They have very promising application prospects in the field of new energy vehicles. When assembling multiple high-kinetic energy storage cell monomers on an energy storage module, workers are required to perform series connection operations on the high-kinetic energy storage cells one by one, which is very troublesome. Not only does it make the series connection work efficiency relatively low, but it also increases the workload of the workers. In addition, when installing the high-kinetic energy storage cell monomers, they need to be fixed one by one, which makes the assembly of the battery module consume more time and energy, and the assembly efficiency is low.

[0006] A movable sealing assembly is installed at the protective sleeve, and the movable sealing assembly can seal the protective sleeve and the matching boss;

[0007] The protective carrier is also equipped with a movable electrical connection mechanism, which is connected to the movable sealing component. The movable electrical connection mechanism is driven by the movable sealing component to move, thereby realizing electrical connection between the battery cells.

[0008] The movable sealing component can protect the movable electrical connection mechanism, and the movable sealing component is also connected to the battery core fixing component.

[0009] Preferably, the movable sealing component is a first sealing baffle, which is inserted into the protective sleeve when sealing the protective sleeve to close the sleeve opening of the protective sleeve.

[0011] Preferably, the movable electrical connection mechanism is a movable insulating carrier plate, the movable insulating carrier plate is inserted into the protective carrier sleeve, and an electrical connection column is fixedly provided on the movable insulating carrier plate.

[0012] Preferably, the battery cell fixing assembly is a battery cell fixing rod, which is movably mounted on the battery cell body, and the battery cell body is fixed by the battery cell fixing rod.

[0013] An energy storage module includes a module carrier box, wherein a battery cell carrier frame is fixedly arranged in the module carrier box;

[0014] The cell body is positioned by the cell carrier frame, and the cell fixing rod cooperates with the cell carrier frame to fix the cell body in the cell carrier frame;

[0015] The module carrier box is equipped with a box closing mechanism, which can be used to close the module carrier box. When the box closing mechanism moves, it can drive the battery cell fixing assembly to move and then drive the movable sealing assembly to move;

[0016] A matching drive assembly is also installed on the module carrier box, and the matching drive assembly drives the box body closing mechanism to move.

[0017] Preferably, the box closing mechanism is a box sealing plate, which is respectively installed on both sides of the module carrier box, and the box sealing plates are closed together to seal the module carrier box.
