Battery protection circuit including battery management system and fuse-blowing circuit and method of controlling same

摘要

A battery protection circuit and a method of controlling the same. The battery protection circuit includes a fuse blowing path connected in parallel to at least a portion of a high-current path between a battery and a terminal unit, the high-current path having a fuse therein, and a fuse current control switch in the fuse blowing path, the fuse current control switch controlling a current flow along the fuse blowing path. The battery protection circuit may completely blow the fuse when a battery malfunctions.

主权项

1. A battery protection circuit, comprising:
a fuse blowing path connected in parallel to at least a portion of a high-current path between a battery and a terminal unit, the high-current path having a fuse therein; a fuse current control switch in the fuse blowing path, the fuse current control switch controlling a current flow along the fuse blowing path; a fuse blowing switch between the fuse and ground, the fuse blowing switch controlling blowing of the fuse; and a battery management system to generate a switch control signal and to apply the switch control signal to the fuse current control switch and the fuse blowing switch, the switch control signal to turn on the fuse current control switch and the fuse blowing switch at a same time period when the battery malfunctions.
