Abstract: An object of the present disclosure is to provide a doping method in which the status of the progress of a main reaction can be estimated in the lithium carbonate decomposition-type doping step of a nonaqueous lithium power storage element. The separation method, the doping method, and the doping apparatus according to the present disclosure include calculating a capacitor current density iC and an electrode reaction current density iR based on voltage and current of a cell that are measured during doping of the cell.

Abstract: A gasket for sealing a gap between a through hole formed on a wall body and a pipe to be inserted into the through hole, the gasket being provided for the pipe and made of tubular elastic material, the gasket having an inner circumferential lip portion which elastically contacts an outer circumferential face of the pipe; and an outer circumferential lip portion which elastically contacts an inner circumferential face of the through hole; an inner seal area on an inner circumferential side where the inner circumferential lip portion is provided is located at a position so that the inner seal area does not overlap in a radial direction with an outer seal area of an outer circumferential side where the outer circumferential lip portion is provided.

Abstract: A structure of mounting an electric device in a front compartment of a vehicle is disclosed. The structure may include: a casing being divided into a first and a second casing; a first and a second through hole provided in the first casing; a first and a second fixing hole provided in the second casing; a first fastening member passing through the first through hole and fixed to the first fixing hole; and a second fastening member passing through the second through hole and fixed to the second fixing hole. The first through hole is located at a far side of the first casing with a vehicle's center line and located at a front half of the first casing. The second through hole is located at a closer side and a rear half of the first casing.

Abstract: A vehicle includes a motor housing accommodating motors for driving wheels, and a power control unit fixed on the motor housing. The power control unit includes: a stacked unit in which multiple power modules accommodating power semiconductor elements for electric power conversion and multiple coolers are stacked; and reactors. The stacked unit is disposed in the case of the power control unit such that the stacking direction of the power modules and the coolers is directed toward the vehicle-longitudinal direction. The reactors are disposed in the case so as not to overlap with the stacked unit as viewed from the stacking direction.

Abstract: In an in-vehicle structure described in the present specification, an electric-power converter is fixed onto a transaxle and positioned in front of a cowl top. The electric-power converter includes a capacitor configured to restrain a high-frequency fluctuation in a voltage of electric power supplied from a battery, and a discharge circuit configured to discharge the capacitor. A connector (a signal connector) to which a wiring harness for communication of a discharge instruction signal to operate the discharge circuit at a time of a collision is connected is provided on a side face of the electric-power converter, the side face of the electric-power converter being facing in a vehicle width direction.

Abstract: An electric power converter (10) is divided into a main casing (10a) and an auxiliary casing (10b). The main casing (10a) contains a high-voltage circuit (28, 29) through which electric power for driving a motor (83) flows. The auxiliary casing (10b) contains a control circuit (19) configured to control the high-voltage circuit. The auxiliary casing (10b) is connected to the main casing (10a) by a cable (23). The main casing (10a) and the auxiliary casing (10b) are accommodated in a front compartment (2) of a vehicle together with a motor case (3) that accommodates the motor. The main casing (10a) is fixedly mounted on the motor case (3). The auxiliary casing (10b) is arranged so as to be adjacent to the main casing (10a) and is fixed to a body of the vehicle.

Abstract: A power conversion device includes a laminated unit, a reactor, a shield, and coolant passages. In the laminated unit, flat-plate semiconductor modules housing semiconductor elements and flat-plate cooling plates are laminated. The shield is interposed between the reactor and electronic components. The coolant passages supply coolant to or discharge coolant from the laminated unit. The coolant passages pass through an interior of the shield.
