BATTERY SYSTEM MODELLING

Accurate simulations of batteries will give ABOVE: To advance current models and (ICL) us the ability to design advanced batteries develop design tools which can accurately will lead a consortium of six without the cost of creating numerous predict the performance and lifetime of prototypes to test every new material, or existing and future batteries requires a other university and 17 new type and configuration of the cells fully integrated and tightly coordinated which make up a pack. Simulations also programme, drawing together the key industry partners to equip offer valuable insight into how existing modelling capabilities into a multi-scale industry and academia with materials work, enabling us to identify the approach, across length and time scales. limiting processes and develop rational new software tools to strategies to overcome them or design understand and predict new materials, leading to significant improvements of battery performance and ensuring that the models developed are battery performance, by lifetime. Models for control will also scientifically rigorous, computationally enable us to extend the lifetime and/or efficient and experimentally validated in connecting understanding of performance and reduce the cost of parallel, to maintain a high degree of existing and future packs. usefulness and accuracy. The first battery materials at the challenges to be tackled include fast- atomic level all the way up to To simulate an EV battery pack, we need to charging of batteries, low temperature consider a range of length scales, from the operation and thermal management of an assembled battery pack. nanoscale, where atoms interact, right up cells within battery packs. to the macroscale of a complete pack and its electronic control mechanisms.
