在一些实施例中，所述上箱体100至少设有两个所述电池包接口905和两个所述充电枪接口906。在附图所给的实施例中，所述的电池包接口905和充电枪接口906的数量均为两个。由于电池包接口905为双路，可实现单电池包或者双电池包运行；由于充电枪接口906为双路，可实现双直流充电、双交流充电、交直流充电、单枪直流充电、单枪交流充电等多种充电方式。
如图1、图2和图4所示，所述电池包接口905与所述高压配电模块900的连接线路上、以及所述充电枪接口906与所述高压配电模块900的连接线路上均设有磁环903和Y电容904。通过在充放电输入接口采用磁环903加Y电容904设计，可以节约空间，改善EMC(Electro Magnetic Compatibility；电磁兼容性)。
如图1、图2和图4所示，所述上箱体100内还设有连接于所述高压配电模块900的漏电传感器902，所述上箱体100设有对应于所述漏电传感器902的输入输出接口，该输入输 出接口连接于BMS。通过设置漏电传感器902，不仅能在所述箱体10内的控制器漏电时提供监测保护，同时还提供了充电接触器烧结检测的保护功能。
如图1、图2和图4所示，所述上箱体100内还设有连接于所述高压配电模块900的光耦烧结检测器901，所述上箱体100设有对应于所述光耦烧结检测器901的输入输出接口，该输入输出接口连接于BMS。通过设置光耦烧结检测器901，可以实现所述集成控制器A中所有接触器的烧结检测功能。
如图6至图13所示，上箱体100与下箱体200连接，上箱体100和下箱体200之间设置有相互独立的第一冷却水道A1和第二冷却水道A2，右驱动电机控制器400、空压机控制器500和转向电机控制器600通过第一冷却水道A1散热，左驱动电机控制器300和DC-DC电压转换器700通过第二冷却水道A2散热。
在本公开提供的集成控制器A中，设置相互独立的两条冷却水道以对集成控制器A上的不同模块进行散热。相较于现有技术中单水道的设置方式，采用双水道冷却至少具有以下三个优势：第一，在待冷却模块数量不变的情况下，每条水道中冷却液冷却的模块数量得以减少，一定程度上避免出现因冷却液温度较高失去冷却作用的情况，保证了对每一个待冷却模块的有效冷却；第二，每条水道的循环路径缩短，降低了冷却液流动过程中的压损，从而降低了对水泵的要求，即，允许采用压力、流量相对较小的水泵。另外，循环路径缩短亦可缩短高温冷却液在集成控制器A内部循环的时间，避免造成整个集成控制器A温度的升高；第三，每条水道流经面积减小，循环路径缩短，使得水道密封的难度降低，从而降低了水道漏水的风险。
其中，上箱体100和下箱体200可以形成为任意适当的结构和形状。在一种实施方式中，如图6所示，上箱体100包括上箱体底壁101和形成在上箱体底壁101四周的上箱体侧壁102，上箱体底壁101的下表面上形成有相互独立的第一冷却水槽103和第二冷却水槽104，下箱体200包括下箱体顶壁201和形成在下箱体顶壁201四周的下箱体侧壁202。下箱体顶壁201的上表面上形成有相互独立的第三冷却水槽203和第四冷却水槽204，上箱体底壁101的下表面与下箱体顶壁201的上表面贴合，以使第一冷却水槽103和第四冷却水槽204共同限定出第一冷却水道A1、第二冷却水槽104和第三冷却水槽203共同限定出第二冷却水道A2。
在本实施方式中，充分利用上箱体底壁101和下箱体顶壁201结构，通过在箱体底壁101和下箱体顶壁201上开设水槽的方式，限定出相互独立的第一冷却水道A1和第二冷却水道A2，避免了在箱体上单独加工冷却水道，节约空间，便于集成控制器A中其他零部件 的布置。在其他可替代的实施方式中，第一冷却水道A1和第二冷却水道A2可单独设置在上箱体底壁101或下箱体顶壁201上；或者，第一冷却水道A1和第二冷却水道A2中的一者可单独形成在上箱体底壁101上，另一者可单独形成在下箱体顶壁201上；再或者，可单独设置两条独立的水管，两条水管通过紧固件固定在集成控制器A的箱体上，两条水管的内部分别限定出第一冷却水道A1和第二冷却水道A2。
其中，为了实现上箱体100和下箱体200的可靠连接并提升第一冷却水道A1和第二冷却水道A2的密封性，在一种实施方式中，上箱体100与下箱体200通过螺栓连接且通过摩擦焊连接。
在本公开中，左驱动电机控制器300和右驱动电机控制器400中的待冷却元件主要为IGBT(绝缘栅双极型晶体管)模块，空压机控制器500和转向电机控制器600中待冷却元件为IPM(智能功率模块)。其中IGBT模块通常采用直接与冷却液接触的方式散热，空压机控制器500的IPM 501和转向电机控制器600的IPM 601通常采用与冷却管道管壁接触的方式散热。因此，在本公开的一种实施方式中，安装时，空压机控制器500、转向电机控制器600和DC-DC电压转换器700可与下箱体顶壁201接触，这样，当冷却液流在下箱体顶壁201上流动时，上述三个模块可通过下箱体顶壁201与冷却液进行热交换，以到达散热冷却的目的。
此外，如图6、图7、图11和图13所示，上箱体底壁101上形成有贯穿上箱体底壁101的两个开口105，左驱动电机控制器300设置在一个开口105上，以使左驱动电机控制器300的散热柱(IGBT模块的散热柱801)与第二冷却水道A2中的冷却液接触；右驱动电机控制器400设置在另一个开口105上，以使右驱动电机控制器400的散热柱与第一冷却水道A1中的冷却液接触。
如图6和图7所示，开口105内可以形成有加强筋106，加强筋106的两端与开口105的一对侧边相连，加强筋106与冷却液的流向垂直。
如图6和图8所示，下箱体顶壁201的上表面上与开口105对应的位置形成有凸台205，凸台205与开口105的形状适配，凸台205上形成有避让加强筋106的避让槽206。这样，在将上箱体底壁101和下箱体顶壁201贴合之后，凸台205插入到开口105中，加强筋106插入到避让槽206中并且加强筋106的上表面与凸台205的上表面齐平。此时，IGBT模块的散热柱801放置在凸台205上，冷却液在多个散热柱801的缝隙之间流动，从而实现热交换。
这里，通过设置加强筋106，一方面能够提升上箱体底壁101的结构强度，以满足对左 驱动电机控制器300和右驱动电机控制器400等零部件安装的强度需求，另一方面，由于加强筋106垂直于冷却液的流向，起到了对下层冷却液的阻绝作用，这样就增大了凸台205的宽度尺寸小于开口105的宽度尺寸的允许量，换句话说，如果没有加强筋106，为了避免冷却液从凸台205的左右侧壁与开口105的左右侧壁的缝隙中快速流过而减弱冷却液对IGBT模块的冷却效果，通常尽可能地增大凸台205的宽度尺寸，以减小上述缝隙。在本公开中，由于加强筋106的存在，即便凸台205的宽度尺寸比开口105的宽度尺寸小很多，冷却液也不会从凸台205的左右侧壁与开口105的左右侧壁的缝隙中流过，从而能够提升冷却液对IGBT模块的冷却效果。
为了能够最大程度实现待冷却件的冷却，提高冷却效率，在本公开的一种实施方式中，第一冷却水道A1中的冷却液可先冷却转向电机控制器600，再冷却空压机控制器500和右驱动电机控制器400，即，使得冷却液先对发热量相对较低的转向电机控制器600进行冷却，最后冷却发热量高的右驱动电机控制器400，这样的好处在于，冷却液在流经转向电机控制器600后温度不会有大幅升高，之后在流经空压机控制器500和右驱动电机控制器400的过程中仍然能够起到有效冷却作用。同样地，第二冷却水道A2中的冷却液先冷却发热量较低的DC-DC电压转换器700，再冷却发热量较高的左驱动电机控制器300。
在本公开中，第一冷却水道A1和第二冷却水道A2的截面形状以及在集成控制器A的箱体上的位置可以根据周围零部件的结构和位置进行灵活布置，本公开对此不作限制。在一种实施方式中，为了便于加工，第一冷却水道A1和第二冷却水道A2的横截面可以呈矩形，为了便于布置其他零部件，第一冷却水道A1和第二冷却水道A2可对称设置在上箱体100与下箱体200之间的贴合面上。
还需要说明的是，由于在本公开提供的集成控制器A中，通过在箱体10内集成左驱动电机控制器300、右驱动电机控制器400、空压电机控制器500、转向电机控制器600和DC-DC电压转换器700以及高压配电模块900，使得所述高压配电模块900中的易损件如出充电保险、主保险、配电小保险和预充电阻可在整车上实现更换，无需将集成控制器A返回厂商替换，进一步节约了成本。
结合图14，本公开还提供一种车辆B，所述车辆B包括上述的集成控制器A。在一些实施例中，该车辆B还包括第一水泵B1和第二水泵B2，第一水泵B1用于驱动第一冷却水道A1中的冷却液循环，第二水泵B2用于驱动第二冷却水道A2中的冷却液循环。相较于只设置单个水泵的方式，通过设置两个独立水泵能够避免出现因单个水泵故障引起集成控制器A冷却失效的情况，提升了整车正常运行的可靠性。
以上结合附图详细描述了本公开的优选实施方式，但是，本公开并不限于上述实施方式中的具体细节，在本公开的技术构思范围内，可以对本公开的技术方案进行多种简单变型，这些简单变型均属于本公开的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合。为了避免不必要的重复，本公开对各种可能的组合方式不再另行说明。
此外，本公开的各种不同的实施方式之间也可以进行任意组合，只要其不违背本公开的思想，其同样应当视为本公开所公开的内容。
