The development course of electric bicycle
Dec 27, 2018

For the development history of China's electric bicycle, the industry is generally recognized as three stages: the primary stage of electric bicycle, the initial stage of production scale, the stage of speeding development. The primary stage of electric bikes is also known as the early experimental production phase of electric bikes, in terms of time, from 1995 to 1999. This stage is mainly for the four parts of electric bicycle, motor, battery, charger and controller of the key technology groping research. In R & amp; D and production is mainly to produce enterprises spontaneous collection of information, tracking technology, organizational market observation, small batches of market trial delivery, but also so that electric bicycles began to enter the view of consumers, and they gradually recognized to accept. Technically speaking, the early electric bicycle, the new battery can only travel about 30 kilometers at a time, battery life is short, climbing ability is poor, easy to wear, and the motor is also brushed toothless motor.

But the accumulation of this period, for today's scale of industrialization in talent, technology and product development and other aspects of a good foundation. The second stage is known as the beginning of the production scale phase, is due to the emergence of several opportunities to promote electric bicycles during this time period, so that in the primary stage of the difficult electric bicycle suddenly ushered in the spring, but also the development of the industry into a scale, and the most valuable of these opportunities for the various cities of the "

Prohibition of friction "and" SARS "in the 2003 This time period is generally recognized as the period from 2000 to 2004, during which time, with the breakthrough in key technologies and the increasing performance of electric bikes, electric bikes became an alternative to motorcycles and bicycles, and it was fast, environmentally friendly, convenient and inexpensive, It also inspires the market's appeal for electric bikes. In the growing market demand, the rapid rise of previously R & amp; D and production enterprises, some new enterprises have also begun to enter, their investment in electric bicycles has been increasing, resulting in a rapid expansion of production capacity (see Schedule 1.1 for details). Moreover, the rapid jump in this period of enterprises are a big operation, has put those older generation of R & amp; D and production enterprises behind.

However, some well-known brands represented on the scale of enterprises have been formed, and in accordance with the north-south differences, but also formed in the industry in Wuxi, Zhejiang, Tianjin as the representative of the three major industrial agglomerations. The third stage is from 2005 to the present, this stage is China's electric bicycle overspeed development stage, by the industry dubbed "injection well stage." During this time period, with the fierce competition between enterprises greatly stimulated the progress of technology and the diffusion of new technologies, the technical level of the whole industry has been greatly improved, battery life and capacity increased by 35%, the motor from a single brushed tooth motor into a brushless high-efficiency motor as the mainstream, life increased by 5 times times, efficiency increased by nearly 30%, Climbing and load capacity increased by about 3.5 times times. While the performance is improving, the manufacturing cost is also greatly reduced, the price power drops to the original 21%, and in the controller system and charging system, the technical level is also greatly improved. Especially in the battery technology and motor technology have made great progress, electric vehicles dedicated lead-acid batteries in the technical breakthrough has been leading the international, but also formed to the sky, Super Wei as the leader of the Zhejiang Changxing Plate, Conrien, double-login as the representative of the Jiangsu Plate and Rida as the representative of the Guangdong Plate. Batteries also have a single lead-acid battery evolution of many types of high-performance batteries, and the emergence of lithium batteries, but also led to the development of electric bicycles, especially simple. In the motor, the invention of permanent magnet brushless motor, so that the pace of the development of the industry significantly accelerated. The key of motor performance is the performance of strong magnetic materials, the performance of rare earth permanent magnet materials is the most superior in all kinds of permanent magnet materials. China is recognized in the world as a large country of rare earth resources and rare earth products manufacturing power. Because of the good performance of rare earth strong magnetic materials, low price, strong manufacturing capacity, so that the international market expensive BLDC (brushless DC Permanent magnet motor) system in Chinese enterprises have been widely used, the electric bicycle industry has thus gained a unique resource advantage. In terms of total output sales in the industry, in 2005, the total production of various light electric vehicles (including electric bicycles) in hundreds of enterprises in the country is expected to have exceeded 9 million vehicles, exported about 200~300 million vehicles, to achieve 20 billion of industrial output, profits and taxes of about 6 billion yuan, related production and service areas of nearly 1 million people.

China's light electric vehicle production and sales have accounted for more than 90% of the world, China has become the world's largest producer, consumer and exporter of light electric vehicles.
