g3090It’s time to get back to work again: another exciting school year has started. This year NU solar is focusing on preparing SC6 for FSGP 2015 where we hope to be highly competitive. We are also begining the design process for our next car SC7! This next generation solar vehicle will be a four-wheeled car with a steel frame and designed for durability and reliability. We’re very excited about this new venture, and we hope that you will join us.

If you are interested in solar power technology, alternative energy, or you just like working on cars in general, please join us. The first team welcome meeting will be held:

Sunday, Sep. 28th, @ 12:00 pm in Ford Design Center.

(Date is subject to change; we have an outreach event on Saturday)

We have many teams, and we need new members for all of them:

  • Mechanical
  • Electrical / Software
  • Sponsorship and grant writing
  • Publicity, Communications and Web Administration
  • Public Outreach

Head over to the Join Us page or e-mail projectmanager@nusolar.org for more information.

Sunday Excursion in SC6

Posted on by Alexander Martin Posted in General Info, Race Preparation | Leave a comment

ALX_0002-001As the final weeks of the school year wrap up, we have finlly begun to seriously test SC6. On Saturday, following our weekly work session we took the car out on the first on-road excursion that it has been on in three years–top shell and all. The car performed very nicely, and there were no gliches in either the electrical or mechanical systems. On Sunday, then, we planned a slightly further excursion north eighteen miles to Lake Forest, IL, and back.

We drove past the Bahai Temple and then up along Sheridan Rd. with a lead and chase car clearing the way. On the road, SC6 got plenty of wowed looks from passerby. The nice weather and long weekend meant that there were lots of bikers and pedestrians outside who saw our vehicle. We had the chance to interact with an interested family during one of our pit stops. The young boys thought that it was cool that our car didn’t use gas.

Once again the car performed very nicely, even on some of the most pothole-laden streets. We successfully made it up to Lake Forest in 2 hours, making only two preventative stops to make sure the car’s systems were all working. Round trip, we put about 36 miles on the car. We plan to do many more excusions and to improve on this figure before the school year is out.

 

Back on the Road

NUSolar is back on the road (almost)!

After a long and cold winter quarter, the sunshine is greatly appreciated by both SC6 and the rest of the team. Over the past four weeks we have had the car out and about under its own power several times. Work on the array stand and canopy are still not finished, but we have installed a new touch-screen control for the driver as well as new, long-lasting batteries for the car’s auxiliary systems.

Heavy lead-acid batteries served as replacements for our old Lithium-ion cells during testing, but will not be permanent.

The car’s software is continually being updated by the telemetry team. We recently installed a new steering wheel-mounted touch-screen to host the driver controls. In addition to horn and drive/reverse switches, this system will also give drivers live feedback of battery levels and other vital signs of the car. As always, the process of incorporating this new system is fraught with bugs, but we’ve been able to sort them out quickly and get things running.

In mid-April, we took the bottom half of the car out for a test-drive around Northwestern’s campus. Starting from Ford we headed down via sidewalk to Norris, where we topped up the tire pressure. The car performed very well accelerating both the inclines and planes. We also got plenty of interested looks from passerby’s.

Before we can take the car out on the road, we still need to get a license plate. Nevertheless, we’re really excited about the way things are shaping up, and we look forward to a great summer.

Preparing to test the car

Suspension Components

We recently received the suspension components we redesigned. HyTech Spring and Manufacturing in Plainwell, MI machined them for us.

Here’s an overall view of the front mount plates.

The plates now have curves on the tabs to distribute stress that we had difficulties machining in-house previously.

GM Foundation donation

We’d like to thank the General Motors Foundation for their recent support of our team!

GM

Here’s an overview of the GM Foundation’s charitable activities, as shown on their website:

“Since its inception in 1976, the General Motors Foundation is dedicated to giving back to communities across the country. Over the past decade, the Foundation has donated more than $315 million in grants to support nonprofit organizations within the areas of Education, Health and Human Services, Environment and Energy and Community Development.

Today, the Foundation focuses on investments in education that support the next generation of leaders and innovators, particularly in the fields of science, technology, engineering, and math (STEM). Beyond supporting the education of our nation’s youth from pre-school to college through initiatives like the Buick Achievers Scholarship Program, the Foundation gives students hands-on experiences that further their environmental studies and cultural experiences within their communities. In addition, the Foundation has a 15-year partnership with Safe Kids Worldwide to provide programs that lead to safe habits both inside and outside of cars.”
