  "textContent": "The present invention provides a vacuum hopper precharger configured such that an electrolyte and gases contained in the electrolyte are suctioned by a vacuum hopper, the gases inside the electrolyte are discharged to the outside, and the electrolyte is stored in a vacuum nozzle of the vacuum hopper and then supplied into the secondary battery, thereby reducing defects of the secondary battery and lengthening the life thereof. The present invention comprises: a base frame 20 put in a floor and having an interior space 21; a gas removal part 30 installed on an upper portion of the interior space 21 and removing gases inside a secondary battery 100; an elevator 40 installed on a lower portion of the interior space 21 at an area corresponding to the gas removal part 30, receiving the secondary battery 100 on a top portion thereof, and moving the secondary battery 100 upward or downward; and a controller 50 controlling the gas removal part 30 and the elevator 40.",
