Abstract: A current sensor, which is configured to individually detect a current flowing in each of at least two current paths, includes at least two phases. Each phase includes a magnetic field detection element and a pair of first magnetic shield and second magnetic shield. The magnetic field detection element is disposed to face one of the current paths. The magnetic field detection element is configured to detect a magnetic field generated from the one of the current paths and to convert the detected magnetic field into an electric signal. The first magnetic shield and the second magnetic shield are disposed to face each other with the current path and the magnetic field detection element interposed between the first magnetic shield and the second magnetic shield. The first magnetic shield and the second magnetic shield are configured to shield the magnetic field detection element from an external magnetic field.

Abstract: A control module is arranged in alignment with a battery module in a longitudinal direction. The control module includes a busbar, a switch and a current sensor configured to detect electric current flowing through the busbar. The current sensor includes a magneto-electric transducer and a magnetic field suppressor. The magneto-electric transducer is configured to convert a magnetic field, which depends on the electric current flowing through the busbar and passes through the magneto-electric transducer along a plane perpendicular to a height direction, into an electrical signal. The magnetic field suppressor is configured to suppress external magnetic fields from passing through the magneto-electric transducer along the plane perpendicular to the height direction. The switch includes a pair of magnets that are magnetized and opposed to each other in a lateral direction perpendicular to both the longitudinal and height directions. The current sensor is aligned with the magnets in the longitudinal direction.

Abstract: A current detection system includes: first and second magnetic plates arranged in parallel with a predetermined distance; a bus bar for flowing current; and a magneto-electric conversion element converting a lateral direction component of a measurement object magnetic flux, generated by current flowing through the bus bar, to an electric signal. When an external magnetic flux in a lateral direction passes through an accommodation space between the first and second magnetic plates, a trajectory of the external magnetic flux is bent by the first and second magnetic plates, and the accommodation space is divided into a permeable space, through which the external magnetic flux passes, and a non-permeable space, through which the external magnetic flux does not pass. The bus bar is arranged in the accommodation space. The magneto-electric conversion element is arranged in the non-permeable space. The bus bar and the magneto-electric conversion element are lined in the height direction.

Abstract: A current sensor includes a plurality of individual sensors and a wiring case. Each of the individual sensors includes an electrical-conduction member through which a measurement current to be measured flows, a magnetoelectric converter and an insulating sensor housing. The magnetoelectric converter converts a measurement magnetic field caused by a flow of the measurement current into an electric signal. The sensor housing accommodates the electrical-conduction member and the magnetoelectric converter therein. The wiring case is larger than the sensor housing. The wiring case includes an insulating integrated housing in which the plurality of individual sensors is fixed, and an input/output wiring disposed in the integrated housing and electrically connected to the megnetoelectric converter of each of the plurality of individual sensors.
