Discussed is a battery module which includes: a battery cell stack in which a plurality of battery cells are stacked; a lower frame that covers a lower surface and both side surfaces of the battery cell stack; an upper frame that covers an upper surface of the battery cell stack; busbar frames that respectively cover front front and rear surfaces of the battery cell stack; and a connector that connects the busbar frame at the front surface with the busbar frame at the rear surface, wherein the connector is formed of a flexible flat cable (FFC) and attached to the upper frame.

Battery module and battery pack including the same

The present disclosure provides a battery pack including a battery cell array in which a plurality of battery cells are arranged in a state in which side surfaces thereof face each other, a heater disposed between the battery cells, a battery management system (BMS) configured to control an operation of the battery cells, and a temperature sensor configured to measure a temperature of the battery cells to transmit the measured temperature to the BMS. Here, when the temperature of the battery cells, which is measured from the temperature sensor, is equal to or less than a critical temperature, the BMS provides a current to the heater to increase the temperature of the battery cells.
