Summary of Changes for USABC Manual Revision 2
(Not including minor editorial and typographical corrections)
DESCRIPTION OF CHANGE
The list of Core Performance Tests is clarified in Figure 1, and the test plan outline
is clarified to note that written direction from the USABC Program Manager is needed
to bypass these tests. The number and type of core tests required is NOT changed.
6, E-2, F-3, F-5
A single ‘Rated Capacity’ value is clearly defined as the basis for measuring depth-
of-discharge (and hence capacity) for all USABC performance tests. The Rated
Capacity is established by the manufacturer based on whatever tradeoffs he chooses to
make for the best balance of power, capacity and life.
Both USABC Test Manager and Program Manager approval are required for all
9, E-3, F-5, I-3
The Discharge Voltage Limit (DVL) for the Peak Power Test is clarified to be a
fixed value established at beginning of life. An alternate equation for calculating Peak
Power Capability is added to account for decreases in open circuit voltage beyond
80% DOD or later in life. Conduct of the Peak Power test itself is NOT changed
except for requiring voltage to stay above the DVL.
13, 15, 40
Discharge Voltage Limit is a default termination condition for FUDS, DST and Life
The DST procedure is modified to eliminate the reduced power criterion for Step 15.
All steps are now treated the same (as in the FUDS test); and the test terminates when
the programmed power cannot be achieved for any step without exceeding a battery
The terminology DSTn is established to indicate the peak power scaling for a DST
test, e.g. DST120 is a test scaled to 120 W/kg.
A vibration test using random vibration is added to Procedure 10. The existing
swept sine wave vibration test is retained unchanged as an alternative.
