Abstract

Battery management system monitors and mitigates the operation of battery cells and stacks and is important for battery safety and reliability. This paper presents a dual-objective optimal charging strategy for two types of Li-ion batteries, which considers the conflict objectives of charging time and charging loss. The battery models developed in a prior research are used in the charging optimization. The influences of the charging voltage threshold, temperature, and health status on the charging results are analyzed for both lithium nickel manganese cobalt oxide (LiNMC) and lithium iron phosphate (LiFePO4) batteries. A comparison with the charging results based on the models that cannot describe the entire battery dynamics is also performed. (C) 2013 Elsevier B.V. All rights reserved.
