What is V2G (vehicle to grid) technology?
Vehicle to Grid (V2G) technology introduces the concept of a two-way power flow by allowing the charging and discharging of the electric vehicle battery.
The V2G (vehicle to grid) allows a parked and connected electric car to charge its battery or discharge it providing energy to the grid. One of the advantages of V2G (vehicle to grid) is its ability to compensate for fluctuations in the grid, especially for renewable energy such as photovoltaics and wind energy.
To control the exchange between the car and the network, specific V2G software was developed to manage the vehicle battery charge status and the exchange of energy with the grid network in real-time

In the same way, V2G software can manage the periods when the energy price is more suitable, to charge the vehicle (off-peak times) and provide energy to the grid in hours of big consumption. Electric vehicles introduce the concept of energy storage “under wheels”. – Some countries have business models that pay users for the energy they provide to the grid.
Vehicle to grid (V2G) technology advantages :
Peak Shaving
At times of high energy demand, it is possible to stabilize parameters of the electrical network (or even of a house or building), using the energy available in electric vehicles.
Storage of overproduction
When there is massive production, it is possible to store this excess in the batteries of electric vehicles (typically this happens with renewable energies)
Backup
The stored energy can be used in emergency situations when the power grid fails.
