Arrows V2G reference design accelerates EV charger development
Arrow Electronics has unveiled a data-communication reference design for electric vehicles (EV) charging that combines software stacks for state-of-the-art protocols and a HomePlug Green PHY hardware module. The reference design helps accelerate time-to-market for EV supply equipment (EVSE) meeting the latest industry standards.
The software, developed at Arrow’s engineering solutions centre in Gdansk, contains protocol stacks for ISO 15118 Vehicle-to-Grid (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.
Completing the reference design, the hardware communication module contains the Lumissil CG5317 HomePlug Green PHY low-power communications transceiver. This integrated circuit is HomePlug compliant and AEC-Q100 Grade 2 qualified, allowing operation from -40°C to 105°C.
The Arrow GreenPHY reference design board is easily connected to various evaluation boards for testing and development. Turnkey conformance tests are also available to help verify correct operation when connecting to various popular EV models. This saves significant time and development costs to secure the necessary product-level approvals.
The software stack has recently been deployed by Arrow engineering services provider eInfochips in their DC charger design. THE DCFC is tailored for small and mid-sized commercial and public EV charging. With support for both U.S. and EU markets, and compliant with CE, FCC and UL standards, DCFC can also be managed remotely by drivers and charge point service providers via the eInfochips EVWER platform and mobile app.
