The AERO Team at Beihang University: The Movement Towards the Unmanned Electric Vehicle

By Chroma Electronics

During the 8th anniversary of the Formula Student China (FSC) organization, Beihang University’s AERO team celebrated a decisive victory using their premiered retrofitted electric car at the first annual Formula Student Autonomous China (FSAC) competition. In recent years, the direction of electric vehicles has been trending towards a new technological state of autonomy, or “self-driving.” Beihang University is one of the few top universities in the FSAC to participate in, not only both traditional fossil-fuel and electric vehicle competitions, but now also the “unmanned” vehicle movement. Thus, the team required a higher level of technology to back up its demands; the hardware and software needed to be functionally integrated with high complexity to ensure stable operation of electronic product. Chroma Electronics provided the university’s AERO team with professional testing equipment and experiences to assist in achieving its electronic vehicle development plans and to improve the overall unmanned vehicle campaign.

The development of electric vehicles is one of China’s most important growth strategies, driving both the battery and energy storage industries.
Chroma’s automatic test systems (ATS) offer a wide range of AC/DC power supplies, electronic loads, and electrical safety tools to test EV/HEV related parts and equipment. Chroma’s multifunctional ATS can also be applied to power electronic devices like EVSEs, car chargers, DC/DC converters, motor drivers, etc. In addition, the system validates the high-voltage parts, checking the charging circuit and the potential equalization of the automotive body for electric cars. A powerful software testing tool is provided to help integrate the DC power supplies and electronic loads in order to perform necessary tests on the battery storage system.

Furthermore, the Formula SAE Electric Racecar competition, hosted by SAE International, nurtures future talents in China’s new energy automotive industry. Chroma Electronics has been a part of China’s new energy industry for years while supporting the social responsibility of shouldering numerous formula student electric team endeavors. Chroma’s multiple test solutions have received recognition from China’s energy industry and academia as well by helping customers identify the potential risks during the design verification process. Chroma’s solutions correct these product problems in order to accelerate the R&D process and to propel new business opportunities.

Chroma Test Equipment Designated by IFEC 2017 for Power Supply Competition

<Note: This article was released on September 6>
The IFEC, initiated by IEEE, is an international student competition for innovation, conservation, and effective use of electrical energy, which is open to college and university student teams from recognized engineering programs in any location.

Chroma, the world’s leading manufacturer of test instrumentation, has been the only official designated equipment sponsor for three consecutive years and recently participated in the competition held at the Virginia Polytechnic Institute in the United States. A Chroma 8000 Automated Test System (ATS) was customized to perform the test items for the competition where students were to create high efficiency, high density isolated DC-DC converters. The data measured by the Chroma 8000 ATS was used as the evaluation criteria and the test items are summarized as below:

Test Items Measurements
Steady State Test Output boltage, ripple voltage, efficiency
Load Transient Response Test Output voltage waveform, positive/negative overshoot voltage
Burn-in Test Output voltage, ripple voltage, efficiency

To cope with the competition requirements for high accuracy and high current slew, the 8000 ATS was equipped Chroma’s 63600 Series high precision electronic load with a sampling rate of up to 500k Hz and a 2A/µs current slew rate. Combined with the open software architecture of the Chroma 8000 ATS, a complete test report was generated to give the judges an important reference to rate the competition entries.
