To analyze the thermal behaviour of the battery pack, the heat generation model of battery cells is critical. Generally, there are two catogories of heat generation models. The first one is based on thermo-electrochemical battery model and studies the mechanisim of heat generation.
In the simple method proposed previously by the authors to estimate heat generation in lithium-ion batteries, 7, 8 a most simple internal equivalent circuit is used, namely, a series connection of emf E and an equivalent internal resistance Req as shown in Figure 1.
Thermal analysis for an EV battery pack is conducted at two extreme operation conditions for real engineering problems. The Bernardi's heat generation model is employed and the reversible heat is taken into account. Theoretical model with reversible heat taken into account achieves better results.
In both operation conditions, the heat generation model as stated in Section 3.1 is applied to describe the amount of heat generated, and note that the obtained heating power from the EV battery pack in cooling condition is shown in Fig. 7. Fig. 7. The heating power of the EV battery pack in cooling condition.
The method is of strong robustness against changes in ambient tempera-tures and convection conditions. Heat generation inside a battery cell regardless of sources are covered. Estimation of heat generation in lithium-ion batteries (LiBs) is critical for enhancing battery performance and safety.
