此外，下面所描述的本发明不同实施例中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
本发明的发明人在实现本发明的过程中发现：电池工作时，受电池单体排布的影响，靠近边缘区域的电池单体普遍温度较低，同时，由于电池的传热是由电池中心向边缘传递，中间区域的电池单体由于热积累导致散热较慢，因此，边缘区域的电池单体和中间区域的电池单体之间会形成较大的温度差。因此，需要分别对不同区域的电池单体进行温度管理，以保证电池的性能。
请参阅图1，本发明其中一实施例提供一种电池100，包括电池模块10和热管理部件20，电池模块10设于热管理部件20上，热管理部件20用于为电池模块10调节温度，这里的调节温度可以指升温或降温。

热管理部件20还包括相互隔离的第一进口203和第二进口204。第一进口203与第一流道201的一端连通，第一进口203用于向第一流道201输入流体。第二进口204与第二流道202的一端连通，第二进口204用于向第二流道202输入流体。

请一并参阅图9和图10，在一些实施例中，第一进口管道220和第二进口管道222通过总进口管道224连接，总进口管道224与外部的换热器连接，流体从总进口管道224分别输入第一进口管道220和第二进口管道222。其中，第一开关230设于第一进口管道220和总进口管道224之间，第一开关230控制第一进口管道220和总进口管道224之间的通断，从而控制第一流道201与第一进口管道220之间的通断。第二开关232设于第二进口管道222和总进口管道224之间，第二进口管道222控制第二进口管道222和总进口管道224之间的通断，从而控制第二流道202与第二进口管道222之间的通断。
