Conclusion
The transmission capacity of
BB PLC devices have more
advantages than the NB PLC
devices.
Equipment location, different
load current, chargers based on
different technologies will result
in the different channel
background noise. The
interference to the NB and BB
PLC is different.
The background noise of
power cable is higher
than the control cable.
Background noise of
Load side is higher
than charging pile side.
The noise generated by
different
charger is different.
Based on control cable
channel, both BB and
NB PLC have very good
communication
performance.
Based on power cable
channel, in the case of
heavy load, BB PLC has
better communication
stability than NB PLC.
Still the NB PLC can
afford the
communication between
EV and Charging
facilities.
Test Analysis and Conclusion
Thank you!
