Hardware Setup

Requirements

Jumper Configuration

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 DC2472A battery emulator.

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

    Figure 3 AD-BMSE2E3WLC-48V to Battery Emulator Setup

  • Connect a 5V external power source to the DC2472A battery emulator (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

Cell Voltage Measurement Using DMM

Using a Digital Multimeter (DMM):

Rotate the knob of the DC2472A clockwise to set it to the lowest voltage. Record the measurement for each cell voltage (C1 to C16).

  • Set the DMM to voltage mode

  • Place the probes (+) and (–) between adjacent cells to measure voltage

  • The reading should fall within the specified range to be considered “good”; otherwise, mark it as “bad”

  • Do not remove the supply during measurement

  • Clockwise → lowest voltage (1.3V to 1.7V)

  • Counterclockwise → highest voltage (4.0V to 4.5V)

Test Point Measurement

Using the DMM, measure the following test points (TP) and verify whether each reading is within range. Mark as “Good” if within range; otherwise, mark as “Bad”. Remove the USB supply after completing the test.
