Abstract
A round cell rechargeable battery includes a plurality of round cells arranged alongside one another and at least one output element that is electrically insulated from the round cells. The at least one output element is in the form of a rod and is curved such that the output element runs in a zigzag shape alternately along a lower face, a side wall adjacent thereto, and an upper face of the round cells and thermally conductively connects a group of the round cells for heat dissipation.
Claims12
A round cell rechargeable battery comprising:
- a plurality of round cells arranged alongside one another, each of the round cells comprising a lower face at a first end of the round cell and an upper face provided at a second end of the round cell opposite the first end, the upper and lower faces connected by a side wall, the upper face having at least one pole connection;
- at least one heat sink element that is electrically insulated from the round cells;
- wherein the at least one heat sink element is in the form of a rod and is curved such that the heat sink element runs in a zigzag shape alternately along the lower face, the side wall adjacent thereto, and the upper face of the round cells and thermally conductively connects a group of the round cells for heat dissipation.
