A battery module with improved heat release, a battery pack containing the battery module, and a vehicle containing the battery pack.

摘要

Provided are a battery module in which heat release is improved by causing electronic cooling at a specific voltage or higher, a battery pack containing the battery module, and an automobile including the battery pack. The battery module according to the present invention includes a plurality of battery cells, and in a battery module in which a lead joint in which the leads of the battery cells are joined to each other is formed, a thermoelectric element attached to the lead joint and a thermoelectric element. A constant voltage element that diverges the current of the battery module to the thermoelectric element side when an overvoltage of the battery module is generated is further included, and when an overvoltage is generated in the battery module, the thermoelectric element is driven to drive the battery module. It is characterized by electronically cooling the lead joint.
