This study extracts health characteristics of lithium batteries from charge and discharge data with incremental capacity analysis to predict the capacity of lithium-ion batteries. Meanwhile
a method for estimating the state of health of lithium-ion batteries is proposed based on the improved Harris hawk optimization algorithm (IHHO) and support vector regression (SVR). To address the problem that the Harris hawk optimization algorithm (HHO) tends to stagnate at local optima
the IHHO algorithm introduces a pooling mechanism and a migrating search strategy based on the HHO algorithm
while modifying the position update equation to prevent premature convergence. Based on comparisons using the CEC2017 test suite
the optimization capabilities of IHHO and HHO algorithms are evaluated. This shows that the IHHO algorithm has a higher convergence speed and optimization accuracy. For some test functions
the optimization accuracy of the IHHO algorithm is improved by more than three orders of magnitude
effectively avoiding premature convergence. In addition
the comparative experiments are conducted on the NASA lithium-ion battery dataset to optimize the standard SVR with IHHO and HHO algorithms. The results show that IHHO-SVR significantly improves the prediction accuracy of the state of health
reducing the root mean square error by more than 40% compared to the HHO-SVR. In addition
comparisons with other literature models indicate the superior performance of the IHHO-SVR model. For certain prediction results
the root mean square error of IHHO-SVR is reduced by at least 15%.
