Cheaper power on the home network thanks to EVs
Cheaper power in the domestic network is something that will increasingly concern the world’s electricity infrastructure since the increase in electric vehicles will impose particularly high energy requirements. But will EVs ultimately be the solution to the problem?
The integration of the electric car into the domestic network could offer even greater advantages if combined with a photovoltaic system. Excess photovoltaic electricity could be stored in the car and used later as needed.

The idea is simple, but also innovative. The high-voltage battery of the electric car can not only be charged through the wall-box at home, but can also power the house, as an independent means of storage. The battery of an electric car can provide a house with the required energy for about a week, as long as there are no major needs.
Two-way charging at home, known as Vehicle to Home (V2H), can make a profit even without the availability of solar panels, as the owner of the electric car can fill his batteries at night, when the price of KWh is lower, and feed it into the system when the price is increased at peak times.

Increasing grid stability, reducing electricity costs and contributing to climate protection are the key elements that can be achieved by integrating electric cars into the networks of different providers.
Two-way charging is mainly focused on cases where the owners of the house use their own photovoltaic system to take advantage of the cost-optimized charge with the household-produced electricity.
Also, businesses that will move to new and renovated offices in the coming years will have to find parking spaces with wiring for electric vehicle charging points, according to a European Commission directive on the energy performance of buildings.
The directive was announced a few days ago to help the EU achieve its long-term climate and energy targets. The EU’s vision is to achieve a zero-emission and fully decarbonised building stock by 2050.
