POWER SUPPLY SYSTEM FOR HYBRID VEHICLE AND OPERATION METHOD THEREFOR

摘要

A power supply system for a hybrid vehicle, which is capable of controlling a fuel cell to operate only in sections in which the fuel cell exhibits optimal efficiency and an operating method thereof. The operating method of operating a power supply system for a hybrid vehicle, which includes a battery and a fuel cell, includes a calculation operation of dividing a route from a departure point to a destination marked in three-dimensional (3D) map information into a plurality of sections, and calculating the amount of power of a fuel cell to be used for a vehicle to drive each of the sections; and a fuel cell operation control operation of controlling the fuel cell to be on or off in each of the plurality of sections when the vehicle starts to drive, based on the state-of-charge of battery, the amount of power output from the fuel cell, and the amount of power of the fuel cell for future use.

主权项

1. A power supply system for a hybrid vehicle which includes a battery and a fuel cell, the power supply system comprising:
a calculation unit for dividing a route from a departure point to a destination marked in three-dimensional (3D) map information into a plurality of sections, and calculating an amount of power of the fuel cell for future use for the vehicle to drive each of the plurality of sections; and a fuel cell operation control unit for controlling the fuel cell to be on or off in each of the plurality of sections when the vehicle starts to drive, based on a state-of-charge (SoC) of the battery, an amount of power output from the fuel cell, and the amount of power of the fuel cell for future use.
