The control system of a new energy vehicle includes the battery control unit, motor control unit, and vehicle control unit, responsible for the detection and control functions of each system. Some existing technologies integrate some of the vehicle's high-voltage modules and control modules into a controller. However, the types of high-voltage modules and control modules integrated in such controllers are limited, resulting in a low level of integration.

[0032] Reference below Figures 1-4 An integrated controller 100 for a vehicle according to an embodiment of the present invention is described.

[0033] like Figures 1-4 As shown, the integrated controller 100 for a vehicle according to the present invention includes: a shell and a first spacer 91, and an installation cavity is formed inside the shell; the first spacer 91 is arranged in the installation cavity and divides the installation cavity into a first cavity and a second cavity, the first cavity is suitable for arranging high-voltage electrical devices, and the second cavity is suitable for arranging low-voltage electrical devices; wherein the high-voltage electrical devices include at least a motor control unit 16, and the low-voltage electrical devices include at least a battery control unit 17. Specifically, the integrated controller 100 integrates high-voltage electrical devices and low-voltage electrical devices. In some embodiments, the integrated controller 100 integrates high-voltage power supply parts such as power batteries, high-voltage drive parts such as motors, high-voltage distribution parts such as DC power supply 14, AC power supply 15, power distribution, and high-voltage charging parts such as DC fast charging. It also integrates control parts such as battery control unit 17 and motor control unit 16, so that the overall physical integration of the integrated controller 100 is high, and the power connection between modules can be reduced, thereby improving space utilization and saving costs. In addition, the integrated controller 100 has less system loss and higher work efficiency. As a whole, the integrated controller 100 has a high degree of standardization and modularization, which can improve product consistency and production efficiency and reduce failure rate.

[0034] In addition, in order to enable the integrated controller 100 to work normally, the layout principles of the internal structures of the integrated controller 100 must follow the separation of high and low voltage, separation of the control part and the power part, reduction of copper busbar 19 crossing, and reasonable layout for convenient installation and maintenance. For example, multiple modules inside the integrated controller 100 can be arranged in the first cavity and the second cavity respectively, wherein the first cavity can be used to arrange high-voltage electrical devices such as high-voltage distribution components and motor control units 16, and the second cavity can be used to arrange low-voltage electrical devices such as fuses 11 and battery control units 17. In order to reduce the interference between high-voltage electrical devices and low-voltage electrical devices, the high-voltage electrical devices and the low-voltage electrical devices need to be isolated by a first spacer 91 to ensure that the high-voltage electrical devices and the low-voltage electrical devices can work normally.

[0035] According to the utility model, the integrated controller 100 for a vehicle can integrate high-voltage electrical devices such as a motor control power supply and low-voltage electrical devices such as a battery control unit 17 of the vehicle. It has a higher degree of integration, a more compact space, a higher space utilization rate, and is convenient for assembly and maintenance.
