摘要:
A traffic system includes: a vehicle having a power-receiving section on an outer surface thereof; and a ground facility having a power-supply section for supplying the power-receiving section with power by coming in contact with the power-receiving section. The power-supply section has a spring for applying a biasing force to a power-supply shoe in the power-supply section toward the power-receiving section. The power-receiving section has a flat surface that extends along the outer surface of the vehicle, and tapered surfaces that are connected to the flat surface in the forward and backward moving directions of the vehicle and guide the power-supply shoe to the flat surface against the biasing force to bring the power-supply shoe into contact with the flat surface when the vehicle moves backward and forward.

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.

A charge control device determines a current value acquired by dividing a current amount that should be charged in a secondary battery in a vehicle at a charging location by an allowable charging time at the charging location on the basis of a charging amount as a physical quantity associated with the charging state of the secondary battery. When the vehicle arrives at the charging location, the charge control device allows a charging device provided at the charging location to charge the secondary battery with the current having the determined current value for the allowable charging time.
