Efficient electrochemical model for lithium-ion cells
Afshar, Sepideh; Morris, Kirsten; Khajepour, Amir (2017-09-12)Lithium-ion batteries are used to store energy in electric vehicles. Physical models based on electro-chemistry accurately predict the cell dynamics, in particular the state of charge. However, these models are nonlinear ... -
Lithium-Ion battery SOC estimation
Afshar, Sepideh (University of Waterloo, 2017-01-23)Lithium-ion batteries are frequently used in Hybrid electric vehicles (HEVs), which are taking the place of gas-engine vehicles. An important but not measurable quantity in HEVs is the amount of charge remaining in the ... -
A modified sliding-mode observer design with application to diffusion equation
Afshar, Sepideh; Morris, Kirsten; Khajepour, Amir (Taylor and Francis, 2018-02-27)In many physical systems, the system's full state cannot be measured. An observer is designed to reconstruct the state from measurements. Disturbances often contribute to the dynamics of the system, and the designed observer ...
