“…In particular, thermal discomfort will reduce the work e ciency but also affect people's moods, and even adversely affect their physical health (Banerjee et al 2020). Thus, a comfortable outdoor thermal environment can motivate people to actively enjoy outside areas, which will improve their physical and mental health (Nastase et al 2022). At present, people are paying more attention to climate issues and how to improve the comfort of the environment.…”

At present, urban haze pollution is a major problem that affects the outdoor environmental quality, thereby hindering the construction of an ecological civilization and healthy urban development. The urban outdoor thermal environment also influences the urban physical environment. Both the thermal environment and air environment have important effects on the subjective comfort evaluations of people. In this study, four typical spaces on a university campus in Xi'an, China, were selected to investigate the thermal environment and air environment in outdoor spaces. The particulate matter in the air was divided into three different concentrations. The adaptive thermal comfort due to the interaction between the outdoor thermal environment and air pollution was studied based on questionnaires and field measurements, and a strategy was developed for optimizing the thermal comfort of outdoor public space environments. The results showed that the influence of the thermal air quality environment on subjective comfort clearly varied among different spaces. The influence of haze pollution on subjective comfort was greater in high and low temperature environments, but less obvious in a moderate temperature environment. When the PM2.5 particle concentration was greater than 100 µg/m3, the evaluation of respiratory comfort was low in the high temperature environment. The perception of air pollution was less sensitive in the thermal environment in covered road sections. Heat pollution and air pollution will affect human health to varying degrees. People with mental diseases are affected most by the outdoor thermal environment and patients with respiratory diseases are affected most by haze pollution.

“…The air conditioning system in an EV is powered by the vehicle's battery, which means that it draws energy from the same source that powers the vehicle's propulsion system [ 17 ], and thus leads to a reduction in the vehicle's range. Regardless of technological advances employing effective energy-saving strategies, the impact of air conditioning on the range of an EV can be quite significant with some studies reporting its reduction of up to 50% due to cabin cooling requirements during a hot season [ 18 ] although other studies using newer EVs driven at speeds close to 100 km/h show range losses below 20% for outside temperatures close to 40 °C [ 19 ]. On the other hand, a climatization system operated in cooling mode may only represent 14% of the load of an EV during an urban driving cycle in a mild summer country [ 20 ].…”

“…They also assessed the impact of using PCM at different heating powers, air‐cooling coefficients, ambient temperatures, and case emissivity on thermal management performance. Nastase et al [ 28 ] reviewed the thermal comfort theory in electric vehicle design and proposed an intelligent system that can heat or cool passengers locally while reducing electrical power consumption. Liu et al [ 29 ] proposed a cooperative control algorithm incorporating the dynamic models of air conditioning systems, model predictive control (MPC), and intermittent ventilation.…”

New energy vehicle (NEV) is a significant solution to the energy crisis and global warming. The promotion and widespread use of NEVs will depend on developing and modernizing their core technologies and components. As the three core systems of NEVs, the thermal management of the battery, motor, and electric control systems is increasingly essential. Herein, the precharge circuit's thermal management strategy is improved by studying the precharge resistor's thermal performance. Both intermittent and continuous high voltages are applied to the precharge resistor to study its temperature‐rising characteristics. It is demonstrated that thickening electrode can lengthen the precharge resistor's short‐circuit durability, increase its transient heat storage capacity during a short circuit of the precharge circuit, and reduce the maximum temperature of the resistor's shell and resistance wire. When the thickness is 3 mm, and the eccentricity is 18.5 mm, the heat storage capacity of the resistor under continuous high voltage can be increased by up to 82.32%, and that under intermittent high voltage can be increased by up to 52.92%.
