“…They consist of an evaporator section, a condenser section, and a wick structure that transports the working fluid (Figure 15). The working fluid evaporates in response to applied heat in the evaporator section, absorbing the latent heat of vaporization before transferring it to the condenser section, where it condenses and releases it back [90]. In battery cooling applications the evaporator section is placed touching with the surface of battery and the condenser section in the heat sink which is cooled by forced circulation.…”

The thermal concerns, such as capacity loss, uneven temperature distribution and thermal runaway of the battery packs made of lithium-ion batteries (LIB) used in electric vehicles (EV), limits its applicability, especially in situations of high-power demand. This article analyses the causes of heat generation in lithium-ion battery packs, focusing on their dominance over total heat generation. It discusses the thermal issues arising from heat generation, their root causes, and influencing parameters. Further, it examines the effect of cooling systems on peak battery temperature and temperature uniformity, as well as their design, operating, and performance parameters. The review suggests that, when designing a cooling system, entropic heating should be considered alongside Joule heating during low discharge rates and high temperatures, which are the conditions that prevail when an EV cruises on highways in hot weather. Capacity fade of battery is caused by temperature-dependent factors such as the growth of the SEI layer, rise in separator resistance, and active material loss. Hence an effective battery cooling system should maintain a temperature range of 15°C to 35°C and ‘ΔTmax’ below 6°C. Out of the reviewed cooling systems, air cooling is found to be simple and cost effective, but inefficient for large battery packs. PCM based cooling technique offers greater temperature uniformity but is sensitive to melting point. Liquid cooling is most efficient but adds cost and complexity. Evaporative cooling can serve as a middle ground between air and liquid cooling with further research to put it into practice. The future research in battery thermal management may focus lowering the energy consumption of the cooling systems by taking into account, the precise cooling needs as per the modes of battery operation.

“…The size of the heat pipe is determined by the heat load it experiences. Constant Conductance heat Pipes (CCHP) are the basic and standard isothermal heat pipes, whose thermal conductivity can be varied by changing physical properties such as pore diameter, porosity, and permeability [Meseguer et al, 2012a]. The application of heat pipes in small satellites is successful due to their simplicity, low mass, and higher thermal conductivity compared to copper rods.…”

Chandrakanth Joshi for their time and advice in various capacities. Mr. Lamphrecht's guidance on spacecraft thermal analysis and control techniques were essential to shaping my research to one that is purposeful and meaningful to the thermal community.I extend my gratitude to CR Technologies for providing me with a free license of the Thermal Desktop Software to support my research simulations and other student projects that I led at the lab. Specifically. I am thankful to Ms. Cindy Beer for her help and communication with installing the software packages and offering advice to my queries.
