TIDA-01040: Battery Dynamic testing

Moe Farag

Part Number: TIDA-01040

Hi all,

Can the TIDA-01040 module be used for dynamic battery testing? For example fast switching between the charging and discharging directions? and if not, what changes could be done to perform dynamic testing?


Much appreciated.

    Moe, hello and thank you for your interest in Texas Instruments reference designs. The design owner is currently out of the office and returning on Monday, December 3rd. your query has been forwarded to him and he should be responding within the next 1-2 business days at the beginning of the week.

    Best Regards,

    Hi John,

    Thank you for your response. I will try to further clarify my questions in order to be more precise.

    The aim of the project is to characterize an 18650 battery.

    • V bus will be connected to a 12V Lead Acid battery.
    • V Batt will be connected to the 18650 battery.
    • TIDA-01040 will be connected to the laptop to write and read the data.

    The questions:

    • Is this board able to run a charging/discharging cycle (Dynamic cycle as shown in the image below)? I mean the transition between the charge and the discharge will be in milliseconds. If not, what changes should be done?
    • What is the max rate of data acquisition & transfer? would 100 HZ be possible?
    • Does the Enable and DIR jumper prevent the dynamic charge and discharge?

    Best regards,

    Moe

    Moe,

    Yes it is possible to dynamically run a charging/discharging cycle with the TIDA-01040 reference design.

    Please see the last slide in the presentation attached showing the measurement results in this condition, the other slides show results of different transient condition results as well as battery impedance measurements.
