A generalized methodology for lithium-ion cells characterization and lumped electro-thermal modelling

•Electro-thermal modelling is needed to understand how lithium-ion cells generate heat.•ECM need a wide testing with respect of temperature, SOC, current to map parameters.•Extrapolation models can be coupled to experiments to get info outside test area.•Electro-thermal lumped modelling can be easily integrated within BMS control strategy.•The model can describe cell behavior without needing microscopic phenomena knowledge.
