“…Since the 1970s, many PCM have been studied for TES applications in buildings and in solar systems [1][2][3][4][8][9][10][11][12][13]. The use of PCM for TES systems in the 20-25 • C (293-298 K) range is being increasingly studied as it corresponds to ambient temperature applications which are of widespread concern, especially regarding thermal comfort in buildings or vehicles [14][15][16]. The use of PCM-based TES systems succeeds in maintaining suitable temperature conditions and is also sustainable and affordable [16,17].…”

Characterization of Fatty Acids as Biobased Organic Materials for Latent Heat Storage

This work aims to characterize phase change materials (PCM) for thermal energy storage in buildings (thermal comfort). Fatty acids, biobased organic PCM, are attractive candidates for integration into active or passive storage systems for targeted application. Three pure fatty acids (capric, myristic and palmitic acids) and two eutectic mixtures (capric-myristic and capric-palmitic acids) are studied in this paper. Although the main storage properties of pure fatty acids have already been investigated and reported in the literature, the information available on the eutectic mixtures is very limited (only melting temperature and enthalpy). This paper presents a complete experimental characterization of these pure and mixed fatty acids, including measurements of their main thermophysical properties (melting temperature and enthalpy, specific heats and densities in solid and liquid states, thermal conductivity, thermal diffusivity as well as viscosity) and the properties of interest regarding the system integrating the PCM (energy density, volume expansion). The storage performances of the studied mixtures are also compared to those of most commonly used PCM (salt hydrates and paraffins).

“…According to the simulation results, the cabin temperature was held on 15 °C and 21% increase in the electric range was observed. Similar study was presented in [143] where the development of a heat exchanger with PCM was introduced. The design tests indicated that the electric range could be extended by 20% in winter conditions.…”

The technical maturity and rapidly increasing market share of electrified vehicles have given more importance to the cabin thermal management. Efficient thermal management has a key role to maintain adequate electric operating range, protect components from aging and ensure passenger comfort. This research comprehensively reviews the cabin thermal management systems for electrified vehicles. Various vehicle cabin thermal modeling techniques and the key concepts for cabin thermal comfort have been discussed. Different technical and operational solutions of the cabin thermal management in hot and cold climate conditions are evaluated. The recent developments including heat pumps, thermal system control, passive thermal management, and cabin preconditioning to increase thermal management efficiency are analyzed. The results show that increasing amount of research is focusing on improving the thermal efficiency of the individual electrical components and the vehicle level systems. However, new solutions will be required for reducing the cabin thermal load under hot conditions and improving the heating system operational flexibility and efficiency in cold climates.

“…Ma et al [23] suggested battery energy control strategies, reporting that approximately 30% of energy consumption reduction is obtained under different control modes. Wang et al [24] developed a novel thermal control system by storing the heat when the vehicle's battery is charging and then releasing the heat during driving. It showed that the driving range is increased by approximately 20%.…”

A Comprehensive Overview of Basic Research on Human Thermal Management in Future Mobility: Considerations, Challenges, and Methods

Thermal management in automobiles is necessary to minimize energy usage while achieving a high level of occupant thermal perception. As the freedom of in-vehicle activity increases with autonomous driving, considering convenience becomes even more important, and, at the same time, the need for thermal management in electric vehicles is expected to increase. While it is necessary to consider the characteristics of the future mobility environment, there is still a lack of research that takes into account these changes in thermal management and proposes future research directions. Therefore, the purpose of this study is to explore basic research directions based on national R&D project cases and to provide a comprehensive overview. The environmental changes that need to be considered in thermal management research include the diversification of future transportation types and usage purpose diversification, the characteristics of electric vehicles, changes in the interior and exterior design of autonomous vehicles, personalized air conditioning environments, and dynamic thermal management according to occupant in-vehicle activity. This study provides an understanding of the overall field, and can help identify challenges, solutions, and ideas. Although this study provides conceptual considerations for research directions, future research is needed to identify detailed factors related to technology, environment, and human factors.
