Testing a single cell at a time is practical when a suspect cell
has been identified by either voltage, specific gravity or internal
resistance measurement. The single cell test approach avoids the
over-testing of remaining cells and is often used in the telephone
and nuclear industries.
The
Perfect Match for the Cellcorder
Designed
for 2 volt cells, the SCT is the perfect complement to the Cellcorder.
After the Cellcorder identifies a potentially bad cell, the SCT
assesses absolute battery capacity using a load test compliant with
IEEE. Automatic operation and safety circuits let you program the
unit and start the test.
System
Description
The
cell under test may be programmed for a discharge current up to
650 amps (SCT 600) or 1200 amps (SCT 1200) down to an end voltage
of 1.75 volts. After cell discharge is complete, the programmable
charger initiates the charge cycle. The maximum charger current
is 120 amps. The charger is internally current limited to 150 amps.
The
SCT can be used with the cell on-line. The SCT package includes
the discharge/charge unit, load cables, and Windows software. An
optional laptop computer is available.
Advantages
and Features
- Performs
a programmable constant current or profile discharge test.
- 650
amp internal resistive load bank (SCT 600)
or 1200 amp internal resistive load bank (SCT 1200).
- A
1.80 to 2.60 volt, 0 to 120 amp, programmable charger. Automatically
recharges the cell after the test.
- Stores
all test data for future report generation.
- USB
interface and communication circuitry interfaces to the computer.
- Safety
circuits prevent damage to the cell under test.
A
Report Generator is Included
The
Report Generator included with the SCT software reads test data
files generated by the SCT program and creates reports. Using the
Report Generator, you can customize your reports and include graphs
that show detailed test data. After you create the report, save
it in an archive format to protect it against changes and ensure
information integrity, then forward it to clients who can view it
with the stand-alone viewer.
