  • 1 × EVAL-ADBMS1816WLC Daughter Board

  • 2 × DC2472A Battery Emulator

  • 1 × MAX32666FTHR Microcontroller

  • 1 × MAX32625PICO Programming Board

  • 2 × isoSPI twisted-pair cables

  • 1 × 10-pin SWD debugger cable

  • 3 × Micro-USB to USB cables

  • 1 × PC/Laptop

  • 2 × Red Alligator-to-Banana Plug Cables (1166-12-0)

  • 2 × Black Alligator-to-Banana Plug Cables (1166-12-0)

  • 12 × Pin Header Shunts (if not yet installed)

  • 1 × Digital Multimeter (DMM)

Jumper Configuration

AD-BMSE2E3WLC-48V Baseboard

From the list of required hardware, select the AD-BMSE2E3WLC-48V Baseboard.

Install the shunt connectors (if not yet installed) and ensure correct positions, as highlighted in red in the figure below.

Important

Header P16 must be configured with the shunt installed between pin 2 and pin 3. This setting configures the board for 48V operation.

Battery Emulator Setup

Note

The DC2472A Battery Emulator Board is used for cell voltage input in this setup.

  • Plug the screw-terminal block into the cell voltage connector of the two DC2472A battery emulators.

  • Connect the first DC2472A battery emulator to the AD-BMSE2E3WLC-48V Baseboard through the cell connector.

    Figure 7 EVAL-ADBMS1816WLC to Battery Emulator Setup

  • Connect a 5V external power source to the DC2472A (J1) using a USB cable. External power supply is recommended for adequate power.

  • Alternatively, power it through a PC using a USB cable.

Power Verification

After powering up:

  • On DC2472A:

    • Blue LED (LED1) should turn ON

Cable and PC Connection

(A). Plug the micro-USB cable to the first DC2472A battery emulator

that is connected to the AD-BMSE2E3WLC-48V baseboard.

(B). Plug the micro-USB cable to the second DC2472A battery emulator

that is connected to the EVAL-ADBMS1816WLC daughterboard.

(C). Plug the micro-USB cable into the MAX32666FTHR microcontroller.

(D). Connect the 2-wire isoSPI cable from P10 of the AD-BMSE2E3WLC-48V baseboard.

(E). Connect the other end of the 2-wire isoSPI cable to P10 of

the EVAL-ADBMS1816WLC daughterboard.

(F). Connect all USB cables to a USB hub (preferred).

Note

If your PC/laptop USB ports can supply ≥1A, you may connect devices directly without a USB hub.

Your setup should look like below:
