Project Page

The Project Pages were created in an effort to help promote student projects. The Project Pages provide a showcase where employers, other students, and friends can see what UIUC students are capable of. Many employers, in particular, consider a good Senior Design Project to be just as valuable as internship experience. The Project Pages will develop over time into a valuable library of practical engineering knowledge. Some of the best projects will be identified each semester and placed in the Senior Design "Hall of Fame," while the rest will be accessible by semester and search engine.

Updating Project Information

Once your project has been approved on the discussion board by the Instructor, you should promptly update your project information. In order to do so, find your project on the Project page, and click its title. When a frame expands, click on "Edit." Next, enter your UIUC netid and password. The system will lookup your project and prompt you for information such as your project's title. Please fill in the information that you wish to have appear for your project, and then click on the submit button. The required fields are marked so. You can update this information at any time. We strongly urge you to keep a backup of all of the information, and we would like to caution you of one scenario in particular. If multiple people attempt to edit this information at the same time, the second person to submit the changes will overwrite the first person's changes. Also, be sure to logout when you are done by closing the web browser. It is important that you provide a project desciption. It should be a brief overview of your project and explanation of why it is worth doing. Please provide this information as soon as possible and try to limit the length to about 250 words.

Submit Schedule

After updating your project information, you should proceed to the Submit Schedule page. Here each student should submit his/her schedule so that your TA can schedule a weekly meeting time. We know that there are a lot of boxes to check, but we need this detailed information because of how difficult it is to match schedules. The information is displayed in a convenient way for TAs when it is time for them to schedule meeting times. The system is very intuitive so instructions are not needed. NOTE: Please be sure that the schedule you submit is as accurate as possible, since you won't be able to edit it later!

After submitting your schedule, you should familiarize yourself with the "Upload Files" page.

Uploading Files

This area is used to upload files such as the Proposal, the Final Paper, Images, and additional files. When a file is uploaded, it is renamed and limited to a specified size. Special documents such as Proposals and Final Papers should be uploaded into the appropriate slot and will automatically be added to your Project Page. Images and other files can be uploaded into any other slot such as "file1." To upload a file, simply select which slot to place it in, and then select the file from your computer using the "Browse" button.

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.
