(go directly to the help section of the form, "Lithium-ion : Open Circuit Voltage")
The basic model takes the following form :
OCV(SOC) = Eo + Alpha . (SOC - 0.5) - K / SOC
with:
OCV = |
Open Circuit Voltage |
Eo = |
base voltage |
Alpha = |
slope of the open-circuit line |
SOC = |
state of charge (varies from 0 to 1) |
K = |
SOC correction factor |
Eo, Alpha and K can be set to default values which are technology-sensitive. A limitation is applied when the discharge cut-off voltage or the charge cut-off voltage are reached.
