根据本申请的另一个方面，本申请进一步提供了电芯支架组及储能装置封装件的配置方法：将电芯支架组作为电芯载体，设置电芯于电芯支架组中并固定，通过支架的堆叠实现储能装置模组的构建。在堆叠后，通过挤压设备对模组施加压力进行压缩，并在压缩状态下自储能装置模组的两侧套入钢带，待钢带套入指定位置后慢慢降低所施压力，钢带恢复到拉紧状态，实现储能装置模组的固定。随后通过结合件将储能装置模组与封装外壳结合固定。
在一些实施例中，结合件可以是本领域任何常用的结合件，例如，但不限于，螺拴、粘结、扣榫。
基于上述说明可知，本申请提供了一种电芯支架组以及包含所述电芯支架组的储能装置封装件，通过其结构的改进，本申请实施例的电芯支架组及储能装置封装件可以大幅的提升储能装置的散热效能，同时降低其重量，此外，本申请的电芯支架组及储能装置封装件提供了可调节电芯数量、配置以及电量输出的设置，可以提供使用者更有弹性及客至化的储能装置模组。同时，本申请储能装置封装件还具有组装容易、搬运方便、制备成本低等多种好处。
