Internal impedance of battery detection based on theory of chaotic Oscillator

Present a method with the chaotic oscillator to detect the battery internal impedance. Chaotic oscillator is sensitive to certain signal and immune to noise, so based on chaotic detection principle, and association the theory of AC internal impedance detection method, a new battery internal impedance detection method is presented. The on-line detection the battery internal impedance will be achieved. And the anti-interference circuit can be ignored, the measurement circuit is simplified. The experiment proved this method is effective.
