Embodiment 1

[0028] Such as figure 1 As shown, the lithium battery moisture-proof device for electric vehicles of the present invention includes a lithium battery box 1, an air inlet fan 2 and a drying plate 4; The inside of the lithium battery box 1 is connected; the drying plate 4 is arranged at the air intake end of the air intake fan 2 , and the air is dried through the drying plate 4 and then enters the lithium battery box 1 through the air intake fan 2 .

[0029] During the implementation of this embodiment, an air inlet fan 2 is arranged on the outer wall of the lithium battery box 1, and the air outlet end of the air inlet fan 2 communicates with the inside of the lithium battery box 1, and the drying plate 4 is arranged on the air inlet end of the air inlet fan 2. When the air intake fan 2 is turned on, the air enters the lithium battery box 1 through the air intake fan 2 after being dried by the drying plate 4, which reduces the humidity in the lithium battery box 1 and improves ...

Embodiment 2

[0031] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment also includes a water separation air filter 3; the water separation air filter 3 is arranged between the air inlet fan 2 and the drying tray 4, and the air passes through the drying tray 4 Dry and then flow through the water separation filter 3 and then enter the lithium battery box 1 through the air intake fan 2.

[0032] During the implementation of this embodiment, the water-separating air filter 3 is arranged between the air intake fan 2 and the drying plate 4, and when the air intake fan 2 is turned on, the air passes through the drying plate 4 to dry, and then flows through the water-separating air filter 3 for two Once dried, it enters the lithium battery box 1 through the air intake fan 2, which further improves the safety of the lithium battery in a humid environment.

Embodiment 3

[0034] Such as figure 2 As shown, in this embodiment, on the basis of Embodiment 1, the drying tray 4 includes a drying sheet 41 and a rotating shaft 42; the shape of the drying sheet 41 is circular; the rotating shaft 42 is arranged at the center of the drying sheet 41, And the axis of the rotating shaft 42 is perpendicular to the end surface of the drying sheet 41 ; the drying sheet 41 rotates around the axis of the rotating shaft 42 . This embodiment also includes a drying air duct 5, a drying fan 6 and a heater 7; the air inlet end of the drying fan 6 is connected to the heater 7; the air outlet end of the drying fan 6 is connected to one end of the drying air duct 5, and The other end of the drying air duct 5 faces the end surface of the drying sheet 41 .

[0035] During the implementation of this embodiment, the drying disc 4 includes a drying sheet 41 and a rotating shaft 42. The drying sheet 41 rotates around the axis of the rotating shaft 42. When the drying fan 6 i...

Abstract

The invention discloses a dampproof device of an electric vehicle lithium battery. The dampproof device comprises a lithium battery box, an air-intake fan and a drying disc, wherein the air-intake fan is arranged on the outer wall of the lithium battery box; an air-outlet end of the air-intake fan is communicated with the interior of the lithium battery box; the drying disc is arranged at an air-inlet end of the air-intake fan; and air is dried by the drying disc and then enters the lithium battery box through the air-intake fan. In the dampproof device of the electric vehicle lithium battery disclosed by the invention, as the air is dried by the drying disc and then enters the lithium battery box through the air-intake fan, the humidity in the lithium battery box is reduced, and the safety of a lithium battery in a wet environment is improved.

Description

technical field [0001] The invention relates to an electric vehicle lithium battery, in particular to a moisture-proof device for the electric vehicle lithium battery. Background technique [0002] With the development of industry and the increase of social demand, automobiles play an important role in social progress and economic development. The rapid development of the automobile industry has promoted the development of important industries such as machinery, energy, rubber, and steel, but at the same time it is increasingly facing serious problems of environmental protection and energy shortage.
