AI Technical Summary
Technical Problem
The existing battery pack without module structure is difficult to decompose into battery cell units during maintenance, resulting in the need to discard the entire battery pack when there is a problem with a single battery cell.
Method used
A battery pack is designed in which the battery cell assembly has a fixed side frame, the side frames of adjacent components share the upper surface of the beam and facilitates easy assembly and maintenance by entrainment and paste-like gap filler.
Benefits of technology
It realizes easy removal and replacement of any battery cell assembly, avoids the situation of discarding the entire battery pack due to the problem of single battery cell, and extends the service life of the battery pack.

Abstract
In one example, a battery pack includes: a base plate; a side plate coupled along an outer periphery of the bottom plate to form an accommodation space therein; a cross beam coupled to the base plate and dividing an accommodation space inside the base plate in a width direction; and a plurality of battery cell assemblies installed in the accommodating space divided by the cross beam, in which the battery cell assemblies have side frames fixed to the cross beam, and the side frames of the battery cell assemblies adjacent in the length direction share an upper surface of the cross beam located therebetween and do not overlap each other vertically.
