Battery module

A battery module, comprising:

• a plurality of secondary batteries disposed in a row and provided with explosion-proof valves;
• an insulating plate disposed above the secondary batteries;
• a monitoring cable set connected with the insulating plate;
• and
• a battery management system,
• wherein the monitoring cable set is corresponding to a position of each of the explosion-proof valves;
• the monitoring cable set comprises two monitoring cables respectively connected with a positive terminal and a negative terminal of the battery management system;
• each of the two monitoring cables comprises a wire and a thermomelting insulating layer cladding the wire;
• when the explosion-proof valve of any of the secondary batteries explodes, the thermomelting insulating layers of the two monitoring cables melt, and two wires respectively in the two monitoring cables are in contact with each other and short-circuited;
• and
• wherein the battery management system is configured to take safety measures when monitoring a current change signal due to a short circuit of the two wires.
