How to measure discharge current of a battery electronics using EV2300?

I have an alternate battery I am in the process of qualifying and I wanted to measure the discharge current of the battery electronics. Can do this using EV2300? Please advise.

Thank you,

Ramon

    Hi Ramon, welcome to the forums!

    Before I can answer your question, I need to know a few things about what you're trying to do. The EV2300 (and by that extension, the EV2400) don't do any actual interfacing with a battery; they're merely adapters that provide a bridge between the battery fuel gauge and the evaluation software on your PC.

    Do you currently have a TI fuel gauge setup in use, or are you trying to measure a raw battery's capacity? If you're trying to do the latter, you will need to either have your own TI fuel gauge-equipped board, or a TI fuel gauge EVM (evaluation module). Also, what chemistry of battery are you trying to measure (lithium-ion, lithium iron phosphate, lead-acid, etc.), and what configuration is it in (for example, a multi-cell 3S2P pack, using two parallel sets of 3 cells in series)?

    Hopefully I haven't bombarded you with too many questions - the world of fuel gauges can be a rather complex place to navigate at times!

    Regards,

    Jason
