In the future, robots will be able to charge our cars in restricted areas. Take Volkswagens’ Mobile Charging Robot for instance: it operates autonomously and independently steers the vehicle to be charged. It takes care of opening the charging socket flap, connecting the plug, and removing it.
This robot can also charge several vehicles at the same time:
the mobile robot moves a trailer, essentially a mobile energy storage unit, to the vehicle, connects it up and then uses this energy storage unit to charge the battery of the electric vehicle. The energy storage unit stays with the vehicle during the charging process. In the meantime, the robot charges other electric vehicles. Once the charging service has ended, the robot independently collects the mobile energy storage unit and takes it back to the central charging station.
