Greg Room GJ101 Tools

Wikipage - Chihan

Reschedule full team meeting.

Block model of batteries and Test Setup

Agenda 10/22/13 • Update on test setup • Results thus far • Update from structures team • Chihan to update on wiki page

Minutes of meeting on October 22, 2013, 12:30 PM[edit]

Update on test setup: BMS arrived and pin out connections were terminated. BMS connected to computer, firmware update, and BMS works great! Can view data. Going to read into everything about the BMS.

Results thus far: Still doing initial testing, but am pretty happy the battery management system worked on first try! Greg is going to build us cables.

Update from structures: Have them working on a heat transfer model. They're making a basic transfer model to test and see how it works then we are going to give them our parameters. Also meeting with them on Thursday at 3:30pm to discuss containment vessel options.

Chihan - Wiki page

Quick Meeting with Gillette Zenner: • Single cell voltage min-max • Time to discharge from full range • Ohmic power generation from + to - terminals • Power=VI=V^2/R=i^2*R • Temperature range from charge to discharge

Final Deliverables • Final report • Website • Logbook • Poster • Presentation (between return from thanksgiving and dead week)

Agenda Next week • Update on battery testing • Conclusive results from battery testing • Update from structures • Single cell model • Containment vessel • Chihan Wikipage update

Meeting notes for November 3, 2013 Met in BEL 102C and discussed our test setup.

Meeting notes for November 4, 2013 Completed single cell #2 test with nichrome bank

This test was conducted over 8 minutes at 20 second intervals. The entire was conducted with a single battery breaker, nichrome bank, and current sensor. Rnichrome = .088ohms. Rnichrome was calculated from the voltage vs. current measurements.

Our results represent a typical battery discharge curve so that is good!!!

Meeting notes for November 5, 2013[edit]

No one showed up at meeting, so meeting was moved to the lab.


Minutes of meeting on November 12, 2013, 12:30 PM[edit]

Met with entire team in the formula hybrid shop to determine the approximate space that we have for our overall full scale battery system. Also talked with Jaz about having her help us on the single cell Simulink model considering this task wasn't brought up till October 8th, and none of the EEs on the team have ever used Simulink before.

Minutes of my life I wish I could have back for November 14, 2013

Met with battery and structures team to try and create a Simulink model of batteries with Jaz, but Simulink had errors and nothing was accomplished.

Goals to finish semester: 1. Design report • Need to update context/text • Already have overall structure • Update title page/template 2. Design poster • Update content 3. Finished product 4. Snapshot (Mini Expo) • Poster • Finished product • Demonstration of finished product 5. Logbooks 6. Wikipage ( • Pictures • Battery test plots
