BRIEFS
SPOTLIGHT: EV POWER
ELECTRONICS
Pressure sensors
Melexis (Tessenderlo,
Belgium) launched
the MLX90830 pressure
sensor. The sensor
reportedly delivers
a proportional
analog output signal
that can be integrated
into the latest EV
thermal- management
systems. The
MLX90830 features
Melexis' Triphibian
technology, which
allows the sensor to
provide accurate measurements considerably above 5 bar
(72.5 psi) but also while in contact with liquid. The sensor
is equipped with protective mechanisms against overvoltage
(above +40 V) and reverse voltage (below -40 V)
which makes it usable for both automotive and commercial-truck
applications. Melexis states that compared to
existing non-MEMS-based designs, the MLX90830 provides
elevated accuracy, helping to optimize the efficiency
of the vehicle's thermal-management systems and enabling
increased range.

Foldable battery gasket
Freudenberg Sealing
Technologies (Plymouth,
Michigan) offers a new
foldable gasket for EVs.
Freudenberg states that
the gasket contributes to
the reliability and longevity
of battery systems.
The gasket consists of a segmented aluminum carrier with
multiple sealing profiles on the outer edge. These reportedly
provide strength while also integrating plastic retention fixtures.
These are used to attach the gasket to the battery
housing cover. The carrier segments are interconnected with a
continuous sealing profile that is flexible so it can compensate
for manufacturing tolerances in the housing. Freudenberg
claims the foldable gasket helps make the battery system
more reliable and durable and that its simple disassembly also
makes it easy to service and repair the battery.

SPOTLIGHT: SOFTWARE
Design tools
Power Integrations (San Jose, California) (NASDAQ:
POWI) and SnapMagic (San Francisco, California) announced
that PI Expert, Power Integrations' online design
tool, now features schematic and netlist export made possible
by SnapMagic's new schematic export technology.
Based on specifications input by the user, PI Expert automatically
generates a complete power supply schematic
utilizing Power Integrations' power-conversion ICs, including
a custom magnetics design. Previously, the automated
tool flow covered everything up to full circuit optimization,
but required manual transcription into a CAD package to
facilitate simulations and physical layout. The new export
capability ensures a fast and seamless transfer of the design,
including symbols, footprints, 3D models and electrical
netlist into one of four popular PCB CAD tools.

Intelligent tire management
ZF (Friedrichshafen, Germany)
and Goodyear (Akron, Ohio)
announced the integration of
tire intelligence technologies
with vehicle motion-control
software. The collaboration
delivers Goodyear SightLine, a
suite of tire-intelligence technologies,
into the ZF cubiX, a scalable vehicle motion-control
software that coordinates all dimensions of vehicle dynamics.
This provides further tire and road data into the chassis system
and enables an improved driving experience with better comfort,
control and efficiency, the companies said. Additionally, the
synergy between Goodyear SightLine and cubiX capabilities can
provide enhanced vehicle responsiveness, more direct and linear
steering, improved turn-in response, increased stability, reduced
controller workload and minimized intrusive interventions.
