The present invention relates to a parallel-type storage battery charge circuit for railway vehicle and a charging system including the same. The parallel-type storage battery charge circuit includes: a power supply unit which supplies a power source; a constant current charge unit which is installed in a first supply line connecting the power supply unit and a storage battery to perform charging of the storage battery with the power source supplied; a direct connection charge unit which is installed in a second supply line connecting the power supply unit and the storage battery such that the direct connection charge unit is connected in parallel to the constant current charge unit, and which performs charging of the storage battery with the power source supplied; and a control unit which is connected to the constant current charge unit and direct connection charge unit to selectively drive the constant current charge unit and direct connection charge unit according to charging capacity of the storage battery. Embodiments of the present invention can improve performance and lifetime of the storage battery by connecting the constant current charge unit and direct connection charge unit in parallel and performing charging of the storage battery, thereby enabling the storage battery to be stabilized through the constant current charge unit, and can reduce charging time by enabling the storage battery to be charged more rapidly through the direct connection charge unit.
