Prolonging life in multiple cells through cell balancing

19 Apr

Analog front ends that balance cells and eliminate mismatches of cells in series or parallel combination significantly improve battery (Sony vgn-fz battery ) efficiency and increase the overall pack capacity. As the number of cells and load currents increase, the potential for mismatch also increases. There are two kinds of mismatch in the pack: State-of-Charge (SOC) and capacity/energy (C/E) mismatch. Though the SOC mismatch is more common, each problem limits the pack capacity (mAh) to the capacity of the weakest cell.

Cell balancing principle

Battery pack cells are balanced when all the cells in the battery (Sony VGP-BPS9 battery ) pack meet two conditions:

  1. If all cells have the same capacity, then they are balanced when they have the same State of Charge (SOC.) In this case, the Open Circuit Voltage (OCV) is a good measure of the SOC. If, in an out of balance pack, all cells can be differentially charged to full capacity (balanced), then they will subsequently cycle normally without any additional adjustments. This is mostly a one shot fix.
  2. If the cells have different capacities, they are also considered balanced when the SOC is the same. But, since SOC is a relative measure, the absolute amount of capacity for each cell is different. To keep the cells with different capacities at the same SOC, cell balancing must provide differential amounts of current to cells in the series string during both charge and discharge on every cycle ( Sony VGP-BPS8 battery ).
Cell balancing electronics

Cell balancing is defined as the application of differential currents to individual cells (or combinations of cells) in a series string. Normally, of course, cells in a series string receive identical currents. A battery pack requires additional components and circuitry to achieve cell balancing. However, the use of a fully integrated analog front end for cell balancing reduces the required external components to just balancing resistors (Sony VGP-BPS5 battery ).

It is important to recognize that the cell mismatch results more from limitations in process control and inspection than from variations inherent in the Lithium Ion chemistry. The use of a fully integrated analog front end for cell balancing can improve the performance of series connected Li-ion Cells by addressing both SOC and C/E issues.[68] SOC mismatch can be remedied by balancing the cell during an initial conditioning period and subsequently only during the charge phase. C/E mismatch remedies are more difficult to implement and harder to measure and require balancing during both charge and discharge periods (SONY Vaio VGN-FZ battery).

This type of solution eliminates the quantity of external components, as for discrete capacitors, diodes and most other resistors to achieve balance.

Hazards

Explosion

A battery explosion is caused by the misuse or malfunction of a battery (Dell Inspiron 6400 battery), such as attempting to recharge a primary (non-rechargeable) battery,[69] or short circuiting a battery.[70] With car batteries, explosions are most likely to occur when a short circuit generates very large currents. In addition, car batteries liberate hydrogen when they are overcharged (because of electrolysis of the water in the electrolyte). Normally the amount of overcharging is very small, as is the amount of explosive gas developed, and the gas dissipates quickly. However, when “jumping” a car battery, the high current can cause the rapid release of large volumes of hydrogen, which can be ignited by a nearby spark (for example, when removing the jumper cables).

When a battery is recharged at an excessive rate, an explosive gas mixture of hydrogen and oxygen may be produced faster than it can escape from within the walls of the battery ( Inspiron 6400 battery), leading to pressure build-up and the possibility of the battery case bursting. In extreme cases, the battery acid may spray violently from the casing of the battery and cause injury. Overcharging—that is, attempting to charge a battery beyond its electrical capacity—can also lead to a battery explosion, leakage, or irreversible damage to the battery. It may also cause damage to the charger or device in which the overcharged battery is later used. Additionally, disposing of a battery in fire may cause an explosion as steam builds up within the sealed case of the battery

Windows 7 is investigating the accidental injury for laptop battery

18 Mar

Many notebook users upgrade to Windows 7 from Windows XP / Vista discovered, the new system severely shorten the Dell Latitude D830 battery life.

Official Microsoft TechNet forums, there are users post and said he put himself in 2007 bought an HP laptop to upgrade from Windows Vista to Windows 7, but the  Laptop battery life but never became a mere two hours, half an hour, but Microsoft is repeatedly promote the new system which can significantly extend the Inspiron 1520 battery  life time. Other parts of the web forum had a similar question.

It is reported that Windows 7 is the root of the problem and adds a new battery testing tool that can determine whether the battery needs to be replaced and inform the user, but in some cases, even though the Dell Inspiron 1520 battery business is as usual, the system will judge whether the error that the battery has been exhausted, and recommended that users immediately replaced, and sometimes even directly shut down the system. Some users reflect the frustration that he did you are prompted to replace the old battery, but the new battery or continue to receive the same warning.

Some people say that this issue as early as Windows 7 Beta testing phase existed, but some say that the official version of RTM where phenomena which was Posted by a user and he said: “In the RTM version of Windows 7 prior to installing the Dell Inspiron 1520 battery , I have been normal, in my installation of all the Beta and RC versions where can persist for nearly three hours. Now, only had about 20 Windows 7 minutes to put my notebook shut. This situation is in my shift from the RC occur when the RTM. Needless to say, I have a very bad mood like everyone else. ”

Microsoft said in a statement that the problem has been known and noted, and Windows 7 read the way the system firmware in many different types of notebook manufacturers are present. Microsoft said: “We are working with hardware partners to investigate this issue. Windows 7 with firmware information to determine whether the Inspiron 1526 battery
 needs to be replaced. We are working with partners to find root of the problem, to obtain the necessary information and guidance and then go in (TechNet) Forum Update. ”

Microsoft also claimed that sometimes the new tool is working correctly, in other words, if it prompts you to replace the HP Pavilion DV8000 battery , it is possible your battery really has to be hung, but the chances of false positives is clearly too high.

Dell Laptop battery maintenance guide

07 Jan

Laptop Battery is the consumables, with a limited life expectancy, most manufacturers warranty for the notebook battery time ranging from three months to a year, Dell is to follow industry standards to provide a limited warranty for one year. For batteries, use the correct and proper storage, can significantly extend the Dell Inspiron E1505 battery life of notebook computers.

First, the battery useing must follow some attention points.

1. When you use laptop with external power, you dont need to take out the battery.

a. There is a chip to prevent over-charging in the mainboard. When the rechargeable battery power to 100% state of charge, the charge control chips (FET) will stop charging the battery. We do not have to worry about damage to the battery.

b. Connect the dell inspiron 6400 battery to avoid loss of BIOS information.

c. To prevent a sudden loss of power break.

2. To prevent exposure to prevent damp to prevent the erosion of liquid chemicals, batteries to avoid contact with metal objects, such as exposure to short-circuit occurrence.

3. Long-term do not use notebooks, how to store the dell inspiron e1505 laptop battery?

We will have a period of time not to use the notebook, the insprion e1505 battery is fully charged to preserve, or to be released after save electricity?

Put long-term preservation of photoelectric batteries will lose their activity and even lead to the control circuit protection self-locking and can not re-use, full of power will bring about long-term preservation of the safety problems, the best method is to save electricity use to 40 or so and then stored in cool dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to come up with to use a inspiron 6400 battery, the battery can ensure a good state of preservation, but also does not allow the loss of electricity damage to the battery completely.

How can I exam the Dell battery power?

Remove the battery, press the Macbook Pro battery power signs, we can see the situation of the five battery status lights. For two bright, representing 40% of the electricity. Electricity on behalf of the entire light is sufficient, if the 135-light, that damage the battery.

Second, how to extend as much as possible the work of laptop battery time?

1. To reduce the screen brightness. How to adjust the brightness of the use of inspiron e1505 laptop batteries, boot by F2, into the BIOS to adjust the Brightness of Video. Or fn + down / up key combination to adjust the brightness quickly.

2. Open the CPU speedstep feature, you can greatly extend the working hours of latitude x300 battery; Cpu’s speedstep feature is enabled by default BIOS of. When using batteries, cpu will automatically down-use, in order to achieve energy-saving purpose. If not enabled, please start by F2, into the BIOS found in Performance, for the Speedstep Enable setting Enabled. (An earlier version of BIOS is the Alt + P to the sixth page, modify intel speedstep)

3. make the best use of standby, sleep and other functions. When a longer period of time without a computer, allowing notebook standby or hibernation, both to save power and extend the life of the computer. (Tips: Please confirm the successful installation of graphics drivers, power management options can be set up.)

WINDOWS in the process of power management settings, we generally can be set to “portable / laptop” (Portable / Laptop).

At the same time suggest that you will use the dell inspiron 6400 battery when the wait time to close the monitor is set to 5 minutes, so when we do not operate within a certain period of time the notebook, it will direct the state of black screen, so other than the screen saver to run more power.

4. when using the battery as much as possible the closure of wireless, Bluetooth and infrared ports. At the same time to remove without the use of peripherals and to avoid the opening of a large 3D program, games and so on, in order to reduce unnecessary battery consumption.

Of course, on the controversy over the use of batteries, there are divergent views have any objection if we can http://bbs.dell.com.cn forum to ask questions, let us discuss how to maintain the battery.

Li-ion battery or change the pattern of auto parts

04 Jan

Nihon Keizai Shimbun said Japan’s largest industrial electronics group Hitachi plans to expand its hybrid vehicle lithium-ion laptop battery production capacity is expected to invest 200-300 billion yen, with the aim by 2015 to expand production capacity 70 times. Hitachi will be this fall before the initial expansion of production capacity of more than 600 percent.

Currently, General Motors, Hitachi has already received 100,000 units for the production of hybrid vehicles under the orders of the lithium-ion dell inspiron 6400 batteries, General Motors plans to sell the car next year.

Reports that focus on access to domestic and foreign orders for motor vehicle dealers, Hitachi will expand production capacity to meet the needs of 700,000 vehicles each year the demand for hybrid vehicles.

If the electric vehicle automotive oil after use of the mainstream, then the electric vehicle with lithium-ion batteries will certainly be popular, and in-depth aspects of lithium batteries R & D and investment in the future of the enterprise will become the giant auto parts industry, and may even change the world the pattern of auto parts suppliers. In recent years, the production of automotive lithium dell inspiron 6400 battery, dell inspiron e1505 battery are not businesses in the global list of hundred auto parts, auto parts enterprises existing hundred only Bosch, the mainland group, Magna, Johnson Controls, Hitachi (automotive business ), such as lithium batteries also attempt to occupy the leading position in the field, and most of the way through joint ventures or acquisitions to achieve the unfamiliar, but the huge market potential for control.

Li-ion battery production plans of enterprises are taking a joint R & D and production methods, which will not only reduce the risk of individual enterprises and cost, there will be some non-vehicle lithium-ion battery business (such as Toshiba, Samsung SDI, LG Chemical ) to enter the field of auto parts matching, and these new market entrants of the parts could have been better hundred enterprises.

Car companies, only Toyota, Honda, Nissan, DaimlerChrysler, BYD, such as direct investment (in the form of joint ventures or own) the production of lithium batteries. Ready to be launched in many hybrid or electric cars, but the core does not have its own battery supplier, the lithium inspiron 6400 battery, inspiron e1505 battery in the car in front of the bargaining power of enterprises may be an improvement than it is now.

However, these lithium-ion battery business is also facing significant cost pressures and the threat of trade protection. Such as Japan, South Korea on the implementation of production and marketing of lithium-ion battery authentication system in which the Japanese concern for trade protection. We can see that the lithium batteries is safety on the auto parts industry event, the major automotive markets abroad are careful to protect their own R & D and production capacity.

For lack of independence, the core technology of automotive components in China, the hybrid / electric vehicle battery and electrical system, it is China-related enterprises have become the world’s leading providers of an important opportunity. In this regard, the Chinese enterprises and overseas there is no gap between the core technology components are now so large, nor abroad many years earlier than China. Coupled with the cost advantage of China itself, as well as in electric bicycle battery (especially lithium batteries) has ac***ulated experience in China is entirely possible in the hybrid / electric vehicles using lithium battery dell inspiron 6400, battery dell inspiron e1505 to produce high value products and the possibility of occupying the most high-end technology.

Dell inspiron 6400 – Three Unknown Base System Devices

17 Dec

I am not a fan of Windows Vista, which is the reason I still use XP. I am used to XP, have learned to make it work the way I want it, so I’m not in a hurry to upgrade.

About a year ago, someone I know purchased an Dell Inspiron 6400 laptop from Dell and tried to get XP installed on it instead of Vista. They had no luck and ended up with Vista. Recently, they have decided to remove Vista and install XP on that same laptop, and asked me to do it. No problem, Dell Inspiron 6400 Battery, at least until I ended up with three devices that weren’t recognized by XP.

If you have an Inspiron 6400 and have noticed three Base System Devices in the device manager,Dell Inspiron 6400 Battery, then I will explain how to correct that issue in this post.

Hardware and Windows XP

As I mentioned above, I recently was tasked with installing Windows XP on a Dell Inspiron 6400 that once had Vista installed. The one problem I encountered was that all the hardware installed was new, so XP didn’t have any drivers included.

I went onto the Dell support Web site and downloaded the drivers to the local hard drive. I installed the chipset, video, sound, network adapter and wireless drivers without any issues. After I rebooted I noticed that I still had three unknown devices in the device manager.

Unknown devices in the device manager means that I still need to install some drivers. Unfortunately, the devices were listed as a Base System Device, so it wasn’t very descriptive to help determine what I was missing.

After a quick search on the Internet, I read that there was an additional set of drivers for the card reader that was included in the laptop.

Dell Inspiron 6400′s standard 6-cell battery is absolutely not enough for a lot of people both in the work and in the life. For this sense, any possibility to enlarge the capacity of the laptop battery?

I strongly suggest that order an extended 9cell Dell Inspiron 6400 battery to enlarge the working time in,

I went to the Dell support site once again and expanded the Chipset drivers. One of the items in the list was called Ricoh – Driver, which I promptly downloaded and installed. After installing the drivers I checked the device manager and noticed that the three unknown devices were now gone. I also had three new card reader devices installed, which were the three unknown devices.

As a side note the Dell Inspiron 6400 battery is also known as the Dell Inspiron E1505 battery.

Summary

After installing XP on a Dell Battery Inspiron 6400 I noticed that there were three unknown Base System Device entries in the device manager. After some quick research I learned that these devices were the Ricoh card readers. I downloaded the driver from the Dell support Web site and the three unknown devices disappeared and were replaced by the actual devices.

A 9-volt battery is actually made up of six 1.5-volt cells. Those cells are actually quadruple size,Dell Inspiron 6400 Battery, but you can make them work in AAA compartments.

Watch this video to see how. With some needle-nosed pliers, pry apart the casing of the 9-volt battery. As long as you’re careful not to puncture the cells themselves, there’s nothing harmful inside. Once you get it open, pull off any casing that’s holding the cells together and you should get a sort of sausage string of cells.

Clip those apart, but leave some of the connector metal on each end of each cell. When you put them into a AAA compartment,Dell Inspiron 6400 Battery,bend the metal over to give you the extra room and conductivity to make them fit.

You may or may not be saving money here, since the cost of a 9-volt battery does run roughly 6 times as much as a single AAA. But in a pinch, the 9-volt battery could come in handy, just don’t expect to use it as a 9-cell inspiron 6400 battery any more after you do this.

Also via Kipkay, The Energizer brand of A3 12-volt batteries can be pried apart to reveal eight button-cell batteries, useful for watches and other devices. Here you’re saving money: the 12-volt is a couple bucks and each of the button cells can run about $5.

That’s it for now. Be careful if you do this, by the way. Don’t want you slicing up your hands or the dell inspiron 6400 batteries. Use proper protective measures.

Dell Inspiron 6400 laptop andy Battery Review

14 Dec

The Dell Inspiron 6400 laptop is a laptop that meets you. It’s pretty light and portable (like the Inspiron e1405) and offers high performance and great media options. Basically, you get the best of both worlds, at a reasonable price. Before we begin reviewing anything, here are the specs of my system:

Intel Core Duo T2400 / 5 Mb Cache / 1.83 GHz / 667 MHZ FSB

15.4″ Wide-screen XGA Display with Truelife

120 Gb 5400 rpm Sata Hard Drive

1 Gb DDR2 SDRAM / 553 MHZ

256 Mb ATI Mobility Radeon X1400 Hyper memory

Windows XP Media Center

9 – Cell dell inspiron 6400 Battery

Dell Inspiron 6400 Build & Design

The Inspiron 6400 feels very sturdy. It doesn’t feel flimsy, and doesn’t look like things are going to get loose anytime soon. Opening and closing of the screen is not too loose or too tight. One hand is sufficient enough to move the screen, provided the notebook itself on a stable surface.

The notebook design itself is slightly above average. The silver paint looks very appealing, but not when combined with the white bumpers. Overall this laptop can’t compare to the XPS series, but its design is good enough to catch some eyes.

Dell Inspiron 6400  Processor & General Performance

If you are a multi-tasker, you will love the Core Duo. For example, You were installing software, playing a video, and chatting on Windows Live Messenger at the same time with no troubles. Start-up time is very quick once you get rid of the annoying stuff Dell includes.

Dell Inspiron 6400 Noise & Heat

For the most part, the laptop is very quiet. When doing normal tasks such as word processing, email and Internet you don’t hear it at all. When doing more intensive tasks or prolonged use, the fan kicks in. This fan isn’t loud, but it isn’t quiet either. It’s not loud enough to bother you though. Heat is a small issue.

Wireless

The Intel Wireless card (Intel Pro Wireless) is very good using my standards. Dropped connections were limited and it was easy to use. You can easily shut it off when you are not using it by pressing Fn + F2. For this card, you can use the software Intel provides or the one Windows has, Windows Zero. I personally prefer Zero because it’s easier to use.

Dell Inspiron 6400 Battery Features:

New 7200mAh (9-cell) 11.1V Lithium-ion inspiron 6400 battery | High Capacity Extended life battery | Manufactured for Dell Inspiron 6400, E1505

Battery life on the 6400 is very respectable. Under normal tasks (WiFi on, 75% brightness, Windows Media Visualizations), the battery lasted about 3 hours and 15 minutes. With WiFi off, and playing games with low brightness, It was able to get about 3 hours and 34 minutes. This 9-Cell Smart Lithium-Ion Primary Dell Inspiron 6400 Battery has internal circuit board with chips that allow it to communicate with the notebook to monitor battery performance, output voltage and temperature. It also gives the notebook much more accurate ‘fuel gauge’ capability to determine how much battery runtime is left before the next recharge is required. This product has been tested and validated on Dell systems to ensure it will work with your computer and is compatible with Dell Inspiron notebooks.
