Abstract
A battery system that is formed from a plurality of battery cells arranged on a flexible printed circuit card, where the flexible printed circuit card is folded along an axis forming an upper and lower portion of the flexible circuit card. A visco-elastic shock-absorbing member installed between the upper and lower portion of the flexible circuit card. Each battery cell may also have a visco-elastic shock-absorbing member that is attached individually to each battery cell of the plurality of battery cells.
Claims20
A conformal wearable battery comprising:
- a plurality of non-cylindrical shaped polymer battery cells;
- and
- a flexible printed circuit board (PCB) comprising:
- a plurality of physical connection sections disposed in a grid like pattern, wherein each of the plurality of battery cells is physically affixed to the flexible PCB at a corresponding physical connection section of the plurality of physical connection sections;
- and
- a bend axis that facilitates folding of the flexible PCB to form an upper portion of the flexible PCB and a lower portion of the flexible PCB;
- a visco-elastic central shock-absorbing member positioned between the upper portion and the lower portion of the flexible PCB preventing the upper portion from contacting the lower portion, wherein the central shock-absorbing member electrically insulates the upper portion from the lower portion;
- and
- a flexible housing that includes an internal cavity that receives the plurality of battery cells, the flexible PCB, and the central shock-absorbing member.
