Digital signed meter values
The transmission of digitally signed readings is a basic requirement that a charging station must support in order to meet the requirements of calibration law in Germany. If the charging device supports this functionality, the transactions at the station can be verified at any time using the process described below. The station can thus also be operated semi-publicly or publicly via eCarUp.
