While every component must meet
the highest demands, it is integrat-
ed solutions that deliver the big-
gest ROI. They do this by reducing
costs, development time and effort,
and delivering the highest efficien-
cy, performance and integrability.
Other advantages are smaller di-
mensions, lower weight, reduced
interfaces, and improvements re-
garding electromagnetic radiation.
At AVL we are leading this new era
of mobility, thanks to our decades
of experience and our close rela-
tionships with the academic insti-
tutions driving knowledge in this
area. But it is our product and so-
lution portfolio that delivers real
results. Whether it’s the e-motor,
the transmission, the e-axle, or the
power electronics and software, we
turn knowledge into motion.
E-AXLES – A MODULAR,
LOW-COST APPROACH TO
E-MOBILITY
Our e-axles integrate the neces-
sary e-drive components – e-mo-
tor, transmission, and power elec-
tronics – and leave maximum space
for the battery. As an out-of-the-
box solution for passenger cars and
commercial vehicles their compact
design has additional advantages:
optimal integration into the avail-
able space, and weight reduction – a
bonus for improving driving range.
Our e-motor technology offers op-
tions for any application, including
up to 800 V applications. Our port-
folio includes axial flux motors, motors with direct oil cooling of the stator,
permanent magnet motors, asynchronous motors, or auxiliary units with-
out traction tasks.
Two-speed transmissions and various configurations of single-stage reduc-
tion gear boxes are included in our comprehensive product range of trans-
missions. Light, efficient, powerful, comfortable and economical, they help
to deliver the power where and when it’s needed the most.
None of this would be possible without the appropriate electrical, electronic
and software framework. We choose the best way to deliver the appropri-
ate power densities, such as our new developments into semiconductors,
including silicon carbide (SiC) or gallium nitride (GaN). These technolo-
gies offer increased efficiency and longer driving range.
Our modular and adaptable control software offers features like NVH-
optimized control, torque vectoring for e-axles and predictive driving func-
tions. Performance characteristics, alongside capacity, charging time and
cost, are optimized by our modular power electronics systems. They get the
best from every subcomponent and system, and include inverters for trac-
tion and auxiliary drives (including dual inverters) and DC/DC converters.
DELIVERING SUCCESS FOR ALL MARKETS
Our second generation high-performance high-speed e-axle for passen-
ger car has one of the highest power densities on the market, using solely
standard materials. It works with an 800 V characteristics, system and is
characterized by a maximum rotation speed of 30,000 rpm. The unit pro-
duces a total top performance of 500 kW and an axle torque of up to 6,000
Nm, made possible by innovations such as silicon carbide semiconductors
and direct-oil-cooled e-motors.
And it’s not all about passenger cars. Our reinvestment into R&D has en-
abled us to develop a compact but powerful high-density e-axle for com-
mercial applications. With flexible in-vehicle packaging that can be adjusted
to suit use cases for both battery electric and fuel cell electric applications,
from light to heavy-duty vehicles. To prove the feasibility of this system,
we are fitting it into our fuel cell demonstrator truck, which will be avail-
able to our customers soon.
