AVL Direct Cooling Technology

Research and development testing for highly accurate measurements.

ACORA  Active Cooling Rack provides a more efficient way of temperature conditioning cells in a test environment compared to conventional climate/temperature chambers. With ACORA, cells are placed in water-cooled cold plates to achieve the required temperature conditions faster and more accurately. By integrating a robotic solution, ACORA can be operated fully automatically. In addition, it offers the possibility of testing over the entire temperature range under full load conditions.

OEMs, battery, and cell suppliers must continuously develop and test new battery cells for the evolving automotive market. For battery electric vehicles mileage range is key, making the capacity of battery cells and packs a crucial factor. Besides capacity, power and life cycle analysis are central parameters in battery development. With cell testing, there are simple units under test (UUTs) with a high demand on testing flexibility in process and methodology – compared to battery packs which need a different test system.

AVL Climatic Chamber

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.

AVL Conditioning Systems
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.

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.
