V2H noun [U]
abbreviation for vehicle-to-home: a system that allows electric vehicles to transfer the energy stored in their batteries back into the electrical system of a home
The idea is that electric vehicles, when not in use, often have surplus energy stored in their batteries. Rather than letting this energy go to waste, V2H systems enable the vehicle’s stored energy to be fed back into the home’s power grid, powering household appliances and systems. With V2H, EV owners can potentially save on their electricity bills and make more efficient use of their renewable energy resources, while also providing a backup power source for their homes.

Currently, bidirectional charging is available in only a handful of cars. But its popularity is growing: GM announced that the technology will come standard in all its electric vehicles by model year 2026.
