附图说明
图1是本发明的模块化可扩展的电池温度调节***的结构框图；
图2是本发明的模块化可扩展的电池温度调节***的一个分支的结构框图。
具体实施方式
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。
需要说明的是，在本发明的描述中，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
如图1所示，本发明的模块化可扩展的电池温度调节***与多个电池相连(如图1所示，电池1-电池N)，该***用于独立地调节所述多个电池的温度。所述电池温度调节***具体包括电控***、冷却液循环泵、热交换器、冷却液存储装置和管路***，所述电控***与所述热交换器和/或所述冷却液循环泵相连以便控制所述热交换器和/或所述冷却液循环泵的操作。如图1所示，所述冷却液循环泵、所述热交换器和所述冷却液存储装置通过所述管路***连接成回路。在本发明的实施方式中，所述管路***包括总管路和多个分支管路，每个所述电池设置在一个所述分支管路上。
继续参阅图1，所述电控***包括控制器和多个温度传感器(图1所示S)，每个所述温度传感器与每个所述电池一一对应地设置在一个所述分支管路上，所述温度传感器检测所在分支管路中的冷却液温度并将信号反馈给所述控制器，所述控制器能够根据所述温度传感器的 检测结果来控制所述冷却液循环泵和/或所述热交换器的操作。具体地，当电池温度过高时，所述控制器打开所述冷却液循环泵，使冷却液循环流过相应分支管路中的电池，带走电池上的热量。同时，所述控制器还打开所述热交换器，使吸收了热量的冷却液在热交换器的水路侧与热交换器内的冷媒进行热交换，并因此使冷却液的温度降低，以便再通过循环泵送到相应分支管路中的电池。
关于控制器，需要指出的是，其可以采用任何适当的硬件、软件、或软硬件结合的形式来实现，并且可以是任何类型的控制器，例如组合逻辑控制器、可编程控制器等。
下面参阅图2，图2是本发明的模块化可扩展的电池温度调节***的一个分支的结构框图。如图2所示，每个所述分支管路上还设置有开度可调的流量阀，所述控制器还能够根据所述温度传感器的检测结果来控制所述流量阀的开度，以便根据电池的温度来决定流过该电池的冷却液的量。本领域技术人员容易理解的是，这种设置使得能够对每块电池独立地进行温度管理，从而最大程度地提高了单块电池的使用寿命。
继续参阅图1，所述电池温度调节***还可以选择性地包括设置在所述总管路中的加热装置，所述加热装置用于在温度过低时对冷却液进行加热。例如，在寒冷的冬天进行冷启动时，不但无需对电池进行冷却，反而需要提高其温度。这时控制器可以关闭热交换器，同时打开加热装置和循环泵，循环泵使加热后的冷却液流过相应支路的电池，以便将电池的温度提升到可工作的程度。
在本发明的优选实施方式中，所述电池既可以是电动汽车的动力电池，也可以是用于给电动汽车充换电的移动充电车上的动力电池或储能电池。当然，所述电池也可以是其他类型的电池，这并不偏离本发明的基本原理和保护范围。
在本发明的优选实施方式中，如图1所示，所述冷却液是水，并且所述冷却液存储装置是水箱。此外，所述冷却液循环泵是循环水泵。或者，所述冷却液也可以是由水和乙二醇混合而成的防冻液。
在本发明的优选实施方式中，所述热交换器可包括压缩机，由压缩机对冷媒进行压缩，同时配合冷凝器(即热交换器室外侧)和蒸发器(即热交换器水路侧)对上述冷却水进行降温。当然，在能够对上 述管路中的冷却液进行降温的前提下，所述换热器可以采用任何适当的形式，而不仅限于压缩机***。
本领域技术人员能够理解的是，所述电池温度调节***与多个电池相连，每个温度传感器与每个电池一一对应地设置在一个分支管路上，电池控制模块和水路控制采用并联方式，当需要扩充或者减少引出的水路时(在***能力允许的前提下)，只需将接头进行扩展，同时从控制器中引出相应的传感器信号进行测量即可，可以灵活地针对不通应用场合进行扩展和缩减。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
