Cell Level Fusing for Lithium Batteries
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.

What is a battery fuse & how does it work?
The design and functionality of the battery fuse protect Li-ion batteries from potentially damaging and dangerous overcurrent and overcharging circumstances. In case overcurrent occurs while using the device, the fuse element will open and cut off the circuit.
How a battery fuses protect against overcurrent?
Overcurrent protection can be achieved by using current fuses or battery fuses. Current fuses protect against overcurrent. On the other hand, a battery fuse is used in a Battery Management System (BMS) as a secondary protection element. In case overcurrent occurs while using the device, the fuse element will open and cut off the circuit.
Why does a DC fuse need to be longer?
For DC voltages above 500 V, the fuse has to be longer to avoid arcing so it is necessary to interrupt a prospective arc. The highest heat is in the middle, and the further the centrepoint is from the terminals the longer the distance for conducting the heat away.
How does an electric car fuse work?
The fuse can also use the airbag signals in the case of an accident to insulate the battery from the car body, using a piston to cut the bus bar. This a complementary function of the airbag to protect the EV electric system. There is a small punching hole in the busbar to make sure the cutting area will be within the marked zone.
How does a pyro fuse work?
The pyro fuse takes a different approach, using the signal from the airbag’s ECU to trigger a pyrotechnic ignitor. This punches through the busbar to physically sever the connection. Mature technology used for airbags can be combined with a fuse to provide isolation in the event of an accident.
How do you know if a battery pack is bad?
Analyze the short circuit clearing time and check if the contactor can withstand until the fuse breaks the circuit. 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.
