AI Technical Summary

Technical Problem

In existing battery packs, due to insufficient design space and location, fuses and maintenance switches cannot be installed in collision accidents. As a result, when the high-voltage system is symmetrically distributed, only half of it has fuses and the other half does not, which poses a risk of battery pack fire and occupies design space, affecting structural strength.

Method used

Design a fusible battery module connector with multi-layer connectors and a honeycomb fusible structure. The connectors are covered with insulating material at both ends and have a raised part in the middle. Combined with a cooling unit, the temperature is reduced, enabling rapid fusing and disconnection of the high-voltage system.

Benefits of technology

It effectively reduces the probability of short circuit fires caused by collisions in the battery pack, avoids the risk of battery pack fires, and does not require additional design space, thus improving the safety and structural strength of the battery pack.

Abstract

The utility model discloses a kind of battery module connecting row of fusing, including connecting row main body, the positive pole between the negative pole of connecting row main body two ends is connected respectively between battery module, the connecting row main body includes the connecting sheet of multilayer parallel arrangement, both ends of the connecting sheet are covered with insulating substance, middle part is equipped with protruding part, protruding part is equipped with honeycomb-like fuse structure.Such, it solves the risk battery pack that fuse and maintenance switch cannot be installed due to insufficient design space and position, also solves the problem that large battery pack high-voltage system symmetrical distribution can only be connected with a fuse in half high-voltage system, the other half high-voltage system does not cause battery pack fire risk, simultaneously without considering the position of design installation fuse and other problems, greatly reduce the probability of battery pack short-circuiting fire accident caused by battery pack due to automobile collision accident.
