METHOD FOR RESETTING STATE OF CHARGE OF BATTERY IN HYBRID VEHICLE
First Claim
1. A method for resetting a state of charge (SOC) of a battery in a hybrid vehicle, the method comprising:
- calculating a first SOC value of the battery after the hybrid vehicle starts;
calculating a second SOC value of the battery using an open circuit voltage (OCV) of the battery;
comparing the second SOC value of the battery with a third SOC value for vehicle start-up, resetting an SOC value of a battery management system (BMS) to the third SOC value when the second SOC value of the battery is smaller than the third SOC value, and resetting the SOC value of the battery management system (BMS) to the second SOC value of the battery when the second SOC value of the battery is larger than the third SOC value;
transmitting a charging request bit to a vehicle controller in order to charge a fourth SOC value of the battery that is not yet reset when the SOC value of the battery management system (BMS) is reset to the third SOC value; and
confirming whether the charging of the fourth SOC value of the battery is completed.

Abstract
A method for resetting an SOC of a battery in a hybrid vehicle includes calculating a first SOC value of the battery after the hybrid vehicle starts. A second SOC value of the battery is calculated using an open circuit voltage (OCV) of the battery. The second SOC value of the battery and a third SOC value for vehicle start-up are compared with each other, an SOC value of a battery management system is reset to the third SOC value when the second SOC value of the battery is smaller than the third SOC value, and the SOC value of the battery management system is reset to the second SOC value of the battery when the second SOC value of the battery is larger than the third SOC value.
