本发明人注意到，随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。在车辆的开发过程中，电池的布置是一个难点。由于传统汽车零部件众多，在不大量改动车身的情况下，已经没有什么空间用于电池的安装。在进一步研究之后发现，常规的车辆一般将电池放在前舱或后备箱，通过支架安装在车辆的纵梁或者备胎池内，导致支架悬臂梁的模态较弱，易产生噪音，并且电池与供电装置的多个电子模块通常是分开布置的，占用了大量空间，例如占据前舱的电驱或热管理空间等，降低了空间利用率。
鉴于此，本申请提供了一种技术方案，在该技术方案中，壳体用于安装于车辆的车身，壳体包括壳本体、第一安装部件和第二安装部件，壳本体具有容纳腔；第一安装部件设置于壳本体，用于将电池固定于容纳腔内；第二安装部件设置于壳本体，用于将多个电子模块固定于容纳腔内。上述方案中，通过壳体的第一安装部件和第二安装部件可分别将电池以及多个电子模块固定在壳体的容纳腔中，然后将壳体固定于车辆中，电池与 多个电子模块作为一个整体安装于车辆的车身，可提高车辆的空间利用率，而且可提高电池的模态，减小车辆噪音。
