Simulating A Battery - Tektronix Keithley 2281 Series Reference Manual

Model 2281S-20-6 DC Power Supply and Battery Simulator Reference Manual
You can choose a battery model to simulate the battery in your lab. For details of other settings, refer
to Settings menu
There are two methods of simulation:
Static. During static simulation, the open voltage and SOC stay the same.
Dynamic. During dynamic simulation, the open voltage and SOC change with charging and
discharging.

Simulating a battery

To simulate a battery using the front panel:
1. Select the battery simulator function on the startup screen.
2. Select Model in soft key area 1, and then select a model.
3. Press the MENU key.
4. Under Battery, select Settings.
5. Set Method to Dynamic. Thus the Voc and SOC of the simulated battery will change based on
charging and discharging, like a real battery.
6. Set Full V and Empty V as the range for the simulated battery.
7. Return to the battery simulator home screen by pressing HOME on the front panel.
8. Select I-Limit in soft key area 2. The current limit cannot be set higher than 6.1 A.
9. Return to the menu.
10. Under Battery, select Settings.
11. Set SOC. The value of Voc changes based on the value of SOC.
12. Return to the home screen and set Capacity.
13. Turn OUTPUT on in the front panel to start the battery simulation.
To simulate a model 1 battery using SCPI commands:
:BATT:MOD:RCL 1
To set the simulation mode to Dynamic, send the command:
:BATT:SIM:METH DY
To set the V-full value to 4.2 V, send the command:
:BATT:SIM:VOC:FULL 4.2
To set the V-empty value to 3.8 V, send the command:
BATT:SIM:VOC:EMPT 3.8
To set the current limit to 3 A, send the command:
:BATT:SIM:CURR:LIM 3
