正如背景技术中所公开的，针对应用在储能集装箱中，两端出极柱的铝壳电芯所组成的电池模块，在使用时会发热，温度过高和较大的温差会对电池寿命有较大影响。同时，两端出极柱的铝壳电芯所组成的电池模块通常电量和体积均较大，形式接近汽车动力电池包，且不提供预紧力，结构稳定性差。储能用电池模块通常安装在集装箱后，会外露较多的高压电气连接和低压信号连接，存在安全隐患，也不美观。并且，常规的电池模块，采用的是一体式结构，即电气部件直接安装在电池模组上，集成度较差，安装繁琐，不利于快速组装，且安全性较低，不利于单独更换各个部件。同时，常规的电池模块内电池组采用直接叠装方式，当发生热失控时，容易造成较快的热蔓延，影响热失控下模块安全。
为了解决上述问题，本申请提供了一种新型的模块化储能电池，其采用模块化的结构形式，组装方便且安全性高。下面对该模块化储能电池进行详细说明。

在本实施例中，进风筛孔包括第一进风筛孔1131、第二进风筛孔1141以及第三进风筛孔1151，左侧板113上远离固定框130的一端设置有第一进风筛孔1131，右侧板114远离固定框130的一端设置有第二进风筛孔1141，盖板115远离固定框130的一端设置有第三进风筛孔1151，前端板112的上下两侧都形成有与容置内腔导通的出风口，出风口与风扇152对应设置，第一进风筛孔1131、第二进风筛孔1141和第三进风筛孔1151与导风间隙导通。具体地，第一进风筛孔1131、第二进风筛孔1141和第三进风筛孔1151均呈蜂窝状通孔结构，并且第一进风筛孔1131靠近左侧板113的尾部设置，第二进风筛孔1141靠近右侧板114的尾部设置，第三进风筛孔1151靠近盖板115的尾部设置。

参见图8，电池组111包括多个泡棉1111、多个隔热垫1113以及多个层叠设置的电芯1115，每个泡棉1111贴装在相邻两个电芯1115之间，每个隔热垫1113也贴装在相邻两个电芯1115之间，且多个泡棉1111和多个隔热垫1113交错设置，每相邻两个电芯1115之间均设置有泡棉1111或隔热垫1113。具体地，电池组111由电芯1115、泡棉1111、隔热垫1113组成，此处以三片电芯1115为例进行说明，具体实施时第一片电芯1115的大面(即较大的侧面)和第二片电芯1115的大面之间贴泡棉1111，第二片电芯1115的大面和第三片电芯1115的大面之间贴隔热垫1113，如此依次组装，泡棉1111和隔热垫1113交替使用在电芯1115的大面之间。电芯1115的大面之间夹泡棉1111，泡棉1111可有效地吸收电芯1115生命周期内的膨胀，同时泡棉1111提供的反弹力作为电池模组110组装时的预紧力，有助于电池模组110的结构稳定。电芯1115的大面之间夹隔热垫1113，隔热垫1113可以有效地隔断发生热失控的电芯1115和正常电芯1115之间的热传递，防止发生热蔓延，保证电池模组110的安全。
当然，在其他较佳的实施例中，也可以两片或多片电芯1115之间贴一片泡棉1111，隔热垫1113和泡棉1111仍交替使用。此处对于泡棉1111和隔热垫1113的交错形式，并不做具体限定。
综上，本实施例提供了一种模块化储能电池100，将固定框130可拆卸地设置在电池模组110的一端，电气集成模组150嵌设安装在固定框130内，同时面板170可拆卸地设置在电气集成模组150上，通过将面板170、电气集成模组150和固定框130集成化安装，并可拆卸地安装至电池模组110的端部，实现了模块化结构，在需要更换或维修时可以直接将固定框130拆下，十分方便。而在实际安装时，可以先将电气集成模组150嵌设安装在固定框130内，并安装完成面板170，形成模块结构，然后再将该模块结构安装在电池模组110的一端，十分方便。并且也能够方便更换单独的部件，易于加工组装，避免了将电气部件153依次直接安装在电池模组110的端面上，使得电池模组110的端面结构更加简化，也降低了制造成本。同时通过面板170对电气集成模组150进行遮挡，能够避免外 露较多的电气结构，提升了安全可靠性。同时通过设计风扇152进行风冷，并对风道进行改进设计，使得其散热效果良好，能够快速带走电池模组110产生的热量。并且，通过对电池组111的结构设计，使得其具备良好的预紧力和防止热蔓延的能力，保证了电池模组110的安全。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
