The drive motor system is one of the core systems of new energy vehicles, which determines the main performance indicators of the vehicle such as climbing ability, acceleration ability, and maximum vehicle speed, mainly composed of a motor and its controller.
In the future, the construction and improvement of EV battery recycling system in china will also require the participation of multiple market players to work together and fulfill their responsibilities.
The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the characteristics of the battery's capacity, cycle and safety performance. The excellent performance of the separator plays an important role in improving the overall performance of the battery.
The electrolyte plays the role of electron conduction between the two stages of the battery, accounting for 5%-6% of the cost of the lithium battery, which generally is composed of high-purity organic solvents, electrolyte potassium salts and necessary additives.
In the industrialization path of ternary cathode materials ranges from NCM111, NCM523, NCM622 to NCM811, the trend of increasing nickel and reducing cobalt is obvious, where the current commercial application of NCM811 has matured.
The tire industry has absorbed vast demand for the increasing number of automobiles, whose half cost is occupied by the rubber. At present, the consumption of the domestic market is the biggest one with the self-sufficient rate of the nature of just 20%. To settle the problem of the unbalance between the supply and the demand, it is the chief method to increase the import of the natural rubber or t
Ultrafast lasers have unique ultra-short pulses and ultra-strong characteristics, which can focus on ultra-fine spatial regions and obtain high peak light intensity with low pulse energy. Unlike traditional long-pulse lasers and continuous lasers, ultrafast lasers have ultrashort laser pulses, which makes the spectral width of the laser pulses quite large, and also solves many processing problems t
The giants have been cultivating in this field for many years and have accumulated very rich technical experience. In the new energy tide, the air-conditioning system can be updated on the original technical plan because of less technical updates, smoothly shift its advantages. But in the field of battery thermal management, the industry is completely new with no leading manufacturers. For new comp
NdFeB magnet material is the third-generation rare earth material based on the intermetallic compound Nd2Fe14B, whose main components are rare earth elements iron, neodymium, and boron. Under the appropriate temperature, humidity and no strong external magnetic field, radiation and other factors that affect the magnetic performance, the magnet performance of the NdFeB will not be a large loss, whic
From early lead-acid batteries to nickel-chromium batteries then to lithium-ion batteries, there have been many iterations for battery technology. Compared with other types of batteries, lithium-ion batteries rely on their excellent comprehensive performance to quickly penetrate almost all downstream application markets.
Lithium batteries are a type of chemical batteries that rely on lithium ions to shuttle between positive and negative electrodes to achieve the purpose of charging and discharging. Due to their advantages of high energy density, high operating voltage, and long life, they have been widely used New energy vehicles, computers, and energy storage batteries.
Since Apple released the iPhone X unlocked with 3D structured light in 2017, 3D Sensing has finally entered our lives. Compared with the traditional camera, the 3D Sensing camera can obtain the depth information of the subject, that is, the three-dimensional position and size information, which is usually composed of multiple cameras + depth sensors. There are currently three mainstream technologie
Wind power generation is one of the most mature technologies, the most large-scale development conditions, and the best commercial development prospects in the field of renewable energy. The global wind energy is about 2.74×10^9MW, of which the available wind energy is 2×10^7MW. Under the existing wind power technology conditions, wind energy resources in China are sufficient to support more than
The database is a warehouse to organize, store, and manage data according to the data structure, an essential core technology for enterprise IT systems, which is listed as the world's three basic software technologies with middleware and operating systems.
Vitamin D3 is a nutrient necessary for normal calcification of bones in humans and animals, which is converted into an active form, 1,25-dihydroxyl, in order to play a physiological role, not directly working. It is widely used in feed additives, nutrition and health products, and medicine.
Plastic waste poses serious threats and challenges to the global ecological environment. Among the plastics currently discarded worldwide each year around the world, the most is plastic packaging, accounting for 36%, most of which are disposable plastics, thrown away after just one use.
On June 14, the last satellite of China Beidou-3 Global Satellite Navigation System was ready. The Long March 3B carrier rocket that had launched the launch mission has completed all the test work before launch and will be launched soon. Since then, the Beidou-3 navigation system will enter the era of global differential high-precision positioning due to this satellite, becoming the second global
