Abstract:
1. A method for controlling fluid charge, the method comprising: transmitting a target charging profile stored in a movable object from the movable object to a supply facility, the target charging profile being set according to a characteristic of the tank to specify a target charging pressure of fluid in each elapsed time point from a beginning of fluid charge when a tank of the movable object is charged with fluid from the supply facility; receiving the target transmitted charging profile; controlling charging pressure of fluid, in each elapsed time point, at the target charging pressure specified by the received charging profile, when fluid is charged to a specific movable object, which corresponds to the target charging profile; detecting an actual in-tank temperature value and an actual in-tank pressure value of the tank during the charging of the fluid from the supply facility to the movable object; transmitting the detected actual in-tank temperature value and the detected actual in-tank pressure value to the supply facility, determining whether or not the actual in-tank pressure value transmitted from the movable object is normal with respect to the target charging profile during the charging of the fluid to the movable object, wherein when it is determined that the actual in-tank pressure value is normal with respect to the target charging profile, the charging pressure control unit continues to charge the fluid to the movable object in accordance with the target charging profile, and when it is determined that the actual in-tank pressure value is abnormal with respect to the target charging profile, the charging pressure control unit charges the fluid to the movable object in accordance with the actual in-tank pressure value instead of the target charging profile; determining, upon completion of the charging of the fluid to the movable object, that the charging of the fluid to the movable object has been completed not in accordance with the charging profile, when it is determined that the actual in-tank pressure value is abnormal with respect to the target charging profile; updating contents of the target charging profile based on the actual in-tank pressure value in the charging of the fluid to the movable object, when it is determined that the charging of fluid to the movable object has been completed not in accordance with the charging profile; transmitting the calculated updated contents of the target charging profile to the movable object; and updating the stored target charging profile in the movable object with the updated contents of the target charging profile.
