ANALYSIS OF EMC RESULTS UNDER REAL-DRIVING-CONDITIONS
The behavior of components such as the e-drive changes depending on
different uses. This forces the testing operator to dodge steady state mea-
surements for real driving conditions. And EMC measurements with fixed
operating points, as in conventional internal combustion engine vehicles,
do not show the same effects as in the electrified vehicle.
Additionally, the EMC test setup comprises of the device under test (DUT),
the load simulation, conditioning systems and the EMC measurement
hardware and chamber. All these components have separate automation
and/or control systems for their operation, and must be interconnected
to measure their dependency to each other.
To tackle this we have collaborated with Rohde & Schwarz, a provider
of measuring and testing systems, on an exclusive solution for automated
EMC data analysis. The system works under real operating conditions of
an electric vehicle or any of its components.
AVL PUMA 2™ automation drives the test cycle and stores the measured
data, in sync with the R&S®ELEKTRA test software, which exchanges
information between the testbed and the EMC measurement equipment.

AVL Test Systems
for Electromagnetic
Conformity (EMC)
EMC E-MOTOR TEST SYSTEMS
The AVL E-Motor TS™ EMC –
fixed provides the highest perfor-
mance and EMC capabilities. Cus-
tomers do not have to compromise
between the mechanical and the
EMC performance of the test facility.
The AVL E-Motor TS™ EMC –
mobile solution performs high-
speed EMC testing under load in
existing EMC chambers without
major modifications. The mobility
of the system allows complete pre-
setup outside and transfer into the
chamber, resulting in high efficiency.
EMC E-AXLE TEST SYSTEMS
The AVL E-Axle TS™ EMC is
an extension of the fixed E-Motor
EMC test system. This scalable so-
lution can be extended to all perfor-
mance classes of AVL’s dyno port-
folio, reaching up to 5,000 Nm and
3,500 rpm.
EMC VEHICLE TEST SYSTEMS
Integrable into both anechoic and
shielded EMC chambers, AVL
ROADSIM EMC™ is a chassis
dynamometer that supports EMC
testing for everything from passen-
ger cars to heavy trucks. It complies
with most international regulations
(CISPR 12 and 25, ISO 11452,
GBT 18387-2008 and ECE-R10).
AVL CONCERTO™ post-pro-
cesses the measured data automat-
ically, delivering a full test report
according to pre-defined pass and
fail criteria. It supports automated
testing with simulation of real driv-
ing conditions while covering typi-
cal automotive standards. The ben-
efits include:
• Complete EMC results under real
driving conditions
• Reduced complexity of EMC
measurement procedure for com-
ponents and vehicles
• All test specifications and exam-
inations can be carried out de-
pending on the different DUT
and EMC parameters
• Synchronization of EMC mea-
surement and DUT operating-
data, which shows the dependen-
cy of the operating state and EMC
data, and the behavior of EMC
parameters depending on the op-
erating variables of the DUT
• Repetitive and deterministic test
procedures allow for fast compar-
isons between testing cycles and
their visualizations
• Individual monitoring criteria can
be defined for any channels. Devi-
ations and violations of tolerance
bands are evaluated automatically
Our EMC test solutions guarantee
that the DUT is the only focus of
each EMC measurement. They also
reduce test setup complexity to en-
sure that testing is safe, precise and
as time efficient as possible. This
empowers our customers in their
e-mission. �����������������������������������������������������������������������������������������������������������������������������������������������
An increasing number of electrical and electronic (EE) subsystems
are being integrated into vehicles. Operating high-performance electric
propulsion under all conditions and in close proximity to sensitive com-
munication systems is one of the most significant hurdles the automotive
industry must overcome. EMC measurement should therefore be consid-
ered early in development.
At AVL we have continuously expanded our portfolio of EMC test systems
from component level to the complete vehicle, and always compliant with
EMC standards. The three major test areas are e-motor, e-axle and vehicle.
