Year in Review, 2015-16

It has been quite an amazing year for the Shenandoah Valley Governor’s School Electric Vehicle team. Team membership has gone up, a lot of projects have been completed, and there are big plans for the future.

Over the summer of 2015, the team installed the Orion battery management system in the Datsun 240Z. This system was incredibly helpful to the team all year and will continue to be helpful as it provides a way of monitoring all the batteries at once and protecting them from damage during racing. Also over the summer, the team’s website was created and has been a helpful tool for documenting our progress all year.

During the Fall and Winter, the team worked on increasing team membership by recruiting at home schools and presenting to all of the juniors during their physics classes. We got a lot of work done on the Porsche, most of which was cosmetic. The team fixed the switch for the reverse lights and beeper which had broken off, attached covers for the steering column and fuse block, put in a new ignition, and worked on charging lithium ion batteries to be put in the Porsche when the time came to convert it. The team received a storage shed early on and we quickly filled it up and used it for storing all of the things that had previously been kept in the mail truck. As for events, the team participated in the EV Neat Rally at NCCAR from October 9th through the 11th. The team also showed the Porsche in the Waynesboro Christmas Parade. During school, we had meetings with some of the team members during third block independent work time to plan out goals for the near and distant future. On the Datsun, the team added about 36V to the back and put in David Waterman’s pack of batteries from his lawnmower that he donates to us every year. Every Fall, Romanian exchange students come to the Shenandoah Valley Governor’s School; this year, one of our team members brought her exchange student to a meeting to show her our electric vehicle program.

Spring has been an exceptionally busy time for the EV team. We started the new year off with an outreach event with the RAW Learning Private School where team members gave presentations to younger students about the EV Challenge, our cars, and even about the solar panel that the Governor’s School received from Dominion. We began the process of converting the Porsche from lead acid batteries to lithium ion batteries by taking out all of the old batteries, configuring how the new batteries would fit in the Porsche, creating wiring diagrams, and installing racks for the batteries. Members of the team worked with Dish Network on getting a donation for the EV program. A proposal was submitted for funding ideas on many small projects; however, Dish was looking more for one big project to put their money towards rather than many smaller things. The team took the Datsun to the EV Spring Thaw Event at NCCAR in the middle of March. As for work done on the Datsun this Spring, a passenger seat has been put in, 12 cells have been added to the front to bring the car’s overall voltage up to around 176V, and a lot of progress has been made with the battery management system including setting safety features and analyzing data collected from it. The team showed off both the Datsun and the Porsche at the SVGS Open House on March 24 and also participated in the Herald Miller Invitational at NCCAR, an event created to replace the postponed EV Challenge. At the Herald Miller Invitational, the team was interviewed by a crew from an educational website called itsourair.org which will be creating an episode about electric vehicles and the cool things we do at EV to be shown in classrooms all across North Carolina.

An ongoing project with the team is that we are working on installing a touchscreen in the Datsun that we can use to monitor our batteries while we are racing.

Some overall things worth mentioning include that the senior members of the team collectively earned 850 hours. Team membership has increased from 2 members last year to 8 members this year. Also, on the school initiative forms, a system of scoring teams used by the EV Challenge based on categories relating to public relations, the team scored 162 points, significantly higher than what we scored last year.

The team’s plans for the near future as well as next year include taking one of the cars to the SVGS Awards Picnic, getting tires donated for the Porsche, finishing converting the Porsche to lithium ion batteries, continuing to expand team membership, continuing to work with Dominion on getting a grant for an EV charging station, continuing to expand team membership, getting some type of speedometer function for the Datsun, and upgrading the motors/controllers in both of the cars.
