Résumé

Vehicle thermal management system (VTMS) is fundamental to ensure that electric vehicles components operate in their optimal temperature range to achieve high performances while preserving their lifetime. However, VTMS power consumption (pump, fan, electric heaters, heat pump, HVAC) affects negatively vehicle autonomy. Hence, an optimal trade off must be found. Automotive state of the art tends to oversize VTMS in order to cover extreme use cases, leading to increased investment costs, whilst affecting negatively vehicle payload and autonomy. This paper proposes a methodology to minimize the costs associated to component sizing for an electric vehicle thermal management architecture, returning as output the optimal cooling/heating capacity to be installed on the VTMS. An energy lump model is used for each component. Temperature constraints are fundamental in order to avoid premature wearing and prevent excessive heating/cooling demands. To solve the optimization problem, constraints and input parameters coming from a thermal management system designed by Volvo Group engineers for refuse handling is used. The input data accounts for cabin air conditioning, battery and power electronics thermal cooling/heating demand. Results show that compared to the usual approach, the optimization approach allows to dramatically decrease the heating/cooling capacity. For instance, the installed capacity to manage the power electronics cooling could be reduced by 50 %.
