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 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

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 capacitor unit includes a casing, a heat sink, a heat radiation sheet, and a notch. The casing accommodates the capacitors. The casing includes a positive electrode terminal block and a negative electrode terminal block. The heat sink is provided on the casing in a stacking direction. The heat radiation sheet is made of insulation material and is sandwiched in the stacking direction between the casing and the heat sink to cover the positive electrode terminal block and the negative electrode terminal block. The notch is provided in at least one of the casing and the heat radiation sheet between the negative electrode terminal block and the positive electrode terminal block. The notch passes through the at least one of the casing and the heat radiation sheet along a plain substantially perpendicular to the stacking direction to separate the negative electrode terminal block and the positive electrode terminal block.

Capacitor unit and capacitor casing structure

A capacitor arrangement structure includes a casing, a housing, and a heat sink. The casing accommodates a capacitor. The casing includes a casing bottom. The housing includes a bottom wall. The housing has a height from the bottom wall which includes an inner surface and an outer surface opposite to the inner surface in a height direction. The casing is mounted on the inner surface so that the casing bottom opposes a mounting surface in the inner surface. The heat sink includes a heat sink top. The heat sink is provided on the outer surface of the bottom wall not to overlap the casing viewed along the height direction. The heat sink top opposes the outer surface. A distance between the casing bottom and the mounting surface in the height direction is smaller than a distance between the heat sink top and the mounting surface in the height direction.
