Service plug configuration

This application further references U.S. patent application "Service Coupling" to Mulvenna et al., and U.S. patent application "Connectivity Device" to Mulvenna et al., filed concurrently with this application. This invention relates to a fluid and electrical coupling for coupling a vehicle to a service port such that a fluid and electricity is transferable therebetween. The coupling includes a plug having a pair of opposed major surfaces, a fluid exchange interface on one of the major surfaces, and an electricity exchange interface on the other major surface. The coupling also includes a receptacle having an opening for receiving the plug, a fluid exchange interface facing the plug fluid exchange interface when the plug is coupled to the receptacle, and an electricity exchange interface facing the plug electricity exchange interface when the plug is coupled to the receptacle.
