METHOD FOR CONTROLLING THE BATTERY STATE-OF-CHARGE BALANCING OF A HYBRID VEHICLE, BY CONSIDERING AUXILIARY ELECTRIC FIELD LOAD AND EXTERNAL TEMPERATURE

摘要

PURPOSE: A method for controlling the battery state-of-charge(SOC) balancing of a hybrid vehicle is provided to prevent SOC strategy band value from being entered into a low range.;CONSTITUTION: A current SOC value is monitored. Auxiliary electric field load or external temperature is monitored. An SOC compensation value is calculated according to the auxiliary electric field load or the external temperature. The directionality of the SOC value is determined according to a pre-set hysteresis. According to final SOC value, an SOC strategy band value is set. According to the set SOC strategy band value, the driving point of a vehicle is controlled.;COPYRIGHT KIPO 2011
