is there any way to detect the Battery chemistry, whether it's Lead acid or LFP? Is there any IC that can detect the Battery chemistry?

I am working on Smart charger for Multichemistry battery charging. I wanted to detect the Battery chemistry and change the charging profile according to the Battery chemistry.

Please suggest the way to detect the Battery chemistry whether it's Lead Acid or LFP. Is there any IC available for the same.

I was thinking about the Internal resistance measurement can differentiate the battery chemistry but i am not sure about the reliability.

    Hi Shivam,

    We don't have any ICs that can do this automatically. Our ICs are designed to support multiple battery chemistries, so they support different cell voltages and discharge slopes, but we don't have a way to determine the type of chemistry. If you find a way to do this and share the specific specs you'd need to measure, we'd be happy to let you know which ICs can provide the data you need.

    Best Regards,
