Thermal Management for Electric Motorcycles—Multi-Scale Modelling and Battery Thermal Design Evaluation by Tao Zhu, Mehmet Kirca, Shilei Zhou, Truong Dinh, Andrew McGordon

“…Particularly, the proposed battery model is structured across the pack–module–cell hierarchy, which makes it capable of distinguishing the thermal state of each individual cell and the cell-to-cell performance variations resulting from temperature effects. The integrated cooling system and multi-scale battery modelling method proposed in this paper allow for a quick comparison of performances between different battery module thermal designs, which is specifically suited for early-stage investigation of different concepts. …”
