Popis: Four types of heat sources of a dynamic lithium-ion battery (LIB) during charge were studied, and temperature distributions inside the dynamic LIB caused by the four kinds of heat generation sources with different currents and temperatures during charge were simulated by using a electrochemical-thermal three-dimensional model. The ohmic heat is the largest heat resource with about 63.5% in the total heat generation during regular charge, the electrochemical reaction heat is dominant when the SOC is below around 10%, and the subsidiary reaction heat can not be ignored when the temperature in the battery is above 80°C. Current as well as ambient temperature plays a very important role in the overall thermal behaviors of the battery.
