BESS Project 4MW/6MWh，discharge time is 1.5h

daxia

but the discription is The discharge and charge rate should be less than or equal to 1C，it is more than 1 hour，is can equal to 1.5h?
280A1h=280Ah
280A166.4V1h=46592VA1h
=46.592kW*1h
=46.592kWh
from these values,use 1h not 1.5h
i donot know the hour how to correspond？

When we say that the charge and discharge rate of a battery cell is 0.5C/1C, it means that the battery cell can meet the charge and discharge rate of no more than 0.5C/1C during the charge and discharge process.
Battery cell products usually have two specifications: 0.5C and 1C. The actual requirement of 4MW/6MWh is 0.66C. Obviously, the 1C battery cell can meet the requirement, but the 0.5C one can not. Therefore, the 1C battery cell should be selected.
