Abstract

A battery module comprises a plurality of electrically interconnected battery cells, a module cover, and a battery cell monitoring unit. The battery cells include at least one terminal cover. The battery cell monitoring unit is positioned on an inner face of the at least one terminal cover.

First claim

What is claimed is:

1. A battery module, comprising:
a module body;
a plurality of battery cells that are positioned in the module body and that each include at least one connection terminal;
at least one cell connector that electrically interconnects the plurality of battery cells via the at least one connection terminal of each battery cell; and
a module cover configured to cover the module body in a closed position, and that includes:
at least one terminal cover detachably mounted in the module cover such that, in the closed position of the module cover, the at least one terminal cover covers the at least one cell connector; and
a battery cell monitoring unit detachably mounted in an installation space on an inner face of the at least one terminal cover such that, in the closed position of the module cover, the battery cell monitoring unit contacts at least one of the at least one cell connector and the at least one connection terminal.

2. The battery module according to claim 1 , wherein the battery cell monitoring unit is clipped into the installation space.

3. The battery module according to claim 2 , wherein:
the at least one terminal cover has at least one latching element in a region of the installation space that is configured to mechanically fix the battery cell monitoring unit to the at least one terminal cover; and
the at least one terminal cover having an elasticity that enables the battery cell monitoring unit to clip into and out from the at least one latching element.

4. The battery module according to claim 1 , wherein the battery cell monitoring unit includes at least one spring contact.

5. The battery module according to claim 1 , further comprising a temperature sensor positioned on the inner face of the at least one terminal cover.

6. The battery module according to claim 4 , wherein:
the battery cell monitoring unit includes a printed circuit board; and
the at least one spring contact is positioned on a side of the printed circuit board facing at least one of the at least one cell connector and the at least one connection terminal.

7. The battery module according to claim 1 , wherein the at least one terminal cover is formed from an electrically insulating material.

8. The battery module according to claim 1 , wherein:
the at least one terminal cover includes a tapered material portion; and
the tapered material portion defines a bending line that runs along the tapered material portion and that enables releasing the battery cell monitoring unit from the at least one terminal cover via bending the at least one terminal cover along the bending line.

9. The battery module according to claim 3 , wherein the at least one latching element is at least one encircling latching element.

10. The battery module according to claim 1 , wherein the at least one terminal cover is detachably mounted in the module cover of the battery module by being clipped in the module cover of the battery module.

11. A battery module, comprising:
a module body;
a plurality of battery cells that are positioned in the module body and that each include at least one connection terminal;
at least one cell connector that electrically interconnects the plurality of battery cells via the at least one connection terminal of each battery cell; and
a module cover configured to cover the module body in a closed position, and that includes:
at least one terminal cover detachably mounted in the module cover such that, in the closed position of the module cover, the at least one terminal cover covers the at least one cell connector, wherein the at least one terminal cover includes a tapered material portion that defines a bending line running along the tapered material portion; and
a battery cell monitoring unit positioned on an inner face of the at least one terminal cover such that, in the closed position of the module cover, the battery cell monitoring unit contacts at least one of the at least one cell connector and the at least one connection terminal, wherein the tapered material portion of the at least one terminal cover enables releasing the battery cell monitoring unit from the at least one terminal cover via bending the at least one terminal cover along the bending line.
