Drying device and battery system and motor vehicle having the same

Abstract

The invention relates to a drying device (10) comprising a desiccant cartridge (18) with a desiccant (20) in order to reduce the humidity of the gas located in the interior space (34) of a housing (40) . Here, the drying device (10) has a protective chamber (32) which is placed or can be placed in the housing (40), which is liquid-tight with respect to the inner space (34) and connected gas-conductively with the inner space ( 34), the desiccant box (18) is set in the protection chamber (32). Furthermore, it relates to a battery system ( 42 ) with the drying device ( 10 ) and a motor vehicle with 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...
