Thermal management of a Li-ion battery pack employing water evaporation

Thermal management for a tube–shell Li-ion battery pack using water evaporation coupled with forced air cooling

“…However, more mass of the other phase-change materials such as paraffin with a latent heat of 220 kJ kg À1 should be used to achieve the same goal. 44…”

“…This helped control the temperature rise of the battery body, which had the advantages of low cost and simple structure. 44 Zhao et al invented a BTMS incorporating exible hydrogel lms. They tested the BTMS through highintensity discharging operation and abnormal heat release processes, validating an economic and efficient approach in mitigating the thermal surge of LIBs.…”

Experimental study of a direct evaporative cooling approach for Li‐ion battery thermal management

“…BTMSs can be categorized into active and passive modes 3,4 . The active BTMSs circulate air or liquid through fans or pumps in cooling channels to extract the heat generated by batteries, while the passive BTMSs manage battery heat generation without consuming supplementary energy, and the examples include phase change materials cooling, 5‐10 hydrogel cooling, 11‐13 and boiling liquid cooling 14‐16 . As the modern trend toward increasing batteries' power density and fast charging performance, that is, higher C rates (for example, 2 C indicates the current that can fully charge or discharge a battery in 1/2 hour), the parasitic heat generation in batteries can increase, which poses extra challenges on the BTMSs.…”

“…In relevant studies, a heat pipe‐based BTMS was combined with the evaporative cooling to manage the heat of prismatic battery packs, in which the heat generated from the batteries was indirectly absorbed by water evaporation through the assist of heat pipes 30 . In Reference 12, water filled hydrogel films were adhered to the surfaces of a prismatic battery pack to absorb the heat through the natural evaporation of water in the films.…”

Experimental Investigation on a Thermoelectric Cooler for Thermal Management of a Lithium-Ion Battery Module

“…The rapid development of global industrialization has increased the greenhouse gas emissions and nonrenewable energy shortage, which are urgent concerns for the entire society [1,2]. To effectively address serious environmental problems, pure electric vehicles (EVs) and hybrid EVs as green power equipment and environment-friendly transport tools compared to traditional diesel locomotives are developed [3][4][5][6]. Lithium-ion batteries have many advantages, such as high power density, high energy density, long lifetime, and less self-discharge; they play an important role in the fields of EV and energy storage station [7][8][9][10].…”
