ABSTRACT
Electrochemical batteries represent the highest part of all storage applications by their numbers, from portable systems like mobile phones and computers to higher capacities in transportation, to stationary systems in connection with renewable energy sources.
The different available technologies with their electrochemical phenomenology are presented, together with methods for modeling and simulation. Equivalent schemes are presented, with models of the extracted charges allowing the estimation of the state of charge and also thermal models. Further, multiphysics modeling is presented, through the example of a vanadium redox flow battery. The importance of the power consumption of the auxiliaries is also shown.
The chapter is completed with a description of the BMS (battery management system).
Battery-aging phenomena are also described with cycling aging models and calendric aging models.
Dedicated to electrochemical storage, the chapter includes an exercise where the electrical energy design is presented, together with the thermal behavior of the battery case in both natural convection and forced ventilation cooling.
