To provide a system of low cost and low loss capable of the supply of electric power according to characteristics of each of a plurality of motors from a single battery. A power supply system for a vehicle of the present invention includes: a high-voltage battery; a first inverter which connects with the high-voltage battery; a motor described later which connects with the first inverter; a high-voltage DCDC converter which is connected to the high-voltage battery and steps down the voltage of the high-voltage battery; a second inverter which connects with the high-voltage battery; and a motor described later which connects with the second inverter.

Power supply system for vehicle

A connector structure installed in the electric vehicle includes a plurality of connectors, an inter-connector conductive member configured to electrically connect the plurality of connectors, and a connector casing configured to house the inter-connector conductive member. A cover is attached to the unused connector of the plurality of connectors.

Connector structure and electric vehicle

A power reception apparatus includes a secondary coil which receives power in a non-contact state from a power transmission apparatus having a primary coil, while being disposed opposite to the power transmission apparatus, a housing which accommodates the secondary coil to form a space between the secondary coil and the housing, an insulating fluid filled in the space, a measurement unit which measures efficiency of a non-contact power transmission between the primary coil and the secondary coil, and a detection unit which detects damage made to the housing based on a change in the efficiency during the non-contact power transmission.

Power reception apparatus, vehicle, and detection method

A power supply device includes: an electric storage unit; a connection unit connected to the electric storage unit; a housing which houses the electric storage unit; a power receiving unit which receives AC power in a noncontact manner; a rectifier which converts the AC power into DC power and outputs the DC power; an AC lead wire which connects the power receiving unit and the rectifier; and a DC lead wire which connects the rectifier and the connection unit. The power receiving unit is connected to the housing via a heat conduction unit, an opening is provided on a surface facing the power receiving unit in the housing, any one of the AC lead wire, the DC lead wire and the rectifier is disposed to pass through the opening, and the housing has a heat capacity larger than that of the power receiving unit.

Power supply device and transport apparatus

A vehicle includes a cover, a front protector, and a rear protector. The cover has a cover lowest portion projecting from the bottom of the vehicle body toward an outside of the vehicle by a first distance. The front protector is provided on a front side of the cover in a front-rear direction. The front protector has a front protector lowest portion projecting from the bottom of the vehicle body toward the outside of the vehicle a second distance longer than the first distance. The rear protector is provided on a rear side of the cover in the front-rear direction. The cover is provided between the front protector and the rear protector in the front-rear direction. The rear protector has a rear protector lowest portion projecting from the bottom toward the outside of the vehicle by a third distance longer than the first distance.

Vehicle and protector structure

The power reception apparatus includes a secondary coil which receives power in a non-contact state from a power transmission apparatus having a primary coil, while facing the power transmission apparatus, a housing which houses the secondary coil to form a space between the secondary coil and the housing, a fluid filled in the space, a sensor which is disposed in the space and detects a change in the a liquid level height of the fluid, and a detection unit which detects a breakage of the housing, based on a the change in the liquid level height detected by the sensor.

A non-contact charging system includes a charging device and a mobile object. The charging device includes a transmitter. The transmitter is provided at a predetermined position in a charging area and has a power transmission surface to transmit electric power using a magnetic field. The mobile object includes a receiver. The receiver is provided in the mobile object and has a power reception surface to receive the electric power from the charging device through the transmitter. The power transmission surface faces the power reception surface when the mobile object enters the charging area. At least one of the power transmission surface and the power reception surface is tilted relative to ground in the charging area in a longitudinal direction of the mobile object.

Non-contact charging system

A power controller for a vehicle includes a power converter module, a three-phase terminal, and a three-phase terminal base. The three-phase terminal includes a first flat portion, a second flat portion, and a curved portion. The first flat portion is connected to a contact surface of a three-phase output terminal to be in contact with the contact surface. The second flat portion is connected to a fixed surface of the three-phase terminal base to be in contact with the fixed surface. The three-phase terminal has a shape such that a predetermined gap is provided between the first flat portion and the contact surface of the three-phase output terminal when the first flat portion is released from the contact surface of the three-phase output terminal while the second flat portion is being in contact with the fixed surface of the three-phase terminal base.

Power controller

A dynamic foil gas bearing includes a foil group comprising a corrugated-sheet-like bump foil, a flat-sheet-like middle foil, and a flat-sheet-like top foil which are arranged successively toward the center axis of a bearing case. The top foil includes a second linkage surface joined to a second fixed surface fixed to an inner circumferential surface of the bearing case and also joined to a second rotatable shaft holding surface. The second linkage surface is provided by a curved portion of the top foil which is convex toward the center axis of the bearing case. The middle foil includes a first linkage surface joined to a first fixed surface fixed to the inner circumferential surface of the bearing case and also joined to a first rotatable shaft holding surface. The first linkage surface is provided by a bent straight portion of the middle foil.
