Recommended BDC-settings for a test assembly
Recommended BDC-settings for operation
“fuel cell to battery”:
BDC_1:
UHS_COM_1 > 170V
ILS_MAX_1 >
|
ILS_MIN_2
|
ILS_MIN_1 = -2 (prevention of buckmode)
IHS_MAX_1 >
|
IHS_MIN_2
| (
Recommendation: IHS_MAX_1 > ILS_MAX_1)
IHS_MIN_1 = -2 (prevention of buckmode)
BDC_2:
UHS_COM_2 < UHS_COM_1
|
ILS_MIN_2
|
< ILS_MAX1
ILS_MAX_2 = 2 (prevention of boostmode)
|
IHS_MIN_2
|
< IHS_MAX_1
(
Recommendation: |IHS_MIN_2| > |ILS_MIN_2|)
IHS_MAX_2 = 2 (prevention of boostmode)
HS- and LS-voltage limit regulators have to be set according to the fuel cell and battery specifications.
