A Comparative Analysis of Copper, Nickel and Cu Ni Composite busbars in Lithium Battery Packs Why Battery busbars Deserve More Attention Battery busbars are often overshadowed by battery chemistry, BMS design, or thermal strategies. Yet they are essential in defining how efficiently current moves across cells and modules. Their electrical, thermal, and mechanical behaviour can … Read more

Cell Busbar Thermal Model

cell busbar thermal model

Can we build a quite simple cell busbar thermal model? First thoughts are whether we can make some simple approximations and hence create a spreadsheet model. We have a current [I] flow through the busbar (orange). The busbar has a resistance defined by it’s resistivity, cross-sectional area and length. Hence we can calculate the heating … Read more
