电池内阻的测量

Measuring Internal Resistance of the Battery

介绍一种新的电池内阻测量方法—双电阻测量法,对该测量法选取电阻需满足的条件进行了推导。研制了一种基于该方法的电池内阻测量装置,本文详述其硬件组成和工作原理,给出了电路组成框图和程序流程图。该装置采用单片机智能控制,自动化程度高,测量快速准确,硬件结构简单,抗干扰性强,具有较高的稳定性和可靠性。

A new method to measure internal resistance of the battery—double resistances measurment method was introduced in this paper . Required conditions of chosing resistances in the method were worked out . A new kind of measuring device based on the method was developed . Hardwares and working principles of the device were described in detail,the frame diagram of circuit costitution and procedure diagram were given too . Controlled by SCM,the device can work automatically,quickly and accurately.The device has simple constitution,high anti-interference performance,and good stability and reliability .
