TECHNOLOGY REPORT
Bosch intends to spend a further €250 million in expanding
the clean-room facility at Dresden.
GaN research
Power electronics are key to the needs of electromobility and
Bosch already has been able to extend the range of electric
vehicles by 6% through using silicon-carbide (SiC) chips, the
company claims. Bosch expects the market for these chips to
grow by an average of 30% annually throughout this decade.
This has triggered a hunt for chips that offer greater efficiency
and reduced cost.
For this, Bosch has begun research into gallium nitride
(GaN)-based chips, which already are used in smartphone and
laptop chargers. The higher voltages needed for EV charging,
up to 1,200 volts, mean that more research is necessary before
GaN chips would be production-ready for these applications.
According to Dr Stefan Hartung, chairman of the board of
management of Robert Bosch GmbH, " All in all, chips' share
of a car's total value will quadruple over the course of the
decade - from just under €200 to more than €800. "
Bosch recently demonstrated some of its semiconductor applications
to a small group of reporters, including SAE Media, at
Dresden. Products included a redesigned EV charging cable.
European models normally are supplied with two separate cables,

Bosch chairman of
the board Dr. Stefan
Hartung expects
semiconductor share
of a new vehicle's
value to quadruple
this decade.
