VRLA电池免浮充节能技术研究

Research of the energy saving technology for the VRLA battery's free float charging

目前阀控密封铅蓄电池作为通信用备用电源，备用状态下均采用浮充电方式进行充电管理。由于铅蓄电池对温度非常敏感，要求工作温度在20～30℃，冬天和夏天分别利用空调进行温度调节。文章介绍了阀控铅蓄电池的温度特性，分析目前蓄电池浮充管理中存在的问题，提出了一种蓄电池浮充节能技术。

Currently, as a power supply for communication, valve-regulated lead-acid （VRLA） battery is managed by float charging. The lead-acid battery is very sensitive to the temperature, so the ambient temperature is required between 20℃ and 30℃, and air-condition is used to regulate temperature in winter and summer. The temperature propety of valve-regulated lead-acid batteries is introduced in this paper, and the existing problems in the management of float charging for lead-acid batteries is analyzed. And an energy-saving technology for VRLA battery＇s free float charging is pointed put.
