Abstract: Effective fast charging is of great importance in the application of lithium-ion battery packs. In this article, a combined battery pack charging system is constructed by integrating the charger and cell-to-cell equalizers, which can excellently solve the cell imbalance problem in the battery pack.
Why is the battery pack temperature contour of LIC module improved?
Fig. 16 depicts the battery pack temperature contour of the LIC module in the two-phase cooling mode. It can be noticed that the module uniformity under two-phase heat transfer condition was further improved, which was attributed to the generation, growth and detachment of bubbles on the cell surface increasing the fluidity of the FS49.
How to dissipate the heat of battery pack?
Zhou et al. combined the heat pipe with the LIC system to dissipate the heat of battery pack by using Novec 649 with good dielectric properties. Study showed that the peak module temperature and the peak temperature difference were limited to below 47℃ and 2.1℃, respectively.
Does adiabatic boundary condition affect battery pack temperature?
Moreover, the heat accumulation in the lower portion of the battery pack was more pronounced due to the adiabatic boundary condition on the bottom surface of the battery in the calculation process. Fig. 15. The battery pack temperature contour of the LIC module under three different discharging rates at the ambient temperature of 20℃.
How does heat dissipation affect a battery pack?
As a result, the disturbance in the upper portion of the battery pack was more intense, i.e., it corresponds to a stronger heat dissipation flux, which further reduces the heat accumulation at the upper portion of the battery pack. Fig. 16.
Can polypropylene Wick reduce temperature inhomogeneity of battery pack?
In addition, the polypropylene wick prepared in this study can effectively reduce the peak temperature and temperature inhomogeneity of the battery pack under the condition of low filling rate, and further increase the energy density of the system (13.14 % increase at 25 % filling rate compared with 100 % filling rate).
