Battery state estimation: methods and models

Batteries of various types are of vital importance for storing intermittent renewable energy for stationary and mobile applications.

Managing the batteries and maintaining their performance requires knowledge of key parameters such as charge, power output, and health.

State estimation estimates the electrical properties of a system using measurements and modelling.

Numerous methods are available. This work conveys them in detail, covering all parameters relevant for a battery management system with experimental results and verification.
