2.1.1 Items Needed for EVM Setup and Evaluation

  • BQ40Z80 and BQ771807 circuit module
  • EV2400 communications interface adapter or use on-board EV2400 function
  • Cable to connect the EVM to an EV2400 communications interface adapter OR micro-USB cable to connect EVM directly to a computer
  • If using an external EV2400 communications adapter, then this requires a USB cable to connect the communications interface adapter (EV2400 or on the EVM) to the computer
  • Computer setup with Windows® XP, or higher, operating system
  • Access to the Internet to download the Battery Management Studio software setup program
  • One-to-seven battery cells or 1kΩ resistors to configure a cell simulator
  • A DC power supply that can supply 32V and 2A (constant current and constant voltage capability is desirable). Caution: Some power supplies can be damaged by application of external voltages. If using more than 1 power supply, then check the equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to equipment
