PROBLEM TO BE SOLVED: To provide a gas filling device and a gas filling method for an accumulator capable of efficiently conducting gas filling work to the accumulator. SOLUTION: For filling gas in an accumulator in which the inside of a pressure container is separated to a liquid chamber into/out of which liquid flows, and an expandable gas-sealed gas chamber, gas of a specified mole number preliminarily supplied from a gas supply means is temporarily stored in a constant mole storage container, and stored gas in the constant mole storage container is supplied to the gas chamber in the accumulator to be filled. Thereby, gas filling work to the gas chamber in the accumulator can be conducted in an extremely short time, and a specified pressure can be easily achieved at a specified temperature, accordingly. Especially, by temporarily filling gas of the specified mole number in plural constant mole storage containers, gas can be supplied to gas chambers of plural corresponding accumulators from the constant mole storage containers in order or simultaneously, thereby gas can be filled in the gas chambers of the accumulators more efficiently. |
