Pam na fydd Tesla Byth yn Cyfnewid Batri?

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.

Ar ben hynny, mae'r Weinyddiaeth Diwydiant a Thechnoleg Gwybodaeth a'r Weinyddiaeth Ynni Genedlaethol hefyd wedi dechrau hyrwyddo'r model cyfnewid batri. Mae NIO, Geely Automobile, Changan Automobile, CATL a chyflenwyr batri hefyd wedi dechrau defnyddio cyfnewidiadau batri.

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?

Yn syml, mae yna lawer o fanteision cyfnewid batri. Yn gyntaf, gellir ymestyn bywyd gwasanaeth cerbydau trydan pur trwy ailosod y batri. Yn ail, gall wella cyfradd cadw cerbydau trydan pur. Yn drydydd, gallwch hefyd leihau pris y model trwy'r modd cyfnewid batri, a gellir rhentu'r batri yn lle ei brynu. Yn bedwerydd, gall gynyddu cyflymder ailgyflenwi ynni.

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.

Yn gyntaf, gall cyfnewid batris ymestyn bywyd batri. Yn ôl data proffesiynol, mae gan Tesla tua 90 y cant o gapasiti batri ei gar trydan o hyd ar ôl gyrru 320,000 cilomedr. Hynny yw, nid yw cyfradd pydredd y batri yn cael fawr o effaith ar y rhan fwyaf o ddefnyddwyr cyffredin. Yn yr Unol Daleithiau, mae car fel arfer yn cael ei sgrapio ar ôl 320,000 cilomedr, tra bod nifer y cilomedrau sy'n cael eu sgrapio yn Ewrop yn 240,000 cilomedr. Dywed Tesla fod ei becynnau batri wedi'u cynllunio i bara'n hirach na'r car ei hun, a hyd yn hyn, nid yw bywyd batri wedi effeithio ar unrhyw ddefnyddwyr, felly efallai na fydd yn rhaid i ddefnyddwyr byth boeni am brynu car trydan a bod angen ailosod y batri Y broblem.

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.
