NEW ITERATIVE IDENTIFICATION METHOD FOR POWER BATTERY EQUIVALENT CIRCUIT MODEL PARAMETER

摘要

Disclosed is a new iterative identification method power battery equivalent circuit model parameter comprising: based on an iterative learning theory, firstly dividing model parameters into two groups, wherein one group of parameters is set with an initial value; identifying the other group of parameters using the least squares method, if the other group of parameters meet a set range requirement, setting the obtained parameters as known; and similarly identifying the first group of parameters using the least squares method, if not meeting the set range requirement, setting the parameters to be zero; and continuing an iterative cycle until all the parameters meet the requirement and then exiting the iterative cycle.
