Tsinghua University Magui long, 20 electric bicycles for many years for the technology, the industry as “the first person of Chinese electric car.” Professor Ma Guilong industry first technologies inventions laid the foundation and management, and free to contribute their own patents, and use their findings to guide the industry in technological development.

Record of interview:
Course on technical research
Reporter: Are you in the electric bicycle industry is a veteran of the technology, can be introduced to the history of your technology?
Malaysia: Domestic electric cars is apparent that the wheel motor, Tsinghua University, speed “switch to” pulse modulation “width” in the nineties is a relatively new technology, I was the inventor a patent application. After 97 years of technical maturity, the electric bike in the industrialization of production volumes. “Continental Dove,” Thousand Cranes “,” Red Flag “and other manufacturers are already in the database before, but they are in R & D stage. In 98 years of national standards (GB17761-1999) issued by the former, Japan November 2, 1995 — walk with the help of national standards, does not control the speed handle, and I, and Guangzhou Five Rams “factory,” Wei Roth, co- production pedal sensor detected successfully by Japanese standards, and be the first to enter Japan’s exports.

Second, “the technology of lithium batteries” to promote long way to go
Journalist: In your region next electric bike technology research, what is it? Comparison of current concerns of the industry in technology “lithium battery” how to think?
MA: Many electric bicycle components within each mutual interference between multiple paths and complex, if there are problems, could not immediately identify the location of the defect. Research should be the next alternative chip lead, the development of “wireless local communication.” For example, the console and the battery, the electrical contact not, but between different parts with each other using control technologies for wireless communication.

In addition, people are preoccupied with lithium in many technical indicators higher than traditional batteries, lead-acid battery technology lithium poses as a big step forward. But his management technology battery system is not perfect. In the long term, the recycling of lithium batteries is a problem to solve. Lead acid batteries do not belong to the “green” battery, but everything can be recycled. The lithium battery technology is not yet available can be recycled. The current treatment of waste lithium batteries are mainly used deep approach, this method of pollution at the same time, the accumulation of excess weight, to a certain depth and temperature of the environment that cause battery explosion. Consider this, I think the promotion of recycling of lithium batteries is not good in promoting attention when needed, or easily create new sources of pollution. asus A42-A3 battery asus A42-W3 battery
Third, consumers need to guard against deceptive slogan of the market
Reporter: Many manufacturers claim to be “self-production, as long as the foot can produce electricity, the technology is real?
Ma: In today’s market, many manufacturers of electric bicycles slogan unscientific, misleading consumers. Such as type self-production electric bike, the rider said the man to produce electricity, so there was absolutely no scientific basis. Only systems equipped with body retrieval energy, and only when braking to achieve “energy recovery”, so-called “not a foot, he electric” electric bicycles in both directions of the current up and down several times, is the damage to the battery. Consumers misled by this propaganda constant vigilance to avoid dupes. acer BTP-42C1 battery acer BTP-43D1 battery
Fourthly, the rapid development of electric bikes in China
Reporter: What are the factors that promote the rapid development of electric bikes in China?
Ma: In our country, promote the rapid development of electric bicycles from three factors.
Firstly, the traditional industries of China’s heritage. China has a bike base, the motorcycle, the traditional industries of modern society electric bike has a great influence.
Secondly, reform and openness, China’s rapid economic development, living standards of people raised, there are higher demands on the trip, a huge demand for the industry.
Thirdly, energy and the environment, many institutions, the Academy of Sciences, research in this area have increased. Tsinghua University plays a basic technique in this area of work for this study provides direction for development. acer BTP-44A3 battery acer BTP-52EW battery
The next development of electric vehicles today are faced with technology upgrades and advances, models of electric bicycles to go “light, small, energy-saving” direction, while the “engine” this paragraph, “a highlight of New York, more climbing ability of the slope, and much less important” direction.
Fifth, the technological level of China’s leading global electric bikes
Reporter: At present, the internal electric bike world what position?
Malaysia: Domestic electric bike in a leading position internationally. Marked by our technology are original, and better than other countries, and we can make the industrial production reliability. Europe, the United States and Japan and other countries rely mainly on imports from China. However, the quality of our product must be improved in many small workshops irregular reduce manufacturing costs through a variety of ways, engage in price competition, but it also diminishes the quality of production. If this problem can be solved, the more likely that China bicycles electric bike as a producer and exporter. acer BTP-58A1 battery acer BTP-59A1 battery
