In addition, a three-dimensional heat dissipation model is established for a lithium iron phosphate battery, and the heat generation model is coupled with the three-dimensional model to analyze the internal temperature field and temperature rise characteristics of a lithium iron battery.
The simulation results show that the lithium iron battery discharges under the same ambient temperature and different C rates, and the battery temperature continuously increases with C.
Therefore, lithium iron batteries have become an ideal power source for electric vehicles. 1 However, the thermal safety problems of lithium iron battery cannot be ignored. If the heat generated by the battery cannot be dissipated in time, it will cause the battery temperature to rise, or even thermal runaway.
Through the research on the module temperature rise and battery temperature difference of the four flow channel schemes, it is found that the battery with the serial runner scheme is better balanced and can better meet the operating temperature requirements of lithium iron phosphate batteries.
a The maximum temperature curve for the battery surface, b the difference in temperature, and c the field synergy angle with time at different initial temperatures Across four distinct ambient temperature scenarios, the battery pack exhibits natural heat dissipation ranging from 7.9 to 5.6 °C at its highest and lowest temperatures, respectively.
Lithium plating is a specific effect that occurs on the surface of graphite and other carbon-based anodes, which leads to the loss of capacity at low temperatures. High temperature conditions accelerate the thermal aging and may shorten the lifetime of LIBs. Heat generation within the batteries is another considerable factor at high temperatures.
