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.
A VTMS has a significant impact 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 the vehicle level, which has a huge impact on development cost and time.
AVL ThermalLab™
The AVL ThermalLab™ assists in optimizing the entire VTMS process. Model-based tests simulate all coolant circuits under dynamic conditions. The unit under test (UUT), which is the complete VTMS, is embedded in an emulated vehicle, and the environment is fully simulated. Unlike costly wind tunnel or road tests, the AVL ThermalLab™ allows for comprehensive system testing in a laboratory setting, replicating realistic driving and environmental conditions, independent of vehicle prototypes and weather. Additionally, the AVL ThermalLab™ aids in optimizing thermal components, even without access to the entire VTMS. The UUT can be integrated into an emulated vehicle, while the remaining thermal system and environment are simulated using a hardware-in-the-loop (HiL) method.
AVL Conditioning Systems
The wide range of drivetrain concepts, from conventional to hybrid to fuel cell electric (FCEVs) and battery electric (BEVs), has increased the demand for testing that closely resembles real-world driving conditions. The thermal condition and environment of UUT have a significant impact on the real-driving results. Therefore, the simulation must be as precise as possible. To achieve this, high-performing media conditioning systems are essential. They must allow for adjustability to real in-vehicle conditions and guarantee high stability in both constant and dynamic operation. Additionally, they must be able to simulate extreme environmental conditions.
Batteries, fuel cells, e-motors, and e-axle solutions must operate safely and reliably in any environment. This can entail exposure to extreme temperatures and humidity, which are challenging to replicate on the test track or in real-world road tests. To address this, we developed the our climatic chambers. These innovative solutions safely and reliably simulate a wide range of harsh environmental conditions, providing high flexibility while minimizing system downtime. Their distinctive application-based design with pre-defined interfaces ensures seamless integration into existing testbeds.
We provide products, solutions, and systems for thermal and environmental conditioning to enable our customers to develop their products with the highest level of efficiency.”

At AVL, we develop e-axle solutions that can be easily installed without impacting the productivity of your engineering facility.
The AVL Customer Services organization consists of more than 700 service- and application engineers worldwide, operating from more than 50 locations. Our global footprint is your local benefit.
AVL ThermalLab™ tests the entire VTMS, including all coolant circuits and the refrigerant cycle, under dynamic conditions using model-based testing. The UUT is the complete VTMS embedded in an emulated vehicle while the environment is fully simulated. The entire system can be tested in the lab under realistic driving and ambient conditions.
Thermal conditions and environment of Units Under Test have strong impacts on real results in driving. For this reason, the thermal simulation must be as exact as possible – which can be achieved via deployment of high performing media conditioning systems.
Battery packs, modules and cells, fuel cells, e-motor and e-axle solutions must operate safely and reliably in any environment. This can include extreme temperatures and humidity, which cannot be reproduced on the test track or in real test scenarios on the road. This is why we developed the modular AVL Climate Chamber.
For several years, we have been at the forefront of developing advanced conditioning systems and technologies used in the world’s leading engine test cells. This experience gives us unparalleled insight into the evolving intricacies of cooling circuits within electrified propulsion systems for automotive applications.
You can benefit from our expertise and experience as we adeptly navigate the heightened pressures of the development phase. We prioritize customer satisfaction by meticulously managing project timelines and budgets. Our rigorous pre-validation of design and functionality prior to vehicle-level testing ensures seamless integration and optimal performance.
25 years of experience in the development of conditioning systems for automotive test systems form the basis for our in-depth understanding of cooling circuits in different electrified propulsion systems. It is also a good base for understanding our customers’ needs regarding thermal management system development.
