Thermal Analysis of Li-Ion Cells for Safety Simulation

TUM CREATE is a research programme sponsored by the Singaporean National Research Foundation (NRF). It is jointly performed by Technische Universität München (TUM, Munich) and Nanyang Technological University (NTU, Singapore), aiming at innovative technologies and future transportation concepts, that match the challenging requirements of fast growing and continuously changing tropical megacities. For electric vehicles (EV) energy storage is still a common known problem. In tropical climate conditions one of the most essential issues to consider is the thermal behaviour of the battery cell. High temperatures deplete battery lifetime significantly and are furthermore critical for battery safety [1]. Therefore, besides active cooling systems for the battery pack, the authors’ approach is to make the single cells as intelligent as possible by applying different temperature monitoring and simulation techniques.
