This research uses improved particle swarm optimization (IPSO) for parameter estimation of li-ion battery and provides a new model for that. To achieve an efficient and accurate model, exponential structure is used to model the internal resistors and capacitors. It is necessary to carry out the exact measurements on the output of battery in laboratory conditions. Finally a comparison is performed between the voltage obtained in practical mode and from optimized coefficients.
