Automotive Technology Battery Test Laboratory

Increasing shortage of resources, growing populations, environmental pollution and high commodity prices lead to the continually increasing importance of electromobility both for the industry and the private user. Before batteries can be used in a vehicle, they must pass a series of tests:

Electromagnetic compatibility and cycling test
In addition to interference-free interaction with the on-board electronics (EMC electromagnetic compatibility), the battery must also be reliable, chargeable and robust.

Temperature and climate change test
Electrically-driven vehicles should subject to the same conditions as petrol-driven vehicles. Changing weather conditions, rain and strong temperature fluctuations are simulated during temperature and climate change testing.

Corrosion and noxious gas test
This extends the spectrum by corrosion and noxious gas testing where the battery is subject to an artificial aging process. Salt as it occurs in sea air for example, or gritting can attack the housing and therefore impair the performance and safety of the battery. 

Vibration and shock test
Long before they are used, batteries are subject to to constant vibrations and knocks - for example, during transport and loading. Folowing installation in the vehicle, vibrations from the road surface and knocks can be expected such as those caused by driving over cobblestones or the curb.

All of these influences should not impair the performance or service life of the battery. These relevant parameters are tested and evaluated meticulously under the strictest safety conditions in our battery test laboratory. The most modern test equipment enables precise setting of the influential factors according to test specifications and acquires the measured data at any time with the highest precision in order to generate qualified test results according to your requirements.
