BQ79731Q1EVM-060: Insulation resistance measurement

Mikael Troberg

Part Number: BQ79731Q1EVM-060

BMS060 evaluation board includes the insulation monitoring function. Anyhow the is no sequence and formula in the EVM user guide how to actually calculate the insulation value out of the measurement.

Basically I can calculate it but it would be good is the would be some formulas for the values used ready. Are those explained in some other documentation?

Hi Mikael,

I have granted you access to the "BQ7X61X-Q1_DEVELOPMENT" folder in mySecure. You should be able to view the folders' contents in ~1 hour (once the system refreshes). We have an insulation resistance calculation tool for the BQ79631-Q1 (generation before BQ79731-Q1) within this folder that should be able to help. The logic in this document should still apply to the BQ79731-Q1.

Best Regards,

Julia Louis
