thermal design and simulation of mini-channel cold plate for water-cooled large size prismatic li-ion battery

car electrification is being promoted as a potential alternative to reducing carbon intensity in transportation. lithium-ion batteries are suitable for hybrid electric vehicles (hevs) and pure electric vehicles (evs), and temperature control in lithium batteries is critical for long-term performance and durability. unfortunately, battery thermal management (btm) has not received much attention due to poor understanding of battery thermal behavior. cell performance changes dramatically with temperature, but improves with temperature if a proper operating temperature window is maintained. this article provides an overview of two aspects that are the development of battery thermal model and thermal management strategies. the thermal effects of lithium ion batteries in terms of heat escape and response at cold temperatures are studied and heat generation methods are discussed with the aim of accurate thermal analysis of the battery. in addition, current btm strategies used by automotive suppliers will be reviewed to identify imposing challenges and significant gaps between research and practice. optimizing existing btms and exploring new technologies are needed to reduce the thermal effects of the battery, and efforts to prioritize btms should be made to improve temperature uniformity throughout the battery pack, increase battery life, and increase the safety of large packages. based on the paired model of a three-dimensional thermal model, the thermal behaviors of lithium-ion batteries under discharge-charge cycle with different currents are investigated.
