More info


  • This charger is a very small module for DIY people, it uses the TP4056 controller and standard configuration is with 1A charge current. It does not include any power supply or tray. It did not include any documentation either, just a couple of boards.
    The review is about a specific charger module, but any module with the TP4056 will have identical performance.

    DSC_0562 DSC_0563

    I got it in an envelope with 5 circuits on 2 boards and nothing else. The boards is precut and very easy to break apart.
    There is some documentation on the sellers ebay page.

    DSC_0635

    A close study showed that there was a small difference between the size of the boards.

    annotation

    The board needs a 5 volt power supply, this can either be from a mini usb connector or soldered directly to the board.
    The "current resistor" can be replaced for other (lower) charge currents, because it is a 0603 size smd resistor (i.e. very small) it can be difficult to replace it.
    On my boards I have a blue led for charging and a red led for done.

    The charge led will be on when charging and it will be flashing when no battery is connected.
    The done led will be on when charging is done or no battery is connected.

    DSC_0564

    The backside of the board has some internal connections and the connections points are also accessible here.

    DSC_0581

    The board is small, the battery is a AAA battery.

    With the mounted resistor the charger can handle larger batteries, but changing the resistor makes it to possible to charge smaller batteries.




    Measurements

    Below 2.85 volt the charger will charge with about 80mA in 1A configuration (blue led is on).
    Above 2.85 volt the charger is applying regular charge current (See curve below).
    When charger is disconnected from power, but with a battery in, it will draw below 1uA from the battery.
    When the charge current goes below the termination current the charging is stopped and it will charge with around 4 uA.
    The charger will restart charging when the cell drops to 4.0 volt.
    The charger will not restart after a power loss or battery insertion, except if the battery voltage is below 4.0 volt.



    ChargerTP4056%20(PS18650-34)

    First test is with a 3400mAh battery, the charger does a good CC/CV, except the change from CC to CV is a bit soft, this increase charge time but has no bad effect on the battery. The charger is also a bit below the 1A current, it only charges with 0.85A.
    The CV voltage is slightly below 4.2 volt, that is not surprising, because the datasheet for the TP4056 specify that it can be between 4.137 and 4.263 volt. This chip uses 1/10 of the charge current as termination current.
    I added a temperature measurement to the test this time, as can be seen the chip heats up fast and then slowly drops in temperature when the battery voltage increases.

    ChargerTP4056%20(PS18650-34)%20Vusb=4.5V

    Reducing the supply voltage to 4.5 volt, increases the charge time and reduces the temperature, but the final voltage is slightly lower.

    ChargerTP4056%20(PS18650-34)%20Vusb=5.5V

    Increasing the voltage does increase the temperature, but also reduces the current. When the chip gets to hot, it reduces the current.

    ChargerTP4056%20(PS18650-34)%20Vusb=5.5V%20HS

    Here I have added a heatsink to keep the temperature down (Remember electric isolation between PCB and heatsink). It works very well, the temperature is lower than with 5.0 volt supply.

    DSC_0609

    The heatsink was just a piece of aluminium under the board with some isolation between.

    ChargerTP4056%20(AW16340-IMR)

    My old 16340 IMR cell is also charged without any problems.


    Modified resistor

    Replacing the standard 1.2 kohm resistor with a 2.157 kohm reduces the charge current to 470mA.
    The resistor is a 0603 SMD resistor, i.e. it is 1.6 x 0.8 mm.

    DSC_0637

    Here a 0603 resistor is placed next to an old style quarter watt resistor.


    ChargerTP4056%20(PS18650-34)%200.5A

    Again the charger does a CC/CV charging, because the charge current is lower, the termination current is also lower.

    ChargerTP4056%20(ET16340-750)%200.5A

    A 16340 battery is a more reasonable size to charge with 0.5A.

    Replacing the standard 1.2 kohm resistor with a 4.726 kohm reduces the charge current to 210mA.

    ChargerTP4056%20(ET16340-750)%200.25A

    Again I tested with a16340 battery and get a CC/CV curve.
