In this embodiment, the power supply voltage of the vehicle thermal management system is designed to be consistent with the power supply voltage of the vehicle low-voltage power distribution system, thereby integrating the vehicle low-voltage power distribution system and the vehicle thermal management system. The control and management of the vehicle low-voltage power distribution system and the thermal management system are realized by the same controller 120. By integrating the functions of managing the low-voltage battery 300 and the thermal management load and the function of power distribution control of the low-voltage load in the controller 120, not only the communication wiring harnesses set between the independent low-voltage power distribution system and the independent thermal management system are reduced, but also there is no need to set up an independent controller and related SBC power supply chips, thereby saving the number of chips used and reducing the probability of failure of the power supply and communication wiring harnesses in the vehicle low-voltage power distribution system.

[0109] In this embodiment, the controller 120 integrates the functions of managing the low-voltage battery 300 and the thermal management load and the function of controlling the power distribution of the low-voltage load. After the vehicle is started, the controller 120 can manage the energy output of the low-voltage power distribution system of the vehicle based on the thermal management feedback information of the vehicle, and can also manage the working state of the thermal management load based on the energy output of the low-voltage power distribution system of the vehicle, so that the vehicle's low-voltage power distribution system and the vehicle thermal management system are adapted to each other based on the current vehicle condition, thereby improving the power utilization efficiency and power supply stability of the low-voltage power distribution system of the vehicle.

[0110] In some specific application embodiments, since the controller 120 and a part of the power devices are used to form the battery management module 100, the controller 120 and another part of the power devices are used to form the low-voltage power distribution module 200, and the controller 120 and the thermal management drive unit are used to form the thermal management module 900, there is no need for a large fuse box, and the battery management module 100, the low-voltage power distribution module 200, the thermal management module 900 and the low-voltage battery 300 can be further integrated into the low-voltage battery assembly, which not only reduces the volume of the vehicle's low-voltage power distribution system and the vehicle's thermal management system, but also shortens the wiring harness distance between the low-voltage battery 300 and the battery management module 100, shortens the wiring harness distance between the low-voltage battery 300 and the low-voltage power distribution module 200, and shortens the wiring harness distance between the vehicle's low-voltage power distribution system and the thermal management system, thereby reducing the probability of failure of the power supply and communication wiring harnesses in the vehicle's low-voltage power distribution system and the thermal management system.

[0111] In some embodiments, see Figure 2 As shown, the vehicle integrated domain controller architecture in this embodiment also includes a low-voltage power input terminal 400, which is electrically connected to the low-voltage power distribution module 200. The low-voltage power input terminal 400 can be used to access the low-voltage power converted by the power battery, and the low-voltage power distribution module 200 distributes power to the input low-voltage power.

[0112] In this embodiment, the low-voltage power supply input terminal 400 is used to access the low-voltage power supply obtained by voltage conversion from the power battery, and the low-voltage power distribution module 200 distributes the low-voltage power supply to the low-voltage load access terminal 210. For example, in the case of multiple low-voltage load access terminals 210, power distribution is performed according to the power demand of the low-voltage load connected to each low-voltage load access terminal 210, and power distribution can also be performed according to the working status of the connected low-voltage load, thereby realizing dynamic adjustment of the output power of the low-voltage power supply and achieving the purpose of protecting the low-voltage battery 300 and the low-voltage load.

There is no need to set a power distribution management device in the low-voltage power distribution module 200, and the wiring harness between the low-voltage power distribution module 200 and the battery management module 100 is reduced, thereby reducing the problem of safety hazards caused by short circuits in the wiring harnesses between different circuit boards.

[0115] In some specific application embodiments, the first switch module 101 and the controller 120 constitute a battery management module 100, and the low-voltage battery 300 is connected to the low-voltage power distribution module 200 via the first switch module 101. By connecting the low-voltage battery 300 and the low-voltage power distribution module 200 through the first switch module 101, not only can the low-voltage power distribution module 200 reuse the first switch module 101 to regulate and manage the current input to the low-voltage power distribution module 200, but also the low-voltage battery 300 can be short-circuited to reduce safety hazards caused by failures of the low-voltage battery 300.

The controller 120 controls the switching state of the first switch module 101 to control the switching state between the low-voltage battery 300 and the low-voltage power distribution module 200. The first switch module 101 controls the power distribution output of the low-voltage power distribution module 200, so that the low-voltage power distribution module 200 and the battery management module 100 can reuse the first switch module 101, thereby reducing the wiring harness between the low-voltage power distribution module 200 and the battery management module 100, and reducing the problem of safety hazards caused by short circuits in the wiring harnesses between different circuit boards.

The bidirectional switch device is controlled by the controller 120, and can control the charging and discharging of the low-voltage battery 300. The second end of the third switch module 203 is connected to the low-voltage battery 300 through the first switch module 101. When the first switch module 101 is in the first conduction condition, the low-voltage battery 300 supplies power to the first low-voltage load access 211 or the second low-voltage load access end 212 through the first switch module 101, and at this time, the low-voltage power input end 400 cannot charge the low-voltage battery 300.

[0159] In this embodiment, the low-voltage power distribution module 200 can perform power distribution management on multiple thermal management drive units according to the power distribution instructions sent by the controller. Multiple thermal management loads are directly connected to the output end of the thermal management module 900. Each thermal management drive unit controls the state of the corresponding thermal management load according to the thermal management control instructions sent by the controller 120, thereby realizing direct drive thermal management control of the vehicle.

[0160] In some embodiments, the low-voltage power distribution module 200 may include multiple power devices, which form a switching circuit.

[0161] In some embodiments, a plurality of thermal management driving units may be connected to one or more of the low-voltage load access terminals 210 , and the low-voltage load access terminals 210 may supply power to the thermal management driving units.

[0162] In one embodiment, when the thermal management module 900 draws power through the low-voltage power input terminal 400, the thermal management module 900 also includes a thermal management power distribution unit, which is connected to the battery management module 100. The thermal management power distribution unit performs power distribution management on multiple thermal management drive units according to the power distribution instructions sent by the controller.

[0163] In this embodiment, the thermal management distribution unit can perform power distribution management on multiple thermal management drive units according to the power distribution instructions sent by the controller 120. The load access terminal 210 can connect to multiple thermal management loads. Each thermal management drive unit controls the state of the corresponding thermal management load according to the thermal management control instructions sent by the controller 120, thereby realizing direct drive thermal management control of the vehicle.

[0164] In some embodiments, the thermal management power distribution unit may be a switch component such as a relay or a fuse box.

[0165] In some embodiments, multiple thermal management drive units include at least one of a motor water pump control unit, a battery water pump control unit, an air conditioning water pump control unit, a fan control unit, a water valve control unit, an air intake grille control unit, an expansion valve control unit, a stop valve control unit, a stepper motor control unit, and a blower control unit.

[0166] Specifically, the motor water pump control unit is controlled by the controller 120, and the motor water pump control unit is used to control and drive the motor water pump; the battery water pump control unit is controlled by the controller 120, and the battery water pump control unit is used to control and drive the battery water pump; the air conditioning water pump control unit is controlled by the controller 120, and the air conditioning water pump control unit is used to control and drive the air conditioning water pump; the fan control unit is controlled by the controller 120, and the fan control unit is used to control and drive the electronic fan; the water valve control unit is controlled by the controller 120, and the water valve control unit is used to control and drive the water valve; the air intake grille control unit is controlled by the controller 120, and the air intake grille control unit is used to control and drive the active air intake grille; the expansion valve control unit is controlled by the controller 120, and the expansion valve control unit is used to control and drive the expansion valve; the stop valve control unit is controlled by the controller 120, and the stop valve control unit is used to control and drive the stop valve; the stepping motor control unit is controlled by the controller 120, and the stepping motor control unit is used to control and drive the single and bipolar stepping motor damper; the blower control unit is controlled by the controller 120, and the blower control unit is used to control and drive the blower.

[0168] In some embodiments, the motor water pump control unit, the battery water pump control unit, the air conditioning water pump control unit, the fan control unit, the water valve control unit, the air intake grille control unit, the expansion valve control unit, the stop valve control unit, the stepper motor control unit, and the blower control unit can be switching devices, or they can be full-bridge drive circuits or half-bridge drive circuits.

[0169] The full-bridge drive circuit can also be called an H-bridge drive circuit. It has a total of four switch arms, which can be MOS tubes or triodes. The four switch arms are controlled by the controller 120. The controller 120 provides corresponding drive control signals to control the switching states of the four switch arms, thereby controlling the drive current output by the full-bridge drive circuit and achieving the purpose of managing the thermal management load connected to the full-bridge drive circuit.

[0170] In the field of power electronics, the full-bridge drive circuit controls the conduction and cutoff of four switch tubes (such as MOS tubes, triodes, etc.) to realize the forced conversion of the motor frequency and direction. Its control signal can realize PWM modulation to achieve different speeds and steering control of the motor. The half-bridge drive controls the conduction and cutoff of two switch tubes to realize the speed and steering control of the motor. The control signal can also realize PWM modulation. The half-bridge drive is suitable for low-power motor drives, such as electronic fans.

[0171] Half-bridge gate drivers are widely used in various power control applications such as AC drives, DC to DC converters, etc. Full-bridge drivers and half-bridge drivers are circuits used to control motors or other loads. They use MOSFET tubes as switches to control the current of thermal management loads.

[0172] In some embodiments, when there is only one low-voltage load access terminal 210, the thermal management load and the low-voltage load can be connected to the same low-voltage load access terminal 210, and the working state of the low-voltage load is controlled by the low-voltage power distribution module 200, and the working state of the thermal management load is controlled by the thermal management module 900, so as to realize the simultaneous management and control of the low-voltage load and the thermal management load by the controller 120.

[0174] In this embodiment, since the battery management module 100, the low-voltage power distribution module 200 and the thermal management module 900 share the same controller 120, the controller 120 and the thermal management drive unit constitute the thermal management module 900. Therefore, when the controller 120 is integrated into the first circuit board 123, the thermal management drive unit is integrated into the second circuit board 124 and connected to the controller 120 on the first circuit board 123 through a wiring harness. The controller 120 sends a thermal drive control signal to the thermal management drive unit to perform the function of thermal management load management, which can reduce the packet loss caused by data communication between circuit boards. The battery management module 100 composed of the controller 120 and some of its peripheral driving devices manages the status of the low-voltage battery, and the low-voltage power distribution module 200 composed of the controller 120 and another part of its peripheral driving devices controls the power distribution of the load connected to the low-voltage load access terminal 210. The low-voltage power distribution module 200 and the battery management module 100 are integrated on the first circuit board 123, and the controller 120 is also integrated on the first circuit board 123. This can avoid the problem that the original battery management module 100 and the low-voltage power distribution module 200 are independently set, resulting in a large number of wiring harnesses required to connect the circuit boards, and reduce the probability of wiring harness failure by simplifying the lines.

[0175] In some embodiments, the external pins of the controller 120 can not only form a low-voltage power distribution module 200 and a battery management module 100 with the driving device on the first circuit board 123, but can also form a thermal management module 900 with the thermal management driving unit on the second circuit board 124, thereby achieving the effect of expanding the driving scheme.

[0176] In some embodiments, see Figure 8 As shown, the vehicle integrated domain controller architecture includes a first circuit board 123 and a second circuit board 124 , the low-voltage power distribution module 200 and the battery management module 100 are integrated on the first circuit board 123 , the thermal management module 900 is integrated on the second circuit board 124 , and the controller 120 is also integrated on the second circuit board 124 .

[0177] In this embodiment, since the battery management module 100, the low-voltage power distribution module 200 and the thermal management module 900 share the same controller 120, the controller 120 and the thermal management drive unit constitute the thermal management module 900, and the controller 120 and other drive devices constitute the battery management module 100 and the low-voltage power distribution module 200. Therefore, when the controller 120 is integrated on the second circuit board 124 and other drive devices are integrated on the first circuit board 123, the other drive devices are connected to the controller 120 on the second circuit board 124 through a wiring harness, and the controller 120 sends corresponding drive control signals to other drive devices to perform related battery management and low-voltage power distribution management functions. Through the design in this embodiment, the packet loss caused by data communication between circuit boards can be reduced.

[0178] In some embodiments, a battery management module 100 composed of a controller 120 and a part of the driving devices on the first circuit board 123 manages the status of the low-voltage battery, and a low-voltage power distribution module 200 composed of the controller 120 and another part of the driving devices on the first circuit board 123 controls the power distribution of the load connected to the low-voltage load access terminal 210. The driving devices in the low-voltage power distribution module 200 and the battery management module 100 are integrated on the first circuit board 123, and the controller 120 and the thermal management drive unit are integrated on the second circuit board 124. This can not only improve the heat dissipation efficiency of the driving devices, but also avoid the problem that the original battery management module 100, the low-voltage power distribution module 200, and the thermal management module 900 are independently set, resulting in a large number of wiring harnesses required for signal transmission and data communication between the circuit boards. By simplifying the lines, the probability of wiring harness failure and data packet loss is reduced.

[0179] In some embodiments, the external pins of the controller 120 can not only form a low-voltage power distribution module 200 and a battery management module 100 with the driving device on the first circuit board 123, but also form a thermal management module 900 with the thermal management driving unit on the second circuit board 124, thereby achieving the effect of expanding the driving scheme.

[0180] In some embodiments, the controller 120 can also expand its external pins. For example, by soldering its external expansion pins to the expansion circuit on the first circuit board 123 and connecting the expansion circuit on the first circuit board 123 through multiple pads, the external expansion pins of the controller 120 can be functionally customized and reused to achieve the purpose of vehicle function customization.

[0181] In some embodiments, see Fig. 9 As shown, the vehicle integrated domain controller architecture also includes a vehicle heat sink 310, the first circuit board 123 is arranged on the first side of the vehicle heat sink 310, and the second circuit board 124 is arranged on the second side of the vehicle heat sink 310, the second side of the vehicle heat sink 310 is opposite to the first side of the vehicle heat sink 310, and the vehicle heat sink 310 is used to dissipate heat for the first circuit board 123 and the second circuit board 124.

[0182] In this embodiment, the first circuit board 123 and the second circuit board 124 are respectively arranged on both sides of the same vehicle heat sink 310. By sharing the same vehicle heat sink 310, the heat dissipation efficiency inside the vehicle can be improved and the volume of the vehicle can be reduced.

[0183] In some embodiments, see Fig.10As shown, the low-voltage battery 300 is disposed on the second side of the vehicle radiator 310 , and the second circuit board 124 is disposed between the low-voltage battery 300 and the vehicle radiator 310 to dissipate heat together with the low-voltage battery 300 .

[0184] In this embodiment, a thermal management drive unit is provided on the second circuit board 124. By setting the second circuit board 124 between the low-voltage battery 300 and the vehicle heat sink 310, not only the wiring harness length between the thermal management drive unit and the low-voltage drive device can be reduced, but also the temperature of the low-voltage battery 300 can be managed by integrating the relevant thermal management drive unit on the second circuit board 124, thereby reducing the signal transmission distance and reducing the size of the vehicle.

[0185] In some embodiments, see Fig.10 As shown, the low-voltage battery 300 is arranged in the product lower cover 125, and the product lower cover 125 is a concave structure. The product lower cover 125 and the product upper cover 126 form a storage cavity, and the first circuit board 123, the vehicle heat sink 310, and the second circuit board 124 are stacked on the low-voltage battery 300. The first circuit board 123, the vehicle heat sink 310, and the second circuit board 124 are fixed by an installation structure, wherein the distance between the first circuit board 123, the vehicle heat sink 310, the second circuit board 124 and the low-voltage battery 300 can be set according to the heat dissipation requirements and wiring harness requirements.

[0186] In some embodiments, the vehicle heat sink 310 can be a water-cooled plate, which is arranged between the first circuit board 123 and the second circuit board 124. After the car is started, the water-cooled plate absorbs the heat emitted by the first circuit board 123 and the second circuit board 124, thereby improving the space utilization efficiency inside the vehicle and reducing the size and volume of the vehicle's power distribution system.

[0187] In some embodiments, the controller 120 has at least two cores.

[0188] In this embodiment, the controller 120 has at least two cores, and multiple functions of the controller 120 can be distributed to the multiple cores to improve the processing efficiency of the controller 120.

[0189] In some embodiments, at least one core of the controller 120 is used to process the sampling signal of the low-voltage battery 300 to obtain sampling data, and at least one core of the controller 120 is used to generate control data based on the sampling data, and output a corresponding control signal based on the control data to control the working state of the low-voltage battery 300.

[0190] In this embodiment, the controller 120 includes at least two cores, one or part of the cores can be used to process the sampling signal to obtain corresponding sampling data, and the other core or another part of the cores can be used to process the sampling data, obtain control data according to preset operations, and generate a control signal based on the control data and output it to the peripheral driving device, so as to control the working state of the low-voltage battery 300 by controlling the working state of the driving device.

[0191] In some embodiments, at least one core of the controller 120 is used to process the sampling signal of the low-voltage load to obtain sampling data, and at least one core of the controller 120 is used to generate control data based on the sampling data, and output a corresponding control signal based on the control data to control the distribution power of the low-voltage load.

[0192] In this embodiment, the controller 120 includes at least two cores, one or part of the cores can be used to process the sampling signal to obtain corresponding sampling data, and the other core or another part of the cores can be used to process the sampling data, obtain control data according to preset operations, and generate a control signal based on the control data and output it to the peripheral driving device, so as to control the distribution power of the low-voltage load by controlling the working state of the driving device.

[0193] In some embodiments, at least one core of the controller 120 is used to process the sampling signal of the thermal management module 900 to obtain sampling data, and at least one core of the controller 120 is used to generate control data based on the sampling data, and output a corresponding control signal based on the control data to control the distribution power of the low-voltage load.

[0194] In this embodiment, the controller 120 includes at least two cores, one or part of the cores can be used to process the sampling signal to obtain corresponding sampling data, and the other core or another part of the cores can be used to process the sampling data, obtain control data according to preset operations, and generate a control signal based on the control data and output it to the peripheral thermal management drive unit, so as to control the working state of the thermal management load by controlling the working state of the thermal management drive unit.

[0195] In some embodiments, see Fig.11 As shown, the vehicle integrated domain controller architecture includes an SBC power supply module 510 , which is connected to the controller 120 , and is used to supply power to the controller 120 .

[0196] In this embodiment, the SBC power supply module 510 within the vehicle integrated domain controller architecture can be integrated into the battery management module 100 or the low-voltage power distribution module 200, or can be integrated into the thermal management module 900. The power source of the SBC power supply module 510 can be the low-voltage battery 300.

[0197] In some embodiments, the power input terminal of the SBC power supply module 510 is connected to the low voltage battery 300 and the low voltage power input terminal 400 respectively, and the power output terminal of the SBC power supply module 510 is connected to the controller 120 .

[0198] In this embodiment, the power input terminal of the SBC power supply module 510 can draw power from the low-voltage battery 300 or the low-voltage power input terminal 400 respectively. By converting the voltage input from the low-voltage battery 300 or the low-voltage power input terminal 400 into the power supply voltage of the controller 120, the purpose of powering the controller 120 is achieved, avoiding the problem of the controller 120 requiring an additional wiring harness to draw power from an external power supply.

[0199] In some embodiments, the power input end of the SBC power supply module 510 can be connected to the low-voltage battery 300 and the low-voltage power input end 400 at the same time. An anti-backflow circuit is set between the power input end of the SBC power supply module 510 and the low-voltage battery 300. An anti-backflow circuit is set between the power input end of the SBC power supply module 510 and the low-voltage power input end 400. This can prevent the current backflow generated when the low-voltage battery 300 and the low-voltage power input end 400 output current, thereby improving the safety of the power supply circuit.

[0200] The power management chip (System Base Chip, SBC) is the provider of the working voltage for the controller 120 and its peripheral devices. Without the SBC power supply, the peripheral devices of the controller cannot work. In this embodiment, the controller 120 and a part of the power devices form a battery management module 100, and the controller 120 and another part of the power devices form a low-voltage power distribution module 200. The controller 120 integrates the functions of managing the low-voltage battery 300 and the function of controlling the power distribution of the low-voltage load. Therefore, the SBC power supply module 510 outputs multiple voltages according to the input power supply, which can power the controller 120 and its peripheral power devices. Only one SBC chip is needed to power the components of the low-voltage power distribution system of the whole vehicle, which not only saves the SBC chip, but also optimizes the low voltage The power management solution of the power distribution system reduces the performance instability problem caused by inconsistent power supply voltage in the independent SBC solution, and improves the working consistency of power devices and chips in the low-voltage power distribution system. For example, the SBC power supply module 510 outputs a 3.3V independent power supply to power the controller 120, and can also output a 3.3V independent power supply to power the analog chip on the circuit board 123, and a 5V independent power supply to power the communication chip on the circuit board 123. The input power supply of the SBC power supply module 510 is consistent, which can improve the consistency of its output voltage.

[0201] In some embodiments, see Fig.12As shown, the vehicle integrated domain controller architecture also includes a sampling module 520, which is used to perform voltage sampling on the sampling nodes of the low-voltage battery 300, the battery management module 100, the low-voltage power distribution module 200 and the thermal management module 900 and generate electrical parameter sampling signals. The controller 120 is connected to the sampling module 520, and the controller 120 is also used to control the working state of the low-voltage battery 300 according to the electrical parameter sampling signals.

[0202] In this embodiment, by setting multiple sampling nodes in the battery management module 100, the low-voltage power distribution module 200 and the thermal management module 900, and sampling the voltages of the multiple sampling nodes to obtain electrical parameter sampling signals, the controller 120 determines whether the voltage of the sampling node corresponding to the electrical parameter sampling signal meets the working conditions of the current working state according to the received electrical parameter sampling signal, so that the controller 120 controls the working state of the battery management module 100, so that the battery management module 100 can adjust the parameters of the low-voltage battery 300 according to the electrical parameters of the sampling nodes in real time, thereby reducing the safety hazards caused by line faults. For example, when the voltage of the input node of the low-voltage power distribution module 200 is undervoltage, the output voltage or output current of the low-voltage battery 300 is increased by the battery management module 100, so as to achieve the purpose of increasing the output power of the low-voltage battery 300 according to the power demand of the load end.

[0203] In some embodiments, the sampling module 520 is used to sample current at the sampling nodes of the low-voltage power distribution module 200 and the thermal management module 900 and generate electrical parameter sampling signals; the controller 120 is also used to control the working state of the battery management module 100 according to the electrical parameter sampling signals.

[0204] In this embodiment, by setting multiple sampling nodes in the battery management module 100, the low-voltage power distribution module 200 and the thermal management module 900, and sampling the currents of the multiple sampling nodes to obtain electrical parameter sampling signals, the controller 120 determines whether the current of the sampling node corresponding to the electrical parameter sampling signal meets the working conditions of the current working state according to the received electrical parameter sampling signal, thereby controlling the working state of the battery management module 100, so that the battery management module 100 can adjust the working state of the low-voltage battery 300 according to the electrical parameters of the low-voltage battery 300, the low-voltage power distribution module 200 and the thermal management module 900 in real time, and reduce the safety hazards caused by line faults. For example, when the current of the input node of the battery management module 100 is too high, the charging current of the battery management module 100 to the low-voltage battery 300 can be reduced by controlling the working state of the battery management module 100, thereby reducing the risk of safety hazards of the battery caused by excessive charging current.

[0205] In some embodiments, the low-voltage power distribution module 200 and the battery management module 100 are integrated on the same first circuit board 123. The low-voltage power distribution module 200 and the battery management module 100 are connected. Only the common node of the low-voltage power distribution module 200 and the battery management module 100 needs to be sampled to sample their output current, which can save at least one current sampling chip, thereby achieving the purpose of saving the cost of the control system.

[0206] In some embodiments, the sampling module 520 is used to perform current sampling and voltage sampling on the sampling nodes of the low-voltage battery 300, the battery management module 100, the low-voltage power distribution module 200 and the thermal management module 900 and generate electrical parameter sampling signals. The controller 120 is also used to control the working state of the low-voltage power distribution module 200 according to the electrical parameter sampling signals.

[0207] In this embodiment, by setting multiple sampling nodes in the battery management module 100, the low-voltage power distribution module 200 and the thermal management module 900, and sampling the voltage or current of the multiple sampling nodes to obtain an electrical parameter sampling signal, the controller 120 determines whether the voltage or current of the sampling node corresponding to the electrical parameter sampling signal meets the working conditions of the current working state based on the received electrical parameter sampling signal, thereby controlling the working state of the low-voltage power distribution module 200, so that the low-voltage power distribution module 200 can adjust the working state in real time according to the electrical parameters of the battery management module 100, the low-voltage power distribution module 200 and the thermal management module 900, thereby reducing safety hazards caused by line failures or failures of the low-voltage battery 300.

[0208] For example, when the voltage of the output node of the low-voltage power distribution module 200 is undervoltage, or the output node of the low-voltage power distribution module 200 is overloaded, the low-voltage battery 300 and the low-voltage power input terminal 400 can be connected at the same time by controlling the working state of the low-voltage power distribution module 200, thereby increasing the input power of the low-voltage power distribution module 200, achieving the purpose of adjusting the input power according to the load demand power of the output end, and reducing the risk of safety hazards caused by output end overload.

[0209] In some embodiments, the sampling module 520 can also sample the temperatures of multiple sampling nodes set in the low-voltage battery 300, the low-voltage power distribution module 200, the battery management module 100 and the thermal management module 900 to obtain corresponding temperature sampling signals. The controller 120 determines whether the temperature of the sampling node corresponding to the temperature sampling signal meets the working conditions of the current working state based on the received temperature sampling signal, thereby controlling the working state of the low-voltage power distribution module 200, the battery management module 100 and the thermal management module 900, so that the low-voltage power distribution module 200, the battery management module 100 and the thermal management module 900 can adjust their working states in real time according to the temperatures of their sampling nodes, thereby reducing the problem of safety hazards to the vehicle caused by the temperature of the vehicle temperature sampling node exceeding the threshold temperature range.

[0210] In some embodiments, the controller 120 includes at least two cores. After the low-voltage power distribution module 200, the battery management module 100 and the thermal management module 900 reuse the same controller 120, the data collected by the sampling module 520 can be directly output to the controller 120 and processed uniformly by the controller 120. There is no need for the upper-level processor to send messages through the CAN bus, and there is no need to be affected by the outside world, thereby reducing the problem of information loss caused by message failure.

[0211] In some embodiments, when the low-voltage load access terminal 210 is connected to multiple power loads, the controller 120 controls the multiple low-voltage load access terminals 210 of the low-voltage power distribution module 200 to be powered on in a time-sharing manner.

[0212] In this embodiment, multiple low-voltage load access terminals 210 of the low-voltage power distribution module 200 can be respectively connected to multiple power loads. When multiple power loads are connected, the controller 120 controls the multiple low-voltage load access terminals 210 to power on in time, thereby meeting the power requirements of multiple low-voltage loads without increasing or significantly increasing the output current of the low-voltage power distribution module 200, thereby avoiding the problem of multiple low-voltage load access terminals 210 being powered on at the same time, resulting in excessive output current and causing safety hazards.

[0213] In some embodiments, see Fig.13 As shown, the vehicle integrated domain controller architecture also includes an AFE module 530 , which is connected to the low-voltage battery 300 and the controller 120 , respectively. The AFE module 530 is used to collect information from the low-voltage battery 300 and to exchange information with the controller 120 .

[0214] In this embodiment, the AFE module 530 is connected to the low-voltage battery 300 and the controller 120 at the same time, and the AFE module 530 can collect information from the low-voltage battery 300 and exchange information with the controller 120.

[0215] In some embodiments, the controller 120 is connected to the AFE module 530 via a non-multiplexed synchronous serial communication interface.

[0216] In this embodiment, the controller 120 is connected to the AFE module 530 through a non-multiplexed synchronous serial communication interface, and high-speed full-duplex communication can be established between the controller 120 and the AFE module 530. The data pin of the controller 120 performs a set type of data transmission. For example, each communication module corresponds to an interactive function module and may not be affected by other pins or modules.

[0217] In some embodiments, the output voltage range of the low voltage battery 300 is 12V-72V.

[0218] In some embodiments, the low voltage battery 300 includes a 12 volt lithium ion battery or a sodium ion battery, or other rechargeable battery.
