It is the existing technology that grid power V~ transforms into direct current source V1 from the positive direction for battery charging.This article recommends the technology path which is a positive from V1 to V2 and V2 negative external load Rf two-w%由电网电源V-变换成直流电流源V1后从正方向对蓄电池V2充电是现有技术。本文是推荐一种由V1正向V2,V2又负向外接负载Rf的双向交替电流对蓄电池充电的技术路径,是在遵循马斯定律的理论计算又结合具体的控制电路可真实实施的一种技术路径。所达到的效果是现有技术基础上:Ⅰ段速充电速率提高16倍;蓄电池循环使用周期寿命延长一倍;电能转换效率提升10%。
