INTRODUCING AI
FOR BATTERY DESIGN
CONFIDENCE
As the complexity and popularity
of e-mobility increases, the
demands placed on the battery are
greater than ever. This crucial system
must therefore perform and
behave with utmost reliability.
Even though today’s batteries deliver
more than ever before, their
development and production are
subject to uncertainties and unpredictable
issues such as production
tolerances. This can lead to a high
level of costly production scrap.
Battery development is a vibrating
space of captivating topics, such as
cell characterization, cell aging, fleet
battery modelling, and optimization
of cell material and geometry.
When optimizing cell material and
geometry, there are risks of deviations
in terms of capacity, aging,
lifetime, or performance that can
affect the battery’s target values, but
which are difficult to manage.
At AVL we’re using AI to tackle
this problem.
DESIGNING THE BEST CELL
IN THE WORLD
Cell design comes with myriad
considerations,
from choosing the right
chemical composition for the best
performance, to the exact
anode
thickness and layout, all to achieve
the desired KPIs. Input uncertainties
(such as tolerances, environmental
or usage factors) that are
often difficult to consider, make optimizing
the cell composition complex
and time consuming. That is
why we have developed the Robustness
Optimizer, as part of AVL
CAMEO 5™ for Battery.
This AI algorithm takes any difficult
or uncertain values – such as tolerances,
environmental or usage factors
– and integrates them into the
optimization workflow. The result is
increased certainty in areas
such as:
• Optimal trade-offs between battery
KPIs such as cell capacity,
fast charging capability and losses
• Production tolerance consideration
and identification in cell
composition design
• Strongly reduce production scrap
and save money
With the Robustness Optimizer, we
are leading the charge for optimal
cell design. Turning uncertainty on
its head, the unpredictable can now
be added to the equation. �
