This paper belongs to a two-part study dealing with thermal effects in Li-ion pouch battery cells. Here, a SPICE-compatible battery model suited for circuit-based simulations is presented. The model accounts for the thermo-electrochemical mechanisms taking place in batteries. Since it provides fast, yet accurate, results, the approach is aimed at supporting designers of electric/electronic systems based on storage supplies. Although the proposed solution can be applied to a generic product, a Li-ion pouch battery cell in nickel-manganese-cobalt was considered as a case study. The model accuracy is verified by comparing PSPICE results with those obtained through the 3-D finite-element method simulations described in Part I.

Abstract
This paper belongs to a two-part study dealing with thermal effects in Li-ion pouch battery cells. Here, a SPICE-compatible battery model suited for circuit-based simulations is presented. The model accounts for the thermo-electrochemical mechanisms taking place in batteries. Since it provides fast, yet accurate, results, the approach is aimed at supporting designers of electric/electronic systems based on storage supplies. Although the proposed solution can be applied to a generic product, a Li-ion pouch battery cell in nickel-manganese-cobalt was considered as a case study. The model accuracy is verified by comparing PSPICE results with those obtained through the 3-D finite-element method simulations described in Part I.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
