AVL Thermal Lab™

We help our customers develop highly efficient thermal management systems.
Thermal Testing solutions

As mobility transitions towards electrification, there is greater focus on the development of vehicle thermal management systems (VTMS). The temperature ranges for different components of an electrified propulsion system can differ greatly depending on operating and environmental conditions. This makes the development of the thermal system much more complex than in the past, and also increases the importance of an optimized VTMS. At AVL, we understand the needs and challenges of OEMs, Tiers, and institutes in this respect, and provide a wide portfolio of testing equipment to support you in optimizing the thermal layout of your propulsion system components and the complete system.  

For more than 25 years, we have intensively developed various conditioning systems and technologies, which are used in high-end engine test cells all over the world. This is the perfect foundation for understanding the increasing complexity of the cooling circuits of electrified propulsion systems in automotive applications. It is also the basis for understanding what our customers need from thermal management system development.

Thermal Management

A vehicle thermal management system (VTMS) has a significant effect on the energy efficiency of the entire vehicle and the durability of all components in the propulsion system, such as the battery and inverter. Highly efficient systems require extensive calibration and testing time at vehicle level, which has a huge impact on development costs and timing.

System and Subsystem Testing
Utilizing model-based testing, the AVL Thermal Lab™ supports you in optimizing the entire VTMS (all coolant circuits and the refrigerant cycle) in dynamic conditions. The unit under test (UUT) is the complete VTMS embedded in an emulated vehicle, while the environment is fully simulated. Unlike expensive vehicle tests in wind tunnels or on the road, you can test the entire system in the lab in realistic driving (WLTP, RDE, etc.) and ambient conditions, without vehicle prototypes and outside weather conditions.


Component Testing
Like for the complete thermal system, the model-based testing approach of the AVL Thermal Lab™ helps you optimize your thermal components without needing to having the entire VTMS available. Your unit under test (UUT) can be embedded in an emulated vehicle, while a hardware-in-the-loop (HiL) method fully simulates the rest of the thermal system and the environment.
