Battery module and apparatus

A battery module, comprising:

• a plurality of battery units arranged side by side along a length direction of the battery module, and each of the battery units comprising a top cover;
• a circuit board disposed above the top cover in a height direction, the circuit board being provided with a temperature collection circuit;
• a heat-conducting element, a first end of the heat-conducting element being connected to the circuit board, and at least part of the heat-conducting element being in contact with the top cover;
• a temperature detection component disposed on the heat-conducting element and signal-connected to the temperature collection circuit, the temperature detection component being configured to collect a temperature of the top cover;
• a wire harness board disposed on the top cover along the height direction, the wire harness board comprising a mounting base, wherein the circuit board is disposed on the wire harness board, and a second end of the heat-conducting element is disposed on the mounting base,
• wherein the heat-conducting element comprises:
• a first bending portion configured to be at least partially in contact with the top cover;
• and
• a first mounting portion and a second mounting portion, respectively located at two ends of the first bending portion along a width direction of the battery module, and configured to be fixed to the wire harness board, and an end of the first mounting portion away from the first bending portion serving as the first end of the heat-conducting element and being fixed to the circuit board and mounted with the temperature detection component;
• wherein the first bending portion is convex downward relative to a plane where the first mounting portion and the second mounting portion are located.
