How to optimize the cooling and heat dissipation system of lithium battery pack?

For the optimization of the cooling and heat dissipation system of the lithium battery pack, an improved optimization framework based on adaptive ensemble of surrogate models and swarm optimization algorithm (AESMPSO) is proposed. PSO algorithm can effectively avoid the optimization process from falling into local optimality and premature.

Does a battery pack have a complex heat dissipation mechanism?

Thermal flow fields of different air outlet modes were considered, and the results of this research provide a theoretical basis for further revealing the complex heat dissipation mechanism of the battery pack. The heat convection is considered the heat conduction with a heat source in the field synergy principle.

How does a battery design affect heat dissipation?

The design intent is to keep the package changes to the minimum but with better cooling efficiency. The results show that the locations and shapes of inlets and outlets have significant impact on the battery heat dissipation. A design is proposed to minimize the temperature variation among all battery cells.

What is the corresponding design variable for lithium battery cooling & heat dissipation?

The research of X.H. Hao et al. shows that the coolant temperature within a certain temperature range has a certain influence on the cooling effect of the lithium battery cooling and heat dissipation system, so the inlet coolant temperature T (K) is set as the corresponding design variable.

What factors affect the cooling and heat dissipation system of lithium battery?

Based on the previous screening of the factors affecting the cooling and heat dissipation system of the lithium battery pack, four factors are selected: cooling plate thickness m1 (mm), cooling wall thickness m2 (mm), inlet coolant temperature T (K) and velocity of inlet coolant v (m/s).

Does air cooling improve the heat dissipation of a battery pack?

In addition, exchanging the air inlet and outlet can improve the synergy between the flow field and the temperature field which in turn improves the heat dissipation. The conclusion of this paper can provide a reference to the heat dissipation design of the battery pack under air cooling.
