Voltage sensing assembly and battery module including the same

A voltage sensing assembly configured to be mounted to a battery module comprising a plurality of battery cells connected in series to each other for measuring voltage of the battery cells, the voltage sensing assembly comprising:

• sensing bus bars configured to be connected to series connection portions of the battery cells for sensing the voltage of the battery cells;
• a printed circuit board (PCB), to an upper part of which the sensing bus bars are coupled in a state in which the sensing bus bars are arranged at equal intervals and to a lower part of which a connector is coupled;
• the connector mounted on the PCB for transmitting the sensed voltage to a battery management system (BMS);
• an insulative mounting member having a cross-sectional shape of an interior surface thereof that is substantially equal in size to a cross-sectional shape of the PCB when viewed from a front view of the insulative mounting member and the PCB, wherein the PCB is mounted in the insulative mounting member, and wherein the insulative mounting member is provided at a top surface thereof with openings through which the sensing bus bars extend;
• and
• an insulation sheet, separate from the insulative mounting member, having a cross-sectional shape substantially the same as the cross-sectional shape of the PCB, the insulation sheet being provided with an opening having a shape substantially the same as a shape of the connector, and the insulation sheet being attached to a front surface of the PCB.
