Every scale at the greengrocer is calibrated. In the case of electromobility, however, thousands of non -echo -compliant charging stations provide less electricity than the customer pays. The federal government allows this – so as not to endanger its e -mobility project.

For links on this page, Site receives. A commission from the dealer, Z.B. For marked. More information through calibrated scales in the trade, the consumer knows that the weight of the weight corresponds to reality and that it actually receives what he pays. It is different with electromobility. Because the public charging stations often invite less electricity into the battery than is displayed on the column and the customer pays afterwards.Petrol pumps are calibrated, as are the flow facilities for heating oil or the domestic electricity meter. The state oak offices that ensure that the measuring devices work correctly are responsible for the review. Apparently other laws only apply to charging stations.

Deviation in charging stations up to 20 percent?

As early as November 2017, the oak offices published an instruction, which the operators of the charging stations have a gallows period until 1. April 2019 granted. Until then, corresponding measuring devices should be installed and as long as the operators should calculate a flat -rate price discount of 20 percent, which indicates how much the displayed but not delivered quantities are likely. However, nobody really knows how much the actual charge deviates from the invoice.

But the gallows period passed unsuccessfully. The charging station operator Ionity told the "Munchner Merkur" in February 2019 that corresponding measuring devices are not available for the speed loaders loading with direct current. A reliable statement of how much electricity actually flowed into the battery of the electric car was not possible at all. This still applies to a third of the quick charging facilities in Bavaria and a quarter in Lower Saxony. Then it should hardly look different in the rest of Germany.

Charging column expansion should "do not disabled"

While the e-car owners pay the colliery, the matter remains for the pillar operators without consequences: one does not want to hinder the charging stone structure, quotes this "Handelsblatt" The Bavarian State Office for Weight and Measure, fines are not raised and the unequal charging stations remain on the network. Otherwise Bayern fear a collapse of the entire charging infrastructure. And that is still quite poor anyway. Because everything is still missing: regenerative energies, on electricity and just in the charging infrastructure. So the state authorities prefer to take the broken law.

Of the "Munchner Merkur" goes out of several thousand charging stations that are not calibrated. After all, there is a survey among the manufacturers of measurement facilities and charging stations of the working group law of the funding program Information and communication technologies at the Federal Ministry of Climate and Economy, which is open in five rounds that calibrating measurement devices are not or hardly present and at the beginning of 2022 are before the market launch.

Tariff jungle at charging stations

In addition, there is a jungle of tariffs and offers of the different energy suppliers and also the car companies. Basically, the faster the load, the higher the price per kilowatt hour.At high-performance charging stations from Ionity, the kilowatt hour costs 0.79 euros almost everywhere, exceptions are e.On/Innogy and EWE with 0.49 cents, but then a monthly fee of 9.90 euros (EWE) or a fee per load (E.On/innogy) of 4.95 euros. With certain subscription models you can get the charging current cheaper. Nevertheless: Without a calculator, the actual costs can hardly be calculated. And besides, according to the calibration authorities, you don’t know exactly whether the amount of energy invoiced was even saved in the battery.

ADAC test shows additional consumption when charging

The ADAC tested how big the shrinkage can be in practice at several current electric cars. The Reichste giant Ford Mustang Mach-E Extended Range and Polestar 2 create 480 km in the ADAC ECO test. To extend the lifespan, batteries are only in a certain one "window" loaded and never 100%, so there is always a difference between gross and net content of the battery. The PS-strong electrical-Mustang needed a load of 104.3 kilowatt hours for 98.7 kilowatt hours of battery capacity, 88 of which can be used, of which 88 are usable. 18.5% of the charged and paid electricity are therefore not used. This is what makes the quick charging station 12.87 euros; Mind you per load, with total costs of 82.40 euros (calculated at 0.79 euros per kWh with a quick loader).

With a conventional diesel engine and a price of 1.50 euros per liter, that would be 8.6 liters of diesel that you pay but cannot use. Just imagine, you pour the last eight liters on the asphalt of the petrol station when refueling. In the worst case, electric car drivers are doing this if they are at the "false" Charge.

As if you were spilling eight liters of diesel

Of course, this waste in smaller models is absolutely reduced. But not relative. With one of the best-selling electric cars, the Renault Zoe, 41.4 can be used by a battery capacity of 44.1 kWh, 49.5 are required for a full load of 243 km. In the ADAC test, almost 20 percent of the invited and paid electricity was lost here. The customer pays 6.39 euros for which he does not get anything. All of this data was determined by the ADAC of charging stations that are not calibrated.

Charging columns would have to be retrofitted

According to the survey cited above, eight manufacturers of charging stations or measuring devices had completed a so -called conformity assessment procedure, nine are not yet so far. It is about charging stations with 50, 150 and 350 kW. The authors of the study assume that the successfully approved facilities will not be available until well into 2022, i.e. manufactured in series, for example to retrofit existing charging stations. They also find that the expectations of the manufacturers were far too optimistic about the 2019 and 2020 surveys.

How to recognize soaked columns

Until electric car drivers can load properly, there is still a lot of time passing – and it will be expensive. Because the already established, not compliant columns must be retrofitted. The costs are specified between 500 and 900 euros per measuring unit. New ichrechts-conforming 50 kW charging stations beat with approx. 19.000 euros per pillar.However, there is a trick for electromobilists to detect the columns that indicate Germany’s largest electric car magazine site: calibrated charging stations therefore have a corresponding symbol, which is usually located directly under the screen of the charging station. "The designation of the m in a black-bordered box and the associated year of the squeegee review are then printed on the column", so site.

  1. Rarely read such a strange article …
    So to the point: there is a pillar "electricity" off and what the car does with it is his thing. 5 … So to the point: there is a pillar "electricity" off and what the car does with it is his thing. If 10 or 20% of the electrical energy is lost in the charger of the vehicle as heat = loading losses, it has nothing to do with the pillar. Zoes are the perfect energy destroyers- we knew for a long time. Other vehicles are between 5 – 10 % if the battery is heated up via PTC during the charging or the interior heating is even less in the battery. The poor pillar cannot do anything for that. When .. calibration .. Nice but unnecessary at the moment. The expansion is more important and the site is looking for a knowledgeable specialist journalist. Thanks!

  2. Question of questions ?
    Question of a combustion driver: The charging station shows the "Quantity" on that is offset. The e-car also shows the value or ? These values are identical or not ? If so, there is already a certain system behind it…. The whole thing paired with the charging cards and an non -transparent price award does not necessarily make this customer -friendly…. The future price increases for "E-tank" sometimes completely hidden. That in this area all offices and control bodies "Close eyes" actually shows everything. A long away until the mass compatible is……

  3. The column shows what was delivered..
    And that is also calculated. What arrives in the battery depends on the vehicle. The charging electronics have losses, the heating runs, the driver hears radio, the children watch a video … The rest arrives in the battery. That depends on the vehicle and the user. If possible, do not buy a zoe: the loading losses are almost 30%!

  4. What a hype
    … To not bequeathed charging stations. The problem right to Corona. Triggered by the article of an editor who is at e-cars V.A. The hair i. D. Soup sees. Hot is mostly discussed by combustion drivers who constantly emphasize that it never does not apply an electric car, which does not affect the problem at all. Thank you, dear V-people, for your empathy. But the loss due to the lack of calibration of the charging stations, the Z.Z. apparently no one can quantify exactly, never & never is € 6.50 to € 13 per load, as suggested in the article. Here, as mentioned in several posts, physical loading losses & any losses are mixed by non -sufficient. The latter are i.u. Certainly less than the THG revenues that each electric car can achieve from/in 2022 (for me 354 €).

  5. Loading…
    … there will always be physically conditioned when charging with high streams and high performance. However, the customer should only pay for what he was in his battery "pumped in". The loading losses in the battery, i.e. Z.B. "Sensory heating", If he then has to accept as a given fact, the "Charging current" nothing. The consistent application of a clear legal regulation is required here, because according to § 25 of the Eich Act, electricity, gas, water and heat meters must be calibrated if they are used or are available in business traffic.

  6. Interesting
    is of course the phenomenon that obviously, according to everything you read and hear, in reality is only less loaded for money, never again. A shelm who thinks bad.

  7. What is loaded
    depends on the vehicle. The column operator cannot do anything about what the charging electronics destroyed on the way to battery in the form of heat.

  8. License for money printing !
    Very legal, without provoking legal problems. The columns are not calibrated and the corresponding flow meters are not available. And the trade/oak offices are watching. No one would pay 20-25% too much for something just because the seller says that he cannot quantify exactly how much was sold. But this is apparently not a problem for the highly subsidized e-mobility, there I also pay 80 cents per kilowatt hour. Or just for 0.8…

  9. Does not correspond to the facts ..
    Load losses are on the vehicle and the user. If you charge your cell phone battery at home, you also pay the removal current and not what arrives in the cell phone battery. Understand the difference? In addition, the calibration requirements are so abstruse that it was actually largely impossible to convert the existing columns. An ensty technology must first be developed.

  10. sadly it is how it is
    And everyone once noticed that in a small scale that a charger and a battery will be warm. Since there is nothing for nothing in life, these are losses. The question is, of course, who loads with high performance, since I mean 50 or 100kW charging power, which unfortunately has a lot of loading losses. If the losses are 10% -20%, this should be due.

  11. I’m sorry, what?
    Sorry, but 20 % loss of loading because it "High -performance store" is, that’s nonsense. Around 5 to 10 % is more realistic and of course gruesome. The e-fanboys are happy to leave these load losses in their calculations. The fact is that the unequal charging stations are a cheek. Who thinks he has to charge for 80 cents per kw is also to blame.

  12. When…
    … 7 out of 10 tapped liters for "Synthousity heating" to be wasted by air & climate, but then I also guaranteed 10 liters of fuel through a calibrated measurement for my money. This is the topic and not the efficiency of combustion engines and what I do afterwards is my thing. I can also rub myself down or remove stains, as already written, that’s my thing!

  13. When…
    … you promise something, you should keep it – or not promise. On the 5th.1.10, 7:06 a.m., they had announced that they will no longer discuss my comments in the future, but only "read and [] enjoy yourself". After less than a week the first double violation: only reading didn’t work & you don’t sound deliciously amused either. The new year starts well.

  14. legal action
    Why does no consumer organization or the ADAC do legal action against the inactivity of the authorities? This inactivity is clearly politically motivated in order not to endanger the expansion of the charging infrastructure and thus e-mobility. But there is probably also the fear of standing against the left -green mainstream here.

  15. E mobility makes it possible
    If a weight at the weekly market is wrong or a small plastic cup is pulled along, the equity office tears off the construction and imposed punishments. Everything is possible with e mobility….No calibration, no clear statement about related electricity and more….Everything in the name of the climate and at the expense of our wallet
