The mobile charging complex consists of a pair of elements: directly a robotic device and a mobile installation with batteries. The principle of operation is as follows: the driver leaves the car in the parking lot and sends a call to the robot through an app on the smartphone. The device itself finds the charging connector, removes its cover, and docks the cable with the power source. After that, it repeats the operation with other electric vehicles that need charging.

The portable battery with a capacity of 25 kWh is equipped with a fast charging module of 50 kilowatts. The robot, in turn, is equipped with a set of sensors and sensors that allow it to navigate in space and bypass parked cars.

Earlier, Volkswagen announced an original mobile charging station, which in the future will be used to replenish the energy of electric vehicles. Such equipment will be placed in any locations — at parking lots in cities, near business centers, or at large events.
