Water；Second sensor 5, second sensor 5 are used to detect the water level for the water being condensed into；Controller 3, controller 3 are used for when condensation
At water water level reach setting water level value when, control will be condensed into water discharge.
It is understood that dehumidification device of the invention is located in battery pack cabinet, to the intracorporal air of battery pack case into
Row dehumidifying, the air into battery pack are used to cool down battery pack, heat up after the cooling battery pack of air, the plate 1 that is then condensed condensation.
Dehumidification device according to the present invention, cold plate 1 make moisture condensation Cheng Shui, and catch basin 2 collects the water being condensed into, control
Device 3 controls the water being condensed into and is discharged in time, not only can be to avoid band on connector of the condensation vapor in battery pack, connection terminal
Carry out adverse effect, and under battery pack box sealing environment, other steam will not be introduced, it can be by the steam of battery pack cabinet
Effectively and reliably remove.
Specifically, as shown in Figure 4 and Figure 6, the signal that second sensor 5 will test the water level for the water being condensed into passes to control
Device 3 processed, when the water level for the water being condensed into reaches setting water level value, the water discharge that the control of controller 3 will be condensed into, when being condensed into
The water level of water when not up to setting water level value, controller 3 controls the water that is condensed into and is not discharged.Setting water level value can be according to electricity
Chi Bao catchment 2 capacity determine.In addition, according to some embodiments of the invention, second sensor 5 is installed in drainpipe 7.
Preferably, as shown in figs. 4 and 6, dehumidification device further includes first sensor 10, and first sensor 10 is for detecting electricity
The water level of 9 outside ponding of pond lodge body；Controller 3 is also used to be condensed into when the water level of battery pack cabinet 9 outside ponding is greater than
When the water level of water, controls the water being condensed into and be not discharged.When the water level of 9 outside ponding of battery pack cabinet is greater than the water for the water being condensed into
When position, the water being condensed into is discharged at this time can make 9 outside ponding of battery pack cabinet invade battery pack cabinet, and it is unfavorable to generate to battery pack
It influences.When the water level of 9 outside ponding of battery pack cabinet is less than or equal to the water level for the water being condensed into, the water being condensed into can be just
Often discharge.In addition, according to some embodiments of the present invention, first sensor 10 is located at the bottom in 9 outside of battery pack cabinet.
