Terms starting with V
V2G (vehicle to grid)
V2G (vehicle to grid) is bidirectional charging in which the electric car not only charges but also sends energy from its battery back to the grid. In Spain it has no specific payment yet; V2H, by contrast, powers only your home.
V2H (vehicle to home)
V2H (vehicle to home) lets the electric car battery power your home, as back-up in a power cut or to use stored solar energy at night. Unlike V2G, the energy does not go out to the grid.
Video door entry system (videoportero)
A door entry system with a camera on the street panel and a monitor in the home, so you can see and talk to whoever calls and open the door. Modern ones let you answer and open from your phone. In US English, a video intercom.
Voltage (tensión eléctrica)
Voltage is the potential difference that pushes current around a circuit, measured in volts (V). In Spain it is 230 V on single-phase supplies and 400 V between phases on three-phase ones.
