What if a Robot Charged Your Apple Car For You? - The Mac Observer

A patent granted to Apple today references a robot that could autonomously carry a power cord to an electric car (via AppleInsider). The patent, dubbed "Charging System" is about a "mobile charging device may be used to move a battery or a power cord to a target device." The device could attach a power cord to the vehicle, couple a connector, or use a wireless power transfer element. Sensors embedded in the vehicle would help the robot find the power port. It may be desirable to transfer power between a source of power and equipment that requires power.
