Brief analysis of energy storage battery heat dissipation technology

Does battery pack have heat dissipation performance?

The research on the heat dissipation performance of the battery pack is the current research hotspot in the electric vehicle industry. In this paper, battery modules and battery pack are simplified to heat source and semi-closed chamber, respectively.

How does the heat dissipation performance of a semi closed chamber affect battery performance?

Therefore, the heat dissipation performance of the semi closed chamber which is based on air cooling can directly represent the temperature distribution of the battery pack as well as its performance.

Why is a battery thermal management system important?

A battery thermal management system is crucial to improve the performance, lifetime, and safety of Li-ion batteries. The research on the heat dissipation performance of the battery pack is the current research hotspot in the electric vehicle industry.

How does temperature affect battery thermal management?

With an increase in cooling flow rate and a decrease in temperature, the heat exchange between the lithium-ion battery pack and the coolant gradually tends to balance. No datasets were generated or analysed during the current study. Kim J, Oh J, Lee H (2019) Review on battery thermal management system for electric vehicles.

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.

Does temperature gradient affect heat dissipation performance of air-cooled battery pack?

Thermal flow fields of different air outlet modes were considered in this paper, and the results show that the heat dissipation performance of air-cooled battery pack increases with the improvement of the synergy degree between velocity field and temperature gradient field.
