EOBLi

Project Description

The objective of the EOBLi project (Optimal Packaging of Lithium Ion Batteries) is to develop a computerized system to ease the design of battery banks. This is a complex problem, as design goals of ion-lithium battery banks compete among themselves and are hard to organize into a single mathematical expression. In order to solve the optimization problem, the EOBLi project uses advanced multi-objective modeling techniques which, aided by computer intelligence algorithms, allow to create optimal ion-lithium battery bank designs. Computer simulation software along with advanced thermal and useful life models are used in order to obtain the value of the functions.

Origin and Contributions

EOBLi started in 2012 thanks to a Line 1 fund given by CORFO, thus becoming one of four projects by Lithium Innovation Center. A year later, it obtained a three-year grant of a Line 2 fund by CORFO. The project is currently still underway.
