Provided is a battery operating system of a liquefied natural gas carrier (LNGC). The battery operating system of an LNG comprises: a cargo tank for storing liquefied natural gas; a fuel supply device connected to a power grid and for supplying the liquefied natural gas; a re-liquefaction device connected to the power grid and for re-liquefying boil-off gas generated in the cargo tank; a generator connected to the power grid and for supplying power to a consumer; and a battery connected to the power grid, charged based on power generation using fuel, and for supplying the charged power to the consumer. The fuel supply device supplies fuel for the power generation using the fuel to reduce the pressure in a cargo hold, if the pressure value of the cargo hold exceeds a first reference pressure value. The battery can be charged based on the supply of the fuel if the charging rate corresponds to a first chargeable value, and can supply power for operation of the re-liquefaction device if the charging rate corresponds to a first dischargeable value. Therefore, the battery operating system enables efficient management of LNGC energy by linking and operating, in a mutually complex manner, the fuel supply device, re-liquefaction device, and battery system of a ship which have been operated separately and independently.
