计量终端备用电池控制方法及应用

Application of Backup Battery Control for Electric Energy Terminals

计量终端的备用电池在长期使用中容易出现容量衰减快、无法提供大电流等问题.基于此,提出了一种适用于备用电池模块的控制方法,具有电池充放电、容量检测以及电池激活等功能,解决电池过充过放、容量大幅下降、保护等问题;介绍了备用电池模块的各种运行模式工作机制,放电实验和充电实验证明,通过LED负载和超级电容的有机组合,可实现电池模块在线激活维护,提高终端备用电源的可靠性.

The backup batteries in electric energy terminals tend to reduce capacity and be unable to produce sufficient current in long term use.This paper proposes a novel management method suitable for backup battery,which is able to charge,discharge,activate battery and test the capacity.These functions are useful to protect battery and prolong its life.The operation models and working mechanism are described in details.Two experiments have been conducted to show the performance of the method which could improve the reliability of backup battery.
