New energy vehicle super fast charging technology
In front of Xiao Bian, we briefly introduced the new technology products as the “legs and legs†of the car—the rice husk gray tires. Netizens are also opening their minds, but they also propose stone tires, noodle tires, and of course there are ashes. In addition to the car's "leg and leg" tires are constantly iteratively upgraded, as well as the power of the car device is also changing. Here we will talk about the car battery.
Tesla Super Battery Factory
Ironman Maske's Gigafactory Super Battery Factory was built by Tesla in partnership with Japan's Matsushita. Gigafactory is mainly used to produce lithium batteries on Tesla electric vehicles. According to Tesla's plan, by 2020, Gigafactory will produce batteries for 500,000 electric vehicles each year. Through Gigafactory's battery-scale production, the cost of the battery pack will be reduced by 30% compared to the current battery used by the Model S by 2017. The battery capacity of the upcoming Generation III battery pack will also increase, which is of great significance for Tesla's smooth development of the low-end model Blue Star. The main task of Tesla's battery factory is not to produce the most advanced batteries, but to use existing technologies and reduce costs through mass production.
Blue Star is the Tesla project's long-standing low-end model (recently renamed the Model III), which will be launched in 2017 with Generation III batteries. The model’s single charge cruising range is 200 miles and starts at $35,000. Compared to Model S, the starting price of 57,000 US dollars fell by nearly 40%. At the end of April this year, Tesla launched Powerwall, a domestic lithium battery system, and a large utility-scale battery, which received more than 40,000 orders in the first week of listing, and sales of about 800 million. Dollars.
Volkswagen Super Battery Life 300 km
At the end of June, the media revealed that the head of Volkswagen, Martin Wendun, revealed that Volkswagen is developing a "super-battery," and the new battery is cheaper and smaller. An electric version of the Volkswagen brand models is expected to reach 300 kilometers of pure electric range after being equipped with a super battery. "Compared to Volkswagen e-Golf, the new generation of Volkswagen electric vehicles will have twice the cruising range. Although 300 kilometers of cruising range still cannot be compared with the 265 mile of the Tesla Model S, the Volkswagen will launch more. Affordable electric vehicles, such as the next-generation e-Golf, are therefore more significant than the Model S in promoting the popularization of electric vehicles.
Volkswagen has said that it is developing next-generation lithium-ion battery cell technology that can achieve energy density as much as five times that of current batteries. To this end, Volkswagen's current focus may be mainly concentrated in two directions: 1. Novel solid-state battery technology; 2. Existing lithium-ion battery upgrade solution.
In November 2014, Martin Wendeng once said: "I think the potential of solid-state battery technology is huge. It is very likely that the application of this technology will increase the mileage of electric vehicles to 700 kilometers." It seems that Volkswagen should be more optimistic about the solid state. Battery prospects, but also shares in the development of solid-state battery company QuantumScape, shares 5%. Solid-state batteries have advantages over conventional lithium batteries in energy storage, and they also have the advantages of strong flame retardant capability and stronger safety performance.
Volkswagen may shift to a single lithium-ion battery cell design in the future. The goal is to reduce battery costs by 66% by simplifying cell design. A single battery design can take full advantage of VW's battery module assembly plant capacity, and even a single battery cell design can be used by different battery suppliers. At the moment, Volkswagen uses a variety of lithium-ion battery cells. For example, Panasonic supplies batteries for e-golf, golf GTE plug-in hybrids, and Audi A3 electric cars, while Samsung supplies batteries for the Passat GTE and other Audi electric cars.
Mercedes-Benz brand solar energy storage battery
Prior to this, Daimler has teamed up with The Mobility House AG and GETEC Energie AG to launch the first lithium battery cell "96-module ESS". The current total capacity has exceeded 500 kWh, and it will be upgraded to the next few weeks. 3000 kWh. Daimler called this solar energy storage battery, which is divided into domestic and commercial batteries, with capacities of 2.5 kWh and 5.9 kWh, respectively.
When used as a domestic battery, up to 8 battery modules can be combined to produce an "energy storage factory" with a capacity of up to 20 kWh; and when used as a commercial or industrial battery, the battery system can also be completely emit energy. Harald Kroeger, head of development at Mercedes-Benz, said that when the car travels millions of kilometers in high temperatures and cold conditions, the energy storage battery it uses can still work, so the battery can be used as a fixed storage. Can battery. Daimler's new energy storage battery will be produced by the ACCUmotive Kamenz plant in Saxony. ACCUmotive expects that the future production of energy storage batteries for automobiles will be increased and its application areas will be more extensive.
Since the battery is far from the internal combustion engine in terms of energy density, the cruising range has long been one of the biggest weaknesses of electric vehicles. In the new regulations promulgated by many countries, only the electric vehicle's single charge cruising range has reached a certain level in order to enjoy preferential subsidy policies.
