Degradation Conscious Li-ion Battery Modelling and Management
Renewable power sources have been recently widely deployed worldwide in the pursuit of low-carbon electricity generation. In Australia, the number of households equipped with rooftop PV systems has reached 1.74 million in 2017, about 1/5 of all residences. However, with increasing distributed generation penetration, the intermittent nature of these sources poses significant technical challenges to the distribution network, such as voltage fluctuations and unbalance, which is hampering further take-up.
Fortunately, the growing adoption of distributed energy storage, mostly using lithium-ion (Li-ion) batteries, can alleviate and even completely overcome these
challenges. However, the modelling and production of Li-ion batteries is not yet mature. High prices coupled with uncertain calendar and cycle lifetime is holding back widespread adoption by the general public. In this talk, we will discuss how Li-ion battery electrochemical models incorporating battery degradation phenomena can be used in the management of modern distribution systems. Systematic approaches to predict the degradation of
grid-connected lithium-ion batteries based on high-performance physics-based mathematical models will be presented. Such first-principle models clearly explain the major degradation mechanisms of lithium batteries from the perspective of electrochemistry and thermodynamics. The state-of-the-art design of advanced battery management systems (ABMSs) aiming to achieve overall technical and economic benefits for the renewable-storage systems will be discussed.
