Volkswagen is firmly committed to the transformation to the field of electric travel. The Volkswagen brand released the "ELECTRIC FORALL" plan, which strongly promoted the breakthrough development of global electric vehicles. MEB modular electric drive platform is an important part of the Volkswagen brand electric vehicle offensive, which is specially designed for electric vehicles. Volkswagen Brand ID It will become the world's first model produced based on MEB platform; It will start production in Z

There are more and more owners of new energy vehicles. While enjoying the convenient, intelligent and environment-friendly travel experience that new energy vehicles bring us, many car owners pay more attention to the protection of their cars, especially the service life of their batteries. After all, for new energy electric vehicles, the battery is a very important accessory, and the battery life determines the service life of electric vehicles. However, in terms of protecting electric vehicles and trams, there ar

The first Beijing Future Science City Hydrogen and Fuel Cell Technology Development Conference, hosted by the Beijing Future Science City Hydrogen Technology Collaborative Innovation Platform and hosted by the Beijing Science and Technology Cooperation Center, was recently held in Beijing Future Science City. With the theme of strengthening collaborative innovation and promoting the autonomous development of domestic hydrogen energy and fuel cell technologies, the conference focused on the core key technologies of

The existing commercial battery technologies include lithium ion battery, lead acid battery, nickel hydrogen/cadmium battery, sodium sulfur/nickel battery, etc. These battery technologies are mature and have been widely used in electric vehicles, mobile phones, laptops, wind farm energy storage systems, grid frequency modulation, distributed power supply, microgrid and other fields. Energy storage was rated by Davos Economic Forum as one of the top ten new technologies that may change the world in the future. En

According to foreign media reports, researchers at Shinshu University in Nagano in Japan are developing a thin, high-capacity lithium-ion battery, which may open a new research field of electric vehicle energy storage system. Lithium ion battery can store a large amount of electric energy, but its storage capacity will decline with the extension of service time. In order to deal with this problem, Zettsu and his colleagues examined the electrical and electrochemical properties of the high-voltage (>4.8V, vsLi

At present, it is mainly affected by government subsidies. If there is no subsidy, there will be great opportunities for lithium iron phosphate in the passenger car market in the future. As the time of subsidy recession gradually shortens, there may be more and more opportunities for lithium iron phosphate in the passenger car market. Recently, the ninth batch of Catalogue of Recommended Models for the Promotion and Application of New Energy Vehicles released that Jiangxi Antchi New Energy Technology Co., Ltd

According to foreign media, researchers at the University of Waterloo have developed a new type of fuel cell, which can increase the endurance of electric vehicles by 10 times compared with the current battery technology. If large-scale production can be achieved, the cost will not be too high, which can provide power for cars. Xianguo Li, director of the University's Fuel Cell and Green Energy Lab, said: "According to our design method, the cost of new fuel cells may be equivalent to or even lower than

It is reported that American researchers are developing a new freezing method recently, which can prolong the life of lithium batteries and is safe and flexible. In the future, the "frozen" lithium battery will also be used in smartphones and tablets. According to the Daily Mail on April 24, American researchers have developed a new freezing method, which can extend the life of lithium batteries, improve safety, and the batteries can also be bent. This technology may be applied to smartphones and table

Recently, researchers from Tokyo University of Technology and other institutions in Japan have recently developed all solid state batteries that can be charged and discharged at super high speed, taking a big step towards the practical application of all solid state batteries. All solid state lithium battery is a new type of battery using solid electrodes and solid electrolytes. Its high density, high safety, high output power and other properties are more advantageous than traditional liquid batteries. It has a
