Toyota and San Diego Gas & Electric Company announced that they have agreed to collaborate on vehicle-to-grid (V2G) research for battery electric vehicles (BEVs) using a Toyota bZ4X. The V2G research will explore bidirectional power flow technology that enables BEV owners to both charge their vehicle’s batteries from the electric grid and discharge electricity from the batteries back to the grid. V2G technology has the potential to support customer needs through improved energy reliability and resilience, the integration of renewables, and the possibility of reduced electricity costs.

The collaboration between SDG&E and Toyota’s Electric Vehicle Charging Solutions (EVCS) team aims to find synergies between the needs of BEV owners and the needs of the electricity grid, as well as explore how to communicate with BEV owners about the potential benefits of bidirectional capabilities.

The V2G research will take place at SDG&E’s campus in San Diego, California, using Fermata Energy’s bidirectional charger and V2G platform. SDG&E employs a highly knowledgeable clean transportation team that has implemented a variety of EV charging infrastructure programs.

With insight gained from the V2G research collaboration, SDG&E and Toyota aim to identify current and future customer benefits that can be achieved through new products and services. The pilot will also assist SDG&E in understanding the infrastructure needed to enable the rapid growth of EV charging infrastructure, both in public and private settings, and to further stabilize the power grid during peak hours.
