Battery Assembly

摘要

A battery assembly that includes a plurality of batteries. The battery assembly includes a printed circuit board integrated with plural fuses and resistors. The sizes of the resistors vary based on a distance between the batteries and a connection point to compensate for resistance differences from each battery to the connection point.

1. A battery assembly, comprising:
a first printed circuit board (PCB) having a plurality of first conductive shapes arranged in a matrix-shape; a second PCB oppositely disposed from the first PCB and having a plurality of second conductive shapes arranged in a matrix-shape; a plurality of first springs disposed on the first conductive shapes of the first PCB; a plurality of second springs disposed on the second conductive shapes of the second PCB; a plurality of batteries stacked between the first and second PCBs in a side-by-side relationship each having a first end in electrical contact with one of the first springs on the first PCB and a second end in electrical contact with one of the second springs on the second PCB; a plurality of fuses integrally formed in the second PCB, each of the fuses electrically connected with one of the second conductive shapes; and a plurality of compensation traces each connected with one of the fuses and a bus line where a current flow along, wherein sizes of the compensation traces vary based on a distance between the second conductive shapes and a connection point on the bus line to compensate for resistance differences from each battery to the connection point.
