2.1 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 1 A is required. While this part can handle larger voltage and current, it is not necessary for this procedure.
  2. Load #1 (4-Quadrant Supply, Constant Voltage < 4.5 V)
    A 0–20 V/0–5 A, > 30-W system, DC electronic load and setting as constant voltage load mode.
    Or:
    Kepco load: BOP 20–5M, DC 0 to ±20 V, 0 to ±5 A (or higher).
  3. Load #2 – Use with Boost Mode
    PMID to GND load, 10 Ω, 5 W or greater.
  4. Meters
    Six Fluke 75 multimeters, (equivalent or better).
    Or:
    Four equivalent voltage meters and two equivalent current meters. The current meters must be capable of measuring 5 A+ current.
  5. Computer
    A computer with at least one USB port and a USB cable. The bq2589xEVM evaluation software must be properly installed.
  6. USB-to-GPIO Communication Kit (EV2300 USB-Based PC Interface Board)
  7. Software
    Double click the “BatteryManagementStudio-1.3.35_Build2-windows-installer” installation file, follow the installation steps. The software supports the Microsoft®Windows® XP and Windows 7 operating systems.

    8. Install EV2300 Software
