Electric Vehicle Automatic Recharging Robot


Samsung C-Lab developed ‘EVAR,’ an Electric Vehicle Automatic Recharging Robot, for the First Time in the Industry Circle.

[INQ. NO. 1810M09] An in-house venture of Samsung Electronics has developed an electric vehicle automatic recharging robot for the first time in the industry. With a robot, you need not touch the high-voltage recharging cable to charge the electric vehicle. There is no need to have a dedicated parking space for installation of fixed facilities. As it is made of waste batteries of electric vehicles left throughout the country, reuse value is also secured. It is notable how Samsung Electronics will commercialize this robot.
According to the industry, a C-lab engaging in the in-house venture development program of Samsung Electronics has recently developed ‘EVAR,’ an electric vehicle automatic recharging robot. EVAR finds by itself any electric vehicle that needs to be recharged, recharges it without human help and then returns to its original location. Its structure is similar to that of a home robot vacuum cleaner.
There existed similar types of recharger including the fixed-type recharging robot jointly developed by Volkswagen and Kuka and the mobile recharger developed by FreeWire of the USA. However, EVAR is the world’s first robot that finds and recharges the vehicle by itself without human help using the autonomous driving function.
In case of EVAR, all that the first driver has to do is to connect the exclusive adaptor to the vehicle charging port and then mount it on the front license plate. All the work is done just by giving a recharging order with a smartphone (NFC communication).
The robot that received the command searches the corresponding vehicle by recognizing the QR code at its own position, recognizes the license plate of the vehicle, and automatically recharges the electric vehicle. This robot is designed to perfectly match the vehicle charging connector and the robot charging port by applying the three-axis (XYZ) precision control algorithm at this time.
The adaptor mounted on the vehicle license plate plays a role of docking station connecting the vehicle with the robot.
EVAR moves at a maximum speed of 2 km/h. LIDAR and ultrasonic sensors are used to detect obstacles and movement routes. This robot is designed to stop immediately in the event of collision as the bumper located at its bottom is equipped with a push switch sensor.
After recharging is completed, the robot automatically returns to the separate recharging facility for recharging the battery built in the robot. The EVAR recharging output released at this time was designed in a slow speed (7 kW), but it is also possible to manufacture a medium-speed recharging robot of 20 to 30kW level. As it is manufactured to the standardized battery pack of the existing electric vehicle, the robot can be commercialized based on the waste batteries without any complicated application work.
