Data transmission between electric vehicle and charging station as per ISO 15118-3
The international standard ISO 15118 defines intelligent charging of electric vehicles, the "smart charging" for AC and DC charging stations. This permits amongst others active charging control, plug & charge authentication, smart grid integration as well as other services.
When smart charging, the charging station (EVSE) communicates with the electric vehicle (PEV) via charging cable using the powerline standard HomePlug Green PHYTM according to ISO15118-3. The data stream will be modulated to the pilot line of the charging cable with this.
The INSYS Powerline GP establishes the point to point connection between EVSE and PEV so that the EVSE controller can communicate with the PEV via an Ethernet link.
The INSYS Powerline GP operates the layers 1 and 2 in the ISO-OSI model:
