当然，也可以根据实际需求来设计换热器、气体流速调节器、流量调节器和加热器的设置数量以及设置位置。本申请只是提出几个优选实施例，并不能理解为对本申请的限制。
在本申请的一些实施例中，储能电池包的温度管理方法还包括：获取外界环境温度以及用电设备工况，根据外界环境温度和用电设备工况调节第一温度值和/或第二温度值和/或第三温度值和/或第四温度值；
和/或，通过云服务器调节第一温度值和/或第二温度值和/或第三温度值和/或第四温度值。
需要说明的是，第一温度值、第二温度值、第三温度值以及第四温度值不是一个定值，由于相变介质的特性，相变介质的吸热、放热能力与外界环境温度具有一定的关系，并且，用电设备的工况对储能电池的温度控制也具有一定的要求。
例如，若此时用电设备处于剧烈的工作状态下，储能电池的温度会以较快的速度升高，此时需要快速对储能电池进行降温，因此，控制模块可以根据用电设备的工况适当调低第二温度值和第四温度值，以便于快速触发相变介质流动以及气体流速调节器工作。
再例如，若此时外界温度非常低，并且储能电池的温度处于较低状态时，需要快速对储能电池进行升温，因此，控制模块可以根据外界环境温度适当调高第一温度值和第三温度值，以便快速触发相变介质流动以及加热器工作。
如此设置可以根据外界环境温度和用电设备工况调节第一温度值和/或第二温度值和/或第三温度值和/或第四温度值，从而能够可靠的调节储能电池的温度。
此外，云服务器可以远程获取用电设备工况以及用电设备所处地的环境温度，并根据用电设备工况以及用电设备所处地的环境温度调节第一温度值和/或第二温度值和/或第三温度值和/或第四温度值。如此设置当遭遇极端环境温度或者极端工况，超出用电设备预设的算法或者控制参照表所能处理的范围时，可以通过云服务器远程操控，从而能够更加可靠的调节储能电池的温度。
具体地，如图2所示，作为本申请的一个具体实施例，上述的温度管理方法可以包括以下步骤：
S01,获取储能电池的温度；
S02,判断储能电池的温度是否处于第一预设温度区间外；
S03,判断储能电池的温度是否满足关系式：第一温度值≤储能电池的温度＜第二温度值；
S04,通过相变介质调节储能电池的温度；
S05，判断储能电池的温度是否满足关系式：储能电池的温度≥第二温度值；
S06，控制相变介质循环流动并通过换热器；
S07，判断储能电池的温度是否满足关系式：储能电池的温度≥第四温度值；
S08，控制气体流速调节器工作；
S09，判断储能电池的温度是否满足关系式：储能电池的温度＜第一温度值；
S10，控制相变介质循环流动；
S11，判断储能电池的温度是否满足关系式：储能电池的温度＜第三温度值；
S12，控制加热器工作。
其中，在步骤S02中，若判断是，则进入步骤S03，若判断否，则返回步骤S01。在步骤S03中，若判断是，则进入步骤S04，若判断否，则返回步骤S01。在步骤S05中，若判断是，则进入步骤S06，若判断否，则返回步骤S03。在步骤S07中，若判断是，则进入步骤S08，若判断否，则返回步骤S05。在步骤S09中，若判断是，则进入步骤S10，若判断否，则返回步骤S03。在步骤S11中，若判断是，则进入步骤S12，若判断否，则返回步骤S09。
