Friends:
I am using a modified version of the Dankoff load chart (with credit given)
to calculate off-grid loads. There is a section where you enter the
maximum depth of discharge (DOD) for a battery bank. It is my
understanding that the maximum DOD for a lead acid battery bank is 50%.
Is this correct in concept?
Is this a correct value to enter in this cell?
Thanks,
William Miller
PS: I called Ronald Parades at Trojan before this e-mail was sent and here
is what he said: He recommends 20%-30% DOD. Any greater DOD results in
shorter battery life. He noted that in many approaches a design criteria
of multi-day autonomy which is rarely or never used actually calculates
into the final AH result as a virtual decrease in DOD.
