在本申请中，所提及的电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提及的电池可以包括电池模组或电池包等。
电池包括箱体和电池模组。箱体包括框架、顶板和底板，电池模组设置于底板，顶板和底板设置于框架以封闭框架上的开口，顶板朝向用电设备中心，底板背离用电设备中心，框架设置有连接机构以连接用电设备的主体。
电池模组由多个电池单体并联或者串连而成，电池单体包括外壳、电极组件和泄压机构，电极组件设置于外壳内，泄压机构设置于外壳。电池单体主要依靠电极组件来工作，泄压机构在电池单体内部压力或温度达到阈值时通过放出电池单体内部气体来泄放电池单体的内部压力。
目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。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。
发明人注意到，电池的电池模组安装于电池的箱体中时，需要在箱体内设置多个辅助部件以保证电池模组稳定的安装于箱体的底板，导致箱体结构复杂、安装繁琐。结构复杂对箱体的推广有不良影响。例如，在电池模组与底板之间设置缓冲垫或者以达到对电池模组进行缓冲减震的效果，或者，在箱体的底板设置固定机构以将电池模组固定于底板上，箱体的内部部件较多，导致箱体的生产成本增加。
为了解决电池的生产成本高的缺点，申请人研究发现，可以在结构上对电池的箱体结构进行简化，具体为改变电池模组在箱体内的安装位置，省去箱体的部分辅助部件。
基于以上考虑，为了解决电池因箱体结构复杂、安装繁琐而导致的高成本低性价比的问题，发明人经过深入研究，设计了一种箱体，通过在箱体的框架内壁设置连接部，并使电池模组通过连接部安装于箱体内，在由该箱体构成的电池中，由于电池模组通过连接部设置于箱体内壁，即使去除辅助部件(如缓冲垫、固定机构等)，电池模组依旧能够稳定安装于箱体，简化了箱体结构和安装步骤，降低箱体的生产成本，有益于箱体的推广。
