STMicroelectronics: Two Cars Leveraging STMicroelectronics Technology Set to
Race in World Solar Challenge
Stanford Solar Car "Luminos" and Onda Solare "Emilia 3" use ST technology to
power their vehicles across the Australian Outback
Geneva, October 2, 2013 - The World Solar Challenge is set to kick-off on
Sunday, and this year two cars are being powered by technology from
STMicroelectronics (NYSE: STM), a global semiconductor leader serving
customers across the spectrum of electronics applications.
The Stanford Solar Car Project, a non-profit group comprised entirely of
students at Stanford University, selected the STM32 F4 series of
microcontrollers for use on the 2013 Luminos solar car. The solar car uses
dozens of ST microcontrollers to monitor battery life and solar-panel
efficiency and to control the electric motor and driver-control functions -
key factors to completing the race across the harsh Australian Outback.
Ultimately, the STM32 microcontroller enabled the students to optimize the
performance of their car based on real-time analysis of vehicle and
environmental conditions. And since the ST microcontrollers are in constant
communication with each other, all the data can be processed and logged on the
car in real time and transmitted to the rest of the team in a chase vehicle
during the race to ensure the solar car is running smoothly or troubleshoot as
Italian-based team Onda Solare, comprised of technicians, students and
professionals working in the alternative mobility and clean-energy fields, are
also using STMicroelectronics' components in their 2013 solar-car entry. Their
solar car - the Emilia 3 - utilizes ST's SPV1020 interleaved DC-DC boost
converter with an embedded Maximum Power Point Tracking (MPPT) algorithm that
maximizes the power generated by photovoltaic panels on the car, independent
of temperature and the amount of solar radiation captured as the car changes
directions with respect to the sun. The Emilia 3 also uses the SPV1001 cool
bypass switch to reduce power loss and improve efficiency of the energy coming
from the solar panels.
"Both the Stanford Solar Car Project and Onda Solare have chosen different
STMicroelectronics' parts for their solar-car designs, which demonstrates the
diversity of our product portfolio," said George Vlantis, R&D Engineering
Manager at STMicroelectronics. "Both teams have already demonstrated the
reliability of ST components and the expertise of the teams' engineers in the
last race in 2011. We wish both teams the best of luck this year as they set
off on another 3,000-kilometer drive across the Australian Outback."
ST is a global leader in the semiconductor market serving customers across the
spectrum of sense and power and automotive products and embedded processing
solutions. From energy management and savings to trust and data security, from
healthcare and wellness to smart consumer devices, in the home, car and
office, at work and at play, ST is found everywhere microelectronics make a
positive and innovative contribution to people's life. By getting more from
technology to get more from life, ST stands for life.augmented.
In 2012, the Company's net revenues were $8.49 billion. Further information on
