from chemistry to pack
Cell temperature sensing is a critical function of any Battery Management System (BMS) this is because the cell temperature needs to be kept within a band to maintain safe operation. This band is narrower still to maintain the lifetime of the cell and hence reduce ageing. Cell Temperature For each cell the manufacturer will define … Read more
There can be a number of reasons to do an Emergency Shutdown of a battery pack and a number of approaches to this. Hence interesting to layout and discuss this topic. It should be noted that we are discussing the BMS opening the contactors. The main reasons for an emergency shutdown are: Each of these … Read more
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
Batteries are the heart of an Electric Vehicle but the Battery Management System is more like the brain which keeps the Heart pumping out electricity to the Motor safely and at required output. Electric
