Tech heavyweights hope to speed the development of alternative power sources for mobile PCs

An industry standards group that includes chip makers Intel and STMicroelectronics has published a document detailing the requirements a fuel cell technology would need to power a mobile PC, the group says in a statement.

The new guidelines from the Mobile PC Extended Battery Life Working Group should help speed the development of longer lasting fuel-cell power sources for notebooks and other mobile computers, a development viewed as important for the growing popularity of Wi-Fi and other wireless Internet technologies.

The development of wireless power supplies has lagged mobile Internet efforts. Batteries still last only a few hours in notebook computers before needing a recharge, but the group says fuel cell systems could last for days.

The guidelines will help developers of fuel cells for mobile devices, such as Millennium Cell and Tekion Solutions, by outlining key technical requirements for fuel cells to work well inside a mobile PC.

The technology is available today to put a fuel-cell system inside a notebook PC, but it wouldn't be able to supply enough power for the average user, says Andy Keates, power sources enabling manager at Intel and a member of the group.

"You could build a 10-watt to 12-watt [fuel-cell] power supply now, which is fine for a PC not doing very much, like using Word," he says. But turn on the DVD player, which requires 20 watts of power, and you run into trouble.

Coming Soon?
Next year, the first external fuel-cell power sources will likely be available, Keates says, and will likely find use among people working in remote areas without reliable power, like field researchers or the military.

The main trouble with fuel-cell systems is they're too big to be put inside notebook PCs--that's why it's easier to build an external fuel cell power supply, Keates says. A fuel-cell system requires more space than a battery because it includes the fuel cell itself, as well as supporting systems similar to a car engine, like a fuel pump, cooling system, and starter battery.

Batteries require few supporting systems.

Another engineering hurdle is that fuel cells operate differently than batteries, the group says. Fuel cells provide a steady supply of power, whereas power demand in notebook computers is very uneven, driven by bursts of power demand as different parts of the notebook, like the DVD drive or hard drive, are tapped for use, the group says. The stored charge of a battery matches this kind of uneven power demand, but fuel cells need careful management.

The group takes no position on which power supply technology might win the battle for notebook supremacy, says Keates.

"The industry has a lot of opinions about which one is going to be the winner. The fuel-cell companies are very confident, but the lithium-ion battery makers point out their 15 years of service and constant improvement. It's an open race," says Keates.

The fuel-cell guidelines cover size and power issues as well as electrical, mechanical, control, thermal, environmental and regulatory aspects of fuel cell designs for mobile PCs, including those made for use inside a device, and external fuel cells.

The Extended Battery Life Working Group was formed in 2002 as a collaborative effort to lower barriers for new power technologies aimed at mobile PCs. It includes PC-related companies such as Microsoft, Dell, and laptop contract manufacturer Quanta Computer, as well as battery and fuel cell developers. It took the group six months to develop the fuel-cell specifications, Keates says.

How to identify genuine and fake mobile phone batteries

At present, the cell phone of the brand has many good and the bad. However, there are a lot of the market is flooded with fake batteries so that consumers can buy batteries when difficile truth, not to gain the upper hand. In addition, some illegal phone dealers, the sale of real cell phone equipped with mobile phone batteries, in order to reap illegal profits. Short battery life is not only false but also because of damage to voltage instability in the highly mobile phone. Consumers should be in the following areas to identify the authenticity of cell phone batteries. Dell 1691P battery

First, the length of standby time
Battery standby time is a measure of the length of the pros and cons of an important indicator of Dell 3149C battery. Battery standby time is the length of the battery constitutes a single battery charge of the balance of the decision. Really battery standby time and a detailed description of the logo should be basically the same. The false identification only half the time. The number of poor-quality batteries are used in the secondary Dell Y9943 battery for core kernel, together with the new packaging by the assembly. If the seller does not guarantee standby time in line with the prospectus, you will not be able to buy the batteries. Some sellers in all sincerity and seriousness, in fact, he did not know the actual battery capacity, more than just oral. This Dell 6Y270 battery is generally poor quality of cell manufacturing. If the purchase of stand-by found a short time, the request should be returned immediately.

Second, the battery capacity
Cell phone batteries for the general capacity of 1000 mA / hour or two 1000mah. Some did not leave the battery capacity of the logo, the logo has also illegible. Can also get the battery cell phone repair shop to measure current, so as to the authenticity debate. Now we are using lithium batteries, lithium batteries and is similar to sections 5 and 7, the size of the batteries together, with switchgear and protection of the circuit. Therefore, it has a certain weight. If you buy a lithium battery light on the core battery capacity, the batteries may be a problem. General 900mah lithium battery core weight 35g, if a piece of the Dell 75UYF battery cell batteries and other equipment and lack of casing the weight of 35g, this battery that may be false.

Third, security
Cell phone Dell U4873 battery are flammable and explosive materials, if not an internal battery protection circuit, easily deformed, leakage, or even an explosion. However, many low-quality batteries at low prices to attract consumers to remove the piece of circuit board protection, in order to earn greater profits. This market has a lot of unsafe batteries, it is difficult to identify from the appearance. The best time to buy a regular mall to buy Telecom.

At present, the market’s three main mobile phone batteries: Lithium-ion batteries, nickel-metal hydride batteries and nickel batteries. As a result of the largest-capacity lithium-ion batteries, long standby time, light and mobile phone battery is the main species. So, above all lithium-based Dell TC023 battery

standard cell phone battery performance

Cell phones should be in line with the standards which
A standard cell phone battery performance should be as follows:

Appearance: cell surface texture color clear, uniform, clean, no scratches and damage; Dell Inspiron 500m battery labels should be printed on the battery type, the type, rated capacity of the standard voltage, the signs are negative, the manufacturing plant, 000. On the phone when they want to handle non-blocking smooth, elastic appropriate, and with good hands, a reliable locking; metal piece no scratches and black hair is green.

Battery Performance: standby time, talk time is actually a relative concept, test the Dell Inspiron 510m battery capacity of the consumer is a comprehensive, that is, standby, talk time at the same time. Simply put, the battery’s rated capacity should not be less than the standard size of 95% of the full power to place 28 days, the minimum capacity of not less than 60% of rated capacity, battery life of less than 400 times.

Safety: cell phone Dell Inspiron 600m battery over-current protection should be internal, external, and so lead to short-circuit current is too large, automatically cut off the loop, so as not to burn or damage to the cell phone; lithium-ion batteries have been sufficient to protect the other line, when the use of non-standard electrical appliances , To pay too much electric current when the power supply will automatically cut off, do not charge into the lead in normal cells, can automatically back to the turn-on status.

Termination of the charging control functions: mobile phone Dell Inspiron 6000 battery should be an internal temperature sensor, battery charger to charge for the provision of temperature signals the end of the charging control.

Production technology and raw materials: the production of cell phone technology is not complicated, but why cell phone market, the passing rate so low? Here there are two main reasons: First, manufacturers in pursuit of illegal profits and reduce costs, lower prices in order to scramble the market, used improper means to use defective materials or even scrap the assembly cell phone Dell Inspiron 630m battery; and the other is in the process of cell production of a number of key Factors have not been strictly controlled and to use components caused by incorrect parameter, so consumers should be chosen carefully to identify their true strengths and weaknesses
