GETTING STARTED
Use the following instructions to evaluate the AD-ACEVSE22KWZ-
KIT. While testing, the single-phase input must be connected to
phase A and must not exceed 240V RMS line to neutral voltage or
32A. Place the board inside a protective casing before connecting
to high power.
For setup take the following steps:
1. Connect the LCD companion board to the AD-ACEVSE22KWZ-
SL using the flexible printed circuit (FPC) connector (P9). See
the Figure 5 for more information.
2. Connect the 12V power supply to P15.
3. Upon powering the device, the LCD screen displays a brief
welcome message before switching to the status screen
8).
4. If the LCD does not show the status screen, the firmware on the
board must be rewritten. See
instructions on writing to the board.
For single-phase power test setup, take the following steps:
1. Unplug the 12V supply from P15.
2. Connect a single-phase input to the power, neutral, and ground
ports of P23 (A, N, and E, respectively), as shown in
single-phase wall outlet is suitable.
3. Make sure the jumper between TP110 and TP111 is installed.
4. Connect a single-phase load to the A_OUT, N_OUT, and
E_OUT ports of P13. Use an incandescent lamp (not exceeding
32A) as a load.
Continue to the next section to test the system using RS-485
commands to simulate a vehicle charge session. To test the system
using an EV emulator in place of the RS-485 peripheral, proceed to
the EV Emulator Testing section thereafter.

RS-485 TESTING
This test procedure outlines the steps necessary to evaluate
RS-485 communications, charge control state machine (CCSM)
operation, and metrology in addition to familiarizing users with the
firmware companion scripts available for the AD-ACEVSE22KWZ-
KIT. Single-phase power is not required, but running the tests
without power connected results in zero charge accumulation.
1. Install Python 3.11 on the host PC.
2. Connect the RS-485 port, as described in
cation.
3. The protective casing must be closed before proceeding to step
4.
4. Connect the single-phase input and wait for the LCD to display
the status screen.
5. Run the adi_run_session.py script, as described in
a Charge Session. This simulates a 10-second charge session.
The user will hear the relay switch and power begins flowing
to the load. The LCD displays charge accumulation information
throughout the simulated session.
