The battery renovations, the Tesla boss Elon Musk in the long-awaited "Battery Day" presented by the electric car maker, should enable significantly higher charging capacity in the next few years. A German battery expert is sure of this.

German carmakers still store many work steps in the development of electric cars to suppliers. Often only individual core components such as the engine are produced in your own house.With electric car pioneer Tesla, on the other hand, everything is done yourself if possible. This applies to both research, in which, according to battery expert Maximilian Fichtner, Germany does not have to hide, as well as to the production of electric cars, where the expert in Germany is currently still Hapert.

Fichtner is the director at the Helmholtz Institute Ulm, professor of solid-state chemistry at the University of Ulm and scientific director of the "Center for Electrochemical Energy Storage Ulm-Karlsruhe" (Celest), one of the largest research platforms in the battery range. His well -founded opinion is in the days after Teslas sensational "Battery Day" in great demand.

No other car manufacturer would dare to do new cell design on Tesla

In an interview, he summarizes the difference between the traditional car manufacturers and Tesla as follows compared to the German news portal Spiegel Online: "You try to build an electric car with proven methods that is equivalent to Tesla, only with better body gap dimensions. Tesla, on the other hand, reaches a lead through technology by dealing with the entire production chain, from integrating its own hardware and software to batteries to the finished car."

Now I have Tesla at the long -awaited "Battery Day" an unusual cell design presented that no other car maker would tackle this way. This is a new round cell in Tesla’s battery packs that work without a flag.

So far there are round cells in Tesla batteries in which "an rolled -up metal foil with a paste on it" is stuck that represents the actual memory material. At the end of the roll there is a small tab, over which the entire loading and discharge current flows along the winding. "Tesla has now managed to connect this role across and make the tabs unnecessary", Fichtner continues.

This in turn makes the way for the current much shorter and enables Tesla to increase the size of the cell-from the approximate size of a flashlight battery to the size of a beer can. "That would actually not make a manufacturer, otherwise the heat will not get out of the cell when it comes to quick charging", explains the battery expert. "Due to the design without a tab and the shorter paths, the resistance is lower, there is hardly any heat generated."

Tesla has the "Run screws in the right direction" turned

The new design changes everything: "The format alone makes 16 to 18 percent higher ranges possible, at the same time a system can be loaded up to six times faster. This is a quantum leap", Fichtner is sure.

Six times faster loading times and a massively increased range at cheaper prices: Even if Tesla misses the self -inserted brands of 54 percent more range and 56 percent lower costs by many percentage points and only achieves 30 or 40 percent more range and lower costs "a lot, based on an almost conventional battery chemistry.""Elon Musk has scheduled everywhere, from processing the raw materials to the finished car to make his cars better and cheaper", Fichtner is impressed. "Tesla apparently managed to turn both adjusting screws in the right direction. Even if the company only reaches a fraction of the announced growth, this is still well above what the competition is planning in this country."This article was written by Tobias Stahl

  1. Great
    Unfortunately there is still a lot missing to be great. The battery alone is not. It has to … Unfortunately there is still a lot missing to be great. The battery alone is not. There must also be an infrastructure that can also load the battery quickly. Exactly that will not exist so quickly because they z.B. also depends on the existing infrastructure. By the way, these batteries have not yet been tested. First of all, there are only large -gauge announcements.

    The formulation of E-Auto Hasser actually shows that it is not worth it at all to answer such a spelling! How can you hate a dead object as if it were an evil person, but everyone has their own, albeit strange worldview. Everything else that you make of yourself suggests that you also believe that next year the first flight to Mars is coming up!

  3. A very bad day
    For the E-Auto Hasser. If there are soon the new batteries that will also create 800 km. Which can be loaded as quickly as normal refueling plus toilets gang or plus coffee, which one or the other person does after 800 km. If the price is also cheaper than with these old cars with an explosion engine, I’m really looking forward to the excuses. They are faster, quiet, they do not stink, they do not need inspection, are tax -free, you can recharge your batteries for free while shopping (load). If all car manufacturers now build battery factories, the waiting times of one year will surely shorten soon. If someone had told me that 10 years ago that you drive with an electric car with 230 km/h, tanks for free for 500km when shopping, the answer, "crazy" !

    Faster for 10 minutes. Leiser only at low speed because with many vehicles the rolling noise of the tires makes the most noise. Instead of inspection and tax by half more expensive with a shorter lifetime. If all car manufacturers build batteries, they would pound themselves for raw materials instead of the batteries.

  5. No matter where, you meet Hutzler!
    Your theories do not correspond to the real facts! Tesla did not make a profit in 2019 with sales at list prices, these come from sales of environmental certificates, so it can be described as a kind of trickery!Porsche earned an average of € 16305 on each car, profits with which it is easy to develop a Taycan in good quality and to bring it onto the market.To date, Tesla has not managed to sell vehicles that of a quality of Porsche, BMW U.A. even nearly corresponds. The current global profitable sales of burning guarantee the income that manufacturers need to gradually switch their vehicle range to alternative drives.Tesla does not have this money and that will be the difference in the future.

  6. Mr. Arndt,
    The Free Cash Flow from Tesla is currently $ 398 million. The Free Cash Flow of VW is around 20 billion euros. How was it the same with the blind?

  7. the unthinkable think
    Tesla did something that is unthinkable here again. Such innovations are of course more difficult to implement here in the established structures than with a company that has a fixed goal in mind: "The acceleration of the transition to sustainable energy". This company goal alone is a novelty, because other companies have only one goal in mind: maximization of profits. This goal is primarily pursued here. Therefore, new ideas are in short supply. But if everything else is subordinate to the Tesla goal, it is only logical that the ideas in the company are in the direction "Transition to sustainable energy" just bubble. One can look forward to the future with this company – in spite of all the non -skial callers.

  8. I just read
    Tesla announces. They have already announced a lot! The focus is no longer on the range alone. It is now about using less resources to become easier and more compact. Everything else is just a question of the battery size and prices for it! They do not drop through demand but through the expensive material used!

  9. Next hymn of praise
    On Tesla. Tesla and only Tesla can judge everything. Every 2 day an innovation regardless of whether it can be implemented or not. From the idea to production in no time; Just how to not really ready for series production and tested at Tesla. All other manufacturers are "Idiot" and non -known.

  10. Sensational !
    Then only the implementation into series production is missing. However, it is difficult to imagine one. The whole industrial world including. The battery and battery manufacturer researches the battery topic and does not get any further. Everything is waiting for a car manufacturer to get the curve. One should also not forget one thing: you might think that the entire car world must now switch to battery. If you look at the world map, there are still quite a few battery-free areas…..

  11. Nice to hear something
    From our battery goals, be it Ulm or Munster, the latter got 500 million tax money because they are the best. You hear zero and nothing from them, only that Tesla may bring something back on the market soon, maybe soon. Perhaps they are in the secret research that Tesla is amazed in 2 years of building blocks when they see our new battery, or they don’t get anything in line.

  12. When the battery researchers…
    Would be successful, then it would be very good. Then the German manufacturers could still conquer the market. Tesla does not have to remain the market leader. His company goal, the promotion of renovation to sustainable energy has already been achieved.

  13. So soon
    become e-cars much cheaper and drive much further and load much faster. Then why should I buy such a car now? And when I want to change, an old e-mobile with old battery technology is practically only to be given away?! With the announcement, Musk could have shot an enormous own goal. This is practically harmful to business, the share has fallen by more than 10% since these announcements.
