What is internal resistance of a battery?
The internal resistance of a battery comprises several components that collectively determine how much opposition the battery presents to the flow of the electric current. These components can be broadly categorized into three main types: ohmic resistance, polarization internal resistance, and electrochemical impedance .
How do you determine the internal resistance of a battery?
The internal resistance increases with the degeneration of cells. The difference between the internal resistance at the end of battery life and the fresh stage is regarded as a basis for evaluating the SOH . This resistance, R, can be obtained by Ohm’s law or parameter identification based on an equivalent circuit model.
How to obtain a variation in capacity and resistance of a battery?
To obtain variation in capacity and resistance, the most commonly used approaches are to measure the current and voltage parameters of a battery to derive the two indicators. The approaches to acquiring the SOH from the current and voltage data can be categorized into two types: direct computation or model-based machine learning .
Is internal resistance a reliable indicator for estimating Soh of a battery?
Internal resistance is a valuable and reliable indicator for estimating the SOH of a battery . In the above works, only IC curve features were used as input parameters for modeling.
Can recursive least squares identify the internal resistance of batteries?
Then, a 2RC equivalent circuit model and the recursive least squares (RLS) algorithm were used to identify the internal resistance of batteries.
