Thus, "4.2V * 3A * 30/60h" is a straight calculation of (though need some more considerations) power we are drawing from the battery, but not the power to generate heat. Heat is generated from "inefficiency", offset to an ideal power source. I would say the main source of heat is the chemical reaction and loading on internal impedance.
In Sect. 7.2, in order to obtain the current amplitude and frequency of the AC heating, the battery is modeled as a whole for electro-thermal coupling, without taking into account the internal heat conduction of the battery. In contrast, the electrochemical - thermal coupling model developed in this chapter is intended to further analyze the ...

According to the principle of conservation of energy, the battery temperature evolution can be expressed as (1) d T d t · c p · m = h · S c e l l · (T − T a) where t is the test time, h is the heat transfer coefficient between the tested battery and its ambient, T a is the ambient temperature that is maintained at -20 °C, and m, T, c p and S …
As can be seen, the lowest temperature position in the battery region increases exponentially, where the temperature increases slowly at the beginning and then rapidly after 800 s of heating.
The results show that the main heat source of the battery temperature rise comes from the reaction heat during the charging and discharging of the battery, and the internal contact resistance is the cause of the significant temperature gradient inside the battery [7]. A two-dimensional model using the empirical Arrhenius formula and the energy ...
