A Data-Driven Lithium-Ion Concentration Estimator for Electrode Solid Phase in Battery Models.
Cai, Le (2023-08-09) ETD File Embargoed
This thesis introduces a data-driven approach for lithium-ion concentration estimation in
battery cells, leveraging a deep learning model based on Long Short-Term Memory (LSTM)
networks. As lithium-ion batteries gain ...
Development of a Multi-mode Adaptive Controller and Investigation of Gain Variations with Speed and Balance Changes
Jantz, James (2014-03-20)
Magnetic bearings offer a number of advantages over conventional rolling element bearings. Magnetic bearings provide support for rotating systems through magnetic levitation rather than by mechanical contact, nearly ...

Development of a reduced order electrochemical and thermal model for Lithium battery with blended cathode
Li, Xueyan (2014-12-12)
Accurate and fast estimation of state of charge (SOC) and state of health (SOH) during operations plays a pivotal role in prevention of overcharge or undercharge and accurately monitoring the state of cell degradation, ...
The Effect of State of Charge and Charge Rate on the Formation and growth Deposit Layer on the Anode Electrode of the Lithium Ion Battery
Agubra, Victor (2014-12-09)
The lithium ion battery technology has for the past two decades received a lot of attention because of its high energy density and excellent cycle life compared to other battery chemistries such as lead acid and Ni-Cd. ...
A highly efficient reduced order model considering aging effects for lithium ion polymer batteries
Zhao, Yinyin (2017-01-04)
Mechanisms for ion transport, diffusion, and intercalation/de-intercalation processes in batteries during charging and discharging are described by governing equations that consist of partial differential equations and ...
Online State and Parameter Estimation for Lithium-ion Batteries Based on a Reduced-order Electrochemical Life Model
Bi, Yalan (2020-04-22)
Inaccurate estimation of the state-of-charge (SOC) and the state-of-health (SOH) may lead to safety issues. Currently, estimations of SOC and SOH that based on electric equivalent circuit models (ECMs) have been widely ...
Optimization of fast charging method based on a reduced order electrochemical model for lithium ion batteries
Yin, Yilin (2020-04-22)
Long charging time is one of the technical barriers that should be overcvome for wide acceptance of electric vehicles (EVs) in the market. The charging time can be simply reduced using increased charging current that ...
A Study of Lateral and Longitudinal Tire Forces Produced on a Deformable Surface with Applied Traction and Braking
McIntyre, David Michael (2015-05-11)
An investigation into the effects that changing tire characteristics have on the production of lateral and longitudinal tire forces was conducted on a test wheel that was subjected to external traction and braking forces. ...
