Volkswagen Unveils Mobile Charging Robots For Electric Vehicles
Volkswagen unveiled the future of electric vehicle charging with Volkswagen Group Components’ mobile charging robot.
This robot drives itself to the vehicle that needs charging and communicates with it. From opening the charging socket flap to connecting the plug to decoupling – the entire charging process occurs without any human interaction.
The charging robot brings a trailer in the form of a mobile energy storage device to the vehicle and connects them and then uses this energy storage device to charge the battery of the electric vehicle. The mobile energy storage device stays with the vehicle during the whole charging process. The robot, in the meantime, charges other electric vehicles.
Once the charging service is complete, the robot collects the energy storage device and brings it back to the charging station.
“The mobile charging robot will spark a revolution when it comes to charging in different parking facilities, such as multi-storey car parks, parking spaces and underground car parks because we bring the charging infrastructure to the car and not the other way around. With this, we are making almost every car park electric, without any complex individual infrastructural measures,” said Mark Möller, head of development at Volkswagen Group Components.
“It’s a visionary prototype, which can be made into reality quite quickly, if the general conditions are right”, Möller continued. Volkswagen Group Components is researching different approaches to the assembly of charging infrastructure and has already developed several successful products. The flexible quick charging station and DC wall boxes are already part of a future charging family. Customer-oriented, intelligent and flexible approaches to charging are at the centre of the research. Other innovative products such as the charging robot are currently being developed.
The robot, which can drive autonomously, is fitted with cameras, laser scanners and ultrasonic sensors. The combination of these systems not only allows the robot to carry out the charging process completely autonomously but also to move around freely in the parking area, to recognize possible obstacles and to react to these. Depending on the size of the parking area or the underground car park, several charging robots can be employed simultaneously so that several vehicles can be attended to.
The mobile charging robot can be put to use in various ways. It isn’t just a robot arm that connects a car to a fixed charging station. Instead, drivers have the choice to park in any available space, independent of whether a charging station is free or not. The robot brings the charging station in the form of a mobile energy storage device directly to the vehicle. For operators of different parking facilities this is a quick and easy solution to electrify every parking space. “This approach has an enormous economic potential”, said Möller. “The constructional work as well as the costs for the assembly of the charging infrastructure can be reduced considerably through the use of the robots.”
The compact design of the charging robot is suited for use in restricted parking areas without charging infrastructures, such as underground car parks. Möller continued “Even the well-known problem of a charging station being blocked by another vehicle will no longer exist with our concept. You simply choose any parking space as usual. You can leave the rest to our electronic helper.”
A possible date for the market launch of the charging robot has not been set yet.
