摘　　要：开发了一种新型用于室外传感器网络节点的微太阳能系统。在系统中,太阳能电池板将太阳能转换为电能,并存储于新型低自放电率的镍氢AAA电池中。为进一步延长电池的使用寿命,系统设计过程中采用了电池驱动的设计方法。超过4周的测试结果表明:本设计具有高可靠,低成本和高可行性等优势。A novel micro-solar power systems for outdoor sensor nodes is developed. In this system, a solar cell converts the sunlight into electrical energy power which is stored into a new type of battery pack consisting of low self-discharge rate NiMH AAA size batteries. In order to get an extra improvement of battery life, battery-driven design technologies are used in the design process of the system. The results of field test lasting more than 4 weeks show that this new system has advantage of reliabitity,low cost and easy to implement.
