Energetical Modeling of Lithium-Ion Batteries
2007 IEEE Industry Applications Annual Meeting, 2007All electrochemical batteries are characterized by an electrical behavior which depends on temperature, state of charge and current. In the case of lithium-ion accumulators, the energetical behavior is moreover deeply marked by line effects, due to the porosity of both electrodes. This paper deals with investigations on accurate energetical modeling of

A lithium-ion battery modeling for a HIL-battery simulator
2013 International Conference on Computer, Control, Informatics and Its Applications (IC3INA), 2013A battery simulator is needed to test battery management systems (BMS) for electric vehicles. A new battery simulator called a Hardware in Loop (HIL)-battery simulator is build. In order to facilitate the electric battery model part of the HIL-battery simulator, a simple and accurate equivalent circuit model for LiFePO 4 batteries is defined.

Sensitivity analysis of lithium-ion battery model to battery parameters
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013Different models have been proposed so far to represent the dynamic characteristics of batteries. These models contain a number of parameters and each of them represents an internal characteristic of the battery. Since the battery is an entity that works based on many electrochemical reactions, the battery parameters are subject to change due to ...

Modeling and SOC estimation of LiFePO4 battery
2016 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2016In order to estimate the state of charge (SOC) of LiFePO4 battery more accurately, an improved Extended Kalman Filter (EFK) algorithm is proposed to estimate the parameters in the least squared identification model. A second-order RC equivalent circuit is used as the battery model, and an additive term is introduced into the state equation for real ...

The function of a battery is to supply electrical energy at a rate sufficient to power the device it drives. Since power is the product of current and terminal voltage, the ideal battery performance model will project these quantities mathematically over the entire range of conditions likely to be encountered in the lifetime of the battery.
