In addition, the type of coolant due to the difference in thermal conductivity also affects the cooling effect of the cooling and heat dissipation system of the lithium battery pack.
Although there have been several studies of the thermal behavior of lead-acid , , , lithium-ion , and lithium-polymer batteries , , , , heat dissipation designs are seldom mentioned.
Cooling effect of battery pack was improved by adjusting the battery spacings. The excessively high temperature of lithium-ion battery greatly affects battery working performance. To improve the heat dissipation of battery pack, many researches have been done on the velocity of cooling air, channel shape, etc.
Thus, the use of a heat pipe in lithium-ion batteries to improve heat dissipation represents an innovation. A two-dimensional transient thermal model has also been developed to predict the heat dissipation behavior of lithium-ion batteries. Finally, theoretical predictions obtained from this model are compared with experimental values. 2.
Consequently, temperature distribution and heat dissipation are important factors in the development of thermal management strategies for lithium-ion batteries.
A two-dimensional, transient heat-transfer model for different methods of heat dissipation is used to simulate the temperature distribution in lithium-ion batteries. The experimental and simulation results show that cooling by natural convection is not an effective means for removing heat from the battery system.
