Special Issue Information

Dear Colleagues,

Although new energy vehicles have entered the stage of large-scale industrialization, energy-saving technology has always been the core technology pursued in the automotive industry. In particular, the low-temperature environment has a significant impact on the driving range of electric vehicles, and “low-temperature anxiety” has become a pain point in the user experience of electric vehicle marketization. Based on this background, the vehicle thermal management system and the comprehensive collaborative control of thermal management and energy management become particularly important. The thermal management system for new energy vehicles has undergone rapid development from decentralized to integrated, and has now achieved high integration and assembly, which can better recycle and utilize onboard thermal energy in order to improve vehicle energy efficiency. Moreover, the control of thermal management has gradually been deeply integrated with energy management strategies in order to solve the problems of thermal management and optimal energy consumption control for new energy vehicles.

This Special Issue, entitled “New Energy Vehicle Thermal and Energy Management Systems Design and Collaborative Control”, aims to explore the latest technologies in integrated thermal and energy management, as well as the related intelligent control of new energy vehicles, and to explore the potential to further optimize the overall performance of vehicle energy efficiency, comfort, battery life, and other aspects.

This Special Issue invites original research papers to explore the challenges and opportunities of thermal and energy management in new energy vehicle, including the following:

  • The design and analysis of thermal management system components;
  • The design and analysis of thermal management system configuration;
  • Optimization methods for energy management of new energy vehicle;
  • Integrated collaborative optimization and intelligent control methods for thermal and energy management;
  • Thermal management and energy management simulation modeling technology;
  • Thermal management system testing and verification technology;
  • The data mining and big data analysis of thermal and energy management.

Over 50% of an engine’s energy dissipates via the exhaust and cooling systems, leading to considerable energy loss. Effectively harnessing the waste heat generated by the engine is a critical avenue for enhancing energy efficiency. Traditional exhaust heat recovery systems are limited to real-time recovery of exhaust heat primarily for engine warm-up and fail to fully optimize exhaust heat utilization. This paper introduces a novel exhaust heat recovery system leveraging thermal battery technology, which utilizes phase change materials for both heat storage and reutilization. This innovation significantly minimizes the engine’s cold start duration and provides necessary heating for the cabin during start-up. Dynamic models and thermal management system models were constructed. Parameter optimization and calculations for essential components were conducted, and the fidelity of the simulation model was confirmed through experiments conducted under idle warm-up conditions. Four distinct operational modes for engine warm-up are proposed, and strategies for transitioning between these heating modes are established. A simulation analysis was performed across four varying operational scenarios: WLTC, NEDC, 40 km/h, and 80 km/h. The results indicated that the thermal battery-based exhaust heat recovery system notably reduces warm-up time and fuel consumption. In comparison to the cold start mode, the constant speed condition at 40 km/h showcased the most significant reduction in warm-up time, achieving an impressive 22.52% saving; the highest cumulative fuel consumption reduction was observed at a constant speed of 80 km/h, totaling 24.7%. This study offers theoretical foundations for further exploration of thermal management systems in new energy vehicles that incorporate heat storage and reutilization strategies utilizing thermal batteries.
