Battery benchmarking
A comprehensive analysis of the battery system down to each individual cell
is providing detailed results and measurements for the latest line-up of BEVs
New materials, technologies,
processes and production
methods for battery systems that
have to meet customer demands for
inexpensive large-scale electric
mobility production, present a
constant source of new challenges
to development departments.
To remain ahead of the game,
companies must obtain a
comparative analysis of the current
state of technology and the related
engineering methodology. However,
performing an analysis of the
technical battery functions, its
performance and the way in which
the system is integrated into the
vehicle is challenging both in terms
of cost and time.
Having an independent survey
of such information conducted by
experts in this field can deliver major
advantages. That is why AVL,
experts in development, testing and
simulation of powertrain systems,
o ers a comprehensive benchmark
analysis, in which it examines and
compares the competitiveness of
series batteries based on more than
240 benchmark criteria.
AVL Series Battery Benchmarking
is not simply a teardown of a battery
it goes into extreme technical depth,
o ers modularity and easily
accessible information. Firstly,
vehicle measurements are
conducted that include an analysis
of the operating strategy and control
systems. The battery pack is then
subjected to a detailed
measurement on the testbed. Based
on this, AVL experts examine the
thermal, electrical and mechanical
subsystem. In addition to a detailed
safety assessment at pack and cell
level, the production process and
cost structure undergo an analysis
on the basis of a detailed
specification list.
As well as this, the benchmarking
program’s extensive catalog of
AVL’s Series Battery Benchmarking examines technical battery functions at a pack and cell level
criteria includes a selection of
important engineering tasks such
as condensate handling or EMC.
As an independent development
and service provider catering to the
automotive industry, AVL
benchmarks up to four innovative
vehicles a year to guarantee
outstanding depth of high-quality
information and a high level of
accuracy. AVL experts regularly
optimize the reports in close detail,
not only where technology and
development methodology are
concerned but also regarding the
manner in which the information

is presented to o er interested
parties comparable battery
attributes that also fit into an
a ordable budget. Customer
workshops are o ered, where these
benchmarking results are presented
and discussed by expert AVL
representatives around the world.
Latest results are available from
luxury SUVs such as the Audi e-tron
quattro and Jaguar I-Pace as well as
an a ordable family vehicle from
Korea – the Hyundai Kona. To
particularly address solutions from
a newcomer in China, AVL analyzed
the NIO ES8. AVL experts test and
rate the battery systems in a variety
of scenarios, and even include a
detailed cost analysis. In AVL’s
benchmark reports it presents how
well the vehicles compete with each
other, and also how they compare to
major rivals, for example, Tesla
Model X or Tesla Model 3. In 2020
AVL is going to analyze the next big
step in technology with the Porsche
Taycan, and in cost optimization for
the Volkswagen ID.3.
