Abstract

A drying device includes a desiccant cartridge having a desiccant to reduce a moisture content of a gas located in an inner chamber of a housing. The drying device has a protective chamber which is configured to be introduced into the housing in a liquid-tight manner with respect to the inner chamber and which is connected to the internal space in a gas-conducting manner. The desiccant cartridge is arranged in the protective chamber. A battery system includes the drying device and a motor vehicle includes the battery system.

First claim

The invention claimed is:

1. A battery system, comprising:
a housing and an internal space substantially enclosed by the housing; and
a drying device introduced into the housing, the drying device including:
a desiccant cartridge comprising a desiccant; and
a wall at least in part defining a protective chamber arranged in the housing,
wherein the protective chamber (i) is liquid-tight in relation to the internal space and (ii) has a first gas-conducting connection to the internal space, and
wherein the desiccant cartridge is arranged in the protective chamber.

2. A motor vehicle, comprising:
a propulsion system; and
at least one battery system connected to the propulsion system of the motor vehicle, the battery system including:
a housing and an internal space substantially enclosed by the housing; and
a drying device introduced into the housing, the drying device including:
a desiccant cartridge comprising a desiccant; and
a wall at least in part defining a protective chamber arranged in the housing,
wherein the protective chamber (i) is liquid-tight in relation to the internal space and (ii) has a first gas-conducting connection to the internal space, and
wherein the desiccant cartridge is arranged in the protective chamber.

3. The battery system as claimed in claim 1 , wherein the first gas-conducting connection is configured as a first pressure-equalizing element.

4. The battery system as claimed in claim 3 , wherein the wall is configured as a protective cover arranged in the housing on a housing outer wall of the housing, the protective cover and the housing outer wall forming the protective chamber, and wherein the first pressure-equalizing element is arranged in the protective cover.

5. The battery system as claimed in claim 3 , wherein the wall is configured as a protective sleeve that forms the protective chamber, the protective sleeve configured to be inserted into the housing through a housing aperture defined by a housing outer wall of the housing, and wherein the first pressure-equalizing element is arranged in the protective sleeve.

6. The battery system as claimed in claim 5 , wherein the protective sleeve has an external thread and is configured to be screwed into the housing.

7. The battery system as claimed in claim 1 , wherein the drying device comprises a sensor unit configured to detect an absorption capacity of the desiccant.

8. The battery system as claimed in claim 7 , wherein the sensor unit comprises a display having an appearance that varies as a function of the absorption capacity of the desiccant.

9. The battery system as claimed in claim 7 , wherein the sensor unit comprises an electronic sensor configured to be connected to an electronic management system.

10. The battery system as claimed in claim 1 , wherein the desiccant cartridge has a second gas-conducting connection to surroundings outside of the housing, the gas configured to follow one or more of a first flow path from the internal space, through the protective chamber, and to the surroundings and a second flow path from the surroundings, through the protective chamber, and to the internal space.

11. The battery system as claimed in claim 10 , wherein the second gas-conducting connection is configured as a second pressure-equalizing element.

12. The motor vehicle as claimed in claim 2 , wherein the first gas-conducting connection is configured as a first pressure-equalizing element.

13. The motor vehicle as claimed in claim 12 , wherein the wall is configured as a protective cover arranged in the housing on a housing outer wall of the housing, the protective cover and the housing outer wall forming the protective chamber, and wherein the first pressure-equalizing element is arranged in the protective cover.

14. The motor vehicle as claimed in claim 12 , wherein the wall is configured as a protective sleeve that forms the protective chamber, the protective sleeve configured to be inserted into the housing through a housing aperture defined by a housing outer wall of the housing, and wherein the first pressure-equalizing element is arranged in the protective sleeve.

15. The motor vehicle as claimed in claim 14 , wherein the protective sleeve has an external thread and is configured to be screwed into the housing.

16. The motor vehicle as claimed in claim 2 , wherein the drying device comprises a sensor unit configured to detect an absorption capacity of the desiccant.

17. The motor vehicle as claimed in claim 16 , wherein the sensor unit comprises a display having an appearance that varies as a function of the absorption capacity of the desiccant.

18. The motor vehicle as claimed in claim 16 , wherein the sensor unit comprises an electronic sensor configured to be connected to an electronic management system.
