Tesla builds cars, builds batteries?

Tesla’s self-developed battery has new movements and advances. Tesla is building a battery production line in Fremont, USA, and plans to use its own equipment to make batteries, which means Tesla’s self-developed batteries are finally coming out, According to Electrek.

Don’t know if you remember? In June 2019, Tesla’s secret lab on Kato Road, called the “skunkworks lab”, was revealed as the site of Tesla’s battery design and research into its production process.

The lab is in Fremont, just minutes from the Tesla plant. Yes, it’s all such a coincidence.

Tesla Battery

Tesla’s ambition to self-develop batteries is really starting to “expose” last year.

Pull the time back a year ago. In February 2019, Tesla announced the acquisition of Maxwell.

What does this company do? In layman’s terms, it is the research of battery technology, its dry electrode technology can increase the energy density of the core to more than 300Wh/kg, the future may further increase to 500Wh/kg. Maxwell, meanwhile, says its battery still has 90 percent capacity after 1,500 cycles of charge and discharge.

To be clear, its technology can optimize battery performance, which in turn significantly improves the range of electric vehicles. The acquisition of such a company has led to constant suspicion.

Now when we open Maxwell’s website, it’s Tesla-related posters that are in the spotlight. Musk, as CEO, said of Maxwell’s battery technology: “We think this is a strategic technology that will have a huge impact on the cost and scale of battery production — both to reduce costs and reduce the amount of money needed for large-scale production.” “

Also in February 2019, the Tesla Battery Research Group, led by battery expert Jeff Dahn, filed a patent for a new battery chemistry that could provide faster charging speeds, longer life and lower costs for batteries. The technology can be used not only for energy storage, but also in electric cars.

These two things are superimposed together, so that people start to think about.

And at the next shareholder meeting in June 2019, when the stylish Tesla CTO JB Straubel talks about “large-scale solutions for battery production,” he uses the word “battery cell production” rather than “battery production.” 。 Drew Baglino, Tesla’s vice president of technology, said it wanted to be “master of its own destiny”. It also said it had “learned a lot from partners” and that there was now a “solution.”

The implication is already clear that Tesla is trying to make its own cores and be its own masters. For a long time, Tesla and battery partner Panasonic’s “love” has long been known.

But Tesla’s pace hasn’t stopped, and from battery design to manufacturing, Musk wants to take full control. In October 2019, Tesla acquired HIBAR SYSTEM LIMITED, a company known for its precision metering pumps, fluid injection systems and battery manufacturing systems.

For more than 40 years, Hibar has been the preferred supplier of first-time and secondary battery lines in the battery industry. By acquiring the company, Tesla would also be able to “call the Dragon (to make its own battery)” by filling in the most basic manufacturing capacity.

Life million miles

So, the question is, what about the performance of Tesla’s battery? This is the topic of greatest concern to all.

At Tesla Autopilot Day last April, self-developed self-driving chips finally came to the fore. Meanwhile, in talking about his ambitious “ROBOTAXI” plan, Musk announced that Tesla would build a “million-mile” battery as early as next year (2020). Here’s a comparison: The Model 3’s drive and body design is a bit like a commercial truck, with a design life of up to a million miles, but the battery pack ‘only’ 300,000 to 500,000 miles (1,500 charge-discharge cycles), which means Tesla wants to create a battery that matches the life of the vehicle.

Of course, Musk isn’t a mouthful. Remember the earlier battery team led by Jeff Dahn? In September 2019, Dane Labs released a paper describing how to make Musk’s dream battery.

Dahn writes in his paper:

We’s conclude it cells of this type type be able to power an electric vehicle for over 1.6 million-for-kn-kn-kn-chis (1 million miles) and last at the least siens in grid energy storage.

We have come to the conclusion that the battery can last more than 1.6 million km and can be used in energy storage units for 20 years.

In December 2019, Tesla officially acquired the patent through Tesla Motors Canada.

Next, let’s go back to the latest news from these two days: Tesla has built such a pilot battery production line in Fremont, and “million-mile-long self-study batteries are coming online.”

Add another interesting point: Tesla’s battery patent is for NCM (the battery positive material is nickel-cobalt manganese), and now Tesla uses the NCA (Nickel Cobalt Aluminum) core. However, Tesla’s two new battery partners, Ninder Times and LG Chemical, use both NCM batteries, so the next Tesla big chance will turn to the NCM.

Coming soon

According to the information released so far, Tesla has integrated the technology and resources of several of the companies it acquired, and the self-researching core is ready, and once the trial goes well, the Tesla-branded battery will be officially launched.

Previously, we’ve written an article that takes stock of Tesla and Panasonic’s past. From the beginning of the gold partner to the current tension, really booed. And now, in addition to Panasonic, Tesla has the Ninder era and LG Chemical.

But putting the battery so important under control is absolutely unacceptable for the controlling Musk, who has been “furious” on Twitter since Panasonic’s limited battery capacity has affected Tesla’s capacity climb; plus new products that are in high demand for batteries (such as Semi, next generation) Roadster, Cybertruck, etc.), Tesla needs to increase battery capacity while reducing costs …

It is imperative to realize self-production for batteries.

Musk said at last year’s shareholder meeting:

investors to look out for two things in the coming year: battery availandand and the forgos in full self-driving.

Over the next year, investors should focus on two things: battery availability and advances in self-driving technology.

This actually implies a self-study of batteries. In terms of self-driving, Tesla has dug a hole in the “Million Robotaxi on the Road” and it’s time to look at further information about Tesla’s batteries.

The answer may be revealed at Tesla Battery Day in April.

Hopefully, Musk will be able to translate to us, what is it called a surprise.
