This is an implementation architecture example for command & control approach including the alignment and pairing procedure using low power excitation (LPE).




PDCC = Primary Device Communication Controller
SDCC = Secondary Device Communication Controller
SECC = Supply Equipment Communication Controller
EVCC = Electric Vehicle Communication Controller
WLN = Wireless Local Network
LPE = Low Power Excitation


(S-1) SECC periodically broadcasts beacons. EV is approaching to the SECC area and EVCC receives the beacon
(S-2) EVCC sends a request to the associated SECC. Receiving the request, SECC will find a vehicle entering the SECC area. At this point, the communication is established.
(S-3) EVCC and SECC exchange each status.
(S-4) EVCC and SECC exchange each compatibility information.
