1. A battery module, comprising:
a plurality of battery cells, wherein each battery cell comprises a battery top cover;
a thermally conductive sampling piece, wherein one end of the thermally conductive sampling piece fits snugly with and is fixedly connected to the battery top cover, and the thermally conductive sampling piece is made of metal;
a flexible circuit board, disposed above the battery top cover, wherein another end of the thermally conductive sampling piece is connected to the flexible circuit board; and
a thermometric element, disposed on the flexible circuit board and electrically connected to the flexible circuit board, wherein the thermometric element is configured to collect a temperature signal of the thermally conductive sampling piece and transmit the temperature signal to the flexible circuit board;
wherein each battery cell comprises a top sheet, the top sheet fits snugly with an upper surface of the battery top cover, a temperature collection opening is made on the top sheet, the portion of the battery top cover exposed by the temperature collection opening is a temperature sampling region, and the thermally conductive sampling piece fits snugly with and is fixedly connected to the temperature sampling region.
