Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
A kind of battery pack drier as shown in Figure 1, including the drier that is arranged in battery pack 1, the drier by
Shell 3 and the drier 4 being placed in shell 3 are constituted, and the drier passes through interior cycle air inlet pipe 5 and interior cycle escape pipe 6
It is connected to 1 inside of battery pack, is in communication with the outside by outer circulation air inlet pipe 7 and outer circulation escape pipe 8.It that is can be real
Outer circulation between existing interior cycle, drier and the external world between drier and battery pack 1.
The interior cycle air inlet pipe 5 and interior cycle escape pipe 6 are both provided with the first motor-driven valve 9, the outer circulation air inlet pipe 7
With the second motor-driven valve 10 is respectively provided on outer circulation escape pipe 8, first motor-driven valve, 9 and second motor-driven valve 10 is usually electronic
Ball valve, naturally it is also possible to using other motor-driven valves for playing phase same-action.It is additionally provided with for drying inside the drier
The electric heating element 11 that agent 4 is heated, such as heating wire, electrothermal tube, drier bottom are arranged for detecting drier weight
Gravity sensor 12, be additionally provided with humidity sensor 13 inside the battery pack 1.
In use, humidity sensor 13 is used to detect the humidity in battery pack 1 the utility model, when humidity reaches
When preset value, the first motor-driven valve 9 is opened, and the second motor-driven valve 10 is closed, and the moisture in battery pack 1 is through interior cycle air inlet pipe 5 and interior
Cycle escape pipe 6 recycles in being carried out inside drier, absorbs moisture using the drier 4 in drier, keeps in battery pack 1
Drying.Gravity sensor 12 is used to detect the overall weight of drier, and the moisture absorbed with drier increases, drier
Total weight becomes larger, and when more than preset value, the second motor-driven valve 10 is opened, and the first motor-driven valve 9 is closed, right using electric heating element 11
Drier is heated, and the moisture inside drier carries out outer follow by outer circulation air inlet pipe 7 and outer circulation escape pipe 8 with the external world
Ring, to which moisture to be discharged, it is ensured that the activity of drier.Therefore, the utility model can be effectively to the humidity in battery pack 1
