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.

Cars are one of the most commonly used vehicles for commuting and since the origin of the automobiles, there have been various innovations in terms of types and kinds of cars. One of the earliest among these characteristic kinds was the electric cars or EV, also known as the battery electric vehicle or BEV which emerged in the 19 th century. Unlike the hybrid vehicles which perform with the aid of both internal combustion engines as well as electric motors, the electric cars make use of motor controllers and electric motors and function by means of the chemical energy stored in rechargeable battery packs. With the progress of time and advancement of technology, one of the adverse effects that hit human civilization was the ill-effects of pollution. Under such circumstances, it must be pointed out that battery electric vehicles more often make use of renewable sources of energy and therefore they do not emit exhaust fumes and minimize the risks of environmental pollution. These electric vehicles do not produce toxic smoke and are mostly soundless and are also capable of producing more acceleration compared to the conventional vehicles. The different variants of the battery electric vehicle include golf carts, electric scooters motorcycles, light trucks and because of their low dependence on the use of petroleum, it is possible to constrict the harmful effects of global warming as well. The most important constituent of the battery electric vehicles are their batteries and in mot circumstances, the prices of the batteries determine the expense to be incurred by the owner on the vehicle. However, they are still considered to be cheaper compared to the conventional vehicles and while the initial battery prices may seem high, the overall maintenance cost is not that expensive.
There are several reasons why the battery electric vehicles are more often a preferred option among enthusiasts. The fluctuation of rising fuel prices does not affect it and they are also successful in restraining vehicle energy costs by almost 90%. The source of electricity in ca battery electric vehicle may be obtained form hydro power, solar power, wind energy or nuclear power which ascertains the non-emission of carbon fumes which can cause harm to the environment. Batteries need to be recharged after stipulated priors of time and those costs are not so high and remain more or less constant compared to the inconsistency of fuel prices.
However, it is to be kept in mind that unless renewable sources of energy are used, electric vehicles cannot check carbon emissions and the batteries too require frequent replacements.

Electric Vehicle Batteries
Lithium Ion Batteries for Plug-in Hybrid and Battery Electric Vehicles: Market Analysis and Forecast
The automotive industry will launch dozens of new plug-in hybrid and battery electric vehicles as it begins the gradual process of moving away from petroleum based fuels and towards battery power. These vehicles will rely almost exclusively on lithium ion (Li-ion) batteries, while hybrid vehicles will slowly switch from nickel-metal hydride (NiMH) technology. However, Li-ion batteries today increase the cost of vehicles by 30 to 50 percent, which limits the attractiveness of the vehicles. ( www.bharatbook.com/detail.asp?id=127274&rt=Electric-Vehicle-Batteries.html )
The initial market for electric vehicles will be largely dependent on government subsidies and incentives; significant reductions in battery cost are seen as a requirement for the industry to grow to the nearly $8 billion market that forecasts by 2015. Japan, which has been a leader in batteries for hybrid vehicles, is likely to continue to play a leading role, while China, Korea and Japan are also likely to all be significant suppliers of electric vehicle batteries. There are currently more than a half dozen battery chemistries with unique properties for power, energy density and life cycle performance that are being commercialized.
