For the great need of the high power output and high capacity power battery of electric vehicle, this article presents a method which classify the battery by EIS, and this method can get more information about the dynamics and electrode interface structure than the traditional ones. In order to make it closer to actual production, improvement was made for the disadvantages of the long time consuming...
For the purpose of predicting the state of charge of Lithium-ion rechargeable battery accurately, we introduced the method of electrochemical impedance spectroscopy to solve the problem. The experiment data of impedance spectroscopy is comprised of an inductive arc in the high-frequency region and two capacitive arcs in the low-frequency region, and by which the reasonable equivalent circuit of battery...
Lithium-ion battery impedance measurement using high-precision measuring instruments we have done, which spend much time on testing and cost high on equipments. In this paper, the studying on the lithium-ion battery, we analysis that the parameters of battery impedance model has a relation with the performance and state of battery, propose a simple detection method of internal resistance and ohm internal...
