In-Field Use
and Ageing
For a long, powerful battery life
For electric vehicle customers, value retention depends largely on the lifespan
of the battery
system. Assembly and structure play an important role here – but not the only role. Intelligent
handling is also key to the lifecycle. We take a holistic approach here: we consider the entire system
at every development step, ensuring that the complete vehicle architecture supports the longest
and most powerful battery lifecycle possible. Furthermore, we also consider ease of service,
recycling opportunities, and second-life values when not suitable for automobile applications.
At AVL, we work with an integrated and open development platform (IODP), which connects
all the elements in the vehicle development process. In doing so, we also achieve a free flow of
data along a battery’s entire value chain and, with the help of the knowledge gained from the
data, can cover many application scenarios for value creation. We help you exhaust the full
potential of the latest battery technology by, for example, monitoring the battery’s performance
throughout its usage or monitoring the performance of aged batteries in in-field use. All our
approaches follow the frontloading principle of early embedding in the development process.

“ focus: Which are the key topics
in lifetime optimization
of a battery?
Brade: Smart engineering and
handling of a battery require
smooth cooperation of many
tools, solutions, and engineering
disciplines along
the value chain of a battery.
At AVL, we are excited to be
a part of this inspiring journey
towards a truly sustainable
and intelligent future.

GREATER EFFICIENCY
THROUGH DATA INTELLIGENCE
Large quantities of data are generated
when developing battery systems.
To manage, evaluate and use this data,
we use intelligent data management,
which allows us to rapidly
and economically reuse the data
for follow-up developments. By
linking measurement data with corresponding
metadata, we can further
increase efficiency.
We have designed Device.CONNECT
™ specifically for tests with
fleets of vehicles. The solution connects
the vehicles to the data center
via a box and an app. Vehicle data
and driver feedback are transferred
there and automatically analyzed
in real time. The system identifies
special events and automatically calculates
key performance indicators.
All trips can also be systematically
searched for and analyzed, in order
to respond to detailed queries
in seconds.
With Device.CONNECT™,
changes to the ECU, right through
to full updates, can be rolled out
“over-the-air” to all connected vehicles.
This option significantly reduces
development cycles and work
times in fleet management, thus saving
money. Automated evaluations
also increase efficiency by considerably
reducing the reporting effort.
Constantly monitoring the vehicle
fleet also makes it possible to intervene
immediately, which also saves
mileage, time and money.
OPTMIMIZED BATTERY
MANAGEMENT IN USE
We use data from the development
and test phase to create self-learning
modules, which improve the
predicted range of the vehicles and
monitor battery ageing during the
operating phase. Our solutions can
