8.3 Installing new versions of charging station's firmware
New firmware versions are installed through the application in the charging infrastructure
Control centre. The system administrator manages new firmware versions and their distribution
to individual charging stations.
New firmware versions cannot be installed while charging is in progress. Installing of new
firmware versions is performed in a few steps:
1. Application in the Control centre notifies the charging station that a new firmware
version is ready to be installed,
2. When it becomes available, the station begins downloading the new firmware version,
3. After the firmware is successfully downloaded, the install process is started,
4. After the firmware is installed, the station is automatically restarted.
8.4 Communication with the control centre
For its normal operation, the charging station requires an active connection with the Control
centre. The communication is required mainly to perform central user identification, transfer
billing data and charging detail records, and to exercise remote control over the charging
process.
If there is no communication connection with the Control centre, user identification is not
possible and therefore no charging can be started on stations that require identification of EV
users.
The charging station communicates even when it is »Available«. It cyclically sends its general
status to the Control centre for means of communication control.
If it is diagnosed that the charging station does not have a reliable communication connection
with the Control centre, alternative communication solutions need to be considered (new GPRS
service provider, upgrade of the antenna, different communication channel – ADSL, WAN
network).
