On Habré there was already article about this national battery charger, but as that it is met without special enthusiasm. I will try to correct it and to tell about those opportunities about which it was not written in that article. The charger really national, any modeller or involved in them at first sight recognizes him.
Imax B6 — the Universal zaryadochny combine
So, what on is promised by vendors?
  • Charge of the accumulators Li-ion, Li-pol, LiFe, NiCd, NiMH, PbAcid (lead all types)
  • Completely automatic process of a charge managed by the microcontroller. A cut-off on current and tension for lithium accumulators, on temperature and ΔV for nickel. For all types — switching off on the maximum time and capacity.
  • Training of NiCd and NiMH. A balancing charge of Li-pol of accumulators (for batteries with several banks)
  • Charge current to 5A, discharge — to 1A.
  • The screen with indications of the current tension, current, capacity. Unloading of all these parameters on the computer and creation of diagrams.


Appearance

When opening sending we see here such box:
Imax B6 — the Universal zaryadochny combine
In which we will find charging, wires (for power supply of the charging and for connection to accumulators), the instruction … And all. There is no power supply unit in a set
Charging:
Imax B6 — the Universal zaryadochny combine
The power connector and the thermal sensor (it is an output for the computer):
Imax B6 — the Universal zaryadochny combine
Jumpers ±, and slots of balancing:
Imax B6 — the Universal zaryadochny combine
The design delicacy which is pretending to be a radiator:
Imax B6 — the Universal zaryadochny combine
This radiator and the hologram confirming authenticity:
Imax B6 — the Universal zaryadochny combine
Here it, is closer:
Imax B6 — the Universal zaryadochny combine
The matter is that because of easy recurrence of the scheme, this charging everyone copies itself(himself) the respecting plant, it is known at least of 4 options not original a zaryadok. At the price they differ not so strongly, and here on quality — as it will turn out. Here good link to the overview of the original and copy.
The check mechanism on originality is interesting — we erase a covering, we drive in serial number and a code on
website of the vendor.
Imax B6 — the Universal zaryadochny combine
I was lucky (it is a joke if that. I specially spent more for $10)
Imax B6 — the Universal zaryadochny combine
What is interesting, the second time will not pass number:
Imax B6 — the Universal zaryadochny combine
I so understand, to purchase original charging and to copy its number at vendors of copies will not leave.
At the left — a wire with two "bananas" for connection to the device.
Imax B6 — the Universal zaryadochny combine
And to T-Connectors to connectors it is connected or a wire with crocodiles (on the right), or here such:
Imax B6 — the Universal zaryadochny combine
By the way, nobody knows where all such such connector is used here:
Imax B6 — the Universal zaryadochny combine
In a set there is a supply lead with two crocodiles — the device is omnivorous and can eat any tension from 10v to 18 century. Though notebook charger, though automobile accumulator:
Imax B6 — the Universal zaryadochny combine
Still there is an instruction in English (the truth with errors):
Imax B6 — the Universal zaryadochny combine
In which on the last page there is a directory of accessories:
Imax B6 — the Universal zaryadochny combine
90% from which in the presence of a soldering iron it is possible not to buy.



Interiors

We turn off 4 screws at the left, and 4 on the right.
Imax B6 — the Universal zaryadochny combine
Then it is necessary to move apart upper part of the body in the parties and to pull out the lower plate with the payment attached on it:
Imax B6 — the Universal zaryadochny combine
The payment fastens three screws:
Imax B6 — the Universal zaryadochny combine
Key transistors are greased with thermopaste and nestle on the lower plate.
The charger is constructed on normal Atmega:
Imax B6 — the Universal zaryadochny combine
On some devices it is not even blocked from reading that allows to be played a little with a firmware.
It is collected accurately, gumboil is washed away.

Use

We connect power supply, the screen with SkyRc Imax-B6 text right there lights up. The button of inclusion/switching off is not provided.
Imax B6 — the Universal zaryadochny combine
After that we are included in the main menu.
Imax B6 — the Universal zaryadochny combine
It is possible to move on it the Stop buttons and"<". В главном меню находятся: выбор программы зарядки в зависимости от типа аккумулятора, меню настроек:
Imax B6 — the Universal zaryadochny combine
And also points of saving and loading of user preferences.
It is possible to select item clicking of "Enter". Here, for an example Li-pol charge menu item:
Imax B6 — the Universal zaryadochny combine
With one more clicking of "Enter" it is passed into an editing mode of parameters. In-out parameter blinks at this time. It is possible to change a maximum current, and tension (more precisely, the number of cans — tension multiple 3.7)
Protection against the fool works at each stage. Charging will not begin if: battery polarity is mixed, too low or too high tension, tension does not correspond to type of the battery or the number of cans, and td.
after exposure of all it is possible to begin with the parameter, long clicking of "Enter" charging. The first two minutes the battery will be charged with current 0,2 amperes — one more of points of protection against the fool, and a method of determination of number of cans:
Imax B6 — the Universal zaryadochny combine
In two minutes current will increase up to maximum:
Imax B6 — the Universal zaryadochny combine
In the course of charging it can change, in the end to decrease to 0,1A.
Designations on the screen:
LI1S — Li-pol the accumulator, one bank. 1,3A — the current current, 4,2B — the current tension, CHG — in abbreviated form from Charging, a charge. 003:49 — time in minutes and seconds from the moment of the beginning of the program, 00046 — "capacity" in milliampere-hours "poured" in the battery during charging, or received from the battery when discharging. Naturally, the second digit will be less, and and it is necessary to be guided by it at measurement of battery capacity.

Connection to the computer


In charging joins in the menu here: User set program-> USB/Temp select-> USB Enable
Imax B6 — the Universal zaryadochny combine
Only any USB-UART needs the adapter.
Imax B6 — the Universal zaryadochny combine
+5 volts can be not connected, they are necessary only for power supply of the sensor. TX is connected to RX (acceptance) of the adapter, GND, respectively to the earth. Speed 9600, but LogView knows it.

The plug it is possible to use here such:
Imax B6 — the Universal zaryadochny combine
PBS-3 Yes is called gods will forgive me for links on chipidip in which it costs 20 rubles, I purchased from us for 3 rubles

We build diagrams of a charge discharge in Log View


For a start we go on ofsayt and we download the latest version there (at the moment 2.7.4.485). It is still good to download updating 2.7.4.490 and to place in the folder with the program.
However, the program with already set updating can be downloaded at me at a direct reference.
Installation is not required, simply we unpack and we start LogView.exe. Actually, it is possible to look at the main settings in video:

Here my configured prest for diagrams, to open Graphic — Open graphic draft. Graphic — Save graphic draft for installation by default at each start.

Any log it is possible to save File — Save As, and then to open and work with it further — to configure settings of display and to do of it the picture. The program is not especially difficult, it is possible to understand for an hour at random. There is Russian translation (where found I do not remember, according to my link already is), but it is not complete. And English too — in menus primordially German words which it was already necessary to learn — Entlaned — discharge, Laden — a charge often come across. Zyklus — a cycle.

For example:
Charge of almost complete lithium-pol cell:
Imax B6 — the Universal zaryadochny combine
Right after the beginning tension was stabilized on 4.2 volts, and current began to fall.

Accumulator NiMH charge big current:
Imax B6 — the Universal zaryadochny combine
Through certain periods tension was disconnected, for strain measurement of the accumulator.

Discharge of NiMH of the accumulator:
Imax B6 — the Universal zaryadochny combine
Anything interesting. Current in 1A throughout all discharging, so far tension did not fall till 0:8é.

Connection of the thermal sensor

Same picture:
Imax B6 — the Universal zaryadochny combine
As the sensor shirokorasprostranenny LM35 from National Semiconductor is used. Connection the elementary — power supply to power supply, the earth to the earth, ashes to Vout ashes to Vin.
Well and it is necessary to include point in the menu (if you switched off it) — User set program-> USB/Temp select-> Temp Cut off(dec)
To purchase anywhere though in chip-and-dipe though in an elekonta.
The sense is that on the termination of charging of nickel accumulators all energy brought to them will be transformed to heat that causes heating of the accumulator. Therefore, time the accumulator heated up, means was loaded.

Shortcomings


  • There is no power supply unit. On the copy of b6ac constantly swear that internal bp dies in couple of days. I resolved an issue by purchase for 500 rubles here of such universal BP:
    Imax B6 — the Universal zaryadochny combine
  • Is not able to charge accumulators with balancing of NiMH. As replacement of LaCrosse will not give a ride though functions and the same, at the same time you can load/discharge/train only one accumulator. No, it is possible to load the national team to bank from several accumulators, having added tension to the user profile equal (to tension on bank) * (the number of cans), but balancing works only at Li-pol

  • Small current of discharge. For capacious accumulators, for example on 5 Ampere-hours-hours will be only 0.2C, and they can work at currents 2-3C and more. Under loading to check it will not turn out.
