基于混沌理论的蓄电池内阻检测的研究

Battery internal resistance measurement based on chaotic theory

研究了一种运用混沌振子来检测蓄电池内阻的方法。运用混沌振子检测系统对初始值敏感,而对噪声具有很强抑制作用的原理,结合交流法测量蓄电池内阻的原理,实现蓄电池内阻在线检测,可以忽略抗干扰电路的设计,简化测量电路。实验证明了利用本系统进行蓄电池检测是可行的。

A method of battery internal resistance detection based on chaotic theory was studied in this paper. Using the principle that chaotic oscillator is sensitive to initial value but immune to noise, and combining to AC internal resistance detection method, a new battery internal resistance detection method was proposed. This method simplifies the measuring circuit, ignores the anti-interference circuit, and realizes the on-line detection： The experiments prove that this method is effective.
