Studying lithium-ion battery packs cooling system using water-nanofluids composition

In this study, the Li-ion batteries temperature increase during the discharge process was measured empirically and evaluated using numerical simulation. Moreover, the battery packs cooling using the water, air and water-nano composition fluids such as water-alumina, water-copper oxide, and water-gold was studied through numerical simulation. Accordingly, the battery cooling was simulated by CFD...

Modeling The Lithium-ion Battery

Estimation of Lithium-ion Concentrations in Both Electrodes of a Lithium-ion Battery Cell

For control and estimation tasks in battery management systems, the benchmark Li-ion cell electrochemical pseudotwo-dimensional (P2D) model is often reduced to the Single Particle Model (SPM). The original SPM consists of two electrodes approximated as spherical particles with spatially distributed Li-ion concentration. However, the Li-ion concentration states in these two-electrode models are ...

Experimental modal analysis of lithium-ion pouch cells

If future electric and hybrid electric vehicle batteries are to be designed such that the impact of vibration induced resonance is minimized, engineers tasked with the design of the vehicle's energy storage system must have a rigorous understanding of key system attributes such as the natural frequencies of the cell, the level of damping present and the mode shapes induced within the battery un...
