Arrow Electronics, Inc. has developed a data-communication reference design for electric vehicle (EV) charging. The vehicle-to-grid (V2G) reference design combines software stacks for state-of-the-art protocols and a HomePlug Green PHY hardware module to accelerate EV charger development.

The software, developed at Arrow’s engineering solutions center in Gdansk, Poland, contains protocol stacks for ISO 15118 V2G communication. There is also sample application code, as well as support for Open Charge-Point Protocol (OCCP) and Control Pilot interfaces as defined in IEC 61851 and SAE J1772. The hardware communication module contains a Lumissil CG5317 HomePlug Green PHY low-power communications transceiver.
“V2G is required for fast DC chargers and quickly becoming the preferred communication protocol for AC charging. It increases charger functionality with future-proof capabilities, including wireless charging, bi-directional power transfer and plug-and-charge feature,” said Vitali Damasevich, director of engineering for Eastern Europe and Arrow’s engineering solutions center EMEA, in a statement.
“Our reference design enables EV charger producers to quickly adopt the new standard, relieving much of the software development needed by including the ISO 15118 protocol stack, and also providing a HomePlug Green PHY module to assist hardware design and integration,” he added.
Arrow said the Green PHY reference design board can be easily connected to various evaluation boards for testing and development.
In addition, Arrow’s engineers can help customers integrate their selected microprocessor or microcontroller platform when finalizing the design for production and turnkey conformance tests are available to help customers verify correct operation when connecting to various popular EV models. The EV charging reference design is available now.
