Abstract

A carrier board element is provided for the cell connectors of a battery having a plurality of battery cells. The carrier board element has a plurality of cell holders uniformly spaced apart from each other. At least one locking element for the locking in of a cell connector is associated with each of the cell holders. The locking element is arranged on the carrier board element. A plurality of cell connectors can be captively locked in one over the other at the locking elements.

First claim

What is claimed is:

1. A carrier board element for cell connectors of a battery having a plurality of battery cells, comprising:
a plurality of cell holders spaced uniformly apart from one another, each of said cell holders being assigned at least one locking element for a cell connector to be locked in, wherein
the at least one locking element of each cell holder is arranged on the carrier board element,
a plurality of cell connectors are captively lockable-in one above another on the locking elements, and
a locking element has a central axis, around which there are arranged at least two snap-in hooks locking radially with respect to the central axis.

2. The carrier board element as claimed in claim 1 , wherein
there are three or four snap-in hooks.

3. A carrier board element for cell connectors of a battery having a plurality of battery cells, comprising:
a plurality of cell holders spaced uniformly apart from one another, each of said cell holders being assigned at least one locking element for a cell connector to be locked in, wherein
the at least one locking element of each cell holder is arranged on the carrier board element,
a plurality of cell connectors are captively lockable-in one above another on the locking elements, and
a locking element has a central axis and a hot-pressed pin extending along thereon.

4. The carrier board element as claimed in claim 1 , further comprising:
at least two cell connector rows each with a plurality of uniformly spaced cell holders.

5. The carrier board element as claimed in claim 4 , wherein
the cell connector rows are arranged so as to be offset from one another.

6. The carrier board element as claimed in claim 5 , wherein
the offset is a spacing of two adjacent cell holders of a row.

7. A carrier board, comprising:
at least two carrier board elements as claimed in claim 1 , wherein
adjacent carrier board elements are fixable to one another by a tongue-and-groove connection and by the cell connectors to be locked in on the locking elements.

8. A carrier board, comprising:
at least two carrier board elements as claimed in claim 1 , wherein
adjacent carrier board elements are fixable to one another by a plastic welded connection.

9. The carrier board as claimed in claim 7 , further comprising:
a front and a rear current tap-off element, wherein
each of the current tap-off elements is connected to one of the carrier board elements.

10. A battery, comprising:
a plurality of battery cells; and
a carrier board as claimed in claim 7 , in which the number of the carrier board elements is matched to the number of battery cells, wherein more than one cell connector is locked-in on at least one of the locking elements.

11. The battery as claimed in claim 10 , wherein
to connect at least two battery cells, a second cell connector is locked-in on a locking element above a first cell connector which connects more than two battery cells.

12. The battery as claimed in claim 10 , wherein
to connect at least two battery cells, a second cell connector is arranged between two first cell connectors, wherein the second cell connector has an overlap region with each of the first cell connectors, on which both cell connectors are locked-in by a locking element.

13. The battery as claimed in claim 11 , wherein a third cell connector is locked-in above the second cell connector.

14. The battery as claimed in claim 10 , wherein
a socket or a pin bar for a plug of a battery control system is arranged above the cell connectors.

15. The battery as claimed in claim 14 , wherein
the socket or the pin bar is a BMS socket or a BMS pin bar.
