Abstract

The invention belongs to the technical field of batteries, and discloses a battery pack and an assembly method thereof, the battery pack comprises a plurality of unit groups and a lower box body, each unit group comprises a cell stack body and two insulation mounting plates respectively connected to two ends of the cell stack body; a groove is formed in the lower box body, a plurality of cross beams which are arranged in parallel at intervals are arranged in the groove, the plurality of cross beams divide the groove into a plurality of battery cell mounting grooves, the unit groups are mounted in the battery cell mounting grooves, and the battery cell stacking body has pre-tightening force. And the two insulating mounting plates at the two ends of the battery cell stacking body are respectively clamped on the two cross beams at the two ends of the battery cell mounting groove. According to the battery pack and the assembly method thereof provided by the invention, the available space of the battery cells is increased, the energy density is improved, the cost is reduced, and the assembly efficiency of the battery pack is also improved.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a battery pack and an assembling method thereof. Background technique [0002] At present, a battery pack is formed by assembling a plurality of battery modules into a box. The battery cell stacks of the existing battery modules are grouped through the cooperation of straps and end plates, and the battery modules are fixed to the inner box by bolts. On the beam, there are many straps, bolts and other components, which take up a lot of space, resulting in low energy density of the battery pack, small available space for the cell, high cost, and complicated manufacturing process. [0003] Therefore, there is an urgent need for a battery pack and an assembling method thereof to solve the above technical problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a battery pack and an assembling method thereof, which are used to sol...
