2.3 Equipment

This section includes a list of supplies required to perform tests on this EVM.

  1. Power Supplies: Power Supply #1 (PS #1): A power supply capable of supplying 5 V at 3.5 A is required. While this part can handle larger voltage and current, the part is not necessary for this procedure.
  2. Load #1 for simulating a battery: 4-Quadrant Supply, Constant Voltage < 4.5 V) "Kepco" Load, BOP, 20-5M, DC 0 to ±20 V, 0 to ±5 A (or higher)

    Alternative Option: A 0–20V/0–3.5 A, > 30-W DC electronic load set in a constant voltage loading mode

  3. Load #2 for simulating a load at SYS or load at VBUS in reverse/OTG mode: Electronic or Resistive Load capable sinking up to 5-A from up to 9 V (or higher)
  4. Meters: 4x "Fluke 75" multi-meters, (equivalent or better).

    Alternative Option: (2x) equivalent voltage meters and (2x) equivalent 5-A or higher rated current meters.
  5. Computer: A Windows 10 based computer with at least one USB port and a USB cable. Must have the latest version of Battery Management Studio installed.
  6. USB-TO-GPIO Communication Kit: EV2400 USB-based PC interface board.
  7. Software: BQStudio software with latest .bqz file for BQ25638x provided by Texas Instruments. Download and install bqStudio from https://www.ti.com/tool/BQSTUDIO.
