Course Expectations:

This course will be both lecture and hands on based education that will require your participation. There are clear safety issues that will require your complete observance and compliance. Electric Vehicle Systems are a broad emerging topical area and the course will have a team of instructors providing you lectures and direction on the various aspects of the topic area. We will ask that you develop name tags for your desks for lectures. All Faculty involved in this course will have input in the grading and evaluation process. You will have various expectations for weekly homework, Blog entry, papers and group project which require you careful budgeting of time. The group work will require out of class meeting and design work. Each group will need to develop meeting times as needed to achieve the course goals.

SAFETY: This course may involve the use of laboratory and/or shop equipment, and no student is allowed to utilize methods/techniques without the supervision of course instructors. This safety requirement includes all aspects of the development, construction, assembly, transportation and operation of all components of the EV Kart, as well as the EV Kart itself. As a rule, once the EV Kart is capable of self-contained movement (i.e. includes a motor, drive system and power source), the EV Kart may not be powered if anyone is within 15 feet of its direction of movement (i.e. don’t turn it on until there is no one standing in front of the vehicle). This rule is paramount to safety in electric vehicles because, unlike vehicles that are powered by internal combustion engines, there is little or no noise emitted from the vehicle to indicate the vehicle is under power. Furthermore, given the high amount of torque of electric motors at low RPMS, the vehicle can unexpectedly lurch forward with a great amount of power thereby potentially causing great harm. Any student who chooses to disregard ANY safety rules, or conducts himself/herself in a manner that places anyone in danger, will be dismissed from the course immediately, and the case will be turned over to the Dean of Students.

Electric Vehicle Systems - Group Project Paper

One of the desired outcomes of the class is to communicate and demonstrate the importance of team building skills and effective communications with participating on a design team. A significant lesson learned from various case studies of successful and unsuccessful projects is the need to be able to work together and communicate more effectively.

Each member of the class will be assigned to a team that will address a design problem. For the duration of the course, each team is expected to work together and produce a professional quality response to a problem in the form of a written report and a poster/PowerPoint presentation. Final reports are due the day of the presentation which will take place during the last two class periods of the semester. Each member of the team, regardless of input, will receive the same grade for the team project. The projects will be judged by a panel consisting of the course faculty and external experts in vehicle electrification.

I. Executive Summary.

II. Table of Contents, List of Team members, and Specific Team Member Contribution.

III. Problem Statement, Design Objectives and Development of Requirement.

IV. Methods and Discussion Leading to Proposed Design.

V. Schedule.

VI. Results Including the Measures of Success (speed, range, conservation of energy).

VII. Equipment List for Go-Cart Design.

VIII. Lesson Learned.

IX. Power Point Presentation Slides.

X. References (Bibliography)

All teams should plan for a team project – In Process Review. After students are assigned to team building groups with a designated project, students will have approximately 3 weeks to make progress on the assigned problem. At this time, all team members will meet with their faculty advisor and discuss progress made and future plans. A written progress report will be turned in and an oral report will be given to the faculty advisor. There will be no scheduled lecture to facilitate the In Process Review meetings, but students are allowed to meet at another time approved by the faculty advisor. Other individual assignments may be requested by faculty advisor as it pertains to the team building project.

Final Paper requirements include:

• Typed, 11-point font, single-spaced.

• While length will vary, we expect approximately fifteen to twenty pages not including appendices.

• Minimum of eight to ten references (i.e., appropriate, scholarly, credible).

• Formatting and style used for content, references, and citations should be specified; default acceptable systems include:

o APA ( owl.english.purdue.edu/owl/resource/560/01/ )

o MLA ( owl.english.purdue.edu/owl/resource/557/01/ )

o Chicago ( )

• Ready for submission and possible publication in a scholarly journal or Purdue EV Website.

• The final submitted copy should be bound in a professional manner (either in a binder, with comb/spiral binding with “nice” covers front-and-back, or another professional-looking binding) and submitted both in hardcopy and electronically; the presentation file should also be submitted electronically

Weekly Homework and Group Activity Journal

Individual Homework:

Students will be required to prepare questions with answers, a website of interest relating to the weeks topics, and exact references for both. Two short answer or multiple choice questions and One website with minimum 2 paragraph-maximum 1 page summary are due every Wednesday before class (one question shall be prepared for each class period based on the assigned readings or the lecture for that class period).

Preferred submission: electronic submission prior to class

Unacceptable submissions: Handwritten submissions

• Items must be original; those that are not original (e.g., those already appearing in an assigned reading, already submitted in a previous semester) will be treated as plagiarized

• Answers must be provided with questions

• Website link and a 3-5 line summary should be included with submission

Citations for questions and website must be included for verification; expected citation format is MLA, APA, or other professional citation style, together with page number or equivalent identifier.

Group Activity Journal:

Based on the group project lecture from the first class period, each student team will prepare a group activity journal with the weekly progress towards developing the electric vehicle design and race ready go-cart. The journal will include references, pictures and engineering calculations. The purpose of this journal is to allow future go-cart project teams to use your group project as a guide and advice for improving the design process. We will provide a web site for the journal.

Each project team will also establish a “Facebook” fan group for the project team. The teams will compete with other course teams for the most fans that their sites have acquired over the period of the course. The final fan number will be submitted during the student project reports.

Summary of Other Requirements

1. Class attendance is mandatory and will be recorded for each class

2. Students should be prepared to discuss all required readings before each scheduled class

3. In-class contributions to discussions are part of the course evaluation; students are expected to participate and contribute to discussions for the good of the whole class

4. Student generated sample test items are due every Wednesday (unless otherwise specified by the Faculty) that relate to lectures and reading materials from the previous week (i.e. previous 2 class periods)
