02 BPT SERVICES WITHIN 15118 USING DYNAMIC CONTROL MODE
USE CASES : FAST RESPONDING ENERGY TRANSFER SERVICES E8: fast responding services based on dynamic control mode Dynamic adjustment of the BPT considering complex grid situations and secondary actors for grid services. Using dynamic control mode, SECC is also responsible for ensuring e-mobility needs F4: Energy transfer control based on Dynamic control mode The SECC controls the amount of active and reactive power to be transferred during the energy transfer loop. During the loop the SECC may change the power boundaries and the active and/or reactive power targets based on SA requirements and mobility needs. EVCC will make its best efforts to follow the changes. During the loop the EVCC updates its energy requests in relation with mobility needs
BIDIRECTIONAL POWER TRANSFER (BPT) SERVICES ServiceDiscovery pair messages New services for BPT same logic as Charging Services (Wifi and PLC separated into two services) ServiceDetail pair messages Parameter set for BPT services: 2 control modes : Dynamic and Scheduled Connector (legacy EnergyTransfer Type) Generator Mode : current source BPT Channel
ENERGY TRANSFER LOOP MESSAGES
DYNAMIC CONTROL MODE (NEW) a control mode, without negotiation, where a secondary actor system controls the power flow fulfilling user's mobility needs and its own constraints. Mobility need is ensured by EVSE No negotiation, no schedule, no charging profile EVSE sends a single power set point inside the power transfer loop -DC Charging -DC Bidirectional Power Tranfer -AC Charging -AC Bidirectional Power Tranfer EV Service Discovery SECC/SA -AC Charging -AC Bidirectional Power Tranfer (BPT) -AC Bidirectional Power Tranfer (BPT) -Selected service = AC BPT -Selected payment = Plug and Charge Service Detail Payment Service Selection -Connector = Three phase -Generator mode = Current source -Control Mode = Dynamic -EV physical limitations -EV mobility need (departure time & energy need) Charge Parameter Discovery -EVSE physical limitations Power Delivery -EV physical limitations -EVMobility need AC bidirectional power transfer loop -Power control set points Concrete example for AC bidirectional power transfer: Services: fast responding grid services (primary reserve, voltage regulations)
ENERGY LIMITATIONS This parameters are instantaneous values that will change over time during the energy transfer loops. They are calculated, updated and sent during all the energy transfer loop by the EV. Immediate charge could be requested Smart charging services possible Immediate charge is requested 1.
