Thermal Management Service on Test Benches

Thermal management is a key topic in vehicle development that is taken into account in the development process right from the start. Valuable development steps can be taken at an early stage on a TC5:E5hermomanagement system test bench. By integrating calculation models and simulators/emulators, qualitative statements on systems, components and control strategies for cooling, heating and refrigeration circuits could be made at an early stage of development (without a vehicle). In addition, early testing of operating strategies is possible. In further phases of development (including series production support), problems can be reproduced and causes investigated in a reproducible environment.

• Dynamic load cases on the thermal management system test bench and sharpening of simulations
• Function and control development on thermal management
• HIL with vehicle control unit and real cooling and refrigerant circuits
• Innovative heat pump refrigeration cycles and concepts - analysis and optimization
• Characteristic diagrams for coolant circuit control - Curve diagrams for actuator control
• Refrigerant circuit system optimization - basic investigations and system adjustment
• Investigation of system instability/assessment of critical load cases
• Investigation regarding refrigerant displacements in the system
• Safeguarding investigations of component requirements within the overall system
• Oil circulation ratio hedges/oil fill rate surveys and recommendations.
• Standard measuring programs for safeguarding e.g. SAE matrix, LCCP etc.
• Refrigerant charging quantity regulations
