    List of Gauging Parameter Calculator (GPC) tools.

    There are several GPC tools, each with a specific purpose:

    1. gpcCEDV - Determines the Compensated End of Discharge Voltage (CEDV) parameters for your cell. Used with CEDV gauges. Requires a zip archive consisting of: 6 logs in total at 3 temperatures and a config file.
    2. gpcCHEM - Determines the chemID match for your cell. Used with Impedance Track (IT) gauges. Requires a zip archive consisting of: 1 log at room temperature and a config file.
    3. gpcRA0 - Optimizes gauging parameters for IT gauges with respect to increased room temperature and high rate discharge performance. Requires a zip archive consisting of: 1 log of discharge at system-typical high rate, a fresh gg.csv file with only the chemID programmed and a config file.
    4. gpcRB - Optimizes gauging parameters for IT gauges with respect to increased low temperature performance. Requires a zip archive consisting of: 1 log of discharge at room temperature, 1 log of discharge at low temperature, a fresh gg.csv file with only the chemID programmed and a config file.

    How do I upgrade my bqstudio and EV2300/EV2400 toolchain to the latest version?

    Please upgrade bqStudio to the latest 'bqstudiotest' version found here:

    http://www.ti.com/tool/bqstudio

    With your EV2300, please ensure the firmware is more recent than 3.1c.  There is a known communications issue with the 3.1c firmware that will require updating with another EV2300 using the updater, found here: http://e2e.ti.com/cfs-file.ashx/__key/communityserver-discussions-components-files/180/3225.EV2300FWUpdaterUnprogDev.zip


    If you also have an EV2400, please ensure that your EV2400 is running the latest firmware found here:

    The bq34z100-g1 quickstart guide also covers how to set up the latest firmware and software, found here:
