V2G, V2L, V2X: definition
Today, with new technologies, charging stations aren't just used to power electric vehicles. Technologies such as V2G, V2Land V2Xare innovative in that they bring an additional function to electric cars and charging stations.
It's true that these terms are rather confusing, but they're essential to know. The principle behind these technologies is simple: to use the energy of an electric car to redistribute it to another player, hence the name "vehicle-to". the name "vehicle-to"..
There are 5 such technologies:
V2G (Vehicle-to-Grid)
Visit V2G (vehicle-to-grid)is a technology that enables energy from the battery of an electric car to be return energy from an electric car's battery to the grid. In other words, when you recharge your electric vehiclethe energy stored in the battery will be redistributed to the grid, to power electrical appliances in your home.
For this system to work, the installation of a Wallboxcharging station is essential.
In fact, if you're wondering whether this technology is available in France, it already is, since it has been certified as being a solution for balancing the French electricity grid. It's also one of the things you may not have known about charging stations.

V2L (vehicle-to-load)
Also known as "Vehicle for Recharging this technology enables electric appliances to be recharged using the electric car. The V2L is also present on the Hyundai IONIQ 5, the Kia EV6 and the MG4.
With this technology, it will be possible to recharge any device with energy from the electric car batterylike a laptop, an electric guitar or a bicycle. This can be very useful if you're going on vacation and have nowhere to recharge your devices. In that case, your electric car will be your savior!
V2H (vehicle-to-home) / V2B (vehicle-to-home)
As its name suggests, the V2H (vehicle-to-home) is based on the same principle: the energy from an EV's battery is redistributed to the electrical grid, but this time the home power grid. For the V2B (vehicle-to-building)this technology is similar to V2H, except that for V2B, the energy stored in the vehicle's battery, will be redistributed in a building.
As with V2B (vehicle-to-building)or V2Git is necessary to have a Wallbox as a charging point, i.e. a bidirectional charging.
V2X (vehicle-to-everything): a multifunctional technology
Why multifunction technology? Because V2X (vehicle-to-everything) combines all the functionalities mentioned above. It's all-in-one.
It's a technology that carmaker Hyundai would like to introduce on its next electric cars. On the one hand, to make better use of renewable energieson the other, to reduce energy consumption on local power grids. In the future, electric cars will be able to redistribute energy throughout the power grid, whether in buildings or homes.

V2G, V2L, V2X: what are they for?
As we touched on earlier, these technologies bring new functionalities to electric vehicles and charging stations. Unlike combustion engines, these technologies provide solutions to current economic and energy issues, such as :
- the cost of electricity: we are all currently faced with rising electricity prices, both for individuals and businesses.
- back-up in the event of a power cut: electric vehicle batteries are an alternative way of recharging your other appliances.
- added convenience: having recharging facilities in your own car gives you added convenience. So you don't necessarily have to stop at a rest area to recharge your bike or computer. Everything is at your fingertips!
What are the limits of these technologies?
These technologies are certainly innovative, but are there any limits? If so, what are they?
As we mentioned earlier, just to connect an electric vehicle to an object, it's necessary toa specific Wallbox charging point.
While in France V2G technology technology is not yet widespread throughout the country, it has been well known in Japan for some time, thanks to the Japanese CHAdeMO charging standard. In Europe and America, the most widely used charging standard remains the Combo CCS in 1ʳᵉ position. With this standard, V2G technology won't be on our electric vehicles and charging stations until 2025.
Another limitation is that, like many components, the EV battery degrades with each charge. With these different technologies, electricity has to make several round trips, and this could have repercussions on the cells of the lithium-ion battery cells and, subsequently, on the vehicle'srange. However, these impacts are low, estimated at 2.3% loss per yearaccording to a GEOTAB study.
To further limit battery degradation when, for example, the V2G system is mobilized, the solution would be to use an intelligent control algorithm. intelligent control algorithm on charging stations. The aim is to improve battery battery life by controlling by controlling the recharging of the electric vehicle.
In fact, automakers are well aware of this problem, and are continuing to improve these technologies to make them even more efficient in the long term.

Which electric cars have these technologies?
In fact, several automakers have already integrated these technologies into their electric cars, to create a link between mobility and energy. Here are a few examples:
Nissan Leaf
Since 2010, the Nissan has been equipping its electric Leafs with V2Gtechnology CHAdeMO. As one of the first cars to install this feature, it has already been tested by over 7,000 Japanese households and the results have been nothing but beneficial: saving energy and money while smoothing out consumption peaks.
This has been put in place to support the power grid and convert the electric car into a genuine energy source.
Being a family sedan and 100% electricwith folding seats and 435 liters of trunk space, this car is flexible enough to meet every need, whether you're going on vacation for several weeks or just for the weekend.
The Nissan Leaf, which has been on the market since 2011, is still available, and here are the different amounts depending on the finish chosen:
