[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] A thermal management high-voltage integrated controller and a vehicle according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0036] Figure 1 4 is a structural block diagram of a thermal management high-voltage integrated controller according to an embodiment of the present invention.

[0037] like Figure 1As shown, the thermal management high-voltage integrated controller 100 includes: a branching module 110 and a control module 120. The branching module 110 includes a high-voltage input interface 111, a first high-voltage branching interface 112 and a second high-voltage branching interface 113. The high-voltage input interface 111 is used to connect to the high-voltage bus of the vehicle, and is connected to the first high-voltage branching interface 112 and the second high-voltage branching interface 113 respectively, wherein the first high-voltage branching interface 112 is used to connect to the first high-voltage component of the vehicle (such as the front electric drive, high-voltage fan, etc. arranged at the front of the vehicle). The control module 120 includes a power supply interface 121, a high-voltage control area 122, a thermal management high-voltage interface 123, a low-voltage control area 124 and a low-voltage interface 125. The high-voltage control area 122 is connected to the second high-voltage branch line interface 113 and to the thermal management high-voltage interface 123 through the power supply interface 121. The low-voltage control area 124 is used to connect to an external low-voltage power supply (such as a low-voltage battery of the vehicle) through the low-voltage interface 125, and is connected to the high-voltage control area 122 to control the high-voltage control area 122 to drive the second high-voltage component connected to the thermal management high-voltage interface 123 to work. The second high-voltage component includes the vehicle's thermal management high-voltage components, such as a compressor and a heater arranged at the front of the vehicle.

[0038] Among them, the first high-voltage component and the second high-voltage component can be arranged at the same predetermined position of the vehicle, and the predetermined position can be the front, chassis or rear of the vehicle. The number of the first high-voltage branch line interface 112 can be one or more, and the number can be configured according to the specific requirements of the high-voltage component. For example, if the number is greater than or equal to two, one interface can be connected to the front electric drive to match the vehicle with the front motor requirement, and one interface can be connected to the high-voltage fan to match the vehicle with the high-power fan requirement. The connection form and the number of interfaces of the thermal management high-voltage interface 123 can be diversified according to actual needs. For example, if the number is greater than or equal to two, two compressors can be connected to meet the system requirements of dual compressors, and two heaters can be connected to meet the requirements of high and low temperature water circuit dual heaters, or a combination of water heaters and air heaters.

[0039] Specifically, the thermal management high-voltage integrated controller 100 of the embodiment of the present invention can be set at the front of the vehicle, such as in the front cabin, and connected to the high-voltage line drawn from the power battery of the vehicle through the high-voltage input interface 111 in the branching module 110, and the high-voltage control area 122 in the control module 120 is powered through the second high-voltage branching interface 113 in the branching module 110 to control the operation of the thermal management high-voltage components (such as compressors and heaters) connected to the thermal management high-voltage interface 123, which can simplify the high-voltage connection of the thermal management high-voltage components and make the overall high-voltage wiring of the thermal management simpler. In addition, when the number of thermal management high-voltage interfaces 123 is multiple, the controllers of traditional thermal management high-voltage components such as compressors and heaters can be integrated, reducing the number of electronic components. At the same time, the compressor and heater without the mechanical part of the controller can achieve more flexible spatial layout.

[0040] At the same time, by setting the first high-voltage branch interface 112 (the number can be one or more) in the branch module 110, the connection requirements of other high-voltage components in the vehicle except the thermal management high-voltage components (that is, the first high-voltage components, such as electric front drive, high-voltage fan, etc.) can be met, so that the integrated functions of the entire controller are richer and the application is wider, and the length and number of high-voltage wire harnesses from the rear end to the front of the vehicle can be greatly reduced, thereby greatly reducing costs.

[0041] In some embodiments of the present invention, Figure 2 As shown, the high voltage control area 122 is provided with a power unit 1221 , a drive unit 1222 , a bus voltage detection unit 1223 and a bus current detection unit 1224 .

[0042] See also Figure 2 The input end of the power unit 1221 is connected to the power supply interface 121, the output end of the power unit 1221 is connected to the thermal management high-voltage interface 123, and the control end of the power unit 1221 is connected to the drive unit 1222; the drive unit 1222 is connected to the low-voltage control area 124; the bus voltage detection unit 1223 and the bus current detection unit 1224 are connected to the power supply interface 121 to collect the bus voltage and bus current, and are connected to the low-voltage control area 124 to send the bus voltage and bus current data to the low-voltage control area 124.

[0043] Among them, the power unit 1221 can be composed of a power device IGBT, and the drive unit 1222 is used to control the on and off of the power device IGBT in the power unit 1221 to realize the circuit control of the thermal management high-voltage device, such as a compressor and a heater, connected to the thermal management high-voltage interface 123. The bus voltage detection unit 1223 and the bus current detection unit 1224 are mainly used to monitor the voltage and current input to the control module 120 after the second high-voltage branch interface 113, so that the low-voltage control area 124 can perform related control according to the voltage and current, such as overvoltage, undervoltage, overcurrent protection, etc.

[0044] In some embodiments of the present invention, Figure 3 As shown, the low voltage control area 124 is provided with a control unit 1241 , a communication unit 1242 , and a power supply conversion unit 1243 .

[0045] See also Figure 3 The control unit 1241 is connected to the drive unit 1222, the bus voltage detection unit 1223, the bus current detection unit 1224, the communication unit 1242, and the power conversion unit 1243 respectively; the communication unit 1242 is used to connect to the communication line of the vehicle, such as the controller area network (CAN) communication line, the local interconnect network (LIN) communication line, etc., to establish a connection between the control unit 1241 and the communication line of the vehicle; the power conversion unit 1243 is connected to the low voltage interface 125 and the drive unit 1222 respectively, and is used to convert the low voltage electricity provided by the external low voltage power supply, and supply the converted voltage to the control unit 1241 and the drive unit 1222.

[0046] Specifically, the control unit 1241 may adopt a microcontroller unit (MCU), which is mainly used to control the drive unit 1222, exchange signals with the communication unit 1242, receive and perform corresponding control according to the bus voltage and bus current, etc.; the power supply conversion unit 1243 accepts the input of an external low-voltage power supply (such as a 24V or 12V power supply) and performs voltage conversion, such as converting AC to DC, or converting a DC voltage value, to power the control unit 1241 and the drive unit 1222. It should be noted that the low-voltage interface 125 can not only be connected to an external low-voltage power supply through a low-voltage power supply harness for the input of a low-voltage power supply, but also establish a connection between the communication unit 1242 and the vehicle communication line through a signal harness for the input of interactive signals.

[0047] In some embodiments of the present invention, Figure 4As shown, the low voltage control area 124 is further provided with a voltage stabilizing unit 1244 , which is connected between the power supply conversion unit 1243 and the control unit 1241 , and is used for stabilizing the voltage converted by the power supply conversion unit 1243 .

[0048] The voltage stabilizing unit 1244 may adopt a low dropout regulator (LDO), and the power supply conversion unit 1243 receives the input of an external low voltage power supply and converts it into a voltage required by the control unit 1241 through the LDO.

[0049] In some embodiments of the present invention, Figure 5 As shown, the low-pressure control area 124 is also provided with a sensor input unit 1245 , which is connected to the control unit 1241 and is used to send detected data, such as temperature information of the thermal management high-pressure integrated controller 100 , to the control unit 1241 .

[0050] Specifically, the electrical components in the thermal management high-voltage integrated controller 100 can be arranged on a printed circuit board (PCB), and the sensor input unit 1245 can detect the temperature signal of the PCB board itself and input it to the control unit 1241 so that the control unit 1241 can perform over-temperature protection.

[0051] In some embodiments of the present invention, Figure 6 As shown, a high-voltage fuse element 114 is provided on the connection line between the first high-voltage branch line interface 112 , the second high-voltage branch line interface 113 and the high-voltage input interface 111 .

[0052] The high-voltage fuse element 114 may be a fuse, which is used to improve the reliability of the high-voltage power supply of the branching module 110. Figure 6 The high-voltage fuse element 114 can be arranged on the positive connection line between the high-voltage input interface 111 and each high-voltage branch interface.

[0053] In some embodiments of the present invention, Figure 7 As shown, the control module 120 further includes an isolation device 126 for isolating the high-voltage control area 122 from the low-voltage control area 124 .

[0054] Among them, the isolation device 126 can be used to achieve isolation of the power supply circuits of the high-voltage control area 122 and the low-voltage control area 124, and can also achieve isolation of communication signals between the high-voltage control area 122 and the low-voltage control area 124, and the specific form is not limited.

Figure 7 The branching module 110 and other components in the control module 120 may be disposed in the housing 130 to facilitate installation in the vehicle.

[0056] Specifically, see Figure 8 For the convenience of identification and connection, the high-voltage input interface 111, the first high-voltage branch interface 112, the thermal management high-voltage interface 123 and the low-voltage interface 125 provided on the housing 130 can be of different sizes and can be provided at different positions. Figure 8 The cube shown in can also be a cylinder, a special-shaped structure, etc., depending on the layout requirements. The arrangement structure and number of interfaces of the input and output terminals can also be flexibly adapted according to different requirements and structures, and the layout of the entire circuit inside the shell 130 can be designed according to the specific spatial structure and interface position. The thermal management high-voltage integrated controller 100 can be arranged separately on the crossbeam, subframe or body at the front of the vehicle, or it can be integrated into the mechanical structure of the compressor or heater. Among them, the thermal management high-voltage integrated controller 100 is physically decoupled from high-voltage components such as compressors and heaters, which can achieve more flexible layout and combination.

[0057] In addition, it should be noted that Figure 1-Figure 7 The electrical principle diagram of the thermal management high-voltage integrated controller 100 is shown. The specific physical structure is not limited and can be distributed left and right, arranged in layers up and down, or arranged in a special-shaped structure. The connection lines between the high-voltage input interface 111 and the first high-voltage branch interface 112 and the second high-voltage branch interface 113 in the branch module 110 can be arranged according to the actual physical space, and the connection lines can be copper wires.

Of course, for the convenience of wiring, the thermal management high-voltage integrated controller 100 can also be arranged at the front of the vehicle 200.

[0060] Optionally, the first high voltage component 210 and the second high voltage component 220 may also be arranged on a chassis, a rear portion, etc. of the vehicle 200 .
