METHOD AND DEVICE FOR ADJUSTING BATTERY STATE OF CHARGE (SOC) REQUIREMENTS IN A FUEL CELL VEHICLE USING ROADWAY INFORMATION

A method for correcting a battery state of charge (SOC) of a vehicle includes dividing a roadway segment of a roadway in front of the vehicle into at least two or more segments; obtaining roadway information for each segment of the at least two or more segments of the roadway, determining an expected battery SOC demand value of each segment based on the obtained roadway information, determining whether to correct the expected battery SOC demand value of the each segment based on whether the at least two or more segments have continuous gradients, and based thereon, performing correction of the expected battery SOC demand value.
