E ciency in electric and hybrid vehicle development
Effi ciency is a key driver in
electromobility development.
In electric and hybrid vehicles,
pushing components as close as
possible to their performance limit
is the key to effi ciency. Sintered
power electronics provides the
optimal solution for this.
Power electronic modules are
responsible for power distribution
and energy management in
electric and hybrid vehicles.
Yet the demands that the
automotive industry places on
power electronics pose particular
challenges in terms of longterm
stability and reliability. To
achieve these high standards,
sintering represents an optimal
solution. With the high precision
and long service life of sintered
components in the power chip,
operation in temperature ranges
over 200°C and close to the load
limits are possible. This results in
signifi cantly higher performance

At the same time, the higher

new possibilities for the use of
future-oriented material systems
based on SiC and GaN. Specially
developed sinterable temperature
sensors in SMD-format support
innovative production methods
and inspire more compact designs.
Further goals include more
effi cient production processes that
make it possible, for example, to
assemble all components during
one process step. This calls
for state-of-the-art assembly
and connection technology.
Heraeus offers interdisciplinary
development expertise in the areas
of materials, integrated circuit and
mounting technologies, housing
technology, and integration.

assessments. During these
On-road evaluations provide
evaluations, vehicle interaction
insights on equipment durability
with charging stations and power
and how systems function in
grids is assessed for competitor
different weather conditions.
These assessments also provide
insight on how often EVSE may be
blocked by a vehicle with an internal
combustion engine, and costs to
charge, in terms of time.
When conducting on-road
testing, several elements must be
considered in order to build a robust
test plan.
For example: altitude and
elevation may impact systems and
operating power; certain weather
conditions, including temperature
and precipitation, can impact power
supply, duration, mileage and range;
certain settings present numerous
charging options closer together,
while others have fewer – this can
impact battery life and reliability;
knowing what type of power grids
are available will impact testing
needs and data; the desired market
to enter will impact the above
considerations when developing
such a plan.
Working with an experienced,
global third-party lab can be critical
to a successful assessment. Intertek
offers on-road assessment solutions
to the industry, with a global
network of labs dedicated to electric
vehicle testing. The company’s
on-road testing services are fully
complimented by in-lab testing
services to provide end-to-end
peace of mind via both controlled
and real-world environments.
