Document Type and Number:
Japanese Patent JP6167917
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a secondary battery inspection method and a secondary battery inspection device capable of promptly inspecting whether a fine short-circuit occurs to a secondary battery.SOLUTION: A secondary battery inspection method of the present invention includes: measuring a magnetic field intensity of a secondary battery 701 in a state of opening a cathode and an anode of the secondary battery 701; detecting a magnetic field 703 generated by a current flowing in the secondary battery 701 on the basis of the measured magnetic field intensity of the secondary battery 701; and determining that a short-circuit occurs in the secondary battery 701 if the magnetic field 703 generated by the current is detected. Furthermore, a secondary battery inspection device 100 of the present invention includes: a magnetic sensor 101 measuring the magnetic field intensity of the secondary battery 701; a magnetic field detection unit 102 detecting the magnetic field 703 generated by a current flowing in the secondary battery 701 on the basis of the magnetic field intensity measured by the magnetic sensor 101; and a short-circuit determination unit 103 determining that a short-circuit occurs in the secondary battery 701 if the magnetic field detection unit 102 detects the magnetic field 703 generated by the current.
