AVL Climatic Chamber

Application-driven solution for best-in-class thermal development.

Climatic chambers are the solution for simulating extreme environmental conditions
for batteries, fuel cells, e-motors and e-axles in the testing environment.

rendering climatic chambe

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.

Components must be able to withstand a wide range of environmental conditions. They must be able to operate in very cold environments, such as arctic winters, as well as in very hot atmospheres, such as painting chambers. In addition, humidity can have a major impact on performance, material stress, and service life. Furthermore, lifetime testing can be accelerated by creating thermal shocks. The climate chamber allows all the necessary tests to be performed to meet current standards.

Battery Destruction During the Test

The AVL safety system is developed according to the customer's needs.

No Standard Solution for Test Area Requirements

Customized adaptations of standard products are possible.

Battery Testing Is a New and Growing Application

AVL is an experienced and reliable partner for test systems.


  • Operating temperature inside the chamber:
    • Temperature gradient for heating and cooling according to IEC 60068-3-5
    • Average value, measured in supply air, without thermal load
    • Thermal compensation values depending on power type
  • Walk-in chamber size: Due to the different types of test equipment, the chamber size has optimal dimensions.
  • Cell test chamber size: Optimized solutions for cell testbeds result in balanced chamber sizes.
  • Insulation material: Depending on the safety level, polyurethane or mineral wool insulation can be chosen.
  • Cooling water flow: Domestic water connection reduces the need for cooling power, thus reducing the energy consumption of the chiller.
  • Flooding option: Especially when testing battery prototypes, critical thermal problems can occur with the device under test. Flooding the chambers protects the surrounding building from major damage.
  • Safety system: AVL offers a well-designed safety system to achieve Hazard Level 4 or 6 for testbeds.

  • Safety system: AVL offers a well-designed safety system to achieve Hazard Level 4 or 6 for testbeds.
  • Outdoor installation: A complete thermal test stand can be installed in a container.

AVL Gas Sampling Unit

The AVL Gas Sampling Unit is an outstanding safety device, which measures and analyses the gas composition while battery testing inside the test chamber.

media conditioning
Conditioning Systems

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.

AVL ThermalLab™

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.

Mobility of Tomorrow: Are Affordability and CO₂ Reduction in Conflict?

As a global society, we are pushing hard to achieve a transformation to net-zero-CO₂ but without loosing energy security and our current living standards. The transformation in the mobility will come at cost, which endangers affordable individual mobility in the future. Doing nothing, however, will generate even higher costs.
