Common energy saving methods of laptop batteries

Filed under: Uncategorized

How to make good use of the batteries, how to extend his schedule and use of living and so on, is undoubtedly the troubled mind of the majority of laptop users on a problem, batteries laptops and skills to use the books before mentioned a variety of cellular networks, this requires us to use in times of peace to learn more and apply, so that saving becomes a habit, only to learn the practice will have concrete results.

1, in early hibernation

Temporarily using a laptop to save Dell 6Y270 battery power, you can set the agenda for power management, allowing the system to enter sleep mode after a period of time, but a shorter or longer will have to wait a few minutes, there is no way to make the system of the laptop immediately enter the sleep state?

Notebook computer system to allow quick access to the latent state of a simple method is to directly close the display. Press the representation would require little effort, you can make notebook computers to standby mode immediately and effectively save power. When you need to reuse the time, as long as the opening screen, the system automatically returns to pre-condition.

2, screen saver mode

TFT is the most important components of portable computer power to reduce its use of the IBM ThinkPad T43 battery when the power consumption, notebook makers have devised ingenious schemes, but generally are based on the screen brightness lower and even off the screen mode.   

In some settings management of laptop power you can customize the brightness of the screen, most laptops with a shortcut keys specific adjust the brightness of the screen, typically 6 to 8-setting brightness level.

Thirdly, the energy saving settings

Office machines using alternating current, most people may not be the computer attached great importance to energy saving features, but need to use BATBL50L6 batteries for laptops, using the Energy saving features should be taken seriously. How to design computer hardware more energy efficient, not a user problem to be solved. The user can be installed on the computer of the efficient use of energy saving option.  

Energy saving settings require the user to set two: First, the computer BIOS setup program on energy saving in the profile settings, the most important thing is that there Energy savings in many settings of the operating system and operations. In the practical implementation of computer systems, Windows systems should outweigh the energy savings settings in the CMOS settings.

1. BIOS power saving settings

In the CMOS settings, most had a "power savings", which may choose to "Maximum Battery Life" and "Maximum Performance" and other options. "Maximum Battery Life" is the recording power default setting mode. Computer power saving mode phones in several states such as Idle Idle, Standby (standby) mode Suspend mode suspend (sleep) mode. Laptops, these parameters were able to adjust energy consumption, mainly in computer power saving state, the timely closure of some without the use of system equipment. If the wait state, turn off the screen and hard drive, in hibernation, apart from a rigorous monitoring and the hard drive, but also the memory contents can be saved on the hard drive, basic maintenance system throughout the computer closed, once activated, or restart the computer, office will be refurbished and pre-hibernation state. The energy saving settings in the CMOS, mainly determined by mode waiting to enter standby Standby Timeout, set to enter Suspend mode from standby to suspend time Timeout. Travel BIOS Phoenix are the most common. Energy saving various BIOS settings may be somewhat different, it should carefully read the screen.

2. Windows in the energy saving settings

For the average user in the Windows system to operate a better understanding of energy management can be simpler. Windows Help file in the "management hardware and software" entries, there are two laptops equipped with energy-saving elements on "Manage Energy Use" and "use of mobile machinery "in the laptop power management." Energy saving settings in Windows, read the contents.

In the Windows "Control Panel", "power management click, you can open the" Power Management Properties "dialog box. In the" Power Management Properties "dialog should be" power management "is set to "Laptop" and reasonable settlement "system delay", "close the Monitors", "Turn off hard disks" and other options. Another computer can control the opportunity to have some differences, options for the new plant and the latest computer software will be easier to implement, the detailed parameters should be based on characteristics of the computer and Windows files Help to complete.  

In addition, if your laptop integrated infrared port, no time to ban it, it can be extended the life of the laptop battery.

4 alarm settings

Set alarm battery time to prompt the user to record information. Is to click on Open "Control Panel", double-click "Power" option, point "alarm" menu bar, alarm, battery low "column, Windows 98 default is 10%, "a serious shortage of battery alarm" column, Windows 98 default is 3%, which may make appropriate changes as needed. Click the [Alarm Response] button, the warning "voice" and "displays" are selected, the "power level" May of time to select. Alarm limits so that when the battery is used, it will display a warning dialog and the buzzer alarm sounds to alert the user to record information about the delay. Finally click [OK] to exit the settings of power management.

5, open the energy save function

Energy saving feature is the use of processor technology, which allows the performance of laptops are playing with their A1045 battery life between the time to achieve the best balance.

Most new notebook models in both the BIOS of the processor energy saving technology have given support, is enabled by default, if not open until the Enter the BIOS will support the option to open OK.

Battery Protection Board

Filed under: Uncategorized

As its name suggests, the committee battery protection is mainly directed against rechargeable (typically applies to lithium) the protective role of the integrated circuit card.

Lithium battery (rechargeable type) so in need of protection is determined by its own characteristics. As the material of the lithium itself determines it can not be more responsible, over discharge, over current, short circuit and ultra-high temperature charge and discharge the elements lithium to bring the Federation with a sample letter to the Czech resistance than the shield and a current insurance arrangement.

Li-functioning ion battery protection normally to protect circuits and devices present, such as PTC, or TCO jointly undertaken and completed, protecting electronic circuit consists of about -40 ℃ to +85 ℃, time and accurate monitoring of voltage and charge the batteries back into the path of current, real-time loop current control off; TCO PTC or the environment at high temperature, bad place to avoid damaging the battery.

Protective panels typically include IC testing, MOS switches, JEPSUN Czech Republic that the letter of precision resistors and auxiliary NTC ID memory, PCB and so on. Who will control IC in all under normal circumstances, control the MOS switch turn-on, so that cells communicate with the external circuit, and when the battery voltage or loop current exceeds the set value, it immediately (tens of milliseconds) control the MOS switch turn-off to protect the safety of BTP-43D1 batteries.

NTC stands for negative temperature coefficient, meaning that a negative temperature coefficient, the ambient temperature increases, its resistance to reduce the use of electrical equipment or a timely response to the charging device, control , stop charging and discharging of internal disturbances.

Memory for identity, often as a single interface, memory, ID is the identification of the acronym is the sense of identification, storage battery type, production date and other information. It can play the traceability of products and restrictions apply.

PTC is the abbreviation of the positive temperature coefficient, which means a positive temperature coefficient. Professionals within the device positive temperature coefficient is usually referred to as PTC, where the products of the PTC battery can prevent the temperature of the  Dell RN873 battery battery discharge current level and the emergence of dangerous, depending on battery voltage, characteristics of current density and application environment, TPC have specialized needs.

PTC is a component of cell products where a very important component of the cell responsible for the security of an important mission of his own performance and the quality is also a battery performance and quality is important.

Skid plate on a single power protection, design protection would be relatively simple, very technical, that is, for example on the platform of the battery power protection for board design issues to note the voltage, battery power in use often require a great platform for tension Therefore, wherever possible, designed to protect the advice to protect the Commission does not affect the discharge voltage batteries so that the control IC, the requirements of precision resistors and other components will be very high, the general domestic IC can meet the requirements of most products, special imported products can be used, resistance to stabilization of sampling that you must use JEPSUN Czech resistance to the letter in response to high precision, low temperature coefficient, no requests from the flu. Protection of multiple batteries of plate design, there are technical requirements higher, according to different requirements, the design complexity of different products.

Main technical characteristics:

1 Protection against overload

2, over-discharge protection

3, over current, protection short-circuit

How to extend the life of lead acid battery in electric vehicles?

Filed under: Uncategorized

First, the short-lived reason of Electric drive-acid battery
Lead-acid battery charging and discharging processes of electrochemical reaction is the process of charging, lead sulfate to form lead oxide, discharges of lead oxide is reduced to lead sulfate. When the battery electrolytic solution of sulfuric acid concentration of lead in the static timeout is too high or too long, they will "take as a group, to form small crystals, these tiny crystals of lead sulfate and attract around like a snowball that the formation of large inert crystal, causing a decline in work area of the plate electrode, a phenomenon known as vulcanization, when the battery capacity will decrease gradually until it can not be used. The depth of discharge, discharge at high voltage, the battery will accelerate healing. Short charging, the battery will be due to changes in oxygen excess and the exhaust valve open, causing water loss, so that the electrolyte concentration increased, the phenomenon of vulcanization aggravated battery. After loading discharge may be appropriate, training a large number of lead sulfate does not load if more than half an hour to restore the lead sulfide is oxidized to form crystals. In the production line of hp 417066-001 battery charging, the user with a car driving to use this time to go through a lot of links, the time interval, even for several months during this period, no right to supplement the battery power, self-discharge produced by lead from the sulfuric acid accumulation of a large number of crystallization to the user just bought a new battery in May have become obsolete or even the paper charges the battery.

Secondly, how to solve the sulfide battery
To reduce the hardening of the battery to extend battery life, we must first reduce body weight for a while when you do not use electric bikes to add fresh is best able to recharge after every shot and not the under voltage protection, prevent excessive discharge of the battery, you can also use specialized equipment for desulphurization and maintenance:

1. The use of office equipment desulphurization fast desktop desulphurization equipment works faster is a high voltage, high pulse load current through the elimination of a negative amount of sulphide block wear. This method is fast, fast, get a temporary suppression of the effect of the treatment, but the high voltage high current can blow desulfurization may also reflect the active substances, including the elimination of lead sulfide in the positive plate to severe dehydration and softening problems, fatal damage to the battery through the equipment in more than two sulfur base will be discarded after the battery. In addition, the current point for an addition to the professional maintenance of the basic fee of sulfur in 60 to 80 hours, up to six months, the life of the battery and is not the User substantial economic benefits. Currently, the battery on the market to maintain professional traders must understand the dangers of this approach.
2. Choosing to use a small house instrument repair maintenance

Repair and maintenance of instruments battery small appliances in parallel, this method is slower restoration, repair time is quite long, often more than 120 hours, but both charges discharge process is also capable of preventing and of eliminate the healing, repair works. Because low voltage and low current, do not have a major impact on the battery plates which leads to dehydration and mitigation, which is a user input can be validated at the track maintenance, especially for battery good news, its extended battery life of 1-3 times, and entry may be accompanied by an electric motor, the next time to replace the VGP-BPS2C battery, you can also continue to be used for users to save many economic costs. If a user once a year to replace the battery, a battery 350, the user must spend 10 years in 3500 to replace the battery on a conservative estimate, if the use of the instrument repair Home Maintenance twice the battery life of 10 years may also be registered in battery costs 1600 Yuan.

How to buy Ni-MH battery and charger

Filed under: Uncategorized

Ni-MH Battery:

Only recommend three brands: a giant two Sanyo Next Generation 3 (I think there are three options is enough, after all, the battery is not used to reflect the personality thing)

Sanyo Battery performance leader in the world, but the higher price (2100 to about 20 RMB / day), the performance of next generation, but a little good workmanship, the price is low (2100, about 15 RMB / day), super powerful general, work better, longer life expectancy may be more the next generation, but the high price (usually supermarkets are selling, we can examine their own)

Capacity: It is recommended to buy 1800ah (currently on the market for sale for most of 1800mAh rechargeable batteries) or 2100mAh battery and other small capacity of the CD is not good enough (DC is Electric tigre), then a wholesale volume may be much higher, was more profitable.

Magazine:

Points available in the market Charger fast charge and trickle charge, two chargers advantages and disadvantages, the main charging efficiency and battery life of contradictions, in general, slow-filling (referring to the burden of battery current is less than or equal to standard says that the capacity of 1 / 10 of the charger) on the cell damage is small, good battery life, fast charge effective, but the battery life is short, whereas the price is relatively high (the charger is generally proportional to the price and charging speed).

However, from my point of view of actual use, filling slowly another advantage is that the battery more complete, but with the fast charge while charging the threshold voltage is the same, but the actual use is always slower than using a small rechargeable battery 10 rechargeable shoot some photos.

What to buy this charger to use in DC depending on your situation, your number of backup battery, memory card the size of the habit of taking pictures or even your personality to decide.

Here we must remind everyone that, based on my experience, decided to shoot whenever I leave the length of time is not the battery, but my capacity memory card! — I use the A60, a set of batteries (4 Next-Gen 2100) can take over there is more than 128M card, and I do not have laptops, as opposed to my map so the battery used enough, but do not buy a quick charge should spend more to me —- 8 to 10 hours is fairly complete.

But if you’re impatient, or as the "fire" in camera mode, then purchase one or more distribution groups of fast charging the battery.

Also want to clarify is: load slow because of relatively safe, it can not be required in the choice of a very famous brand, but fast charging more dangerous, your personal property and safety considerations of the battery, It is recommended not to buy the brand!

Fast charge in the most famous is the series of Sanyo, and M53, 54.55 and A1045, very well, others, such as Super, the next generation can also be heard at the same time Penghui also very cost effective fast charge.

Today, chargers that can fill four 2100 batteries in100 minutes are numerous, such as Sanyo, quick charger possible, platinum the next generation four-wheel drive package, Penghui fast charge and so on, the Price 250-60 yuan, also important to note the following: rapid charger has a general time limit load (to protect), they are capable of full battery capacity is limited! but you can charge the second solution.

Some useful things about digital camera batteries

Filed under: Uncategorized

A digital camera battery is probably the most important digital camera accessory. Some digital cameras can consume power at an incredible rate, providing only a few hours of continuous shooting time before the battery is exhausted. Other cameras are famous for the long life of their digital camera battery which allows users to snap away with barely a thought to power consumption. It is important to know how you plan to use your camera and what kind of battery it needs. < ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />There are two types of Digital Camera Battery. The most widely available digital camera battery is a standard AA-size battery. The other type is a rechargeable battery that is made by the manufacturer, otherwise known as a proprietary battery. A proprietary digital camera battery offers the advantage of being lighter and more compact, but they are often more expensive, making the prospect of buying one or two backup sets much less appealing. The alkaline AA-size digital camera battery usually has a very short life - less than an hour in extreme cases - when used in a digital camera. This type of battery makes an acceptable emergency backup, especially if you are travelling with your camera. However, the Nickel Metal Hydride (NiMH) digital camera battery can be used instead of the alkaline ones with a Charger and this rechargeable NP-20, NP-40 digital camera battery has a substantially longer life at an affordable price. Another type of AA-size battery is the non-rechargeable Lithium batteries and rechargeable Nickel Cadmium (NiCD) batteries. The lithium digital camera battery has a superior life to alkaline AA’s and offers good cold-weather performance but their price and non-rechargeable feature make them less useful than rechargeable NiMH batteries. It is also important to ensure that your camera can take a lithium digital camera battery. On the other hand, the NiCD digital camera battery offers the advantage of retaining their charge while unused, unlike NiMH cells, but have shorter lives and need to be discharged completely before recharging which could be very inconvenient. The LCD screen of a digital camera is responsible for consuming the most power, so it is worth only using the LCD when necessary to help save the battery life. Always try to carry at least one backup set of batteries, especially if you plan on being away from power outlets for an extended period of time. The current alkaline AA-size battery can make a convenient emergency backup if your original digital camera battery fails.
