Resuming charging after a power failure
The web interface can be used to set how the charging station should be-
have after a power failure with a vehicle (still) plugged in. The setting is lo-
cated in the following menu in the web interface:
Configuration ► Charg-
ing Parameters ► Resume After Power Cut
The following settings are possible:
●
True
: After a power failure, the charging session is continued again with
a "predefined token." This kind of charging session cannot be assigned
to any customer.
●
False
: After a power failure, if a vehicle is plugged in, a new charging
session does not start automatically. Renewed authorization by the user
is necessary.
Information

Verification of measurement data using the transparency
and display software
Using the
transparency and display software
, users can check whether the
measurement data comes from a certain charging station and whether its in-
tegrity/authenticity has been maintained.
During production, the charging station gets a key pair consisting of one pri-
vate key and one public key. The private key is only known to the charging
station. The public key is openly available and indicated on the type plate of
the charging station in the form of a QR code.
For each charging process, the charging station creates a measurement
data record in the measurement capsule. The measurement capsule signs
this measurement data record with the aid of the private key.
The charge point operator then uses the signed measurement data record to
create the bill. Both the signed measurement data and the public key, in a
format that is compatible with the transparency and display software, must
be provided on the bill or in a customer portal.
