Abstract: The present disclosure relates to a battery module and a battery pack. The battery module includes a battery assembly, including a plurality of battery cells arranged in an array, wherein each of the battery cells includes a vent; a circuit board, including a plurality of sampling terminals connected to the battery cells and being capable of collecting electrical parameters and/or temperature parameters of the battery cells; and a thermal cable, located between the battery assembly and the circuit board and fixedly coupled to the circuit board, wherein a thermal circuit is formed inside the thermal cable, and the thermal circuit can provide a prompt signal indicating a bursting of the vent of any of the battery cells. When a thermal runaway of any of the battery cells occur, the corresponding vent bursts to heat the thermal cable, and the thermal cable can quickly sense a temperature change.
