Charging station for utility vehicle

A charging station for a utility vehicle installed at a boundary of a working area for charging an onboard battery of the vehicle that detects a magnetic field generated during flow of electric current through a boundary wire laid around the working area and connected to an electric power supply and is driven by electric motors to run the working area based on the detected magnetic field, comprising:

• a base plate that is installed at the working area to retain the vehicle and provided with a pair of charging terminals connectable with battery charging terminals of the onboard battery of the vehicle;
• a first wire that is installed at the base plate and is connected to the electric power supply independently of the boundary wire, the first wire having a first loop that loops with a first loop diameter and first projecting segments that project from the first loop toward the base plate symmetrically with respect to an axis connecting a midpoint of the pair of charging terminals and a center of the first loop;
• and
• a second wire that is installed at the base plate and is connected to the electric power supply independently of the boundary wire and the first wire, the second wire having a second loop that loops with a second loop diameter that is larger than the first loop diameter and second projecting segments that project from the second loop toward the base plate symmetrically with the first projecting segments.
