Notebook battery fully charge and discharge error

Notebook battery fully charge and discharge error

Notebook computer equipped with the original battery, after a period of time after use, there will inevitably be the case of standby time. Some users said: “depth with repeated charge-discharge method, be able to resume the performance of the battery, thereby extending the battery life.

To a correct understanding of this issue, start a notebook about the type of laptop battery used. As we all know, in 1995, before the production of notebook computers are basically used to power nickel-cadmium batteries. In the use of such batteries, if not the correct way of charging and discharging, the battery will have a “memory effect”, thereby reducing the battery’s actual capacity, the elimination of this “memory effect” is the best way to repeatedly charge and discharge depth manner. With the emergence of nickel-hydrogen batteries, battery capacity has improved significantly, but the “memory effect” did not completely eliminate the shortcomings.

In recent years, lithium-ion batteries in notebook computers has been rapidly increasing, largely as a result of lithium-ion batteries have been the elimination of the “memory effect” problem, it is used repeatedly to restore the depth of Dell inspiron 1545 battery charge-discharge performance of the method is not applied. But why lithium-ion battery capacity or the will to reduce the problem? Have a fundamental reason for this situation is used in notebook computers and the original lithium-ion battery in the built-in battery management systems.

Battery Management: At present, in notebook computers, almost all adopted the “battery management” and “charge-discharge control” of two chip-level management systems. The “battery management chip” placed in the notebook computer itself, the chip registers in the memory of the computer used in the capacity of lithium-ion Inspiron 1545 battery, operating temperature, ID serial number, charge-discharge state, the cumulative number of charge-discharge and other important information. In the use of these data, the need to constantly refresh the actual situation. The battery built-in “chip control charge and discharge” the most important role is to monitor and control the battery charge and discharge the entire process and be documented.

Charge: Lithium-ion rechargeable battery the whole process is divided into “fast charge constant-current” and “reduced charge constant current” two stages. The so-called “constant current fast charge” means charge has just begun, the charge current and charge voltage to follow a fixed battery terminal voltage gradually increased until they reach their nominal voltage of the charging method. When the inspiron 630m battery terminal voltage has reached the standard value, the controller will automatically turn into “reduced charge constant current” phase, when the charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is rising gradually diminishing, and eventually reach zero, so they all completed a GK479 GD761 battery charging process.

At the same time, the charge generated by the process of charging voltage, current and time data curves will be recorded in the VGP-BPS8 battery’s “charge-discharge control chip” of the memory. “Battery management chip” is through access to th

ese data, calculated by the sample data such as battery capacity, which is, in Battery Information in numerical Wh read.

Fixed: After repeated charging and discharging the Dell Inspiron 1520 Battery after use, its built-in chip in the charge-discharge data will of course be changed. If at this time “battery management chip” has no chance to re-read the newer, more complete data, it calculated the battery capacity will not be accurate of course, to the user the feeling seems to be reducing the capacity of the Dell Latitude D820 Battery, and the fact that the actual capacity of the battery has not really reduced. Some bring their own brand of rechargeable laptop management software working principle, the process is in charge refresh “charge-discharge control chip” memory of the data, thus ensuring the “battery management chips,” the correctness of calculations.

A close look if you have the use of laptop manuals, will be found that “a month in the use of computer time, should make a full laptop battery charge and discharge operation” note. Its main purpose is to use the depth of charge and discharge the way to amend the charge and discharge control chip register data in the curve so that the battery charge control and battery nominal capacity and the actual situation, as a result the correct value of the battery capacity.

Nickel-metal hydride batteries will become the focus of China policy support at the present stage

January 15th, 2010

In the new energy vehicle development strategy,countries and regions all over the world have been based on their assessment of different options, they are taking a different strategy to promote support for the relevant Canon NB-2LH battery technology research and development and . From the current situation as a whole, Japan and the United States and Europe focused primarily on lithium batteries and fuel cells, but as taking into account the resources and technology maturity, in the newly released policy,China emphasis on promotion of nickel-metal hydride batteries for Kodak klic-8000 .

Although Ni-MH battery is the commercialization mainstream , but the main indicators of laboratory data are lower than lithium batteries, and for the basic theory, there is no room to improve;despite of the lithium Dell precision m series battery superior performance , but safety still can not be guaranteed, and the relatively high costs also impede their business.

Experts predict that the new energy vehicles will be in the “Ni-MH – Lithium-Ion battery – fuel cell” industry-oriented development path. From the development trend and rate, and short-term performance can be realized only nickel-hydrogen Dell precision m90 series battery , since nickel-metal hydride battery technology is the most mature in the next three years, it will remain the mainstream of new energy vehicles, followed by nickel-metal hydride battery technology and lithium iron phosphate, hydrogen fuel are cell-third of the world, 5-year lithium batteries and will be gradually replaced by fuel cells.

Battery giant Panasonic and Sanyo also found that the lithium-ion Sony NP-FP70 battery can not replace nickel-hydrogen batteries in 2 ~ 3 years, , mainly due to cheaper nickel-hydrogen battery safety,it has reached large-scale production.

According to Japan’s Fuji economic analysis, the mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion Kodak KLIC-8000battery will gradually erode the market share of the nickel-metal hydride batteries.

In our letter to the Department of Public June 25 that the “new energy automobile manufacturing companies and product access management rules” from China , the vehicle according to the new energy vehicles, systems and key assembly Nikon EN-EL3 battery technology maturity, degree of perfection of the national and industry standards, and industrial the degree of difference it will be divided into three different stages of technology maturity, and is given classified management.

Experts believe that the reason why China now focus from the development of lithium batteries into nickel-metal hydride batteries, the main reason is that nickel-metal hydridePanasonic CGA-DU21 battery technology is more mature than the lithium batteries, more abundant mineral resources, the future of new energy vehicles will enable greater access to the commercial phase.

How to reduce your Laptop working Heat

laptop-pillow

There you have it – proof positive that using a notebook computer unprotected can burn your lap and other delicate parts. So what are we to do? Stop using our Lifebook T4220 battery notebooks? I don’t think so! There are ways to have safe computing, you know. But for the 65 million or so notebook users in america, the heat hazard poses an even greater threat to their computers. Over time, the heat source that burns our lap can have an equally devastating effect on the internal components of our notebook.

So how does one have safe computing without losing intimacy with our notebook, while also protecting it from overheating? The answer is obvious – use protection. What kind? Try a Google search with the keywords “Laptop Desk” or “Lap Desk” or “Lap Tray”. There you will find all kinds of protection for both you and your notebook. We plowed through the many listings and narrowed the field to nine products that should help you practice safe computing.

But before we get to the product comparisons, let us be clear that groin burns aren’t the only hazard that notebook users are susceptible to. There are other hazards—both to the user and the Lifebook T4020 battery notebook itself—that originate from two common notebook uses: Mobile use (on your lap) and stationary use (on your desktop).

Hazards When Using a Laptop on Your Lap:

Based on research conducted by LapWorks, Inc. (www.lapworksinc.com), two-thirds of all notebook owners reported using their notebooks while mobile more often than stationary. Which means that notebook (Fujitsu FPCBP155 Fujitsu FPCBP200 ) owners prefer 2 to 1 using their notebook in their easy chair watching TV, in airline terminals, in hotel lobbies or in bed surfing the Internet, as opposed to desktop use. as we rove around using our notebooks in different ways, lap (or groin) burns are possible unless we use some form of protection.

a pillow is not a good choice. Many mobile users will sandwich a pillow between themselves and the notebook to protect their laps from “Hot Leg.” This comforts the user, but unfortunately does no favors for the Fujitsu Lifebook T4310 battery computer. The pillow acts as an insulator and contains the heat within the notebook, accelerating overheating. The notebook’s cooling fan then cycles on repeatedly ‘gasping for air’ until it shuts your computer down to protect itself from serious heat damage.

Finally, you could permanently damage your notebook with a fatal drop. a white paper study conducted by IDC (International Data Corp., a Framingham, Mass. research firm) concluded that 68% of all damage to Fujitsu Lifebook T4410 battery notebooks comes from being dropped. This includes sliding off the user’s lap and crashing to a hard and unforgiving floor. IDC further reported that in 2001, it cost businesses and industry over one billion dollars to repair broken notebooks, and replace them in some cases, totaling approximately $1,400 per incident.

Solutions to the Hazards of Lap Use:

Find a product with non-slip surfaces that spans your lap completely, can hold even the largest portable, and shields your lap from its blistering heat. Road warriors will also want something that’s lightweight, thin, and folds so it can easily fit in the computer bag.

To protect the computer from its own heat, find something with built-in ventilation channels that can actually reduce heat. You can reduce heat in two ways: convection (exchanging warm air for cool air) and conduction (transferring heat by contact from a warm surface to a cool surface). Look for products that reduce heat through convection or conduction or both as Fujitsu Lifebook T5010 battery .

Hazards When Using a Laptop on your Desk:

Strange as it may sound, the greatest risk of injuring yourself personally will most likely come when you use your notebook on a desktop over long periods of time. It is here that we risk injuring our neck and shoulders from hazards such as:

Lower than recommended viewing height of the notebook screen

Flat typing angle, or lack of incline of the notebook’s keyboard

Since most notebook computers are set flat on the desktop, their Dell Latitude D620 Battery screen heights are all below the recommended, “ergonomically correct” viewing level. This means you must strain your neck to find information at the bottom of the screen, which can lead to more serious back problems over time. The recommended height for a computer screen is positioning the top of the screen at, or slightly below, eye level. This lets your eyes do the searching, instead of having to bend and strain your neck.

another hazard comes from the Dell Latitude D630 Battery notebook’s flat keyboard. In this position, we are forced to move our elbows away from our body to get our hands in the right position to type. Supporting our arms away from our body for long periods of time eventually strains the shoulders and back so that typing becomes tiring and more stressful.

The immediate effects of neck and back strain are discomfort and reduced productivity, but medical experts agree they can lead to more permanent health problems over time.

Solutions to the Hazards of Desk Use:

Ideally, the answer is to raise the back of the Dell Inspiron 6000 Battery notebook computer to such an angle that it will:

allow natural convection (and conduction if possible) to take place under the computer, reducing heat build-up and cooling your computer.

Raise the viewing screen height closer to eye level, reducing neck strain.

Put the keyboard in an incline allowing elbows to remain by your side in a more ergonomically comfortable typing angle.

Heat is Your Laptop’s Worst Enemy:

aside from the catastrophic crash to the floor, the greatest damage to Dell Inspiron 6400 Battery notebooks comes from poor ventilation that causes overheating. Eventually, this overheating causes permanent damage, shortening your notebook’s life.

Overheating is the result of the market’s competitive demand for the thinnest form factor and greater processing power. The solution? Find a product that can actually reduce the heat by as much as 15% to 20%, which means your notebook’s cooling fan won’t cycle on as often, and your notebook computer can live a longer, healthier life!

Conclusion:

There are products that address these hazards, each to a greater or lesser degree. Keep in mind that the hazards listed above are real and documented, not just sales hype. If you are a committed Dell Inspiron E1405 Battery notebook user, you’ll want to create the safest computing environment whenever and wherever you choose to use your notebook.

Give serious consideration to the below list of nine products and select the one that best meets your specific needs. and be careful out there . . . now that groin burns have been documented, you’ll want to use Dell Inspiron 1520 Battery protection from now on so you can always practice safe computing.

Internal Storage, Battery Life, Application Sales: 3 Crucial Ingredients Android Lacks

January 12th, 2010

Android

Like a coach for a football team, these key components need rallying and coordination for Android to grow and flourish…

Internal Storage on Android has Alzheimer’s

Bottom-line, handset makers need to really consider including a significant amount of internal storage. 256 megabytes just ain’t cutting it. SD Card storage is nice to have but Android phones should have a decent internal storage capacity as the first option then SD Card second Sony VGP-BPS8. This would boost Android Gaming development if consumers could easily fit a 100MB game on the phone smoothly without clearing more than three quarters of their apps.

Battery Life is an Ankle-bitter

Partly faulted to Android’s OS and developers… background processing is a strength and fatality of the platform. Sure we love the multi-tasking capabilities but hate the strain run-away processes do to performance and VGP-BPS9 VGP-BPS9/B battery life. The Android OS by default should come with a power manager as do laptops offering; power saver, balanced and high performance battery profiles to choose from.

App Sales are Absent

Partly to blame are reasons above prohibiting superb app development and “Open Source”, which always has a confusing connotation with “free”. Even larger game development companies such as Dell WW116  Gameloft has jumped ship on Android due to lagging sales. Android app developers are squeezed to make apps at extremely low costs plus they’re selling to a smaller customer based in comparison to Apple. Another key component is until recent, there’s no way to take advantage of impulse buying such as carrier billing or “in-app” purchases.

Improving these core aspects of the platform would attract iPhone developers whom given up on Android due to key points in this article Dell XPS M1730 Battery. Overall strengthen smartphones powered by Android.

How to charge your laptop battery properly?

How to charge your laptop battery properly?

solarroll-laptop-solar-charger

During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.

For early notebook batteries as Dell XPS M1730 Battery (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.

In fact the lithium batteries has a little memory effect. The lithium VGP-BPS9/S battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.

A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had “full” level.

Sometimes WINDOWS show that ThinkPad R40 Battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery

So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity of the IBM ThinkPad R50 Battery. This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

Microcontroller Control Software Design

The key is to balance the control of the module parameters of the inspiron e1405 battery voltage collection and trigger pulse output FET and battery status to determine the control software to achieve a balanced charge and discharge at the same time should also be able to realize the battery overcharge, over discharge instructions to protect the other When the battery temperature exceeds its operating temperature range can also be a timely manner to protect the output instructions.

Experiment and result analysis

With the two lead-acid VGP-BPS8, VGP-BPS8A batteries do 12V/4Ah comparative experiments, before the experiment, respectively, the battery discharges to the voltage is not balanced, and then use the module to do a balanced two-way balanced charge and discharge experiments, test the initial conditions the same. The experimental results shown in Figure 4,5, can be seen from the diagram in the absence of a balanced case, the charge and discharge of the latter, the battery voltage difference between the more and more, while the two-way balance of modules in the process of charging and discharging effectively narrowed 2 between the VGP-BPS9, VGP-BPS9/B battery voltage, particularly in the charging and discharging the battery too late to avoid the charge and over-discharge, protect the battery pack.

In the future, PHS mobile phone charger can be universal.

“At present, the alliance has not raised objection to the implementation of standards manufacturers, so we are on schedule the implementation of the standard expressed optimism about the prospects.” Yesterday, China’s fixed and wireless terminals stakeholders Secretariat of the VGP-BPS9/S, VGP-BPS9A/B League told this newspaper.

Where is Laptop using heat come from

Where is Laptop using heat come from

logitech-notebook-riser-n110

The article first post in http://batteryblog.info

We are using the notebook for some time. Weoften found that notebook slowly get hot after using for a while, especially the bottom of laptop. The situation occur frequently in Summer. Where is laptop using heat come from?

When the machine overheating, some harm reasult happend: laptop system halted, restart, and even laptop parts burn (espacilly laptop battery). Which laptop part produce such a large amount of heat? Here I will give us a presentation.

As the desktop CPU’s power consumption and heat is very large. It can not be used in notebook as Dell WW116 , so mobile processors is specifically designed for notebook. Many notebook CPU processor power consumption are over 20W, particularly in the mobile Pentium 4 processor. Though there are a lot of technology tips make notebook average energy consumption low, but the peak is still very high (more than 30W) when using. Many of these energy consumed will come into heat dissipation. Therefore we should always check the clearance of xps m1730 battery CPU fan air vents. Make sure there are no stolen goods block the air vents, that cause the heat can not dissipate. If the notebook CUP silicone hardening, we should replace it in time.

First, the XPS M1530 Battery notebook cooling heat is mainly come from the CPU working heat. But CPU heat is not the all. And the early CPU processor heat is not very large. Just use some simple passive cooling method that can satisfy the cooling needs of the machine. That is the heat sink cooling as we usually known. However, as the continuing escalation of CPU processors, while in the Pentium processor century, the processor’s cooling is the big problem.

Secondly, the graphics card heat is also a large proportion. Early graphics cards heat is not large, but now a lot of high-end machines such as Inspiron E1505 Battery Inspiron E1705 Battery often configure the ATI Mobility Radeon HD4750 or GeForce GT240M such a good graphics card, so the heat also increase a lot.

Finally, there is some other hot parts, such as memory, hard drives, laptop battery, are also a number of laptop heat source.
