Cell level fusing is a technology that uses a fuse to connect each individual cell of a lithium-ion battery together to prevent overcharging, over-discharging, and overheating. This ensures that if one cell becomes damaged, it will be much less likely to cause a chain reaction that could lead to a fire or explosion.

Also, a method of assessing the fire risk of battery packs by applying the interquartile range (IQR) filter to real-time data obtained from the electrically measured factors of battery packs is proposed. The feasibility of the proposed method is verified by the experiment using the specifications of the high-capacity battery packs used for railway vehicles.
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 external fuses are used.

Therefore, a method that can reduce the number of detected cells is urgently needed. A low-redundancy battery pack diagnosis method is proposed to address the data redundancy issue in electric vehicle battery pack fault detection of ISC and VC. The fault diagnosis efficiency can be improved dramatically if the fault diagnosis process is executed only in abnormal cells. Via

Cell-level fusing is a technique that helps improve the safety and reliability of lithium-ion batteries by installing a fuse at the cell level. This fuse automatically cuts off power if the battery exceeds a certain temperature or voltage, preventing potential dangers such as overheating, overcharging, and the possibility of explosions or fires.

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 electrical path to pull up the battery pack VCC passes through the host capacitance from Pack+ to Pack–, through a substrate diode in the host interface driver from VSS to the commu-nication or interface line, and through a substrate diode from this line to VCC in the battery-pack circuitry. The complete path is shown in Fig. 6.
The conclusion from this paper is that “the module fuse operates over 120 times faster than the cell fuse based on the same SOC conditions, and the quantity of electric charge in the module fuse is over 110 times smaller than in the cell fuse in the case of a short-circuit fault”.
We can use passive fuses and pyro fuses in battery design. Select a fuse rated double as continuous current (e.g. initially take 400A fuse for 200A continuous current) and draw the load profile next to 50% of the fuse breaking current-time chart to check if pulse currents can be carried by the fuse without aging.
