Kicking Off the Year, 2016-2017

The Electric Vehicle team started the year early, with the first meeting of the new school year on Sunday, August 14. We’re proud to welcome new members Ryan Marx, Nolan Vess, Ethan Choate, Eric McKenzie, Parker Turnage, and Josh Bryant.  Since the first meeting of the year we’ve installed a new auxiliary battery pack in the Datsun, done body work such as fixing the side view mirrors, worked on reparing the Datsun’s bumper, and ambitious new members have even fixed the outside door handles. A cataloguing system for all the team’s batteries has also been constructed, with cloud updating capabilities. DSC_0386.JPG

The EV team put on a good showing at the SVGS STEM open house, showing new SVGS parents and students both the Porsche and Datsun. We were happy to tell new students all about the benefits and experience gained being part of the EV team.

An exciting new addition to the Datsun is the Raspberry Pi tablet PC installed in the Datsun’s dashboard, which will allow for easier and on the go data collection from the Orion BMS system. The Pi was installed at the end of last year by team member Ben Lawn as his senior project, however our first field run with the Pi will be at our first event at the end of September.

With our very first event of the year being on September 30th down at the North Carolina Automotive Research Institute, the team is working quickly in order to prepare the Datsun for some racing! David Waterman has generously donated his electric lawnmower to the EV Team, which we’ve extracted the BMS from and placed in the Datsun. Weighing in at about 200 lbs, the team had to do a little engineering in order to safely transport the BMS pack into the Datsun correctly, utilizing some metal pipes and rope. The team aims to wire the BMS into the Datsun and construct a 172 volt battery grid in time for our first event.

Here’s to a successful and fun year for the Shenandoah Valley Electric Vehicle Team!

This Week in EV 9/27 – 10/3

On Sunday and Wednesday, the team met from 6 to 9. We rethought the Datsun battery wiring to allow for easier connection of additional cells to the BMS and drew a diagram to reflect these revisions. We made new 1 gauge wiring to fit into the new wiring scheme. We continued charging cells and installing charged cells into the car.

This Week in EV 9/13 – 9/19

On Sunday the team met from 6-8:30. We began the meeting by looking at a hybrid electric vehicle owned by a member of the community named Katie. We then showed her our cars and discussed a wide range of electric vehicle topics with her. A new member, Nathaniel, showed up and was able to see the cars and get a safety walk through from Byron. We continued charging batteries and preparing for the Porsche conversion. David Waterman, one of our teams sponsors, will be bringing back his lithium ion pack that we borrow from his lawn mower (the fastest zero-turn Dixie Chopper in the US) to be put in our Datsun again. With all immediate work done on the Porsche, the team turned to the Datsun. The Datsun’s wiring was the main focus of last year’s team; all the wiring was taken out and completely redone partly as a learning opportunity and partly out of necessity. The team checked to ensure all auxiliary factors were working properly and charged up the auxiliary battery. After that, the team discussed the possibility of going out to a local business later in the week to try to get tire donations for the Porsche.

On Wednesday, the team met from 6-7:30. We wired a switch to turn on and off the auxiliary battery to prevent it from discharging on its own.

This Week in EV 9/6 – 9/12

On Sunday the EV team met from 6-9. We got a donation of a shelving unit from one of the team member’s parents for use in our new shed. The first part of the meeting was spent assembling the shelves and getting them in place in the shed. They were immediately put to good use. The team continued working on charging batteries and making progress on the Porsche 911. The new ignition is in place and functioning, we discovered where the switch was for the reverse lights and beeper (it had broken off) and have plans to fix it, and the covers for the steering column and fuse block were put in place. Another thing that got accomplished at the meeting was that the mail truck, which has previously been used for storage, has been cleaned out and organized.

On Wednesday, the team met and replaced the switch for the reverse lights and beeper, sorted through some documentation on the Porsche, and continued charging batteries.

This Week In EV 8/30 – 9/5

On Sunday, the EV team met from 6-8 to work on clearing out our new storage shed and developing a list of goals for the NEAT Rally in October. Our goals include getting the Porsche converted from lead acid batteries to lithium ion batteries, getting our batteries back in the Datsun in a new configuration, and setting up our BMS to match the new configuration.

On Wednesday, the team met from 6-9 and welcomed a new member, Caitlin, to the team. We gave her lessons on safety and then got to work on the Porshe 911. We put it up on the lift to look for a solution to a problem with the reverse lights and wiring. We also began charging batteries that were donated last year so that they could be put in the Porsche as part of its conversion from lead acid batteries to lithium ion.
