2 Test Summary
2.1 Definitions
This procedure details how to configure the BMS035 evaluation board. For the test procedure, the following
naming conventions are followed. Refer to the
VXXX:
External voltage supply name (VADP, VBT, VSBT)
LOADW:
External load name (LOADR, LOADI)
V(TPyyy):
Voltage at internal test point TPyyy. For example, V(TP12) means the voltage at TP12.
V(Jxx):
Voltage at jack terminal Jxx.
V(TP(XXX)):
Voltage at test point “XXX”. For example, V(ACDET) means the voltage at the test point which is
marked as “ACDET”.
V(XXX, YYY):
Voltage across point XXX and YYY.
I(JXX(YYY)):
Current going out from the YYY terminal of jack XX.
Jxx(BBB):
Terminal or pin BBB of jack xx
Jxx ON :
Internal jumper Jxx terminals are shorted
Jxx OFF:
Internal jumper Jxx terminals are open
Jxx (-YY-) ON:
Internal jumper Jxx adjacent terminals marked as “YY” are shorted
Measure: → A,B
Check specified parameters A, B. If measured values are not within specified limits, the unit under test
has failed.
Observe → A,B
Observe if A, B occurs. If they do not occur, the unit under test has failed.
have locations for jumpers, test points, and individual components.
2.2 Equipment
The following list of equipment is required for fully testing the EVM:
1.
Power Supplies
A power supply capable of supplying 26 V at 6 A is required. While this part can handle larger voltage and
current, it is not necessary for this procedure.
2.
Load #1
A 20-V, 6-A system DC electronic load and setting as constant voltage load mode.
3.
Load #2
A Kepco load: BOP36-6M, DC 0 to ±36 V, 0 to ±6 A (or higher), or equivalent.
4.
Meters
Six Fluke 75 multimeters, (equivalent or better) or: Three equivalent voltage meters and three equivalent
current meters.
5.
Computer
A computer with at least one USB port and a USB cable.
6.
EV2400 Communication Kit
7.
Software
