Battery module and vehicle provided with same

Abstract

The invention discloses a battery module and a vehicle provided with the same. The battery module comprises a battery fixing support frame, a series-connection busbar, axial heat conduction structures, an average-temperature heat conduction pad and a heat exchange plate, wherein multiple cylindrical battery cells are arranged on the battery fixing support frame; the series-connection busbar is arranged at one side of the battery fixing support frame and is used for connecting the multiple cylindrical battery cells in series, and an end face of the series-connection busbar, opposite to the cylindrical battery cells, protrudes outwards so as to form grooves between end faces of the cylindrical battery cells and the series-connection busbar; the axial heat conduction structures are arranged in the grooves; the average-temperature heat conduction pad is pasted on the series-connection busbar and are laminated with the multiple axial heat conduction structures; and the heat exchange plate and the average-temperature heat conduction pad are arranged by laminating. According to the battery module disclosed by the invention, efficient balanced heat management of the battery cell temperature can be achieved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular, to a battery module and a vehicle having the same. Background technique [0002] As electric vehicles become more and more widely used, the battery system, which is the core of electric vehicles, has stricter requirements on operating temperature. Too high or too low working temperature will lead to the decline and reduction of system performance and life. With the gradual improvement of the performance and battery life requirements of electric vehicles, the energy density of battery systems and battery modules is also increasing, which leads to the accumulation of heat in the modules, especially for the battery system with a large number of batteries. The heat transfer is relatively poor, so its heat Management is more difficult. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at leas...
