摘要：

Lithium-ion batteries continuously generate heat during work, So, when used as electric vehicle power supply, the battery pack may be quite hot and the temperature differences among monomers may be very large without effective thermal management measures, which will deteriorate its performance and lifespan. Generally uses various techniques such as forced air cooling, liquid circulation cooling, phase change material cooling and heat pipe cooling, have been applied in Battery thermal management system (BTMs) but with the shortcomings of complicated structure and high cost. In this work, pure copper fins were proposed for BTMs and experimental research was conducted. By changing the discharge rate and thickness of fins, the thermal characteristics of the battery pack under different working conditions is studied. The results showed that under the condition of natural convection, adding fin could significantly keep the temperature of battery pack from overheating, and improve the temperature distribution inside the battery pack. Thicker fins can meet the temperature requirements of higher discharge rate and greater discharge depth. © 2016, Chemical Industry Press. All right reserved.
