Design Of Novel Charge Balancing Networks In Battery Packs, D. Dane Quinn, Tom Hartley
Dr. D Dane Quinn
In a modern battery pack, the charge in the individual cells can diverge in time, leading to decreased capacity and reduced operating life of the pack. Charge balancing systems can be introduced to equalize the state of charge across the multiple cells, therefore increasing the performance of the battery pack. This work considers the dynamic performance of charge balancing systems, and through simulation explores how their ability to equalize the state of charge depends on the design of the underlying charge balancing network. The performance of the charge balancing system is described in terms of the rate at which the …

Oxygen ionic transport in conducting ceramics is an important mechanism enabling solid oxide fuel cell (SOFC) technology. The multi-physicochemical processes lead to the fact that the distribution of oxygen vacancy site fraction is not uniform in a positive-electrode electrolyte negative-electrode (PEN) assembly. Different oxygen vacancy concentrations induce different volumetric expansion of ceramics, resulting in complicated chemical–mechanical coupling phenomena and chemical stress in SOFCs. In this research, a mathematical model is developed to study oxygen ionic transport induced chemical stress in an SOFC. The model is validated using experimental polarization curves. Comprehensive simulations are performed to investigate chemical stress distribution in …

The goal of the Gaze Controlled Human Computer Interface project is to design and construct a non-invasive gaze-tracking system that will determine where a user is looking on a computer screen in real time. To accomplish this, a fixed illumination source consisting of Infrared (IR) Light Emitting Diodes (LEDs) is used to produce corneal reflections on the user’s eyes. These reflections are captured with a video camera and compared to the relative location of the user’s pupils. From this comparison, a correlation matrix can be created and the approximate location of the screen that the user is looking at can …
