Description

Technical Field

[0001] The present application relates to the field of new energy vehicle technology, and more specifically, to a vehicle power supply method, device, vehicle and storage medium in the field of new energy vehicle technology. Background Art

[0002] With the increasing emphasis on environmental protection and energy sustainability, new energy technologies (such as solar energy, wind energy, etc.) have made continuous breakthroughs, promoting the innovation and upgrading of new energy vehicle power systems. New energy vehicles, especially electric vehicles, usually rely on batteries as the main energy supply and produce less tailpipe emissions, thus helping to reduce greenhouse gas emissions and improve urban air quality. However, due to the limited energy density of batteries, the energy that can be stored in batteries is relatively small within a limited volume and weight, which directly limits the endurance of new energy vehicles. For new energy vehicles that need to travel long distances or have high energy consumption requirements, limited endurance means more frequent charging needs, and in many areas, the number and distribution of charging stations are far from meeting their charging needs, resulting in users often facing charging difficulties during use, affecting the convenience of users' travel. Summary of the invention

[0003] The present application provides a vehicle power supply method, device, vehicle and storage medium. The method can flexibly select a power supply mode according to the relationship between the conversion power parameters of the electric energy output by the solar panel and the driving power parameters of the electric energy required for vehicle driving. The method can directly use the solar panel to supply power to achieve efficient energy utilization, and can also combine with the battery to supply power when solar energy is insufficient, thereby improving the flexibility of energy utilization and the endurance of the vehicle.

[0004] In a first aspect, a vehicle power supply method is provided, the method comprising: determining conversion power parameters of electric energy output by a solar panel, and determining driving power parameters of the electric energy required to drive a vehicle; when the conversion power parameters meet a first preset condition between the conversion power parameters and the driving power parameters, the vehicle is powered by the solar panel; when the conversion power parameters meet a second preset condition between the conversion power parameters and the driving power parameters, the vehicle is powered by the solar panel and a battery in the vehicle.

[0005] The beneficial effects brought about by the technical solution of the first aspect above include at least: by determining the conversion power parameters of the power output by the solar panel, the power generated by the solar panel can be obtained, and at the same time, the driving power parameters of the power required to drive the vehicle can be determined, so that the power required by the vehicle under different operating conditions can be accurately evaluated, and accurate data support can be provided for subsequent power supply decisions; when the power generated by the solar panel is sufficient to meet the needs of the vehicle, solar energy is directly used for power supply, which reduces the dependence on traditional energy and reduces the emission of greenhouse gases and the generation of other environmental pollutants; even when the power output of the solar panel is insufficient, the auxiliary power supply of the battery can be used to ensure the normal driving of the vehicle and reduce the risk of driving interruption caused by insufficient energy. In this way, through the coordinated power supply of solar panels and batteries, it is possible to directly use solar panels for power supply to achieve efficient energy utilization, and it can also be combined with battery power supply when solar energy is insufficient to improve the flexibility of energy utilization and the endurance of the vehicle.

[0006] In some possible implementations, when the conversion power parameter satisfies a first preset condition with the driving power parameter, the vehicle is powered by the solar panel, including: when the conversion power parameter is greater than or equal to the driving power parameter, determining a first conversion power in the total power output by the solar panel that is equal to the power required to drive the vehicle; converting the first conversion power into motor driving power used by a vehicle motor when driving the vehicle, and powering the vehicle with the motor driving power.

[0007] Through the technical solutions in the above possible implementation methods, when the conversion electric energy parameter of the solar panel is greater than or equal to the driving electric energy parameter required for driving the vehicle, it means that the total electric energy output by the solar panel is sufficient to supply the electric energy required for driving the vehicle. At this time, by determining the first conversion electric energy equal to the electric energy required for driving the vehicle from the total electric energy output by the solar panel, the output electric energy of the solar panel is accurately controlled according to the actual power demand of the vehicle; by converting the first conversion electric energy determined above into the motor driving electric energy used by the vehicle motor when driving the vehicle, it is ensured that the first conversion electric energy output by the solar panel can be directly and efficiently converted into electric energy that can be directly used by the driving motor, so that the vehicle can stably obtain the required electric energy and ensure the normal operation of the vehicle; in addition, because when the output electric energy of the solar panel is sufficient, the battery does not need to be discharged frequently, thereby reducing the loss and failure rate of the battery, which helps to extend the service life of the battery.

[0008] In some possible implementations, the method further includes: when the conversion power parameter is greater than the driving power parameter and the vehicle meets a preset charging condition, determining a second conversion power in the total power output by the solar panel that has not been converted into motor driving power, the preset charging condition including at least one of the vehicle battery status and light intensity; and storing the second conversion power in the battery.

[0009] Through the technical solutions in the above possible implementation methods, when the conversion electric energy parameter is greater than the driving electric energy parameter, it means that the electric energy output by the solar panel exceeds the immediate driving demand of the vehicle. At this time, if the solar panel also meets the preset charging conditions such as the vehicle battery status or light intensity, the solution can store the second conversion electric energy that is not converted into motor driving electric energy in the battery, which can not only avoid energy waste and improve the energy utilization efficiency of the entire power supply system, but also ensure sufficient battery power, provide reliable energy guarantee for the subsequent driving of the vehicle, and improve the vehicle's endurance.

[0010] In some possible implementations, when the conversion power parameter satisfies the second preset condition between the conversion power parameter and the driving power parameter, the vehicle is powered by the solar panel and the battery in the vehicle, including: when the conversion power parameter is less than the driving power parameter and the conversion power parameter is not equal to 0, the total power output by the solar panel and the power stored in the battery are converted into motor driving power used by the vehicle motor when driving the vehicle, and the vehicle is powered by the motor driving power.

[0011] Through the technical solutions in the above possible implementation methods, the dual power supply capabilities of solar panels and batteries are combined to provide stable energy support for vehicles in the case of insufficient light or limited power output of solar panels. When the converted power parameters output by the solar panel are less than the power parameters required for vehicle driving, but there is still a certain output, it is combined with the power stored in the battery and converted into motor drive power used by the vehicle motor when driving the vehicle to meet the driving needs of the vehicle. This hybrid power supply mode not only improves the comprehensive utilization efficiency of energy, but also enhances the flexibility and adaptability of the vehicle power supply system.

[0012] In some possible implementations, the method further includes: monitoring the maximum power point of the solar panel, determining circuit parameters corresponding to the maximum power point on the solar panel, the circuit parameters including at least one of a current parameter and a voltage parameter; and adjusting the circuit parameters of the solar panel based on the circuit parameters corresponding to the maximum power point.

[0013] Through the technical solutions in the above possible implementation methods, it is possible to monitor the working status of the solar panel, accurately capture the circuit parameters corresponding to its maximum power point, and dynamically adjust the circuit parameters of the solar panel based on the parameters so that it always operates near the maximum power point, thereby maximizing the capture and utilization of solar energy and improving the efficiency of power conversion.

[0014] In some possible implementations, the method further includes: monitoring the charge and discharge parameters of the battery during charging and discharging, and determining whether the charge and discharge parameters meet preset charge and discharge conditions; when the charge and discharge parameters do not meet the preset charge and discharge conditions, adjusting the circuit parameters of the battery, the circuit parameters including at least one of the current parameters and the voltage parameters.

[0015] Through the technical solutions in the above possible implementations, the charging and discharging parameters of the battery during the charging and discharging process can be monitored, and by comparing these parameters with the preset charging and discharging conditions, it can be determined whether the working state of the battery deviates from the preset safety range. When the abnormal charging and discharging state of the battery is monitored, such as overcharging or over-discharging, the circuit parameters of the battery can be dynamically adjusted to ensure that the battery is charged and discharged under appropriate conditions, preventing the battery from being damaged due to excessive charging and discharging, thereby extending the service life of the battery and reducing the maintenance cost of the user.

[0016] In some possible implementations, the method further includes: monitoring multiple power generation parameters on the solar panel, and generating power generation information corresponding to the solar panel based on each power generation parameter; triggering a device prompt message based on the power generation information, wherein the device prompt message includes at least one of a voice prompt message and a visual prompt message.

[0017] Through the technical solutions in the above possible implementation methods, multiple power generation parameters on solar panels, such as light intensity, temperature, voltage, current, etc., can be monitored in real time, which can accurately capture the working status of solar panels and generate detailed power generation information, which helps operation and maintenance personnel to understand equipment performance in a timely manner, predict potential failures, and provide data support for the realization of refined energy management. At the same time, device prompt messages triggered based on these real-time information can ensure that drivers or managers receive key information at the first time, such as sufficient power, reduced charging efficiency, or maintenance required, thereby achieving instant response and efficient processing of the power generation status of solar panels.

[0018] In a second aspect, a vehicle power supply device is provided, which includes: a parameter determination module, used to determine the conversion power parameters of the electric energy output by the solar panel, and determine the driving power parameters of the electric energy required to drive the vehicle; a first power supply module, used to power the vehicle through the solar panel when the conversion power parameter meets a first preset condition between the driving power parameter; and a second power supply module, used to power the vehicle through the solar panel and a battery in the vehicle when the conversion power parameter meets a second preset condition between the driving power parameter.

[0019] In a third aspect, a vehicle is provided, comprising a memory for storing executable program code; and a processor for calling and running the executable program code from the memory, so that the vehicle executes the method in the above-mentioned first aspect or any possible implementation of the first aspect.

[0020] In a fourth aspect, a computer program product is provided, comprising: a computer program code, which, when executed on a computer, enables the computer to execute the method in the first aspect or any possible implementation of the first aspect.

[0021] In a fifth aspect, a computer-readable storage medium is provided, which stores a computer program code. When the computer program code runs on a computer, the computer executes the method in the above-mentioned first aspect or any possible implementation manner of the first aspect.

[0027] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, such as A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" refers to two or more than two.

[0028] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. At the same time, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0029] With the increasing attention paid to environmental protection and energy sustainability around the world, new energy technologies are constantly making breakthroughs, injecting strong impetus into the innovation and upgrading of new energy vehicle power systems. As a representative of new energy vehicles, electric vehicles usually use batteries as the main energy supply, which meets the requirements of energy sustainability, helps reduce dependence on fossil fuels, and promotes the optimization of energy structure. Moreover, compared with traditional fuel vehicles, electric vehicles produce less exhaust emissions during driving, which has a significant effect on reducing greenhouse gas emissions and improving urban air quality. However, due to the limited energy density of batteries, electric vehicles can store relatively little energy under limited volume and weight, resulting in limited cruising range. For new energy vehicle users who need to travel long distances or have high energy consumption requirements, frequent charging needs and insufficient number and distribution of charging stations affect the convenience of users' travel. And compared with the convenience of refueling fuel vehicles, the charging time of electric vehicles is relatively long, which also limits the popularity and application of electric vehicles to a certain extent.

[0030] In view of the above problems existing in new energy vehicles, existing new energy vehicles have realized the effective use of solar energy by installing solar panels on the roof of the car. As a clean and renewable energy source, the application of solar energy helps to reduce dependence on traditional fossil fuels and reduce greenhouse gas emissions, thus having a positive impact on the environment. At the same time, under sufficient light conditions, solar panels can convert solar energy into electrical energy, thereby serving as an auxiliary power supply tool for batteries and providing an additional power source for vehicles, which can not only reduce the energy consumption of batteries and extend the service life of batteries, but also extend the endurance of new energy vehicles. Although existing new energy vehicles have realized their auxiliary power supply function by installing solar panels on the roof of the car, they lack real-time monitoring and management of the power generation of solar panels and the power supply needs of the vehicle itself, making it impossible for the vehicle to flexibly adjust the power source according to the current situation. This may result in the vehicle still using batteries for power supply when the solar panels generate sufficient power, thereby wasting solar energy, a renewable energy source; and when the solar panels generate insufficient power, the vehicle may not be able to switch to battery power supply in time, resulting in a decrease in endurance.

[0031] Therefore, the embodiment of the present application provides a vehicle power supply method to improve energy utilization while enhancing the vehicle's endurance, thereby injecting new vitality into the development of new energy vehicles.

[0032] See also Figure 1 , Figure 1 This is an exemplary system architecture diagram of a vehicle power supply method provided in an embodiment of the present application.

[0033] like Figure 1 As shown, the system architecture may include a vehicle 101, a network 102, and a server 103. The network 102 is used to provide a medium for a communication link between the vehicle 101 and the server 103. The network 102 may include various types of wireless communication links, such as a Bluetooth communication link, a Wireless-Fidelity (Wi-Fi) communication link, or a microwave communication link.

[0034] In an embodiment of the present application, a solar panel is integrated into the roof of the vehicle 101 or other suitable location, and when there is sufficient light, the solar panel can continuously provide additional power support for the vehicle 101. The vehicle 101 can interact with the server 103 through the network 102 to receive messages from the server 103 or send messages to the server 103, or the vehicle 101 can interact with the server 103 through the network 102 to receive messages or data sent by other users to the server 103. For example, the vehicle 101 regularly sends the power generation parameters of the solar panel (such as light intensity, panel temperature, output current and voltage, etc.) to the server 103 through the network 102, and the server 103 formulates the optimal power supply plan for the vehicle 101 based on these power generation parameters.

[0035] The server 103 may be a business server that provides various services. It should be noted that the server 103 may be hardware or software. When the server 103 is hardware, it may be implemented as a distributed server cluster consisting of multiple servers, or it may be implemented as a single server. When the server 103 is software, it may be implemented as multiple software or software modules (for example, for providing distributed services), or it may be implemented as a single software or software module, which is not specifically limited here.

[0036] Alternatively, the system architecture may not include the server 103. In other words, the server 103 may be an optional device in the embodiments of this specification. That is, the method provided in the embodiments of this specification may be applied to a system structure that only includes the vehicle 101, and the embodiments of this application do not limit this.

[0037] In the embodiment of the present application, the vehicle 101 first determines the conversion power parameters of the electric energy output by the solar panel, and determines the driving power parameters of the electric energy required to drive the vehicle; then, when the conversion power parameters meet the first preset condition between the driving power parameters, the vehicle 101 powers the vehicle through the solar panel; when the conversion power parameters meet the second preset condition between the driving power parameters, the vehicle 101 powers the vehicle through the solar panel and the battery in the vehicle.

[0038] It should be understood that Figure 1 The number of vehicles, networks, and servers in the figure is only illustrative, and any number of vehicles, networks, and servers may be used according to implementation requirements.

[0039] See also Figure 2 , Figure 2This is a schematic flow chart of a vehicle power supply method provided in an embodiment of the present application. The execution subject of the embodiment of the present application can be a vehicle that executes vehicle power supply, a processor in a vehicle that executes the vehicle power supply method, or a vehicle power supply service in a vehicle that executes the vehicle power supply method. For the convenience of description, the specific execution process of the vehicle power supply method is introduced below by taking the execution subject as a processor in a vehicle as an example.

[0040] like Figure 2 As shown, the vehicle power supply method may at least include:

[0041] S202: Determine conversion power parameters of the power output by the solar cell panel, and determine driving power parameters of the power required to drive the vehicle.

[0042] Optionally, in order to achieve efficient use of energy and ensure that the vehicle has a stable and reliable energy supply under various circumstances, a specific energy management algorithm can be used to accurately evaluate the power generation capacity of the solar panels (i.e., the conversion power parameters) and the vehicle's immediate energy needs (i.e., the driving power parameters) in real time, and make reasonable energy allocation decisions based on this.

[0043] Optionally, the conversion power parameters of solar panels refer to the characteristics of the power that can be generated by solar panels under specific lighting conditions, such as the output power of solar panels, the total energy supply, etc., which are important bases for the energy management algorithm to evaluate the energy supply capacity of solar panels. By real-time monitoring of the conversion power parameters of solar panels, the performance of solar panels under different environmental conditions such as light intensity and temperature can be understood, thereby providing key data support for the energy management of vehicles, which helps to determine when solar energy should be used for power supply in priority to maximize the use of renewable energy. In addition, by real-time monitoring and analysis of various parameters of solar panels, potential faults or performance degradation can be discovered in a timely manner. By combining intelligent algorithms for fault warning and diagnosis, measures can be taken in advance to repair or replace them to ensure the long-term stable operation of solar panels.

[0044] Specifically, the vehicle's built-in sensors can monitor key data such as light intensity, output current, voltage and temperature of the solar panels in real time, and determine the power generation parameters of the solar panels based on this, thereby judging the power generation capacity of the solar panels.

[0045] Optionally, current and voltage, as two basic parameters for power transmission, can directly reflect the power generation performance of solar panels. For example, when the output voltage of the solar panel remains stable, the output current directly determines the power generation. The larger the current, the more charge passes through the solar panel per unit time, and thus the more power is generated. Similarly, when the output current of the solar panel remains stable, the level of the output voltage also directly determines the output power. Therefore, the output current and voltage of the solar panel can be monitored in real time by current and voltage sensors to reflect the power generation performance of the solar panel.

[0046] Optionally, light conditions are an important factor in determining the parameters of solar panel conversion of electrical energy. For example, on clear and sunny days, solar panels can efficiently convert solar energy into electrical energy and provide additional power support for the vehicle; however, on cloudy days, rainy days or at night when there is insufficient light, the output power of the solar panel will drop significantly, and may not even be able to provide enough power for the vehicle. Therefore, a light intensity sensor can be installed on the solar panel to monitor the light intensity at different times and under different weather conditions in real time, providing an important basis for subsequent data analysis and algorithm optimization. It should be noted that the light intensity sensor should be arranged on or near the surface of the solar panel to ensure that it can accurately capture the light intensity received by the solar panel.

[0047] Alternatively, the working principle of solar panels is to convert light energy into electrical energy. However, this conversion process is not 100% efficient, and some energy will always be lost in the form of heat energy. Therefore, the temperature of the solar panel is also a key factor affecting the power generation efficiency. As the temperature rises, the power generation efficiency of the solar panel will gradually decrease. Therefore, the temperature sensor can be used to monitor the temperature change of the solar panel in real time, providing a reference for subsequent algorithm adjustment and heat dissipation design. It should be noted that the temperature sensor should be placed on the back or edge of the solar panel to avoid direct exposure to sunlight, which may cause inaccurate temperature measurement.

[0048] Optionally, the driving power parameters of the electric energy required to drive the vehicle refer to the characteristics of the electric energy consumed by the vehicle to maintain normal operation, and are key data for the algorithm to evaluate the vehicle's energy needs. By real-time monitoring and analysis of the driving power parameters of the electric energy required to drive the vehicle, the vehicle's current energy consumption can be understood, and the energy allocation strategy can be flexibly adjusted accordingly to ensure that the vehicle can maintain a stable energy supply under various circumstances. Specifically, the driving power parameters required for the vehicle to maintain normal operation can be calculated based on information such as the vehicle's current speed, load status, driving route prediction, and battery health status, including but not limited to immediate power demand, total energy demand, etc.

[0049] Optionally, the instantaneous power demand refers to the instantaneous power required by the vehicle in the current state (such as acceleration, constant speed, deceleration, etc.). By real-time monitoring and analysis of the instantaneous power demand based on the current speed, acceleration, load state (such as the number of passengers, luggage weight, etc.) and external environmental factors (such as wind speed, road slope, etc.), the distribution of electric energy can be analyzed and controlled more accurately. For example, when the vehicle accelerates, the instantaneous power demand will rise sharply. At this time, it is necessary to ensure that the drive motor can obtain a large electric energy output power in a short time to ensure that the vehicle obtains sufficient power. Since the solar panel is affected by multiple factors such as light intensity and temperature, the instantaneous output power fluctuates greatly, and the battery can quickly respond to the changes in the power demand of the vehicle and provide the required instantaneous power. When the solar panel cannot efficiently output the electric energy required by the drive motor in a short time, it can be selected to provide a relatively efficient instantaneous output power through the battery. When the vehicle ends the acceleration state and resumes constant speed driving, the instantaneous power demand is relatively low, and the solar panel can be switched to power supply.

[0050] Optionally, the total energy demand refers to the total electrical energy required by the vehicle to complete a specific driving task (such as from point A to point B). By combining the driving route, map data (such as road type, etc.), vehicle status (such as driving speed, estimated driving time, etc.) and other information to predict the total energy demand during the entire driving process, the vehicle's endurance can be evaluated and reasonable power supply options can be provided for the vehicle. For example, during long-distance driving, the vehicle's total energy demand is large, while the battery's energy storage capacity is weak. Under good weather and lighting conditions, the solar panels can be used to absorb and convert solar energy to power the drive motor, thereby reducing the consumption of electrical energy in the vehicle's own battery and improving the vehicle's endurance.

[0051] S204: When the converted electric energy parameter satisfies a first preset condition with the driving electric energy parameter, the vehicle is powered by the solar cell panel.

[0052] Optionally, after respectively determining the conversion power parameters of the electric energy output by the solar panel and the driving power parameters of the electric energy required to drive the vehicle, it is necessary to compare the conversion power parameters and the driving power parameters in real time, and based on the relationship between the conversion power parameters and the driving power parameters, determine whether to use the solar panel directly for driving or to switch to other power sources in time to ensure stable operation of the vehicle.

[0053] Specifically, when the conversion power parameters of the electric energy output by the solar panel meet the first preset conditions for the driving power parameters, for example, the instantaneous power of the electric energy output by the solar panel is equal to or much greater than the instantaneous power required by the vehicle, which is sufficient to directly drive the vehicle without the assistance of a battery, then it is automatically possible to automatically choose to use only the solar panel to drive the motor, while storing the remaining electric energy converted by the solar panel in the battery as needed, thereby maximizing the use of renewable energy.

[0054] S206: When the conversion power parameter satisfies a second preset condition with the driving power parameter, the vehicle is powered by the solar panel and the battery in the vehicle.

[0055] Optionally, when the conversion power parameters of the electric energy output by the solar panel do not meet the first preset condition but meet the second preset condition, for example, the electric energy output by the solar panel is not enough to supply power alone, but can meet the total demand of the vehicle after being combined with the battery, then the hybrid power supply mode is entered, and the solar panel and the battery are started at the same time to power the vehicle, so as to ensure that the vehicle obtains a stable power supply.

[0056] In an embodiment of the present application, a vehicle power supply method is provided, which determines the conversion power parameters of the electric energy output by the solar panel, and determines the driving power parameters of the electric energy required to drive the vehicle; when the conversion power parameters meet the first preset condition between the driving power parameters, the vehicle is powered by the solar panel; when the conversion power parameters meet the second preset condition between the driving power parameters, the vehicle is powered by the solar panel and the battery in the vehicle. By determining the conversion power parameters of the electric energy output by the solar panel, the electric energy generated by the solar panel can be obtained, and at the same time, the driving power parameters of the electric energy required to drive the vehicle can be determined, so that the electric energy required by the vehicle under different operating conditions can be accurately evaluated, and accurate data support can be provided for subsequent power supply decisions; when the electric energy generated by the solar panel is sufficient to meet the needs of the vehicle, solar energy is directly used for power supply, which reduces the dependence on traditional energy and reduces the emission of greenhouse gases and the generation of other environmental pollutants; even when the output power of the solar panel is insufficient, the auxiliary power supply of the battery can be used to ensure the normal driving of the vehicle and reduce the risk of driving interruption due to insufficient energy. In this way, through the coordinated power supply of solar panels and batteries, we can directly use solar panels to supply power to achieve efficient energy utilization, and combine it with batteries to supply power when solar energy is insufficient, thereby improving the flexibility of energy utilization and the vehicle's endurance.

[0057] See also Figure 3 , Figure 3 It is a schematic flow chart of a vehicle power supply method provided in an embodiment of the present application.

[0058] like Figure 3 As shown, the vehicle power supply method may at least include:

[0059] S302: Determine conversion power parameters of the power output by the solar cell panel, and determine driving power parameters of the power required to drive the vehicle.

[0060] Specifically, regarding step S302, please refer to the detailed description in step S202, which will not be repeated here.

[0061] S304: When the conversion electric energy parameter is greater than or equal to the driving electric energy parameter, determine a first conversion electric energy in the total electric energy output by the solar cell panel that is equal to the electric energy required to drive the vehicle.

[0062] Optionally, in the vehicle power supply system, the solar panel is an important source of renewable energy, and the electric energy it outputs is often affected by many factors, such as light intensity, temperature, conversion efficiency of the solar panel, etc. Therefore, in the actual operation process, the electric energy output by the solar panel may be equal to or much greater than the electric energy required for the current operation of the vehicle. At this time, it means that the electric energy output by the solar panel is sufficient to supply the electric energy required for the vehicle motor to be driven, and the vehicle can be powered only by the solar panel without the need for additional electric energy from the battery. When the conversion electric energy parameter of the electric energy output by the solar panel is greater than or equal to the driving electric energy parameter, in order to efficiently utilize this part of the electric energy, ensure the stable operation of the vehicle, and maximize the utilization of energy at the same time, it is necessary to comprehensively consider the actual output characteristics of the solar panel and the driving requirements of the vehicle motor, determine the first conversion electric energy in the total electric energy output by the solar panel that is equal to the electric energy required to drive the vehicle, and use this part of the electric energy to power the driving motor, thereby ensuring that the vehicle can obtain a stable and sufficient power supply at any time, and improving the accuracy and stability of the power supply.

[0063] S306: Convert the first converted electric energy into motor driving electric energy used by a motor of the vehicle when driving the vehicle, and power the vehicle through the motor driving electric energy.

[0064] Optionally, the vehicle motor, as a core component for driving the vehicle, has specific specifications and requirements for its demand for electric energy. The rated voltage, rated current, type of electric energy (such as DC or AC) and other parameters of the motor need to match the power supply system to ensure the normal operation and efficient operation of the motor. If the electric energy converted by the solar panel or stored in the battery is directly supplied to the motor, the motor may be damaged due to the mismatch of parameters such as voltage and current, affecting the stable operation of the vehicle. For example, the electric energy converted by the solar panel or stored in the battery is usually direct current (DC), while the electric energy required for the normal operation of some vehicle motors is alternating current (AC). There are significant differences between direct current and alternating current in terms of current direction, voltage waveform, etc. These differences may have adverse effects on the windings, insulation layers and other components of the motor. Based on this, it is necessary to convert the first converted electric energy into an electric energy form that can be directly used by the vehicle motor when driving the vehicle (that is, motor drive electric energy) to ensure a good match between the power supply system and the motor, thereby improving the operating efficiency and stability of the motor.

[0065] Specifically, after the first converted electric energy is determined, this part of the electric energy is converted into motor driving electric energy through a specific power conversion device (such as a DC-AC inverter). For example, direct current is converted into alternating current through a DC-AC inverter, and the output voltage, frequency and other parameters are adjusted as needed to meet the needs of different motors and improve the operating efficiency and stability of the motor, so that the vehicle can be directly powered by the electric energy output by the solar panel.

When the conversion power parameter is greater than the driving power parameter and the vehicle meets a preset charging condition, determine the second conversion power that is not converted into motor driving power in the total power output by the solar panel, and the preset charging condition includes at least one of the vehicle battery status and light intensity.

[0067] Optionally, when the electric energy output by the solar panel is much greater than the electric energy required for the current operation of the vehicle, it means that the electric energy output by the solar panel, in addition to supplying the electric energy for driving the vehicle motor, also has excess electric energy (that is, the second converted electric energy) that is not directly used to drive the vehicle. At this time, in order to improve the energy utilization efficiency of the entire solar panel power supply and make all the electric energy generated by the solar panel effectively utilized, it can be considered to pre-store this part of the second converted electric energy and release it when needed (such as at night or when there is insufficient light) to provide additional power for the vehicle, thereby enhancing the vehicle's endurance.

[0068] Optionally, when the conversion power parameter is greater than the driving power parameter, although it can be determined that there is currently excess power available for charging the battery, if the battery power is already high at this time, continuing to charge may lead to overcharging, thereby accelerating the aging process of the battery and even causing damage to the battery. At the same time, when the light intensity is about to decrease (such as at sunset), the power generation capacity of the solar panel will show a downward trend. At this time, in order to balance the supply and demand of electricity and ensure that the vehicle can still maintain sufficient power when the light is insufficient, it may be given priority to use the remaining electricity to drive the vehicle instead of charging the battery. Based on this, in the case of remaining second conversion power, other preset charging conditions such as the vehicle battery status, light intensity, and vehicle driving status need to be considered. When the preset charging conditions are met, it is determined that the second conversion power that has not been converted into motor drive power in the total power output of the solar panel needs to be stored in the battery.

[0069] Specifically, the remaining power of the battery can be monitored. If the current power of the battery is lower than a preset safety threshold (for example, lower than 80% of the full charge capacity), it is determined that the battery needs to be charged. At this time, even if the vehicle is driving, the excess power generated by the solar panels may be used to charge the battery first to ensure that the battery is in good working condition at all times. At the same time, the health of the battery will also be considered to avoid unnecessary charging operations when the battery is aged or faulty, so as to protect the service life of the battery. Similarly, when the light intensity is high enough to enable the solar panels to continue to generate power in excess of the vehicle's immediate needs, additional charging operations will be considered.

[0070] S310, storing the second converted electric energy in a storage battery; when the converted electric energy parameter satisfies a second preset condition between the driving electric energy parameter, the vehicle is powered by the solar panel and the storage battery in the vehicle.

[0071] Optionally, the output voltage of the solar panel may be different from the voltage of the vehicle battery. Due to this voltage mismatch, if the vehicle battery is charged directly through the second converted electric energy output by the solar panel, it may damage the battery, reduce its service life, and even cause a safety accident. Therefore, in order to ensure the safe and efficient storage of electric energy, it is necessary to use specific power conversion equipment (such as a DC-DC converter) to achieve voltage regulation and matching between the solar panel and the battery.

[0072] Specifically, when the power generated by the solar panel exceeds the vehicle's immediate driving needs and generates the remaining second converted power, the output voltage of the solar panel and the current voltage of the battery are first detected. Once the voltage mismatch between the two is detected, the DC-DC converter will convert the high voltage (or low voltage) output by the solar panel to a voltage level that matches the battery through the internal circuit adjustment mechanism based on the detected solar panel output voltage and battery voltage. After adjustment by the DC-DC converter, the converted power will be safely and stably transmitted to the battery for storage.

[0073] Optionally, when the conversion power parameters of the electric energy output by the solar panel do not meet the first preset condition but meet the second preset condition, for example, the electric energy output by the solar panel is not enough to supply power alone, but can meet the total demand of the vehicle after being combined with the battery, then the hybrid power supply mode is entered, and the solar panel and the battery are started at the same time to power the vehicle, so as to ensure that the vehicle obtains a stable power supply.

[0074] S312: Monitor the maximum power point of the solar panel to determine the circuit parameters corresponding to the maximum power point on the solar panel, where the circuit parameters include at least one of a current parameter and a voltage parameter.

[0075] Alternatively, in a solar power generation system, the performance of solar panels, as key equipment for converting solar energy into electrical energy, directly affects the power generation efficiency of the entire system. However, since its power generation efficiency is affected by many factors, including light intensity, temperature, physical properties of the panels (such as materials, structures), and circuit connection methods, etc. Under different light and temperature conditions, the output current and voltage of the solar panel will change, which will in turn affect its output power.

[0076] Optionally, under specific light and temperature conditions, the solar panel has a specific current and voltage combination that maximizes its output power. The power point corresponding to this current and voltage is called the maximum power point (MPP). At the maximum power point, the solar panel can most efficiently convert solar energy into electrical energy, while working at a non-maximum power point will reduce the power generation efficiency of the solar panel. Based on this, the maximum power point of the solar panel can be monitored, and the circuit parameters corresponding to the solar panel can be adjusted based on the monitoring results so that it always works near the maximum power point to achieve more efficient energy conversion.

[0077] Specifically, a specific maximum power point monitoring algorithm can be used to monitor the output current and voltage of the solar panel in real time, and the output power at different working points can be calculated. On this basis, the point with the maximum output power on the solar panel, i.e., the maximum power point, is found and determined, and the circuit parameters corresponding to the point are recorded, including at least one of the current parameter and the voltage parameter.

[0078] S314: Adjust the circuit parameters of the solar cell panel based on the circuit parameters corresponding to the maximum power point.

[0079] Optionally, after determining the circuit parameters corresponding to the maximum power point, the circuit of the solar panel can be adjusted based on these parameters, which may include changing the connection method of the solar panel (such as series, parallel or mixed), adjusting the values ​​of components such as resistance and capacitance in the circuit, or transforming the output of the solar panel through a converter or other equipment so that it always operates near the maximum power point.

[0080] In an embodiment of the present application, a vehicle power supply method is provided. When the conversion power parameter of the solar panel is greater than or equal to the driving power parameter required for driving the vehicle, it means that the total power output by the solar panel is sufficient to supply the power required for driving the vehicle. At this time, by determining the first conversion power equal to the power required for driving the vehicle from the total power output by the solar panel, the output power of the solar panel is precisely controlled according to the actual power demand of the vehicle; by converting the first conversion power determined above into the motor driving power used by the vehicle motor when driving the vehicle, it is ensured that the first conversion power output by the solar panel can be directly and efficiently converted into power that can be directly used by the driving motor, so that the vehicle can stably obtain the required power and ensure the normal operation of the vehicle. At the same time, when the conversion power parameter is greater than the driving power parameter, it means that the power output by the solar panel exceeds the immediate driving demand of the vehicle. At this time, if the solar panel also meets the preset charging conditions such as the vehicle battery status or light intensity, the solution can store the second conversion power that has not been converted into motor driving power in the battery, which can not only avoid energy waste and improve the energy utilization efficiency of the entire power supply system, but also ensure sufficient power of the battery, provide reliable energy guarantee for the subsequent driving of the vehicle, and improve the vehicle's endurance. In addition, by monitoring the working status of the solar panel, the circuit parameters corresponding to its maximum power point can be accurately captured, and the circuit parameters of the solar panel can be dynamically adjusted according to the parameters, so that it always works near the maximum power point, thereby maximizing the capture and utilization of solar energy and improving the power conversion efficiency.

[0081] See also Figure 4 , Figure 4 It is a schematic flow chart of a vehicle power supply method provided in an embodiment of the present application.

[0082] like Figure 4 As shown, the vehicle power supply method may at least include:

[0083] S402, determining conversion power parameters of the electric energy output by the solar panel, and determining driving power parameters of the electric energy required to drive the vehicle; when the conversion power parameters meet a first preset condition between the driving power parameters, the vehicle is powered by the solar panel.

[0084] Optionally, the conversion power parameters corresponding to the solar panel and the driving power parameters required by the vehicle are monitored in real time. When the conversion power parameters of the power output by the solar panel are greater than or equal to the driving power parameters of the power required to drive the vehicle, the driving motor is charged by the power output by the solar panel. Specifically, for step S402, please refer to the detailed records in steps S202 and S204, which will not be repeated here.

[0085] S404: When the conversion power parameter is less than the driving power parameter and the conversion power parameter is not equal to 0, the total power output by the solar panel and the power stored in the battery are converted into motor driving power used by the vehicle motor when driving the vehicle, and the vehicle is powered by the motor driving power.

[0086] Alternatively, in practical applications, the intensity and duration of solar illumination are affected by many factors such as weather, season, and geographical location. Therefore, the power output of solar panels is often unstable and difficult to continuously meet all the driving needs of the vehicle. Especially in cloudy, rainy, or nighttime conditions with insufficient light, the output power of solar panels will drop significantly, and may even be unable to provide enough power for the vehicle. Based on this, it is possible to consider introducing a hybrid power supply mode through an energy management algorithm. When the output power of the solar panel is insufficient, the battery in the vehicle is used for power supply, thereby ensuring that the vehicle can obtain a stable and sufficient power supply under various lighting conditions. This not only improves the vehicle's endurance, but also enhances its ability to adapt to different environments.

[0087] Optionally, when the conversion power parameter of the electric energy output by the solar panel is less than the driving power parameter and the conversion power parameter is not equal to 0 (that is, the conversion power parameter satisfies the second preset condition), it means that the solar panel is working and generating electric energy, but the electric energy it outputs does not reach all the electric energy required to drive the motor. At this time, a hybrid power supply mode can be adopted. Specifically, the total electric energy output by the solar panel is first collected, and electric energy is extracted from the battery and combined with the electric energy output by the solar panel to form hybrid electric energy. Then it is converted into an electric energy form that can be directly used by the vehicle motor when driving the vehicle (motor drive electric energy), and the vehicle is powered by the motor drive electric energy. In this process, the energy management algorithm will monitor the actual power output of the solar panel and the battery in real time, and dynamically adjust the power supply ratio of the two according to the preset strategy to ensure that the motor can obtain a stable and sufficient power supply.

[0088] S406, monitoring the charge and discharge parameters of the battery during charge and discharge, and determining whether the charge and discharge parameters meet preset charge and discharge conditions; when the charge and discharge parameters do not meet the preset charge and discharge conditions, adjusting the circuit parameters of the battery, the circuit parameters including at least one of the current parameters and the voltage parameters.

[0089] Optionally, as a key component of electric energy storage, the operating state of the battery directly affects the stability and safety of the entire power supply system, and the service life of the battery is closely related to the management of its charging and discharging process. Based on this, in order to ensure the safe operation of the battery, the battery management system can monitor the battery charging and discharging parameters, such as current and voltage, in real time, so that abnormal conditions, such as overcharging, over-discharging or short circuit, can be discovered in time, and the charging and discharging process can be accurately controlled, thereby avoiding potential safety risks and extending the service life of the battery.

[0090] Specifically, the battery management system will set corresponding preset charging and discharging conditions according to the model, specifications and characteristics of the battery use environment. These conditions include but are not limited to the maximum charging current, maximum discharging current, optimal charging voltage range, optimal discharging voltage range and charging and discharging rate. Then, the current and voltage sensors are used to monitor the current and voltage changes of the battery during the charging and discharging process in real time to evaluate the health status and charging and discharging efficiency of the battery. When the battery management system detects that the charging and discharging parameters of the battery do not meet the preset conditions, the adjustment mechanism will be triggered immediately to correct the deviation by adjusting the circuit parameters of the battery. This may include adjusting the output voltage and current of the charger, adjusting the power demand of the drive motor to match the discharge capacity of the battery, or dynamically adjusting the charging and discharging path of the battery through the intelligent circuit control module. For example, if it is detected that the charging current of the battery exceeds the preset maximum charging current, the charging rate may be reduced by reducing the output current of the charger or solar panel to avoid overcharging the battery.

[0091] S408, monitoring multiple power generation parameters on the solar panel, generating power generation information corresponding to the solar panel based on each power generation parameter; triggering a device prompt message based on the power generation information, wherein the device prompt message includes at least one of a voice prompt message and a visual prompt message.

[0092] Optionally, in order to allow the driver to understand key information such as the working status of the solar panel and the actual contribution of solar power to the driving mileage in real time, sensors can be installed at key positions of the solar panel, including but not limited to light intensity sensors, temperature sensors, current sensors and voltage sensors. These sensors can collect data such as the light intensity of the solar panel, the temperature of the panel, and the current and voltage generated in real time, and then transmit the data collected by the sensors to the central processing unit (such as the vehicle controller), so that the central processing unit can perform data preprocessing operations such as cleaning, removing noise and abnormal values ​​on the received data, and determine the current, voltage and other power generation parameters of the solar panel accordingly. Based on these power generation parameters, as well as other characteristic parameters of the solar panel (such as conversion efficiency), the central processing unit can calculate the power generation efficiency of the solar panel, the current power generation, the cumulative power generation, and the actual contribution of solar power to the driving mileage and other power generation information in real time.

[0093] Optionally, based on the power generation information, a device prompt message in the vehicle is triggered, which includes at least one of a voice prompt message and a visual prompt message, so that the driver can understand the working status of the solar panel in real time through this information, and make more reasonable driving decisions. For example, when the power generation efficiency of the solar panel is significantly reduced, a corresponding warning icon or text message can be displayed on the dashboard or central control screen of the vehicle; or the driver can be reminded by a voice prompt "Attention, the power generation efficiency of the solar panel has decreased, please check if there is any obstruction."

[0094] Optionally, drivers can remotely view the power generation information of solar panels through mobile phone software or vehicle management system; detailed power generation reports can also be generated, including daily, weekly and monthly power generation statistics, power generation efficiency analysis and abnormal event records, etc. Drivers can download these reports to conduct in-depth analysis of the operation of solar panels for timely maintenance and optimization.

[0095] In an embodiment of the present application, a vehicle power supply method is provided, which provides stable energy support for the vehicle when the light is insufficient or the solar panel output power is limited by combining the dual power supply capabilities of the solar panel and the battery. When the conversion power parameter output by the solar panel is less than the power parameter required for the vehicle to drive, but there is still a certain output, it is combined with the power stored in the battery and converted into the motor drive power used by the vehicle motor when driving the vehicle to meet the driving needs of the vehicle. This hybrid power supply mode not only improves the comprehensive utilization efficiency of energy, but also enhances the flexibility and adaptability of the vehicle power supply system. At the same time, by monitoring the charge and discharge parameters of the battery during the charge and discharge process, and comparing these parameters with the preset charge and discharge conditions, it is determined whether the working state of the battery deviates from the preset safety range. When the abnormal charge and discharge state of the battery is monitored, such as overcharge or over discharge, by dynamically adjusting the circuit parameters of the battery, it can ensure that the battery is charged and discharged under appropriate conditions, prevent the battery from being damaged due to excessive charge and discharge, thereby extending the service life of the battery and reducing the maintenance cost of the user. In addition, real-time monitoring of multiple power generation parameters on solar panels can accurately capture the working status of solar panels and generate detailed power generation information, which helps operation and maintenance personnel to timely understand equipment performance, predict potential failures, and provide data support for refined energy management. At the same time, device prompt messages triggered by these real-time information can ensure that drivers or managers receive key information at the first time, such as sufficient power, reduced charging efficiency, or maintenance required, thereby achieving instant response and efficient processing of the power generation status of solar panels.
