Tesla (TSLA) - Tópico principal

so falta o que interessa

E o que é?

Tesla -40% since Elon had funding secured to go private at $420

Aposto que ele vai ser o ultimo a rir.
Como dizia o outro, "Deixa-os pousar..."

Tesla vai anunciar fábrica europeia. Em Portugal?

Depois da China, a Tesla vai instalar uma Gigafactory na Europa. O local ainda está no segredo dos deuses, mas vai ser anunciado em breve. Portugal está na corrida, mas pode já não estar na liderança…

Resolver o problema de carregamento nos EV's, a grande velocidade 

Electrify America says it will bring chargers online soon that
give cars 20 miles of range per minute of charge time,
up from 9 miles a minute for a DC fast charger.
The energy throughput on those will be so intense that the
company has had to design a new cable with built-in cooling;
otherwise, the copper wire would need to be as thick as a fist,
company engineers say.

Então mais de 15 anos...(em média)

Se fizeres em media 54.000 km por ano dá isso sim...
Se poupares em combustivel uma media de 4 euros por 100km poupas 35.000 euros.
Deve dar para comprar uma nova ( ou um carro novo)

E se o combustível baixar?

Continuas a poluir. 

Continuas a ir ás oficinas, eles agradecem

Tesla Gigafactory 3 obtains official govt certificate in record time ahead of production

Tesla has obtained an official government certificate of approval for Gigafactory 3 in record time ahead of the start of production, which is supposed to be imminent.

 
Gigafactory 3 is Tesla’s first manufacturing facility in China and it’s also the first electric vehicle factory wholly-owned by a foreign automaker in the country.

As the trade war between China and the US keeps getting more complicated, it’s becoming more important than ever for Tesla to have manufacturing capacity in China.

They will be able to avoid increasingly uncertain import tariffs in the biggest auto market in the world.

They have been moving extremely fast to get Gigafactory 3 ready.

O jornalismo anda de rastos - ou erro é de prepósito para atrair trafego e comentários - e a leitura também...

Uma coisa é uma "pilha" capaz de aguentar ciclos de carregamentos/descarregamento antes de dar o berro, outra O QUE O TÍTULO E A PRÓPRIA "NOTÍCIA" INSINUAM...

Tens sempre a noticia em Ingles

Destaco isto da noticia, que é FANTASTICO:
We are talking about battery cells that last two to three times longer than Tesla’s current battery cells.

They have tested the battery cells under different conditions and cycles. Even at the extreme temperature of 40’C, these cells were lasting 4,000 cycles.

With an active cooling system, like in Tesla’s battery pack, it was pushing the battery cells to over 6,000 cycles, which would easily mean over 1 million miles in a good battery pack.

Tesla’s battery research partner has released a new paper on a battery cell that could last over 1 million miles, which they say is going to be particularly useful in ‘robot taxis’ — something that Tesla wants to bring to market.

 
When talking about the economics of Tesla’s future fleet of robotaxis at the Tesla Autonomy Event, Tesla CEO Elon Musk emphasized that the vehicles need to be durable in order for the economics to work:

The cars currently built are all designed for a million miles of operation. The drive unit is design, tested, and validated for 1 million miles of operation.

But the CEO admitted that the battery packs are not built to last 1 million miles.

Earlier this year, Musk said that they built Model 3 to last as long as a commercial truck, a million miles, and the battery modules should last between 300,000 miles and 500,000 miles.

However, the CEO claims that Tesla has a new battery coming up next year that will last a million miles.

Jeff Dahn and his lab, who are doing battery research for Tesla, have released test results for an impressive new battery cell that is going to be Tesla’s new million-mile battery, according to a source familiar with the matter.

The new battery tested is a Li-Ion battery cell with a next-generation “single crystal” NMC cathode and a new advanced electrolyte.

Dahn’s team have been extensively testing these cells and based on the results, they think that the battery could power an electric car “for over 1.6 million kilometers [1 million miles].”

Here’s how Dahn’s team describes the results:

We present a wide range of testing results on an excellent moderate-energy-density, lithium-ion pouch cell chemistry to serve as benchmarks for academics and companies developing advanced lithium-ion and other ‘beyond lithium-ion’ cell chemistries to (hopefully) exceed. These results are far superior to those that have been used by researchers modeling cell-failure mechanisms, and as such, these results are more representative of modern Li-ion cells and should be adopted by modelers. Up to three years of testing have been completed for some of the tests. Tests include long-term charge-discharge cycling at 20, 40, and 55°C, long-term storage at 20, 40, and 55°C, and high precision coulometry at 40°C. Several different electrolytes are considered in this LiNi0.5Mn0.3Co0.2O2/graphite chemistry, including those that can promote fast charging. The reasons for cell performance degradation and impedance growth are examined using several methods. We conclude that cells of this type should be able to power an electric vehicle for over 1.6 million kilometers (1 million miles) and last at least two decades in grid energy storage.

Para calar os profetas da desgraça 

Tesla EPS beats by $2.14, misses on revenue
Oct. 23, 2019 4:56 PM ET|About: Tesla, Inc. (TSLA)|By: Mohit Manghnani, SA News Editor
Tesla (NASDAQ:TSLA): Q3 Non-GAAP EPS of $1.91 beats by $2.14; GAAP EPS of $0.80 beats by $2.17.

Revenue of $6.3B (-7.6% Y/Y) misses by $180M.

Shares +9.8%.

Foram incríveis os resultados, ainda queria comprar abaixo dos 190$ mas parece que a oportunidade já passou, por outro lado se conseguem fazer dinheiro a vender model 3 vai ser brutal quando tiverem o ride sharing, podem escalar a produção e começar já com nova fábrica na europa
