Abstract
The present application provides a bus member, a battery and a power consumption device, and relates to the technical field of batteries. The bus member includes a first connection portion configured to be connected to a first electrode terminal of a first battery cell; a second connection portion configured to be connected to a second electrode terminal of a second battery cell; and a plurality of fusing portions, one end of each fusing portion being connected to the first connection portion, and the other end being connected to the second connection portion; where an overcurrent cross-sectional area corresponding to one of the plurality of fusing portions with a maximum is expressed as S, and with a minimum is expressed as S, Sand Ssatisfy: 0.3≤S/S≤1 and 0.3≤S/S≤1, thus avoiding accumulation of arc energy of the fusing portions due to a long-duration short circuit.
