Form, function and flexibility
for cost-optimized integration
Battery development at AVL has multiple goals. The focus is on maximizing
performance, durability and safety, as well as minimizing development,
production and assembly costs. Safety is one basic requirement that
must be guaranteed in every phase of the lifecycle. There are also typical
conflicts of objective, such as between energy content and weight/volume,
or between power density and durability. Our approach at AVL is to balance
out these conflicts as well as possible, in accordance with the demands
placed on us, and in doing so to manage the cost factor.
DEVELOPMENT METHODS
In order to ensure that our developments
are of the highest quality –
despite the broad range of objectives
with some seemingly conflicting
requirements – we use established
processes. These are based
on the current ASPICE standards
in the automotive industry, which
originally came from the software
area and have been expanded for
full systems – including mechanics,
hardware and electronics. In battery
development, we combine our
ASPICE-compliant
approach with
model-based system development,
with more than 60 pre-defined
battery
functions. This gives us greater
efficiency in the development process
and allows us to launch our
battery products faster and more
cost-efficiently.
MODEL-BASED SYSTEMS
ENGINEERING (MBSE)
The holistic MBSE approach that
we follow guarantees a deep understanding
of all aspects of battery development
and its interactions. As
such, we are in a position to seize
tasks from all perspectives and to
approach them from different directions.
Our overarching system
model considers all requirements
and specifications when defining
the framework for the respective
project. As a reference, as a “single
point of truth”, it provides us with
data for the simulation and for creating
analyses. It is the foundation
for every new product and the ensuing
development of derivatives.
BATTERY DVP
In order to achieve valid test statements,
an appropriate Design Verification
and Validation Plan (DVP)
is required. Our battery DVP conforms
to all global standards and
covers the required test criteria.
This coverage can be optimized using
the AVL Load Matrix™ method,
in order to achieve a release recommendation
in a cost-efficient and
time-saving manner, particularly
for product variants.
