Development Strategies for Thermal Management Systems for Future Mobility

Josef Lapcik, Hanon Systems

The thermal management of electric vehicles is becoming increasingly important for achieving future development goals. In particular, the automotive industry is focusing on increasing vehicle efficiency by utilizing existing heat quantities in conjunction with the use of heat pump systems. This has a direct impact on the design and layout of thermal systems and the respective components. This publication presents the development of a simulative development platform for the design of thermal system components. In particular, differences between current development approach and approach utilizing new simulation environment will be explained. The development steps required to create the necessary sub models and their coupling will then be discussed. In an initial investigation, modern electric vehicles operating points and their influence on cooling module and heat exchanger design are considered. Comparison of selected results from new simulation platform and from original development approach is processed and discussed for new areas of improvement for system and components. Performance and durability-related data are collected to describe modern electric vehicle configuration impact on thermal management system. The article concludes with an outlook on how the development platform can be further improved and used for the development of thermal system components in the future.
