BQ76940: Serial connection for 26 cells battery

Part Number: BQ76940
Other Parts Discussed in Thread: TIDA-01093, BQ76930,

Hello.

I need BMS protection and balance board for 26 cells battery.

Could you tell me, can I connect two BQ76940 in series like BQ76930 in your Industrial Battery Management Module TIDA-01093 ? May be you have example schematic for series connection BQ76940.

Thank you.

With best regards, Alexey Gubkov.

Hi Alexey,

Please note that the BMS engineers are presenting this week during our yearly BMS Deep Dive in Dallas and may not be able to answer quickly to your question. Thank you for your understanding!

Please check out more information about this event here in case you want to join next year.

hi Alexey,
We do not have a 26s reference design but you can certainly get inspiration from the TIDA-01093 to build your own BSM for 26s with 2 BQ76940.
