These electric cars can power a home with bi-directional V2G charging

During the demonstration against the pension reform on January 19, the threat of a power cut came to the fore again. Logically, when the employees stop working, the industries stop producing and this can quickly become a real problem for the power plants. A recent scientific study confirmed the Environment Minister’s claims regarding the ability of electric vehicles equipped with V2G (Vehicle to Grid) technology to contribute to energy resilience thanks to their batteries Feed electricity into the home network. If you own an electric car, you might want to know if it works with this technology. A system that allows you to charge a vehicle, but also to use the energy stored in a battery for other purposes during the consumption peaks indicated by EcoWatt for example. But what are the V2G compatible cars, we explain everything to you.

What is bi-directional V2G charging?

The new generations of electric cars, such as the Mitsubishi or Nissan, are equipped with it V2G compatible batteries. This allows the battery to be charged or discharged as required. The idea is to give your car battery a second use when you are not using it. For example, you can use the electricity stored in your car during peak consumption periods feed your network personally. So V2G is a technology that makes it possible draw the energy stored in your battery to redistribute it on the power grid.

How it works ?

Thanks to a two-way terminal, the user can then choose to use the electricity stored in its battery to power its grid. Let’s take the example of a user who charges his vehicle via solar terminals or company terminals. When he comes home in the evening, he can “plug” his car into the terminal to use the electricity stored in his car. Off-peak and when demand inside is almost non-existent, the terminal recharges the car. To do this, simply configure the application by asking it, for example, to always have a battery charged at 80% or 100% at 7 a.m. The terminal does the ironing mains powerto charge your car battery.

So which vehicles are V2G compatible?

Today only a few models are compatible with V2G technology and this mainly concerns company vehicles. To find out if your vehicle is compatible, simply check for one CHAdeMO socket Charge or discharge the battery.

In 2010, an association called CHAdeMO, formed by five major Japanese automakers, proposed CHAdeMO as the international industry standard for electric vehicles.

The cars compatible with this technology are:

  • Plug-in Hybrid Vehicles (PHEV)
  • Battery Electric Vehicles (BEV)
  • Hydrogen Fuel Cell Electric Vehicles (FCEV)

Today only a few specific models are V2G compatible:

  • The Nissan Leaf
  • The Nissan e-NV200
  • The Peugeot iON
  • The Mitsubishi Outlander PHEV
  • The Mitsubishi iMiev
  • The Citroën C0.

They all work with the V2G charging station powered by DREEV (EDF Group).

V2G what impact on the car battery?

Of course, if your battery is used to power your network, it will be put under a lot more stress in terms of charge cycles. According to professionals and manufacturers, this technology is could actually increase battery life, if the management of the charging and discharging phases is carried out correctly. To take advantage of this new technology, the researchers invented an algorithm that Battery life and minimize V2G-related degradations. Currently, Mitsubishi vehicles would be the most successful in this area of ​​V2G, which is likely to expand in the coming years. It must be said that Japan is often affected by power outages (earthquakes, typhoons, etc.) and that V2G meets a real need of residents in this country.
