摘要
现代通信系统中,蓄电池是直流供电系统的最后一道安全保障屏障。蓄电池的好坏及供电质量,直接影响到整个通信系统的安全可靠运行。蓄电池内阻检测,是评价蓄电池质量的重要参数。本文详细介绍交流法测量蓄电池内阻的基本原理,依据该方法存在的缺陷,提出直接采样相移法测量蓄电池内阻的新方法,并用硬件电路实现该功能。
In modern communication systems, Power Supply System. The storage battery is the last security barrier of the DC quality of storage battery and power supply affect the stable operation of the entire communication system directly. The Battery internal resistance measurement is the major parameters for evaluating battery＇s quality. This paper specifically introduces the general principles for measuring the battery resistance by AC testing methods, and according to the defects of this method, presents a new method of using direct sampling phase resistance and realize this function with the hardware shifting method to measure the battery internal circuit.
