6. Set the end current to 10 mA next to
End condition
.
7. Return to the battery test home screen by pressing
HOME
on the front panel.
8. Select
Measure AH
in soft key area 2.
9. Set the state to
On
. The charging starts with measurement results (voltage/current/Amp-Hour)
displayed on the screen.
You can view the charging process by selecting
Graph
or
Data Sheet
in soft key area 2 when the
charging is in progress.
To charge a battery using SCPI commands:
:BATT:TEST:SENS:AH:VFUL V2
:BATT:TEST:SENS:AH:ILIM A2
:BATT:TEST:SENS:AH:ESRI S30
These commands:
Set V-Full to V2
Set the maximum charging limit to A2.
Set the sampling interval to 30 s.
To start the charging and measurement, send the command:
:BATT:TEST:SENS:AH:EXEC STAR
The values V2 and A2 are to be provided by the battery manufacturer. Improper settings might
damage the battery.
Generating and editing a battery model
Only a complete charging test can be the basis for generating a battery model.
A complete charging means the battery is charged from 0 percent capacity to 100 percent capacity.
An incomplete charging may not be able to provide the basis covering battery performance in all
situations for generating a battery model.
Only the data from charging can be used for generating a battery model because the discharging
current cannot be set.
When charging is finished, you can choose to generate a battery model after setting the voltage
range for the battery model. As you can see from the following figure, the range should be well within
the V-empty and V-full set values during charging.
