Model-based development of a holistic thermal management system for an electric car with a high temperature fuel cell range extender

In the course of the project ""Regional Eco Mobility 2030"" (REM2030) energy-efficient concepts for the regional mobility of the future are investigated. An AUDI A1 Sportback body is used as technology demonstrator with an entirely electric powertrain, completed to a serial hybrid by a fuel cell range extender. A methanol reformer provides hydrogen for a high temperature fuel cell. Main focus in this paper is the thermal management system of the car, which has to deal with different temperature levels and has to be designed under the aspects of being emission-free and energy-efficient. The model-based development of such a system using Modelica is described comprising a conception, simulation and testing phase.
