Siemens has developed an autonomous fast charger for a wide range of electric vehicles.
The Siemens Autonomous Charging System enables the fully automated charging of electric vehicles from sports cars to long-haul trucks.
The prototype was shown for the first time at the IAA Mobility show in Munich and has a charging capacity of up to 300kW and will be increased to over 1 MW in a further development stage. An automated system is necessary at the 1MW power level for larger trucks with a higher battery capacity as the charging cables are too heavy for people to plug in by themselves. Siemens sees other applications for the new charging system, particularly for disabled people who cannot handle the charging cables.

Other groups at Volkswagen, Tesla and at the University of Graz in Austria have been working on autonomous charging systems. ABB is also working on charging systems for heavy duty trucks in mining applications.
The Siemens system uses cameras to detect the position of the charger on the vehicle, adjusting with horizontal and vertical linear motors, but this also needs remote opening of the charger cover. It is also designed for heavy duty environments such as truck depots.
To test the Siemens Autonomous Charging System under real life conditions and complete its development, Siemens is working with Einride to supply power to an autonomous truck.
