Final Presentation

Description

Presentations of the projects are given a few days after the Final Demo to an audience of fellow student reviewers, the lab instructors, and occasionally faculty or even students from outside the class who are following up a project of personal interest to them. The style is formal and professional, and students should dress accordingly.

Requirements and Grading

Each project team has 25 minutes for a Powerpoint presentation and questions. Every group member must present their own work contributing to the project and be ready to answer questions. Individual grades are given, and everyone in the audience participates in evaluating the presentation. Talks are judged on the basis of presentation technique and of technical organization and content.

Points of technique include dress, use of display materials and their design for readability, clarity of speech, absence of annoying mannerisms, proper eye contact with audience and smooth transitions between speakers. Content is judged on use of a proper introduction, orderly and connected development of ideas, absence of unnecessary details, proper pacing to stay within the allotted time, and an adequate summary at the close of the talk. Quantitative results are expected whenever applicable. Here is a general outline to follow:

  1. Introduction
  2. Objective
  3. Review of original design, requirements, and verifications
  4. Description of project build and functional tests
  5. Discussion of successes and challenges, as well as explanations of any failed verifications demonstrating and understanding of the engineering reason behind the failure
  6. Details of other tests including tests not explicitly required for verification procedures
  7. Recommendations for further work

Any significant relevant ethical issues should be briefly addressed, preferably in a single slide.

Presentations will be graded using the presentation grading rubric. Two sample Presentation documents - with notes at the top - are available at: Sample PRES 1, Sample PRES 2

Here are some recent presentations you can refer to: FA20_Team13, FA20_Team3

Submission and Deadlines

Slides for your final presentation must be uploaded to your project page on PACE prior to your presentation time. Deadlines for signing up may be found on the Calendar. Sign-up for the final presentation is done through PACE. Remember to sign up for a peer review of another group.

The goal of this project is to design a low cost BMS (Battery Management System) system that is flexible and modular. The BMS must ensure safe operation of lithium ion batteries by protecting the batteries from: Over temperature, overcharge, overdischarge, and overcurrent all at the cell level. Additionally, the should provide cell balancing to maintain overall pack capacity. Last a BMS should be track SOC(state of charge) and SOH (state of health) of the overall pack.

To meet these goals, we plan to integrate a MCU into each module that will handle measurements and report to the module below it. This allows for reconfiguration of battery’s, module replacements. Currently major companies that offer stackable BMSs don’t offer single cell modularity, require software adjustments and require sense wires to be ran back to the centralized IC. Our proposed solution will be able to remain in the same price range as other centralized solutions by utilizing mass produced general purpose microcontrollers and opto-isolators. This project carries a mix of hardware and software challenges. The software side will consist of communication protocol design, interrupt/sleep cycles, and power management. Hardware will consist of communication level shifting, MCU selection, battery voltage and current monitoring circuits, DC/DC converter all with low power draws and cost.
