Bad news for those who think that electric vehicles will collapse our grid: Electric vehicles will serve to make our grid more durable, cleaner and cheaper. They will do this by providing a bidirectional flow of electricity when plugged into the charger.

Actually V2G (vehicle to grid) In other words, the electrical technology flowing from the vehicle to the grid has been used in some parts of the world until now, but since the socket using it was CHAdeMO DC (Direct Current), it was only supported in Nissan Leaf type vehicles. However, in our world we now use the CCS type socket standard. But until now, this socket type did not officially allow bidirectional flow. According to the latest good news in 2025 support will come and bi-directional current will be provided via CCS with AC, that is, alternating current.

Moreover, since DC charging systems were very expensive, the infrastructure investment was very high, but a bi-directional AC charger is expected to be as cheap as one-way.

In this way, when you leave your car in the garage, the vehicle will first charge itself and then, while remaining connected to the socket, will provide electricity to the grid when the grid needs a sudden increase in electricity. In this way, the network will rent from you instead of spending money on batteries or natural gas conversion plants that will be put into service instantly at very high prices.

Reduces fossil fuel use

Another area of ​​use will be to reduce the use of fossil-based fuels. All world grids, including ours, rely on the most expensive natural gas cycle power plants to obtain instant electricity during peak usage hours. But burning natural gas is not environmentally friendly and is now very expensive. Keeping gigantic power plants ready and operating only for 3-4 hours of use in the evening hours causes the unit price of the electricity produced there to be extremely high.

Will be tested in England

Starting in the UK in September 2024 It will end in March 2025 During the trial period, this technology will be used through special bi-directional AC chargers and will include many standard models we know.

Who can apply?

to this system Kia, Hyundai and MG Those who own at least two vehicles from the vehicle list can apply. In the system, a bidirectional 7 kW double-socket charging station from JLR will be used, as vehicles are no longer expected to remain connected to the grid only while charging, and then have the socket plugged in while waiting.

Crowdcharge The project, led by the company, has also received financial support from the British state. Maybe what you’re wondering is how much my electricity bill will decrease if I connect my vehicle this way. Although the answer to this question is a bit complicated, it is said that a discount of between £ 150 and £ 500 per year, that is, between 7 thousand and 22 thousand TL, can be provided. Of course, let’s add that electricity prices in England are more expensive than ours, so they may be less for us too.

There are over 1 million vehicles in the UK. If these vehicles had an average of 50 kWh batteries, 50 million kWh or 5,000 MWh or in other words 5 GWh’lik storage is already available. If power is drawn from a vehicle with 11 kW as instant power, 1.1 GW energy can be withdrawn. This means as much power as a nuclear reactor. Of course “do they all connect at the same time?” You may say, but there are 33 million cars in the UK. If they all convert, there is a very high probability that 1/33 of them will be instantly connected.

The important thing here is that legal regulations should be made immediately in every country, including ours, and the way should be paved for companies that want to serve you in this regard. In this way, the relationship between the charging station, the electricity network operator and the electricity distribution company needs to be established.
