1. A battery module, comprising:
a plurality of battery cells, wherein each battery cell comprises a battery top cover, a positive electrode terminal, a negative electrode terminal, and a temperature sampling region is disposed on the battery top cover and between the positive electrode terminal and the negative electrode terminal;
an electrical connecting plate, configured to connect to different battery cells;
a thermally conductive sampling piece, fixed to the temperature sampling region of the battery top cover to fit with the temperature sampling region of the battery top cover, the thermally conductive sampling piece comprises a sampling board;
a thermally conductive connecting plate, wherein one end of the thermally conductive connecting plate is fixed to the sampling board of the thermally conductive sampling piece to fit with the sampling board;
a circuit board, disposed above the battery top cover, wherein another end of the thermally conductive connecting plate is connected to the circuit board; and
a thermometric element, electrically connected to the circuit board, disposed above the circuit board, and not overlapping the temperature sampling region, wherein the thermometric element is configured to collect a temperature signal of the thermally conductive connecting plate and transmit the temperature signal to the circuit board, and the heat in the temperature sampling region on the surface of the battery top cover is conducted horizontally and vertically to the thermometric element on the circuit board through the thermally conductive sampling piece and the thermally conductive connecting plate.
