DELIVERY VEHICLE SYSTEM AND CHARGE METHOD FOR DELIVERY VEHICLE

In a system of charging a transport vehicle electric storage device immediately, transport vehicles under control of a ground controller and travelling by an electric storage device as a power source travel along a predetermined travelling route. Chargers respectively having a rectifier rectifying alternating current into direct current, an electric storage device in the charger charged by the rectifier, and a charging coupler charging the electric storage device in the transport vehicle are disposed in locations along the travelling route. The vehicle includes means for reporting a position and residual capacity of the electric storage device to the ground controller, and the ground controller includes a charging management unit selecting a transport vehicle in accordance with the residual capacities of the electric storage devices in the transport vehicles and positions of the transport vehicles, selecting and specifying a charging coupler for the selected vehicle, and controlling so that the selected transport vehicle stops and charges at the specified charging coupler.
