Cell Level Fusing for Lithium Batteries
Cell level fusing is a safety measure for lithium-ion batteries that provides a physical barrier to prevent overcharging and overheating. 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.

What is cell level fusing in a lithium ion battery?
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.
What are battery fuses?
Battery fuses are designed to protect Lithium-ion (Li-ion) batteries from potentially damaging and dangerous overcurrent and overcharging events. The devices safeguard components, equipment, and people from risk of fire and electric shock. Overcurrent protection can be achieved by using current fuses or battery fuses.
Is wire bonding a viable option for fusing lithium-ion batteries?
These fuse wires are designed to activate at a specific current or temperature threshold, providing an additional layer of safety to your project. Overall, wire bonding is a viable option for implementing cell-level fusing in lithium-ion batteries, but it has a massive learning curve and again, requires specific, specialized equipment.
Would a 200A Mega fuse protect a lithium battery?
Based on the specs I would assume a 200a inline mega fuse would protect the 200ah lithium battery (and cable--at 35mm2 with a 1m run), would this assumption be correct? Not really, as you have not advised what type of battery limits the Lithium battery has. and thus without all the information its not possible to advise you.
How many amps does a lithium ion battery need?
Watts divided by volts equals amps. So, that means your circuit will require 41.6 amps. Lithium-ion batteries can store quite a bit of energy. To be able to access that energy, a conductor must be used to connect the cells together in the best way for a given project. Nickel is the preferred conductor to connect lithium-ion battery cells together.
Are EV fuses rated for high voltage?
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.
