Battery heat builds up quickly, dissipates slowly, and rises swiftly in the early stages of discharge, when the temperature is close to that of the surrounding air. Once the battery has been depleted for some time, the heat generation and dissipation capabilities are about equal, and the battery’s temperature rise becomes gradual.
The connection between the heat pipe and the battery wall pays an important role in heat dissipation. Inserting the heat pipe in to an aluminum fin appears to be suitable for reducing the rise in temperature and maintaining a uniform temperature distribution on the surface of the battery. 1. Introduction
Consequently, temperature distribution and heat dissipation are important factors in the development of thermal management strategies for lithium-ion batteries.
The temperature distribution of a battery is represented by a cloud map. The temperature limits of the battery are 47.42 °C and 41.92 °C respectively, and are interpolation-controlled at 5.5 °C. The heat inside the battery pack is difficult to emit to the outside world and is affected by the thermal radiation from the surrounding areas, leading to heat concentration.
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.
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.
