Abstract:

In a low-temperature environment, the heating of batteries represents a crucial technical means of enhancing the performance of energy-storage systems, extending the lifespan of batteries, and ensuring their safety. The objective of this study is to address the issue of low-temperature heating in high-capacity lithium-ion batteries used for energy storage. Consequently, we propose a method, that makes use of an electric heating film, for rapid heating of the battery module. This approach takes into account the size effect of the battery and its anisotropic heat transport characteristics and is supported by numerical simulation and experimental testing. This study examines the impact of battery heating power, heating sites, and the multidimensional staggered synergistic heating method of the module on the temperature field of the battery and its warming rates. Results demonstrate a linear relationship between the rate of battery temperature increase and the input power applied to the heating film. When the heating power of the larger side of the battery is 350 W, the average temperature of the battery increased from -20 ℃ to 0 ℃ in 118 s, with a maximum temperature of 39.4 ℃. The battery pack reached equilibrium after 291 s. Double-side heating increased the temperature by 18 % compared to large-side heating but reduced material costs by approximately 38 %. The experimental results corroborated the precision of the simulation model and demonstrated that the scheme exhibits a brief heating time, high reliability, and the capacity to rapidly elevate the temperature of the battery pack. These research findings hold significant implications for the development and optimization of thermal management technology for household energy-storage devices.
