Abstract
In a power control device for a vehicle in which an electric motor for driving the vehicle to travel is supplied with power from a battery mounted on the vehicle and a fuel cell, a control unit sets a target charging rate (SOCt) of the battery in such a manner that the target charging rate decreases as a remaining fuel amount (Qf) of the fuel cell decreases after the power generation of the fuel cell is started during high-output/high-speed travelling and controls a power generation output (Pf) of the fuel cell based on a difference between the target charging rate (SOCt) and a current charging rate (SOC).
