A new generation of battery packs with a recyclable epoxy SMC casing
Th e old fl oor structure was replaced by an
aluminium sandwich plate developed by
the youngest consortium member Minth.
With this concept, the group was able to get
rid of additional side-mounted deformation
elements and use the freed space for batt ery
cells instead. Using Forward Engineering's
BEV fl oor structure development tool, the
Pure Performance Batt ery was confi gured
and validated so that an improved impact
behaviour of the sandwich fl oor could be
achieved and the space required for the
module assembly was reduced. In this way,
the capacity could be increased by 10 kWh
to a total of 75 kWh with approximately the
same external dimensions of the batt ery
pack. Th us, the aluminium sandwich plate
not only improves performance in terms of
bott om impact, but also plays a key role in
the semi-integral vehicle concept.
Modular design and epoxy SMC
housing boost performance
Th e new Pure Performance Batt ery can be
for example 2.1 m long and 1.58 m wide
or other dimensions, with a maximum
height between 0.15 and 0.22 m, enabling
a variety of vehicle architectures. In terms
of ergonomic design, it competes with
other high-end solutions, but surpasses
them in terms of performance. Th e
modular series design of the batt ery also
allows fl exible adjustment of the number
of modules. Th e supercell concept based
on LION Smart's LIGHT Batt ery enables
a calculated fast charging result of around
13 minutes for a charging power constantly
above 200 kW (10 to 80% SOC).
Th e system is currently being optimized
in this respect to achieve a charging time
of less than 10 minutes in the future.
Th e glass fi bre-reinforced epoxy SMC
cover from Lorenz Kunststofft echnik not
only stands out for its low weight, but at
the same time provides a very high safety
potential in terms of fi re resistance and
crash behaviour. It withstood all the relevant
fi re-related test set-ups, including
thermal runaway tests conducted at a
testing facility in southern Germany. In
addition, all concerns regarding the EMI
shielding performance of the glass fi bre
composites were tackled with a broad maFocus
About
the consortium: joint commitment to the future of electromobility
In 2019, several companies from the automotive and mechanical engineering
industries, as well as from the chemical and plastics sectors, organized themselves
with the common goal of developing a battery concept for fully-electric
vehicles that is suitable for series production. During the development, a new
partner joined the consortium. As the European headquarters of the Chinese
Minth Group, Minth GmbH, based in Unterschleißheim, Bavaria, now also
supports the battery consortium, which consists of Lorenz Kunststofftechnik
GmbH, Vestaro GmbH, Forward Engineering GmbH, Evonik Resource Effi ciency
GmbH and LION Smart GmbH.

terial toolbox and validated under OEM
requirements. Th e process benefi ts were
verifi ed by manufacturing several complex
demonstrator geometries.
During these trials, cycle times of around
3 minutes were achieved, suggesting a
high cost-saving potential.
Resource effi ciency thanks
to recycling system and
" mix-and-match " service
Th e new generation of high-voltage battery
packs has not only been improved in
terms of performance. Future-proof solutions
should be sustainable, this is why
the consortium also addressed this topic
with its developments. For example, the
cover can be disassembled by undoing
several screw connections to enable easy
access to the batt ery modules and peripheral
equipment. Unlike bonded systems,
the Pure Performance Batt ery allows
individual components to be replaced
and repaired. Th e epoxy SMC batt ery
cover itself can be recycled by Lorenz
Kunststofft echnik and aft erwards reused
in new composite parts.
Overall, the consortium partners have
once again learned a lot from each other
during the development process of the
new-generation batt ery pack in order to
be able to supply customers with an allround
fi nished batt ery pack. Given the
dynamics of the industry, all project partners
are prepared to handle requests from
potential customers that deviate from the
basic model and to off er a collaborative
" mix-and-match " service. Th is off er presents
a great opportunity for applications
as the consortium makes it possible to
address a company on a topic and benefi t
from the performance and know-how of
the other members.
