from chemistry to pack
When we connect cells in parallel to increase the capacity we might also want cell level fusing. This fusing being by definition designed to disconnect a cell that for some reason is sinking or delivering high currents. The fusing can be inside the cell and sealed or external to the cell, sometimes both internal and … Read more
The fuse selection procedure is very similar to contactor selection and complementary parameters help to select EV fuses. Fuse datasheets include breaking current-time characteristics. Some of the fuse manufacturers also provide thermal and mechanical characteristics. Thermal and Mechanical Specifications Fuses are simple busbars with melting elements inside. Therefore, the initial step is always to define … Read more
The basics of fuses are protection devices that protect electrical circuits against undesired high currents. We can use passive fuses and pyro fuses in battery design. Passive Fuse Passive fuses break the circuit only as a result of high currents for a certain time. They have a weak internal structure as a melting element. During … Read more
The electrical design of the battery pack is associated with fundamental electrical elements. These elements are Busbars, Contactors, Fuses, pre-charge resistors, current sensors, HV (High Voltage) and LV (Low Voltage) Connectors, and wiring harnesses. Busbars are electrically conductive materials that maintain current flow from the cells to the external electrical loads. Aluminum and copper are … Read more
