Concerned about the new technology of pure electric vehicles: external plug-in hybrid electric vehicles
People’s Liberation Army unit with the Shanghai Jiao Tong University, developed outside the plug-in hybrid electric Digital Camera Battery vehicles, by experts known as the “electric – oil hybrid electric vehicles.” It is in the fifty or sixty kilometers driving battery-powered, as a pure electric vehicle use, longer travel distances to use the fuel the engine side. The car use of lithium manganese oxide cathode materials for lithium-ion battery (216V), also in parallel the voltage 280V of the stacked-type super capacitor (2.5F) to upgrade the power and energy recovery.
The United States, Canada, in 2005 started to part of the “oil – electric hybrid electric vehicle” to “electric – oil hybrid electric vehicle” test, specifically, is mainly sold to Japan’s Toyota Prius cars in the Ni-MH battery (6.5 Ah) replaced by bigger, higher-capacity lithium-ion batteries, each conversion costs around 12,000 U.S. dollars. In China, the improvement is to a Beijing Jeep has successfully converted into two kinds of power can be used alone, any switch plug-in hybrid electric vehicles outside, power structures and control systems transformation difficulty and workload was relatively large, innovative The significance for the future of R & D, production and “electronic – petrol hybrid electric vehicle” provides a very DSLR Battery Grip valuable experience.
Development of electric cars need to be understanding to solve several problems
Electric vehicle batteries should be based on safety first. Batteries used in electric vehicles must be placed on various indicators of safety first, followed by the specific energy, life, price and other factors to form the comprehensive performance. Zinc – air batteries and lithium iron phosphate as cathode of lithium-ion battery, no doubt in the existing types, all kinds of power cells in a dominant position. Should seize the opportunity to make full use of my two batteries a good basis for the current and momentum, to give timely support and policy incentives to make it accelerate development.
Re-understand the scope of application of pure electric vehicles and power reserves. At this stage can be so conceived: China’s urban electric transport vehicle power can be zinc – air battery-based, point-to replace Canon EOS 30D Battery Grip or electrode material, in every city to form one or a few batteries or the regeneration electrode materials factories and a number of bus lines support services; city cars can be used in the main use of lithium iron phosphate as cathode of lithium-ion power battery, if the battery weighs about 150 kilograms, electrical storage 15kWh, renewal of driving 150 km, is sufficient for most users, while the Vehicle weight is not necessarily the number of vehicle weight than fuel oil. Only the initial purchase price may be expensive, but with the battery falling prices and vehicle production increased, prices will continue to decrease. I think that the fuel trucks in accordance with existing indicators (continued driving mileage, speed up to 100 km / h time, the maximum speed, etc.), the overall requirements of the city the use of pure electric vehicles is unreasonable, especially in the pure electric promote the use of the early stages of vehicle, but such a requirement is unnecessary.
Obvious advantage of pure electric vehicles
China has always attached great importance to clean and efficient vehicle technologies. Electric cars have been included in the national 863 major projects, the development mainly in the vehicle fuel cell vehicles, hybrid vehicles and pure electric vehicles, three kinds of technology.
As opposed to hybrid vehicles and fuel cell vehicles Canon EOS 40D Battery Grip and pure electric vehicles have their own advantages. Pure electric vehicles with electric motors instead of fuel machine, low noise, no pollution, motor, oil and transmission accounted for less space and weight can be used to compensate for the battery needs; and the use of a single electric energy, electric control system for hybrid electric vehicles compared to greatly simplified, reducing costs, but also compensate for the battery part of the price. Moreover, the pure electric vehicle battery power at night to use the cheap, “Valley Electric” to recharge, you can stabilize the grid’s peak – valley difference. Right owners, the use of time-denominated cheap “Valley electricity”, and perhaps to spend 2-3 million electricity will be able to save oil costs 50 yuan. In short, the state and the power grid, on the environment, users are lot of benefits. Should therefore be to develop electric cars, and in pure electric as the main operating mode of the “electric – oil hybrid electric vehicles.”
At present, some companies have started trying, such as: Xianyang g Energy Co., Ltd. with the power of lithium iron phosphate lithium-ion battery at the Beijing University of Technology in collaboration downloading has become a pure electric cars; Powerzinc Battery (Shanghai) Co., Ltd. with the production of zinc – air batteries for the development of pure electric passenger car to the other companies in groups to provide a wide range of pure electric vehicles power. In addition, PLA troops and Shanghai Jiao Tong University, studied electricity – oil hybrid technology, and applied to electric vehicles.
The industry is now widely estimated that fuel cell vehicles can pose Canon EOS 300D Battery Grip a real problem, at least 10 years -15 years. In the pure electric vehicles, due to progress in the second continuous power battery and pure electric vehicles, although not a significant scientific and technological special funding, but it is “getting results Yum” trend. Should now be addressed to those who will soon shade the “Willow” poured some “water.”
China and South Korea Li-ion battery business in Shenzhen “handshake”
Chemical and physical power by the Chinese industry associations and the next generation of rechargeable battery R & D group of South Korea co-hosted the “2007 China and South Korea Li-ion battery technology exchanges” on January 17, 2007 held in Shenzhen from China and South Korea on behalf of 165 attended the meeting. Major domestic manufacturers of lithium batteries, BYD, force God, BAK, B & K, Hua Yue Bao Guangyu TCL, ATL Deng Jun send technical director to the meeting.
China and South Korea is the world’s leading producer of lithium-ion battery countries, China is the world’s second largest producer of lithium-ion batteries in 2006, the output of more than 900 million, accounting for 35% of the world market. With the portability of electronic products, miniaturization, for lithium-ion battery technology and newer requirements are increasingly high. Since last year, due to the rapid rising nickel prices, resulting in nickel-cadmium, nickel metal hydride batteries rapid increase in costs Canon EOS 350D Battery Grip, the market is gradually shrinking, cell phones, digital cameras, Bluetooth headsets, game consoles, power tools, electric bicycles and other products on the continuous demand for lithium-ion battery increase, China’s Ministry of Information Industry of the overall issue 3G licenses, will provide lithium-ion battery to provide a more broad market.
The next few years, China and South Korea Li-ion battery industry in the global market in order to occupy a larger market share, we must invest more in technological innovation and financial and human resources. To this end, all enterprises need not only an independent technology development, but also through inter-firm or industry associations co-operation through international exchanges to promote technological innovation to carry out.
The meeting, the two companies agreed to continue efforts to South Korea Li-ion battery technology exchange Bancheng exchanges between enterprises of both countries and industries and information technology event, held annually in China or South Korea once, for two inter-enterprise bridge the technological exchanges and cooperation, promote bilateral scientific and technological achievements between the lithium battery industry, the introduction and output, and improve enterprise’s technological innovation capability.
Friendly and agreed to by both parties, “2008 China and South Korea Li-ion Canon EOS 400D Battery Grip technology exchange” will be held in Busan in South Korea.
Battery has reached its environmental requirements are no longer advocated centralized recycling of used batteries
Speaking of a waste batteries, people will think of environmental pollution, many environmentalists and member of the public specifically to collect used batteries in order to reduce environmental pollution, but yesterday’s learned from the environmental protection department to collect used batteries but may cause pollution.
4 years collecting batteries almost 8 pounds
Wenchang Road Primary School is a drizzle of sixth-grade students, is also a holiday Eagles squad of players, from second-grade, light rain on and the team of a dozen players with the use of winter and summer vacations in the living quarters where the collection of used batteries, it has been adhered to four years.
In order to as much as possible to collect used batteries, light rain they collected from the initial visits discuss ways to become proactive, one to leave, light rain will be holding a small shovel in the district’s green belt around in search, while it is time-consuming and hard work, but the laptop battery rain this way, each vacation ended, players will put the collected used batteries stored in a light rain at home. “Picked up, and do not know where to go to be handed, so I used the bag installed on my kitchen at home.”
Four years later, and used batteries have piled up, take a scale, said a full 7.6 pounds weight, will allow light rain headache, she still did not know how to deal with these hard-collected “is thrown away.” Light rain finally put the old battery pack up thrown into the district health room, “you can easily throw really do? Then we do these four years, not to no meaningful?”
Do not encourage recycling of used batteries
As environmental advocates, living in the prosperous garden TUNG have the same questions. Mr Tung said that households living in the district where a lot of household residents need to use the battery at home electronic products Tingduo may be that we have a question: how to use the remaining cells do? “Some residents are a direct throw away the battery, and some close up and sold to income cardboard, and 5 cents a pound, but two ways I do not think properly, if the district where the laptop batteries establishment of specialized waste battery recycling point enough. ”
Members of the public in an interview, almost one hundred percent of the people considered hazardous waste batteries, more citizens have said that should be sold next to the battery shop or counter set up collection points for used batteries, or simply be recovered by the battery factory again.
Jiaxing Municipal Environmental Protection Bureau, Mr. Xu and regulations Xuanjiao Chu told reporters inside the battery containing mercury, nickel and other heavy metals, these heavy metals if the infiltration of the surrounding land and water, pollute the environment. But there are more members of the public access to the batteries, according to national product quality requirements, the current dry factory must meet the “low mercury” or “mercury-free” environmental quality requirements, environmental pollution is negligible, so can these waste battery, together with ordinary garbage handling, no special separation and recovery, “not to promote a great deal of recycling of waste batteries together because, after the total content of heavy metals bound to increase, this may instead be caused by concentration of pollution, such as rain, as the students , it should be dispersed throw used batteries should not be thrown into a trash can where to focus. ”
Mr. Xu also said that some small shops selling batteries are fake and shoddy products Dell Battery, these batteries will cause pollution of the environment, so the public can call the love of environmental protection to report 12369.
