The NUS Computational Combustion and Energy Group is developing a numerical heat transfer and fluid dynamics solver BatteryFoam. It incorporates various thermal-electrical-chemical models to account for the different unsteady processes in lithium-ion battery based on open-source OpenFOAM code. We aim to use it to computationally study thermal management, thermal runaway and fire hazards of lithium-ion battery for various applications, such as electric cars and portable mobile devices. Multi-dimensional battery simulations can be undertaken with BatteryFoam. This will provide accurate and comprehensive information inside the battery under normal and abuse conditions, toward digital twins of Li-ion battery thermal management.

This work for BatteryFOAM development is undertaken by the PhD student DING Yan.

Applications: battery thermal management and safety problems, e.g., battery thermal runaway and fires.




We are also developing different battery modelling platform based on various commercial softwares (e.g., ANSYS Fluent and COMSOL) to meet the versatile research for lithium ion batteries, and some of the results can be found below:
