The utility model discloses an initial force applying device for a battery cell, which comprises a clamp used for clamping the battery cell; comprising paired clamping plates and bolts, and the bolts are connected with the paired clamping plates; the fixed pressing plate and the movable pressing plate are used for clamping the battery cell clamp; each clamping plate abuts against the corresponding clamping plate; the fixed pressing plate is provided with a through hole; the force applying mechanism drives the movable pressing plate to move towards or away from the fixed pressing plate; the force measuring element is used for detecting the clamping force of the clamp on the battery cell; and a bolt tightening device which passes through the through hole and tightens the bolt at a set torque. The clamp is clamped by the fixed pressing plate and the movable pressing plate, and initial clamping force tending to be balanced is applied to the battery cell in the clamp by utilizing the force application mechanism; t
