Quick Start Guide - Step by Step

  1. 1. Insert the SB201-2 in the SB200.
  2. 2. Set the large red "Number of Cells" jumper in position 2 (or insert amperemeter to measure current).
  3. 3. Insert battery cells in the CELL 1 and CELL 2 sockets - be aware of the polarity.
  4. 4. Connect 12V to the SB200.
  5. 5. Start the AVR Battery Studio SB200 PC software from Atmel Studio or directly.
  6. 6. Connect the USB cable between PC and SB200:
    1. 1. Verify that the USB Status is "Connected" and that the Board is "SB201-2".
    2. 2. Wait for the SB201 to run through calibration (will take up to 30 sec the first time the SB201 is started).
  7. 7. Either press the HWB button on SB200 or start the charger via the PC software to power up SB201. The HWB buttons starts a charge for maximum 1 minute or until you press it again. The charge voltage is set depending on which SB20x that is connected.
  8. 8. Read the following commands:
    1. 1. ManufacturerName ("Atmel")
    2. 2. DeviceName ("SB201-2 - dual cell")
    3. 3. DeviceChemistry ("Lithium-Ion")
    4. 4. ManufacturerData ("App note AVR456")
  9. 9. Test authentication:
    1. 1. Open the authentication dialog by clicking the Battery Pack authentication text or from the menu.
    2. 2. Write "This will fail!!" in the Host Challenge edit box.
    3. 3. Push WRITE, hence READ (reads garbage).
    4. 4. AES Key says "Gandalf says?". Replace with "You cannot pass!".
    5. 5. Write "Authentic batt!!" in the Host Challenge edit box.
    6. 6. Push WRITE, hence READ (read back "Authentic batt!!").
    7. 7. Status should now say "Authentication Accepted".
  10. 10. Try the read commands from SB201. Check the following check boxes:
    1. 1. Voltage
    2. 2. Current
    3. 3. RelativeStateOfCharge
    4. 4. RemainingCapacity
    5. 5. VoltageCell2
    6. 6. VoltageCell1
    7. 7. Push the Update button on the menu to read all the values.
  11. 11. Log data:
    1. 1. Open "Tools→Options" on the menu.
    2. 2. Specify a log file location.
    3. 3. Push the "Auto-generate filename" radio button and push "OK".
    4. 4. Notice how the graphs to the right display the battery current and cell voltages.
    5. 5. Set the load to 100mA by dragging the slider. Notice the graphs.
    6. 6. Increase the current to higher levels and notice how the cell voltage drops.
    7. 7. Leave the load at 500mA, and wait for the battery protection in the SB201 to disable discharging.
    8. 8. Disable the load, and enable the charger at 8400mV, 880mA, for 30 minutes and see how the charging voltage and currents develop.
    9. 9. Disable logging, and inspect the log file.
  12. 12. Explore the application - enjoy.
