Based on this status, it puts forward a kind of seal free maintenance lead-acid battery used for intelligence charge design scheme in this thesis.With regard to all sorts of problems for battery charging appeared in the process, analyzes the existing solutions, and put forward a kind of lead acid battery to realize four stages of intelligent charging slow pulse charger design scheme.
