Market, called universal fast charging, voltage 4 ~ 6V, current 0 ~ 700mA. High voltage high load rapid change, of course, but too easily lead to the battery current to shorten battery life and high current will be a great heat, the temperature is too high causing the battery to explode easily is the security risk the most serious. 2 years ago have been several times since the summer high temperature, resulting in cell phone battery exploded and injured more people, we are interested can look to see, security is not really a joke. Finally, a conclusion: the charger is not charging faster, better.

Since the explosion of the battery temperature is too high after the news, many manufacturers have made a change in power, increasing the pressure limiting current limiting resistor, so that all under control voltage and current, and temperature is not high, dell, but the tension is too low and the battery can not be filled, one with an office half a day without electricity or high load capacity Battery is now a 1-2 full days as unhappy long after the battery capacity will decrease, affecting life. Recommend the use of major brands of chargers, such as land and sea connections, hair flying back and so on. Recently, the market has a new universal tax, Bo Tao Bo U.S. Department of the mark, listen to people say that if manufacturers in Shenzhen Bognes technology, plant Sakata. Bo Tao of three colored lights and chargers tested the charger I bought, very good electrical properties in the standard range, and fly back hair, and sea links and other major brands neck and neck . More cows enter, 1 5 m, all OK, a small shell rupture, 2 meters 5 times still no major problems. Still down from the fourth floor and the shell are rotten, the ground state is streaking, and here the power, measure, and gives no problems with the electrical properties, carefully reviewed the electronic components and joints welding, really solid materials. Dell Latitude E6400 battery, Dell Latitude E6500 battery, Ordinary universal charge and speak still down, and down just outside the solder joint on the whole machine does not work. My only regret, surprise, Bo Tao, or the appearance of color to the old egg-shaped, not beautiful, looking forward to the future, it will be even more beautiful. Price back hair, sea and land routes for cheaper, the cost is very high, recommend to try next.

Q: Regular replacement of the battery charger to recharge electric vehicles would not affect life expectancy?

Expert: each manufacturer’s chargers are generally individualized demand, not sure when the charger should not arbitrarily change. If the continued line of a longer mileage requirements, need to be equipped multiple chargers, you have to go to the corresponding brand of after-sales service department, so that the maintenance of professional instructors confirmed to be equipped with first wife charger on the battery life is good.
Q: The onboard charger and often will affect the vibration of life?

Expert: In order to reduce costs, the current charger basically did not do a high vibration-resistant design, so that chargers generally do not put electric cars, the trunk and the car basket. If you have to move cases, chargers, we should also packed with foam to prevent vibration. After a lot of vibration through the charger, its internal potentiometer will drift, making the whole parameter drift, resulting in state of charge does not affect the normal life of the charger will damage the battery formation.

Dell laptop Model Analysis

Among the many notebook brands, Dell (DELL) marketing strategy can be described as unique: a very long period of time, difficult for consumers to shop through the formal channels of an entity to buy Dell’s PC products, only through phone calls or visit the official website to order, and in a few days waiting for home delivery.

This is Dell’s direct sales strategy of pride, because of reduced profits of the middle of the channel to divide its product prices are generally lower than competitors, thus giving consumers more benefits.

But in the past two years, this sales model has revealed a growing number of issues, such as some people like to see for yourselves that will touch the books to buy, and some others do not have time to wait for several days (or even a week or two).

So now dell Inspiron 1150 battery has adjusted its marketing strategy, while maintaining the original based on the direct sales model, but also began to increase targeted physical channels, for example, and Wal-Mart, the National United States and other chain stores to cooperate as well as the incorporation of some of the gray channel and so on.

Dell’s product line planning

Dell’s notebooks are divided into two major consumer and commercial product lines, each of the following product lines subdivided into several series. Their difference is the appearance of a more personalized household notebook fashion, but also a variety of shell colors and patterns to choose from.

The appearance of commercial laptops are more mature and more stable, more suitable for access to conference rooms and other serious sites;, of course, some of the details of the high-end models dell Inspiron 1300 battery,dell Inspiron 1420 battery will also be more sophisticated workmanship.

Home Models

Household models have been the two main series Inspiron and XPS, which targeted at mainstream users Inspiron and XPS is targeted at gamers. But with the fast-growing consumer market, Dell’s consumer models will soon be subdivided into three series, an increase of one, called Studio, in high-end consumer brand.

At the same time, XPS of roles have also changed gradually from the fever-type into a high-end home game type, but will PC gaming market is entrusted to the newly added Alienware series (Note: Dell acquired Alienware in 2006 companies) .

Business Models

In the commercial field, Dell has had two series: Latitude and Precision, respectively, located in medium and large enterprises, as well as government, educational and medical institutions. But with the SME and SOHO owners of the blossom everywhere, Dell added an affordable low-end business models: Vostro series.

Of these three business series, we can be so understood:

Vostro stressed that cost-effective, the same limited budget was a lot of consumers favor the individual can therefore be seen as a range between commercial and household products.

Latitude is the most competitive in the mainstream business models, in durability, security,  Inspiron 1501 battery life, connectivity and remote management, etc., are fully taken into account the diverse needs of business people.

Precision is a mobile workstation, providing superior application performance and world-class scalability, mainly used in intensive graphic design, film and television special effects production and so require robust performance, areas of expertise.

Do you really use laptop batteries?

Laptop, are you using it? That you use the laptop batteries has mastered how much? Long-term use to connect the power of books-how to keep the battery good books do? Seem less important issue, in fact affecting the battery books life, want to use books longer so? then let us learn what battery to use bar!

1, the battery use of the program

Most notebooks have the automatic down-conversion function, so that the benefits of the books is to maximize battery charger battery life. Many people who use the Celeron may have questions about books, our books do not have this feature, is not naturally less power out? CPU is only one part of the cost of electricity, in fact, the order should be like electricity: LCD> CPU (speed) “graphics” Wireless LAN> CPU fan. In other words, in addition to CPU, we can also start from other areas, the maximum reduction in power consumption.

In the Windows XP Control Panel, there is a power management option, the “power scheme”, the set up LCD screen is idle about 10 minutes off the most reasonable, while the hard disk will have to set more than 15 minutes more appropriate. The hard disk to start the moment requires a certain power did not say, frequent start and stop the damage to the hard drive is quite big. Of course, you can also manually turn off the screen, most of the books through fn function key + F3 to achieve.

Set LCD, hard drive shut down time, if you want to further conserve Dell Inspiron 1501  battery power, but also need to adjust the operation of the system state, it is not a Windows XP can do. With Thinkpad, for example, most of the books have a built-in battery management software, general books will provide eight screen brightness adjustment, although the brightest state of access to the best visual effects, but it is very, very power-hungry, so , edit a document or some other general applications to adjust the screen brightness to a lower 6 or 7 the most appropriate. At the same time, CPU can also set the best Dell Inspiron 1520  battery performance, CPU fan running status set to “balanced” more reasonable.

Some low-priced books there is no battery management software (because there is no built-in power management chip), but you can use a common battery monitoring software to manage the battery.

Sample used in the T43, is running at full speed when playing DVD discs, the battery usage time is only 2 hours 37 minutes, while the optimized program can be achieved when using a long 3 hours 17 minutes or so, raise obvious. Set the screen brightness, CPU speed, fan speed.
 
2, the correct charging method

Many people use books the hp pavilion battery , I saw that the power began to charge less than 100%, but this would accelerate the reduction of the total capacity of lithium battery power for a long time go, battery life much shorter time, but also greatly shortened life expectancy . It is therefore recommended to limit the charge less than 10% re-charge, and be mindful not to set too low, such as the use to only about 3% charge left, which is not enough science. Power shortages must be set up when the alarm is generally less than 10% of the police as well, less than 3% of the serious alarm means that the battery has been insufficient to support the boot into the system the next time. A lot of battery management software is less than 96% of the default start charging, so charge will damage the battery, so be sure to change this setting. In addition, it is best off charge, so you can play a role in conservation of the battery.

3, discharge necessary?

If the books for a very long battery power considerably reduced, the depth of discharge can try to “save” it. This is a “dead horse like a living horse medicine” approach, less than a last resort, better not to do so. Discharge The easiest way is to constantly run the program, less than 3% in electricity to restart the books into the BIOS to run the vacancy until the automatic power-off date. Then the depth of charge, charging time to reach eight hours, but not more than 12 hours, which would allow Li-ion battery to restore some power.

Winter use of laptop should pay attention to protecting the screen and battery

In the winter, when the use of laptop should pay attention to two questions to the winter, especially in the north of the friends, the temperature will be lower relatively speaking a lot of the South! Are negative degrees. With such a low temperature on the notebook’s two places the greatest impact! One is the notebook’s display, which is now said TFT screen, another one is the sony VGP-BPS2 battery.

1. For the impact of TFT screen
Winter outdoors using a laptop the first one disadvantage is that will hurt notebook TFT screens, TFT screen, the best use of the general temperature of 40 degrees to 10 degrees, more than this temperature range, color TFT screen becomes abnormal, and the aging accelerated, if the In the low temperatures range from the use of TFT screen may appear dead pixels, re-TFT screen is causing permanent damage. Northeast friends may have had experience, cell phone screen, in the cold outdoors can become very bright color of pale, in fact, this is the screen inside the TFT liquid crystal material has begun to degeneration, and when the liquid into a crystal inside the screen, your LCD screen on the permanently damaged.
    
2. For the impact of sony VGP-BPS2A battery,sony VGP-BPS2B battery
The second disadvantage is that low temperatures will hurt laptop batteries. Most notebook computers now use lithium-ion battery, this battery has the advantage of weight, large capacity, but also brought a very chilly this shortcoming. An ordinary civil zero when the lithium battery capacity would be reduced 20 percent, while the capacity to reach minus 10 degrees may be only about half that. The North’s friends all know that winter is dead on the phone if the arms of a warm heating can be used for a period of time, this is because the battery is too low because of the temperature caused by an electric discharge with no success. This use of one or two may not have much impact on battery life, but if you use a long time that the sony VGP-BPS2C battery  may cause permanent damage.

Therefore, maintenance of the North’s friends need to pay attention to your laptop, and the temperature is too low, can be harmful to the notebook screen and battery.

Portable terminal with the prospect of practical application of fuel cells

Posted by admin on December 14, 2009

Portable terminals for small fuel cell has entered the practical stage. Toshiba in March 2009 at its manufacturing prior to the first portable terminal with a small fuel cells. U.S. MTI MicroFuel Cells will be 2009 years, STMicroelectronics (STMicroelectronics) in 2010 in a small fuel cells. In addition, Sony, Sharp and Panasonic and other major Japanese electronics  makers are all in 2012 after the adoption of the Second Corps of small fuel cells.

During the interview, I encountered the most questions is, “Toshiba in March 2009 before the adoption of the (small fuel cells) is used in what products it?.” This is because the previously announced the adoption of portable terminal fuel cell enterprises, mostly postponed the adoption date, in fact this means that small fuel cells practical plans thwarted. Moreover, the current from the end of March 2009, less than 2 months time. Although time is running out, Toshiba has not released any news. Prior to the deadline I had on this issue tirelessly repeatedly asked the Toshiba.

Another point I care about is that this fuel cell is limited to the Toshiba can make their own decisions whether or not the portable terminal to use it? In particular, when the phone is to use a small fuel cell? If this goal is achieved, then the Toshiba will be able to not only increase production, but also to attract many outside Toshiba’s fuel cell companies involved in the field.

January 29, Toshiba released the information on this question. Nishida president at a press conference by the “business structural reform” in his speech announcing the end of the portable fuel cells practical program schedules. That would be March 2009 before the start of an external portable terminal sales of fuel-cell dell Inspiron E1505 battery charger. Strive to March 2010 before the realization of “mobile phones” and “notebook computer” two kinds of small fuel cells practical (Chart).

Toshiba announced that it will be achieved by 2010, mobile phones with small fuel cells for practical use, this meaningful. This is because, if the realization of a mobile phone with small fuel cells for practical use, then the mobile phone market is huge, and therefore easier to have a relevant technology to other vendors involved in this field, it was easier as universal access to small fuel cells allies. Regardless of the company’s fuel cell technology, how well these techniques alone may not allow portable terminals to popularize the use of fuel cells. The more relevant enterprises to participate in infrastructure construction and technical innovation will be able to advance more quickly. The dominant cell phone carrier, this trend is accelerating, fuel cell as a cell of choice for best-selling days in the city may soon come.
