8 Service and maintenance
8.1 General inspection of the station
The charging infrastructure operator should perform regular inspections of the charging
stations (preventive maintenance). Public charging stations are often exposed to harsh climate
conditions and mechanical damage. Critical damage of the casing or other components of the
charging station can affect user safety.
The duty of the maintenance service is to:
• examine every socket for potential damage. Access to the sockets must be enabled at all
times and any foreign objects that might be lodged in must be removed as soon as
possible,
• examine the casing of the charging station for potential damage. The internal
components of the charging station can be examined by unlocking and opening the
service doors of the station. The maintenance staff should look for mechanical damage
of individual components and examine the interior for potential presence of water or
moisture. The equipment installed in the upper part of the station (LCD, RFID) is the
most delicate and should be examined thoroughly,
• examine the functioning of ground protection of each socket, by using the »test« button
on the protection,
• examine the functioning of the charging station:
- Plug in the cable into socket 1,
- Perform RFID identification to start the charging. In the case of IEC 62196-2 Type
2 socket, the plug should be locked into the socket.
- To conduct an optimal test, some energy consumption should be induced.
Amount of energy consumed is shown on the LCD display,
- Log off with the RFID card,
- Charging should stop with the plug unlocked from the socket (when testing the
IEC 62196-2 Type 2 socket).
- Repeat the procedure for socket 2.
