Simulate a battery with the 2281S
To simulate a battery with the 2281S using the front panel:
1. Select the battery simulator function in the startup screen.
2. Select
Model
in the soft key area 1.
3. Choose
1.mdl
, since it is the model of a cellphone lithium-ion battery normally seen in the market
with a voltage range of 3.7 V to 4.2 V.
4. Press the
MENU
key.
5. Under
Battery
, select
Settings
.
6. Set
Method
to
Dynamic
. The Voc and SOC of the simulated battery change based on the
charging and discharging, like a real battery.
7. Set
Full V
and
Empty V
as the range of the simulated battery.
8. Return to the battery simulator home screen by pressing
HOME
on the front panel.
9. Select
I-Limit
in the soft key area 2. The current limit cannot be set higher than 6.1 A.
10. Return to the menu.
11. Under
Battery
, select
Settings
.
12. Set
SOC
to 80% and
Voc
to 4.1234 V. The value of Voc must be within the
Empty V
and
Full V
.
The value of
SOC
changes according to the value of
Voc
, and vice versa.
13. Return to the home screen. Set
Capacity
to 200 mAh in soft key area 2. This capacity is set to
accelerate the charging and discharging for better efficiency of the test.
14. Turn
OUTPUT
on in the front panel to start the battery simulation.
To simulate a battery using SCPI commands:
1. To select model 1, send the command:

4. To set the Voc at discharging end (Empty V) to 3.8 V, send the command:
BATT:SIM:VOC:EMPT 3.8
5. To set the current limit to 3 A, send the command:
:BATT:SIM:CURR:LIM 3
6. To set SOC to 80%, send the command:
:BATT:SIM:SOC 80
The Voc value changes accordingly.
7. To set the battery capacity to 200 mAh, send the command:
