Therefore, they should not be construed as limitations on the embodiments of this application.

[0057] In related technologies, low-voltage power distribution systems employ discrete low-voltage lithium-ion battery technology, while simultaneously integrating a separate thermal management system on other circuit boards. These two independently configured products not only suffer from large size and inability to integrate control, but also require numerous redundant components, increasing system costs. For example, in current vehicle power supply systems, area controllers are typically used to control various functional modules within the vehicle. Therefore, each functional module requires an independent controller to process data and control the devices within that module. Similarly, each functional module also requires an independent SBC module to power the controller, and an independent AFE module to establish communication between the control module and the host computer. This control architecture not only requires extensive wiring harnesses but also suffers from large size and inconvenient maintenance.

[0058] To address the aforementioned technical problems, this application provides a vehicle-integrated direct-drive thermal management controller architecture. This architecture includes a low-voltage battery 300, a battery management module 100, and a thermal management module 900. The low-voltage battery 300 is connected to the battery management module 100, which manages the charging and discharging of the low-voltage battery 300. The thermal management module 900 manages the operation of the thermal management load by configuring a load access terminal 210 on the battery management module 100 for connecting the thermal management load. The thermal management module 900 can control the operating state of the thermal management load. The battery management module 100 and the thermal management module 900 share the same controller 120, which integrates the functions of managing the low-voltage battery 300 and the thermal management load.

[0059] In this embodiment, the thermal management load can be used to control the temperature of various nodes in the vehicle. For example, the thermal management load includes an air conditioning water pump and a motor water pump. The air conditioning water pump is used to regulate the temperature of the vehicle's air conditioning system, and the motor water pump is used to regulate the temperature of the vehicle's motor. The battery management module 100 and the thermal management module 900 share the same controller 120, that is, the battery management module 100 and the thermal management module 900 include the same controller 120. The battery management module 100 manages the charging and discharging of the low-voltage battery 300. For example, the battery management module 100 configures the output power of the low-voltage battery 300 according to the power requirements of the output terminal of the battery management module 100, and can also charge the low-voltage battery 300 when an external power source is connected. The thermal management module 900 manages the thermal management load. By integrating the functions of managing the low-voltage battery 300 and the thermal management load into the controller 120, it creatively integrates the control modules of the battery management scheme and the thermal management scheme into the same controller 120. It integrates the reusable parts of the battery management scheme and the thermal management scheme, simplifies the control circuit, and has the characteristics of low cost and simple architecture.

[0060] In some specific application embodiments, in the vehicle low-voltage power distribution system, the controller 120 and a portion of power devices form a battery management module 100. In the vehicle thermal management system, the controller 120 and its external thermal management drive unit form a thermal management module 900. In this embodiment, by integrating the vehicle low-voltage power distribution system and the vehicle thermal management system, the same controller 120 is used to control and manage both systems. By integrating the functions of managing the low-voltage battery 300 and the thermal management load, as well as the function of power distribution control for the low-voltage load, the communication harnesses between the independent low-voltage power distribution system and the independent thermal management system are reduced. Furthermore, there is no need to set up a separate controller and related SBC power supply chips, saving the number of chips used and reducing the probability of power supply and communication harness failures in the vehicle low-voltage power distribution system.

[0061] In this embodiment, the controller 120 integrates the function of managing the low-voltage battery 300 and the thermal management load. After the vehicle is started, the controller 120 can manage the energy output of the vehicle's low-voltage power distribution system based on the vehicle's thermal management feedback information, and can also manage the working status of the thermal management load based on the energy output of the vehicle's low-voltage power distribution system. This allows the vehicle's low-voltage power distribution system and the vehicle's thermal management system to adapt to each other based on the current vehicle condition, thereby improving the energy utilization efficiency and power supply stability of the vehicle's low-voltage power distribution system.

[0062] In some specific application embodiments, the controller 120 and a portion of power devices form a battery management module 100, and the controller 120 and the thermal management drive unit form a thermal management module 900. Without the need for a bulky fuse box, the battery management module 100, the thermal management module 900, and the low-voltage battery 300 can be further integrated into the low-voltage battery assembly. This not only reduces the size 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, reducing the probability of power and communication wiring harness failures in the vehicle's low-voltage power distribution system and thermal management system.

[0063] In some embodiments, the battery management module 100 may be configured with multiple load access terminals 210. The multiple load access terminals 210 can be used not only to connect thermal management loads, but also to connect other low-voltage loads (such as sensors or other low-current electrical loads), and the output power of the load access terminals 210 can be controlled by the battery management module 100.

[0064] In some embodiments, the thermal management module 900 may be powered by a low-voltage battery 300 or an externally connected low-voltage power supply.

[0065] In this embodiment, the vehicle integrated direct-drive thermal management controller architecture may further include a low-voltage power input terminal. The low-voltage power input terminal can be connected to a low-voltage power supply obtained by conversion from the power battery. The thermal management module 900 may be powered by the low-voltage battery 300 or the low-voltage power supply. For example, the DC power output from the low-voltage battery 300 or the low-voltage power supply may be output to the load access terminal 210 and output to the thermal management load via the load access terminal 210.

[0066] In some embodiments, see Figure 3 As shown, the battery management module 100 includes a first switch module 101, which is used to manage the charging and discharging process of the low-voltage battery 300 under the control of the controller 120.

[0067] In this embodiment, the first switch module 101 is controlled by the controller 120. The controller 120 controls the switching state of the first switch module 101 to perform the charging and discharging operation of the low-voltage battery 300. This allows the low-voltage power distribution module 200 to reuse the first switch module 101 as its power distribution management unit. There is no need to set up a power distribution management device in the low-voltage power distribution module 200. In addition, the wiring harness between the low-voltage power distribution module 200 and the battery management module 100 is reduced, which reduces the safety hazards caused by short circuits in the wiring harnesses between different circuit boards.

[0068] In some specific application embodiments, the first switch module 101 and the controller 120 form a battery management module 100. The low-voltage battery 300 is connected to the low-voltage power distribution module 200 via the first switch module 101. Connecting the low-voltage battery 300 and the low-voltage power distribution module 200 via the first switch module 101 not only allows the low-voltage power distribution module 200 to reuse the first switch module 101 to regulate and manage the current input to the low-voltage power distribution module 200, but also provides short-circuit protection for the low-voltage battery 300, reducing safety hazards caused by the failure of the low-voltage battery 300.

[0069] In some embodiments, the low-voltage battery 300 is electrically connected to the low-voltage power distribution module 200 via the first switch module 101.

[0070] In this embodiment, the first switch module 101 is connected between the low-voltage battery 300 and the low-voltage power distribution module 200. The low-voltage battery 300 is electrically connected to the low-voltage power distribution module 200 via the first switch module 101. The first switch module 101 is controlled by the controller 120, which 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, reducing the wiring harness between the low-voltage power distribution module 200 and the battery management module 100, and reducing the safety hazards caused by short circuits in the wiring harnesses between different circuit boards.

[0071] In some embodiments, the controller 120 is also connected to a thermal management load, and the controller 120 is used to send thermal management control signals to the thermal management load to manage the thermal management load.

[0072] In this embodiment, the controller 120 can be directly connected to the thermal management load and send thermal management control signals to the thermal management load. The thermal management load can adjust its own state according to the received thermal management control signals, so as to achieve the purpose of thermal management of the vehicle under the condition of sharing the same controller with the battery management module 100.

[0073] In some embodiments, the thermal management module 900 includes a plurality of thermal management drive units, which are used to manage the thermal management load according to the thermal management control commands sent by the controller 120.

[0074] In this embodiment, the load access terminal 210 connects 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 command sent by the controller. The thermal management load does not need to be connected to a separate power supply or a separate control line, thereby realizing direct driving of the thermal management load, simplifying the wiring layout of the thermal management load and reducing the thermal management load path.

[0075] In one embodiment, the thermal management module 900 further 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 120.

[0076] In this embodiment, the thermal management power distribution unit 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 connected to the load access terminal 210. 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. The thermal management load does not need to be connected to a separate power supply or a separate control line, thereby realizing direct driving of the thermal management load, simplifying the line layout of the thermal management load, and reducing the thermal management load path.

[0077] In some embodiments, the thermal management module 900 further 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.

[0078] In this embodiment, the thermal management power 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 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.

[0079] In some embodiments, the thermal management power distribution unit may include multiple power devices, which together form a switching circuit for outputting low-voltage DC power from the low-voltage battery 300 to multiple thermal management drive units, and is controlled by the controller 120 to manage the power supply status of each thermal management drive unit.

[0080] In some embodiments, the thermal management module 900 further includes a plurality of sensor units, which are used to sample the sampling nodes in the thermal management load to obtain thermal management sampling signals and send them to the controller 120. The controller 120 is also used to adjust the state of the thermal management drive unit according to the thermal management sampling signals.

[0081] In this embodiment, the thermal management load is sampled by the sensor unit to obtain the working status of the thermal management load. The controller determines whether the thermal management load is malfunctioning based on the sampled thermal management signal and adjusts the state of the thermal management drive unit in real time to reduce the probability of safety hazards in the vehicle.

[0082] In some embodiments, the thermal management drive unit includes 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 shut-off valve control unit, a stepper motor control unit, and a blower control unit.

[0083] Specifically, the motor-driven water pump control unit is controlled by the controller 120, and is used to control and drive the motor-driven water pump; the battery-driven water pump control unit is controlled by the controller 120, and is used to control and drive the battery-driven water pump; the air conditioning water pump control unit is controlled by the controller 120, and is used to control and drive the air conditioning water pump; the fan control unit is controlled by the controller 120, and is used to control and drive the electric fan; the water valve control unit is controlled by the controller 120, and is used to control and drive the water valve; the air intake grille control unit is controlled by the controller 120, and is used to control and drive the active air intake grille; the expansion valve control unit is controlled by the controller 120, and is used to control and drive the expansion valve; the shut-off valve control unit is controlled by the controller 120, and is used to control and drive the shut-off valve; the stepper motor control unit is controlled by the controller 120, and is used to control and drive the single and double polar stepper motor dampers; the blower control unit is controlled by the controller 120, and is used to control and drive the blower.

[0084] In some embodiments, the motor water pump control unit, battery water pump control unit, air conditioning water pump control unit, fan control unit, water valve control unit, air intake grille control unit, expansion valve control unit, shut-off valve control unit, stepper motor control unit, and blower control unit can be switching devices, or they can be full-bridge drive circuits or half-bridge drive circuits.

[0085] The full-bridge drive circuit, also known as the H-bridge drive circuit, has four switching arms. The switching arms can be MOSFETs or transistors. The four switching arms are controlled by the controller 120. The controller 120 provides corresponding drive control signals to control the switching state of the four switching 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.

[0086] In the field of power electronics, a full-bridge drive circuit controls the switching of four transistors (such as MOSFETs and bipolar transistors) to force the motor to change its frequency and direction. Its control signal can be PWM modulated to achieve different speeds and directions of the motor. A half-bridge drive controls the speed and direction of the motor by controlling the switching of two transistors; this control signal can also be PWM modulated. Half-bridge drives are suitable for driving low-power motors, such as electric fans.

[0087] Half-bridge gate drivers are widely used in various AC drives, DC-DC converters and other power control applications. Both full-bridge and half-bridge drivers are circuits used to control motors or other loads. They use MOSFETs as switches to control the current of thermally managed loads.

[0088] In some embodiments, the thermal management load includes at least one of a motor water pump, a battery water pump, an air conditioning water pump, an electric fan, a water valve, an active air intake grille, an expansion valve, a shut-off valve, a single or double polarity stepper motor damper, and a blower.

[0089] In some embodiments, see Figure 2 As shown, the vehicle integrated direct-drive thermal management controller architecture also includes a sampling module 520, which is used to sample the voltage of the sampling nodes of the battery management module 100 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.

[0090] In this embodiment, by setting multiple sampling nodes in the battery management module 100 and the thermal management module 900, and sampling the voltage of multiple sampling nodes to obtain corresponding electrical parameter sampling signals, the status monitoring of the low-voltage battery 300 and the thermal management load is realized. The controller 120 determines whether the voltage of the sampling node corresponding to the received electrical parameter sampling signal meets the working conditions of the current working state based on the received electrical parameter sampling signal. Thus, the controller 120 controls the working state of the battery management module 100, enabling the battery management module 100 to adjust the parameters of the low-voltage battery 300 in real time according to the electrical parameters of the sampling nodes, reducing the safety hazards caused by the voltage in the line exceeding the safety threshold. For example, when the voltage of the input node of the battery management module 100 is undervoltage, the battery management module 100 increases the output voltage or output current of the low-voltage battery 300 to increase the output power of the low-voltage battery 300 according to the power demand of the load.

[0091] In some embodiments, the sampling module 520 is used to sample the current of the sampling nodes of the battery management module 100 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.

[0092] In this embodiment, multiple sampling nodes are set in the battery management module 100 and the thermal management module 900, and the current of the multiple sampling nodes is sampled to obtain electrical parameter sampling signals. The controller 120 determines whether the current of the sampling node corresponding to the received electrical parameter sampling signal meets the working conditions of the current working state, thereby controlling the working state of the battery management module 100. This allows the battery management module 100 to adjust the working state of the low-voltage battery 300 in real time according to the electrical parameters of the low-voltage battery 300 and the thermal management module 900, reducing 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 caused by excessive charging current.

[0093] 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, 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.

[0094] In this embodiment, multiple sampling nodes are set in the low-voltage battery 300, battery management module 100, and thermal management module 900, and sampling signals are obtained by sampling the voltage or current of the multiple sampling nodes. The controller 120 determines whether the voltage or current of the sampling node corresponding to the received sampling signal meets the working conditions of the current working state, thereby controlling the working state of the battery management module 100. This allows the battery management module 100 to adjust its working state in real time according to the electrical parameters of the low-voltage battery 300, battery management module 100, and thermal management module 900, reducing safety hazards caused by line faults or low-voltage battery 300 failures.

[0095] For example, when the output node of the battery management module 100 is undervoltage or overloaded, by controlling the working state of the battery management module 100, both the low-voltage battery 300 and the low-voltage power input terminal 400 can be connected simultaneously, thereby increasing the input power of the battery management module 100. This achieves the purpose of adjusting the input power according to the load demand of the output terminal, reducing the risk of safety hazards caused by overload at the output terminal.

[0096] In some embodiments, the controller 120 is also used to control the operating state of the thermal management module 900 based on the electrical parameter sampling signal.

[0097] In this embodiment, multiple sampling nodes are set in the low-voltage battery 300, battery management module 100, and thermal management module 900, and sampling signals are obtained by sampling the voltage or current of the multiple sampling nodes. The controller 120 determines whether the voltage or current of the sampling node corresponding to the received sampling signal meets the working conditions of the current working state, thereby controlling the working state of the thermal management drive unit. This allows the thermal management drive unit to adjust its working state in real time according to the sampling signal, control the working state of the thermal management load, and reduce the safety hazards caused by thermal management load overload.

[0098] In some embodiments, the sampling module 520 is further configured to perform temperature sampling on the sampling nodes of the low-voltage battery 300 and the thermal management load to obtain a temperature sampling signal; the controller 120 is further configured to control the operating state of the low-voltage battery 300 according to the temperature sampling signal.

[0099] In this embodiment, the controller 120 determines whether the temperature of the sampling node corresponding to the received 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 battery management module 100 and the thermal management module 900. This allows the battery management module 100 and the thermal management module 900 to adjust their working state in real time according to the temperature of their sampling nodes, reducing safety hazards caused by excessively high temperatures inside the vehicle.

[0100] In some embodiments, see Figure 3 As shown, the vehicle integrated direct-drive thermal management controller architecture in this embodiment also includes a low-voltage power input terminal 400, which is electrically connected to the battery management module 100. The low-voltage power input terminal 400 can be used to connect to the low-voltage power obtained by the power battery. The battery management module 100 can control the charging of the low-voltage battery according to the input low-voltage power, and can also perform power distribution on the input low-voltage power and output it to the load access terminal 210.

[0101] In this embodiment, the low-voltage power input terminal 400 is used to connect to the low-voltage power supply obtained by voltage conversion from the power battery. The battery management module 100 distributes the low-voltage power supply to the load access terminal 210. For example, in the case of multiple load access terminals 210, the power is distributed according to the power requirements of the load connected to each load access terminal 210, or the power is distributed according to the working state of the connected load, so as to realize the dynamic adjustment of the output power of the low-voltage power supply and achieve the purpose of protecting the battery and the load.

[0102] In some embodiments, see Figure 4As shown, the vehicle integrated direct-drive thermal management controller architecture includes a circuit board 125, a battery management module 100 and a thermal management module 900 integrated on the circuit board 125, and a controller 120 also integrated on the circuit board 125.

[0103] In this embodiment, the battery management module 100 and the thermal management module 900 share the same controller 120. The controller 120 and the thermal drive device form the thermal management module 900, while the controller 120 and other drive devices form the battery management module 100. The controller 120 is soldered onto the circuit board 125 and connected to the thermal drive device and other drive devices via traces on the circuit board. The controller 120 sends thermal drive control signals to the thermal drive device to perform the function of thermal management load management, which can reduce packet loss caused by data communication between circuit boards. The battery management module 100, composed of the controller 120 and some of its peripheral drive devices, manages the state of the low-voltage battery 300 and realizes the charging and discharging management of the low-voltage battery 300. This avoids the problem of needing a large number of wiring harnesses between circuit boards due to the original independent setting of the battery management module 100 and the thermal management module 900, and reduces the probability of wiring harness failure by simplifying the wiring.

[0104] In some embodiments, the external pins of the controller 120 can not only form a battery management module 100 with the driving devices on the circuit board 125 and a thermal management module 900 with the thermal driving devices on the circuit board 125, but also form a low-voltage power distribution module with related peripheral devices, thereby achieving the effect of expanding the driving scheme.

[0105] In some embodiments, the controller 120 may also extend its external pins. For example, by soldering its external extension pins to the extension lines on the circuit board 125 and connecting the extension lines on the circuit board 125 through multiple pads, the external extension pins of the controller 120 can be functionally customized and reused to achieve the purpose of customizing vehicle functions.

[0106] In some embodiments, see Figure 5 As shown, the vehicle integrated direct-drive thermal management controller architecture also includes a vehicle heat sink 310, a low-voltage battery 300 disposed on the first side of the vehicle heat sink 310, and a circuit board 125 disposed 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. The vehicle heat sink 310 is used to dissipate heat from the circuit board 125 and the low-voltage battery 300.

[0107] In this embodiment, the circuit board 125 and the low-voltage battery 300 are respectively disposed on both sides of the same vehicle heat sink 310. By sharing the same vehicle heat sink 310 with the circuit board 125 and the low-voltage battery 300, the heat dissipation efficiency inside the vehicle can be improved and the size of the vehicle can be reduced.

[0108] In this embodiment, the thermal drive device on the circuit board 125 is connected to the thermal management load, which is located in multiple positions throughout the vehicle. By integrating the battery management module 100 and the thermal management module 900 onto the circuit board 125, not only can the wiring harness length between the thermal drive device and the controller 120 be reduced, but the temperature of the low-voltage battery 300 can also be managed by integrating the relevant thermal drive device on the circuit board 125, thereby reducing the signal transmission distance and the size of the vehicle.

[0109] In some embodiments, see Figure 6 As shown, the low-voltage battery 300 is located inside the lower cover 127 of the product. The lower cover 127 has a concave structure and is detachably connected to the upper cover 126 of the product. After the lower cover 127 and the upper cover 126 are assembled, they form a storage cavity. The circuit board 125, the vehicle heat sink 310, and the low-voltage battery 300 are stacked. The circuit board 125 and the vehicle heat sink 310 are fixed by a mounting structure. The distance between the circuit board 125, the vehicle heat sink 310, and the low-voltage battery 300 can be set according to the heat dissipation requirements and wiring harness requirements.

[0110] In some embodiments, the vehicle heat sink 310 can be a water-cooled plate disposed between the circuit boards 125. After the vehicle is started, the water-cooled plate absorbs the heat emitted by the circuit boards 125, thereby improving the space utilization efficiency inside the vehicle and reducing the size and volume of the vehicle's power distribution system.

[0111] In some embodiments, the sampling module 520 can also sample the temperature of multiple sampling nodes set in the low-voltage battery 300, battery management module 100, and thermal management module 900 to obtain corresponding sampling signals. The controller 120 determines whether the temperature of the sampling node corresponding to the received sampling signal meets the working conditions of the current working state based on the received sampling signal, thereby controlling the working state of the battery management module 100 and thermal management module 900. This allows the battery management module 100 and thermal management module 900 to adjust their working state in real time according to the temperature of their sampling nodes, reducing safety hazards caused by line faults.

[0112] In some embodiments, the controller 120 includes at least two cores, and multiple functions of the controller 120 can be distributed to multiple cores to improve the processing efficiency of the controller 120.

[0113] In this embodiment, after 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 it is not affected by external factors, which reduces the problem of information loss caused by message failure.

[0114] 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 corresponding control signals based on the control data to control the working state of the low-voltage battery 300.

[0115] In this embodiment, the controller 120 includes at least two cores. One or some of the cores can be used to process the sampling signal to obtain the corresponding sampling data, and the other core or some of the cores can be used to process the sampling data to obtain control data according to a preset calculation. Based on the control data, a control signal is generated and output to the peripheral driving device. The working state of the low-voltage battery 300 is controlled by controlling the working state of the driving device.

[0116] In some embodiments, at least one core of the controller 120 is used to process the sampling signal of the thermal management load to obtain sampling data. At least one core of the controller 120 is used to generate control data based on the sampling data and output corresponding control signals based on the control data to control the thermal drive devices and drive devices around the controller 120, thereby realizing the management of the low-voltage battery 300 and the low-voltage drive load.

[0117] In this embodiment, the controller 120 includes at least two cores. One or some of the cores can be used to process the sampling signal to obtain the corresponding sampling data, and the other core or some of the cores can be used to process the sampling data to obtain control data according to a preset calculation. Based on the control data, a control signal is generated and output to the peripheral driving device. The working state of the low-voltage battery 300 and the low-voltage driving load is controlled by controlling the working state of the thermal driving device and the driving device.

[0118] 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 corresponding control signals based on the control data to control the power distribution of the thermal management load.

[0119] In this embodiment, the controller 120 includes at least two cores. One or more of the cores can be used to process the sampling signal to obtain the corresponding sampling data, and the other core or a portion of the cores can be used to process the sampling data to obtain control data according to a preset calculation. Based on the control data, a control signal is generated and output to the peripheral thermal drive device. The working state of the thermal management load is controlled by controlling the working state of the thermal drive device.

[0120] In some embodiments, the battery management module 100 manages the charging and discharging process of the low-voltage battery 300, and the thermal management module 900 controls the operating state of the thermal management load. The battery management module 100 and the thermal management module 900 reuse the same controller 120, which integrates the power supply module of the battery management system and the power supply module of the thermal management system into one, and integrates the communication module of the battery management system and the communication module of the thermal management system into one. Under the simultaneous management and control of the thermal management load and the low-voltage battery 300 by the controller 120, the functions of the whole vehicle are highly centralized and some functional modules are reused, which greatly reduces the cost of the whole vehicle.

[0121] In some embodiments, see Figure 7 As shown, the vehicle integrated direct-drive thermal management 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.

[0122] In this embodiment, the SBC power supply module 510 in the vehicle integrated direct drive thermal management controller architecture can be integrated into the battery management module 100 or into the thermal management module 900. The power source of the SBC power supply module 510 can be the low-voltage battery 300.

[0123] 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.

[0124] 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 needing additional wiring harnesses to draw power from an external power source.

[0125] In some embodiments, the power input terminal of the SBC power supply module 510 can be simultaneously connected to the low-voltage battery 300 and the low-voltage power input terminal 400. An anti-reverse current circuit is provided between the power input terminal of the SBC power supply module 510 and the low-voltage battery 300, and an anti-reverse current circuit is provided between the power input terminal of the SBC power supply module 510 and the low-voltage power input terminal 400. This can prevent current backflow generated when the low-voltage battery 300 and the low-voltage power input terminal 400 output current, thereby improving the safety of the power supply circuit.

[0126] The System Base Chip (SBC) provides the operating voltage for the controller 120 and its peripheral devices. Without SBC power, the peripheral devices of the controller cannot function. In this embodiment, the controller 120 and some power devices form a battery management module 100, and the controller 120 and some thermal management drive units form a thermal management module 900. The controller 120 integrates functions for managing the low-voltage battery 300 and for power distribution control of the low-voltage load. Therefore, by outputting multiple voltages from the input power supply through the SBC power supply module 510, power can be supplied to the controller 120 and its peripheral power devices. Only one SBC chip is needed to power the components of the vehicle's low-voltage power distribution system and thermal management system, saving on the need for an SBC chip and also... The power management scheme of the low-voltage power distribution system is optimized, which reduces the performance instability caused by inconsistent power supply voltage in the independent SBC scheme 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 one independent 3.3V power supply to power the controller 120. In addition, it can also output one independent 3.3V power supply to power the analog chip on the circuit board 125 and one independent 5V power supply to power the communication chip on the circuit board 125. The input power supply of the SBC power supply module 510 is consistent, which can improve the consistency of its output voltage.

[0127] In some embodiments, when multiple electrical loads are connected to the load access terminal 210, the controller 120 controls the multiple load access terminals 210 of the battery management module 100 to be powered on in a time-sharing manner.

[0128] In this embodiment, the multiple load access terminals 210 of the battery management module 100 can be connected to multiple electrical loads respectively. When multiple electrical loads are connected, the controller 120 can increase the output current of the battery management module 100 by controlling the multiple load access terminals 210 to power on in a time-sharing manner, thereby avoiding the problem of excessive output current caused by multiple load access terminals 210 being powered on at the same time, which could lead to safety hazards.

[0129] In some embodiments, see Figure 8As shown, the vehicle integrated direct-drive thermal management 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 interact with the controller 120.

[0130] In this embodiment, the AFE module 530 is connected to both the low-voltage battery 300 and the controller 120. The AFE module 530 can collect information from the low-voltage battery 300 and interact with the controller 120. In some embodiments, the controller 120 is connected to the AFE module 530 via a non-multiplexed synchronous serial communication interface.

[0131] In this embodiment, the controller 120 is connected to the AFE module 530 through a non-multiplexed synchronous serial communication interface, which can establish high-speed full-duplex communication between the controller 120 and the AFE module 530. The data pins of the controller 120 perform data transmission of a set type. For example, each communication module corresponds to an interactive function module and can be unaffected by other pins or modules.

[0132] In some embodiments, see Figure 9 As shown, the battery management module 100 includes a first switch module 101, which is controlled by the controller 120. The low-voltage battery 300 is electrically connected to the battery management module 100 via the first switch module 101.

[0133] In this embodiment, the first switch module 101 is connected between the low-voltage battery 300 and the battery management module 100. The first switch module 101 is controlled by the controller 120, which controls the switching state of the first switch module 101 to perform the charging and discharging operation of the low-voltage battery 300. This allows the battery management module 100 to reuse the first switch module 101, reducing the wiring harness between the battery management modules 100 and reducing the safety hazards caused by short circuits in the wiring harnesses between different circuit boards.

[0134] In some embodiments, the output voltage range of the low-voltage battery 300 is 12V-72V.

[0135] In some embodiments, the low-voltage battery 300 includes a 12-volt lithium-ion battery or a sodium-ion battery, or other rechargeable batteries.

[0136] In some embodiments, the low-voltage battery 300 includes a 24-volt lithium-ion battery or a sodium-ion battery, or other rechargeable batteries.

[0137] In some embodiments, the low-voltage battery 300 includes a 48-volt lithium-ion battery or a sodium-ion battery, or other rechargeable batteries.

[0138] In some embodiments, the low-voltage battery 300 includes a 72V lithium-ion battery or a sodium-ion battery, or other rechargeable batteries.
