Which is the strongest electric vehicle battery technology?
With the continuous deepening of the strategy of new energy vehicles, pure electric vehicles have become the focus of the current industry. However, with regard to the maturity of electric vehicle technology, the industry has a lot of controversy, and the technical routes of various brand manufacturers are also different. They need to be able to store electricity safely and reliably, and at the same time make it affordable for consumers. Pure electric technology in the end is reliable, and listen to Kai Chen morning wind to interpret the most important core technology of electric vehicles - battery technology. Battery Technology Contest Energy conservation and environmental protection, and the country's continued policy subsidies are favorable, and now the major car companies are playing the idea of ​​new energy vehicles. In addition to high-profile Tesla in China, BMW, Kai Chen, BYD, and Beijing Automotive have all introduced pure-electric models. However, although they are all electric vehicles, the most important battery technologies are not the same. As we all know, the quality of the battery determines the life of the electric vehicle, energy consumption, durability and other issues, and in addition to the above quality problems, the cost can also be affordable to ordinary consumers. So, in this number of indicators, who's battery technology is stronger? In fact, limited by the cost pressure after mass production, the BMW i3 with a starting price of 449,800 yuan and the luxury electric vehicle with a price of 1 million Tesla are not available to the general public. High battery costs have become a key factor. Tesla uses a 18650 lithium cobalt oxide battery, which has high power, high energy density, and high consistency. However, the safety factor is relatively low and the cost is relatively high. Therefore, it is not widely used by other manufacturers. However, in the market, there are still fast-growing new energy vehicle brands sought after by the market, in the current market, the more mature models, for example, BYD is using its own battery technology lithium iron phosphate battery, it has a good battery performance and Stability, but in the low temperature environment, lithium iron phosphate battery performance loss, conductivity may be affected. The Qi Chen Morrison, which was launched in September this year, has a price range between 267,800 and 2,818,800 yuan. The actual price after enjoying the subsidy was between RMB 172,800 and RMB 168,800. The price was lower than that of a pure electric vehicle at the same level. BYD e6 and BAIC Bao EV electric vehicles have certain competitiveness in China. The battery technology used is the lithium-manganate battery most widely used on the market today. This battery pack consists of 192 battery cells, with a total weight of less than 200 kilograms, with an ultra-high strength steel plate of 1400 megapascals outside. The parcel is installed in the middle of the chassis of the vehicle and firmly holds the center of gravity of the vehicle. Nissan Lithium Battery Technology Can Stand the Test In fact, Qichen Morrison's high quality and low price can benefit from Nissan's mature lithium battery technology support. With the world's attention to energy conservation and environmental protection, Dongfeng Nissan Group has launched its first pure-electric morning breezes to the Chinese market through the Qichen platform. This car is based on the Nissan Leaf's localization research and development, is currently the leader of the domestic pure electric market. The Qichen Morrowind and Nissan Pinnacle come from the same Nissan exclusive EV platform, which is currently the world's best-selling zero-emission electric vehicle. As of November, Nissan Leaf has reached 58% of the world's electric vehicle market. So far, it has sold 200,000 vehicles worldwide and is derived from Nissan’s advanced pure electric vehicle technology. As a brand-new automotive category, “safety†is undoubtedly the first pass for new energy vehicles. In this regard, Ye Lei, full-time deputy head of the Dongfeng Nissan Market Sales Headquarters, said that if a car is opened on March 7th, 30% is safe. Sexuality, 70% is functional, then in the research and development process of Kai Chen Morrison, Dongfeng Nissan focuses on 30% safety with a force of 70%. Laminated battery design guarantees the safety of the battery body while ensuring heat dissipation. As for the insulation problems during charging and maintenance, Ye Lei said: “We have done a variety of destructive tests, such as directly watering the charging port, or even soaking the battery module in water 12 meters deep, while charging There is no problem." It is reported that Kai Chen took the lead in the industry to launch "e enjoy worry-free", the service covers the worry-free car, worry-free charging, worry-free travel, enjoy worry free service sector. “Qichen provided 6 months/10000 km maintenance, 5 year/100,000 km warranty policy, and provided 5 years worth of repurchase service.†Lei said: “'e enjoy worry' is to think what customers want Worrying customers will allow more consumers to accept pure electric vehicles."
Nozzle Cap is also called filter cap, drain cap, water cap, and backwash filter. It is used in the filter water distribution system and filter.
The stainless steel nozzle cap is a perfect replacement of the traditional plastic water cap in water treatment equipment. Our nozzle cap is a new generation of products in the water treatment equipment industry. The stainless steel nozzle cap enjoys the advantages of large circulation area (about 2-3 times of the same size plastic slot cap), long service life, safe and reliable, low comprehensive cost.
