Dear Community Member,

I am developing a Battery Management System utilizing the BQ40Z80 BMS IC and Renesas RA series MCU. I am seeking clarification on whether the BQ40Z80 BMS IC suits a 7S3P battery pack configuration. Your prompt response would be greatly appreciated.

Best regards,

Neeraj

Hi Neeraj,

I believe that bq40z80 should support a 7S3P configuration as long as it does not exceed the 65000 mAh battery capacity maximum threshold.

Hi Anthony,

Thank you for your prompt response. I am inquiring about the most suitable BMS IC for a 7x3x3500= 73500 mAh battery. Your expertise in this matter would be greatly appreciated.

Thank you,

Neeraj

Hi Neeraj,

Understood, it seems like the max capacity is too high for the bq40z80. For a pack this size, I would recommend looking into the bq34z100 found below:

Please let me know whether this meets your requirements, I can offer more recommendations if needed.
