Embodiment Construction

[0024] The figure shows a battery 1 which is formed from a plurality of electrically conductively connected battery cells. The battery 1 is located in a substantially closed casing 10 . In this case, the battery 1 is mounted on a cooling system 110 which, for optimal cooling, is equipped with cooling medium lines 111 for the flow of cooling medium. Connected to the housing inlet 11 is an inlet valve 12 which is in fluid communication with the drying device 50 . Arranged in a bypass with respect to the intake valve 12 is a pressure compensation valve 13 which is thus likewise connected to the housing interior. On the opposite side, the housing 10 has a housing outlet 14 on which a vent valve 15 is arranged. A line 16 with an opening 17 connected to the housing output is connected to the vent valve 15 . In addition to battery 1 and cooling system 110 , gas 20 is present in the interior of housing 10 . The gas, for example external air, is received by the drying device 50 and...

Abstract

The invention relates to a method and a device for decreasing moisture in a gas (20) in a housing interior (10), in particular in a battery housing interior, a gas (30) having a lower proportion of water vapour than the gas (20) in the housing interior (10) being generated by means of a drying device (50) and introduced into the housing interior (10), and a gas (20) being discharged out of the housing interior such that the housing interior (10) is at least partially filled with the gas (30) having a lower proportion of water vapour.

Description

technical field [0001] The invention relates to a method for reducing the humidity of a gas in a housing interior, in particular a battery housing, and to a method for reducing the humidity in a housing interior of an energy storage system. humidity equipment. [0002] Preferably, the method and the device are used for reducing the humidity in the interior of a housing in which battery cells or batteries are arranged. The battery cells and the batteries assembled from the battery cells form, in a known manner, one or more accumulators, which can be charged and discharged. A battery cell is here an individual galvanic cell which, depending on the combination of materials of the electrodes of the cell, provides a characteristic voltage. The battery cells can be connected in series or in parallel with each other to form a battery. Background technique [0003] Recently, lithium-ion batteries in particular are more widely used in mobile phones, notebook computers and other po...
