Site Drives the end of BMW and Co? New Tesla in the motorway test

Tesla successfully builds the Model 3 for the Chinese market in Shanghai – they are also exported to Germany. But now there are reports that the locally produced batteries of the Stromer should be significantly worse than the previous ones.

Around two months ago, Tesla in China launched a revised model 3 Standard Range+. The electric car from the Gigafactory Shanghai is equipped with a cobalt-free battery with lithium iron phosphate chemistry (LFP-Akku). Since the battery materials are cheaper than the cell chemia previously used by Tesla, the electric autopionier was even able to lower the prices for Model 3 in China.

As some users of the short messages of Twitter report, a cargo 3 from Shanghai has already reached the Belgian port of Zeebrugge in November. Since the German Tesla website also confirms that a large number of Model 3 "available for quick delivery" are the observations of the Twitter users.

Now, however, there are reports from China that are likely to miss a damper for the joy of revised Model 3: according to the Chinese electrical car portal D1EV.Com more and more users complain about insufficient reach and charging power for the new LFP batteries.

Problems with Teslas LFP batteries

According to this, several owners found problems with the LFP battery after receiving the electricity. The range is significantly restricted under winter conditions and the battery cannot be loaded 100 percent.

For example, a reader from Beijing reports that the Model 3 with the LFP battery has a range of 420 kilometers after the full loading process, but was only 5 percent load after a route of 214 kilometers. After the driver loaded 52 kWh for an hour, the display shows 420 kilometers again. According to his own statement, the owner uses his car for short -haul trips, park it in an underground car park at night and in a parking lot during the day.

customer "grew"

A Tesla dealer also admitted that one of his customers had become quite angry with him after buying one of the new Stromer with LFP battery. The buyer asked the dealer to exchange the vehicle and instead to get a model 3 with the old cell chemistry.

Like D1ev.COM continues, even this small number of experience reports currently many interested parties to search specifically for vehicles of type Model 3 Standard Range or Model 3 Long Range, which have been manufactured with the old cell chemistry.

The dissatisfactory performance of the new battery could be justified in a rapid shot on the part of Tesla: The development period for the previously used battery of the type 21700 was 23 months, while a former Tesla employee explains for the development of the LFP batteries less than twelve months who recently left the company. An internal source at the responsible battery producer Catl revealed that only nine months had passed from Tesla from Tesla from Tesla from the time of the announcement of the LFP battery. According to the internal source, vehicle tests and component tests were simply skipped. Another source even claims that Tesla in China would not even have a team for vehicle tests.

Customers should fully charge batteries as often as possible

Tesla had pointed out that the LFP batteries should be charged completely to 100 percent as possible-preferably once a week-. With almost all other electric cars, it is advised to charge the batteries too often to more than 80 percent charging level. An owner reports according to D1EV.Com also also that Tesla’s superchargers are now more crowded than before because apparently many owners actually try to load their car up to 100 percent charging, which takes significant time. The loading speed on the LFP batteries continues to decrease with increasing charging level, sometimes the vehicles could no longer be charged up to 100 percent, according to the reports.

So far, no safe and clear method has been known to recognize whether a Model 3 Standard Range vehicle is equipped with LFP batteries or the old cell chemistry. In some cases, at least the country of origin is on the bill, but this is not always the case. In addition, the LFP designs would have to have a higher empty weight than the previous standard range-plus version. The official empty weights of the vehicles also varied again and again in the past through equipment adjustments.

Site asked Tesla to comment on the reports. The answer is still pending.

  1. The batteries cannot be loaded to 100% ….
    lose capacity for unknown reasons. What’s next? The battery was in – … lose capacity for unknown reasons. What’s next? The battery was developed in just 12 months ready for series production in the article. There was even an opportunity for long -term and crash tests? How may the dendrites develop as soon as LI is involved, they are inevitable due to the system. I will hear new hearing very soon. I hope there are no people to harm. I have no trust in such a unstable battery. If only "because of unknown reasons" Should the KBA shake, withdraw the operating license, demand an 8-D report and only issue the operating license if it is ensured what the causes are and the proof is provided that these are finalized. This is how it goes normally in automotive

  2. Numbers Mr. Hutzler!
    The guarantees of the manufacturers, one gives 8 years and consistently 160000km, Hyundai 200000, Tesla 160000-240000, and fogying capapazity guarantees: VW, BMW, Skoda, Peugeot, Citroen, Fiat, Jaguar, Audi, Mercedes, Nissan, Honda, Porsche 70% Capacity, Kia 65%, Volvo 55%, some manufacturers do not provide information about the capacity guarantee. Even if a battery still has 80% capacity after 8 years, z.B. In the VW ID3 from 330 WLTP range only 264km, which is at approx. halve at 135km. 80% charge at 30 minutes, then result in a realistic range of 104km. The smaller battery packs will later be almost unsalable as used cars. Even a Tesla3 with 409km WLTP then only offers 160km range!

  3. @Pattern
    The tolerable loss of capacity of traction batteries in electric vehicles is controversial among users. Recently, the US non-profit organization Plug in America (PIA) examined the battery of the Tesla Roadster. The basis was a field test in which anonymous reports and data from more than 100 Tesla owners were evaluated.The result: the equivalent of 160.The Tesla battery still has a capacity of 80 to 85 percent.In addition, quick charging also plays a role in battery age. Because charging with high currents particularly takes the battery cells. As I said, I do not make my own claims, but use expert publications!

  4. @Hutzler
    And that means that there is still no reliable data over a lifespan of 8-10 years. If Teslafahrer raved about over 200,000km in three years, for my sake 7000km a year, this means that, in luck. If the exception is the exception in warm California, Germany looks different!

  5. The good Mr. Chowaniec…
    …and his Tesla beauty! You can of course ask at any price, but in the end it depends on how much money a used car goes over the counter and not to "File oak" In the offer. Besides, everyone knows that Teslakunde are almost freaks that overlook many defects with pain resistance. The used buyers will be similar, only with the difference that they.T. cannot pay horrendous new car prices for Tesla, it is similar with Porsche. The later teeth grappers with their tesla use pieces can of course no longer be heard. Nobody admits, a handle in the …. to have made. Drivers from Porsche, S-Class U have such problems.a. then rather not!

  6. @Chowaniec
    Yes and, what’s the accusation? The car is not just a battery! Have a look at Mobile de! From the year of construction 2008 down to 2000.Z. still offered around 209,000 burners. Example pleasant? Toyot Corolla Verso, built in 2006, 3.000.000km, Ford Site 2008/2.777.000km, Ford S-Max 2007 2.700.000km I could continue forever. There has long been the battery and thus total economic damage to the electric car. You can of course save yourself the money for new batteries and go on an adventure trip with the remaining capacity of the batteries, or invent the game of charging pillar hopping! Every free workshop awaits a burner with little effort into old age. With the electric car, the "Car doctor" just determine death!

  7. @Pattern linear high is a something
    naive approach. The dendrites will reach the other electrode over time, then the end of the day is. It is very difficult to predict when that is, depends on many factors. But with quick shops and a lot of acceleration, it is fixed, all thermal / mechanical stress also stresses the battery. Is like Russian roulette, who has a lot of burdens but several balls in the drum

  8. Cold batteries load more and more slowly
    I don’t understand what the problem is now. It is probably the poorly informed customer. In winter in the cold, the range decreases with every battery. It is the same with the charging speed. If it is cold, the battery is also cold and cannot be loaded as quickly as at warm temperatures. The LFP batteries can generally be slightly slower than the NCA batteries, but they have a lower degradation. The I3 (2018) from BMW has a range of 200km in summer, according to BMW. In winter with the heating switched on, it is only 90km. But no barrel is opened.

  9. @Santer is right, batteries are heated and cooled,
    If you get too warm/cold. the "Air conditioning" is at the expense of the range. The air conditioning has a certain time constant, d.H. When accelerating a strong acceleration or ride, the battery becomes very hot, the heat is slowly spreading. Due to different expansion there is mechanical stress.This can have evil consequences, in the simplest case loss of capacity, or battery beach

  10. Guarantee 160.000 km
    So the manufacturer’s guarantee of 160.000 km for the battery exceeds any manufacturer’s guarantee for combustion engineers. And that complicated combustion engines are already below 100.Can break 000 km, the full workshops (and also reports on the Internet) prove. Even the guarantee of hydrogen drives only goes up to 100.000 km according to the Toyota website. So you are already served with the manufacturer’s guarantee for the batteries. In addition, there are savings for oil, timing belt change and other service costs.

  11. Cheap battery ?
    How cheap is it ? All the tips would be too much for me. Load 20-80%. Not too cold, not too warm, 10 different charging cards, no Aldi for a free shop in the neighborhood….. Somehow everyone who suits the promise should simply gain their own experience and accordingly. I would even be willing to rent such a sum of such for 1 weekend. However, since I have no charging option at home, the topic is already done. And please do not provide any meaning on charging stations in the neighborhood. Garages have not been invented that you then put your property in the landscape somewhere !

  12. For Mr. Sochgen!
    For some time now, a certain guarantee standard for e-car batteries has been established across trademarks, which is eight years and 160.000 kilometers, depending on what occurs first. In addition to the new VW ID.3, Opel Corsa-E, Porsche Taycan, BWM i3, which initially only up to 100.Was covered with 000 kilometers. In addition, there are models such as the bestseller Renault Zoe, Nissan Leaf, Mazda MX-30, Jaguar I-Pace, Mercedes EQC, Polstar2, Seat Mii Electric, Skoda Citigo E IV, Ford Mustang Mach-E and Peugeot E-208. The manufacturers promise a minimum residual capacity for the battery, expressed in percent that should not be undercut. For the majority of the manufacturers, the minimum filling quantity is 70 percent, some also guarantee 65 or 75 percent.

  13. Small arithmetic task!
    What do manufacturers put on the battery? Yes right, 8 years of guarantee and mostly 70% capacity for the battery. Then we take the ID3 with an entry-level battery and 330km WLTP range, at 130km/h you can use the speed on the highway at 130km/h. 170km realistic range, there are enough tests for similar vehicles. 80% percent recharge after a stop 136km range. If the battery has only 70% capacity, there are only 119km realistic range, or. Conspirate 96km available to the chargingop. An 8-10 old golf petrol engine is fueled and continues to have its full range, while an e-VW becomes almost unsalable. This calculation example can of course be applied to further battery variant, but does not change anything in the later dilemma of the vehicles!

  14. @Sochgen you know better than that
    Manufacturer. The manufacturers are usually very optimistic, often rely on boundary conditions that can only be achieved under laboratory conditions, exactly according to the specified standard accordingly.
