Abstract

The invention relates to a HV-battery, in particular a traction battery for a vehicle, having a plurality of cell modules which each comprise a plurality of cells, wherein each cell module is assigned a controller for cell monitoring and/or for cell balancing, wherein the controllers are connected to a battery management control device for communication or open-loop control and/or closed loop control purposes, wherein the HV-battery is of modular construction by configuring the cell modules as plug-in modules that are detachably mountable or can be mounted to a printed circuit board.

First claim

The invention claimed is:

1. A HV-battery, comprising:
a printed circuit board;
a plurality of cell modules configured as plug-in modules for detachable securement to the printed circuit board so as to establish a modular configuration of the NV-battery, each of the cell modules including plural cells;
a plurality of controls, operably connected to the cell modules in one-to-one correspondence, for cell monitoring or cell balancing;
a battery management control unit, connected to the plurality of controls, for communication or open-loop or closed-loop control purposes;
a frame for arrangement of the management control unit,
wherein one member selected from the group consisting of the cell modules and the printed circuit board has projections or latching elements for engagement in recesses of the other member of the group,
wherein the cell modules are arranged side-by-side in a longitudinal direction and have a joint upper surface and a joint lower surface spaced from one another in a transverse direction, said joint lower surface of the cell modules being fully covered by the printed circuit board, and said joint upper surface of the cell modules being fully covered by the frame.

2. The HV-battery of claim 1 , configured for use as a traction battery of a vehicle.

3. The HV-battery of claim 1 , further comprising an outlet box or splitting box in the form of a plug-in module which includes at least one component selected from the group consisting of device for HV distribution, contactor, fuse, precharge circuit, and current sensor.

4. The HV-battery of claim 1 , wherein the cell modules in the assembled state, the printed circuit board, and the frame have substantially a same width and length.

5. The HV-battery of claim 3 , wherein the outlet box or splitting box has a same size or a same contact spacing as the cells modules.

6. A motor vehicle, comprising a HV-battery including a printed circuit board, a plurality of cell modules configured as plug-in modules for detachable securement to the printed circuit board so as to establish a modular configuration of the HV-battery, each of the cell modules including plural cells, a plurality of controls, operably connected to the cell modules in one-to-one correspondence, for cell monitoring or cell balancing, a battery management control unit, connected to the controls, for communication or open-loop or closed-loop control purposes, and a frame for arrangement of said management control unit, wherein one member selected from the group consisting of the cell modules and the printed circuit board has projections or latching elements for engagement in recesses of the other member of the group, wherein the cell modules are arranged side-by-side in a longitudinal direction and have a joint upper surface and a joint lower surface spaced from one another in a transverse direction, said joint lower surface of the cell modules being fully covered by the printed circuit board, and said joint upper surface of the cell modules being fully covered by the frame.

7. The motor vehicle of claim 6 , wherein the HV-battery is configured for use as a traction battery.

8. The motor vehicle of claim 6 , wherein the HV-battery includes an outlet box or splitting box in the form of a plug-in module which includes at least one component selected from the group consisting of device for HV distribution, contactor, fuse, precharge circuit, and current sensor.

9. The motor vehicle of claim 6 , wherein the cell modules in the assembled state, the printed circuit board and the frame have substantially a same width and length.

10. The motor vehicle of claim 8 , wherein the outlet box or splitting box has a same size or a same contact spacing as the cells modules.
