Team Members: Brian Uznanski uznansk2 Nikhil Kamath nkamath2 Dalton Hite dchite2 Problem Statement: Rapidly charging smartphone batteries leads to unnecessary battery degradation due to increased heat during charge and a greater amount of time spent at 100% SOC. Additionally, existing power packs rarely include rapid charge functionality or charge rate indication. Proposed solution: An AC/DC wall adapter with an intelligent charge rate limit and a built in rapid charging battery. The device will have a button for the user to select a charge rate limit manually and indicators to display charge rate, charge rate limit, and an SOC indicator for the internal battery. Requirements: Intelligent charge limit selection with user override. LED indication of charge rate, charge rate limit, and battery SOC. Internal battery rapid charging. Constraints: Size is a key constraint, as is effective heat dissipation. Uniqueness: To our knowledge, there are not yet fast chargers on the market that support seamless switching between charge rates from a single port. Additionally, no chargers have any kind of learning algorithm implemented to automatically switch between fast and slow charging when the user does not want to make that decision.
