Describe Tesla battery cost and energy density

On March 22, 2017, Tesla senior executive KurtKelty had a speech of "Tesla's battery factory materials procurement and production” in international battery seminar. It has been a mystery on 2170 Tesla - Panasonic battery monomer cost and energy density asymmetry. As for Tesla breakthrough in this regard, international battery research and exhibition for the battery innovators awards will be awarded to the Tesla. What did KurtKelty speak at the conference? Let’s check together.

The first is their acceptance speech, Tesla Kelty representative to receive the trophy, and then he said, Tesla is a great pleasure for me to get this award.Then he told the room full of battery manufacturers and research expert, said: "everyone knows that we are not a company focused on the battery chemistry, that is not the reason why we won, the real reason was realized the commercialization of advanced technology of our success."

Then Kelty started the speech, the first topic is the value of data, Kelty said, so far, all the Tesla motors users use Tesla battery total power consumption has reached 7.5 GWh, how they use Tesla motors?To how much the intensity of charging and discharging?These data were recorded from the background back to the server, Tesla Tesla mastered a huge user database.Another is the Tesla energy wall and stationary energy storage systems, Kelty points out that using the total power consumption of the system is also on the market reached 300 MWH."I want to clear, these data can help us to optimize we have research and development for many years, Tesla motors and the energy transfer between the energy storage system technology."

When it comes to Tesla's vision, Kelty showed as CEOElonMusk tone: "we want to help you of electric vehicles, energy storage systems and solar power generation system suppliers, Tesla car parked in your garage, Tesla energy wall in charging for it, Tesla solar roof tiles in power at the same time, these can store electrical energy in the energy wall, the daily household or for car battery.You simply operating mobile phone can complete the whole process control, this is our vision of the future."In addition to the one-piece energy solutions designed for families, Kelty also discussed the deployment in Hawaii and California Powerpack Tesla enterprises energy storage system.He explained: "Powerpack has many application scenarios, we just begin to explore that had just begun to penetrate the market, market potential is huge."He explained, "Tesla's energy storage solution is a" one-stop shop ", it is a complete integrated system, make customers more easy to use.This is one of Tesla's product competitiveness.

The next, and finally said to the award-winning: Tesla - 2170 batteries, Panasonic Kelty points out that Tesla has grown into the world's largest battery enterprises, they are committed to continuously reduce the cost of battery and the secret of 2170 battery costs fell from vertical integration strategy of Tesla's battery factory.He pointed out that ElonMusk "first principles" thinking is through 2170 battery research and development process, this is a new battery energy density is highest at the same time, the root cause of the lowest cost.

The first principle of thinking about this, I want to talk about a bit, the so-called "first principles" thinking, that is, from the basic axioms and the hypothesis of self-evident to thinking problems, propose solutions, and resolutely put an end to think from the inference of other existing, which makes people tend to compare, and the principle of "first" thinking, comes from the way things are and the basic laws of physics, push forward step by step.

For example, Tesla was founded in the beginning, there is power battery experts point out that Tesla was unsustainable, reason is only one: the power battery costs up to $600 per kWh (currently Tesla's battery costs at $130 per kWh), but Musk question: "what is power battery raw materials?How much is the price of these materials in the corresponding market?How much is the manufacturing cost?If mass production, how much is the ideal power battery cost?"According to his calculations, the ultimate power battery costs can drop to $80 per kWh.

In the research and development and explain why18650 battery shape difference is not big, 2170 battery, Musk, said: "this is from two aspects of physical and economy according to the" first principles "thinking of thinking decision, this is our analysis of the thinking mode of everything, if there is no power battery in the world, that we how to design it?The design should meet the requirements of our final product properties, 18650 is not the most optimal design.

Under the guidance of this thinking mode, as shown in the figure below, Tesla's battery factory for raw materials also have in-depth layout of the battery.As Kelty said, this is a new battery energy density is highest at the same time, the root cause of the lowest cost.

Back to Kelty's speech, he went on to explain the Tesla cooperation with Panasonic: "our common development and optimization of the chemical characteristic of the cell size and shape, Panasonic in the field of power battery manufacturing ability is unique, they know how to make high quality products, high quality means that reasonable consistency, reliability, and low cost."Then he points out the differences in Tesla and Panasonic, which is made of the main causes of the two companies cooperation progress: "they have efficient manufacturing level and very conservative business strategy, and Tesla would layout is very forward-looking and crazy technology, the combination of the two companies is a very good complementary.

At the end of the speech, Kelty again expressed his confidence in the electric car market: "according to our internal forecast, the growth of the electric car market don't like our rivals in fossil fuel industry or research institutions predict so conservative, the market will soon usher in exponential growth."Currently Kelty and his team are still working to decrease the cost of battery, and more in-depth cooperation with supply chain partners at the same time, to prepare for the Model3 July start mass production.

So Kelty in Tesla and industry have won those grades?

In international battery research and fair website introduced this KurtKelty speaker column: scientists Tesla's battery, as the Tesla battery supply chain and senior director of business development, Tesla's headquarters in California PaloAlto as battery technology, senior director, is responsible with each single battery suppliers and raw materials developers, technical communication and business negotiation.Also led the team focused on evaluation of battery performance and reliability;In Nevada, Tesla's battery factory leadership partnership and battery material purchasing work;At the same time is also responsible for Tesla energy products sales in Japan.Before joining the Tesla, he founded and led the Panasonic battery research lab in silicon valley, and other batteries and fuel cells for Panasonic and the United States established a r&d alliance between developers.Orders, which owns 16 patents.

36 kr learned that more than 800 battery KurtKelty insiders listen to the lecture, including representatives from Chinese battery maker BYD, and outside the lecture hall of BMW i8 from the side reflect the value of this seminar.

Under the "first principles" , what do you think whether Tesla will reduce the battery costs to $80 per kWh?
