Sensor based in-operando lithium-ion battery monitoring in dynamic service environment

Monitoring and Health prognosis of Lithium-Ion battery system

This work discusses new approach to Lithium-Ion battery health monitoring and lifetime prediction dedicated to use in off-grid application. First part of a study contains results of testing single cell in contest to notice the degradation effect. To simulate work-conditions LabView program was written with association of hardware for control of experimental rig.The biggest issue of testing life...

Lithium-ion Battery Electrothermal Model, Parameter Estimation, and Simulation Environment

The market for lithium-ion batteries is growing exponentially. The performance of battery cells is growing due to improving production technology, but market request is growing even more rapidly. Modeling and characterization of single cells and an efficient simulation environment is fundamental for the development of an efficient battery management system. The present work is devoted to defini...

Model-based Sensor Fault Diagnosis of a Lithium-ion Battery in Electric Vehicles

The battery critical functions such as State-of-Charge (SoC) and State-of-Health (SoH) estimations, over-current, and over-/under-voltage protections mainly depend on current and voltage sensor measurements. Therefore, it is imperative to develop a reliable sensor fault diagnosis scheme to guarantee the battery performance, safety and life. This paper presents a systematic model-based fault dia...

Dynamic Lithium-Ion Battery Model for System Simulation

We present here a complete dynamic model of a lithium ion battery that is suitable for virtual-prototyping of portable battery-powered systems. The model accounts for nonlinear equilibrium potentials, rateand temperature-dependencies, thermal effects and response to transient power demand. The model is based on publicly available data such as the manufacturers’ data sheets. The Sony US18650 is ...
