Abstract: In a connector, each of housings of a socket and a header serving as connector parts includes: a terminal holder extending in a first direction and includes a terminal section of the associated connector part; and a side wall connector extending in a second direction intersecting the first direction, and connected to one end of the terminal holder of the associated connector part in the first direction. The shield member includes a first portion on the side wall connector, and a second portion aligned with the terminal holder of the connector part in the second direction. The socket and the header are inserted into each other in a third direction intersecting the first and second directions. The second portion of at least one of the shield members includes a shield bent portion with a curved portion curving toward the other connector part to be inserted.

Abstract: Controller of power storage pack performs communication for authentication with controller of an electric moving body according to the pattern of a current flowing through a power line in a state where power storage pack is mounted to electric moving body. Controller of power storage pack measures contact resistance between power storage pack and the electric moving body based on voltage of the power line on power storage pack side, voltage of the power line on the electric moving body side received from controller of the electric moving body, and current when communication for authentication is performed according to the pattern of a current flowing through the power line.

Abstract: An arc detection system includes a first obtainment unit, a second obtainment unit, and a determination unit. The first obtainment unit obtains a measurement result of current flowing in a power line to which power is supplied from a power supply or a measurement result of voltage in the power line. The second obtainment unit obtains operation information about operation of a device connected to the power line. The determination unit determines whether or not an arc fault has occurred in the power line based on the measurement result obtained by the first obtainment unit and the operation information obtained by the second obtainment unit.

Abstract: A resin composition contains a curable resin. A minimum value (Min) of loss tangent (tan δ=E″/E′) of a cured product of the resin composition is equal to or greater than 0.04. The loss tangent is a ratio of a loss modulus (E″) of the cured product of the resin composition to a storage modulus (E′) thereof. The loss modulus (E″), the storage modulus (E′), and the loss tangent (tan δ=E″/E′) are obtained by dynamic mechanical analysis at a temperature equal to or higher than 100° C. and equal to or lower than 200° C.

Abstract: A solid electrolytic capacitor element included in a solid electrolytic capacitor includes an anode foil that contains element Al and includes a porous part at least in a surface layer of the anode foil, a dielectric layer that covers at least a portion of a surface of the anode foil, and a solid electrolyte that covers at least a portion of the dielectric layer. The solid electrolyte contains element S, and the solid electrolyte has a first part filled in voids in the porous part in the anode foil having the dielectric layer and a second part that protrudes from the main surface of the anode foil having the dielectric layer. In elemental mapping of a cross section of the porous part using an electron probe microanalyzer, the presence ratio of the element S is 0.5% or more when the presence ratio of the element Al is taken as 100%.

Abstract: In a battery abnormality detection system, a data acquirer acquires voltage data and current data of each cell of a battery pack having a plurality of cells connected in series or of each parallel cell block of a battery pack having serially connected parallel cell blocks having a plurality of cells connected in parallel. The abnormality detector detects a cell or parallel cell block in an abnormal state on the basis of a relative voltage change amount among the plurality of cells or among the plurality of parallel cell blocks in a constant voltage charging period.
