New measurement tools for powertrain NVH
As modern propulsion systems
become increasingly complex,
vehicle manufacturers are not just
trying to reduce the noise emitted
by the powertrain – they want to
engineer it. This requires that the
NVH measurement and analysis
toolbox be fl exible, effi cient and
effective. Kistler’s answer to this
trend is KiNova: measurement
and analysis tools specifi cally
designed for powertrain NVH.
KiNova has been developed
to meet the application-oriented
needs of NVH engineers, wherever
they operate. The portable
hardware, KiNova Lite, is ideal
for on-the-spot measurements,
while the extendable KiNova Pro
solution, with 16+ measuring
channels, can be deployed in
the lab or for mobile use. These
products are complemented
by standard KiSuite software
packages providing optimal
support in the different phases of
powertrain development. Tools
such as hammer impact testing
(KiSuite HITS), order
tracking (KiSuite
NVH) and source
contribution analysis
(KiSuite SCA) are
easily confi gured
for use with multiple
sensor types.
Whether
in relation to
conventional, hybrid
or pure-electric
propulsion systems, KiNova
can make a major contribution
in NVH by supporting the
development of advanced
propulsion systems that not only
meet legislative regulations, but
also provide the right sound and
comfort experience.

High-temperature resistant battery housing
Lithium-ion batteries are an
essential part of the development
of electromobility. They offer
impressive benefi ts such as
suitability for powering emissionfree
drives, high effi ciency and low
self-discharge rates. However,
their design requires special fi re
protection measures during use.
In the event of a failure, Li-ion
batteries can reach temperatures of
more than 1,000°C (1,832°F). This
overheating can lead to fi re. Secure
casing of the batteries helps to keep
the temperature under control and
ensure safety for both people and
machines. Thanks to Thermamax’s
experience with high-temperature
insulation, the company can
contribute to the operational safety
of battery systems.
The Tmax-Battery Housing
protects the environment against
the effects of thermal runaway, and
the battery against the risks of high
ambient temperatures.
To protect Li-ion batteries against
fi re, it is not enough to just develop
high-temperature insulation.
Instead, the temperature must be
permanently monitored. This is
why the Tmax-Battery Housing has
thermal management with highperformance
cooling.
The insulated housing reliably
protects the battery from
external infl uences,
such as water, extreme
temperatures, dust or
vibrations. If there is
a strong increase
in pressure, the
safety valve opens
and prevents a
possible explosion.
The valve automatically
closes when the
pressure drops.
The benefi ts of the
technology include
maximum safety in case of
accident, optimal temperature
control (which provides extended
battery range and longer life cycle)
and operational safety.
KiNova Pro – Advanced, fl exible and scalable
system, along with KiSuite apps forms a sophisticated
environment for the most demanding NVH
measurement and analysis tasks
KiNova Lite –
Powerful, compact
and highly portable
system, equipped
with KiSuite apps to
support characterizing
and understanding
powertrain NVH
problems
