Volkswagen Group offers a first glimpse of its mobile charging robot. This is one of the visionary charging concepts that Volkswagen hopes will expand the charging infrastructure over the next few years. Its task: fully autonomous charging of vehicles in restricted parking areas, like underground car parks.
“A ubiquitous charging infrastructure is and remains a key factor in the success of electric mobility. Our charging robot is just one of several approaches, but is undoubtedly one of the most visionary,” explains Thomas Schmall, Volkswagen Group Components’ CEO.
Fully autonomous charging
The charging robot – started via an app or Car-to-X communication – operates totally autonomously. It independently steers the vehicle to be charged and communicates with it: from opening the charging socket flap to connecting the plug and decoupling it. The entire charging process takes place without any human involvement whatsoever. To 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.
The move will reassure many drivers who are put off electric cars not only by the expensive RRP, which is often over 30K, but the lack of public charging points when out shopping, on business trips or visiting friends and family.
According to Thomas Schmall, CEO of Volkswagen Group Components: “Setting up an efficient charging infrastructure for the future is a central task that challenges the entire sector. We are developing solutions to help avoid costly stand-alone measures. The mobile charging robot and our flexible quick-charging station are just two of these solutions.” The business unit is currently working on a complete DC charging family.
The flexible quick-charging station will be launched onto the market in early 2021. For several weeks now, the DC wallbox has been trialed at different company’s German production sites. The mobile charging robot has successfully reached prototype status and will now be comprehensively further developed. One of the prerequisites for market maturity is Car-to-X communication to facilitate the autonomous charging process.
The extra benefits of having mobile charging points at things like festivals, outdoor shows or major sporting events are also worth considering as people are happy to park for half a day or so. If mobile EV charging is available and can act as a bolt-on cost, on top of the venue car parking, then so much the better. That also offers an opportunity for insurers and brokers who can underwrite the risks of having mobile EV chargers on-site.
