Charging e-cars with robots: automatic charging of electric cars?


For people with limited mobility, charging robots could one day be an incentive to buy an electric car.
And this is how the procedure works: When activated, the charging socket cover on the car and the column cover open. Then, with the help of a tiny camera, the charging arm moves to the charging port on the vehicle. Charge status can be monitored via the FordPass app. After charging, the arm retracts again.
The charging robot could be used in disabled parking spaces, but also in regular parking spaces or in the area of ​​private households. The fast and efficient charging of company fleets is also conceivable – or in the distant future the fully automatic charging process for an autonomous electric car.
Conti loading robot loads via the underbody
But other manufacturers and suppliers are already developing mobile charging solutions. Continental – more precisely the service provider Continental Engineering Services (CES) – is developing a charging robot with the startup Volterio that is intended to make charging with electricity much more convenient.

Conti’s charging solution consists of one unit on the underbody of the vehicle and one on the garage or parking lot floor.
The system consists of two components: one unit on the underbody of the vehicle and one on the garage or parking lot floor. As soon as the car is parked, both connect via a smart automatic using ultra broadband, a radio-based communication technology. The car does not have to be parked accurately, the charging robot corrects deviations of up to 30 centimeters from the ideal position.

The use of the Continental charging robot is initially in private households with a suitable perfomance of 22 kW alternating current planned. In a second step, a fast charging solution that can be lowered into the ground for car parks, gas stations or operating areas with a charging capacity of more than 50 kW direct current. Commercial vehicle fleets should also be able to benefit at some point. However, the first series production of the system is initially planned for 2024 in Germany.
VW charging robot with battery wagons
At the beginning of 2020, Volkswagen presented a charging concept in which a charging robot brings a mobile energy storage device to the electric vehicle completely autonomously. Opening the charging flap, connecting the plug and finally decoupling – the entire charging process takes place without human intervention.
What is happening in a parking lot, in a multi-storey car park or in an underground car park is controlled via app or Car-to-X communication. If a mobile memory is connected, the robot can take care of the next one if necessary.

When fully charged, the battery wagons of the VW charging robot have an energy content of approx. 25 kWh each.
How DC fast charging works with up to 50 kW
Charging robot from Austria with lidar
A similarly mobile charging robot was presented in Austria in the summer of 2021 – developed by Graz University of Technology, the charging solution specialist Alveri and the company Arti Robots. Of the prototype consists of two units: a mobile platform that moves autonomously in space with lidar sensors at up to 20 km/h, and a robotic arm that independently connects the charging plug to the electric vehicle. After the (quick) charging process, the robot unplugs itself again and moves away from the vehicle.

This charging robot from Austria is to be used in multi-storey car parks or on the outskirts of major events.
The motivation behind the efforts is to help e-mobility to get more space. The mobile charging robot is intended for public use in multi-storey car parks, on Park&Ride areas or larger commercial parking areas. However, there is still some development work to be done: the prototype was still attached to the power cable during the presentation, the software ran on a separate PC. The designers also saw opportunities for optimizing the weight and costs of the robotic arm.
How does Tesla’s charging queue work?
But although an automated charging option was considered indispensable at Tesla at the time and company guru Elon Musk publicly announced the charging line again five years later, there is still no result of the efforts that is ready for series production.
