2.2.2 HomePlug Green PHY - Powerline Communication

While the basic signaling is handled by the control pilot, the DIN 70121, ISO 15118 standard (Road vehicles - Vehicle-to-grid communication interface) is developed to allow more advanced communication between electric vehicles and charging stations. This standard introduces secure communication and high-level data exchange, including encryption and authentication mechanisms.

ISO 15118 standardizes the communication of the charging parameters, such as voltage levels, current limits, and charging states which are constantly updated during a charging session. In addition to that, the standard enables advanced features like plug and charge, enabling payment without user interaction or Vehicle-to-Grid (V2G) for bidirectional power transfer.

Part 3 of ISO 15118 defines the HPGP standard as physical layer for this kind of communication. The HPGP standard is a powerline communication (PLC) architecture, operating in the 2MHz to 30MHz frequency band and supports data rates up to 10Mbps. The TIDA-010939 supports the Lumissil® IS32CG5317 HPGP device. The PHY is connected to the AM62L through a serial-peripheral interface (SPI).
