摘要
对蓄电池内阻测量的直流放电法和交流注入法进行了比较,采用小电流电量比较法,把蓄电池与高精密电阻串联,通过测量电流信号在二者上所消耗的电量来获得蓄电池的内阻。试验结果表明:所设计的蓄电池内阻测试仪具有操作简单、可靠性高、抗干扰能力强、测试结果准确等优点。
Regarding the deficiency of battery internal resistance on-line measurement at present,a new method based on low current consumption comparison was introduced.Through testing the consumes of power occurred on battery and high precision resistance,the internal resistance of battery could be calculated.It is proved by comparison that the new device can be easily operated and has strong jam-resistant ability,high reliablity and high accuracy.
