TECHNICAL INNOVATIONS
Designers are
changing their
strategies to
cope with the
expanding
growth of
software in
commercial
vehicles.
powertrain software that can respond
to oil spills on roadways, for example.
Charging forward
Technologists working on electric vehicles
(EVs) also are dealing with rising
complexity. There is a range of standards
for charging, posing challenges to ensure
that a base design can operate with
different charging stations. Newer chargers
may include bidirectional charging
and technologies that let drivers automatically
pay when they plug in.
Andreas Aumann, VP of strategic
product management for accessories at
BMW Group, noted that standards like
ISO 15118 for vehicle-to-grid communication
for EV charging are " the right way
to go. " He added that BMW is confident
that half its sales will be EVs by 2030.
As the charging infrastructure grows,
much of the transportation industry's
work will be to eliminate software glitches.
Most hardware issues have been resolved,
but many software issues remain,
according to Accenture's Sabine Hug,
manager of EV charging. She described
problems such as some systems that ask
for information before vehicles are
plugged in, while others reverse those
steps. That's extremely confusing for
users. Conformance testing by thirdparty
organizations is needed to avoid
this type of issue, but it's only one step
in the testing process.
" Conformance tests only cover one
software standard, not the entire chain, "
Hug said. " We need end-to-end tests.
Things get very complex when standards
add new sequences and features
like bidirectional transfers. "
