Embodiment Construction

[0029] figure 1 and figure 2 A drying device 10 according to a first embodiment of the invention is shown by way of example and without limitation in a schematic sectional view, figure 1 is the front view, figure 2 is a side view.

[0030] Here, the drying device 10 is accommodated in a housing 40 . Housing 40 has housing outer wall 12 which separates interior space 34 from surroundings 36 . The housing outer wall 12 substantially surrounds the inner space 34 and seals it off from the environment 36 . According to the invention, the housing 40 is preferably the housing 40 of a battery system 42 , in particular a lithium-ion battery system.

[0031] In this case, the drying device 10 includes a protective chamber 32 which forms a space separated from an interior space 34 . The protective chamber 32 communicates gas-permeably and liquid-tightly with the interior space 34 . exist figure 1 and figure 2 In this first exemplary structural variant shown, the protective ch...

Abstract

The invention relate to a drying device (10). In order to reduce a moisture content of a gas located in an inner chamber (34) of the housing (40), the drying device comprises a desiccant cartridge (18) having a desiccant (20). The drying device (10) comprises a protective chamber (32) which is or can be introduced into the housing (40). The protective chamber (32) is in a liquid-tight manner with respect to the inner chamber (34) and is connected to the internal space (34) in a gas-conducting manner. The desiccant cartridge (18) is arranged in the protective chamber. The invention further relates to a battery system (42) having the drying device (10) and relates to a motor vehicle having the battery system (42).

Description

technical field [0001] The invention relates to a drying device for reducing the humidity of a gas located in the interior of a housing, the drying device having a desiccant cartridge with a desiccant. Furthermore, it relates to a battery system and a motor vehicle having the drying device. Background technique [0002] In order to ensure the safety of battery systems, in particular lithium-ion battery systems, and to optimize the energy and power parameters and service life, the battery cells of the battery system are preferably operated within a defined temperature range. Especially in the case of high power intake and output, it is necessary to avoid heating the battery cells above the specified operating temperature and to dissipate the heat generated by operation. A cooling system is usually used for this purpose. [0003] Furthermore, it may be necessary to heat the cold battery cells to the desired operating temperature. A heating system is also used for this purpo...
