AVL Battery Cell TS™ ACORA

Battery cell test system with direct cooling technology.
rendering acora

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.

High Test Requirement

New chemistries/ material pairings need to be tested in the quest for greater range and lifetime.

High Cooling Cost

Due to the need of energy for cooling in different temperature regions, the energy costs increase.

Disadvantages of Temperature Testing

Long stabilization times during cooling and heating up.

Different UUT Requirements

It must be possible to test different cell types (prismatic, pouch, cylindric) in different sizes.

General Cost Pressure

The need to do as much as possible in less and less time leads to time and cost pressures.


ACORA as solution acts as the missing link between cell R&D and production testing. R&D testing equipment with AVL’s high current cell tester offers high charging and discharging currents for cell validation, which can now be utilized in a production testing environment. The water-cooling approach adds a very accurate, high dynamic temperature control. AVL designs its safety systems based on a huge data base of different cell types. This enables us to scale safety measures along with customer needs in regard to Hazard Levels (HL), while keeping the overall safety in check.

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.

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.
