All About Battery connector pinout of mobile phone

what is - BTemp ?
[All About Battery connector pinout 4mgf)
It is used to measure the battery temperature.
The phone stops the charging, if the battery is starting to overheating. In case of NTC thermistor, if the temperature increasing, the resistance decreasing. The temperature of the battery make the resistance beetween the GND and the BTemp change.
There are batteries which don't have BTemp connector. In this case, the phone has a temperature meter close to the battery.



what is - BSI ?
[All About Battery connector pinout 4mgf)
Battery Size Indicator ( or Battery Status Indicator or Battery System Indicator )
Mobile phones use BSI to identify the type and size of the used battery. This is needed to determine the current and the voltage of the charging.
It is connected to resistor to GND. The phone measures the resistance of the BSI - GND connectors, and it can determine which kind of battery is in the phone.
Nokia NiMH batteries:
* BMC-2 640mAH 3.3 kOhm
* BMC-3 900mAH 5.6 kOhm
Nokia Li-Ion batteries:
* BLB-2 650 mAH 68 kOhm
* BLC-2 900 mAH 75 kOhm
There are some mobile phones, which has shorter BSI pin. It is because when the battery is being removed when the phone is turned on, the BSI circuit interrupts first, which tells the processor to shut down all communication to prevent damage.



what is - VBAT ?

  5. Thank you so much for the enlightenment on the battery Acronym

    Please I have an issue which I would like you to help me out.

    Question 1.
    How can I connect a 3 terminal battery to a mother board that has ( GND, USB DL, VUSB, DM And Dp) Also has (VBAT, ON/OFF, GRN, RX and RT) on the same board.

    2. How can I connect a 5pin charging port to any of those mentioned points on the mother board.

    The issue Here is that, the socket point on d board for d charging port got peeled ,

    so I want to connect network wires on the 5pins on d (charging port) then take it to those mentioned points on d back of the mother board.

    A. (So that the phone could be recognised by a system)

    B. The phone could also charge without overheating and also show battery percentage.

    I will really appreciate your kind and prompt response please.

    Thank you.
