Title:
CURRENT DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2015203575
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a current detection device that enables a temperature detection using a current detection element without providing a dedicated component for the temperature detection.SOLUTION: A current detection device 10 houses a magnetic detection element for conducting current detection in its inside. An output Vof a first Hall IC20 being the magnetic detection element and an output Vof a second Hall IC21 being the magnetic detection element are input to an arithmetic processing unit 30. The arithmetic processing unit 30 calculates a temperature of surroundings (battery cable 3) of an electric conductor on the basis of temperature drift coefficients of the first Hall IC20 and the second Hall IC21, output voltages Vand Vof the first Hall IC20 and the second Hall IC21 and the like.
