The Development History of Lithium Battery Electric Vehicle

Lithium-ion battery electric vehicle has developed from its inception to today, and it certainly has the characteristics of its various technical development. What are the following aspects of its main performance?

First, traditional lead-acid batteries have become the Achilles 'heel of electric bicycles due to possible secondary pollution, large weight, slow charging speed, and short service life. The application technology of Chinese nickel-metal hydride battery has gradually matured, and once the safety problem of lithium battery is solved, it can also be popularized. Technology leading electric bicycle manufacturers should increase research on new energy sources, reduce the cost of new batteries, and give electric bicycles a stronger "source of life."

China has always been a world leader in the application of torque sensor technology and integrated circuit controller technology, and powerful enterprises are already applying integrated electronic and digital technology to such components as controllers, motor valve control and charging control. Intelligent electric bicycle will be the commanding point of future development.

Third, high-tech content of composite materials and high-strength light alloy materials will be more used in the manufacture of electric bicycles. While using aluminum alloy materials successfully, light and high-strength materials such as titanium alloy and Chromium Molybdenum steel were used, as well as carbon fiber and other polymer composites. Increase the strength of the electric bicycle and reduce the weight of the electric bicycle. It revolutionizes the performance and manufacturing process of bicycles.

Fourth, strengthen the research on charging technology, greatly improve charging efficiency, prolong battery use time. According to experts, 80 % of the batteries damaged in the market are filled with inferior chargers. High-tech companies in China have begun to study this area, changing conventional charging to variable pulse and digital control technology, effectively controlling the loss of water during charging, ensuring the balance of charging, and improving the battery's service life.

E-bike manufacturers cooperate with National research institutes and institutions of higher learning to systematically increase the scientific and technological content of products, form technologies and products with independent intellectual property rights, and continue to maintain a leading position in the technical field of electric bicycles in the world.

Fifth, speed up the application of new technologies and new materials in the world, and use nanomaterials in the production of tires, batteries and accessories to make electric bicycles lighter, faster and farther.

Seventh, strengthen the research of electric bicycle motor, develop and apply new energy efficient energy-saving motor, high efficiency compensation motor, further improve the energy use efficiency of electric bicycle.
