Experimental study of a novel strategy to construct the battery thermal management module by using tubular phase change material units

Preparation of Composite Cooling Boards Composed of Thermal Conductive Silica Gel and Phase Change Materials for Battery Thermal Management

“…The preparation of the CPCM was based on our previous work with some modifications. 10 As shown in Figure 1, predetermined amounts of PA were melted in an aluminum container and the container was placed in a 90 °C oil bath. After complete melting, EG and ER with different mass contents were added successively into the container under continuous stirring for 2 h. The obtained slurry was then poured into molds with different specifications and cooled to room temperature.…”

“…Since the 20th century, global warming and energy shortage problems have become increasingly serious. Due to their higher energy utilization efficiency and lower emissions of pollutants, electric vehicles (EVs) have received intensive attention from governments and public worldwide in the past decade. − Power battery modules/packs are the core component by serving as the main energy source of EVs, which are commonly constructed by lithium-ion batteries (LIBs). − Their performance is closely related to the driving mileage, power output, energy consumption, and safety of EVs. ,− Generally, an operating temperature in the range of 20–50 °C is desired for LIBs and a temperature difference (Δ T ) less than 5 °C in the entire module is required to guarantee the consistency of cells. − However, thermal safety issues derived from the (localized) overheating of the battery module have been perplexing researchers and manufacturers. ,− Thus, designing an advanced battery thermal management (BTM) system becomes necessary to strictly control the temperature rise and Δ T . ,− …”

“…Conventional BTM technologies, including air cooling and liquid cooling, suffer from the relatively low cooling efficiency and complex installation along with a leakage risk. ,− Fortunately, a kind of passive BTM technology based on phase change materials (PCMs) developed in recent years is believed to simultaneously achieve a high temperature-control capability and simplify the structure of the battery module. , It is based on the principle that PCMs can absorb/release abundant latent heat during the melting/solidifying process. Thus, numerous investigations have been focused on developing advanced composite PCMs (CPCMs) to overcome the drawbacks of pure PCMs, such as poor thermal conductivity and shape stability.…”

Recent Developments of Thermal Management Strategies for Lithium‐Ion Batteries: A State‐of‐The‐Art Review

“…Similar studies on PCM units-based hybrid BTMS were also presented in other literature. [124][125][126][127] Furthermore, inspired by the microstructure of shark skin, Yang et al [128] applied a bionic heat sink in battery cooling, which combined with PCM in cavities and axial air cooling. The results suggested that compared with normal cases, the assemble of bionic structure could modify temperature consistency as well as energy consumption and also exhibited good reliability under various dynamic conditions.…”

Liquid cooling system for battery modules with boron nitride based thermal conductivity silicone grease

“…3,4 Thus, there is a need for an efficient battery thermal management system that enables the timely dissipation of heat. Air, 5–7 liquid, 8–10 and phase-change material (PCM) cooling 11–13 are the three principal thermal management technologies. However, owing to the technical level or properties of PCM defects, thermal interface materials (TIMs) are usually used to fill the microgaps in different shapes of liquid- or PCM-cooling systems to improve the heat transfer efficiency.…”
