10.2.3 Intelligent charging control - load management
In intelligent charging control, the total current taken from the charging station and from the
other domestic equipment via the main infeed line of the building is measured by an energy
meter (MID) integrated in the main power line.
The MID is connected to the charging station to be controlled with a twin-core cable.
Communication is according to the Modbus protocol.
The house connection value (in amps) is set using the DIP switch in the charging station. In
accordance with the threshold value set by the user, the charging station adapts its output
charging current dynamically to suit the measurement of the main power line. The charging
station regulates the charging power of the electric vehicle according to the load on the main
infeed to the house.
If the total current taken up by the charging station and the house equipment reaches the
threshold value set on the DIP switch, the charging power on the charging station is reduced.
Illustration 16: DIP switches no. 4, 5, 6
The DIP switches no. 4, 5, and 6 correspond to the binary figures of the maximum current
value, as shown in the following . The intelligent control system is deactivated if switches 4, 5,
and 6 are in the OFF position.
