Hello sir,
(18650 Lithum) 3S or 4S or 5S Battery Managemet Control System which is active balance, have to design with buck-boost topology and investigate SOC, SOH, Temprature and also protect voltage and current etc.
I mean, I should order in your page that EVL243-R00A Active balance card, MP2790 AFU, MPF 42795 Fuel Gauge and then dowload MP2797 I2C GUI program in your page and start to design my project.
Basicaly, i prepared in paint that attached you file.
What do you think about my Project? What’s your opinion? Thats mind is true or not ? and also could our suggect on me MCU for this design? Before order I want to take your opinion sir
İ wil be happy if you help me sir
Thak you sir
Sincerely
Hello, apologies for the delayed response here.
I think this design leads in a good direction. The MP2790 is a great candidate for the 3-5 cell Li-ion packs and supports the integration of active/passive balancing and protections.
The MPF42795 adds accurate fuel gauging via coulomb counting alongside a voltage-based SOC.
In addition, the EVL243-R00A is a great way to prototype before committing to a PCB.
I would recommend an I2C capable MCU that can communicate with the MP2790 and MPF42795 that can access GPIO for protections and UART/USB for host communications. Perhaps consider something like the STM32F0/F4 series.
There should also be a DC/DC regulator IC in our block diagram such that whatever load receives a regulated voltage. Perhaps an MPS buck-boost would supplement this design.
Do let us know if there are any updates to this design and if you still need assistance.
Best,
Krishan
