On the road, HARRI is pretty independent when it comes to conductive charging, i.e. charging via a cable connection and a charging device. The electronics engineers have equipped the vehicle with the necessary charging technology, which meets the international standard IEC 61851. Thus, HARRI is capable of non-proprietary communication with all publicly accessible alternating current (AC) and high-speed charging stations.
Cloud to cloud communication
To put it precisely, the data exchange for the charging process takes place between HARRI’s cloud and the charging station’s cloud. The charging process begins as soon as it is clear what the available voltage of the vehicle battery is and how much energy it requires. This can also be initiated via the charging app. The vehicle’s onboard charger transforms the alternating current from the AC charging stations into the direct current (DC) that the battery requires and ensures an optimal and battery-saving charging procedure. To accomplish this, the charging device communicates with the battery management system.
Charging is becoming ever more intelligent
Right now, the plug for conductive charging must still be manually plugged into the device. However, our experts are already hard at work investigating and evaluating charging systems of the future, such as inductive charging, automated charging via a robotic arm and innovative plug connection options. Moreover, they are checking to see which communications system between the charging post and the vehicle is most appropriate. We will be addressing this project in the near future. Then, HARRI will switch from its current relatively simple communication to bidirectional communication. That is smart charging according to the ISO15118 international standard.
