Service port configurations

The present invention relates generally to the transfer of services, which include electrical energy, fluids and information, between stationary service terminals and mobile devices, such as vehicles. Various service port configurations for the transfer of fluids, gases and electricity between a service terminal and a vehicle are provided. The service port includes a receptacle and a controller. The receptacle includes a clamp and a clamp actuator for actuating the clamp; a service exchange interface in between the clamp; and sensors inside the receptacle and configured to monitor the position of a plug inside the receptacle. The controller is connected to the sensors and the actuator, and monitors the sensors. When a sensor detects that a plug is in position for engagement, the controller instructs the clamp actuator to move the clamp until the plug is clamped with sufficient force to enable a service to be exchanged. The receptacle and the plug are couplable to either the service port or a vehicle and a service terminal, and both are implementable at a multiplicity of locations on a vehicle.
