Battery Modeling

Battery Modeling

The use of mobile devices is often limited by the capacity of the employed batteries. The battery lifetime determines how long one can use a device. Battery modeling can help to predict, and possibly extend this lifetime. Many different battery models have been developed over the years. However, with these models one can only compute lifetimes for specific discharge profiles, and not for worklo...

Modeling Automotive Battery Diagnostics

A utomotive electrical systems are becoming increasingly complex as more and more electrical and electronic equipment is incorporated into new vehicles. With this trend, the growing demand for electrical power is placing greater demands on the automobile’s primary source of electrical energy storage — the lead-acid battery. Whether the vehicle relies on an internal combustion engine, is a hybri...

State-Space Battery Modeling for Smart Battery Management System

Battery Management System (BMS) requires an indefinite accurate model. With an aging model, the lifetime of a battery can be precisely predicted. The mathematical model in terms of state variables is presented in this preliminary work involving smart BMS system. This work is crucial as the state space model is able to mimic the complex dynamic behavior of a battery system. A numerical case stud...

Nonlinear Dynamics Traction Battery Modeling

This chapter presents a method of determining electromotive force (EMF) and battery internal resistance as time functions, which are depicted as functions of state of charge (SOC). The model is based on battery discharge and charge characteristics under different constant currents that are tested by a laboratory experiment. Further the method of determining the battery SOC according to the batt...
