The following steps outline how to calculate the Battery Heat Generation. First, determine the current flowing through the battery (I). Next, determine the internal resistance of the battery (R). After inserting the values and calculating the result, check your answer with the calculator above.
This Battery heat power loss calculator calculates the power loss in the form of heat that a battery produces due to its internal resistance. Every battery has some internal resistance due to a battery not being a perfect conductor and its inherent internal composition and makeup. Current is the flow of electrons.
Battery normal heat generation is a result of the loading current during operation. However, the amplitude of the electrochemical heat generation rate also depends on cell dimensions, SOCs, and even cell temperatures.
That is: lf a multicell battery is involved, then the total heat is the heat generated or absorbed by each cell multiplied by the number of cells in the battery (N). For example, during discharge, the total heat for a battery would be given by: where
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.
A straightforward and accurate Li-ion battery heat generation estimation method is presented for online usage. 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.
