Would like to know why the battery from your BlackBerry in standby make such a different charge may use a simple how long depends on many factors – your specification model 3G mobile phone are not if they want to use Wi-Fi or Bluetooth, as well as ‘with the use of regional coverage intensity has a certain relationship.

So how do you ensure that your BlackBerry battery as efficiently as possible to use it?

Maximizing the use of battery life BlackBerry is the real key to the functions and features when what the reason because of your power drained and then you can reduce unnecessary wear.

The predecessor of this article that I published in about two years ago, an article on the BlackBerry user to improve the battery life of the article offers five tips to read before check-in and then take a hit a look at that original, they are my old works continue distillation. Latitude D500 battery Latitude D505 battery

Digested earlier in the tips that you can, after the appropriate next step to realize that these proposals are the most advanced

1) Be prepared for

Young Pioneers to “always ready” Oh!

This view is generally used to optimize the battery reserve time, because once you’ve prepared the next time one of the questions you can carry with it the damned Blackberry stroll around the farm.

The first is prepared: BlackBerry Travel Charger I’d rather not take American Express cards to be prepared by a BlackBerry Car Charger In fact, I still work at home on stage is resurrected in a computer bag has Swing bed so I phone every day, “Chen Bo,” the.

Next: extra battery for my BlackBerry 9700 with me anyway, the upper part of the existing four-Bold 9000 mobile phones are compatible with the specifications in the same place two full power to the laptop bag in one place the car remains a rest in my writing desk drawer of this article to take both to a mobile phone manufacturers Seidio accessories produced by a unit external load on the list. PA3399U-2BRS PA3465U-1BRS

I on the table there is a pod load BlackBerry is really convenient that suddenly become my favorite you only need a USB external jack for books, and when the need to recharge a mobile phone set up enough.

Therefore, these down to one thing: I’m only in each place where the battery ran out of May all the preparations for an extra battery and charging devices, you do not really need Oh, BlackBerry Battery, especially when you use your old equipment is also the case when the charger when you need because when the batteries are also only need about 20 US-knife Just go to the website of Amazon, I often (AMZN) Amoy I need.

Charge the phone at any time is a good habit that is, you have half or more of power, I prefer to use the above basis Pod charger to recharge because the load when used to enjoy on the screen that displays a digital clock that splendidly also gives me the charge was the most diligent Hey. A1045 PowerBook G4 15 battery

2) Avoid too many matches and the media to cover the electricity consumption

The machine machine young BlackBerry has enough cattle Breaking multimedia feature allows you to download / store / listen / watch all kinds of media content, you can play music in the memory card can also be used streaming video watch NBA games listen to the radio network in your beloved, you can also download your hands on the BlackBerry program in the world circuit and so on.

However, each of these applications will drain your battery while the poor, to save power to minimize your Zexu this does not mean that we can not fly to Las Vegas, a trip to play 21 -point game or listen to Internet Radio Slacker Poker Radio Music Radio.

But it should be noted that a request like that, especially in wireless connectivity and continuous data flow of brush cells are particularly vulnerable to suffer encroachment as a casino in the machine like a lot of hunger and thirst, drop ** This software requires you to use when he stays on the screen Oh, also benefit from each power backlight. FRU 92P1141 40Y6799

If the battery does not spare, or did not intend to charge close to using the data connection, then must be aware of the rational allocation of batteries.

3) Understand and use your data connection, wireless

In the previous article, I taught this way will not go into details here, but I would add two points can also be bar.

You can easily open and close the BlackBerry wireless connectivity, simply click on “Manage Connections”, you can easily adjust mobile / Wi-Fi / Bluetooth connectivity.

Although homelessness can be disabled when the data connection to open “Manage Connections” Select “Service Status” key to highlight the use of BlackBerry mobile network option to be able to disconnect the data service.

Ask “Close the data connection may be extended for help, but it will result in the most basic applications of one of the programs require Internet access is not valid and the functions of information such as telephone services Data still need to be able to work (I found that when the holidays when would continue to call they will not see a message such assistance to me) Inspiron 5150 battery Inspiron 700m battery

If you want to open the data service just use the other hand according to the above operation can be.

If you use the 3G GSM models like the BlackBerry Bold may also be closed by the fast 3G and 2.5G connection to choose slower or EDGE connections, or arguments in the management option of mobile network operator to roll down to highlight the attention network model for your Back to the 3G model of the former can not access the 3G network is the same.

4) Close unused programs – that is, you are immediately re-opened

As the place where I was before the sermon came here a little deeper, to discuss the matter further.

A number of procedures applied to RIM’s BlackBerry push technology that notification and reminder services such as information received almost simultaneously after the update to your device to facilitate such a data set of practice devoted to Daoshi the real exchange updates every time data connections Applying the shorter life of the battery. RN873 Y6142

So my suggestion above is only relative to neutralize these energies “high” program today, I urge you, do not close together will not receive updates on the contents of a reminder in the need to see a specific program to open the

This also applies to the instant messaging software such as BlackBerry users preferred BeeJive or IM +, and once you do not like me, interested in the words of IM programs when necessary to open a bar.

A quick way to see running in the background is to use your BlackBerry switch curriculum, similar to those basic processes BlackBerry Messenger message ah ah what the browser is closed, but can not pass the the other, you can disable the reasons Programs menu.

5) Sleep mode is a good friend

Idle when you can simply leave BB in standby mode, it blocks not only the keyboard but the screen and keypad backlighting to achieve energy efficiency. hp Pavilion dv2000 battery  hp Pavilion dv6000 battery

The means to activate this feature many new models at the top or side a long press the MUTE button has become.

For example, whenever my pocket 97 according to the law of the former director of the mute button at the top to open the silent mode (it is not the last Baidu Google it) some specific models is not to say that I know Storm2

Stop and start the standby mode, it needs to click the mute button or other combinations of keys to find your cell phone while driving, but the key reaction to determine if the Mosha day.

6) Turn off the camera flash lights

Suppose you often want to use the BlackBerry section of the camera, but the lives of more battery or turn off the flashing lights first, shoot once or twice depending on how the energy consumption does should not frequently used is the opposite. PA3383U-1BRS PA3395U-1BRS

Change the camera settings to use keyboard shortcuts and icons on the frequency point of the click open the viewfinder of the BlackBerry menu button highlight select lights flashing default set to “OFF” on the list may also be directly by a closed space

Press back the next time you open the Options menu to save the settings when the lights flash does not light, however, still is.

7) Due to add e-mail accounts

Each time an e-mail, or a group of information sent to the BlackBerry device to your inbox on the total consumption to save A1008 A1012 battery life, so you need to add that “relevant” e -mail accounts on the phone.

Suppose your BlackBerry analogy, it is Microsoft (MSFT) Outlook and Gmail account, a Windows Live Mail (MSN), Yahoo Mail and you want to assign a common account that the cost of electricity is large.

Outlook Bar may be particularly relevant to the work of your BlackBerry is the time, but you really need to make the old Gmail is also the Yao MSN mail?

The most frequently used e-mail device to bind is a good habit to reduce the tax e-mail is also a standby time of the upgrade is also optimized for the information pack mobile, why not Oh. F2024B F4486B

1. Battery Category

Lithium-ion VGP-BPS10 battery and a cell phone to the situation, generally divided into an external battery and built-in battery, to name a very easy to understand, external battery that is directly installed in the backs of hands, for example: 191 MOTOROLA, SAMSUNG series, etc.; High battery is charging cell phones, but another shell, one in the loop when cell phone batteries, such as: 998.8088 MOTOROLA, NOKIA most models

1. External Battery

External battery pack in the form of ultrasonic welding and loop two kinds:

1.1 Ultrasonic Welding

Shell

Such packages are below the battery casing points, ABS + PC hardware is generally expected, the shell surface treatment injection, in general, the model names: 191 MOTOROLA, SAMSUNG series, the original battery cover long-term use after treatment with injection does not normally wear flowers, and some brands to spend a few days the Dell Inspiron 1300 battery cell or parallel shells began to fall off the fuel injection. The reasons are: the shell of batteries for mobile phones are cheaper, the cost of treatment is usually injected shell several times (good), so that the processing involves three steps: Spray Varnish (land), injection (the formation of color), then light oil spray (the order should be, if I remember correctly), while some manufacturers to reduce the cost of disposing of the proceedings at first and third work order the cost is very low.

The ultrasonic welding presses

His role as follows:

The best of the industry should be made presses ultrasonic welding of the letter Electric Co., Ltd., Shenzhen, Kuwait product.

Welding

With good presses ultrasonic welding does not OK if the weld with the equipment and presses Shell welding setup has a lot to the outer shell is made primarily with manufacturers of relevant equipment to nozzle doping situation, while parameter configuration must find their own way for the company because it involves a number of F4486B technical, unable to say more.

1.2 cards Button

The principle of snap-in design of stacks of the lower crust to form the snap-in, which is usually only once, if the card is getting better off the user opened strong, then it can not recover, but it is not important for the manufacturer in terms of difficulty (good map then folded open), and its representative models: Ericsson 788, Motorola V66.

2. Built-in battery

Built-in battery, there are two forms of sealing, ultrasonic welding and packages marked (using the brand will be the battery all packed)

Ultrasonic welding of the battery are mainly: NOKIA 8210,8250,8310,7210 and so on.

The subject of the VGP-BPS9 battery a lot, like the previous two years was MOTO998 Hu, 8088 by.

2. Lithium-ion battery circuit protection (PCM)

Section II of lithium-ion batteries by the knowledge that we can see that the lithium-ion batteries need at least triple the protection —– Over-load protection, over-discharge protection, protection short-circuit, then they should generated a circuit protection, the protection requirements of circuit protection for these three objectives:

Protection against overload: Protection against overload principle IC as follows: When an external charger for lithium battery, when, to avoid a temperature rise caused by increased internal pressure must terminate the charge state. At this stage, the need to test the battery voltage to protect IC when the time comes to 4.25V (assuming that the point of overcharging 4.25V) or start on the protection of burden would cut the MOS power since the opening, closing and the load.

Over-discharge protection: over-protection principle of the landfill IC: To prevent over-lithium batteries discharge, lithium batteries connected to the case load, when the battery voltage is lower lithium the more-developed discharge voltage detection (assumed to be 2.5V) will start over-discharge protection, power MOSFET to cut the discharge passage of the open-ended to avoid battery-phenomenon discharge, and keep the battery low quiescent current in standby mode, currently only 0.1U. When the lithium battery is connected to the charger and the battery voltage lithium is greater than this period of excessive discharge voltage, over-discharge protection is lifted. In addition, taking into account the conditions of discharge pulse, excessive discharge detection circuit with time delay to prevent malfunction.

Over discharge protection and support to protect the IC main manufacturers are: Mitsumi (MITSUMI), Seiko, Taiwan Fu Jing (DW01, FS301, 302), Ricoh, Motorola, packaging, etc. mainly for SOT26, SOT6

Overcurrent and short-circuit current

For unknown reasons (discharge or negative by metallic objects inadvertently) caused by over-current circuit or short, to ensure security, you should immediately cease its discharge. Terms runway Principles of protection against overcurrent IC, when the discharge current is too large or too short occurs, the protection of integrated circuits should start (short circuit) the current protection, over current detection at this time is power MOSFET’s Rds (on) as a sensor monitoring the impedance voltage drop in the case, if the ratio set by the A1060 voltage-current detection is higher when the discharge stopped, the formula is:

V = I × Rds (on) × 2 (V-for over-current detection voltage, I the discharge current).

Suppose V = 0.2V, Rds () = 25mΩ, and protect the current size of I = 4A on.

Similarly, too much time current detection delay should also be provided to prevent current flow generated when there are unexpected failures.

Usually, after the election of overheating if they can remove the excess current factors (such as the charge immediately and out) will resume its normal state, may proceed with the normal load, the discharge action.

Devices for energy storage for dynamic current of the battery are: the lead-acid batteries, nickel-hydride batteries, metal and lithium-ion batteries.

Span of lead acid batteries contain toxic substances like lead, and high energy density is low, charge and discharge and short life, the refractory waste and other shortcomings, has been largely eliminated by future systems energy storage [1].

Ni-MH batteries are alkaline batteries, due to tension monomer is relatively low, and there is “memory effect” on a regular basis the large-scale dumping is necessary, which greatly increased the tasks of system power management . Secondly, its also self-discharge rate (10% ~ 15%) of defects [2-3].

In comparison with other batteries, lithium-ion IBM ThinkPad T40 battery with high power density (800W/Kg), single high-voltage (average voltage of 3.6 V), does not pollute the environment, self-rate discharge is low (about 3% ~ 5%), there is no “memory effect” and other characteristics, is an ideal battery power [4], it has been widely used in mobile power , hybrid cars, the switchgear and low voltage devices in standby power, such as space flight, the device energy storage.

An internal force of the lithium-circuit fault protection

Monomer average voltage of lithium battery is only 3.6 V, the discharge current also certain requirements. To improve the current system and level of tension, in some occasions, generally use parallel dynamic series after the formation of high-current, high voltage Li-ion battery as the energy systems. As the voltage is very sensitive to lithium batteries, batteries are generally increased when using a certain protection circuit. View the most dynamic of the internal circuitry of lithium battery protection was found, its protection circuit is fairly simple, usually only over / under voltage / over current / short circuit protection. In normal use, this hp F4486B battery can be normal in a short time of loading and unloading. However, the inclusion of the protection circuit with lithium batteries used in systems for hybrid electric vehicles are going through a phase of high current discharge and charge, we found the maximum voltage between monomers and lower voltages serious inconsistency: Yes monomer other batteries in charging the battery voltage is always under normal conditions, because its threshold voltage has reached the maximum protection of recharge channels are closed, resulting in the total pressure on the entire energy system can not pre-determined requirements, another set of monomer battery voltage is still within the normal discharge conditions, because of its voltage reaches the lower threshold voltage is closed to protect discharge channel, causing the entire energy system can not be fully discharged. These two phenomena have seriously affected the performance of energy systems for monitoring the equalization of the toshiba PA3383U-1BRS battery is to solve the above-mentioned phenomenon of the most effective approach.

2 Improved Lithium Battery Protection Circuit Principle

A balanced circuit is the first man to reach the hardware circuit, which may limit the battery voltage of the monomer or monomer between the coherence between the minimum voltage to effectively protect the battery charge voltage and lower the ceiling voltage discharge , from a fundamental to reduce the impact of the battery on the system to improve battery performance and extended to battery life. It includes the balance and balance of both types of circuit to its name suggests, they were the maximum protection of the battery voltage and the voltage limit of the battery.

In this paper, two sets of vehicle design hybrid electric power system: Series 3 Li-ion battery system protection (maximum voltage of 12.75V, the average discharge voltage of 10.8 V) and channel 10 system lithium apple M8403 battery protection (maximum voltage of 42.5V, the average discharge voltage 36V), discharge current, 10A and 40A respectively. System principle illustrated in Figure 1, which is in its protective circuit basis (over / under voltage / temperature / over current / short circuit protection) based joins the upper and lower balance circuit.

2.1 EQ TL431

TL431 is a three-terminal shunt tube regulator, its basic features can be found in reference [5] This article, based on the characteristics of their designs on the balance of the circuit shown in Figure 2. Adjust R1, R2, R3 resistance when the voltage exceeds a set value when they opened TL431, through the resistor R * Power consumption of energy to reduce battery voltage to reach a fixed point (equilibrium point). With the internal electric vehicles and electric vehicles equipped with a balanced circuit experimental results when the balance to be 4.20V, the resistance values are: R1 = 68kΩ, R2 = 100kΩ, R3 = 4.3kΩ.

The balance of the next circuit based on TL431 as shown in Figure 3. When the switch is off, because of optocoupler 817 is not opened before the class to optocoupler circuit also unable to work after school, the work of the BATCL50L battery in a state of normal discharge; When closed, the Post optocoupler optocoupler stage with the opening of the first class one after another opened, the circuit through the resistor R18 to reduce energy consumption and protect the chips sent until the voltage battery is low to protect the chip to force the battery voltage is stable at its low voltage limit Vmin, to achieve the objective and balanced.

From this principle of a balanced circuit can be seen that the current balance of the circuit can not exceed the upper limit of protection TL431 current (70mA or so). Capacity constraints due to a balanced, high-current charge and discharge can be applied between the circuit. To increase the balance of the circuit without compromising the ability of TL431, the TL431 can be used in parallel.

2.2 Parallel equalizer TL431

TL431 shunt and balanced the circuit shown in Figure 4. The principle is similar to Figure 3, only through parallel TL431 for the balanced expansion of current targets. Found in the actual production, as TL431 has a small difference between doing two average balance of power is not entirely consistent. To reduce the occurrence of these phenomena, the general screening methods to improve the TL431 for these circuits, which probably increased the workload of production.

2.3 Improving the equalizer TL431

To improve the balance of the capacity of the circuit, while reducing the workload of the TL431 output filter, this article using the 8550 design of an improved balance of the circuit of power transistor as shown in Figure 5. Once the extra power when TL431 will open, 8550 launch of a PN junction due to handle pressure and opening resistors consumes IBM ThinkPad T41 battery power until the battery voltage on the equilibrium point. Once balanced, the figure would be light-emitting light-emitting diode has played the role of operational instructions. By adjusting the set R1, R2, R3 resistance, they can set the balance point of the upper spring. Figure R1, R2, R3 resistance is relatively large, after the close of the TL431 little effect on the equilibrium point can be ignored. And the balanced circuit is also shown in Figure 5, only a change of R1, R2, R3 corresponding resistance.

3 Experimental results

The compositions of these functions with a string of 10 Office of Protection of lithium batteries a 400W DC motor driven experiments and found that all protective plates in a lithium battery when the total pressure of about 42.5V charging off tube protection against surges on the ground, pressure or almost total 29.2V for the discharge out of the market when the protection of the tube voltage, protecting the plate with a battery pack lithium in the testing stage for overcurrent detected: discharge current of 39A or more, the protective panels were made over-current protection, temperature of 109 ° C when the switch in the off-discharge circuit, the effective protection of the market of the discharge tube. The above data indicate that the circuit is essentially achieved the over / under voltage / over current / over-temperature protection, the basic requirements.

After a long round-trip charge-discharge test, collect relevant data, drawings, can be achieved without a balanced circuit waveforms comparing the experimental data are: the balance of the circuit of a hp PP2182D battery lithium and lithium 2 upper limit of the variation in battery voltage, such as that shown in Figure 6 and Figure 7, the ultimate balance of protection of lithium batteries 3 times the upper limit of battery voltage changes as shown in Figure 8, and balanced with the protection of batteries and lithium batteries 4 of 5 threshold voltage to change the battery of Figure 9 and Figure 10 shows the non-balanced circuit with 6 cells Lithium minimum voltage of the battery as shown in Figure 11. Figure 1, the points of all curves measured for the first time the limit of the battery (bottom) voltage, curve 2 points for long term running of the toshiba PA3395U-1BRS battery measured upper limit (lower) the voltage value.

On the accession of a balanced circuit the maximum voltage of the battery is maintained at an equilibrium point of 4.22V and 4.18V or more, effective protection of the upper limit of the battery voltage, non circuit to balance the maximum voltage of the battery which seems random, by virtue of membership of a balanced circuit the battery voltage level is maintained below the equilibrium point around 2.91V, the effective protection of the lower end of the battery voltage, non-balanced circuit limits the voltage of the battery which seems chaotic, badly damaging the battery life of the nature of coherence and the.

This departure from the practice of engineering, the dynamic nature of lithium batteries in a phase of high flow discharge occurred after the upper and lower limits of the phenomenon of unequal tension is proposed based on the balance of the circuit TL431, and lithium-depth study of a balanced circuit. Practical results show that the design and balanced on the balance circuit and the circuit not only ensures high speed of discharge of the battery after the battery requirements of consistency, but also effectively protect the battery voltage the upper and lower limits for the further study of high battery performance energy storage systems and hybrid systems for electric vehicles has laid a solid foundation.
