There are still many difficulties in achieving comprehensive indicators of power lithium batteries Recently, the 27th session of the Fourin World Automobile Research Association was held in Beijing. Wang Fang, chief expert of the China Automobile Technology Research Center, gave a keynote speech on the current status of Chinese and foreign power batteries. Suggestions are made for the development direction of China's power battery technology, and high -quality production capacity should be strengthened to re

There are many problems with electric vehicle battery power supply. If the charging takes too long, the journey is shorter. In addition, the battery is large and bulky, and the driver cannot speed up quickly, which is also dissatisfied. Researchers at the University of California Riverside Bernes Engineering have redesigned the composition of the battery, which not only environmentally friendly, but also solves the above problems. They believe that the adjustable nanoparticles that can be adjusted can develop en

What is the super capacitor? You can understand the supercapacitors as a small battery. Super capacitors are very simple. As long as the pointed voltage is not enough. As for the discharge of the super capacitor, the voltage is decreased, and the current is determined according to the load. That current is also declining. Super capacitors, also known as electrical chemical capacitors, dual -electric capacitors, golden capacitors, and Fara capacitors. It is an electrochemical element that developed from the 19

There is no doubt that the core component of the electric bus is the power battery, which directly affects the performance of the vehicle of the electric bus. People are satisfied or dissatisfied with the electric buses. How to use the service life, etc., what type of battery with electric bus is as attractive as today. Passenger car power battery: safety is more important than everything Safety should be the first essential of power batteries. The "ban" of the three yuan calm down the fanatic new e

At present, more and more joint venture brands have stepped up the field of new energy vehicles, including both the pure electric vehicle market with obvious current advantages of independent brands, but also covers the market with higher market acceptance and relatively weak independent brands. Essence Hybrid vehicles are more hopeful to replace traditional fuel vehicles. The independent brand cars should be based on this trend, find a direction, make up for the shortcomings, further improve the product line in th

New energy vehicle battery breakthrough "In the past year, the electric vehicle industry is transforming to high -quality development, and the situation is very happy." On January 7, on the eve of the forum on the China Electric Vehicle Hundred People Association, Chen Qingtai, the chairman of the Chinese Electric Vehicle Hundred People Association, accepted the 21st century. Economic Herald reporter said in an interview. The main manifestations of high -quality development and transformation are: p

At present, the mainstream technology route of electric vehicles is lithium ion battery and fuel power battery (PEMFC). Relatively speaking, lithium -ion batteries have obvious advantages in terms of technical maturity and cost, and have a higher degree of commercialization. The fuel power battery technology currently has a certain distance from large -scale applications in terms of cost, service life, and infrastructure supporting. However, compared with lithium -ion batteries, there is still an advantage of high

While the new energy vehicle continues to sell, the energy battery field has also flourished. Under the guidance of policy subsidies and market demand, power lithium batteries have begun to develop towards high energy density, while soft bag batteries have begun to embark on the stage of the market. Become the fragrant citron in the eyes of many car companies. From the perspective of the energy battery market, the soft bag batteries have recently become industry hotspots. Many car companies and battery suppliers

The reasonable selection of the welding method and process of the power lithium battery manufacturing process will directly affect the cost, quality, safety, and the consistency of the battery. Next, sort out the content of power lithium battery welding. 1 Laser welding principle Laser welding uses the excellent directionality and high power density of laser beam to work. Through the optical system, the laser beam is focused in a small area. Areas to melt the welding and form a solid welding joint and welded
