摘　　要：以STC89LE516AD和UC3842为核心,实现蓄电池可接受充电电流曲线跟踪技术的智能充电电路设计。该电路可根据蓄电池端电压自动改变充电电流大小,并通过全程窄脉冲放电消除了充电过程中的极化现象,缩短了充电时间,提高了充电效率。Taking STC89LE516AD and UC3842 as the core, an intelligent charging circuit which can realize receivable charging electric current curve tracking technology for the battery was designed. To shorten charging time and improve charging efficiency, the circuit can change the charging electric current automatically according to real-time voltage of the battery, and dispel the polarization phenomenon by narrowing pulse discharge in the whole course.
