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