Battery test
The following example demonstrates the procedure of conducting a battery test and generating a
battery model with 2281S in the battery test function.
Equipment required
One 2281S DC Power Supply and Battery Simulator
Rechargeable batteries
Wires
Device connections
The battery under test and 2281S can be connected in two-wire sense connection. However, a
four-wire sense connection is recommended because it can cancel out the wire resistance.
Two-wire local sense connection
(on page 2-64).
Test a battery and generate a battery model
To test a battery and generate a battery model using the front panel:
1. Connect the battery to the instrument.
2. Select the battery test function in the startup screen.
3. Press the
MENU
key.
4. Under
Source
, select
(Dis)charge
.
5. Set the target voltage next to
V-Set
. For example, for a lithium-ion battery that works between 3.8
V to 4.2 V, set the target voltage lower than 3.8 V.
6. Set the end current next to
End condition
.
7. Turn
OUTPUT
on in the front panel to discharge the battery.
2281S always absorbs current at its maximum capacity, which is approximately 1 A. This sink
current is not programmable. If the maximum output current of the battery under test is less
than 1 A, you should connect a resistor between the instrument and the battery to prevent the
battery from switching into protection mode or being damaged.
