Description

Technical Field

[0001] This application relates to the field of vehicle control technology, specifically to a vehicle energy feedback method, device, equipment, and storage medium. Background Technology

[0002] With increasing international emphasis on environmental protection, electric vehicles have ushered in a favorable development opportunity and achieved considerable success. Since the battery is a key component of electric vehicles, it is crucial for their driving range. Continuing to use the braking methods of traditional gasoline vehicles would waste a significant amount of energy, greatly hindering the improvement of the driving range of electric vehicles.

[0003] Furthermore, energy regeneration systems in electric vehicles can save 10-20% on energy consumption. These systems primarily include coasting regenerative braking and braking regenerative braking. While the design and control of electric vehicle energy regeneration systems are highly diverse, the main destination of the regenerated energy is the battery. Current research on energy regeneration focuses on selecting appropriate regenerative torque to maximize energy recovery for electric vehicles. However, the main problem with this approach is that energy regeneration cannot occur through the motor when the battery is fully charged or in low-temperature conditions that limit or eliminate charging power.

[0053] This application also provides a vehicle energy recovery device, the device comprising:

[0054] One or more processors;

[0055] A storage device for storing one or more programs that, when executed by one or more processors, cause the device to implement the vehicle energy feedback method as described above.

[0056] This application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a computer's processor, causes the computer to perform the vehicle energy feedback method as described in any of the above-described methods.

[0057] As described above, this application provides a vehicle energy recovery method, apparatus, device, and storage medium, which has the following beneficial effects:

[0058] This application first identifies vehicles that meet the energy feedback conditions as target vehicles. Then, it calculates the vehicle heater power based on the feedback power, thermal management heating power, and power battery charging power of the target vehicle. Next, it determines whether the water temperature of the thermal management system in the target vehicle exceeds a preset temperature range. If the water temperature of the thermal management system does not exceed the preset temperature range, energy feedback is performed on the target vehicle based on the vehicle heater power. If the water temperature of the thermal management system exceeds the preset temperature range, the thermal management system is cooled down. Therefore, this application can meet the maximum or relatively high power requirements of coasting feedback, ensuring that the vehicle's power battery maintains normal energy feedback capability when fully charged or with limited charging power (such as when the vehicle is cold-starting in winter). At the same time, in scenarios such as low-temperature environments where the passenger compartment needs to be heated by air conditioning and the battery needs to be heated, the battery heating time can be shortened. Furthermore, the energy from coasting or braking energy feedback can be directly transferred from the motor to the PTC (Positive-Temperature-Coefficient, automotive heater) heating management system, eliminating the need for or reducing the energy supplied by the power battery to the PTC, thereby improving the energy utilization efficiency during coasting and braking and reducing the power battery's power consumption. In addition, when the hydraulic braking system fails and the battery charging power and the power of other high-voltage components are low, it can still continuously provide a large braking force to decelerate and stop the vehicle. Simultaneously, during vehicle energy regeneration, the power battery is prioritized for charging based on its allowable charging power. When the power battery is fully charged, or its charging power is limited or unavailable for any reason, other high-voltage components besides the PTC cannot provide sufficient power consumption. In this case, the power generated by energy regeneration that the power battery cannot receive is allocated to the high-power hydrothermal PTC for consumption as heat, which heats the circulating water. The heat in the circulating water can be used by the thermal management system to heat the battery when it needs heating, or to provide heating for the passenger compartment air conditioning system in winter when the passenger compartment needs heating, or to heat other components that require heating. When there is no heating power requirement for battery heating, air conditioning heating, or other components, the heated circulating water is directly cooled by the PTC cooling system. Compared to the electro-hydraulic coupling method used for coasting regeneration, this application can reduce the smoothness problems caused by electro-hydraulic coupling and the problem of unutilized energy consumed by hydraulic braking, thereby improving the utilization rate of regenerated energy. Therefore, this application can solve the problem that energy feedback cannot be performed through the motor when the charging power is limited or lost due to the battery being fully charged or in low temperature conditions. In addition, while solving the problem, it can also shorten the battery heating time in winter and improve the heating efficiency of the air conditioner to reduce the power battery power consumption.

[0073] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application. However, it will be apparent to those skilled in the art that embodiments of the present application may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present application.

[0074] Figure 1 A schematic diagram of an exemplary system architecture that can apply the technical solutions of one or more embodiments of this application is shown. Figure 1 As shown, the system architecture 100 may include terminal device 110, network 120, and server 130. Terminal device 110 may include various electronic devices such as smartphones, tablets, laptops, and desktop computers. Server 130 may be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. Network 120 may be a communication medium of various connection types capable of providing a communication link between terminal device 110 and server 130, such as a wired communication link or a wireless communication link.

[0075] Depending on the implementation requirements, the system architecture in this application embodiment can have any number of terminal devices, networks, and servers. For example, server 130 can be a server group composed of multiple server devices. In addition, the technical solutions provided in this application embodiment can be applied to terminal device 110, or to server 130, or can be implemented jointly by terminal device 110 and server 130. This application does not impose any special limitations on this.

[0076] In one embodiment of this application, the terminal device 110 or server 130 may first identify vehicles that meet the energy feedback conditions as target vehicles, then calculate the vehicle heater power based on the feedback power, thermal management heating power, and power battery charging power of the target vehicle; then determine whether the water temperature of the thermal management system in the target vehicle exceeds a preset temperature range; if the water temperature of the thermal management system does not exceed the preset temperature range, then energy feedback is performed on the target vehicle based on the vehicle heater power; if the water temperature of the thermal management system exceeds the preset temperature range, then the thermal management system is cooled down. By using terminal device 110 or server 130 to execute the vehicle energy feedback method, the maximum power or relatively high power required for coasting feedback can be met. This ensures that the vehicle's power battery maintains normal energy feedback capability when fully charged or when charging power is limited (such as when the vehicle is cold-starting in winter). At the same time, in scenarios where the passenger compartment needs to be heated by air conditioning in low-temperature environments or when the battery needs to be heated, the battery heating time can be shortened. Furthermore, the energy from coasting or braking energy feedback can be directly transferred from the motor to the PTC heating management system, eliminating the need for or reducing the energy supplied by the power battery to the PTC, thereby improving the energy utilization efficiency during coasting and braking and reducing the power battery power consumption. In addition, when the hydraulic braking system fails and the battery charging power and the power of other high-voltage components are low, it can still continuously provide a large braking force to decelerate and stop the vehicle.

[0077] The above section introduced an exemplary system architecture that applies the technical solution of this application. Next, we will continue to introduce the vehicle energy feedback method of this application.

[0078] Figure 2 A schematic flowchart of a vehicle energy recovery method according to an embodiment of this application is shown. Specifically, in an exemplary embodiment, as follows... Figure 2 As shown, this embodiment provides a vehicle energy recovery method, which includes the following steps:

[0079] The process of acquiring a target vehicle includes vehicles that meet the energy feedback conditions. As an example, this embodiment involves: acquiring any vehicle as a vehicle to be identified; performing energy feedback condition identification on the vehicle to be identified to determine whether the vehicle meets the requirements for coasting energy feedback and / or braking energy feedback; if the vehicle meets the requirements for coasting energy feedback and / or braking energy feedback, then the vehicle to be identified is designated as the target vehicle; if the vehicle does not meet the requirements for coasting energy feedback and braking energy feedback, then the vehicle to be identified is not designated as the target vehicle.

[0080] The vehicle heater power is calculated based on the target vehicle's feedback power, thermal management heating power, and power battery charging power.

[0081] Determine whether the water temperature of the thermal management system in the target vehicle exceeds the preset temperature range;

[0082] If the water temperature of the thermal management system does not exceed the preset temperature range, energy feedback is provided to the target vehicle based on the power of the vehicle heater.

[0083] If the water temperature of the thermal management system exceeds the preset temperature range, the thermal management system will be cooled down.

[0084] According to the above description, in an exemplary embodiment, before calculating the vehicle heater power based on the target vehicle's feedback power, thermal management heating power, and power battery charging power, this embodiment further includes: calculating the target vehicle's feedback power; and, when the target vehicle's power battery needs heating, using circulating water to heat the power battery to obtain battery heating power; and, when there is an air conditioning heating request, using circulating water to heat the air conditioning heater to obtain air conditioning heating power; and, when there is a first component heating request, using circulating water to heat the first component to obtain first component heating power; wherein, the first component includes: an air conditioning compressor and a DC-DC converter; and the thermal management heating power is obtained by summing the battery heating power, the air conditioning heating power, and the first component heating power.

[0085] In an exemplary embodiment, the process of calculating the vehicle heater power based on the feedback power, thermal management heating power, and power battery charging power of the target vehicle includes: determining whether the feedback power is greater than the sum of the thermal management heating power and the power of the first component; if the feedback power is greater than the sum of the power, then subtracting the thermal management heating power and the power of the first component from the feedback power respectively, and using the difference as the power battery charging power; if the feedback power is less than or equal to the sum of the power, then setting the power battery charging power to zero; and calculating the vehicle heater power based on the feedback power, the thermal management heating power, and the power battery charging power. Furthermore, the process of calculating the vehicle heater power based on the feedback power, thermal management heating power, and power battery charging power of the target vehicle also includes: subtracting the power battery charging power, the thermal management heating power, and the heating power of the first component from the feedback power to obtain the vehicle heater dissipation power; and adding the vehicle heater dissipation power to the thermal management heating power to obtain the vehicle heater power.

[0086] In another exemplary embodiment of this application, this embodiment also provides a vehicle energy feedback method. In this embodiment, a water-thermal PTC device capable of meeting the maximum coasting feedback power or a relatively large coasting feedback power can be used, and the thermal management system is optimized to ensure that when the PTC and other high-pressure components are working, the thermal management system can guarantee sufficient cooling effect so that the operating temperature of each component is within a reasonable range. The PTC power can be selected according to vehicle requirements, but must not be lower than the maximum feedback power of standard coasting feedback. Secondly, based on the high-power PTC and optimized thermal management system, energy feedback is controlled. Under normal circumstances, the energy flow diagram of energy feedback is shown below. Figure 3 As shown, compared to the energy flow direction of traditional pure electric braking energy regeneration, the cooling fan, which undergoes a significant change, needs to undertake more work to dissipate the heat that cannot be utilized by the PTC heating. When low temperatures or limited battery charging power cause the energy regeneration power to exceed the vehicle's on-road charging power (excluding charging from external plug-in devices such as charging stations) and the power consumed by other high-voltage components, the high-power PTC described in this invention can be used for power consumption. Figure 3 In this diagram, 1 represents the wheel, 2 represents the motor, 3 represents the PTC, 4 represents the battery pack, 5 includes the air conditioning system, and 6 represents the cooling fan. Specifically, the steps combining energy feedback control with thermal management control include:

[0087] First, it is determined whether the vehicle meets the energy feedback conditions. These conditions include coasting energy feedback and braking energy feedback; meeting either one is sufficient. If the system meets the energy feedback conditions, the motor is used for energy feedback; otherwise, energy feedback control is not performed.

[0088] The second step is to calculate the regenerative power. The regenerative power is based on the traditional regenerative power, but the power limit of the PTC needs to be added, that is, regenerative power = MIN (PTC maximum power, traditional coasting regenerative or braking regenerative power).

[0089] The third step is to calculate the heating power of the thermal management system. The heating power is calculated based on whether the battery needs heating, the air conditioner needs heating, and other components need heating. That is: Thermal management heating power = Battery heating power + Air conditioner heating power + Heating power of other components.

[0090] The fourth step is to calculate the charging power of the power battery. After the feedback power meets the power requirements of other high-voltage components and the heating power of the thermal management system, it can charge the power battery. Other high-voltage components include the DC / DC converter and the air conditioning compressor. Therefore, the power battery charging power = min(maximum battery charging power, feedback power - (power of other high-voltage components + heating power of thermal management system)). If the feedback power does not meet the power requirements of other high-voltage components and the heating power of the thermal management system, the power battery will not be charged, i.e., the charging power will be 0.

[0091] The fifth step is to calculate the power dissipated by the PTC. PTC power dissipation refers to the energy dissipated into the air as heat by the PTC heating the cooling water and other media in the thermal management system, as well as the energy carried by these media and dissipated into the air as heat by the cooling fan. When the feedback power exceeds the power of other high-voltage components, the heating power of the thermal management system, and the charging power of the power battery, this power can be dissipated through the high-power PTC and the thermal management system. This portion of power is not used to perform work on the vehicle and is wasted. That is: PTC energy dissipation power = Feedback power - (Power of other high-voltage components + Heating power of thermal management + Charging power of power battery). When the feedback power does not meet the power requirements of other high-voltage components, the heating power of the thermal management system, and the charging power of the power battery, the PTC power dissipation is 0.

[0092] Step 6: Calculate the PTC power. The power of the high-power PTC includes the heating power for the thermal management system and the PTC dissipation power lost solely for the braking effect of energy feedback. This power is not present in traditional energy feedback systems and thermal management systems and is not considered in these systems. That is: PTC power = Thermal management heating power + PTC dissipation power.

[0093] The seventh step is to determine whether the cooling fan needs to be turned on to cool the thermal management system. When the heat dissipated by the high-power PTC during energy feedback causes the thermal management system temperature to become too high and exceed the reasonable range, the cooling fan needs to be turned on to cool the thermal management system. Therefore, when designing the thermal management system, it is necessary to consider optimizing the heat dissipation system to ensure that the heat dissipation capacity can meet the power dissipation requirements of the newly added high-power PTC during energy feedback.

[0094] Therefore, the biggest difference between this embodiment and the traditional method is that the PTC power is dynamically adjusted over a wide range based on the remaining power after the power consumption of other high-voltage components and battery charging. It can meet the maximum or relatively high power requirements for coasting feedback, ensuring that the vehicle's power battery maintains normal energy feedback capability when fully charged or when charging power is limited (such as during cold starts in winter). Simultaneously, in scenarios where the passenger compartment needs air conditioning heating or the battery needs heating in low-temperature environments, the battery heating time can be shortened. Furthermore, the energy from coasting or braking energy feedback can be directly transferred from the motor to the PTC heating management system, eliminating or reducing the energy supplied by the power battery to the PTC, improving energy utilization efficiency during coasting and braking, and reducing power battery power consumption. In addition, when the hydraulic braking system fails and the battery charging power and the power of other high-voltage components are low, it can still continuously provide a large braking force to decelerate and stop the vehicle. As an example, in this embodiment, the PTC heating device can also be replaced by other heating devices of the same power. Specifically, the power of a traditional PTC is generally 2-7KW. In this embodiment, the power of the water-heated PTC should be able to meet the power required for the maximum or large coasting feedback of the vehicle, such as greater than 35KW. The corresponding vehicle should have a matching air conditioning water-heated heating system and a PTC water-cooled heat dissipation system.

[0095] In another exemplary embodiment of this application, when the vehicle is undergoing energy recovery, the power battery is preferentially charged according to its allowable charging power. When the power battery is fully charged or its charging power is limited or cannot be charged for any reason, other high-voltage components (high-voltage components other than the PTC) cannot provide sufficient power consumption. In this case, the system allocates the power generated by energy recovery that the power battery cannot receive to the high-power hydrothermal PTC for consumption as heat and to heat the circulating water. The heat in the circulating water can be used by the thermal management system to heat the battery when it needs heating, or to heat the passenger compartment air conditioning system when the passenger compartment needs heating in winter, or to heat other components that need heating. When there is no heating power requirement for battery heating, air conditioning heating, or other components, the heated circulating water is directly cooled by the PTC cooling system. Compared to the electro-hydraulic coupling method used for coasting regenerative braking, such as... Figure 3 As shown, this embodiment can reduce the smoothness issues caused by electro-hydraulic coupling and the problem of unutilized energy consumed by hydraulic braking, thereby improving the utilization rate of regenerative energy. Figure 3 In the diagram, 1 represents the wheel, 2 represents the motor, 3 represents the PTC, and 4 represents the battery pack.

[0096] In summary, this application provides a vehicle energy feedback method. First, a vehicle that meets the energy feedback conditions is selected as the target vehicle. Then, the vehicle heater power is calculated based on the feedback power, thermal management heating power, and power battery charging power of the target vehicle. Next, it is determined whether the water temperature of the thermal management system in the target vehicle exceeds a preset temperature range. If the water temperature of the thermal management system does not exceed the preset temperature range, energy feedback is performed on the target vehicle based on the vehicle heater power. If the water temperature of the thermal management system exceeds the preset temperature range, the thermal management system is cooled down. Therefore, this method can meet the maximum or relatively high power requirements of coasting feedback, ensuring that the vehicle's power battery maintains normal energy feedback capability when fully charged or when charging power is limited (such as when the vehicle is cold-started in winter). At the same time, in scenarios such as low-temperature environments where the passenger compartment needs to be heated by air conditioning and the battery needs to be heated, the battery heating time can be shortened. Furthermore, the energy from coasting or braking energy feedback can be directly transferred from the motor to the PTC heating management system, eliminating the need for or reducing the energy supplied by the power battery to the PTC, thereby improving the energy utilization efficiency during coasting and braking and reducing the power battery's power consumption. In addition, when the hydraulic braking system fails and the battery charging power and the power of other high-voltage components are low, it can still continuously provide a large braking force to decelerate and stop the vehicle. Simultaneously, during vehicle energy regeneration, the system prioritizes charging the power battery based on its allowable charging power. When the power battery is fully charged, or its charging power is limited or unavailable, other high-voltage components besides the PTC cannot provide sufficient power consumption. In this case, the power generated by energy regeneration that the power battery cannot receive is allocated to the high-power hydrothermal PTC for consumption as heat, which also heats the circulating water. The heat in the circulating water can be used by the thermal management system to heat the battery when needed, or to provide heating for the passenger compartment's air conditioning system during winter, or to heat other components that require heating. When there is no heating power requirement for battery heating, air conditioning, or other components, the heated circulating water is directly cooled by the PTC cooling system. Compared to the electro-hydraulic coupling method used for coasting regeneration, this method reduces the smoothness issues caused by electro-hydraulic coupling and the problem of unutilized energy consumed by hydraulic braking, thus improving the utilization rate of regenerated energy. Therefore, this method can solve the problem of energy feedback through the motor when the charging power is limited or lost due to the battery being fully charged or in low temperature conditions. In addition to solving the problem, it can also shorten the battery heating time in winter and improve the heating efficiency of the air conditioner to reduce the power battery power consumption.

[0097] like Figure 5 As shown, this application also provides a vehicle energy recovery device, the device comprising:

[0098] Vehicle module 510 is used to acquire target vehicles, including vehicles that meet energy feedback conditions. As an example, the process of acquiring target vehicles in this embodiment includes: acquiring any vehicle as a vehicle to be identified; performing energy feedback condition identification on the vehicle to be identified to determine whether the vehicle to be identified meets the requirements of coasting energy feedback and / or braking energy feedback; if the vehicle to be identified meets the requirements of coasting energy feedback and / or braking energy feedback, then the vehicle to be identified is identified as a target vehicle; if the vehicle to be identified does not meet the requirements of coasting energy feedback and braking energy feedback, then the vehicle to be identified is not identified as a target vehicle.

[0099] Heater power module 520 is used to calculate the vehicle heater power based on the target vehicle's feedback power, thermal management heating power, and power battery charging power;

[0100] The energy feedback module 530 is used to determine whether the water temperature of the thermal management system in the target vehicle exceeds a preset temperature range; if the water temperature of the thermal management system does not exceed the preset temperature range, energy feedback is performed on the target vehicle based on the power of the vehicle heater; if the water temperature of the thermal management system exceeds the preset temperature range, the thermal management system is cooled down.

[0101] According to the above description, in an exemplary embodiment, before calculating the vehicle heater power based on the target vehicle's feedback power, thermal management heating power, and power battery charging power, the heater power module includes: calculating the target vehicle's feedback power; and, when the target vehicle's power battery needs heating, heating the power battery with circulating water to obtain battery heating power; and, when there is an air conditioning heating request, heating the air conditioning heater with circulating water to obtain air conditioning heating power; and, when there is a first component heating request, heating the first component with circulating water to obtain first component heating power; wherein, the first component includes: an air conditioning compressor and a DC-DC converter; and the thermal management heating power is obtained by summing the battery heating power, the air conditioning heating power, and the first component heating power.

[0102] In an exemplary embodiment, the process by which the heater power module calculates the vehicle heater power based on the feedback power, thermal management heating power, and power battery charging power of the target vehicle includes: determining whether the feedback power is greater than the sum of the thermal management heating power and the power of the first component; if the feedback power is greater than the sum of the power, then subtracting the thermal management heating power and the power of the first component from the feedback power respectively, and using the difference as the power battery charging power; if the feedback power is less than or equal to the sum of the power, then setting the power battery charging power to zero; and calculating the vehicle heater power based on the feedback power, the thermal management heating power, and the power battery charging power. Furthermore, the process by which the heater power module calculates the vehicle heater power based on the feedback power, thermal management heating power, and power battery charging power of the target vehicle also includes: subtracting the power battery charging power, the thermal management heating power, and the heating power of the first component from the feedback power to obtain the vehicle heater dissipation power; and adding the vehicle heater dissipation power to the thermal management heating power to obtain the vehicle heater power.

[0103] In another exemplary embodiment of this application, this embodiment also provides a vehicle energy feedback device. In this embodiment, a water-thermal PTC device capable of meeting the maximum coasting feedback power or a relatively large coasting feedback power can be used, and the thermal management system is optimized to ensure that when the PTC and other high-pressure components are working, the thermal management system can guarantee sufficient cooling effect so that the operating temperature of each component is within a reasonable range. The PTC power can be selected according to vehicle requirements, but must not be lower than the maximum feedback power of standard coasting feedback. Secondly, based on the high-power PTC and optimized thermal management system, energy feedback is controlled. Under normal circumstances, the energy flow diagram of energy feedback is shown below. Figure 3 As shown, compared to the energy flow direction of traditional pure electric braking energy regeneration, the cooling fan, which undergoes a significant change, needs to undertake more work to dissipate the heat that cannot be utilized by the PTC heating. When low temperatures or limited battery charging power cause the energy regeneration power to exceed the vehicle's on-road charging power (excluding charging from external plug-in devices such as charging stations) and the power consumed by other high-voltage components, the high-power PTC described in this invention can be used for power consumption. Figure 3 In this diagram, 1 represents the wheel, 2 represents the motor, 3 represents the PTC, 4 represents the battery pack, 5 includes the air conditioning, and 6 represents the cooling fan. Specifically, the energy feedback control device, combined with thermal management control, can perform the following steps:

[0104] First, it is determined whether the vehicle meets the energy feedback conditions. These conditions include coasting energy feedback and braking energy feedback; meeting either one is sufficient. If the system meets the energy feedback conditions, the motor is used for energy feedback; otherwise, energy feedback control is not performed.

[0105] The second step is to calculate the regenerative power. The regenerative power is based on the traditional regenerative power, but the power limit of the PTC needs to be added, that is, regenerative power = MIN (PTC maximum power, traditional coasting regenerative or braking regenerative power).

[0106] The third step is to calculate the heating power of the thermal management system. The heating power is calculated based on whether the battery needs heating, the air conditioner needs heating, and other components need heating. That is: Thermal management heating power = Battery heating power + Air conditioner heating power + Heating power of other components.

[0107] The fourth step is to calculate the charging power of the power battery. After the feedback power meets the power requirements of other high-voltage components and the heating power of the thermal management system, it can charge the power battery. Other high-voltage components include the DC / DC converter and the air conditioning compressor. Therefore, the power battery charging power = min(maximum battery charging power, feedback power - (power of other high-voltage components + heating power of thermal management system)). If the feedback power does not meet the power requirements of other high-voltage components and the heating power of the thermal management system, the power battery will not be charged, i.e., the charging power will be 0.

[0108] The fifth step is to calculate the power dissipated by the PTC. PTC power dissipation refers to the energy dissipated into the air as heat by the PTC heating the cooling water and other media in the thermal management system, as well as the energy carried by these media and dissipated into the air as heat by the cooling fan. When the feedback power exceeds the power of other high-voltage components, the heating power of the thermal management system, and the charging power of the power battery, this power can be dissipated through the high-power PTC and the thermal management system. This portion of power is not used to perform work on the vehicle and is wasted. That is: PTC energy dissipation power = Feedback power - (Power of other high-voltage components + Heating power of thermal management + Charging power of power battery). When the feedback power does not meet the power requirements of other high-voltage components, the heating power of the thermal management system, and the charging power of the power battery, the PTC power dissipation is 0.

[0109] Step 6: Calculate the PTC power. The power of the high-power PTC includes the heating power for the thermal management system and the PTC dissipation power lost solely for the braking effect of energy feedback. This power is not present in traditional energy feedback systems and thermal management systems and is not considered in these systems. That is: PTC power = Thermal management heating power + PTC dissipation power.

[0110] The seventh step is to determine whether the cooling fan needs to be turned on to cool the thermal management system. When the heat dissipated by the high-power PTC during energy feedback causes the thermal management system temperature to become too high and exceed the reasonable range, the cooling fan needs to be turned on to cool the thermal management system. Therefore, when designing the thermal management system, it is necessary to consider optimizing the heat dissipation system to ensure that the heat dissipation capacity can meet the power dissipation requirements of the newly added high-power PTC during energy feedback.

[0111] Therefore, the biggest difference between this embodiment and the traditional method is that the PTC power is dynamically adjusted over a wide range based on the remaining power after the power consumption of other high-voltage components and battery charging. It can meet the maximum or relatively high power requirements for coasting feedback, ensuring that the vehicle's power battery maintains normal energy feedback capability when fully charged or when charging power is limited (such as during cold starts in winter). Simultaneously, in scenarios where the passenger compartment needs air conditioning heating or the battery needs heating in low-temperature environments, the battery heating time can be shortened. Furthermore, the energy from coasting or braking energy feedback can be directly transferred from the motor to the PTC heating management system, eliminating or reducing the energy supplied by the power battery to the PTC, improving energy utilization efficiency during coasting and braking, and reducing power battery power consumption. In addition, when the hydraulic braking system fails and the battery charging power and the power of other high-voltage components are low, it can still continuously provide a large braking force to decelerate and stop the vehicle. As an example, in this embodiment, the PTC heating device can also be replaced by other heating devices of the same power. Specifically, the power of a traditional PTC is generally 2-7KW. In this embodiment, the power of the water-heated PTC should be able to meet the power required for the maximum or large coasting feedback of the vehicle, such as greater than 35KW. The corresponding vehicle should have a matching air conditioning water-heated heating system and a PTC water-cooled heat dissipation system.

[0112] In another exemplary embodiment of this application, when the vehicle is undergoing energy recovery, the power battery is preferentially charged according to its allowable charging power. When the power battery is fully charged or its charging power is limited or cannot be charged for any reason, other high-voltage components (high-voltage components other than the PTC) cannot provide sufficient power consumption. In this case, the system allocates the power generated by energy recovery that the power battery cannot receive to the high-power hydrothermal PTC for consumption as heat and to heat the circulating water. The heat in the circulating water can be used by the thermal management system to heat the battery when it needs heating, or to heat the passenger compartment air conditioning system when the passenger compartment needs heating in winter, or to heat other components that need heating. When there is no heating power requirement for battery heating, air conditioning heating, or other components, the heated circulating water is directly cooled by the PTC cooling system. Compared to the electro-hydraulic coupling method used for coasting regenerative braking, such as... Figure 3 As shown, this embodiment can reduce the smoothness issues caused by electro-hydraulic coupling and the problem of unutilized energy consumed by hydraulic braking, thereby improving the utilization rate of regenerative energy. Figure 3 In the diagram, 1 represents the wheel, 2 represents the motor, 3 represents the PTC, and 4 represents the battery pack.

[0113] In summary, this application provides a vehicle energy feedback device. First, a vehicle that meets the energy feedback conditions is selected as the target vehicle. Then, the vehicle heater power is calculated based on the feedback power, thermal management heating power, and power battery charging power of the target vehicle. Next, it is determined whether the water temperature of the thermal management system in the target vehicle exceeds a preset temperature range. If the water temperature of the thermal management system does not exceed the preset temperature range, energy feedback is performed on the target vehicle based on the vehicle heater power. If the water temperature of the thermal management system exceeds the preset temperature range, the thermal management system is cooled down. Therefore, this device can meet the maximum or relatively high power requirements of coasting feedback, ensuring that the vehicle's power battery maintains normal energy feedback capability when fully charged or when charging power is limited (such as when the vehicle is cold-starting in winter). At the same time, in scenarios such as low-temperature environments where the passenger compartment needs to be heated by air conditioning and the battery needs to be heated, the battery heating time can be shortened. Furthermore, the energy from coasting or braking energy feedback can be directly transferred from the motor to the PTC heating management system, eliminating the need for or reducing the energy supplied by the power battery to the PTC, thereby improving the energy utilization efficiency during coasting and braking and reducing the power battery power consumption. In addition, when the hydraulic braking system fails and the battery charging power and the power of other high-voltage components are low, it can still continuously provide a large braking force to decelerate and stop the vehicle. Simultaneously, during vehicle energy regeneration, the system prioritizes charging the power battery based on its allowable charging power. When the power battery is fully charged, or its charging power is limited or unavailable, other high-voltage components besides the PTC cannot provide sufficient power consumption. In this case, the device allocates the power generated by energy regeneration that the power battery cannot receive to the high-power hydrothermal PTC, consuming it as heat to heat the circulating water. The heat in the circulating water can be used by the thermal management system to heat the battery when needed, or to provide heating for the passenger compartment's air conditioning system during winter, or to heat other components that require heating. When there is no heating power requirement for battery heating, air conditioning, or other components, the heated circulating water is directly cooled by the PTC cooling system. Compared to the electro-hydraulic coupling method used for coasting regeneration, this device reduces the smoothness issues caused by electro-hydraulic coupling and the problem of unutilized energy consumed by hydraulic braking, thus improving the utilization rate of regenerated energy. Therefore, this device can solve the problem of energy feedback through the motor when the charging power is limited or lost due to the battery being fully charged or in low temperature conditions. In addition to solving the problem, it can also shorten the battery heating time in winter and improve the heating efficiency of the air conditioner to reduce the power consumption of the power battery.
