Volkswagen wants its customers to make money thanks to the V2G technology of its electric cars – Technology – Hybrids and Electric

The Volkswagen Group has confirmed that all the electric cars it manufactures from next year on the MEB platform will incorporate V2G bi-directional charging technology (vehicle-to-grid). The rest of the group’s brands, Audi, Skoda, Seat and CupraThey will also be able to count on this possibility. The German manufacturer has been working with this technology for some time, and with the presentation last year of its charger with bidirectional charging capacity, it already warned of its interest in it. The 300,000 electric vehicles that is scheduled to be assembled next year with this technology, they can have a great capacity to influence the electrical network, so it will be in charge of making sure that everyone involved benefits from it.

Drawbacks of V2G technology?

Cars are stationary for most of the day, making it easy to recharge flexibility. Bi-directional charging allows when an electric car is recharging, energy to flow both from the electrical network to the car and from the car to the network. In this way, a double function is achieved, since in addition to increasing the use of renewable energies, a reduction in electrical costs is achieved thanks to the possibility offered by the energy storage in batteries. Through V2G systems, electric cars have great potential as drivers of the energy transition, as they are capable of absorbing the generation peaks of the system.

V2G technology can be found in some electric models for years. The system has been explored and implemented by Japanese manufacturers such as Honda or Nissan. It will also include the Sono Sion, a car with solar technology that could not forget about it, or the future Ioniq 5, which will also implement it. However, for now it has not been considered an extra that could influence the purchase intention. Quite the contrary, on some occasions it has even been considered a negative characteristic since its use accelerates the discharge and discharge cycles of the battery and therefore can increase its degradation.

An argument used by Elon Musk himself not to integrate it into his electric vehicles, alluding to the potential for accelerated battery degradation. However, reverse engineering has detected that the Model 3 is already mounting a bi-directional charger that would take advantage of the large capacity of its batteries and the electrical ecosystem that surrounds its product offering.

Today, battery technology and battery management systems have evolved in such a way that the industry increasingly relies on reducing degradation caused by more frequent charging and discharging. In many cases, the battery of an electric car becomes an underused component which could get more out of it. In addition, the increase in the number of electric cars can cause problems in the supply network, so that the control of charging times will end up being an indispensable requirement for the proper functioning of the network and a greater use of renewable energies.

V2G volkswagen VW Power Day

Volkswagen presented its two-way charging system at its recent VW Power Day event held on March 16 and 17 this year.

The Volkswagen V2G

The presentation of Volkswagen’s V2G system took place during the last VW Power Day held on March 16 and 17. With the announcement that it will be integrated into its electric cars as of next year this scenario could speed up quickly. Last year, the German manufacturer already hinted at its intention to implement this technology with the presentation of a bidirectional wallbox capable of reaching 22 kW of power. Through the Web Handelsblatt, Volkswagen has confirmed that all its models that they develop based on the MEB platform will have bi-directional charging from next year.

Volkswagen’s head of electric mobility, Thomas Ulbrich, affirms that they are completing the tests with vehicles that already equip the system: “As of 2022, every electric car of the Volkswagen Group that is manufactured on the basis of the MEB electric platform not only it will be able to charge electricity, but also to return it to the grid ”, which implies that Audi (which had already announced it), Skoda and Seat and Cupra will also have this technology.

If Volkswagen meets its forecasts and puts on the market next year 300,000 electric cars, the fleet of cars with this technology would have a great capacity to influence the management of electrical networks. Therefore, Volkswagen ensures that its intention is to be involved in the entire process so that it can ensure that it benefits all those involved, including their vehicle owners that, in addition, they will have the possibility of supporting the energy in their own home when necessary.

A pilot project related to V2G technology, launched by Nissan in Germany, shows that an electric car can be integrated into the energy market and generate income for its owner. In one week each electric car was able to supply 8 kWh to the grid receiving in return 20 euros, which would suppose, considering 50 weeks, a total of 1,000 euros per year. V2G technology is particularly interesting for fleet operators. Its main drawback is both charging technology prices and regulatory hurdles. On the other hand, the project showed that increasing the frequency of battery charging and discharging they do not shorten their lifespan.

Electric vehicles, renewable energy and smart charging, the pillars of the Astypalea island project.

Last year, the Volkswagen Group and the authorities of the Greek island of Astypalea presented a project to make this place a true flagship of the world. sustainable future through electric mobility, smart transport solutions and green energy production. The Volkswagen electric cars and SEAT electric scooters and scooters will become the key to achieving it, supported by a intelligent transport system based on digital mobility, renewable energy sources and the V2G recharging network.

Among other actions, the renewable energy generation systems through photovoltaic and wind installations that will feed a wide recharging infrastructure that will allow the establishment of an intelligent system to control the stability of the grid, thanks to V2G technology.
