Scheme for the control of 3 lithium batteries. What is a battery charge controller

How big have Li-ion batteries entered our life. Those that stink zastosovuetsya mayzhe in all microprocessor electronics are already the norm. So, the radio amateurs have already taken them on their own for a long time and vikoristovuyut from their self-confident. I appreciate the significant pluses of Li-ion batteries, such as a small expansion, a large capacity, a great choice of vikonan of various capacities and forms.

The widest battery can be 18650 brand and the voltage becomes 3.7 V. For which I will work a discharge indicator.
Singingly, not varto rozpovidat, naskolki shkіdli for the battery in the tap is low їх discharge. Moreover, for batteries of various kinds. Proper operation of batteries to prolong your life for a lifetime and save your pennies.

Charging indicator circuit

The scheme to finish is universal and can be applied in the range of 3-15 volts. The reference threshold can be adjusted with a change resistor. So, it is possible to vicorate for either batteries, such as acid, nickel-cadmium (nicd) or lithium-ion (Li-ion).
The circuit checks the voltage and as soon as it falls lower for tasks, the light will light up, signaling a low battery discharge.
The scheme has victorious regulations (posilannya, de brava). Vzagali, tsey stabilitron є duzhe tsіkavim radioelement, which can make life easier for radioamators, with the help of schemes, tied to stabilization or threshold spratsovuvannі. So why take yoga for design, especially for the hour of life of life blocks, schemes for stabilizing streams, etc.
The transistor can be replaced by any other NPN structure, analogue KT315, KT3102.
R2-regulates the brightness of the light.
R1 - changeable resistor with a nominal value of 50 to 150 kOhm.
The rating of R3 can be increased up to 20-30 kΩ for energy saving, as a low voltage transistor with a high transfer coefficient.
If you don’t see the regulation of the TL431 stabilizer, then you can twist the radiant circuit on two transistors.

The reference threshold is set by resistors R2, R3. Instead of them, you can solder one change, in order to give the possibility of regulation and change the number of elements. Radian transistors can be replaced by BC237, BC238, BC317 (KT3102) and BC556, BC557 (KT3107).

The scheme can be selected on the board with overhead installation. Tighten the thermotube and blow it with a hot air gun. Glue on double-sided tape to the right side of the case. I have specially installed given a fee I have a screwdriver and now I can’t drive yoga batteries to a critical level.
So, in parallel with the resistor with a light diode, you can connect a buzzer (buzzer) and you will know exactly about the critical thresholds.

The axis, as if looking at the charge controller board, is drawn from the NOKIA BL-6Q battery and that is the electrical circuit.

Let's take a look at how it works. The battery is connected to two contact maidanchiks, which are placed on the sides of the controller (B-and B+). On the other board, there are two microcircuits - TPCS8210 and HY2110CB.

To the supervisor's task, to increase the voltage on battery in the range of 4.3 - 2.4 volts for її zakhistu vіd overcharge and overdischarge. In the mode of normal discharge (or charge), the HY2110CB microcircuit shows voltage on the OD and OS pins high level scho troch less voltage on the battery.

The voltage is trimmed constantly by the pole transistors of the TPCS8210 microcircuit, through which the battery is connected to the charge (your attachment).

When the battery is discharged, as soon as the voltage on the battery changes to 2.4 volts, the detector overdischarges the HY2110CB microcircuit and the voltage is no longer visible on the OD output. The upper (behind the circuit) transistor of the TPCS8210 microcircuit is closed and in this way the battery is turned on in the charge.

When the battery is charging, as soon as the voltage on the battery reaches 4.3 volts, the overcharge detector of the HY2110CB microcircuit is used and the voltage is no longer visible on the OS. The lower (behind the circuit) transistor of the TPCS8210 microcircuit will close and the battery will also turn on in the voltage.

Alternative way to replace

As you can see from the diagrams, there is no need for a microcircuit to transfer information about the battery status to your devices. The output of the controller "K" is simply applied through a resistor of the highest rating to the negative output of the battery. Also, no "hidden" information can be found from the battery controller. For some models of controllers, the replacement of a constant resistor is installed with a thermistor to control the temperature of the battery.

Behind the rating of this resistor, your attachment can determine the type of battery, or it will turn on if the value of the required value is not the same.

It means that to replace such a battery with the battery of another virobnik, it’s not necessary to change the charge controller, just freeze the resistor, which costs between the “-” and “K” and turn on the “K” switch to the minus of the battery through the call resistor of the same rating.

Documentation for the HY2110CB chip, which is written in the controller, can be downloaded, and for the TPCS8210-.

Let's take a look, on the example e-book The LBOOK V5 is the most accurate way to know the analog of a battery with no knowledge about the attachment of a charge controller. All work is carried out in the next sequence:

• It is known that the battery is similar to a stylish phone, closest to the right one for the dimensions of that capacity. Our van has a NOKIA BL-4U. (little one on the right)
• It is worth noting that the part that was lost on the roses was stitched for soldering a new battery, and the part that was missing was stitched on the old battery for stripping the conductors and rewiring with a tester.
• We take a digital tester and install it on the new mode of the world's support, between the world's - 200 Kom. It is connected to the negative visualization and the visualization of the controller of the right battery. Vimiryuemo opir.
• Vimikaєmo pridav. Shukaєmo the resistor closest to the nominal value. Our vipad has 62 coma.
• Solder the resistor between the negative leads of the new battery and the wire to the output of the controller on the socket. (Zhovty see the little one).
• Solder the rosettes to the roses "+" and "-" to the plus and minus points of the new battery. (Chervoniy and black droti on the little one).

Yet another article about the entire TP4056 microchip, which has already won a lot of money and was repeatedly protested by the army of radio amateurs. That one, before me, was sensitive about the miraculous microcircuit. Zamoviv from the Chinese five piddoslednyh, starting to guess, how to choose - overhanging or on the Khust. Here, the zvichaynіsіnka circuit is a smattering of details and the microcircuit itself.

Here, my hand was squandered by pieces of textolite and virishiv zirati on other boards, but not everything is so simple. I have seen the cartridge in a few dozen refills. It has become necessary to buy a new one, but the price of the new one is superficial, like for me. Just one day, paint with nail polish, but don’t give me more polish, they said that the lacquer was not bathed so that I stained yoga on like plaques, it’s not a friend’s pardon, like plaques - so, not a check .. .

I sat in the corner and thought about what I should take for myself, guessing that you can paint the hustki not only with varnish, but with paraffin and with a marker, paraffin is not for me, I can only bake an egg on Great Day, and that’s not even more. Ale with a marker, the idea is not bad.

Siv for the kermo of your two-wheeled pedal motorcycle and breaking to the store for the sake of a permanent marker. I know that I should say that such a marker costs 6 hryvnia. Tse on 29.02.2016

Little bit, my method is this: make marks with a pushpin on the textolite and with a marker, like a child in magazines such a rabble.

Garazd, looked at those who continue. Having poisoned mead vitriol at a retailer, I can say that it’s the best zasib, I’ll show it out of my appearance - at my skin’s edge, I’ll only say that I’m worthy in a new price, dovgovichnist and obviously those that wine doesn’t zabrudnya all chlorine zalizo.

We solder our details: a pair of SMD resistors and two capacitors.

For testing, select the battery from the laptop battery. Well, the charge is pishov, but if you don’t charge it, I’ll take a lie, but sleep at once.

He showed early that the charge was successful, and then he hurried to school and forgot to take a picture. Good luck to you all, and for you, as always, Kalyan.Super.Bos

It is necessary to pay attention to the terminology.

Yak such charge-discharge controllers are not used. Tse is nonsense. There is not enough sense to cherubate in a row. Strum razryadu to lay down in vіd navantazhennya - skolki їy treba, stilki vono і vіzme. The only thing that needs to work when discharging is to follow the voltage on the battery, so as not to allow it to be overcharged. For whom to stop.

When tsimu okremo controlleri charge not only necessary, but also necessary for the process of charging li-ion batteries. The stench itself sets the required stream, determines the moment of completion of the charge, follow the temperature slowly. The charge controller is an invisible part of me.

Based on my knowledge, I can say that under the charge/discharge controller, it’s true to understand the scheme for protecting the battery from a too deep discharge and, on the other hand, recharging.

In other words, if we are talking about a charge/discharge controller, we should talk about lithium-ion batteries zakhistu (PCB or PCM-modules). Won Axis:

I axis also stinks:

Obviously, you should pay for the presentation in different form factors and the selection of different electronic components. In this article, we can look at options for schemes to protect Li-ion batteries (or, if you want, a discharge / charge controller).

charge-discharge controller

As if the name was so good in the court, we will also win the battle. Pochnemo, maybe, from the widest variant on the DW01 (Plus) chip.

DW01-Plus

Such a charge for a li-ion battery is used for a skin-type other battery in a mobile phone. In order to get to her, just remove the self-adhesive with inscriptions, like pasting the battery.

The DW01 microcircuit itself is six-legged, and two pole transistors are structurally placed in one case, looking like an 8-legged fold.

Visnovok 1 and 3 - the key management of the keys to charge the charge (FET1) and recharge (FET2) is clear. threshold voltage: 2.4 and 4.25 Volts. Visnovok 2 - a sensor that minimizes the voltage drop on the field transistors, for which reason the strum override is implemented. The transitional opir of transistors acts as a vimiruval shunt;

The whole scheme looks like this:

The rights of the microcircuit with marking 8205A - and є poly transistors, win the role of keys in the circuit.

S-8241 Series

The SEIKO firm has developed special microcircuits for the protection of lithium-ion and lithium-polymer batteries for recharging/recharging. For the protection of one bank, integrated circuits of the S-8241 series are installed.

Keys for protection against overcharging and overcharging should be spratsovuyut virtuously at 2.3V and 4.35V. The struma is switched on when the voltage drops on FET1-FET2 equal to 200 mV.

AAT8660 Series

LV51140T

A similar scheme for the protection of lithium single-bank batteries from protection against overcharging, overcharging, transferring a stream of charge and discharge. Implemented from the design of the LV51140T microcircuit.

Threshold voltages: 2.5 and 4.25 Volts. Another low microcircuit is the input of the strum-loaded detector (limit value: 0.2V when discharging and -0.7V when charging). Visnovok 4 is not a task.

R5421N Series

The circuit design solution is similar to the previous ones. In operating mode, the microcircuit is running close to 3 µA, in blocking mode - close to 0.3 µA (letter C for the symbol) and 1 µA (letter F for the symbol).

Series R5421N should be replaced by a few modifications that are affected by the magnitude of the voltage during recharging. Details are given in the tables:

SA57608

Another version of the charge / discharge controller, only on the SA57608 microcircuit.

The voltages, for which the microcircuit includes a jar in the form of the ovnishnіh lances, to deposit in the form of the letter index. Details div. at the table:

SA57608 is able to achieve a large strum in the sleep mode - close to 300 μA, which is higher than analogs in the highest bik (there the strum is reduced to the order of the frequency of a microampere).

LC05111CMT

Well, let's talk about it cicave solution in one of the three light leaders in the variety of electronic components On Semiconductor is a charge-discharge controller on a microcircuit LC05111CMT.

The decision was made because the MOSFET keys were built into the microcircuit itself, so only a few resistors and one capacitor were left out of the hanging elements.

Transitional opir in the case of transistors becomes ~ 11 milliohm (0.011 ohm). The maximum charge/discharge jet is 10A. The maximum voltage between the S1 and S2 leads is 24 Volts (important if the batteries are combined).

The microcircuit is produced in the case WDFN6 2.6x4.0, 0.65P, Dual Flag.

The scheme, as it was cleared, secures protection from reloading/discharging, from relocating the strum to the navantage and from the overworld charging strum.

Charge controllers and schemes to zahistu - what's the difference?

It is important to understand that the charge controller module is not the same. So, their functions to the singing world are tinkering, but it would be a pardon to call the battery module charged by the charge controller. I’ll explain at once why it’s different.

The most important role of any charge controller is in the implementation of the correct charge profile (as a rule, tse CC / CV - constant stream / constant voltage). That is why the charge controller is responsible for interfacing the charging stream at a given level, thereby controlling the amount of energy that is "poured" into the battery in one hour. Too much energy is seen in the sight of heat, so whether there is a charge controller in the robotic process, it is strongly heated.

Therefore, the charge controller should not be put into the battery (on the board for the charge). The controller is just a part of the correct charger, I will add it no more.

In addition, the fee for the zakhist (or the module for the zakhist, call it whatever you want) is not worth the charge. The fee is more than control of the voltage on the bank itself and at the time of the exit of the yogo for a distant leg, the borders are installed, opening the exit keys, turning on the bank itself from the outside world. Before speech, defend in the form of short circuit tezh pratsyuє following the same principle - with short flicker The voltage on the jar sharply passes and spratsovuє the scheme of defense against a deep discharge.

Plutanina mizh schemes zakhistu lithium batteries and control the charge of vinyl through the similarity of the spratsovuvannya threshold (~ 4.2V). Only in the case of the charge module, the external connection of the bank to the correct terminals is switched on, and in the case of the charge controller, the switch is switched to the voltage stabilization mode and the incremental decrease in the charging stream.

Inspectors themselves attach the box. І schob better razіbrati tsiu topic, it is necessary to practice with a singing butt. That's why we look at the battery charge controller. What is vin? Yak vlashtovannyh? What are the features of the robot?

What does a battery charge controller do?

Vіn to serve in order to cater for the renewal of energy expenditures and vitrates. A bunch of wines are occupied by the transformation of electrical energy into chemical energy, so that a little more for the obviousness it was necessary to supply the necessary schemes for fittings. Zrobiti battery charge controller with a hand is not foldable. Aleyogo can also be played with life, which is good.

Yak vlashtovanny controller

Well, there is no universal scheme. Ale richly someone who has two triangular resistors in his robot, yak regulate the upper and lower between the voltages. If it is not possible to go beyond the given framework, the interaction with the relay windings starts, and it turns on. As long as it works out, the tension does not go lower than the song, technically behind the distance of the transfer of the raven. Here we should talk to the one who has a different range of cordons. So, for a battery, there can be installations of і three, і p'yat, і twelve, і fifteen volts. Theoretically, everything depends on the hardware implementation. Let's take a look at how the battery charge controller works in different situations.

Yakі buvayut tipi

Next, designate a significant difference, which the battery charge controller can boast of. Let’s talk about them, let’s take a closer look at the fallow classification:

1. For inspirational energy sources.
2. For post-button technology.
3. For mobile outbuildings.

Well, the sights themselves are much larger. Ale oskіlki mi rozglyaєmo controller battery charge іz zagalї point of dawn, we vystachitі і їх. If you are talking about those that stop for wind turbines, then in them the upper voltage boundary will sound up to 15 volts, then the lower one will be 12 V. With this, the battery can generate 12 V in standard mode. . What will happen if the battery voltage exceeds the installed 15 V? At the time of the controller, the contacts of the relay are closed. As a result, the power supply from the battery is switched to the energy ballast. Next, designate what you don’t like to put for sleeper panels through singing side effects. And the axis for them is obov'yazkovimi. Pobutov technique that mobile attachments may have their own peculiarities. Moreover, the controller for the battery charge of the tablet, touch and push-button style telephonesє practically identical.

A look into the lithium-ion battery of a mobile phone

If you break apart the battery, then you can remember that it is a little soldered to the whiskers. Vaughn is called a zakhistu scheme. On the right in that which requires constant control. The primary circuit of the controller is a miniature board, on which the circuit is based, built from SMD components. Vaughn's line is divided into two microcircuits - one of them is keruchoy, and the other is vikonavchoy. Let's talk in more detail about a friend.

Vikonavcha scheme

Vaughn is based on Zzvichay їх two. The microcircuit itself can have 6 or 8 turns. For separate control of the charge and discharge, the middle of the battery has two field-operated transistors, which are located in one case. So, one of them can be switched on or switched off. Another transistor to rob qi f dії, but also with a life-timer (like yogo performs charger attachment). Zavdyaki such a scheme can be easily injected into the battery's work. For the bajanny it is possible to speed up in another place. Ale slіd vrakhovuvat, scho scheme of the controller to the charge of the accumulator and vіn itself can zastosovuvatsya only to the outbuildings and elements, so that the range of operation can be closed. More details about such features will be discussed at once.

Zakhist reload

On the right, if it is possible to overvoltage 4.2, then you can blame the overheating and vibrate. For which one, such elements of microcircuits are selected, so that a charge can be applied at the reach of this indicator. І ring until the voltage reaches the indication of 4-4.1 V through the vikoristannya or in the process of self-discharge, further charging will be impossible. This is an important function, as it is put on the charge controller of lithium batteries.

Zakhist in reloading

If the voltage reaches a critically small value, as if to disturb the problematic functioning of the add-on itself (call the range 2.3-2.5V), then the active MOSFET transistor will be activated, which is responsible for supplying the stream to the mobile phone. Dalі vіdbuvaєtsya transition at the sleep mode with minimal spodzhivannyam. І here є dosit cіkaviy aspect of work. So, until the voltage in the middle of the battery becomes more than 2.9-3.1 V, the mobile device cannot be turned on for work in the sound mode. Literally, you could tell that if you connect the phone, you will show that it is charging, but you don’t want to get in and function in the normal mode.

Visnovok

Like Bachite, the Li-Ion-battery charge controller plays an important role in the security of practicality of mobile devices and positively influences the term of their service. The beginnings of simplicity in their production can be known practically from any phone or tablet. As soon as you will be on the vlasnі eyes, and with your hands touch the charge controller of the Li-Ion battery and yogo vmіst, then when sorting out the next memory, that the robot is carried out with a chemical element, then the next step is to take care of it.
