Systematic derivation and validation of a reduced thermal-electrochemical model for lithium-ion batteries using asymptotic methods

The widely used Doyle-Fuller-Newman (DFN) model for lithium-ion batteries is too computationally expensive certain applications, which has motivated the appearance of a plethora simpler models. These models are usually posed in an ad hoc manner, leading to inconsistencies with DFN and multiple formulations same model, Single Particle Model (SPM) being very good example latter. In this work, we discuss concept SPM-type showing that, despite found literature, these always follow structure, extend discussion accounting thermal effects. Then, present Thermal electrolyte (TSPMe) derived systematic manner using asymptotic techniques. validation TSPMe against shows high accuracy computational cost over forty times smaller. comparison experimental data that does reasonable job predicting behaviour real battery, but parameter set required obtain accurate predictions.
