Abstract: A wire harness attachment structure for a vehicle seat capable of being flipped up from a usage position where the vehicle seat is disposed on a floor to a storage position where the vehicle seat is disposed along a standing wall portion of a vehicle body, includes: a rotation shaft that couples the vehicle seat to the standing wall portion; a guide member including a pair of wall portions arranged to face each other in an axial direction of the rotation shaft, and being partly opened in a radial direction between the wall portions; and a wire harness that electrically couples the vehicle seat and the vehicle body. A portion of the wire harness is disposed between the wall portions and does not come into contact with a member other than the wall portions when the vehicle seat is flipped up from the usage position to the storage position.

Abstract: A cell system includes a laminated battery, a plurality of battery cells being laminated in the laminated battery, a first switch connected to a positive electrode of the laminated battery and configured to switch connection to the positive electrode to a shut-off state, and a second switch connected to a negative electrode of the laminated battery and configured to switch connection to the negative electrode to a shut-off state. Furthermore, the cell system includes a circuit to be connected at least either between the positive electrode and the first switch or between the negative electrode and the second switch; and a controller configured to shift control timings of the first switch and the second switch from the shut-off state to a connected state according to an electrical capacitance generated between the positive electrode and the negative electrode.
