Description

Tesla held its annual “Battery Technology Day” event. Tesla CEO Musk previously stated that the products released by Tesla Battery Day will not be mass-produced until 2022.

Just before the “Battery Day” was held, Tesla CEO Musk hinted that the market should not overestimate the impact of “Battery Day” .

Release 4680 new battery, battery life increased by 16%, cost reduced by 14%

At this event, Tesla released a brand-new “4680” battery, which increased the cruising range by 16%, increased the energy density by 5 times , and increased the power by 6 times compared with tabs. The new battery can reduce the cost per kilowatt hour by 14 %.

This is a non-electrode battery designed by Tesla. It has a diameter of 48 mm and a height of 80 mm. The new “4680 battery” will take about a year to reach a capacity of 1 gigawatt, but Tesla is considering increasing it to 2 gigawatts per year.

Different from the domestic academic circles’ pursuit of all-solid-state batteries, it eliminates the tabs that generate a lot of heat, and solves the heat dissipation problem of high energy density. The length is 80mm, the energy density is increased by 5 times, and the power is increased by 6 times compared with tabs. Before that, Musk said on social media that all products on the battery day will be mass-produced by 2022.

Musk said that dry battery technology is not “stable and mature… it is difficult to expand production capacity madly”. It may take about one year for the experimental battery production at the Fremont plant on Battery Day to reach 10 gigawatt-hours, and full production will take three years. The goal is to rapidly increase battery production to 3000 GWh per year by 2030. It is about 85 times the capacity of the Nevada plant. Currently, Tesla is increasing the output of the trial battery production line at the Fremont plant.

Musk said that there are plans to halve battery costs. Plans to reduce battery costs include changing electrode materials and improving battery design and production integration processes. “We don’t have a car that can be easily afforded. This is something we will have in the future. So we must reduce battery costs.”

Develop a new electric vehicle of USD 25,000

Tesla announced that it will significantly reduce the cost of cells and battery packs. The new goal is to produce electric vehicles with a price of as low as 25,000 US dollars (about 170,000 yuan).

Musk said that the new battery cell production method and changes in the materials inside the battery cell will halve the price per kilowatt hour of Tesla battery packs, thereby reducing the price of electric vehicles to a level similar to that of fuel vehicles.

The price per kilowatt hour is currently the most commonly used unit for measuring battery pack capacity in electric vehicles. In the past 10 years, the price per kilowatt-hour has been declining continuously, from USD 1,100 in 2010 to USD 156 in 2019, a decrease of 87%.

Experts predict that the price of electric vehicles can drop to $100 per kilowatt hour by 2023, but Musk said that Tesla will start a three-year process to lower the price below this level. However, he did not specify the price target.

In the United States, the average price of electric vehicles has been declining. For example, it dropped from US$64,300 in 2018 to US$55,600 in 2019, a decrease of 13.4% in one year. This is largely due to Tesla’s Model 3. However, considering that the average price of a fuel vehicle is only $36,600, this price is still high.

Confident in three years to build a fully autonomous car

Musk said that in about three years, we are confident that we can make a very attractive fully autonomous car with a price of $25,000.

Musk also said that as of today, we recycle 100% of car batteries. By 2030, battery production will reach 3 trillion watt-hours. Tesla hopes to expand the power generation capacity of the super factory in Nevada, USA to 150 gigawatt-hours, which is currently 35 gigawatt-hours.

Musk said that by using raw silicon anodes, the price per kilowatt hour of the battery pack will be reduced by 37%. The company has obtained the right to mine a lithium-bearing soil in Nevada, USA.

The battery will be built directly into the structure of the car. This innovation is inspired by the fuel tank on the wing of the aircraft.

The structural battery will reduce the overall weight of the vehicle. This will reduce the total number of parts required (370 parts reduction) and speed up production. And most importantly, this will also reduce the cost per kilowatt hour by 7%.

Orders for over 600,000 electric pickups Cybertruck have been received

Tesla CEO Musk said at the 2020 Tesla shareholders meeting that he will release a test version of the fully automated driving system Autopilot in the next month or so. At the same time, Musk said that he expects the Shanghai plant to achieve the production target of 1 million vehicles per year. Our vision is to have our factories on every continent, which can guarantee the company’s liquidity and lead time.

Musk also said that he has received orders for more than 600,000 electric pickup Cybertruck, and sales are expected to reach 250,000 to 300,000 vehicles per year. In addition, he believes that in the long run, there will be no fuel energy vehicles. When asked whether Tesla would supply batteries to other automakers, Musk said that if Tesla can produce enough batteries for them, it will supply them.

In addition, Tesla said that Model S Plaid is accepting pre-orders at a price of $134,390. Tesla CEO Elon Musk said that with regard to the goal of producing $25,000 cars, Tesla’s current lowest-grade Model 3 starts at $37,990 in the United States, so it will drop by 34% in a few years.

Musk: Looking forward to the Shanghai plant’s production target of 1 million vehicles and 100% recycling of car batteries

Car deliveries this year will increase by 30%-40% year-on-year

Musk said at Tesla’s annual shareholder meeting and “Battery Day” conference that he expects Tesla’s vehicle deliveries this year to increase by 30% to 40% year-on-year.

Tesla delivered 367,500 vehicles last year, which means that this year’s deliveries will be between 477,75 and 514,500 vehicles. Previously, Tesla said that its car deliveries this year will reach 500,000.

Musk said that Tesla owners will conduct word-of-mouth marketing to potential car owners. He said: “In 2019, our delivery volume increased by 50%. I think that despite many very difficult situations, we will have a very good performance in 2020, and delivery volume may increase by 30% to 40%. There are too many difficult situations this year, such as pandemics and wildfires. In terms of production, there are also a lot of thorny problems. But due to the hard work of the Tesla team and many innovative methods to overcome the problems, We can still achieve significant growth in this very difficult situation. In fact, this may be the most difficult year since Tesla was founded.”

In addition, Musk also mentioned Tesla’s upcoming update to the autonomous driving system. The company’s promotion of this system is that it can provide car owners with the option of “self-driving” at a price of $8,000.
