Cars & boats go electric! – The Challenges Facing Electronics Production


The world is moving – and becoming more
electronic all the time. Not only on the road
but also on water, electric drives are being
used increasingly. Their benefits are obvious:
less noise, fewer emissions. Sales figures
are rising accordingly, and the entire production
industry is steadily growing. The industry
is currently in transition.
Many companies, especially from the electronics
sector, are seeing opportunities to enter
the car industry in new areas.
The key players up to now have noticed the
change too.
The challenge for electronics manufacturers
will certainly be the initial high investment
in short production runs, because all the
technologies are very sophisticated and very
complex.
We, as a mechanical engineering company, would
of course be pleased if any additional, specific
requirements came from e-mobility that we
could adapt or integrate into our machines.
Range and power management are the latest buzzwords.
Optimization of power electronics
will increase the efficiency of motors and batteries.
And not just on four wheels.
In contrast to electric drives on roads, the
performance of an electric drive on water
is slightly different. There’s no stop-and-go
traffic on water, for instance; regeneration
during braking doesn’t work in water either;
and also, unfortunately, energy consumption
at faster speeds in particular is far higher
because the resistance of water is greater.
So that’s why we have to place great importance
on the energy densities of batteries, to get
a good range, and also design motors for a
high continuous load.
With electric ship motors, size and weight
often play only a minor role. With cars, things
are different.
The biggest challenge for us is miniaturization
– the contacts are becoming ever smaller,
and so are the pins and the housings. On the
interfaces there used to be 90 pins, and now
we have 150 pins. This makes mounting technology
even more challenging. Monitoring and checking
it is the biggest technological challenge
facing us.
E-mobility has the potential to influence
the entire value chain of electronics manufacturing.
