In general battery cells are charged/discharged using constant current or constant power expressed as C-Rates and P-Rates respectively. We are developing a single cell-level Li-Ion battery model in order to simulate the performance and the physicochemical phenomena under power ... En savoir plus

With the Creation, roll-out, and maintenance of COMSOL Simulation apps, the role of simulation engineers and departments is expanding to include responsibilities similar to those of software developers. Within our department, we have undergone this transformation and will share the key ... En savoir plus

Freeze-dried (lyophilized) drug products offer extended shelf life and improved drug stability within a range of combination products including autoinjectors and pre-filled syringes. A key step in the use of combination products is the reconstitution of the freeze-dried drug product (DP) ... En savoir plus

The purpose of this work is to show whether an important difference in Lithium solid concentration and electrolyte concentration can be observed in a Lithium-ion battery model, when considering either the Butler-Volmer kinetics or the Tafel kinetics for describing the electrode kinetics ...

The adoption of micro- and nanostructured electrodes is a promising technique to improve the performance of Li-ion battery, which increases the electrode surface area and improves the efficiency of ion exchange between the electrode and electrolyte. This performance improvement is ... En savoir plus

A new method is proposed to study battery thermal behavior under nature convection condition, especially focusing on temperature rising and inhomogeneity of battery. Using porous electrode theory, an electrochemical and homogenization heat source thermal coupling model and an ... En savoir plus

As the global use of COMSOL® apps continues to grow, many developers are seeking practical and secure methods to protect their applications and control their usage. While traditional paid software often relies on license keys, there has been a lack of simple and flexible tools tailored ... En savoir plus

This work is to present an implementation of COMSOL with MATLAB® [1] for the liquid cooling system of a battery pack based on the physics in COMSOL. The m.file of a model of battery module from COMSOL 4.2 is exported and modified to run in MATLAB®, as well as is managed by using another ... En savoir plus
