ShiftGuard
USER MANUAL
BASIC PURPOSE
The ShiftGuard PLC (Power Line Communication)
modules are communication components for
electric vehicle charging infrastructure. These PLC
modems can also be used for transmission of binary
signals in a wide range of applications. For example,
they are used instead of conventional power cables
to transmit information on the current tariffs of
electricity meters. When installed in the VoltDrive
charging infrastructure system, the ShiftGuard PLC
modems are used to transmit information from the
HomeGuard residual capacity meter of the electrical
connection to the electric vehicle charging station.
It enables the PortGuard charging control unit to
set the charging current exactly according to the
current available at the point of supply (at the
distribution meter). The communication between
the HomeGuard Residual Capacity Meter and the
PortGuard charging control unit can also be done
by means of RS485 twisted pair bus, however,
such a cable is usually not installed between the
input of the power supply point and the charging
station. In case the installation uses the ShiftGuard PLC modems, the charging station can be placed anywhere
after the distribution meter. When used in the tariff control system, a pair of the ShiftGuard PLC modems replaces
the communication cable carrying information on the current tariff. PLC communication enables the distribution of
information on the current tariff to any home appliance in a flat or a house.
