A vehicle is equipped with a hydrogen tank that stores hydrogen, a fuel cell that generates electricity from the hydrogen in the hydrogen tank, a filling devicethat fills a fuel cell vehicle with the hydrogen stored in the hydrogen tank, and a charger with which electricity generated by the fuel cell is charged to an electric vehicle. Using the vehicle, hydrogen and electricity are delivered to the home of a user.

Vehicle, delivery system, server, and program for delivery system

A power supply device includes a moving unit that moves a power supply fitting body in an insertion-extraction direction, an up-down direction, and a lateral direction that is orthogonal to the insertion-extraction direction and the up-down direction, and a controller that controls the movement of the power supply fitting body by the moving unit. A position detection device moves in linkage with the movement of the power supply fitting body by the moving unit. A power reception fitting body includes first structures extending along the lateral direction and second structures related to a central position of the power reception fitting body in the lateral direction. The first structure and the second structure are formed protruding to one side of the up-down direction with respect to a ceiling surface. The distances between the second structures and the first structures in the insertion-extraction direction are set in advance.

Vehicle charging system

A module driver or a master obtains the load IDs of the respective first loads connected to the downstream side of the module driver, recognizes the classification of areas, such as door, roof and floor areas, or a module according to the obtained load IDs, and allocates an appropriate driver ID to the module driver in each area. Each first load has a load ID. The load IDs are allocated to the respective second loads on the downstream side of the module driver on the basis of the allocated driver ID. The area or the module is recognized on the basis of the combination of the load IDs of the plurality of first loads, whereby malfunctions caused by erroneous assembling of the first loads are suppressed.

On-vehicle controller

In a vehicular power supply system according to an embodiment, passage current of a power MOSFET of an IPD of a sub power distribution box monitored by a sub controller of the sub power distribution box is transmitted from the sub controller to a main controller of a main power distribution box. When energy storage amount of a load-based path calculated by integrating the passage current received by the main controller exceeds a predetermined value which is a overcurrent state, the main controller determines that the load-based path is in the overcurrent, and notifies the fact from the main controller to the sub controller. The sub controller switches the power MOSFET of the IPD of the load-based path set to the overcurrent by the notification to a non-conduction state to interrupt the energization of the load-based path.

An on-vehicle circuit unit includes a first conductor that is a power supply line, a second conductor that is a ground line a dielectric that is disposed between the first conductor and the second conductor.

On-vehicle circuit unit

A power transmission system is provided. In the power transmission system, a plurality of power supply voltages are switched alternately and periodically, and is sent from an upstream module unit toward a downstream control unit as one system of output voltage. In the downstream control unit, a plurality of voltages from the inputted voltage is separated and supplied to loads, and the voltage is monitored so as to determine switching timing. Further, the downstream control unit is equipped with capacitors for each system of voltages, and thereby the voltages are maintained even during a time period when no power is supplied from the upstream module unit. A low voltage required by a CPU of the downstream control unit is generated by a voltage regulator of the downstream control unit. The power loss that is caused in generating power to be consumed by low-voltage loads can be reduced.
