Other Parts Discussed in Thread: BQ76PL455A-Q1, EMB1428Q, EMB1499Q, BQ76PL455A

Hello, 

I want to make my BMS for Electrical ATV (ALL TERRAIN VEHICLE) . After our college hours we are doing all this stuff and BMS is new for us so please help us how we can make hour BMS with the help of following-

1 .BQ76PL455A-Q1,

2. EMB1428Q,

3. EMB1499Q

please sir provide some reference that how we can make our own hardware .

Our battery specifications are as following- 

1. 144AH lithium-ion battery it consist  3.7Voltage , 72AH cell of lithum - ion (total 32 cell- 16 in series).

please sir guide so that we can rapidly make our BMS  with the help of above ICs and hardware and software (which should we use for my application ) . 

Sincerely,

Tarun Singhal

  • Hi Tarun,

    Please look through the technical documentation for the bq76pl455A, and refer to the example code to work with it.

    You can also refer to the TIDA-00717 for a pl455 based reference.

    If you are doing active cell balancing, i highly recommend studying the EMB datasheets, as well as the EM1402 EVM and TIDA-00817. This will give you a good hardware starting point.

    If this is your first BMS I strongly recommend reading through the documentation, it will save you headaches down the road.

    You will also likely need a current sensing solution and MCU to work with. Our EM1402 Example code was written on the TMS570LS04X launchpad.

    Good luck!
  • Thank you sir for Reference But one more help I need -

    - If I want to make a BMS circuit with the help of bq76pl455A ic and above TI ic So, I need a simulation software which is usful  specially for BMS designing and which is compatible with TI IC's .

    sincerely ,

    Tarun Singhal

  • Hi Tarun,

    For simulation, you may look at TINA- TI, which is freely available and has many TI IC's. Due to the complexity, these parts do not have SPICE models available, unfortunately.
  • Hello Sir,

     Sir if  I want to do active cell balancing or passive cell balancing  and for that if I  use following components -

    1. bq76PL455A-Q1

    2. EMB1499Q 

    3. EMB1428Q  

    4. Some  power Mosfet and some elements 

    My Query is -

    1.Is there is any requirement of Mocrocoller for controlling of bq76PL455A-Q1 or bq76PL455A-Q1 will work itself

    2. And if bq76PL455A-Q1 work itself then how to configure bq76PL455A-Q1. Mean all configuration of Threshold voltage for start cell balancing and stop cell               balancing . Which hardware require for its configuration.After sensing all cell Voltage from Vsense pin How bq76PL455A-Q1 send controlling data on                     Equalizing   pin.

    3. If bq76PL455A-Q1 require microcontroller then which microcontroller is good for passive cell balancing as well active cell balancing  16 li- ion cell 72Ah , 48 Voltage . 

    We are college student and we are making A Electric ATV( All terrain Vehicle) And in which we want to make our own Battery Management System  with the help of Ti Components 

    Sincerely ,

    Tarun 

  • Hi Tarun,

    The bq76pl455A requires a UART peripheral to  communicate (default is 250kbaud). The EMB chipset requires  a SPI interface, which can be provided by the MCU or bit-banged with the pl455A GPIO.

    The  bq76pl455A is configured with  register writes by the MCU

    The TMS570 or C2000 are popular choices.
