As the use of lithium batteries for energy storage systems is worldwide increasing both for stationary and mobile applications, the possibility to model the batteries electrical and thermal behaviour is fundamental. A complete battery is usually composed by several minor size cells linked together: hence, for a whole battery model, a single cell model is necessary. This paper shows the development of a simplified electro-thermal model for small size lithium cells, able to estimate voltage and temperature with a maximum average error lower than 3% between model and experimental data. The cell electrical and thermal parameters are calibrated through experimental tests performed in University of Pisa laboratories, in collaboration with the company Toyota Material Handling Manufacturing Italy.

Abstract
As the use of lithium batteries for energy storage systems is worldwide increasing both for stationary and mobile applications, the possibility to model the batteries electrical and thermal behaviour is fundamental. A complete battery is usually composed by several minor size cells linked together: hence, for a whole battery model, a single cell model is necessary. This paper shows the development of a simplified electro-thermal model for small size lithium cells, able to estimate voltage and temperature with a maximum average error lower than 3% between model and experimental data. The cell electrical and thermal parameters are calibrated through experimental tests performed in University of Pisa laboratories, in collaboration with the company Toyota Material Handling Manufacturing Italy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
