Digital battery

1 Introduction As people's living standards improved, rechargeable batteries, especially large current batteries (lead-acid batteries, nickel cadmium and nickel-metal hydride battery) in the power sector, railways, the military has achieved an increasing number of applications, however, battery can be No reliable electricity, and achieve the required plant life, with the battery charge-discharge routine maintenance and management correct or not is closely related. As is now widely used batteries are not with intelligent detection devices, that is, digital batteries, so battery charge and discharge current size, the size of the terminal voltage, charge and discharge time, charge and discharge frequency, charge-discharge capacity, remaining capacity, battery internal temperature and life and other basic parameters, can only rely on manual measurements or roughly estimated that the event of errors, will be our normal production and lives of unpredictable consequences, as well as the electrical performance and life of battery and causing irreparable damage.

With the development of microprocessor technology, mobile electronic devices function on its own in terms of developing very fast, at present the vast majority of digital, intelligent, internal control circuit more or less completed by the CPU chip. But it is part of the power supply is extremely primitive, under normal circumstances is only one Asus Laptop Battery such as Asus A42-A3 Battery of the DC to the electronic equipment, while the battery's own characteristics, status and other parameters are unable to provide electronic devices that can not be related to the electronic equipment data communications. This intelligent electronic devices increase, bringing new problems.

If the battery of various state parameters can be stored by the microprocessor, recording, analysis, control, printing and display, intuitive to provide to the relevant personnel, and to achieve and related electronic equipment for data communications, that is, digital technology, which not only can to reduce human error and extend battery life, but also be able to achieve related to intelligent control and electronic equipment unattended. Therefore, the battery of digital research and development is a significant issue.

2 The concept of Digital Camera Battery

The exact definition of the digital battery is still not harmonized. This concept comes from the rapid development of information industry, which mainly come from the world's leading notebook computer design, production and suppliers. In practice, once the battery is dead when the key is bound to produce unpredictable losses, digital camera batteries idea is put forward in this case, with it, we will be able to grasp the battery status of work on the can be prepared in advance and timely replacement. The working conditions are talking about here should include the following aspects:

(1) the current size of the battery terminal voltage, charge and discharge current size, charge and discharge time;

(2) Current battery impedance, remaining capacity, the remaining charge and discharge time, the battery temperature;

(3) the current battery charge and discharge times, life.

In the actual development, the researchers found that only about the work of the battery status and does not meet our battery requirements, also need batteries to electronic devices and related data transmission, in order to achieve the battery switch, automatic battery charging and so on.

Clear from the foregoing: the so-called digital battery, which contains an ordinary rechargeable Canon Digital Camera Battery such as canon NB-1L battery, canon NB-2L battery, canon BP-511 battery, canon NB-5L battery, canon NB-4L battery, canon NB-5H battery, a digital battery control module, as well as the communication interface, complete the battery of the digital measurement and control management and data communication capabilities. In addition to the above-mentioned working conditions in digital form accurate visual display (or provide), but also to provide background information and identity of the battery data (such as battery manufacture date, manufacturer data, etc.); in the process of charging with the corresponding alarm protection measures (such as over-voltage protection, over-temperature alarm, etc.); same time, it should be consistent with some kind of communication protocols (such as system management bus, SMBus), has the host, intelligent charge controller such as communications interfaces, capable of information transmission and control. Schematic diagram of digital batteries are as follows:

3 Digital value of the battery status and development

Digital battery first started to develop from abroad. As early as 1995, the U.S. military have been digitized battery equipped troops, but these batteries are not highly digitized, versatility is not strong. According to online information-gathering that is limited, and foreign research and development of digital batteries by rechargeable batteries, control modules, of which control module of the software components should be consistent with the specific communication protocol. Posed by the digital battery digital battery system hardware includes: System console, digital battery (which can be one, it can be a number of pieces), intelligent charge controllers, AC / DC converter and transmit data bus network. Software, including the transmission of data communication protocols, data processing platforms and embedded operating system and the corresponding procedures. There are many foreign companies and enterprises to participate in research and development of digital battery, Intel Corporation and co-production of digital Duracell batteries, this product called PowerSmart, in line with SBS (Smart Battery System) standard. Motorola is also developing be broad user acceptance of digital batteries. Germany's giant Varta batteries and Duracell companies are developing a new generation of digital batteries, this battery will soon be available.

From the battery industry in the tenth Five-Year Plan was informed that the United States, Japan and Europe accounted for 70% of the global battery market. Consumption of the battery, the United States per capita reached 25 / person; Japan's annual per capita reached 20 / person. While China's annual per capita consumption of less than 7 cells. Therefore, the battery in China, a great market. China's battery industry focused on the mercury-free alkaline manganese batteries, Ni-MH power batteries, lithium-ion batteries, sealed maintenance-free lead-acid batteries, vehicle power batteries, fuel cells, solar cells in the development and production. In the army, the secondary battery, such as cadmium, nickel, nickel-hydrogen battery in a large number of equipment use, military research and development of lithium-ion batteries are also soon will be equipped with troops in the next period of time, there will be three kinds of batteries coexistence phenomenon.Therefore, secondary batteries in our digital, has great space for development. Meanwhile, the secondary battery digitized, people using battery-powered digital time, and will not in the normal work of a sudden power- down and affecting their work and a certain amount of loss; can be more scientific and reasonable or that the use of batteries, the battery will not be over-discharge and over-charge, can effectively extend battery life; accurately display battery data and provide data to the host can be an effective state of the battery each corresponding control and processing; on the battery aging will also be the final warning prompt ; Therefore, the corresponding cells have a breaking capacity of Jane; constitutes a digital cell system can be used to remotely monitor the battery and the use of reliable data for efficient energy management. Thus, digital battery also has a high application value.

A Better Gauge on Battery Life

Texas Instruments (TI), based in Dallas, has developed a battery-gauge chip that can tell mobile-phone users down to the minute how much talking or standby time they have left--a degree of accuracy much greater than that provided by existing battery gauges. Such a precise gauge could allow smart-phone developers to squeeze more energy out of the battery, potentially increasing by half or more the amount of time that it lasts between charges.

The new TI gauge is more accurate than today's gauges, which measure a battery's voltage, because it measures a number of electrical properties. Voltage-only-based gauges are erratic and unreliable because voltage doesn't fall steadily as the battery is discharged. What's more, the voltage changes as the battery ages and experiences different temperatures. It also varies with different power demands on the battery such as Acer TravelMate 290 Battery, Acer TravelMate 4000 Battery, Acer TravelMate 2300 Battery, Acer Aspire 1680 Battery, Acer Aspire 1410 Battery, Acer TravelMate 4500 Battery, Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, Acer BATCL32 battery and Acer BATCL32L battery.

The TI gauge is more accurate--to within 1 percent of the actual energy left in the battery--because it measures electrical properties besides voltage. Most important, it measures a feature of battery cells that is at the root of the voltage changes that make today's gauges unreliable. This feature, called impedance, is a measure of the opposition to current flow, and it changes with temperature, battery age, and the power demands on a battery.

Knowing the changes in impedance allows the chip to reinterpret voltage changes, keeping it from being fooled by voltage changes caused by these factors. For example, when a person makes a call, the voltage drops as soon as the phone transmits the signal. A conventional gauge would interpret this as a sudden drop in the amount of energy left in the battery, which could engage battery-saving measures in power-management software. The new gauge would recognize that the cell still has plenty of energy. The approach also works with low voltages caused by cell age.

The new gauge chip, which is incorporated either into the circuit boards of a phone or directly into a battery pack, could be particularly useful in smart phones. Some phone users have to assume that after the gauge has reached the halfway point, the battery could die at any moment. What's more, poor battery gauges make it difficult to employ power-management software on phones that could extend battery capacity. Power-management software slows down processors, turns off the camera's flash, and dims the screen to save the battery once it's low. It may also save data and shut down applications just before the battery dies. Such software, however, may engage power-saving measures too soon if it relies on an inaccurate battery gauge, resulting in sluggish device performance while there is still plenty of charge.

The problem gets worse as the battery ages and, as the battery is depleted, voltage drops more quickly. With conventional gauges, this could trigger the phone to shut down when there is still quite a bit of energy left. Indeed, much of the perceived loss in battery life in older phones is actually just a problem with the battery gauge. "You can lose 30 percent of the energy in a battery simply because the device shuts itself down too early," says Richard DelRossi, an engineer at TI. He says that the new, more accurate battery gauge could increase the usable battery capacity by as much as 50 to 100 percent, depending on the power-management strategy.

Other phone and chip makers are also developing better battery gauges. Approaches taken by Motorola, based in Schaumburg, IL, and PowerPrecise, a chip maker based in Herndon, VA, that's funded by Intel, combine voltage data with current measurements to determine how much energy has been used. Subtracting the amount of energy used can give a good idea of how much is left, as long as it's known how much energy was there to start with. But the capacity of the battery, as with the voltage, depends on certain conditions, such as temperature, battery age, and power demand. To adjust for these factors, these systems can refer to models of battery behavior based on earlier tests to guess how these conditions will affect the battery's overall capacity. Such a system gives a much more accurate gauge of battery charge than do voltage measurements alone, says Jerry Hallmark, who heads Motorola's research on energy consumption in mobile devices.

Google Unveils First Chrome OS Computer

One way to summarize Google's week so far is to say that it picked fights with two of the biggest computing companies on the planet. On Monday it unveiled a bookstore that competes with Amazon's Kindle line. Today it took the wraps off an attempt to displace Microsoft from the provider of the most popular operating system.

"With Chrome OS we have a viable third choice for OS on the desktop," said CEO Eric Schmidt at the launch event in San Francisco, drawing a comparison with Windows and Mac OS. He spoke after a lengthy demonstration that showed off a new vision of the computer that strips away pretty much everything except the browser.

Fresh out of the box, a Chrome notebook boots up in a few seconds. After connecting it to the Internet, you log in with a Google account and are pitched into the Chrome browser. At that point, the setup is over. Chrome OS is little more than Chrome the browser.

In this new world you get all your applications through the Chrome webstore, an app store on the now familiar model (check this link later today to browse the Chrome Web store using the browser on an existing OS). You can browse, search, read reviews and click to install. Some are paid and some are free. Examples shown today included a version of EA's puzzle game PopIt, a tablet-style NPR app that lets you drag and drop shows to build a custom playlist, and one from the New York Times that lets you choose alternative "skins" for the paper's content.

Those apps can be powerful because of features built into Chrome that make it faster than any other browser, boasted Sundar Pichai, vice president of product management at Google. Many—including most games and the app from the New York Times—can also work offline because they are cached by the browser, a feature that will soon appear in Google's online Microsoft Office competitor, Google Docs.

It adds up to an experience that looks compellingly simple. "Since 2004 it is very hard to name a new application outside the Web that has scaled to hundreds of millions of users," said Pichai, "people live within their browsers on the Web but most of the code and complexity on their systems has nothing to do with the browser and the Web." Chrome OS strips all that away, even updating itself without user input.

Very soon, certain users of the Chrome browser and fans of it on Facebook will get the chance to try that for themselves when they are invited to join a pilot program. They'll receive a notebook commissioned by Google to test its new OS. Notebooks made by Acer and Samsung—built with Intel chips—will go on sale globally in mid 2011, although pricing hasn't been announced. All of those devices will see battery such as Acer BTP-42C1 Battery, acer BTP-44A3 Battery, Acer BTP-550P Battery, Acer BTP-73E1 Battery, Acer BATCL50L Battery, Acer TravelMate 290 Battery, Acer TravelMate 4000 Battery, Acer TravelMate 2300 Battery, Acer Aspire 1680 Battery, Acer Aspire 1410 Battery, Acer TravelMate 4500 Battery, Acer LCBTP03003 Battery and Acer Aspire 1300 Battery lives in the region of eight hours while in active use, and weeks on standby.

It's possible to overdose on simplicity, though, as evidenced by some things Chrome OS currently lacks. A "Cloud Print" service that will allow use of network-connected printers is not yet done, for example, and although the devices will have USB ports it is not yet possible to plug in, say, a camera and download photos.

Building Chrome was not just an exercise in subtracting from the conventional OS experience, though. It also introduces some technologies not seen before. One is a feature called verified boot, which sees the initial chunk of the OS installed on a part of the device that cannot be modified without physically taking the computer apart. "Every time you boot we use that safe part to cryptographically check every other part of the OS and we keep a known backup copy that we can revert to," said Pichai. "We are very confident that it will be the most secure consumer OS shipped."

Ultimately, though the core promise of Chrome OS is familiar: it's an attempt to deliver on a suite of ideas and concepts about cloud computing and the Web that have been circling for years. Schmidt in particular has been here before. In the late 90s, in a previous life as CTO of Sun Microsystems, he pushed the "Network Computer," a diskless notebook that relied on the cloud for everything. "Our instincts were right 20 years ago but our technology wasn't mature," he said today. "This time it does in fact work."

Acer Aspire One Model

Acer Aspire One Model

The netbook received for writing the first test of the Aspire One is in its basic version: 8GB storage, 512 MB RAM and Linpus Linux OS. Very compact and lightweight product that competes with the Eee PC is positioned between the media player and computer ultraportable. For this article, we will deviate from the usual structure of laptops. The goal is not to measure the performance of the machine.

It is easy to verify that it is possible to do (in good condition) with a device of this type and to identify its strengths and weaknesses. Ergonomics. As outlined in box, the entire laptop is not glossy (shiny), which is good news. Only the back of the screen and around it fall into this trap, said aesthetics, but also a source of countless fingerprints. The whole apparatus is, of course, very compact and space loss is not tolerated. The keyboard is in pretty much identical in size to that of one of our 12-inch ultraportable Acer TravelMate 3010 (see video). 1 cm between the total width of the keyboard. It's just in absolute terms, but it makes using even more difficult.

To communicate with the outside, the manufacturer has with the following connectors: VGA, USB x3, 2 memory card readers, 2 mini-jack and a WiFi module 802.11b / g The SD card reader can be used to increase the capacity of storage. The capacity of an SD card and is in addition to 8 GB of memory.

Office, multimedia. This part must begin with the operating system of the machine. It is a distribution Linpus Linux. His Very simple presentation. 4 worlds, each represented by a color, a series of large icons and a type of use are available (see photo of box):

Connectivity: Internet, messenger, mail, Work: Open Office suite, text editor, spreadsheet, contacts, etc.. Fun: video playback software, music, games, webcam, photo editor. Files: Documents, video, music, file manager

Three icons, corresponding to three programs are available in the general interface. You can, however, access to each world by clicking on an arrow to find other programs.

If the application launch is very fast (it only takes a few seconds to launch a movie or capture software), use multitasking is not recommended. Video playback, for example, uses much the processor and move the mouse causes significant slowdowns. The transfer rate from the SD card reader, is not for rent. With a ceiling of 9.79 MB / s for large files, it is less than half the tenors in the field. This is also true for USB transfers and copying files very slow overall.

The Aspire One is not a stupid race. That said, this is not what we want. On the basic tasks required, surf the Internet, watch movies, send an e-mail, it is very powerful. We just have to be content. To complete the communication part, Acer has equipped this product a 0.3 megapixel webcam. Far from being the most just dive and color quality (I'm not naturally as red), it is still a handy accessory. The sound captured by the microphones is a little muffled. We finish, as usual, this part with autonomy. The battery of the Aspire One such as Acer BTP-43D1 Battery, Acer TravelMate 220 Battery, Acer BTP-58A1 Battery, acer BTP-60A1 Battery, Acer TravelMate 240 Battery, Acer BTP-52EW Battery, Acer BTP-63D1 Battery, Acer BTP-42C1 Battery, acer BTP-44A3 Battery, Acer BTP-550P Battery, Acer BTP-73E1 Battery, Acer BATCL50L Battery, Acer TravelMate 290 Battery took 1:58 minutes movie playback. This result can be improved with the use of a 6-cell battery (3 in this version) sold separately by Acer. Play. The game play is obviously not the strong point of this netbook. These applications are basic but entertaining.
