Fig. 2. Heat generation rate versus DOD or SOC for a single battery during discharge-charge cycles with different C-rates at 25 °C ambient the 0.5C charge process is thus well explained. Quite a few publi- cations described the thermal behavior and heat generation mech- anisms in NMC or NCA (nickel-cobalt-aluminum) lithium-ion batteries during charge/discharge operations. Further details can be found in, e.g. [52,53].
