PURPOSE: To provide an electrolytic liquid filling method and electrolytic liquid filling equipment capable of deeply, quickly, accurately impregnating an electrolytic liquid into an electrolytic liquid impregnating material. CONSTITUTION: Electrolytic liquid filling equipment comprises an electrolytic liquid storage tank 1 for storing an electrolytic liquid L, a microcylinder 2 for supplying the electrolytic liquid L in the electrolytic liquid storage tank 1 to a rechargeable battery 3, a sealing device 4 for making the inside of the rechargeable battery 3 airtight, a vacuum pump 5 for making the inside of the rechargeable battery 3 in a vacuum state, and a needle valve 6 for returning the inside of the rechargeable battery 3 to atmospheric pressure. By reducing the pressure in the rechargeable battery 3, filling the specified amount of electrolytic liquid into the rechargeable battery 3, then returning the inside to atmospheric pressure, the electrolytic liquid is absorbed into an electrode plate 3b of the rechargeable battery 3. |
