Description

Battery pack module of energy storage machine

Technical Field

The utility model relates to a battery package, concretely relates to battery package module of energy storage machine.

Background

The household energy storage equipment comprises key components such as a lithium ion battery, an energy storage inverter, a control system and the like, the energy storage scale is 5-10kWh, the household photovoltaic system can be matched to meet daily power consumption requirements of a household, peak clipping and valley filling and demand power charge saving are realized, and for European and American countries, the energy storage system is usually used by American families to store electric energy in a low power price period and use the electric energy in a high power price period due to large power consumption and large price difference between peak and valley power charges, so that the purpose of saving the power charge is achieved. In addition, in remote areas and areas with high natural disasters such as earthquakes and hurricanes, the household energy storage system is used as an emergency power supply, so that inconvenience caused by frequent power failure due to disasters or other reasons is avoided. The energy storage machine is used for storing electric energy, and supplies power to a load through a built-in grid-connected and off-grid energy storage inverter for the electric energy generated by photovoltaic when the load is illuminated, and charges a built-in storage battery pack; when no light is emitted, the built-in storage battery is matched with a power grid to supply power to the alternating current load. The battery pack of the conventional energy storage machine is unreasonable in structural design, poor in sealing performance between the box body and the cover plate and poor in waterproof performance, and the battery pack also has the defects of complex structure, unreliable performance and inconvenient and quick assembly.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance is reliable, the assembly is convenient, the battery package module of energy storage machine that waterproof performance is good.

In order to achieve the above object, the utility model discloses a battery package module of energy storage machine, its characterized in that: including the box, set up apron on the box, set up the battery pack in the box, set up in the box and be connected BMS circuit board, the setting just the socket of being connected with the battery pack electricity on the apron, the box on be provided with around the turn-ups of bending along outside the battery pack, the apron in be provided with and bend turn-ups matched with sealing washer, the sealing washer conflict on the turn-ups of bending, and constitute the sealed cooperation of apron with the box, and be provided with a plurality of screws on the apron, a plurality of screws pass apron, sealing washer in proper order and connect on the turn-ups of bending.

The beneficial effect of above-mentioned structure is: the box body is provided with a bending flanging, and the bending flanging is matched with a sealing ring in the cover plate, so that the sealing performance of the box body and the cover plate can be improved, the waterproof performance of the battery pack module can be improved, and the battery cell assembly adopts a modular design, so that the modular assembly of the battery cell assembly and the box body is facilitated. Therefore, the battery pack module has the advantages of simple structure, stable and reliable performance, convenience in assembly and good waterproof performance.

Particularly, a heat sink is provided on one side of the BMS wiring board. The radiator can play the radiating role, is favorable to the heat dissipation of BMS circuit board to can improve the operational reliability of this battery package module.

Particularly, a pressure relief hole is formed in one side of the box body, and an explosion-proof pressure relief valve is arranged in the pressure relief hole. The explosion-proof pressure relief valve can play the function of explosion-proof pressure relief to can improve the security performance of this battery package module.
