The thermal conductivity represents a key parameter for the consideration of temperature control and thermal inhomogeneities in batteries. A high-effective thermal conductivity will entail lower temperature gradients and thus a more homogeneous temperature distribution, which is considered beneficial for a longer lifetime of battery cells.
Also, temperature uniformity is crucial for efficient and safe battery thermal management. Temperature variations can lead to performance issues, reduced lifespan, and even safety risks such as thermal runaway. Uniformity in temperatures within battery thermal management systems is crucial for several reasons: 1.
Due to the significant heat generation that li-batteries produce while they are operating, the temperature difference inside the battery module rises. This reduces the operating safety of battery and limits its life. Therefore, maintaining safe battery temperatures requires efficient thermal management using both active and passive.
Thermal management systems of batteries must be sufficient to control energy loss, reduce carbon emission, and be capable of long-run heat and thermal energy storage and to help in gaining a longer battery life. Compared to metal oxide nanoparticles, CNTs are quite pricey despite their efficacy in improving the PCM's thermal properties.
Compared to natural convection and aluminum plate cooling, heat pipe cooling significantly improves heat dissipation and temperature uniformity due to its high thermal conductivity , . Integrating a flat plate Loop Heat Pipe (LHP) beneath the module in EVs marks a significant advancement in battery thermal management.
The next generation of EV batteries impose higher energy compressed in the battery, which means more catastrophic thermal runaway and fire explosion in case of accident. This principle suggests various design implications from material aspects in the cell to the thermal management aspect of the BTMS.
