I am designing an electric vehicle and choosing the batteries. For this i want to model some inefficiencys into the batteries. I came across the formulae T=C/I^n where
T=battery life
C = capacitence
I= current
n= Peukert's number
would 1.1 for n be ok for lithium ion, it seems to take quite a lot off with large currents, i couldn't find a general number for li-on only that lead acid use 1.2-1.3...
Battery = 100 Ah
Voltage motor = 156 v
cell voltage = 3.3v
average current = 36 Amps
the current was calulated from power requirements at any given time P=IV
