The Herald Miller Invitational

The Herald Miller Invitational, a new event created by multiple team mentors to replace the postponed EV Challenge so that the teams had a year-end event to showcase all their hard work, took place April 14-15 at NCCAR. The SVGS EV team met early Thursday morning to load up the car and head down to North Carolina. We arrived with the Datsun around 8:45 and began unloading the car and talking to other team members about their cars and STEM cycles.

A morning meeting took place around 10 to plan out the activities that would take place at the event, taking into consideration what each team wanted to do. After the morning meeting, we broke into groups that mixed members of different teams together to do student-lead inspections of the vehicles. These inspections involved examining the safety, creativity, and ingenuity of the cars to give teams scores out of 200. The Datsun received an impressive score of 192/200.

The SVGS team then set up an autocross course and timing equipment for all of the teams to use. All members of our team drove the Datsun impressively well, getting the best times of the day on the course. Ben got the top two times, Eric got the 3rd and 4th best times, and Emily got the 5th best time. At the end of the day, we set up our car to charge overnight so that we would be ready to continue racing on Friday.

Throughout the day, a reporter from a local newspaper called The Daily Herald interviewed teams and gathered information about the event. To read the article, see our post announcing the mentioning here: https://svgsev.wordpress.com/2016/04/16/the-ev-team-was-mentioned-in-the-daily-herald/.

On Friday morning, Eric, Ben, and Byron headed to the main research building to participate in a troubleshooting event while Emily stayed with the car to monitor charging. The troubleshooting event was a class and practice session for teams to use troubleshooting boards to find and isolate problems within circuits.

After the troubleshooting class, all of the teams headed down to the track to participate in an altered autocross course from Thursday. The Datsun performed well again but the best times were earned by West Wilkes High School’s Miata, an incredible car that performed really well.

To read about Topsail’s team, a great team that brought two cars and a STEM cycle to the event, go to their website [http://www.kickngas.org/].

Throughout the day on Friday, a crew from itsourair.org followed the teams around to learn more about the program, do filmed interviews with members of the team, and get shots of the cars in action. itsourair.org works to put together educational videos and curriculum to be used for education in classrooms all over North Carolina. When the footage is put on their website, we will put up an announcement with a link to their footage from the event.

The team made it home late Friday night and unloaded the car. Overall, the Herald Miller Invitational was a great event and each member of the team had an incredible time. We can’t wait to get together with all of the teams that attended again in the Fall at the EV Challenge.

This Month in EV, February 2016

Looking back on the goals the team set in January (finish charging the Datsun, participate in more outreach opportunities, get tires donated, get another pair of racing seats donated, and finish converting the Porsche from lead acid to lithium ion batteries), February has been a very productive and successful month. The team has started and accomplished quite a few of the set goals and we have plans for the ones that we haven’t gotten around to yet.

The Datsun is charged up to the best of our abilities and ready to race in the Spring Thaw competition at NCCAR in March. Also, a passenger seat is in the process of being installed in the Datsun (hopefully in time for the competition). Once the seat is in place, we hope to have an outreach event that will allow people to ride in our electric car and get to learn a little bit more about EV. The Porsche is well on its way to being on lithium ion batteries. After a little bit of brainstorming, a layout has been configured for the newer, smaller batteries as well as a wiring diagram. All that’s left is putting the batteries into the newly made racks, wiring them up, and getting the controller put back in place. That being said, it does not look like the Porsche will be ready in time to participate in the Spring Thaw event. Rather, the new and improved Porsche will be unveiled at the EV Challenge in April.

Throughout the course of this month, a team member and an instructor have been in contact with Dish Network and have worked out a grant for the team. This money will be going towards the costs of competitions and will help the team out a lot. Thanks Dish Network!

Next month, the team will be traveling to North Carolina to participate in the Spring Thaw Event. Goals for March include: finish the Porsche conversion, give rides in the Datsun, get one more seat for the Porsche, and get new tires donated for the Porsche. Also in March, the Shenandoah Valley Governor’s School will be having it’s annual STEM Open House and the team will have the cars on display with students to talk about the program and bring awareness to the community.

This Month in EV, January 2016

January has been a pretty busy month for the EV team. Early on, planning was under way through a long series of emails for an outreach opportunity to share what the SVGS EV team is and what we do with some members of the community. That event ended up being a big success. On January 20th, some students from Staunton’s RAW Learning Private School visited the Governor’s School to run through some stations and activities led by members of the EV team. Mr. Daw gave a presentation on what the EV Challenge is and what the competition is like along with a description of the STEM Cycle program. Byron and Ben showed off both the Datsun and the Porsche, allowing the kids to see the cars up close and hear more about how they work and what we do as a team at meetings. Emily led an introductory level class to solar energy that included a brief video, a look at the solar panel that SVGS recently got, and some interactive games focusing on renewable energy.

In addition to focusing on outreach, the team has been putting a lot of effort towards working out charging the Datsun. We’ve hit some bumps along the way with some straggling cells and some cells that seem to be reaching much higher voltages that others. Our original hopes were that the BMS would prevent this but we are finding ourselves having to go in an charge some cells individually. Another thing in the works for the Datsun is the fabrication of a controller fan cover to keep small objects from falling in and jamming the fan while the car is being worked on.

The team has also been working towards accomplishing the goal of getting new tires donated for the Porsche 911 so that we can race it safely at the upcoming EV Challenge. We have taken the lead acid batteries out of the car and are working on planning the layout of the lithium ion batteries.

Some goals for the team in the rest of January and through February include: finish charging the Datsun, participate in more outreach opportunities, get the Porsche tires donated, get another pair of racing seats donated so that people can ride in the cars, and finish converting the Porsche from lead acid to lithium ion batteries. We’ve got a lot ahead of us but the progress we’ve made so far this year has the team excited for what’s to come.

 

This Week in EV 10/4 – 10/10

The meeting on Sunday was rescheduled to Monday due to possible inclement weather. On Monday, the team met from 6-9. While charging the Porsche, the teachers passed out permission forms and legal waivers to the members going on the trip and went over what to pack, the schedule, and general expectations. We replaced the low auxiliary cell with a fully charged one and decided on what hardware we would use to mount the BMS in the Datsun. On Wednesday, the team met from 6-9 and broke into three groups to work on various tasks. One group worked on fixing the connections on the batteries to ensure that the wires would be under any stress when the batteries were held down for racing, the second team worked on charging batteries, and the third team worked on getting timing equipment to work for the races at the competition. Friend of the team, Mark Bartosik, joined us for most of the evening to see that everything was running smoothly and if we needed any help. The team added an extra meeting on Thursday to load the vehicle, supplies, and tools needed for the competition.┬áThe team decided to only bring the Porsche because of the high number of students with prior commitments and because the Datsun was not entirely ready to race. On Friday, the team met at 4:30 am and headed to North Carolina for the EV Neat Rally. Click here to read more about the competition at it’s dedicated post.

On April 24-26, the SVGS Electric Vehicle team went down to North Carolina to participate in the 2015 EV Challenge at NCCAR (North Carolina Center for Automotive Research). The team competed in events such as autocross, acceleration, range, vehicle design, oral presentation, EV jeopardy, and troubleshooting; the team received recognition in many of these categories. Each team member got a chance to work on their driving skills on the track and expand their knowledge of electric vehicles by talking to members and mentors of other teams at the competition.

The team showed two cars this year: the Datsun 240Z and the Porsche 911. The 240Z performed on ~150V of Lithium Ion batteries while the Porsche ran on Lead Acid batteries. Future plans for the cars include the installation of new battery management systems on both and the conversion of the Porsche to Lithium Ion batteries.
