Abstract
Lithium-ion batteries, unlike other chemistries, may need the voltage of every cell monitored. This may employ a wiring harness or interconnect board that connects the leads of each cell to battery monitoring electronics. These leads can be protected from each other by one or more methods including physical segregation, insulation, and fusing. If a fuse is used it can be located as close as possible to the terminal of the cell. The fuse can be located inside the sealed compartment of the cell itself. The leads would be passed out of the cell in a second location allowing the use of alternative sense lead wiring harnesses or interconnect board designs that save on packaging cost and volume. By locating the fuse inside the cell, design and validation efforts involved in placing a fuse inline with the wiring harness are eliminated.
