Problem Statement:
There have been recent reports of multi-million dollar companies having to recall entire projects due to their BMS’s malfunctioning or operating incorrectly. The purpose of this project is to analyze the future of batteries, the Lithium-Ion cell, and to exercise a BMS to better understand its capabilities and possible cases for errors. Lithium ion batteries are intolerant of overcharge and overdischarge. Abuse of this kind can result in high temperatures, venting of gases, fire, or explosion. Therefore battery management systems have been devised to prevent such abuse. Recent events such as fires on the Boeing Dreamliner and the …

Bluelock: A Secure Bluetooth Operated Padlock, Trever Mckee
Computer Engineering
For this project a secure, battery operated, Bluetooth operated padlock was created. The project included both the hardware to integrate with a padlock and an Android application used to interface with the hardware. In order to make the padlock secure both AES encryption and challenge response authentication were used for secure message passing between the device and the Android phone. The project also included power consumption and sustainability tuning including exploring Arduino sleep states and integrating the project with a solar charging unit.
