method with negative pulse discharge, presenting the negative pulse parameters determined method for the fast charging with pulse discharge, determined the negative pulse amplitude and negative pulse duration in the pulse charge with negative pulse. Experiments show that the determined parameters with this method has some Advantages such as short charging time, small temperature rise etc, and the method of negative pulse parameters determined can used for different capacity of lead-acid batteries.
