Hello,

Is it possible to read the measured/calculated impedance during operation? If so, in which register?

Thank you in advance for your help.

Best Regards,

Hello Philippe,

Impedance values are not available for readout. The closest thing that may translate to impedance is the Ra table values. There are no details available on how to interpret those values.

that's too bad, because in many battery supervision applications, customers ask for internal resistance measurement. The Ra table could be a solution worth investigating.
Thanks for your reply.
