Zašto Tesla nikada neće mijenjati baterije?

Among so many manufacturers of pure electric vehicles in the world, the "battery swap mode" seems to be the most popular among Chinese manufacturers. Even the national policy is tilting towards the power-swap model. Even in the subsidy policy in 2020, it is clearly pointed out that there is no subsidy for pure electric vehicles with a price of more than 300,000 yuan, except for models in the battery swap mode.

Štoviše, Ministarstvo industrije i informacijske tehnologije i Nacionalna uprava za energetiku također su počeli promovirati model zamjene baterija. NIO, Geely Automobile, Changan Automobile, CATL i dobavljači baterija također su počeli primjenjivati ​​zamjene baterija.

However, it seems that foreign car brands are not interested in the battery swap mode. Tesla, Mercedes-Benz, BMW, Audi's pure electric vehicles do not support battery swapping. So why doesn't Tesla think battery swapping is a good model?

To answer this question, we must first figure out why we "change the battery"!

【1】What are the benefits of changing batteries?

Jednostavno rečeno, mnoge su prednosti zamjene baterija. Prvo, radni vijek čistih električnih vozila može se produžiti zamjenom baterije. Drugo, može poboljšati stopu očuvanja čisto električnih vozila. Treće, također možete smanjiti cijenu modela kroz način zamjene baterije, a baterija se može iznajmiti umjesto kupiti. Četvrto, može povećati brzinu obnavljanja energije.

With so many benefits, why doesn't Tesla do battery swaps?

2 Why doesn't Tesla do battery swaps?

Why doesn't Tesla do battery swaps? To put it simply, Tesla's cars have achieved similar effects as battery swaps without supporting battery swaps. We will know the benefits of the power exchange mentioned above one by one.

Prvo, zamjena baterija može produžiti vijek trajanja baterije. Prema stručnim podacima, Tesla još uvijek ima oko 90 posto kapaciteta baterije svog električnog automobila nakon vožnje od 320,000 kilometara. Odnosno, stopa propadanja baterije malo utječe na većinu običnih potrošača. U Sjedinjenim Američkim Državama automobil se obično rashoduje nakon 320,000 kilometara, dok je broj pređenih kilometara u Europi 240,000 kilometara. Tesla kaže da su njezini paketi baterija dizajnirani da traju dulje od samog automobila, a do sada ni jednog korisnika nije utjecalo trajanje baterije, tako da potrošači možda nikada neće morati brinuti o kupnji električnog automobila i potrebi zamjene baterije Problem.

Second, battery swaps can improve the value preservation rate of pure electric vehicles. There are many factors that affect the value of a car. At present, in China's pure electric vehicle market, the highest value preservation rate is precisely Tesla, which cannot be replaced. Instead of Weilai, which can exchange electricity. why? To put it simply, the value retention rate depends on the brand, the amount of ownership, the quality of the model, the condition of the car, and the result of a comprehensive judgment. At present, whether in terms of brand or ownership, Tesla still has a great advantage. Therefore, the effect of power exchange on improving the preservation rate is not large.

Third, the price of the model is reduced through the battery swap mode, and the battery is rented instead of bought. This is also the way NIO used it for the first time. And Tesla's way seems simpler and more straightforward. It is to launch relatively cheap models such as model 3, and then through the manufacturing process, for example, the body-in-white of model Y uses an integrated die-casting rear bottom plate. The integration of 70 parts of the rear floor can be realized, and the traditional production process of welding the rear floor can be omitted, so that the production time and cost are greatly reduced.
