Abstract

A reduced wide-temperature-range electro-thermal model, which is based on the frequency-dependent equation, is presented and validated under different frequencies and temperatures. The temperature dependence of resistances and capacitances in a wide temperature range is proposed. In contrast to state-of-the-art electro-thermal models, the presented identification for thermal parameters, which are validated with a very small error, does not require expensive thermal equipment, like calorimeter and is free from the challenges for their installations. Simulation results exhibit good agreement with experiments, where the maximum relative voltage error and temperature error are less than 2.31% and 0.89°C, respectively. The reduced model, thanks to its reliability and simplified characteristic, provides a promising candidate for development of optimal charging strategies in a wide temperature range, for prediction of the electrical and thermal performance of batteries in on-board battery management system.
