PURPOSE: A battery current measurement device is provided to simplify a manufacturing process by not requiring a separate fixing unit and to reduce manufacturing cost. CONSTITUTION: A battery current measurement device includes a clamp (100), a busbar (110), a magnetic core (400) and a magnetic field sensor (310). The clamp includes a terminal hole in which a batter terminal is inserted. The busbar passes current by being electrically connected to the clamp. The magnetic core is formed to surround at least a part of the busbar in the longitudinal direction and amplifies a magnetic field generated by the current passing through the busbar. The magnetic sensor detects the magnetic field amplified by the magnetic core. |
