Check the contactor-fuse coordination for normal operation, overloads and failure currents. The fuses in a battery pack protect the battery and the other electrical components against high currents. There are special off-the-shelf components similar to 12V starter battery fuses. However, EV fuses are rated for high voltage and traction currents.
Fuses are protection devices that protect electrical circuits against undesired high currents. We can use passive fuses and pyro fuses in battery design.
Today, there is a more efficient solution in the form of Batty Hookup cell-level fuse sheets. These nickel sheets are designed to fuse every cell point, making it easy to build a battery pack from 18650 cells with automatic fusing. The sheets are made by cutting specific shapes into the nickel where the cell is usually welded.
The fuses in a battery pack protect the battery and the other electrical components against high currents. There are special off-the-shelf components similar to 12V starter battery fuses. However, EV fuses are rated for high voltage and traction currents. The page has a list of EV fuse manufacturers.
In a cylindrical cell there is normally two layers of fuse, the CID and a ribbon connection between the jelly roll anode and cathode to the -ve and +ve terminals respectively. The ribbon connection is quite thin and hence will break at a given current.
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 external fuses are used. Fuses are protection devices that protect electrical circuits against undesired high currents.

Live ChatThis is all that matters. You need to ensure that the fuse is on the only pathway to the source that you''re trying to isolate. If you put the fuse on negative and have anything else connected to that negative terminal before the fuse, assuming it''s "ground", you''re going to have problems. That''s a very common problem with low-side MOSFETs.
