“…Some work was presented in literature concerning coupled metal hydride reactions. Fang et al [33] investigated coupled catalyzed MgH 2 -TiV 0.62 Mn 1.5 for heating and cooling of cabins in electric vehicles. Some boundary conditions differ to the presented study (regeneration temperature level of 270°C, material partly combined with expanded natural graphite, ambient temperature of 20°C) which limits comparability.…”

“…Magnesium hydride is considered a prime candidate material for hydrogen storage and thermal energy storage owing to its high hydrogen storage capacity (7.76 wt %), good reversibility, and low cost. − However, there are two major impediments that have prevented the practical use of MgH 2 despite a huge amount of research that has been reported around the globe. One of the issues is that MgH 2 suffers from poor kinetics during hydrogen absorption and desorption reactions.…”

Magnesium hydride has long been regarded as a promising candidate material for hydrogen and heat storage due to its high hydrogen capacity, reversibility, and low cost. Catalytic doping has been demonstrated as one of the most effective methods to improve hydrogen storage properties of MgH2. In this study, amorphous Ti45Cu41Ni9Zr5 and Ti40Cu47Zr10Sn3 alloys are used as additives for MgH2. Nanostructured MgH2 doped with amorphous or crystalline TiCu-based alloys are prepared by using a high-energy mechanochemical synthesis method. Results show that the amorphous TiCu additives provide enhanced catalytic effects compared to crystalline alloys of the same composition. Doping MgH2 using an amorphous Ti45Cu41Ni9Zr5 alloy yielded improved dehydrogenation kinetics compared to using crystalline Ti40Cu47Zr10Sn3 alloy. The analysis using transmission electron microscopy reveals that there are nanostructured catalytic particles uniformly distributed in the amorphous TiCu-catalyzed MgH2. The MgH2 system catalyzed by amorphous TiCu-based alloy shows little degradation during hydrogenation and dehydrogenation cycling at 300 °C. The amorphous TiCu-based catalysts are thermally stable at temperatures up to 360 °C. Heating the amorphous Ti45Cu41Ni9Zr5-catalyzed MgH2 to temperatures above 360 °C led to disproportionation of the catalyst alloy and the formation of MgCu2 and Ti2Cu. In addition, PCI analysis of the amorphous Ti45Cu41Ni9Zr5-catalyzed MgH2 shows a slight increase in hydrogen equilibrium pressure, resulting in a reaction enthalpy of −78.7 kJ/mol·H2 and an entropy of 145.0 J/K·mol·H2. The entropy calculated from this study is approximately 10 J/K·mol·H2 higher than values previously reported for undoped and catalyzed Mg–H systems.

“…A thermal battery concept by exploiting advanced metal hydrides was introduced for vehicle cabin cooling and heating. The idea of having higher energy density was based on the differences occurring in hydrogen equilibrium pressures [118]. The working hydrides have matching thermodynamic properties, consisting of MgH2 (high temperature hydride) and TiMnV (low temperature hydride).…”

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.
