ation is a further key factor. For instance,
energy not only can be stored
in the battery itself; using predictive
strategies, it can also be put to efficient
use for conditioning purposes
in the thermal system,” Gerald Teuschl
explains.
EMERGING BATTERY TECHNOLOGIES
AND HIGH-END SIMULATION TOOLS
Now that BEVs are entering every
vehicle segment, the total height of
batteries proves to be a major factor
that can also help to improve
vehicle attributes. AVL’s 80-mm
batteries offer a host of advantages,
including benefits regarding installation
space and weight. Due to their
composition, they have a high volumetric
density and can very easily
be scaled in height in view of production
aspects (for further details,
see page 14).
“If you design batteries properly and
integrate them into the vehicle, you
can improve drivability – for example
torsional and longitudinal bending
vibrations. AVL additionally offers
NVH (Noise, Vibration, Harshness)
optimization for batteries, electric
machines, inverters and transmissions
and, additionally, for ancillary units
such as fans and pumps. This is done
predictively using simulation tools
such as AVL EXCITE™. Furthermore,
by employing AVL VSM™,
an extensive benchmark analysis
makes it possible to set up the entire
vehicle in the virtual world, broken
down into models and connected via
AVL Model.CONNECT™. Simulation
platforms such as AVL FIRE™
assist in calculating the thermal loads
of battery cells and designing them
proactively,” adds Gerald Teuschl.

KNOW-HOW AT COMPONENT
AND SYSTEM LEVEL
To address the increased future demand
for BEVs, and offer electric vehicles
with improved range, higher
output and faster charging processes
for shorter travelling times, detailed
knowledge not only on the component
and system level is required, but
also in view of project execution and
production. AVL offers the full bandwidth
of simulation, testing and engineering
capabilities to support customers
individually in their efforts to
meet their own objectives. Its ability
to act globally and to independently
access an extensive network of suppliers
makes AVL the perfect technology
partner – not only for developing
tomorrow’s drive technologies,
but also for making them ready for
series production. <
