Abstract
A battery system which includes a plurality of cylindrical cells, including a first cylindrical cell and a second cylindrical cell, an electrical tab that is connected to the first cylindrical cell and the second cylindrical cell using spot welding, and a battery management printed circuit board, where the electrical tab provides a connecting surface for a battery management signal between (1) the first cylindrical cell and the second cylindrical cell and (2) the battery management printed circuit board.
Claims21
A battery system, comprising:
- a first end plate including a plurality of cutouts;
- a plurality of cylindrical cells, including a first cylindrical cell and a second cylindrical cell;
- an electrical tab fitting entirely within a cutout of the plurality of cutouts wherein the cutout is a single cutout, wherein the cutout exposes one terminal end of the first cylindrical cell and one terminal end of the second cylindrical cell, and wherein the electrical tab is connected to the first cylindrical cell and the second cylindrical cell using spot welding;
- and
- a battery management printed circuit board, wherein the electrical tab provides a connecting surface for a battery management signal between (1) the first cylindrical cell and the second cylindrical cell and (2) the battery management printed circuit board.
