Abstract

A condensing system for a battery in a vehicle and a method for condensing moisture in a battery are provided. In one embodiment, the condensing system includes a battery housing, which surrounds a battery interior. At least one battery cell is arranged in the interior. An inlet opening is arranged in the battery housing, for a cooling fluid entering the battery interior. A first outlet opening and a second outlet opening are both arranged in the battery housing. The first outlet opening is in fluid communication with the cooling fluid emerging from the battery interior. A condensing device is arranged in the battery interior and is in fluid communication with the cooling fluid and causes moisture present in the battery interior to condense. The condensed moisture emerges into the environment through the second outlet opening.

First claim

What is claimed is:

1. A condensing system for a battery in a vehicle, the condensing system comprising:
a battery housing, which surrounds a battery interior, in which at least one battery cell is arranged;
at least one first inlet opening, arranged in the battery housing, for a cooling fluid entering the battery interior;
at least one first outlet opening and one second outlet opening, which are both arranged on the battery housing, wherein the first outlet opening is in fluid communication with the cooling fluid emerging from the battery interior; and
a condensing device arranged in the battery interior comprises a porous material, and a cooling line arranged in the battery interior is in physical contact with and passes through the porous material, wherein operation of the condensing system causes moisture present in the battery interior and stemming from the environment to condense, and wherein the condensed moisture emerges into the environment through the second outlet opening.

2. The condensing system according to claim 1 , wherein the porous material comprises a sponge produced from metal.

3. A condensing system for a battery in a vehicle, the condensing system comprising:
a battery housing, which surrounds a battery interior, in which at least one battery cell is arranged;
at least one first inlet opening, arranged in the battery housing, for a cooling fluid entering the battery interior;
at least one first outlet opening and one second outlet opening, which are both arranged on the battery housing, wherein the first outlet opening is in fluid communication with the cooling fluid emerging from the battery interior;
a fluid line extending at least from the first inlet opening to the first outlet opening; and
a condensing device having the fluid line extending through the condensing device, the condensing device arranged in the battery interior and in fluid communication with the cooling fluid in the fluid line and which causes moisture present in the battery interior and stemming from the environment to condense, and wherein the condensed moisture emerges into the environment through the second outlet opening.

4. The condensing system according to claim 3 , including a cooling unit, which is situated in a cooling circuit of the vehicle and is in fluid communication with the condensing device.

5. The condensing system according to claim 4 , wherein the cooling unit is situated outside the battery housing.

6. A method for condensing moisture in a vehicle battery which comprises a battery housing and a battery interior having at least one battery cell arranged in the battery interior, wherein the method comprises the following steps:
providing at least one first inlet opening in the battery housing for a cooling fluid entering the battery interior;
providing at least one first outlet opening and one second outlet opening on the battery housing, wherein the first outlet opening is in fluid communication with the cooling fluid emerging from the battery interior; and
providing a condensing device, which is arranged in the battery interior and is in fluid communication with the cooling fluid and which causes moisture present in the battery interior and stemming from the environment to condense; and
providing a fluid line, which is arranged to extend through the condensing device, the cooling fluid being in fluid communication with the condensing device,
wherein the condensed moisture emerges into the environment through the second outlet opening.
