1. A battery module, comprising:
a plurality of battery cells connected in series or connected in series and in parallel;
a plurality of bus bars connected to corresponding electrode leads of the battery cells, each busbar having a respective keyway, wherein the keyway is a hollowed-out space formed in the busbar, wherein the hollowed-out space is recessed from a surface of the busbar; and
a voltage sensing member having a plurality of sensing parts, each sensing part respectively connected to a corresponding bus bar in a one-to-one correspondence and including:
a terminal portion having a shape configured to fit inside the keyway; and
a bonding portion configured to cover over the terminal portion so as to fix the terminal portion within the keyway.
