Base vs Side Cooling Cylindrical Cells

cylindrical cell base versus end cooling

Base vs side cooling of cylindrical cells is often brought up in online discussions and in many OEMs designing battery packs. We looked at this before within Thermal Conduction in a Cell, however, I think it is worth expanding this topic. The Tesla design cools the side of the cell and the Lucid Motors cools … Read more

Cell Temperature Gradient

A cell temperature gradient can limit performance and the lifetime of the cell. Therefore, it is important to design the battery to minimise the temperature gradient. This can be particularly difficult in the case of high performance battery packs. The maximum temperature differential in a cell is normally specified as ~2°C to minimise the degradation … Read more

Passive Cooling

Passive battery cooling

Passive cooling means the battery cell or pack is not actively cooled, instead it relies on heat conduction, radiation and convection. This heat transfer will apply in both directions, to and from the environment. Passive cooling should be the starting assumption for all battery pack designs, the drive cycles and user cases could set requirements … Read more

Smart Battery Development

smart battery design

Prof James Marco WMG Energy Group Significant advances have been made in recent years in our understanding of the electrochemical performance of lithium-ion batteries (LIBs), their degradation, safety, manufacturability and recyclability – in part, through innovations in experimental methods and mathematical modelling. WMG is at the heart of this research through our involvement in projects … Read more
