Description

一种光能驱动的手机、手电筒等电池的充电器
技术领域
本发明涉及一种光能驱动的手机、手电筒等电池的充电器。
背景技术
太阳能电池具有光生伏打效应，在光的作用下即产生电压，只要选择合适的太阳能电池功率，就能方便的将太阳能电池对手机、手电筒等电池进行充电。用脉冲电流对镉镍电池充电，能对电池起去极化作用，可获得较好的充电效果。
发明内容
本发明一种光能驱动的手机、手电筒等电池的充电器，公开一种太阳能电池为驱动功率，对手机、手电筒等电池进行充电的实用技术。
一种光能驱动的手机、手电筒灯电池的充电器，其电路由太阳能电池组、三端稳压电路、脉冲发生器电路、充电自动充电、停止及指示电路等组成。
附图说明
附图是一种光能驱动的手机、手电筒等电池的充电器的电路原理图。
具体实施方式
如附图所示，IC1是太阳能电池组，选用输出电压为17V的开路电压，容量根据需要选定。利用太阳能电池在白天有光照射时产生光附效应而产生电压，并且这个电压值在15V以上，送IC2进行稳压。IC2是三端稳压器，选用的型号为7805，其输出的电压送下一级电路为工作电压。
如附图所示，IC3及外围电路组成脉宽调制输出电路，IC3是型号为555的IC芯片，选择合适的R1、R2、R3的值，IC3就能输出约90％的占空比脉冲电压值，由IC3的3端输出送D5对电池E进行脉冲充电。
如附图所示，D3、D4、D5组成充电指示及电池充满电自停充电电路。D3是双端稳压器电路，选择稳压值为3.7V，D4是发光二极管，选用绿色，在电池被充满电时，D4亮，表示被充电池已充满电。D3与D4串联，其两端的电压值为手机电池约3.7V，加上发光二极管D5的管压降约0.7V共4.4V。而D5和被充电池组成的电路中，D5是发光二极管，选用红色，在电池充电时，D5亮，表示被充电池在进行充电中。E是被充电电池，当被充电池充满电时，D5、E两端的电压达到4.4V。即当电池充满电时，其端口电压达到D3击穿电压，此时，D4有电流通过，D4发亮，而D5熄灭，表示电池已充满电。
