Abstract

Multi-dimensional battery networks are presented that are intrinsically superior to the standard battery networks that are currently being used in electric vehicle applications. The higher dimensional battery networks are more stable against failures in individual batteries. The networks can be implemented using Li-ion batteries and enhance the lifetime of battery networks, which is critically important, for example in automotive applications.

First claim

What is claimed is:

1. A multi-dimensional battery network comprising:
a plurality of individual battery cells being electrically connected in a three-dimensional periodic network, the plurality of individual battery cells being electrically arranged in at least first through fourth rows, first through fourth columns, and first through fourth planar levels such that:
the first through fourth battery cells in every column are electrically coupled in series resulting in first, second, and third nodes therebetween;
the third and fourth battery cells of every column on the first planar level are electrically coupled at the third node to the third and fourth battery cells of the corresponding column on the second planar level, the first and second battery cells of every column on the second planar level are electrically coupled at the first node to the first and second battery cells of the corresponding column on the third planar level, the third and fourth battery cells of every column on the third planar level are electrically coupled at the third node to the third and fourth battery cells of the corresponding column on the fourth planar level,
the second and third battery cells of the second column on every planar level are electrically coupled at the second node to the second and third battery cells of the third column of the corresponding planar level, and
each of said plurality of individual battery cells being operable to output stored energy between a network positive terminal and a network ground terminal.

2. The multi-dimensional battery network according to claim 1 wherein said plurality of individual battery cells are each Li ion battery cells.

3. The multi-dimensional battery network according to claim 1
wherein each of the nodes electrically couples at least and no more than four of said plurality of individual battery cells such that failure of one of said four individual battery cells does not substantially affect operation of said plurality of individual battery cells other than said four individual battery cells.

4. A battery network comprising:
a plurality of individual battery cells each being operable to output stored energy between a network positive terminal and a network ground terminal, the plurality of individual battery cells being electrically arranged in a two-dimensional periodic network in at least first through three rows and first through fourth columns such that:
the first through three battery cells in every column are electrically coupled in series resulting in first and second nodes therebetween; and
the second and third battery cells of the first column are electrically coupled at the second node to the second and third battery cells of the second column, the first and second battery cells of the second column are electrically coupled at the first node to the first and second battery cells of the third column, the second and third battery cells of the third column are electrically coupled at the second node to the second and third battery cells of the fourth column.

5. The battery network according to claim 4 wherein said plurality of individual battery cells are each Li ion battery cells.

6. The battery network according to claim 4
wherein each of the nodes electrically couples at least and no more than four of said plurality of individual battery cells such that failure of one of said four individual battery cells does not substantially affect operation of said plurality of individual battery cells other than said four individual battery cells.
