    I started getting into DIY recently but I always thought or hoped of a Indian DIY channel by someone and finally found you. Keep more DIY stuff coming up it would be if it is more on electronics though :p Thank you.

    Amazing.
    Please clear we always connect parallel cells with series so how the BMS will control parallel cells to overcharge , over discharge etc . For example 3s 4p battery pack .

    Thanks for sharing your knowledge
    I have questions with respect to cell balancing please help me
    1.when this cell balancing will occur is it when charging the battery or when any cell goes more then rated voltage.
    2.can you please explain how changing in battery will happence
    3. please explain how this scenario works
    Suppose a battery contain 4 cell in it
    0v is minimum 5v is maximum
    3.5 is the normal operating voltage
    If one cell goes to 1.5v and am using passive cell balancing method and remaining cell are at 3.5 voltage
    Please explain when charging will happence and when cell balancing will occur

    • @DIYININDIA
      @DIYININDIA  4 года назад +1

      1. When cell goes more than 4.2v its ic dwo1 cuts off that cell
      2 . To change entire battery just desolder and resolder the entire battery
      In order to replace any single cell just complete one charge discharge cycle
      3. Thier is individual cell monitoring not the battery pack as a whole so this problem won't occur in the first place
      So it is certainly a problem with passive cell balancing thats why individual cell balancing is used in BMS boards
      However if your cells are totally identical which is very rare then they won't drift apart much.
      However i would have to say your questions were really great...

    Sir this video is Crisp and Clear nice video. Kindly clarify my doubt. How to identify BSI and BTEMP on battery protection board ( batteries ). Some batteries are written as P- ID TH P+ in some battery protection board written as P+ SCL SDA p-. Please let me know what is SCL and SDL on battery BLP571

    • @DIYININDIA
      @DIYININDIA  4 года назад

      SCL is the clock and SDA is the data line used to connect to an external microcontroller this is the I2C communication protocol.
      For the information about bsi and btemp refer to the datasheet of the board...

    • @DIYININDIA

      Internal resistance of 18650 is too high
      It's not designed for such high current applications
      You will be degrading the battery by doing so

      Bms are designed on pcb for application specific tasks and does the following as mentioned in video.
      To design own customised Bms, industries use the specific ics according to thier requirements from several brands like ti or vishay and sometimes even fabricate the entire board ground up....

  • @santigiri1051
    @santigiri1051 5 лет назад

    A BMS is having 3 point , namely B-, P-, & C-. C- & B+ve is for charging port, P- & B+ve is for discharging/power port and B- connected to Battery pack -. But I purchased one BMS which is having only B+ve and PACK-, the single port come out for charging and discharging/power as I presume. Another point B- is connected as usual to battery -ve. Will you pl clarify the single port can make is both for charging and discharging?

    • @DIYININDIA
      @DIYININDIA  5 лет назад

      Yes it is possible to have a single port but that is not a very good bms as it only offers balance charging but no over current or low voltage protection.
