The invention discloses a square aluminum shell battery module, which comprises a plurality of square aluminum shell battery cells arranged in a multi-column laminated manner; battery cell heat insulation layers attached to the side faces of the square aluminum shell battery cells, wherein the battery cell heat insulation layers are attached to the two side faces of each square aluminum shell battery cell; battery cell insulation paper adhered to the tops of the square aluminum shell battery cells, wherein through holes for pole columns of the square aluminum shell battery cells to extend outare formed in the battery cell insulation paper; module series-parallel connection copper plates locked and fixed on the pole columns to connect the plurality of square aluminum shell battery cells; heat-conducting insulating pads attached to the module series-parallel connection copper plates; and a heat dissipation plate pressed against the other surfaces of the heat-conducting insulating pads.The square aluminum shell battery cells on the inner side and the outer side of the square aluminum shell battery module have the same heat dissipation physical field, the temperatures of the batterycells on the inner side and the outer side of the module are nearly consistent, the temperature consistency between the battery cells during charging and discharging recycling is improved, and the service life of the battery module is prolonged.
Description
technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a square aluminum shell battery module. Background technique [0002] In the application of new energy batteries, the consistency control of cells is the key technology for grouping cells, and the consistency control also includes two aspects. One is the consistency of battery basic performance matching, including capacity, voltage, internal resistance, self-discharge, etc.; the other is the consistency control of the battery cell use environment, the most important of which is the consistency of charge and discharge temperature. [0003] In the application of energy storage systems, square aluminum shell batteries are the mainstream application. In the existing square aluminum shell energy storage system battery pack design, the heat dissipation method generally uses the metal outer surface of the square aluminum shell for heat dissipation. However, in the group de...
