Description

The importance of the Lithium-ion (li-ion) batteries is booming and after dominating the portable electronics applications, they are entering into new sectors like grid support applications and propelling of the electric vehicles. The penetration of renewables in the power system is considered to significantly increase in near future; thus, batteries can play a crucial role in the reliable and cost efficient grid integration of intermittent energy sources. Besides, the grid support applications, li-ion batteries are playing a major role in the automotive market. The use of batteries in automotive applications is a promising option in order to replace the internal combustion engine cars with ideally, zero emissions vehicles (full electric vehicles), or with controlled emission vehicles (hybrid electric vehicles and plug-in hybrid electric vehicles).
The objective of this tutorial is to provide the audience with an extensive overview of the lithium-ion battery energy storage technology, its operating principles, advantages and drawbacks, system integration issues and requirements. Moreover, a part of the tutorial is dedicated to the performance modelling of the lithium-ion batteries. Different modelling methods will be introduced and their characteristics (e.g., accuracy, complexity etc.) will be assessed.
On the other hand, new battery applications require new power electronics solutions in order to assure lithium-ion battery pack safety, high-efficiency and reliable operation. Power electronics play three important roles in the battery applications: charge/discharge management, battery cell balancing, and safety protection. In consequence, this tutorial will provide extensive state of the art on battery management systems objectives and functionalities. This will be supplemented by an overview of power electronics solutions for battery charge/discharge management in the stationary and e-mobility applications.
At last but not at least, new solutions will be discussed as the so-called Smart Modular Battery Packages. In this topology, individual battery cells are not connected directly in series, but through individual DC-DC converters allowing flexibility in the individual loading of each cell. This provides many advantages such as more compact design due to the integration of battery management system (BMS) and battery charger by means of DC-DC converters, improved battery pack energy management and lifetime, and possibility of bypassing under-performing or failing battery cells in battery packs.
