发明内容
本发明的目的在于克服上述不足，提供了一种可自由组合堆叠式户用储能电源，电池模组的电芯采用卧式设置，相邻电芯的连接部件及采样板设置在电芯的侧面，降低了电池模组的高度，从而降低了中间箱及顶箱的高度，有效利用不充裕的安装空间以实现最大化增加储能电源系统容量以满足使用需求，大大提高了空间利用率。
本发明的目的是这样实现的：
一种可自由组合堆叠式户用储能电源，包括底座、中间箱和顶箱，多个中间箱自下至上依次堆叠于底座上，顶箱堆叠于最上方的中间箱上，所述中间箱和顶箱内设有多个电池模组，所述中间箱和顶箱的内侧壁对应电池模组设有安装台阶，所述电池模组包括电芯、钢带、端板和转接板，所述电芯卧式设置，多个电芯及两侧端板由钢带捆扎在一起，所述转接板呈簸箕型，所述转接板搁置在安装台阶上；

优选的，所述转接板的底面通过螺栓与端板连接，侧围套设在安装台阶上，且侧围与安装台阶之间通过螺栓连接。
优选的，相邻中间箱之间、最上方的中间箱与顶箱之间均设有浮动连接器，所述浮动连接器包括浮动连接器公头和浮动连接器母头，所述顶箱和中间箱下端面设有浮动连接器母头，所述中间箱的箱盖对应浮动连接器母头设有浮动连接器公头，底座的上端面对应浮动连接器母头设有避让孔。
优选的，在顶箱和中间箱的下端面向内凹陷设有容纳槽，在底座的上端面和中间箱的箱盖均向外凸出设有限位台阶，所述容纳槽与限位台阶相配合。
优选的，在电池模组上方还盖设有PC防火片，PC防火片将各电芯及采样板罩住。
优选的，所述顶箱设有电量显示屏及用于连接外接设备的插口。
本发明的有益效果是：
内置电池模组的中间箱及顶箱之间通过浮动连接器电连接，无需外接电线，不易短路，安全系数高，组装便捷；
电池模组的电芯采用卧式设置，相邻电芯的连接部件及采样板设置在电芯的侧面，降低了电池模组的高度，从而降低了中间箱及顶箱的高度，有效利用不充裕的安装空间以实现最大化增加储能电源系统容量以满足使用需求，大大提高了空间利用率；
