These electric cars can power a home with two-way V2G charging

During the demonstration against the pension reform on 19 January, the threat of power cuts came back to the fore. It is logical that if the employees stop working, the industries will no longer produce, and for the power plants it can quickly become a real problem. ONE recent scientific study confirmed the Minister of Ecology’s claims about the ability of electric vehicles equipped with V2G (Vehicle to Grid) technology to contribute to energy resilience thanks to their batteries for supply power to the home grid. If you own an electric car, you might want to know if it works with this technology. A system that makes it possible to charge a vehicle but also to use the energy stored in a battery for other uses during the consumption peaks indicated by EcoWatt e.g. But what are the V2G compatible cars, we will explain everything to you.

What is two-way V2G charging?

The new generations of electric cars, such as Mitsubishi or Nissan, are equipped with V2G compatible batteries. This means that the battery can be charged or discharged as needed. The idea is to give your car battery an extra boost when you’re not using it. For example, during peak loads, you can use the power stored in your car for feed your network personal. V2G is therefore a technology that makes it possible to draw the energy stored in your battery to redistribute it on the electrical network.

How does it work?

Thanks to a two-way terminal, the user can then chooses to use the power stored in its battery to supply its network. Let’s take the example of a user recharging his vehicle using solar terminals or company terminals. When he gets home in the evening, he can “plug” his car into the terminal to use the power stored in his car. During peak periods and when needs inside are almost non-existent, the terminal will revert to charging the car. To do this, simply configure the application by, for example, asking it to always have a battery charged at 80 or 100% at seven in the morning. The terminal takes care of ironing your net electricityto charge your car battery.

Which vehicles are therefore compatible with V2G?

Today, only a few models are compatible with V2G technology, and these are primarily company cars. To find out if your vehicle is compatible, simply check the existence of one CHAdeMO socket charge or discharge the battery.

In 2010, an association called CHAdeMO, formed by five major Japanese automakers, proposed CHAdeMO as an 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:

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

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

V2G, what effect for the car battery?

Obviously, if your battery is used to power your network, it will be much more stressed in terms of charge cycles. According to professionals and manufacturers, this technology could actually increase battery life, if the control of the charging and discharging phases is carried out correctly. To use this new technology, the researchers invented an algorithm that increases 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 frequently subject to power outages (earthquakes, typhoons, etc.) and that V2G in this country fulfills a real need of the inhabitants.
