A design for the thermal management of the media used for packing Li-ion batteries used in hybrid and electric vehicles has been developed. The design satisfies all thermal and physical issues relating to the battery packs used in vehicles such as operating temperature range and volume, and, should increase battery life cycle and charge and discharge performances. Particular attention was ...

The Electrical Double Layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy, and Chapman-Stern) are numerically solved for a flat surface electrode in the 3D Electrostatics application mode of COMSOL Multiphysics® 3.5a. The values of the electric ...

The proposed State of Charge (SOC) governed fast charging method for secondary lithium based batteries charges a battery many times faster than the normal Constant Current-Constant Voltage (CC-CV) charging and reduces the side-effects generally accompanied by various fast charging methods. The proposed charging algorithm takes into account the varying internal impedance of the battery at ...

In this work the coupled electrochemical-thermal model for a lithium-ion battery (LIB) based on porous electrode theory has been extended with contributions coming from exothermic side reactions based on an Arrhenius law to model abuse mechanisms, which could lead to a thermal runaway. These extensions have been modeled with a constant fuel model and for specified current profiles and exterior ...

This project modeled an industrial chromium plating process for automotive components. The process was modeled via the COMSOL Multiphysics® Electrodeposition Module. The simulation examined the effect of solution conductivity, electrode spacing, and anode height utilizing a factorial design approach. A sensitivity analysis was used to study the effect of these variables on the thickness value at ...

A lithium-ion battery comprises of two intercalating electrodes separated by a membrane, sandwiched between aluminum and copper current collecting plates. The battery performance depends upon several parameters and its operating conditions. In this work we developed a model for a lithium iron phosphate battery and validated our results with experimental charge-discharge curves. We however note ...

Low cost high energy density batteries that can be charged and discharged rapidly are required in a number of applications. Tapping energy from renewal resources such as solar, wind and tide requires rapidly generated energy to be first stored and then used round the clock. Storing energy of a moving vehicle as it slows down and recovering it to accelerate the vehicle later can significantly ...

The existing lithium ion battery model in COMSOL’s Multiphysics software is extended to include the thermal effects. The thermal behavior of a lithium ion battery is studied during the galvanostatic discharge process with and without a pulse. The existing lithium ion battery model in COMSOL 3.5a is extended by adding an energy balance and the temperature dependence of properties of ...
