A supply facility is configured to charge fluid to a tank of a movable object. A charging profile storage unit is provided to the movable object to store a charging profile specifying a charging pressure of fluid in each elapsed time point from a beginning of fluid charge. A charging profile transmission unit is provided to the movable object to transmit the charging profile to the supply facility. A charging profile reception unit is provided to the supply facility to receive a charging profile transmitted from the charging profile transmission unit. A charging pressure control unit is provided to the supply facility to control charging pressure of fluid according to the charging profile when fluid is charged to a movable object, which corresponds to the charging profile.

Fluid charging system, movable object, supply facility, and method for controlling fluid charge

A supply facility supplies fluid to a movable object through a feed pipe connected with a connection port of the movable object. A feed connector of the feed pipe is rotatable around its axis when the feed pipe is connected with the connection port. At least one of the feed pipe of the supply facility and the movable object has multiple infrared communication elements. When the feed connector of the feed pipe is connected with the connection port of the movable object, at least one of the infrared communication elements is communicable with an infrared communication device on the other side via an infrared communication, regardless of the rotation phase.

In a condition monitor system for controlling a power supply in a vehicle, a charge/discharge circuit has a capacitor which is discharged in response to each of speed pulses of a speed sensor and periodic pulses of a microcomputer. When none of the pulses are generated due to abnormality, the capacitor is continuously charged without being discharged. When the charge voltage of the capacitor reaches a switching voltage, a relay is turned off to shut off the power supply to various parts in the vehicle. The charge/discharge circuit is commonly used to check generation of the speed pulses and the periodic pulses by setting the switching voltage in accordance with a possible maximum time interval of the speed pulses.

An engine starting assist system includes an auxiliary ECU having a voltage booster, an engine ECU, a starter relay, and a starter that allows the engine to be started when a current flows through the starter relay. The auxiliary ECU and the engine ECU are powered by a battery and supply currents to the starter relay. When the engine ECU resets the supply of the current to the starter relay because of a voltage drop of the battery during starting of the engine, the auxiliary ECU increases the voltage supplied from the battery using the booster, thereby supplying the current to the starter relay.

Engine starting assist system

A load operating means controls electricity supplied from a power source to a starter in an auxiliary system for starting an engine. An engine control means and an auxiliary electricity supply means turn the load operating means ON for supplying electricity from the power source to the starter in accordance with electricity supply from a power supply device when the engine is started. When voltage of the power supply device becomes less than a reset level, the engine control means resets electricity supply to the load operating means. When the engine control means starts the engine, the auxiliary electricity supply means supplies electricity to the load operating means at a timing simultaneously with or in advance of supplying electricity by the engine control means. When the engine control means resets the electricity supply, the auxiliary electricity supply means supplies electricity instead of the engine control means.
