How Does Lenovo Laptop Battery Work

Dec 29

Posted by admin in battery info | Comments off

A laptop battery works in much the same way as batteries that go into portable CD players, remote controls, and shower radios. Just like the batteries used in these household items, laptop batteries come in different sizes based upon the size of the laptop. Laptop batteries however, contain within them complex charging circuitry that works together with a laptop’s hardware.

Inside each laptop battery are internal power cells. These power cells are arranged in a series and are parallel to each other. This is done in order to maximize the voltage level for the lenovo battery as a whole. In addition these cells are controlled by a circuit board. The circuit board regulates how the cells work for both the process of discharging and recharging energy. It makes sure that your battery is not overcharged when charging, and it makes sure that each cell drains the same amount so you can have a longer run time.

Inside each battery there are also positive and negative electrodes. In order to power your laptop, a chemical reaction occurs with both the positive and negative electrodes. This reaction flows in a specific way in order to discharge energy. Plugging in your adapter reverses this process in order to recharge your thinkpad t60 battery. The process of reversing the chemical reaction occurs for both positive and negative electrodes. To make both the discharge of energy as well as recharge process work, this process must be exact. If not, then a short-circuit may occur. This process is basically the same whether your battery runs on Lithium Ion (Li-Ion), Nickel Metal Hydride (Ni-MH), or Lithium Polymer (Li-Poly).

This process is then regulated by hardware within your laptop. The hardware in your laptop ensures that the cells are functioning to their capacity. This is what also allows you to check the life left on your thinkpad t60 battery before it needs to be recharged. A battery symbol is typically displayed on the right corner of your task bar. This symbol graphically shows how much energy has been discharged as well as how much is left.

Although a laptop battery is rechargeable, it does have a limited life span. A typical battery usually lasts for about 500-700 charges before it will no longer be capable of recharging, and a replacement is necessary. The amount of charges can vary depending on the main use of your laptop. Some functions require more energy then others. Using functions such as a DVD player or using the brigh test screen setting can drain the battery quicker, thus requiring it to be charged sooner. The more often you need to charge your thinkpad t61 battery, the sooner the battery will be drained of its life span.

Manufacturers will additionally custom tailor their laptop batteries based upon the needs of each laptop model. A few things that impact the appearance of a battery are the overall size and weight of a laptop. After all, a small notebook would be difficult to carry if the battery weighed an additional two pounds. These factors account for their varying sizes. One size does not fit all in the world of laptop manufacturing. Overall functionality is the key.

Waste Heat Could Double Battery Life on Laptops

Dec 7

Posted by admin in battery info | Comments off

If this wasted energy is cleverly harnessed we might double the use of cell phones talk time without plugging them again and again for recharging. The same could be the case with our laptops; we don’t have to recharge lenovo battery frequently and their wear and tear could be reduced too. The overworked and overloaded poor power plants can shell out more power if their wasted heat energy can be utilized.

Hagelstein is of the view that current solid-state devices that utilize excessive heat and convert it into electricity are not very efficient. He is working with his graduate student Dennis Wu as part of his doctoral thesis to find out a practically dependable heat energy converter that doesn’t carry forward its predecessor’s disadvantages. They are gunning for a realistic technology that could come to achieving the theoretical limits for the efficiency of such conversion,lithium-ion batteries,thinkpad t60 battery,thinkpad t61 battery.

Theory postulates that such energy conversion can never go over a precise value called the Carnot Limit. Carnot Limit was established in 19th-century. It is a formula for determining the utmost efficiency that any machine can achieve in converting heat into work. But the fact is in practice we have only achieved about one-tenth of that limit. Hagelstein working in close association with Yan Kucherov carried out experiments by going for a different technology. They have achieved the enviable efficiency as high as 40 percent of the Carnot Limit. Moreover, their statistics exhibit that this new kind of system could ultimately reach as much as 90 percent of that ceiling.

Hagelstein, Wu and others didn’t try to improve upon existing devices. They started afresh without any past baggage. They make use of a very simple system in which power was generated by a single quantum-dot device. That device is a type of semiconductor in which the electrons and holes are very securely restricted in all three dimensions. So they tried to understand all the features of the device. This helped them in understanding better all the aspect of such machine.

Hagelstein says that he doesn’t merely want to convert heat into energy but he wants to achieve this by getting lots of energy in return. He also admits that current technology is available to harness heat power, but with a catch. It is known as high-throughput power to thinkpad t60 battery. It converts heat from a less efficient system and you get more energy. But this is larger and more expensive system. According to Hagelstein “It’s a tradeoff. You either get high efficiency or high throughput.” But the team found that using their new system, it would be possible to get both at once.

Hagelstein and his team studied a recent paper published by MIT professor Gang Chen carefully. They talked about lessening the gaps between hot surface and the conversion device. They suggested this arrangement as very crucial for improving the output. Gang Chen claimed that heat transfer could take place between very closely spaced surfaces at a rate that is orders of magnitude higher than predicted by theory. The new report admits going a step further that heat can not only be transferred, but converted into electricity so that it can be harnessed.

Robert DiMatteo heads a company, MTPV Corp. (for Micron-gap Thermal Photo-Voltaics). DiMatteo is willing to commercialize Hagelstein’s new idea. He is quite hopeful that the technology developed by his company could yield a tenfold improvement in output power over existing photovoltaic devices. He plans to market this technology next year. At the same time Hagelstein’s work would give the required push and an additional tenfold or greater improvement is possible.In onther words,laptop battery will be a stronger power.People will get better thinkpad t60 battery,thinkpad t61 battery,thinkpad x40 battery.

DiMatteo presents his stats and says that worldwide, when we consume fuel or a powerhouse generates electricity nearly 60 percent of all the energy is wasted. This waste is generally in the form of heat. 60% is substantial amount. DiMatteo is now hopeful that this technology could “make it possible to reclaim a significant fraction of that wasted energy.”

Hagelstein is of the opinion, “There’s a gold mine in waste heat, if you could convert it. A lot of heat is generated to go places, and a lot is lost. If you could recover that, your transportation technology is going to work better.”

Temperature characteristics: When the rechargeable battery in the electrolyte and the electrode body rate of migration of film and temperature are closely related, if the temperature fluctuations significantly influence the technical performance of rechargeable batteries.

Storage temperature: Under normal circumstances, the thinkpad t60 battery due to internal fluid, and low temperature will destroy the long-term storage of chemicals inside the battery, it is proposed conditional case, the temperature Storage is not lower than -20 ℃, while the high temperature also the battery can not achieve its rated capacity, the storage temperature generally not exceeding 40 ℃. Normal storage temperature of the rechargeable battery of -20 ℃ ~ 65 ℃ when the temperature dropped below -20 ℃, the battery will be consolidated into the electrolyte, the internal resistance of the battery becomes infinite, the battery will not be available. When the temperature exceeds 65 ℃, the electrolyte side reactions occur which produce large quantities of gas, electrode deterioration of the film adhesive resin can occur, causing the entire cell aging and declining, even short-term break.

Charging temperature: In general, accusing a temperature of 0 ℃ ~ 45 ℃. Discharge temperature: In general, the discharge temperature of -20 ℃ ~ 65 ℃, but in some cases, can use batteries at low temperature and high temperature thinkpad t60 battery. Battery before leaving the treatment plant after a general discharge, to prevent the transit due to vibration or other causes of short circuit, usually a new battery is not charged or containing only about 20% of electricity. A new battery or long-term unused because the battery may not fully activate the active substance before use usually takes two or three cycles through the small streams (0.1C) charge and waste treatment, in order to reach the rated capacity. A long time not to use the state of the battery must be stored and can be pre-filled 50% to 100% of electricity after storage, has proposed to charge the battery once every three months to restore the capacity of saturation.

Battery Caution: 1.Do not incinerates or disassembles the lenovo battery, in which chemicals are corrosive, will damage the skin and eyes. 2. Do not pull on the drum tracks or connectors; solder joints, and joints to prevent injuries. 3. Different types of batteries can not be mixed. 4.

Maximizing Lenovo Battery life

Nov 23

Posted by admin in battery info | Comments off

I’ve gone and done a lot of experimenting and have a list of my tips to really maximize lenovo battery life for my laptop.

1.Brightness: how low can you go? Without any question, the fastest way to suck the life out of a thinkpad x40 battery is leaving your brightness high. Turn it down as low as you possibly can without needing to up your glasses prescription. On my Vaio, I can select from one of 8 levels. During one test, at brightness level 3 my system reported 60% full, with 3:52 (all times are hours:minutes) of life to go. I switched up to level 5 and in 17 minutes of use, I was down to 52% full, with 3:06 to go. In other words, 17 minutes used 46 minutes worth of battery (all other variables were held constant). You can even be so bold as to lower your brightness all the way down when sitting idle for a minute or two (for example, if you are writing a long blog post and pause to clarify your thoughts before typing).

2.Don’t use any external devices. USB and PC-Cards (aka PC-MCIA) use your thinkpad t400 battery to function, even when you aren’t using them! Have an EVDO card or maybe a USB mouse? Remove them if you can. Even a memory card reader in your PC-MCIA slot uses power just by being in there. The effect varies based on the type of device, but even a few minutes here and there (as you’ll see) add up significantly.

3.Single-task, not multi-task. The more you are doing at the same time with your PC, the more memory and CPU usage increases. Both of which directly use up thinkpad x41 battery. Close any applications you aren’t using, even the small ones. When doing some experimentation, I found it more efficient to run a single application at a time, then close it and open a new one when ready to move on. While your hard drive uses the battery too, if you are doing anything ‘productive’ you are probably hitting the drive on a regular (even if infrequent) basis anyway.

4.Keep it cool. You can take a page out of the extreme gamer’s handbooks, and have your system perform more optimally by keeping it cool. Make sure your air vents (inflow and outflow) aren’t blocked by anything, which often occurs by poorly positioning your notebook on your lap (which is known to have some other side-effects too, by the way). Heavy CPU and memory use all contribute to heat as well, hence my comment on multi-tasking above.

5.Shut down unused services. MSN Messenger, Google Desktop Search, QuickTime, wireless managers, etc. They’ve all gotta go. You probably aren’t going to use them, and they all eat up valuable resources. Especially things that ’scan’ anything. For advanced users, I also recommend launching Windows Task Manager and getting rid of anything not used in-flight. In fact, I put together another little text file with a list of all the services I don’t use, and I go down the list and manually shut down each one. If you really want to get this one right, a little bit of research is in order. While online, I launched the task manager (control-shift-escape) and for each service that has my User Name, I googled it. There are a few good web sites out there which chronicle what all these mysterious services do, and you should be able to figure out which you need, and which you don’t. Important warning: if you aren’t comfortable with this lingo, you should skip this step, or get some techie friend to help you out. Less important warning: you may end up in a situation where you need to do a reboot after you get to your destination.

6.Do Hibernate, Do Not Suspend. I’ve found that my Vaio tends to use way too much lenovo thinkpad t400 battery when in suspend mode. Not sure why, but the ‘instant-on’ effect isn’t worth the extra 30-60 seconds it takes to get out of hibernation. Furthermore, the minor hit to the hard drive is unlikely to have a significant impact to your overall battery time. Also, if you weren’t aware, going in and out of hibernate is much better than a full startup/shutdown sequence. Note that you might need to manually enable Hibernate as a system option (once you have, the quick shortcut into it is ‘windows button’ followed by U followed by H, and some PCs will have even faster shortcuts available as well). If you make a run to the bathroom, however, that’s worth a quick Standby, but anything over 10 minutes and I’d Hibernate instead.

7.Tweak advanced settings. Virtually all laptops manufactured in the past 24 months have some advanced power options. Mine, for example, allows me to go into 16-bit color mode, force the CPU into a power-saving mode, disable my LAN port, and more. This might seem obvious, but if you aren’t doing it already, go find these settings (probably in the control panel, or possibly through custom software provided by your manufacturer) and get aggressive with them! If you don’t have any extra control, one good extra tip is to manually force your screen into lower color modes, as they use less CPU overall and can make a huge difference in the long run. While you are at it, you might want to change your Alarms settings, as many laptops default to shutting down with as much as 10% of your thinkpad x41 battery still available (my Low Battery is just an alert at 5%, and my Critical is force hibernate at 1%)!

8.Choose Wisely. Good: Word, Excel, Outlook, Text Editors. Bad: anything by Adobe (you think Microsoft has bloatware, have you noticed how long even Acrobat takes to launch these days???), all Google plugins, many ‘Widgets’, ‘Gadgets’, etc. All I can say is pick your battles wisely. 50 minutes of a video game ate up over 2 hours of my lenovo laptop battery time, whereas writing email or documents tend to use up less than what Windows predicts (about 105% of the estimate on average). I’ve also found WinDVD is right on the money for battery consumption, and Windows Media Player is a little power-hungry (by the way, if you are using your laptop to play music make certain you disable visualizations). On that note, don’t use your laptop to play music unless absolutely necessary, it’s a real resource killer.

9.Watch That Hard Drive. I just wrote, don’t play music, but the reason is mostly about your drive. The more it spins, the more power it takes. Make sure you’ve set your basic power option to turn off your drive relatively fast, but not necessarily too fast. Some drives use more power getting started than staying running for short periods of time. I set my Vaio to turn off the disk after 3 minutes of inactivity, you may want more, you may want less. At the end of the day, if you are doing anything that prevents the hard drive from spinning down ever, you are draining your thinkpad T60 battery more than needed.

10.Like a Boy Scout, Be Prepared. I make a point of configuring my ‘flight mode’ prior to getting on the plane. It may only take 5-10 minutes to get your system setup properly, but that just eats into your battery life if you wait to do it on the plane. Once done with all the settings, the last thing I do before unplugging my power supply is hibernating the PC.

I hope some of these tips help you out. Personally, I add around 30 minutes (or more) to the longevity of my standard battery (3:30 on average now), and almost an hour on the extended one (6:30 or so). This gives me almost 10 hours of combined life (4 full DVDs guaranteed), which suits me quite well.

    Li-ion battery industry ready

    Sep 30

    Posted by admin in Uncategorized | Comments off

    July 1, begin to carry out-new energy automobile manufacturing companies and product access management rules,” which states that “the use of lead-acid battery hybrid passenger cars, pure electric and pure electric passenger cars, commercial vehicles, and the use of metal hydride Nickel-powered hybrid vehicle is classified as mature products. “Prior to the loudest voices were included in the lithium cell vehicle development stage, not a large-scale promotion of the column.

    Conducted in Frankfurt, Germany Frankfurt auto show in order to Daimler – Benz, Volkswagen, Toyota car dealer, represented expressed their optimistic about the development of lithium batteries, and a series of Li-ion laptop battery pack equipped with the hybrid to reduce vehicle carbon emissions. Such as the Toyota van in carbon emissions of a mere 60 g / km (average annual emissions from ordinary cars 5000 kilograms).

    Then prospects for lithium batteries in the end?

    New energy electric car the most important components is the driving force batteries(gd761,kd476), electric motors and energy conversion control system. The new energy vehicles demanding on the battery, you must have a high specific energy, high specific power, fast charging and deep discharge performance, and requires the lowest possible cost, service life as long as possible. Therefore, the power battery is a technical threshold of the highest, is also the most concentrated part of the profits.

    Lithium batteries into the fast-growth period

    More auto manufacturers choose lithium batteries as a new energy vehicles motive power, industrial output value contains huge potential.

    The traditional lead-acid batteries, nickel-cadmium batteries and nickel-metal hydride battery technology itself is relatively mature, but they are used in automotive batteries as a power, there are still major problems. Li-ion battery(VGP-BPS2C,VGP-BPS2A) has a small size, light weight, high voltage (which is nickel-cadmium batteries, nickel-hydrogen batteries 3 times) than the energy of large (up to 165WH / kg, nickel-hydrogen batteries 3 times), cyclic long-lived, self – discharge rate is low, no memory effect, no pollution, safety, and good, therefore, car manufacturers more choices of energy use lithium batteries as a new car battery power.

    China’s lithium-ion battery industry began late in Japan, but developing very fast in recent years, especially in the power lithium-ion battery(inspiron e1705 battery,xps m1330 battery) research and development invested a great deal of financial and material resources. China’s automotive lithium-ion battery R & D project has been the national “863″ key project, much of the material to achieve the localization and the introduction of multi-national has been self-built production lines and supporting materials, factories have more than one, have been the formation of large-scale production, intense market competition.

    Lithium battery industry as car tremendous value inherent potential of electric vehicles battery materials upstream suppliers and downstream of the car manufacturers have begun to enter the automotive battery business. Li-ion battery is behind the hot car prices on the plug-in hybrids (also known as plug-in hybrid electric vehicles) and pure electric vehicle market prospects of the recognition and R & D capabilities of their current concerns.

    Such as the United States Ford, Toyota, Mitsubishi, Nissan, Hyundai, France, Courreges, Ventury and other companies have started their own lithium battery Motor Vehicle Program. While the domestic car manufacturer BYD, Geely, Chery, Lifan, ZTE and other car firms also have their own hybrid and pure electric vehicle powered by lithium battery power.

    Therefore, from the development cycle, the current automotive lithium battery market is out of the start-up stage and started into rapid growth stage.

    Insufficient to resolve the charge and over-discharge phenomena

    safety performance and vehicle power battery management system is the bottleneck of the development of lithium batteries.

    At present, the downstream enterprises in China BYD, Wanxiang Group, Shenzhen BAK Battery, Tianjin Lishen Battery and the United States Myers joint ventures. At present the only control vehicle lithium ion phosphate battery pack(inspiron b120 battery,inspiron b130 battery) large-scale production technology, BYD Company, has officially launched its self-developed battery-powered pure electric vehicles E6 and hybrid F3DM.
    , However, hinder the development of lithium-ion battery power bottlenecks are: safety performance and vehicle power battery management system.

    Automobile manufacturers based on the safety of people-oriented concept, the safety of the battery presented a very high demand. As the vehicle power battery voltage is 12V or 24V, single power lithium-ion battery voltage is 3.7V, so must be used by multiple cells in series, but difficult to achieve because of the battery charge and discharge completely homogeneous, resulting in the battery charge will appear Discharge imbalance, which occurs under charging and over-discharge phenomenon, the situation will lead to a sharp deterioration in battery performance, eventually leading to the entire group of cells does not work, or even scrapped, greatly affect battery life and reliability.

    Therefore, power lithium-ion battery to get a good application, need materials, batteries, management systems, taking into account the mechanical processing and other aspects. Therefore, the upstream and downstream enterprises should work together to the battery as the core of the material, the management system requests formation of an industry group, would be conducive to technological advances and system costs.

    Midstream materials manufacturers continue to realize the localization and improvement of technical

    Cathode materials for lithium battery(gd761,kd476) is high barriers to entry, capacity minimum; anode materials for the industrialization of China has been achieved; electrolysis fluid and membrane technology is still dependent on imports.

    Lithium battery materials can be divided into electrode (positive / negative) materials, separator and electrolyte. Li-ion battery cathode material is the core of the current lithium cobalt oxide, lithium manganese, lithium and nickel-cobalt-manganese-based lithium ion phosphate. Ze Yi graphite anode material, solid carbon particle-based; in the middle of positive and negative electrodes while the battery electrolyte and separator.

    As high barriers to entry, lithium battery cathode material is the smallest capacity, which is the whole industry chain, the most promising aspect. Cathode materials currently in production companies are: China Baoan, CITIC Anhe Shanshangufen, BYD.

    Compared with the cathode materials, anode materials, graphite, solid carbon particle, accounting for the proportion of low-cost lithium batteries(inspiron e1505 battery,inspiron 6000 battery), and the domestic has been achieved industrialization. Currently engaged in lithium battery cathode material production enterprises are the top three Chinese national security, Shanshangufen long shahai capacity. It is worth noting that the current negative electrode materials, while able to basically meet the domestic market demand, but with the increasing popularity of new energy vehicles in future this demand will be a massive shortfall.

    Domestic battery manufacturers supporting electrolyte has been basically achieved domestically. The electrolyte lithium hexafluorophosphate main raw materials, accounting for about 50% of the cost of the electrolyte, its production cost is 10 yuan / ton, priced at 40 yuan / ton, gross margin as high as 75%, but the market was largely Kanto Electric the chemical industry, SUTERAKEMI-FA, Morita chemistry, several Japanese companies a monopoly.

    Diaphragm materials, the Department of Li-ion technology, the highest barriers to a high value-added material, gross profit margin is usually 70% or more, accounting for the cost of lithium batteries 20 ~ 30%. It is reported that a car need to 1000-2000 m2 membrane. At present, a serious shortage of market supply diaphragm, most dependent on imports, the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard dominate. Domestic companies able to produce membrane only star-source technology, Jinhui High-Tech two technologies are relatively mature.

    Upstream resources and technical barriers to seek a breakthrough in

    lithium ion phosphate power battery(thinkpad t60 battery) cathode materials, the most promising investment opportunities, but the reserves are limited; simultaneous separation of lithium carbonate in Technology is only a small number of the hands of foreign companies.

    Lithium ion phosphate power battery cathode materials, the most promising investment opportunities, the key raw materials, lithium iron phosphate is lithium carbonate, lithium carbonate derived from the mineral resources, in the nature reserves are limited, has a strong regional and scarcity, are scarce resources. Thus, in the new energy automotive industry chain, the strategic importance of lithium carbonate resources become particularly prominent.

    At present, the global lithium carbonate industry, the status quo, resource threshold high, capacity is highly concentrated. As of the end of 2007, a major international manufacturers have Chile’s SQM, the United States, FMC and Germany Chemta l l total annual capacity of 78,000 tons, accounting for 80% of global market share. Due to large-scale production enterprise must have reserves of lithium resources are more abundant in salt lake resources, mining rights, making the resources of the industry with higher barriers to entry; the other hand, the vast majority of the world’s resources are high-magnesium salt low lithium type, from the and high-magnesium low lithium brine purification separation of lithium carbonate in the process technology is very difficult, but these techniques only a small number of foreign companies rests in the hands, so the industry is highly technical barriers.

    The current domestic production of lithium carbonate enterprises mainly in Tibet, mining, CITIC Guoan, Western Mining Group, Qinghai Salt Lake Group, the four companies, while the Tibetan mining and CITIC Guoan has accounted for the vast majority of , the two companies in 2008 total production of lithium carbonate is not more than 4000 tons.

    It is estimated that each new type of electric vehicle needs about 0.08 tons of lithium carbonate, lithium batteries(xps m1330 battery,latitude d830 battery) once the driving force large-scale application of new energy vehicles, only new energy vehicles by 2012 the demand for lithium carbonate will reach 5 million tons. While the domestic prices of industrial-grade lithium carbonate at 4.5 yuan / ton, battery grade lithium carbonate prices by 7 yuan / ton, high purity lithium carbonate price is as high as 10 yuan / ton, the domestic involved in new projects because it is used salt lake brine lithium carbonate extraction, the production cost 10000 ~ 1.5 yuan / tons. Therefore, the market generally felt that the profitability of lithium carbonate products is very high
