Plug-In Electric Vehicle Smart Charging in California (XBOS-V)

Plug-In Electric Vehicle Smart Charging in California: Open Source Protocol for Grid Operation and Ratepayer Benefits at Residential and Small Commercial Settings (XBOS-V)

This interdisciplinary project focuses on controlling the charging of plug-in electric vehicles (PEVs) at residential and small commercial settings using a novel and flexible open-source, open-architecture charge communication and control platform.

XBOS-VThis software-based platform known as “XBOS-V” (Open eXtensible Building Operation System/Vehicles) will be embedded in the context of overall utility and residential/business electrical and building automation systems, lending itself to potential broad implementation by commercial interests.

The integrated project will also focus on the key issues associated with the development of the open-source platform including assessment of user needs and grid operation and ratepayer benefits, grid security considerations, and the potential for PEV charge control to lead to increased ability to accept intermittent renewable energy for California’s electrical grid.

The platform would be developed to build on previous work for vehicle-grid solutions, including through such protocols as OpenADR, SEP 2.0, Zigbee, SAE J1772, and ISO 15118. The project brings together a group of researchers from the University of California – Berkeley and BMW North America LLC to also conduct an in-depth study that will gather key information learned from the “i ChargeForward” project by Pacific Gas and Electric Co. and BMW.

The project will use key insights and observations from the pilot project to inform the development of the Open XBOS-V platform and associated grid and user benefits analysis. Up to 100 participants are expected in the i ChargeForward program for BMW i3 drivers, starting in Summer 2015.
