Magui Long: “Lithium batteries” electric vehicles to promote long way to go
Tsinghua University Magui Long, 20 electric bicycles for many years been committed to technology, to be the industry referred to as “the first person of Chinese electric car.” Professor Ma Guilong early inventions technology laid the foundation for industrial development and direction, and free to contribute their own patents, and use their research results to guide the industry in technology HP PAVILION DV4000 Battery.
Interview Record:
, Technical Research Course
Reporter: Are you in the electric bike industry is a technology veteran, can not be introduced to the history of your technology?
Malaysia: Domestic electric cars first appeared that the wheel motor, Tsinghua University, the “speed switch to”, “pulse width modulation” in the nineties is a new technology, I was the inventor applied for a patent. After 97 years of technical maturity, the electric bicycle into the industrialization, production volumes. “Continental Dove”, “thousand cranes”, “Red Flag” and other manufacturers already have some in the base before, but are in R & D stage. In the 98 years of national standards (GB17761-1999) before the promulgation of Japan November 2, 1995 — foot through the assistance of national standards, does not allow speed control handle, 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, “lithium battery technology” to promote long way to go
Reporter: In your next electric bike technology research area is what? Comparison of the current industry concern in the “lithium battery technology” how to think?
MA: Many electric bicycle components within each mutual interference between the many complex routes, if there are problems, could not immediately identify the fault location. Research should be the next alternative chip lead, the development of “wireless local area communication technology.” For example, the console and the battery, the electrical part of the no contact, but between the several parts with each other through wireless communication technology control.
In addition, people are concerned about lithium than in many technical indicators superior to the traditional lead-acid batteries, lithium battery technology is the emergence of a major step forward. But its battery management system technology is not perfect. In the long run, lithium battery recycling is a problem to be solved. Lead-acid batteries do not belong to the “green” battery, but can all be recycled. The lithium battery technology is not yet available can be recycled. The current treatment of waste lithium batteries are mostly based on deep approach, this method of pollution at the same time, accumulation of excess weight, up to a certain depth and temperature of the environment likely cause battery explosion. Consider this aspect, I think that the promotion of lithium battery recycling is not sound in case of need careful promotion, or easy to generate new sources of pollution.
Third, consumers need to guard against misleading slogan of the ACER TRAVELMATE 6000 Battery
Reporter: Many manufacturers claim to be “self-generating”, as long as the foot can generate electricity, the technology is real?
Ma: In the current market, many electric bike manufacturers slogan unscientific, misleading consumers. Such as “self-generating type” electric bike, said the human cycling to generate electricity, so that there was absolutely no scientific basis. Only body equipped with energy recovery system, and only under braking to “energy recovery”, the so-called “step foot there a power” of the electric bicycle back and forth the current up and down repeatedly, is the damage to the battery. Consumers misled by such propaganda to be constant vigilance to avoid fooled.
Fourth, the rapid development of China’s electric bike
Reporter: What are the factors that promote the rapid development of China’s electric bike?
Malaysia: In our country, to promote the rapid development of electric bicycles from three factors.
First, China’s traditional industries of inheritance. China has a basic bicycle, motorcycle basis, such traditional industries to modern electric bicycle company has great influence.
Second, from the reform and opening up, China’s rapid economic development, people’s living standards raised, there are higher demands on the trip, a huge demand for the industry.
Third, energy and environment issues, a large number of institutions, the Academy of Sciences, the research into this area increased. Tsinghua University, plays a technical base in this area of work, for this study provides direction for development.
The next, the development of electric vehicles are now faced with technology updates and breakthroughs, electric bike models to go “light, small, energy-saving” direction, while the “motor” of that paragraph to “a greater moment of New York, more climbing slope capability, and much less material “direction.
Fifth, China’s technological level of the world’s leading electric bike
Reporter: At present, electric bicycle inner world in what position?
Malaysia: Domestic electric bike in a leading position in the international arena. Marked by our technology are original, and better than other countries, and we can do in industrial production, product reliability. Europe, the United States and Japan and other countries mainly rely on imports from China. However, the quality of our product needs to be improved in many small factories irregular down manufacturing costs through a variety of ways, engage in price TOSHIBA PA3383U-1BRS Battery, but also reduces the production quality. If this problem can be resolved, most likely as China’s electric bike bicycle as a producing and exporting power.
