    After a week of intense competition, the 2015 World Solar Challenge successfully ended on October 25 in Adelaide, Australia. Beijing Institute of Technology (BIT)’s self-developed car “Sun Shuttle” accomplished the game after a fifty-seven-hour competition. “Sun Shuttle” was designed by shuttle light solar car team of BIT. As the only participating team from mainland China, shuttle light solar car team verified the solar car system's overall performance. This year, the mileage of pure solar-powered vehicles amounted to 1823 km, 400 km more than that of 2013.
    The World Solar Challenge originates from Australia which covers 3,022 km (1,877.8 miles), and it is held once every two years. The objective of this competition is to promote research on solar-powered cars. After thirty years’ development, the World Solar Challenge has now become the most authoritative and influential car race in the worldwide, which also represents the highest level in the realm of solar car. In the year of 2015, over fifty teams from all over the world participated in the race. Contestants were asked to design a solar car and drive it through the Australian Outback, from Darwin, Northern Territory to Adelaide, South Australia, during which they could only use solar energy to power the car. The race had stringent requirements for efficiency, weight, security and reliability of the car.

    It took shuttle light solar car team of BIT ten months to design the “Sun Shuttle”, during which the designers finished primary design, simulating calculation, body processing, assembly, adjustment procedure of the electric system and vehicle performances test. The team adopted lots of new techniques, such as low wind resistance, efficiently driving motors, optimum structural design and overall vehicle energy management system design. Finally, the car reached a maximum speed of about 65 mph, cruising speed of ninety mph and weights 175 kg. It was driven by single wheel motor with a solar panel of six square meters. Under ideal illumination conditions, top speeds of the solar-powered vehicle could reach 79 mph.

    This competition was a challenge for not only the team members but also the solar car. When confronting problems, team members gained valuable experience and they had to enhance their team work spirit to ensure that they can cope with those problems quickly and accurately.

    Communications with technical officers and other teams benefited BIT students a lot in the aspect of design, driving strategy and team organization.

    The World Solar Challenge is a combination of energy saving, scientific research innovation and personnel training. We believe that the participation will certainly provide valuable experience for the development of China’ s solar car and help China to be among the highest in the world in the field of solar car.
