e-mobility 2 1
N O . 1 2 0 2 3
While every component must meet
the highest demands, it is integrated
solutions that deliver the biggest
ROI. They do this by reducing
costs, development time and effort,
and delivering the highest efficiency,
performance and integrability.
Other advantages are smaller dimensions,
lower weight, reduced
interfaces, and improvements regarding
electromagnetic radiation.
At AVL we are leading this new era
of mobility, thanks to our decades
of experience and our close relationships
with the academic institutions
driving knowledge in this
area. But it is our product and solution
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 necessary
e-drive components – e-motor,
transmission, and power electronics
– and leave maximum space
for the battery. As an out-of-thebox
solution for passenger cars and
commercial vehicles their compact
design has additional advantages:
optimal integration into the available
space, and weight reduction – a
bonus for improving driving range.
Our e-motor technology offers options
for any application, including
up to 800 V applications. Our portfolio
includes axial flux motors, motors with direct oil cooling of the stator,
permanent magnet motors, asynchronous motors, or auxiliary units without
traction tasks.
Two-speed transmissions and various configurations of single-stage reduction
gear boxes are included in our comprehensive product range of transmissions.
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 appropriate
power densities, such as our new developments into semiconductors,
including silicon carbide (SiC) or gallium nitride (GaN). These technologies
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 functions.
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 traction
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 passenger
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 produces
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 enabled
us to develop a compact but powerful high-density e-axle for commercial
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 available
to our customers soon.
