Battery module with high thermal conductivity and assembling method thereof

摘要

A battery module with high thermal conductivity and its assembling method are disclosed. The battery module includes multiple battery cells, a primary retaining frame, a secondary retaining frame, common electrodes and a heatsink device. The primary and second retaining frames are combined together to constitute accommodation chambers for housing the battery cells and formed with interference flanged to secure the battery cells in position. Upon being inserted into the accommodation chambers, the battery cells are electrically connected to the common electrodes. The heatsink device is then coupled to the primary retaining frame and/or the secondary retaining frame, such that the heatsink device abuts against the top common electrode and/or the bottom common electrode of the battery cells.

1. A method for assembling a battery module with high thermal conductivity, the battery module having multiple battery cells, each comprising a top surface with a metal region served as a top electrode, a bottom surface with a metal region served as a bottom electrode, and a sidewall connecting the top surface to the bottom surface, with the top and bottom electrodes being electrically insulated from each other, the assembling method comprising the steps of:
a) providing a primary retaining frame having a plurality of retaining holes, and a secondary retaining frame having a plurality of accommodation holes, that together define a plurality of accommodation chambers for housing the respective battery cells, each of the plurality of accommodation chambers housing a solitary respective battery cell, and inserting the respective battery cells into the accommodation chambers corresponding thereto; and b) electrically connecting the top electrodes and bottom electrodes to a top common electrode or a bottom common electrode, respectively, and coupling a heatsink device to the primary retaining frame and/or the secondary retaining frame, such that the heatsink device abuts against the top common electrode and/or the bottom common electrode of the battery cells.
