California Energy Commission has funded 10 “Responsive, Easy Charging Products With Dynamic Signals (REDWDS)” projects to demonstrate and deploy EV charging products that can respond to dynamic grid signals. Three REDWDS projects have significant bidirectional charging scope led by Kaluza, Bidirectional Energy, and dcbel. Lawrence Berkeley National Laboratory (LBNL) is funded by Southern California Edison to work with these three bidirectional charging technology providers to document their use cases, approaches to communicate grid and price signals, charging control and optimization, customer experience, interoperability features, and up-to-date progress and challenges in their projects. San Diego Gas and Electric has also been working with these REDWDS projects to showcase value stack for scaling. In addition, SDG&E is demonstrating using bidirectional community EV charging and discharging along with solar and battery to backup critical local water supply loads during Public Safety Power Shutoff (PSPS) events.
