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方法。详细介绍了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,提出了直接采样相移法测量蓄电池内阻的新方法,并用硬件电路实现了该功能。
In modern communication systems,storage battery is the last security barrier for the DC power supply system.The 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 method to evaluate battery′s quality.The general principles for measuring the battery resistance by AC testing methods are introduced.And according to the defects of this method,a new method of using direct sampling phase shifting method to measure the battery internal resistance is presented.And this function is realized with the hardware circuit.
