  • Publication number: 20230191951
    Abstract: This positioning configuration design device includes a positioning configuration setting unit that excludes facilities which are likely to be able to be excluded from facilities respectively positioned at a plurality of locations and sets a positioning configuration of the facilities; a feasibility confirmation unit that judges whether predetermined conditions are feasible or not in the set positioning configuration of the facilities; an exclusion candidate list updating unit that registers, in an exclusion candidate list, information of the facilities excluded in the positioning configuration in which the conditions are feasible, a non-excludable list updating unit that registers, in a non-excludable list, information of the facilities excluded in the positioning configuration in which the conditions are not feasible; and a control unit that repeatedly executes confirmation processing including setting of the positioning configuration and judgment of feasibility of the conditions while incrementing the numb

  • Patent number: 10155450
    Abstract: This charging device is provided with a charger, a resistor, a ground-side switch, and a determination device. The charger charges a secondary battery that is provided to a vehicle. The resistor is connected in parallel with the charger. The ground-side switch connects the charger and the resistor in an openable/closable manner. The determination device acquires information indicating that the ground-side switch is closed and information indicating that a vehicle-side switch that connects the secondary battery and the charger in an openable/closable manner is open and subsequently determines that the vehicle-side switch is short-circuited when a physical quantity that relates to the electricity of the resistor does not decrease.

  • Patent number: 10150379
    Abstract: A charging control device includes a power reception unit, a charging instruction output unit, and a travel instruction output unit. The power reception unit receives power from a power supply device when the power reception unit is present in a power supply area where the power from the power supply device can be supplied. The charging instruction output unit outputs a charging instruction relating to charging of a secondary battery using the power received by the power reception unit. The travel instruction output unit outputs a travel instruction relating to traveling of a vehicle provided with the charging control device. The secondary battery and a travel motor are electrically insulated from each other when the charging instruction output unit outputs a charging start instruction as the charging instruction for the secondary battery, and are electrically connected to each other when the travel instruction output unit outputs a travel start instruction for the vehicle.

  • Patent number: 9738173
    Abstract: A charging and discharging control device includes a pantograph point voltage detection unit configured to detect a pantograph point voltage of a vehicle, a charging and discharging control unit configured to charge a power storage device provided in a vehicle when the pantograph point voltage is greater than or equal to a charging voltage threshold value and discharge the power storage device when the pantograph point voltage is less than a discharging voltage threshold value, a load determination unit configured to determine whether an absolute value of load power for the vehicle is less than a load power threshold value, and a charging and discharging control change unit configured to reduce any one of more of the charging voltage threshold value, the discharging voltage threshold value, and charging/discharging impedance when the absolute value of the load power is less than the load power threshold value.

  • Patent number: 8508186
    Abstract: The present invention provides a charging system for a transportation system without a contact wire having a configuration in which a power storage device of a vehicle is charged by a charging device provided on the ground when the vehicle equipped with the power storage device stops at a station on a track. In the present invention, the track includes a first track and a second track, the station includes a station controller which detects stopping of the vehicle, the charging device includes a first power line for supplying power to a vehicle on the first track and a second power line for supplying power to a vehicle on the second track, the first power line and the second power line each include switching means for controlling flow of the power supplied from the charging device, and the station controller controls the switching means, thereby causing the charging device to charge any of the vehicle on the first track and the vehicle on the second track.
