Other Parts Discussed in Thread: BQ78350, BQ34Z100-G1
Hi~
I have developed E-BIKE so far.
We developed a battery pack for 10S (42V).
And, I have developed using BQ76930, BQ78350 and BQ76220 IC.
Now I have to proceed with a new project.
If possible, I would like to develop using TI company's IC, which I used a lot. My new project is E-SCOOTOR.
This product operates at 20S (72V).
So, I am looking for a solution for 20S.
I would like to use two BQ76930 and two BQ78350s.
Also, we are going to use MCU to control CAN communication and BMS.
Here, I saw a sample using two BQ76930 and MCU to make a 20S battery protective circuit. However, it was not seen using two BQ78350s.
The reason why I want to use 2 BQ78350s is because of SOC. I want to use BQ78350 because it is very difficult to get SOC.
1. Is it possible to use two BQ78350s?
2. What would be a good way to make 20S (72V) BMS? Ask for a smart answer.
(The previously developed samples seem to be developed using LINEAR's MONITORING IC a lot. I would like to develop it as a solution from TI company.)
3. If you have a sample example of 20S BMS, please introduce it.
Thank you very much.
