Abstract

Disclosed is an electrolyte filling method for a battery (2), the battery (2) comprising a switching valve (21) having an open state and a closed state. A processing apparatus comprises a vacuum evacuation system and an electrolyte filling system which are independent from each other. The electrolyte filling method comprises a vacuum evacuation step followed by an electrolyte filling step. The vacuum evacuation step comprises: connecting a vacuum evacuation pipe of the vacuum evacuation system to the switching valve (21) to bring the switching valve (21) into the open state; controlling a vacuum evacuation device of the vacuum evacuation system to perform vacuum evacuation on the battery (2); and separating the vacuum evacuation pipe from the switching valve (21) after it is confirmed that the vacuum evacuation is completed, so as to bring the switching valve (21) into the closed state. The electrolyte filling step comprises: connecting an electrolyte filling device (1) of the electrolyte filling system to the switching valve (21) to bring the switching valve (21) into the open state; controlling the electrolyte filling system to fill the battery (2) with an electrolyte; and separating an electrolyte filling pipe from the switching valve (21) after it is confirmed that the electrolyte filling is completed, so as to bring the switching valve (21) into the closed state.
