electric cars do not need to make use of the batteries stored electricity, you can sell it to others. In the future, electric will be posting a few euros to earn. However, it is still unclear when – and how long – it works.
up to 1000 Euro per year, experts estimate the possible future holders in addition to merits of E-car. Be paid to you – so the idea – either of the current groups, use the batteries of parked Mobile, as a rule, power buffer for the stability of the grid. Or they result from gains on the electricity market. Who refuels there, cheap, and feeds back later at a higher price, may be pleased with the difference (“Intraday trading”). That’s the theory.
electric cars and the electricity grid: Technical hurdles
Practically a technical hurdle exists first of all: Because the car needs to be able to provide electricity not only to absorb but also to release it again. “Bidirectional Loading” is the appropriate technical term. This master, however, so far, the least E-cars, especially Japanese models such as the Nissan Leaf, the Mitsubishi Outlander or Honda e. In repeatedly affected by natural disasters home to the Autonomous power supply from the car battery is mainly for use in private households is interesting.

In Western Europe, however, the power grid is relatively stable, which is why the car manufacturers do without in this country, largely on the technique. In addition, you are likely to have initially had concerns about the battery durability. Because the constant Charging and Discharging the electricity storage is not good. The low performance in bi-directional Load, but only a little bit stressful. Focus Online The E-mark, here with a Mitsubishi Outlander PHEV, there is for electric cars and Plug-In Hybrid
Bi-directional Loading
The right car is not enough alone for a bidirectional Load, however. Electricity is fed back into the grid, you either need a suitable charger, a conventional wall box for a couple of Hundred euros is not enough. Bi-directional loader currently cost more in 5000 to 10,000 euros. An investment that pays for itself solely through the sale of electricity or balancing power.

fails, The charging technology is expected to be like any new mass technology with high production cheaper. And also the ability to bi-directional Loading is not rocket science – in new E-car types, you likely without any major problems installing it. That has not happened yet, probably not least for regulatory reasons. And normalized to the V2G technology is regulated, among other things, by the ISO 15118, which is yet to be carried out but neither the energy nor the auto industry. This has several reasons – many of them, with the fact that the Norm also regulates the so-called “Plug-and-Charge”technique, in which the charging station no longer recognizes the connected E-car automatically, so that the common, such as complicated fuel cards and App authentication is required. </p The problems of the energy transition
> The question of network stability in the context of E-cars is becoming more and more important, where it goes to the local distribution networks and not to the entire amount of power required. Starting in 2021 power grid operators in several countries to limit the charging current to private stations, in order to prevent local Overloads . “The reserves in the low voltage networks are not so high as is often assumed,” the Austrian current Manager Reinhard Nenning, head of the working group on distribution networks at the Association of Austria’s energy in Vienna. “We have the Problem that we can not provide you with any power. Our nets come in a sweat, if several electric cars in a residential area with 11 or even 22 kW load“, so Nenning. The power grids had been to the growing needs, however, the reserves for a rapidly growing electricity demand due to electric mobility to be too low.

That the power supply Problem in the context of E-mobility has been observed, is unusual. Especially since it is also through the energy transition is exacerbated in Germany by a parallel withdrawal from the secure base-load supply, with coal and nuclear power in front of a unique challenge. A decentralized energy production can also bring benefits – for example, when a solar cell-equipped roof of a Parking lot generates its own energy. But the challenges, which are noted in the part, especially ideologically motivated discussion around climate change, CO2 legislation and the energy transition is unlikely to stay.
current transfer: The legal arrangements
Not just on a technical level, regulations are missing. Legally and financially, it is not yet clear, such as current transfers by private persons are settled into the net, and settled to be hedged. Appropriate models are likely to develop if on the one hand, the technical possibilities on vehicle and infrastructure side are universally available. And on the other hand, the Expansion of renewable energies is progressing. Especially the fluctuating solar and wind power generation requires exactly the control power, which could provide the parked cars.

a triumph of electro-mobile would threaten this business model in the medium term. Because in your water an attractive Alternative to the “would swim between memory”: the used battery. Stationary electricity storage are still very expensive, they are likely to be an increasing number of discarded electric car batteries much cheaper. And so perhaps the first choice for the buffer store.
the Bottom line is the ability to earn money with the E-car yet, only a theoretical one. The decision to purchase a vehicle should you therefore have an impact only on the edge. But who has hope a home charging possibility, perhaps with a photovoltaic system on the roof that may at a future pocket money. More interesting is the V2G technology, but for users on a large scale. Especially companies with big company car fleets could open up the bi-directional Charge, new revenue sources and business models.
