  "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 put in a floor and having an interior space ; a gas removal part installed on an upper portion of the interior space and removing gases inside a secondary battery ; an elevator installed on a lower portion of the interior space at an area corresponding to the gas removal part , receiving the secondary battery on a top portion thereof, and moving the secondary battery upward or downward; and a controller controlling the gas removal part and the elevator",
