[0002] A battery pack is usually composed of multiple battery cells and is used to store electrical energy for future use. These batteries can store electrical energy by charging, and then release the electrical energy to supply equipment or systems when needed. Battery packs are widely used in solar photovoltaic systems, wind power generation systems and other fields;

[0003] Photovoltaic power generation is mostly deployed in outdoor environments. In order to avoid the battery performance degradation of the battery pack in a low temperature environment and slow down the battery capacity loss, a heat preservation mechanism is set outside the battery pack to keep the battery pack warm. At present, the heat preservation of the battery pack is mostly directly bonded to the inner wall of the battery box to improve the heat preservation effect of the battery pack. Although this method can keep the battery pack warm, it still has the following defects in actual use:

[0004] During the use of batteries, they will generate heat. The thermal insulation cotton is located inside the battery shell, which will reduce the heat dissipation effect of the battery. Especially in hot weather, the battery is prone to overheating, which will cause the battery to swell, the shell to deform and crack, etc., thus causing safety hazards and reducing safety.

[0005] Therefore, the present application proposes a photovoltaic power generation outdoor heat preservation type battery pack. Utility Model Content

It should be noted that: the photovoltaic panel 21 and the battery pack body 12 are electrically connected through an inverter. The prior art belongs to the well-known technical scope of those skilled in the art and will not be described in detail here. A cover plate 13 for blocking the open end of the mounting groove 11 is fixedly mounted on the top of the battery box 1 by screws to achieve the effect of blocking the open end of the mounting groove 11; a receiving groove 14 is provided at the bottom of the battery box 1 and is located on the outside of the mounting groove 11, and a bottom plate 3 for blocking the open end of the receiving groove 14 is fixedly mounted on the bottom of the battery box 1 by screws, and a cover plate 13 that can be inserted into the receiving groove 14 is fixedly mounted on the bottom plate 3 The partition 31 in the receiving groove 14, when the bottom plate 3 blocks the open end of the receiving groove 14, the partition 31 is used to separate the receiving groove 14 into a cavity 1 141 and a cavity 2 142 which are independent of each other, and the cavity 1 141 and the cavity 2 142 are both filled with thermal insulation cotton 15. Through the design of the thermal insulation cotton 15, the cavity 1 141 and the cavity 2 142 are both filled with thermal insulation cotton 15, thereby achieving a thermal insulation effect in the installation groove 11, and achieving a thermal insulation effect on the battery pack body 12 in the installation groove 11. Effectively avoid the situation where the battery performance of the battery pack body 12 is degraded in a low temperature environment; a plurality of vent holes 111 connected to cavity 1 141 are provided on the inner wall on one side of the installation groove 11, and a plurality of vent holes 112 connected to cavity 2 142 are provided on the inner wall on the other side; an air inlet 32 ​​connected to cavity 1 141 is provided on the bottom plate 3, and a negative pressure component 4 acting on cavity 2 142 is installed on the bottom plate 3, which is used to draw the air in cavity 2 142 outward.

[0035] By setting the bottom plate 3 to be fixedly installed at the bottom of the battery box 1 by screws and sealing the open end of the accommodating groove 14, when it is not in a low temperature weather environment, the bottom plate 3 can be disassembled, so that the thermal insulation cotton 15 can be pulled out and disassembled from the accommodating groove 14, and then fixed between the bottom plate 3 and the battery box 1, which is beneficial to the heat dissipation of the battery pack body 12.

Sealing grooves are provided at the bottom of the box 1 and on the outside of the accommodating groove 14. Rubber pad 113 and rubber pad 2 114 are fixed in the two sealing grooves respectively. When the cover plate 13 seals the open end of the installation groove 11, the cover plate 13 and rubber pad 113 form a conflict. When the bottom plate 3 seals the open end of the accommodating groove 14, the bottom plate 3 and rubber pad 2 114 form a conflict, thereby increasing the fit between the cover plate 13 and the bottom plate 3 and the battery box 1, thereby increasing the sealing between the cover plate 13 and the bottom plate 3 and the battery box 1.

Through the design of the power socket 17, when in use, the power plug of the external appliance is connected to the power socket 17 to power the external appliance, which is convenient for powering the external appliance. A blocking member 7 for blocking or unblocking the groove 16 is installed on the battery box 1. Through the design of the blocking member 7, when not in use, the blocking member 7 can be used to block the groove 16, thereby achieving a blocking protection effect on the power socket 17.

[0045] In this embodiment, the blocking member 7 includes a horizontal plate 71 fixedly mounted on the outer wall of the battery box 1 and located above the groove 16.
