The Stability

In this paper, the merit and disadvantage of existing measurement methods for battery internal resistance are firstly analyzed. Then an online internal resistance measurement based on AC impedance method is proposed, which can increase the stability of the excitation source and enhance the performance of the filtered feedback signal. The method can be used to measure the small resistance of lithium-ion battery precisely. Experimental results show that the proposed method is accurate.
