A few days ago at the end of the 79th Geneva Motor Show, electric vehicle, as the representative of new energy vehicles by all sides. “The Sound” behind the electric vehicle manufacturers face the challenge can not be avoided, how to increase mileage of electric cars is still an urgent need to solve business problems.
The next few years, the upcoming electric vehicle continued driving for many miles shorter “city car”, these new energy sources, how to expand the automotive market capacity are uncertain.
Car manufacturers eager to zero-emission electric vehicles can play the important task of expanding product lines. Not long ago, the Ford Motor Company CEO Alan Mulally said the company will focus on the development of electric vehicles. He said: “the next 10 years, consumers will gradually found that electric cars become the Ford family of products an important part.”
In order to popularize electric vehicles, car manufacturers are planning to take two approaches: the establishment of fast charging stations or laptop batteries  replacement stations. Nissan Motor Co. Senior Vice President Andi.Paerma said: “because of poor infrastructure, large-scale electric vehicle to market the first period, the main scope of activity confined to the city.” He pointed out that once the battery fast charging stations and the replacement of stations can be universal, electric vehicles will be with the traditional car, unimpeded.
Mercedes - Benz, vice president of R & D and engineering hebe.Te.Kele think, fast charge will allow the company to reduce vehicle battery life. “Do not trust only a few minutes, the Dell laptop battery charging can be done lying.” He said: “Charging a two hour or half an hour battery life can be guaranteed. Otherwise, detrimental to the battery ‘health’, consumers buy the batteries can not meet the manufacturer’s use of trademarks Note. “Parma’s opinion with this tit-for-tat, he said, as long as the control properly, fast charge will have a negative impact on the battery. Express battery charging theory supporters think that once reached a certain number of commercial battery charging station will be the elimination of consumer concerns about Dell Latitude D620 battery  power.
Battery replacement stations set up ideas have not been fully recognized. European Product Manager, Mitsubishi Corporation Bote.Slopu suggested that the current vehicle battery models, a variety of styles, which have caused trouble for the replacement. He said: “battery replacement stations for various electric vehicles ready batteries Dell Inspiron 600m battery , Dell Inspiron 700m battery , Dell Inspiron 8600 battery , Dell Latitude D420 battery , this idea is unlikely to achieve. Battery replacement for various models of station it is very difficult and style put the battery fully ready.”
“Building a better space,” co-founder Shai Agassi set up the first car battery replacement stations, the idea of him are users of electric vehicles entering the car battery replacement stations, will run out of battery power to replace the electric Dell Latitude D520 battery is full, then continue to the road vehicles traveling. At present, the “build a better space,” the company is working with Renault - Nissan cooperation, argues the idea of Shai Agassi.
In June this year, Mitsubishi will launch electric vehicles in Japan iMiEV. Hislop said the company’s positioning put electric vehicle commuter car in the city. He said: “electric cars are not suitable for all environments.” According to Mercedes - Mercedes-Benz R & D management committee members introduce Thomas Weber, the company 70s of the last century have experimented with electric vehicles to replace the Dell Latitude D600 battery  in order to increase the practice of mileage for the development of a new generation of electric vehicles, the company does not intend to set up a way station battery replacement vehicles achieve universal.

Conversion efficiency of 8.5 ~ 9%, better than the market average volume production scheduled for the second quarter of the Listing
By Yinghui Technology (3523) to invest in eight of the thin-film solar battery  factory electric sun, a few days ago the first successful test output High efficiency double-layer amorphous silicon / microcrystalline silicon (a-Si/μc-Si) thin film solar cells, is scheduled to mass production shipments in the second quarter this year, Sony battery capacity planning 15MW, the conversion efficiency of up to 8.5 ~ 9%, better than the market average conversion efficiency of only 6 ~ 7% of the single-layer amorphous silicon (a-Si) solar cells.
The company said that the technical team combined with years of experience in vacuum coating and optoelectronic semiconductor technology team members, using turnkey technology and related vacuum equipment, the only access for the European Institute for Technology Transfer in Germany Solar power production of double-decker solar cell turnkey solution.
At present, the eight-yang to double high efficiency battery as the main sales products VGP BPS8 , VGP BPS9 , VGP BPS9/B , the market elasticity of demand-based production of single-layer amorphous silicon (a-Si) solar cell or multi-layer amorphous silicon / microcrystalline silicon (a-Si/μc- Si) solar cells, and production line machine with the existing plant has production capacity scalability, future expansion of equipment at low cost.
The company pointed out that the first line in assessing when a large area at the time CIGS production technology have reservations about, and therefore double (Tandem Silicon) thin film solar power industry as a cut of the first phase of products BPS9A/B , BPL9 , BPS10  , CIGS technology for the future widening of eight-yang primary assessment of production technology, with production units in the Sony laptop Battery current R & D collaboration.
In addition, through mass production agencies design and yield optimization, the city’s eight production lines with plating equipment Products Triple Junction (> 11%) of capacity, R & D programs also strive to do three-tier control coating of the raw materials cost , the current parent company toshiba battery , Yinghui Technology has been the introduction of Roll-to-Roll equipment, the next in a vacuum process laptop battery and optoelectronic semiconductor expertise, combined with Yinghui of equipment and technology will be available Express cut curly thin-film solar power product development.

Today, the electric bicycle has been an increasing number of people selected as the means of transport, however, disappointing quality batteries  C1295 , D5318 , 6Y270 , 1691P to become the pain of people’s minds: Why is commitment to the cycling business mileage does not always run?
A new battery is not effective
Members of the public in July last year she had got a buy electric bicycle, when the sales staff promised electricity at an adequate case can be closed for more than 50 kilometers. And she had got from the Wanda Plaza, near the home to JIANGBEI work units, about 20 kilometers a day.
In January this year, as usual she had got to ride electric bikes go home after work, intend to go near the vegetable market to buy vegetables, the suddenly discovered the electric laptop battery . She has been wondering: Why can clearly committed to running 50 kilometers, this road has no more than twenty kilometers of electricity? After negotiations with the merchants, the other side She promised to give a new replacement battery, but just replace the battery mileage traveling 20 kilometers only.
Quality has become the focus of the battery complaint
In fact, quality supervision 12,365 hotline received a total of 129 last year on the electric bicycle quality consultative and complaints, of which most of the actual mileage on the battery.
“It’s like propaganda merchants, like car fuel consumption, are at a very satisfactory state of the data, but in reality with the electric bicycle configuration, consumer habits, there is both good and bad road riding relations, in fact it is very difficult to achieve. “saint leopard Ningbo Battery Co., Ltd. sales department responsible for supporting IP-hi to remind people that” some non-brand electric bicycle enterprises, often through false standard ThinkPad T40 battery capacity, jerry-built, refurbished or counterfeit batteries and other brand-name acts to reduce costs. ”
Then, put a new battery why they fail to reach the ideal traveling effect?
It is understood that the business will usually promise: from the date of purchase within 6 months occurred in the quality of the replacement of new battery problem, 6 months to a year on the maintenance of the replacement battery, continuous use to happen after one year shall not be responsible for business questions. However, in practice, some businesses even in the specified period of time give the consumer the replacement of the ThinkPad T43 battery  has little new, are generally oriented to the renovation. According to the current market price, a group of new 36-volt batteries selling to 440 yuan, 48-V will be 540 yuan or so, businesses can save a lot of cost.
With a new battery has about
Trade and Industry complaints hotline 12315 and the quality supervision department warned consumers to re-assemble the battery at a time when attention should be paid to view the complete Product signs, including the manufacturer name, product model or specifications, the date of manufacture, etc.; Show outside the markers is consistent, it is best not to buy No rated battery label. In particular have to pay attention to  Inspiron 9200 battery  pile head there is no welding marks, if there is welding marks, the battery is likely to be refurbished. If the battery shell has up to see “W” or “preserve” the words have to pay attention, so that the  Inspiron 600m battery manufacturers is likely to be recovered off the battery repair.
