TSLA features in battery pack research and development -Lithium - Ion Battery Equipment
With the two-year fire of lithium-ion batteries and new energy vehicles, and the recent small disaster in the stock market, the lithium-ion battery sector has gradually climbed out of the quagmire and has attracted the attention of the market. As new energy vehicles are relatively complex, there are many standards, and prices are classified and compared in detail, the author, as a former electronics and electrical professional technician, makes our knowledge simple and effective in terms of lithium-ion batteries, which is simple and easy understood, without further research. The leader in new energy vehicles is Tesla. Technology and the market are the leaders. Therefore, learning from Tesla is the first step in learning from the new energy field. The understanding of lithium-ion batteries also begins with the lithium-ion batteries of Tesla cars. Aside from the electric motor technology, the Tesla also performs as well as a conventional gasoline-powered car, thanks to its advanced battery technology. As one of the core technologies of electric vehicles, what are the characteristics of Tesla's battery pack development?(Lithium - Ion Battery Equipment)
Here's the battery pack used in Tesla cars: it's the sealed exterior, 900kg, almost half the car's mass, and the battery is undoubtedly the heart of it. Check this out: It turns out to be a regular 18650 Li-Ion battery, a regular Li-Ion battery for laptops and power banks. Tesla models have at least 7,104 18650 lithium-ion cells that make up the battery pack. Of course, the actual structure is more complex, and many problems such as connection, heat dissipation, and explosion-proof need to be solved. What is this damn 18650 Li-Ion battery? Read on.
18650: Indicates that the battery is 18mm in diameter and 65mm in length. A typical AA battery is 14500, 14mm in diameter and 50mm in length. Generally, 18650 lithium-ion batteries are used more in industry and less in civilian use. They are also mostly used in notebook batteries and high-end flashlights. In other words: 18650 is the size of the battery, which can be divided into lithium ion 18650 (most common), lithium iron phosphate 18650 (second), and nickel hydrogen 18650 (least) according to the type of battery.
Now, 18650 Li-ion battery is almost clear, what is the benefit of this mode? First, it must use Lithium (Li) as an important material, and Li-ion battery is light in weight, large in capacity, and has no memory effect (mobile phone Ni-MH battery A decade ago, the eighties should have impressed), the widespread use of digital devices was powered by lithium-ion batteries. The biggest advantage of lithium-ion batteries is high energy density, 1.5 to 2 times the capacity of nickel-metal hydride batteries of the same weight, and a very low self-discharge rate. In addition, lithium-ion batteries have almost no memory effect and no toxic substances, which is also an important reason for the widespread use of lithium-ion batteries. Another plus: the 18650 lithium-ion battery can theoretically be recharged 800 times. According to Tesla's standard version, the theory is that the battery is charged at 370 kilometers. In fact, taking into account battery loss and temperature, 300 kilometers is appropriate. The author drives 50 kilometers every day, and takes his family to play on weekends and holidays, about 100 kilometers. All year round, 400 kilometers per week, 20,000 kilometers per year, the battery pack can be used for 8 years.
To make a simple summary: 18650 lithium-ion battery has the characteristics of large capacity and long life. As the first lithium-ion battery, 18650 battery is currently the most mature and stable battery combination in the world, still occupying a leading position, and our country Of the billions of years to produce 18,650 batteries, this figure is more than any other material. New energy vehicles are powered by 18650 batteries, which is the best choice at this stage. Therefore, if you want to invest in stocks in the new energy vehicle industry, you can start with the core battery pack, learn the relevant knowledge of 18650, and then transfer to the subdivisions such as complete vehicles and motors.
