VW Groep gaat ook naar bidirectioneel laden van hun EVs, 2022 ergens.

Dus de EV kan ook vermogen leveren aan andere ver- of gebruikers of naar het net (V2G)

Andere merken doen het al of hun hardware is al voorbereid, t.t.z. enkel een software-aanpassing.

Volkswagen has confirmed that it will switch all of its MEB-based electric vehicles to support bidirectional charging starting next year.

It could give a big boost to vehicle-to-grid technologies.

Vehicle-to-grid

During the early days of the electric vehicle revolution, the industry was cautious about the use of battery packs as longevity was a big question.

But now the industry as a whole is getting more confident that well-managed battery packs can last a long time, some see them as underused assets.

Some EVs have big battery packs enabling 200+ miles of range, but they travel fewer than 40 miles more days.

As the fleet of electric vehicles grows in some markets, controlling when electric vehicles can charge on the local electric grid has great value for balancing the load and avoiding running expensive and polluting peaker power plants.

If those electric vehicles could also put power that they don’t need back into the grid, that would have even greater value.

The technology is often referred to as “vehicle-to-grid.”

An electric vehicle with bidirectional charging capacity can send power pack into the grid, or a home, or even another electric vehicle.

Some companies and electric utilities have been exploring the idea of using a fleet of electric vehicles equipped with bidirectional charging to help balance the grid when needed.

With big enough fleets, it could provide very valuable grid services by taking back some power from thousands of vehicles that don’t need it. In return, those EV owners would get compensated by the electric utility for the use of their battery pack.

The problem has been that there are only a limited number of electric vehicles equipped with bidirectional charging capability.

The Nissan Leaf is the most popular EV with the capacity, but that’s about it.

However, there are many new EVs coming with the capacity. The new Hyundai Ioniq 5 is equipped with the technology, and Tesla has commented that all future vehicles will be equipped with bidirectional charging capacity.

Now Volkswagen is adding its name to the list.

VW going with bidirectional charging

We knew that the automaker had been working on the technology since they unveiled a wall charger with bidirectional charging capacity last year, but they didn’t say when the capacity would come to the vehicles.

Now the German group has confirmed that every new VW EV based on the MEB platform is going to be equipped with bidirectional charging capacity starting next year (via Handelsblatt):

“The test vehicles are running, we are in the last pulls with the preparations,” confirms VW Development Board Member Thomas Ulbrich in an interview with the Handelsblatt. From 2022 onwards, every electric car from the Volkswagen Group that is developed on the basis of the MEB (“modular electrification kit”) electrical platform can not only charge the electricity but also return it to the grid. In addition to VW, the MEB is also used by the sister brands Audi , Skoda and Seat-Cupra.

The automaker could produce as many as 300,000 vehicles with the capacity next year.

It would result in big enough EV fleets with the capacity to have big impacts on the electric grid.

Volkswagen plans to be involved in the process to make sure it benefits everyone involved, including the electric vehicle owner.

Furthermore, bidirectional charging also offers other advantages, like the potential to provide backup power to your home when needed.

Voorlopig grootste snellaadstation komt in Coalinga, CA. (Harris Ranch)

Er staan reeds 18 Tesla Sucs V2 (150 kW) maar er komen er nog minstens 80 bij (V3 250 kW), in geel kader op luchtbeeld.

Dus vermoedelijk ~100 totaal.

Tesla Canada omzeilt een domme subsidieregeling door een model 3 aan te bieden in de katalogus die niemand gaat kopen, want gekastreerd naar 151 km rijbereik en zonder basis autopilot.



of Canada-Tesla configuratie: https://www.tesla.com/en_ca/model3/design#overview

Maar dit levert volgens de ambetantenarenregeltjes wel op dat de normale versie met 426 km bereik toch een subsidie van 5000 Canadese dollars krijgt. Benieuwd hoelang dat gaat duren.

Of hoe subsidieregels ook vindingrijk maken (was in België ook ooit met het vermogen via software wat af te pitsen, om hogere wegtaks te vermijden)

Toekomstige Autopilot FSD Beta software V 9.0 gaat werkelijk zonder radarinput zijn.

Tesla is niet alleen die dit doet, MobilEye testwagens reden rondom Jerusalem ook in die only vision configuratie.

Elon Musk legt het in detail uit:

Citaat:

A recent set of updates from Elon Musk has revealed that Tesla is looking to eventually update its Autopilot and Full Self-Driving suite to a camera-based system. This means that in the future, Tesla’s all-electric vehicles would be navigating themselves and performing driver-assist functions without the use of components such as radar.

Musk’s update came as a response to a post from Tesla owner and FSD Beta user @WholeMarsBlog, who shared a clip of his Model 3 navigating away from a parking lot to its destination without input from its driver. In his response, Musk noted that FSD Beta V9.0, which has been highly-anticipated by the EV community, is almost ready.

Almost ready with FSD Beta V9.0. Step change improvement is massive, especially for weird corner cases & bad weather. Pure vision, no radar.

— Elon Musk (@elonmusk) April 9, 2021

Elaborating further, Musk explained that the V9.0 update should improve the FSD Beta’s performance in corner cases and bad weather, which remain challenging to the advanced driver-assist system today. But this was not all, as Musk noted that the update would be “pure vision, no radar.” When prodded further, the Tesla CEO admitted that Tesla eventually plans to get rid of radar altogether in its future vehicles.

Unsurprisingly, Musk’s statements about Tesla’s impending removal of radar attracted its own fair share of critics, many of whom argued that a pure vision approach is a step backward. This is especially notable as Tesla is already using fewer sensors for its driver-assist systems compared to competitors like Cruise and Waymo, both of whom rely on lidar and high-definition maps to navigate.

Musk responded to these concerns, highlighting that ultimately, vision has the potential to be far superior to radar.

Sensors are a bitstream and cameras have several orders of magnitude more bits/sec than radar (or lidar).

Radar must meaningfully increase signal/noise of bitstream to be worth complexity of integrating it.

As vision processing gets better, it just leaves radar far behind.

— Elon Musk (@elonmusk) April 10, 2021

“When radar and vision disagree, which one do you believe? Vision has much more precision, so better to double down on vision than do sensor fusion. Sensors are a bitstream and cameras have several orders of magnitude more bits/sec than radar (or lidar). Radar must meaningfully increase signal/noise of bitstream to be worth complexity of integrating it. As vision processing gets better, it just leaves radar far behind,” Musk explained.

Tesla’s approach to full self-driving is partly based on the notion that humans do 100% of their driving through vision alone, without any radar or lidar use. This was highlighted by Tesla executives since Autonomy Day back in 2019, when the company unveiled its custom FSD computer. As for concerns about whether cameras could provide the same level of safety as radar in detecting what is happening several cars ahead, Musk noted that there’s a high probability that vision could perform just as well.

These things are best thought of as probabilities. There are 5 forward-facing cameras. It is highly likely that at least one of them will see multiple cars ahead.

— Elon Musk (@elonmusk) April 10, 2021

“These things are best thought of as probabilities. There are 5 forward-facing cameras. It is highly likely that at least one of them will see multiple cars ahead,” Musk said.

Tesla is not the only company in the market that is looking into a vision-only approach. Last year, Intel Corp released a video of an autonomous car from MobilEye that was navigating around Jerusalem for about 20 minutes. Unlike other self-driving vehicles, MobilEye’s car was only equipped with a suite of cameras and nothing else. The brief video was impressive, showing the MobilEye autonomous car going through four-way intersections with no traffic lights, as well as inner-city lanes that required the vehicle to avoid pedestrians.
(btw, buiten USA rijdt niemand met FSD Beta, enkel een 1000-tal ervaren testrijders)
