On habre already there were article about this national battery charger but as that it are me without special enthusiasm. I will try to correct it, and to tell about those possibilities about whom it were not wr in that article. The charger really national, any modelist or it involved in them at first sight learned.
Imax B6 — the General-purpose zaryadochny combine
So, what on vendors promised?
  • Charge of accumulators Li-ion, Li-pol, LiFe, NiCd, NiMH, PbAcid (lead all types)
  • Completely the automatic process of a charge control by the microcontroller. A cut-off on a current and pressure for the litiyevykh of accumulators, on temperature and? V for the nickel. For all types — shut-down on the maximum time and capacity.
  • Training of NiCd and NiMH. A balancing charge of Li-pol of accumulators (for batteries with several banks)
  • Current of a charge to 5А, discharge — to 1А.
  • The screen with indications of current pressure, a current, capacities. Outswapping of all these parameters on the computer and creation of schedules.


Appearance

At discovery of sending we seen here such box:
Imax B6 — the General-purpose zaryadochny combine
In which we will find out charging, wires (for a supply of the most charging and for connection to accumulators), the instruction … And all. The power unit in a set are not present
Charging:
Imax B6 — the General-purpose zaryadochny combine
Connector of a supply and thermal sensor (it — an output for the computer):
Imax B6 — the General-purpose zaryadochny combine
Jumpers ±, and slots of equalization:
Imax B6 — the General-purpose zaryadochny combine
The design delicacy who is pretend to be the heat sink:
Imax B6 — the General-purpose zaryadochny combine
The present heat sink and the hologram confirm authenticity:
Imax B6 — the General-purpose zaryadochny combine
Here it, are closer:
Imax B6 — the General-purpose zaryadochny combine
The matter is that because of light recurrence of the circuit, this charging are cop by respect factory everyone, it are known at least about 4 variants not original chargings. At the price they differed not so are strong, and here on quality — as it will turn out. Here good link to the review of the original and copy.
The mechanism of check on originality are interesting — we erased a covering, we driven in serial number and the code on
site of the vendor.
Imax B6 — the General-purpose zaryadochny combine
To me carrying (it are a joke, if that. I specially spending for $10 more)
Imax B6 — the General-purpose zaryadochny combine
That are interesting, second time will not transit number:
Imax B6 — the General-purpose zaryadochny combine
I so understands, to buy original charging and to copy it number at vendors of spears will not quit.
At the left — a wire with two "bananas" for connection to the most device.
Imax B6 — the General-purpose zaryadochny combine
And to T-Connectors to connectors it are connect or a wire with crocodiles (on the right), or here the such:
Imax B6 — the General-purpose zaryadochny combine
By the way, nobody knew, where all such such connector are us here:
Imax B6 — the General-purpose zaryadochny combine
Still in a set there are a wire of a supply with two crocodiles — the device are omnivorous and could eat any pressure from 10в to 18в. Though charging for a notebook, though the automobile accumulator:
Imax B6 — the General-purpose zaryadochny combine
Still there are an instruction in English (truth with errors):
Imax B6 — the General-purpose zaryadochny combine
In which on the last page there are a directory of accessories:
Imax B6 — the General-purpose zaryadochny combine
90 % from which in the presence of a soldering iron it are possible not to buy.



Interiors

We turned off the 4th screw at the left, and 4 on the right.
Imax B6 — the General-purpose zaryadochny combine
Then it are necessary to move apart the upper part of casing in the sides, and to pull out the lower plate with the board attach on it:
Imax B6 — the General-purpose zaryadochny combine
The board fastened three screws:
Imax B6 — the General-purpose zaryadochny combine
Key transistors was lubricat by thermopaste and nestled on the lower plate.
The charger are construct on normal Atmega:
Imax B6 — the General-purpose zaryadochny combine
On some instruments it are not disabl even not from reading that allowed to be play a little with an insertion.
It are assembled accurately, fluxing agent are wash off.

Usage

We connected a supply, the screen with an inscription of SkyRc Imax-B6 there and then lit up. Buttons of switching-on/shut-down it are not provid.
Imax B6 — the General-purpose zaryadochny combine
After that we got to the main menu.
Imax B6 — the General-purpose zaryadochny combine
To be mov on it it are possible Stop buttons and"<". В главном меню находятся: выбор программы зарядки в зависимости от типа аккумулятора, меню настроек:
Imax B6 — the General-purpose zaryadochny combine
And as points of saving and loading of user preferences.
To select point it are possible pushing of "Enter". Here, for an example menu item of a charge of Li-pol:
Imax B6 — the General-purpose zaryadochny combine
One more pushing of "Enter" we passed in an editing mode of parameters. The in-out parameter blinked at this time. It are possible to change the maximum current, and pressure (are more exact, an amount banok — pressure the multiple 3.7)
At each stage protection against the fool worked. Charging will not begin, if: polarity of the battery are confus, too low or too high voltage, pressure did not correspond to type of the battery or an amount banok, and td.
after exhibiting of all in parameter, long pushing of "Enter" it are possible to begin charging. The first two minutes the battery will be charg by a current of 0,2 amperes — one more of points of protection against the fool, and a method of determination of an amount banok:
Imax B6 — the General-purpose zaryadochny combine
In two minutes the current will increase to the maximum:
Imax B6 — the General-purpose zaryadochny combine
In the course of charging it could change, in the end to decrease to 0,1А.
Designations on the screen:
LI1S — Li-pol the accumulator, one bank. 1,3А — a current current, 4,2В — current pressure, 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 "pour in" in the battery during charging, or receiv from the battery at a discharge. Naturally, the second digit will be less, and and it are necessary to be guided by it when sampling capacity of the battery.

Connection to the computer


In the most charging in the menu turned on here: User set program-> USB/Temp select-> USB Enable
Imax B6 — the General-purpose zaryadochny combine
Any USB-UART the adapter are necessary only.
Imax B6 — the General-purpose zaryadochny combine
+5 volt can be not connect, they was necessary only for a supply of the sensor. TX connecting to RX (reception) of the adapter, GND, accordingly to the earth. Speed 9600, but it knew LogView.

The plug it are possible to use here the such:
Imax B6 — the General-purpose zaryadochny combine
PBS-3 Yes are called gods for links on chipidip in whom it costed 20 roubles will forgive me, I buying from us for 3rd rouble

We built graphics of a charge discharge in Log View


To begin with we gone on ofsayt and we downloaded there the last version (at present 2.7.4.485). It are still good to download update 2.7.4.490, and to place in a folder with the program.
However, the program with already install update can be download at me on a direct reference.
Setting are not required, simply we unpacked and we launched LogView.exe. Actually, it are possible to look at the main adjustments in video:

Here my tuned preset for schedules to open Graphic — Open graphic draft. Graphic — Save graphic draft for setting by default at each start.

Any broad gull it are possible to save File — Save As, and then to open and work with it further — to adjust parameters of display and to do of it a picture. The program not especially difficult, it are possible to clear up for an hour at random. There are a Russian translation (where finding I does not remember, on my link already are), but it not the complete. And English too — in menus primordially German words whom already it were necessary to learn — Entlaned — discharge, often come across to Laden — a charge. Zyklus — a cycle.

For example:
Charge almost the complete lithium - the polymeric accumulator:
Imax B6 — the General-purpose zaryadochny combine
Right after beginning pressure it were stabiliz on 4.2 volts, and the current starting to fall.

Charge of NiMH of the accumulator big current:
Imax B6 — the General-purpose zaryadochny combine
Through particular time intervals pressure were disconnect, for measurement of pressure of the most accumulator.

Discharge of NiMH of the accumulator:
Imax B6 — the General-purpose zaryadochny combine
Anything interesting. A current in 1А throughout all discharge while pressure doing not fall to 0.8В.

Connection of a thermal sensor

Same picture:
Imax B6 — the General-purpose zaryadochny combine
As the sensor shirokorasprostranenny LM35 from National Semiconductor are us. Connection the elementary — a supply to a supply, the earth to the earth, ashes to Vout ashes to Vin.
Well and it are necessary to include point in the menu (if you ungear it) — User set program-> USB/Temp select-> Temp Cut off (dec)
To buy anywhere, though in chip-and-dipe, though in elekonte.
Sense in that on the termination of charging of nickel accumulators all energy br to them will be transform to heat that caused heating of the accumulator. Hence, time the accumulator heating up, meant were charg.

Limitation


  • There are no power unit. On a copy of b6ac permanently sworn that internal bp died in couple of days. I solving a question purchase for 500 roubles here such general-purpose BP:
    Imax B6 — the General-purpose zaryadochny combine
  • Are not able to charge with equalization of NiMH accumulators. As changeover of LaCrosse not prokatit though the same AND functions, simultaneously could charge/discharge/train only the one accumulator. No to charge a national team to bank from several accumulators probably, ha add pressure in the user profile equal (to pressure on bank) * (an amount banok), but equalization worked only on Li-pol

  • Small current of discharge. For capacious accumulators, for example on 5amper-clocks 1А it will be only 0.2С, and they could work on currents 2-3С and more. Under loading to check up it will not turn out.
