VEHICLE INCLUDING FUEL CELL, BATTERY-CHARGING METHOD FOR THE VEHICLE, AND RECORDING MEDIUM HAVING RECORDED THEREIN PROGRAM FOR EXECUTING THE METHOD

A vehicle includes a boost converter configured to bypass or to convert a stack voltage and output the bypassed or converted stack voltage as a first voltage in response to a first control signal, a first switching unit configured to be switched in response to a first switching signal to form a main path to supply the first voltage to a battery, a buck converter configured to convert and output a level of the first voltage to the battery as a second voltage in response to a second control signal, a second switching unit configured to be switched in response to a second switching signal to form a bypass path to supply the second voltage to the battery, and a controller configured to inspect a level of voltage charged in the battery and generate the first and second control signals and the first and second switching signals based thereon.
