Cell-level fusing works by installing a fuse at the cell level, which will automatically cut off power to the battery if it exceeds a certain temperature or voltage. This helps to prevent dangerous situations such as explosions or fires caused by overheating or overcharging.
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.
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.
Cell level fusing is just one of many safety measures that can be used in lithium-ion batteries. Other measures include thermal management, which helps to keep the battery at a safe temperature, and overcharge protection, which prevents the battery from being charged too much.
For the longest time, wire bonding was the most viable option for cost-effective implementation of cell-level fusing. It’s a process that uses ultra-thin wires that function as a fuse to connect the battery cells to a bus bar. This method is relatively inexpensive but it can be rather difficult to implement.
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”.
The reason there are multiple fuses rather than one big one are that so current flows equally from each cell in the parallel string. If there was just one big fuse in the center, the middle battery would be providing the most …
