Power supply IMAX B6 with your own hands. Power supplies. LIPO compatibility devices

For many TUGNIGY AccuCell and IMAX charging devices, you need to purchase a power supply that you need to connect these devices to a standard outlet. Usually the power supply is not included, and it must be purchased separately. The exceptions are only models in which the power supply is built-in; Most of the charging device models require the purchase of the block to separate.

Features of power supplies

So I made a diagram and selection of the charger. Basically, I desarmed on the registration of the scheme, the sector turned out so-so. True, the quality of the wiring and in the original does not shine. I am not a very interesting original layout, because I consider the alteration of all the sector.

There are small differences from the original, because I was too lazy to draw. I did not draw a USB port, and quartz. For a long time I already sit on Pic24, there Quartz usually do not need a nafig.

I ask for help on passing a normocontrol according to GOST in the design of the scheme (PDF, P-CAD2006). Where are there shoals (except that the numbering of components is not in order)? He killed a lot of time on the design, literally each component redrawing from his library. It turned out beautiful, but I also want more beautiful. For comparison, whose scheme IMAX B6. Normocontrolle pictures in the post do not need, in the pictures there may be an old version.

Here is still sealing (also P-CAD 2006)

The list of elements is still no, almost all the nominations in the diagram.

And now I will tell you how the scheme works. She is very interesting.

1. Protection against meals

Protection is made on the N-channel MOSFET transistor. Such a solution allows you to provide almost zero voltage drop, compared with the protection on the diode. For example, at a current of 3a 12V, the diode would be quite warmed, more watt.
This scheme has a small drawback: for high voltage, more than 20V, the R6 resistor must be replaced with a 10-volt stabilion.

2. DC-DC converter
For the work of the charger, you must have adjustable source Nutrition. Source capable of 12 in Make both 2B and 25B. Here is its scheme:


The converter is controlled by three lines:
1) DCDC / ON_OFF line is a prohibition of the converter. Feeding on line 5V, it turns off as VT26 (key for STEP-UP mode) and VT27 (key for STEP-DOWN mode).
2) STEPDOWN_FREQ dual-purpose line: in Step-up mode on this line there should be 5V, otherwise the power to the L1 coil does not arrive, the frequency should be on the STEP-DOWN. Adjusting the diversity by changing the output voltage.
3) SETDISCURR_STEPUPREQ line. In an increase in the mode on this line, PWM, in down - 0v
Additionally, the protection from the KZ through the battery line is implemented: when the charging current is exceeded, VT8 will work, and the power from the converter will be removed, the VT26 transistor will open. As it works exactly, I did not figure it out, you can seek the scheme yourself.

Question hall: What do R114 + R115 + C20 do?

Power MOSFET keys VT26 and VT27 are controlled by a two-stroke, emitter repeater: VT13-VT14 and VT17-VT18.

The frequency of the converter of 31250kHz.

This converter cannot be turned on without minimal load, which is R128. Moreover, in my version of charging, it is soldered by the attack, it is on top of other elements - the developer error.

3. Turning on the battery

No battery output is connected to the ground directly. This concerns both the power chains and the balancing connector. Plus the battery is connected to a DC-DC converter, minus to the charging transistor. By turning on the Charge Transistor, as well as adjusting the voltage on the DC-DC, the required charging current is installed.

4. Protection against fool when reselling the battery


The inclusion of the charge is controlled by DA4.2, and the charge is only when proper connection battery. To prohibit the charge may also controller, VT9 transistor.

5: discharge scheme


The discharge scheme is built on the VT24 transistor and two operatingors. To turn on the discharge you need to open VT12. VT24 is a discharge transistor. It is he who disperses heat when discharge. Manages them two operating amplifiers.
Sending to the input of the two RC chains of Meander,


the controller generates voltage to IN + DA3.2:

DA3.2 is an integrator scheme (filter low frequencies). It will increase the output voltage (and on the shutter of the discharge transistor VT24), which means that the discharge current until the voltage at the In + and In- (red chains) conclusions are equal. In + is a reference signal from the controller, on the signal from the circuit feedback on DA3.1. The result - the current smoothly increases to the nominal
Brown wire - ban discharge. If 5 volts are on it - the discharge is prohibited.
On the blue line, you can check the actual discharge current.

6. Balancing and voltage measurement scheme on cells


How, for example, measuring the voltage of the sixth cell? The Bal6 and Bal5 voltage with the sixth cell is supplied to the DA1.1 differential amplifier, which out of 25V on the sixth cell subtracts 21B on the fifth. At the exit - 4B.
Bottom cells are measured without the participation of the differential amplifier, the divider. Especially note that even the "earth" is measured (BAL0).
The output is communated by the HEF4051BT multiplexer on the controller. Without a multiplexer - in no way, there is not enough legs.

Balancing diagram is made on two transistors. With regard to the sixth cell is VT22 and VT23. VT22 - a digital transistor, there are already built-in resistors, and it is connected directly to the controller output. If the microcontroller notices that some cell is recharged, it will stop the charge, turns on the corresponding recharged cell circuit, and the current will run about 200mA through the resistors. As soon as the cell discharged a little, the charge of the entire battery battery is turned on.

7. Digital chains


The controller measures the voltage controller on the plus and minus battery. If the ransom will occur - a warning will be displayed on the screen.
The illumination of the indicator is necessary for some reason from the transistor, the indicator itself is enabled in a 4-bit mode.
Another interesting is the TL431 reference voltage source.

Another question for the category of quartz: Is quartz required for ATMEGA?

I received a new IMAX B6 mini, in which both changes and additions occurred. First of all, the changes affected the fan of the device and wires, the fan now costs more quiet and, as the manufacturer assures, reliable. Wires have become more rigid and better, connectors for connecting AKB to IMAX B6. Next, the changes affected the firmware itself and, accordingly, the functional.

Now IMAX B6 mini began to maintain high-touch lithium batteries, plus appeared new opportunity In the settings, disable or enable charging lithium batteries With a balancing overview or without, with the exhibition of the ceiling for stresses.

Now in the new chargers of the IMAX B6 series mini in the characteristics about their errors, my IMAX B6 mini error was only 0.02 volts that I think it is not bad for the device that you get out of the box. With such an error, the IMAX B6 calibration is not needed.

To connect IMAX B6 mini to power from the network, you can use any power supply with a supply voltage from DC 11.0-18.0 volt, I recommend limited by the limit in the DC 12.0-17.0 volt range. If you use the power supply 2a, then the maximum charge current is better to choose in the area to 1 A to reduce the load on the power supply.

I recently asked me, but you can connect IMAX B6 mini to a stationary computer through the power supply. The answer can be: provided that the IMAX B6 mini will not be on system block, like the battery, so that the short circuit did not happen.

When using power supplies 12-16 volts 5-6A, there is no charge restrictions, but the smaller from the current of the current you will charge the battery, the smaller the chance of overheating, which means the IMAX B6 mini device will last longer. Problems with the original IMAX B6 mini me were not seen.

Well, in contrast to the original IMAX B6 mini there is the ability to connect to a computer via USB mini. How to connect to a computer IMAX B6 mini can be viewed in this topic.

IMAX B6 is suitable for different types batteries. A modification is controlled by high-quality microprocessor. This model stand out wide range Circuit current. It is also worth noting that it provides a limited charge function. The input voltage is continuously monitored.

If we talk about the characteristics of charging, then the minimum voltage is equal to 10 V. Power is at 60 W. The minimum current of the discharge at the modification is 0.1 A. It is also worth mentioning about compact sizes Devices. With a length of 133 mm and a width of 87 mm, the model has a thickness of only 33 mm. It is worth a modification in the markets approximately 1500 rubles. However, you can make IMAX B6ac with your own hands.

Charging scheme

The standard charging scheme includes one microprocessor, a module, a kotroller and an expander unit. It is also worth noting that in original version Varicap is used. It monitors impulse fluctuations in electrical chain. For compatibility with batteries, the capacitor is answered. Thyristor is applied to two adapters. To protect the charging, insulators of different conductivity are used. One filter is installed at the input, which runs from the amplifier. It is also worth noting that the charging has a rectifier. And it is part of the expander.

Make a block for charging

Make a power supply for IMAX B6 with your own hands is quite simple. First of all, the transformer is selected. Distoror for these purposes is allowed to use low-frequency type. To overcome high sensitivity, three filters are installed on the plug. Then, to make the power supply for IMAX B6 with your own hands, the amplifier is taken. The specified element operates at a voltage of 15 V. The limit frequency at the same time equals not less than 55 Hz.

Installing balancing connector

Under the IMAX B6 balancing connector can be done different ways. The most often experts are used for this linear adapter. Start the soldering is from the comparator. It is installed behind the expander and is an integral part. During the work, negative resistance is checked. This parameter in a normal model is approximately 50 ohms.

The second method of assembly lies in the installation of the grid adapter on IMAX B6. Balancing connector with your own hands solder problematic. The adapter is quite difficult to get. However, it has a lot of advantages. First of all, it is rarely overheated. Also, the element is durable. In addition, it has good conduct.

Thermal sensor for modification

Make a thermal sensor for IMAX B6 with your own hands using the capacitive trigger. First of all, when assembling, the modulator is harvested expedient to apply the contact type. Next, to assemble for IMAX B6 with your own hands, you need to use the phase comparator. It is installed behind the filter. In this case, the adapter will be required on inverter transistors. Their conductivity should be not lower than 45 MK.

Modification by 10 V

Charging IMAX B6 is going to charge with your own hands (the photo is shown below) is quite simple. During the work, it is important to choose the right condenser. It affects the overall performance of charging. In the original version, a wired microprocessor is used. To install it, you will have to use the transceiver, which is attached to the board through the port. It is also worth noting that at the output of charging should be voltage not more than 8 V.

Many specialists suggest that field type capacitors are better not to use. To reduce thermal losses, transition filters with conduction from 4 MK are used. They are not afraid of increased frequency, as well as wave interference. It is also worth noting that the models this type Work in economical mode. Directly triode is mounted with a resistance of 40 ohms. The occurring for it is selected capacitive type. Directly the transducer is installed behind the microprocessor. A comparator is soldered to control the signal transmission.

Collect devices for 15 V

You can assemble for 15 in the IMAX B6 charger with your own hands on the basis of a duplex expander. However, first of all it is worth how to enchant. In the original version it is made without soldering. It is also worth noting that the model must have two filters. The charging voltage directly check the tester. After installing the microprocessor, triode is soldered.

The specified element is allowed to use on one adapter. The heat return on its average equals 89%. In this case, conductivity depends on many factors. Charging capacitors are installed with tetroles. These items are capable of working at a frequency not lower than 40 Hz. At a voltage of 15, a block turns on the operation. To reduce the frequency of modification, experts are recommended to use broadband rectifiers.

Homemade modifications for 15 V

Going to 15 in charge IMAX B6 with your own hands without conductive comparator. However, it is worth noting that the conductivity of the device will not be more than 5 microns. The main problem when assembling can be in Tetrode. It is quite difficult in our time to find the original part with a capacity of 5 PF. However, it can be replaced with a linear analogue, which is a universal element. It is calmly functioning at a frequency of no more than 5 Hz. When assembling a modification, it is worth constantly tracking the voltage.

With a sharp increase in this parameter, it is worth using a varicap. When the sensitivity decreases, you can try to replace the filters. After installing the microprocessor, the soldering of the transistor should be done. If you use field analogs, then they have a low return ratio. It is also worth noting that they are not able to work in economical mode. Working temperature Elements on average equals 45 degrees. Insulators for charging is more expedient to install low conductivity.

Devices with the output of ar

Collect (with the output of AR) The IMAX B6 charger (with your own hands) is very simple. For this, only one adapter will be required. It will connect to the expander. If we consider the standard charging scheme, then the trigger needs to be used adjustable type. Also, the modulator and microprocessor will also need to build. The converter is allowed to use two plates, and minimum frequency It should be approximately 50 Hz.

Thus, the device achieves high conductivity at low heat losses. If you believe the experts, the filters can be fixed only with semiconductors. The output voltage on the expansion should not exceed 15 V. When the condenser overheating problems are detected, it is worth considering the insulator carefully. When damaged, you can try to clean the element.

Models only with access aa

Make (with AA input) The IMAX B6 charger is a bit more complicated than the previous modification. In this case, you will have to select two channel adapters. The microprocessor is used directly by 50 Hz. To solve problems with conductivity, a comparator is installed standard. A modification converter must have good sensitivity. In the original version, it is protected by two filters that are installed on the sides of it.

If you believe experts, you can use operational analogs. These filters are not afraid of overheating. To protect the comparator, a low conductivity isolator is also used. Adapter is more expedient to use on the plane, and it follows the expander. Then it is necessary to solder varicap. Directly adapters under the connector are mounted near the comparator. With raising resistance at the exit, experts are proposed immediately replace filters. Also should believe the condition of the insulator, which is installed next to the microprocessor.

Li-Ion compatibility devices

You can make a modification with Li-Ion compatibility on the basis of an open comparator. It works at a frequency of 55 Hz and copes well with the transmission of sinusoidal signals. However, starting a modification assembly stands standard from the installation of the microprocessor. Only after that it is allowed to do an expander that is attached on the plug and connects with an electrical chain.

To solve problems with conductivity, the linear type converter can be replaced with grid analogues. They stand cheaply and are quite compact. Varicap is more expedient for charging pick on a magnetic tape. When detecting problems with sensitivity on the exploratory experts, it is recommended to check the health of the microprocessor. The problem can only be in it.

LIPO compatibility devices

Make (with lipo compatibility) charging IMAX B6 with your own hands is quite simple, but you will need a high-quality adapter for a modification. The microprocessor is installed on the plane. Many experts recommend using stabilizers. They significantly reduce the risk of magnetic interference. It is also worth noting that they are well coped with pulse jumps in the electrical charging circuit. The adapter on the modification can be installed for triode.

Thus, only one isolator will need. Filters are standardly used with conduction from 4 MK. If you believe experts, it is worth paying special attention to the nineteen, which is soldered behind the comparator. If negative resistance changes dramatically, you need to test the chain from the microprocessor. Rated voltage should be 13 VU. When conducting conductivity problems, it is always worth checking the Distoror.

Ni-CD compatibility charging

Ni-CD compatibility modifications are most often produced on magnetic modules. The extender in this case is allowed to use two contacts with no more than 55 MK. Some experts suggest that after installing the microprocessor, it is worth checking the negative resistance. It is also important to remember that the output voltage parameter during overload 3 and should not exceed 15 V. The plates in devices are allowed to use with filters.

In this case, low sensitivity transition modifications are well suited. In this case, the insulator is set for the expander. If problems occur, it is recommended to double-check the conductivity of the microcontroller. In some cases, the problem may also be in the filter. With a minor deviation of the resistance, you can try to install a comparator that will suppress all pulse interference from the block.

PB compatibility modifications

To make (with PB compatibility) Modification of IMAX B6 with your own hands, it is recommended to prepare a microcontroller on 40 Hz, as well as a diode extender. Specialists in this case do not advise to install output insulators. First of all, they reduce the sensitivity parameter of the charging.

It is also worth noting that there are certain problems with current conversion. Stabilizers on charges of all applied single-pass type. In this case, the converter should be installed behind the rectifier. In order to solve the filter problems, transceivers are used. These devices must operate at 33 Hz. The overload rate at the exit of charging should not exceed 4 A. Transistors quite often apply low-level type.

NiMH battery devices

To collect (for NiMH batteries), the IMAX B6 charger can use only one adapter with a microcontroller in this case is set to the extender. Some experts advise immediately check negative resistance in order to avoid further overload problems. Transistor for charging is set to adjustable type. Directly adapter is soldered on the edge of the comparator. In total, two filters of low capacity will be required for modification.

Amplifier is more expedient to apply with a converter that can work at a voltage of 15 V. It is also worth noting that the microprocessor can be protected only with the help of insulators. The triode in the original charging version uses broadband type. It can withstand impulse interference and shows itself well in conditions of high voltage.

Application of dynamic transceivers

How to make the IMAX B6 charger? Responding to this question, it is worth noting that dynamic transceivers can work at a frequency of not more than 35 Hz. To assemble modifications, the wired expander will be required primarily and additionally microprocessor. Filters for a model are more expedient to use a single-pass type. Some experts suggest that resistor blocks with conduction from 55 MK are remarkably suitable for devices. In this case, it is worth measuring the output voltage and check the resistance. In case of failures in the chain, it is recommended to replace the microprocessor. Charging adapter is allowed to install with a discrete switch. It is also worth noting that the charging modules are used with radiation transistors.

Using a trigger on diodes

How to make the IMAX B6 charger with your own hands? Triggers on diodes significantly increase the conductivity of the model. For self-assembly Modifications experts advise the use of condenser expander. However, the microprocessor is installed on the equipment first. It is also worth taking care of the selection of a high-quality module. To increase the conductivity of the modification, it is recommended to use analog models.

The expander is installed on the adapter. To verify the modification, measure the level of negative resistance on the conductors. This parameter should not exceed 45 ohms. The charging controller solder with the cathode. His sensitivity should be about 30 mV. Lastly, the conductivity of the expander is checked. If this parameter is more than 50 microns, then the charging will have to install a grid filter. With low sensitivity, a dynistor with an adapter is put.

Charging with linear triggers

Quite often, charging is collected on linear triggers. These elements are capable of working with increased frequency. They have a small conductivity, and the limit is 50 V. In order to collect charging, it is recommended to install a microprocessor and choose an extender. Capacitors in such devices experts are advised to be installed with passing transistor. It is also worth noting that it is always possible to solve the problems of high frequency due to channel filters.

Greetings all models.
My first parcel came recently. In it, apart from any little things, I ordered a charger. I did not immediately order the power supply under it, since I was confident that the Asus was suitable from the laptop.

This BP (like many others on laptops) has a yield of 19 V.
When I connected it to IMAX B6, the charger told me about the error: - INPUT Vol Err., And the cutting until you turn off (by the way, the cooking is not loud, the phishing has already been muffled at the factory).
Just one volt no longer wants to work!
Road BP from a laptop is a stupid, buying a new one, is expensive. I understood that it was necessary to somehow lower the voltage for one volt. How to make me suggested here two people:
Sergey Findeazen, Moscow and Vyacheslav Alferes, Smolenskwhy thank you very much!

So I needed:

• three diode 6A05
• circuit board
• connector "Mom" under a laptop connector, cord with "dad" to Imax B6 I had.

All this cost me 1.5 $.

I soldered the connector to the board and sequentially the diodes themselves, cord.

ATTENTION!
The article left as it was, tests have shown that when charging the current 1a, the diodes begin to really warm, do not repeat this design from the ceiling.

After soldering, I checked - everything works!

And began to stick the sides.

Where the wire goes to the charger, pasted scotch

And the wire itself blelled Titan well.

Pucked body.

I wanted to puncture the entire body of scotch, for beautiful view, but changed.
I will say honestly, I don't have batteries, order them at the PF is now a problem, I bought under the order in Ukraine in the online store, with overpayments almost twice. While they have not come yet. I checked my device only on finger accelerators, but suddenly when charging more powerful, the diodes will begin to warm up? Then my body from the ceiling will come to disassemble, and come up with something more practical.
in general, I decided to leave so much, I think that the battery or charging should be warm, but not diodes if I am mistaken, then I must write it here.

A few words about the charger itself IMAX B6.

I came the original as I ordered. The quality of its production on 5 with a plus. But when I started thinking how I would charge my first akki, I realized that the set did not enter the session to charge the XT60. It is a pity that the translator does not indicate that it must be purchased. I would immediately ordered myself, now I will have something to "collective me" until the next parcel will come in which I will order these connectors.
As I mentioned I checked the charger on Eneloop (ah).

I used these batteries in the camera, and charged them charging Ataba 508.

Akks are old, and charging them just won.
On IMAX B6 I chose - program Nimh batteries Using a cycler (3rd charge-discharge), exposing a current of 600mA and discharge 200mA.
In general, my "batteries" came to life, before they were enough for 30-40 shots with an outbreak, now I'm tired of clicking checking.
The result, the charger is very good!

Thank you all for your attention!

__________________________________________________________________________________________

Attention, because The disputes began about that there will be such an adaptation to work or not, and I have grown doubts about the temperature, I decided to spend a number of video experiments of which I will add here. If you're interested, write.

It was disassembled (broken) my casing from the ceiling, doped by a capacitor for 25V-470 μF. The temperature is measured when charging 2x ENELOOP 2000 MAH batteries, it was 40 °.

9.11.2013

Attention today charged the first time its LIFEPO4 battery from the transmitter, current 1a, The diodes are really warm, neither the cassette ceiling and speech can not be!
