On-board monitoring of 2-D spatially-resolved temperatures in cylindrical lithium-ion batteries: Part I. Low-order thermal modelling
Robert R. Richardson, Shi Zhao, David A. Howey
Estimating the temperature distribution within Li-ion batteries during operation is critical for safety and control purposes. Although existing control-oriented thermal models - su…
On-board monitoring of 2-D spatially-resolved temperatures in cylindrical lithium-ion batteries: Part II. State estimation via impedance-based temperature sensing
Robert R. Richardson, Shi Zhao, David A. Howey
Impedance-based temperature detection (ITD) is a promising approach for rapid estimation of internal cell temperature based on the correlation between temperature and electrochemic…
Global sensitivity analysis of battery equivalent circuit model parameters
Shi Zhao, David A. Howey
This paper considers one of the most commonly used equivalent circuit models (ECMs) for lithium-ion batteries and investigates the sensitivity of the model output to changes of mod…
Circuit Synthesis of Electrochemical Supercapacitor Models
Ross Drummond, Shi Zhao, David A. Howey +1
This paper is concerned with the synthesis of RC electrical circuits from physics-based supercapacitor models describing conservation and diffusion relationships. The proposed synt…
Observability analysis and state estimation of lithium-ion batteries in the presence of sensor biases
Shi Zhao, Stephen R. Duncan, David A. Howey
This paper investigates the observability of one of the most commonly used equivalent circuit models (ECMs) for lithium-ion batteries and presents a method to estimate the state of…
