Steady state battery terminal voltage determining method for hybrid electric vehicle, involves calculating steady state battery terminal voltage based on equivalent charge resistance and effective no load charge voltage

摘要

The method involves calculating an equivalent charge resistance based on preset equivalent charge resistance data. An effective no load charge voltage is calculated based on preset effective no load charge voltage data. A steady state battery terminal voltage is calculated at a current charge current, a current battery temperature and a state of charge based on the resistance and the charge voltage.
