Abstract

A high-voltage accumulator battery module includes a first connection component adjacent to a plate-shaped frame component remotely from a heat sink. The first connection component includes at least one of: an inlet first connection unit having a fluid inlet connected to a cooling channel system via an inlet fluid line connecting the fluid inlet to an inlet second connection unit connected to the cooling channel system, and an outlet first connection unit having a fluid outlet connected to the cooling channel system via an outlet fluid line connecting the fluid outlet to an outlet second connection unit connected to the cooling channel system. A second connection component is adjacent to the plate-shaped frame component at the heat sink side, and includes at least one of: the inlet second connection unit, and the outlet second connection unit. A clamping device clamps the first and second connection components against each other.

First claim

What is claimed is:

1. A battery module for a high-voltage accumulator, comprising: at least one electric storage cell;
at least two plate-shaped frame components, which are arranged on end faces and between which the at least one electric storage cell is arranged;
at least one plate-shaped heat sink with at least one cooling channel system, which is connected to the at least one electric storage cell in a thermally conductive manner;

a first connection component arranged adjacent to a plate-shaped frame component remotely from the heat sink, the first connection component comprising at least one of:
an inlet first connection unit having a fluid inlet, the fluid inlet communicatively connected to the cooling channel system via at an inlet fluid line connecting the fluid inlet to an inlet second connection unit that is communicatively connected to the cooling channel system, wherein the inlet fluid line is connected to the inlet first connection unit via at least one seal, and
an outlet first connection unit having a fluid outlet, the fluid outlet communicatively connected to the cooling channel system via at an outlet fluid line connecting the fluid outlet to an outlet second connection unit that is communicatively connected to the cooling channel system, wherein the outlet fluid line is connected to the outlet first connection unit via at least one seal;

a second connection component arranged adjacent to the plate-shaped frame component at a heat sink side so as to connect to the plate-shaped heat sink at an end face of the end faces,
the second connection component comprising at least one of: the inlet second connection unit that communicatively connects the inlet fluid line to the cooling channel system, and the outlet second connection unit that communicatively connects the outlet fluid line to the cooling channel system; and
at least one clamping device, which clamps the first and second connection components against each other.

2. The battery module as claimed in claim 1 , wherein one end of at least one of: the inlet fluid line and the outlet fluid line is connected by integral bonding to the respective second connection unit.

3. The battery module as claimed in claim 1 , wherein the inlet first connection unit and the inlet second connection unit are connected, and the outlet first connection unit and the outlet second connection unit are connected, each via a respective seal, to the respective fluid line.

4. The battery module as claimed in claim 1 , wherein the respective fluid line is guided through a bore arranged on the plate-shaped frame component, wherein an outer diameter of the fluid line is smaller than an inner diameter of the bore.

5. The battery module as claimed in claim 1 , wherein the respective fluid line is formed by a bore in the plate-shaped frame component.

6. The battery module as claimed in claim 1 , wherein the fluid inlet or the fluid outlet is formed as a lateral exit at the respective first connection unit, which is arranged transversely to an entrance of the respective first connection unit which is connectable to the respective fluid line.

7. The battery module as claimed in claim 1 , wherein the first connection component monolithically comprises both the inlet first connection unit and the outlet first connection unit, and the second connection component monolithically comprises both the inlet second connection unit and the outlet second connection unit.

8. The battery module as claimed in claim 1 , wherein the at least two plate-shaped frame components are configured as module holders, by which the battery module is securable to a housing of the high-voltage accumulator, the fastening of the battery module to the housing being done at least partly by the clamping device.

9. The battery module as claimed in claim 1 , wherein the battery module is configured for the high-voltage accumulator of an electrically drivable motor vehicle.

10. A high-voltage accumulator, comprising:
at least one battery module for the high-voltage accumulator, the battery module comprising:

at least one electric storage cell:
at least two plate-shaped frame components, which are arranged on end faces and between which the at least one electric storage cell is arranged:
at least one plate-shaped heat sink with at least one cooling channel system;
which is connected to the at least one electric storage cell in a thermally conductive manner:

a first connection component arranged adjacent to a plate-shaped frame component remotely from the heat sink, the first connection component comprising at least one of:
an inlet first connection unit having a fluid inlet, the fluid inlet communicatively connected to the cooling channel system via an inlet fluid line connecting the fluid inlet to an inlet second connection unit that is communicatively connected to the cooling channel system, wherein the inlet fluid line is connected to the inlet first connection unit via at least one seal;
and
an outlet first connection unit having a fluid outlet, the fluid outlet communicatively connected to the cooling channel system via an outlet fluid line connecting the fluid outlet to an outlet second connection unit communicatively connected to the cooling channel system, wherein the outlet fluid line is connected to the outlet first connection unit via at least one seal;
a second connection component arranged adjacent to the respective plate shaped frame component at a heat sink side so as to connect to the plate-shaped heat sink at an end face of the end faces, the second connection component comprising at least one of: the
inlet second connection unit that communicatively connects the inlet fluid line to the cooling channel system, and the outlet second connection unit that communicatively connects the outlet fluid line to the cooling channel system; and
at least one clamping device, which clamps the first and second connection components against each other.

11. The high-voltage accumulator according to claim 10 , wherein the high-voltage accumulator is configured for an electrically drivable motor vehicle.
