Abstract

The invention relates to the field of battery modules, and provides a battery module. The battery module comprises at least two busbars, at least one heating resistor connected between two adjacent busbars, and at least two safety structures electrically connected between the heating resistor and the busbars, and when the temperature of the heating resistor is higher than the melting point temperature of the safety structures, the safety structures can be fused and enables the heating resistor to be disconnected from the busbars. According to the battery module, when the current flowing through the heating resistor is too large, the safety structures can be fused through the heating amount of the heating resistor, so that the mechanical connection relation and the electric connection relation between the heating resistor and the busbars are disconnected in real time, the overcurrent phenomenon is interrupted in real time, heat accumulation is hindered, the risks of explosion, fire and the like of the battery module are reduced, and the safety performance of the battery module can be improved. And the safety performance of the battery module can be ensured again by additionally welding the safety structure between the heating resistor and the busbars, so that the battery module can be repeatedly used.

Description

technical field [0001] The invention belongs to the technical field of battery modules, and in particular relates to a battery module. Background technique [0002] The battery module is usually equipped with a safety structure at the lead-out of its positive and negative electrodes. The safety structure will be blown when the battery cell is abnormal to prevent the spread of thermal runaway, so as to ensure the safety performance of the battery module. However, the existing insurance structure is easy to be torn off when the positive and negative poles of the module are locked, and the reliability is poor, which affects the safety performance of the battery module; and the insurance structure is scrapped after being fused or torn, resulting in the risk of scrapping the battery module High, poor performance and service life. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a battery module to solve the technical prob...
