Several thousand battery cells can be aged and analyzed simultaneously
in the laboratories.
Weiss Technik has supplied various
high-end test benches, climate chambers
and temperature test chamber
nisms of battery cells and systems as well as
power electronic components and systems.
An investment of over 100 million euros has
created a unique, interdisciplinary research
center that can model, measure and optimize
the service life and reliability of batteries,
The CARL: Center for Ageing, Reliability
and Lifetime Prediction of Electrochemical
and Power Electronic Systems was opened
at the ISEA Institute at RWTH Aachen University
in 2023. More than 120 researchers
are analyzing the aging and failure mechafrom
the molecular level of a battery to the
chemical processes involved in charging and
discharging under various influencing factors
to the behaviour in coupled systems. Several
thousand battery cells can be aged and
analyzed simultaneously in the laboratories.
Weiss Technik has supplied various
high-end test benches, climate chambers
and temperature test chambers for environmental
tests and continuous cycling for
CARL. They are used in 40 containerized
test cells and other laboratories, primarily
for checking model assumptions and verifying
measurement results.
Stephan Bihn heads the Battery System
Technology and Vehicle Integration department
at the Chair of Electrochemical Energy
Conversion and Storage Systems Technology.
He describes how the collaboration between
materials scientists, chemists, physicists,
mathematicians and electrical and
mechanical engineers is rapidly increasing
our understanding of the system. Whether
Prof. Figgemeier‘s group is analyzing interface
effects at the material level, Prof. Sauer‘s
department is modeling the behavior
of the battery cell or Prof. de Doncker is developing
a new charger or a new drive - the
knowledge is in-house. The connection to
Münster University, the Helmholtz Institute
and the Fraunhofer FFB is particularly close.
Weiss Technik recently supplied a drying
room for the FFB in Münster and is currently
building a second one.
At CARL, weisstechnik‘s devices are
used in a variety of ways to achieve the goals
set: optimal battery systems for stationary
and mobile applications - from the initial
design, selection of the most suitable battery
cells and electrical dimensioning, the
battery management system, thermal management,
detailed CAD designs through to
physical and functional integration into the
application and suitable tests.
