Zusammenfassung

The complexity of thermal management systems in battery electric vehicles continuously increases with system functionalities, customer demands and growing system performances. Grasping actual customer use-cases remains difficult and thus, most developments focus on the use of limited operation conditions, resulting in significant over- or underestimation and therefore respective system performances and customer feedback. This work presents a novel development and verification environment derived from autonomous driving development methodologies and its adaption for thermal management systems. We define a possible novel standard for thermal management scenarios and study on an exemplary scenario a possibility for comprehensive software and hardware co-development. We analyze necessary quality criteria and simulation requirements for the proposed novel environment. The discussion focuses on the utilization of the proposed approach, its advantages, and current drawbacks for co-development of software and hardware functionalities in thermal management systems. We conclude with an outlook toward the refinement of scenario generation, assessments of completeness and future improvements of the proposed environment.
