The new thermal management concept for an electric vehicle is developed as part of the 1000kmPlus project. It builds on the original solution, which is extended by new thermal functions. The modifications made are aimed at meeting two aspects. Firstly, enhanced cooling capabilities for the newly available ultra-fast charging. Secondly, improved thermal efficiency and thus a reduction in overall energy consumption. The management of the thermal functions is represented by a state machine that contains three main sub-systems. These sub-systems are used for the management of the thermal circuit during vehicle driving, battery charging and battery pre-cooling. The state machine for thermal management is created in the MATLAB/Simulink scheme for easy implementation into the rapid prototyping platform Autobox 4 or MicroAutoBox II from dSPACE. The verification of the state machine was carried out in two steps. First, the basic functionality was verified in testing the Simulink application that contains a simple thermal circuit model. In the second step, the thermal functions were verified on the testbed. It is represented by a cooling testing circuit that contains LIN devices (valves and pumps) from the existing electrical vehicle. Furthermore, a graphical application was created for testing and monitoring thermal functions in the ControlDesk. This application allows you to monitor the current state of the thermal circuit, display key values and set the required valve positions and pump speeds.
