HEATING SHEET AND BATTERY MODULE

A heating sheet and a battery module (100) are provided. The battery module (100) includes multiple battery cells (110) and a heating sheet (120). The heating sheet (120) includes multiple heating units (121) and multiple connection units (130), and two adjacent heating units (121) are coupled with each other through a connection unit (130). One heating unit (121) may be attached to a side wall of one battery cell (110), and the connection unit (130) corresponds to the gap region. The connection unit (130) has a heat productivity per unit area less than the heating unit (121), such that heat of the heating sheet (120) corresponding to a gap region is reduced, and "dry burning" caused by the heat of the heating sheet (120) corresponding to the gap region being unable to be transferred to the battery cell (110) in a direct contact manner is effectively avoided, thereby avoiding a situation that the heating sheet (120) is damaged due to local overheating.
