Vehicle-to-grid (V2G) is and has been a goal for those looking at the long-term future of electric vehicles and those aiming to maximize system-wide resiliency and efficiency. To date, V2G has only rarely been attempted, usually in the form of the more limited vehicle-to-home (V2H) implementations.
But the whole concept got a boost recently when something called Powershare appeared on the Tesla website along with the long-awaited rollout of CyberTruck. For home backup purposes (V2H), Powershare offers maximum continuous 11.5 kW at a nominal 240 V AC, certainly an impressive capability.
But making V2G a widespread reality requires additional developments on both the grid and vehicle sides.
