At the same ambient temperature, the lithium iron battery is discharged to the cutoff voltage at 1 C and 3 C, and the average increase in the temperature of the lithium iron battery cell area reaches 4.5 K and 15 K, respectively.
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 temperature rise is mainly affected by Joule heat, and when the lithium iron battery is discharged at the same C but different ambient temperatures, the temperature rise of the lithium iron battery shows a decreasing trend with the increase in ambient temperature in a certain temperature range.
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.
In the realm of energy storage, lithium iron phosphate (LiFePO4) batteries have emerged as a popular choice due to their high energy density, long cycle life, and enhanced safety features.
