[0002] Driven by both energy transformation and environmental protection policies, the new energy vehicle industry, especially the electric vehicle industry, has developed rapidly. However, as its popularity increases, the vehicle's range and the convenience and timeliness of charging and replenishing energy have increasingly become core concerns for users. Especially during the peak electricity consumption seasons of winter and summer, the "range anxiety" problem faced by electric vehicles has become increasingly prominent, seriously restricting users' driving experience and confidence in use. Currently, power battery technology faces a bottleneck in increasing energy density. At the same time, problems such as the relatively lagging construction of charging infrastructure, the shortage of public charging resources, and long charging times are common. In this context, how to efficiently utilize inexhaustible solar energy resources and develop a solution that can be deeply integrated with vehicles and provide continuous energy replenishment has become a key technical direction for alleviating or even solving electric vehicle range anxiety and optimizing vehicle energy utilization efficiency. Summary of the Invention

[0006] Preferably, the determination of whether the start threshold is reached based on the environmental parameters and the real-time vehicle status parameters to obtain the judgment result is specifically: When the vehicle's power battery state of charge is lower than 60%, or the local / network solar charging enable signal flag is fault-free, the on-board solar charging system performs a functional self-check to see if there is a fault. If there is a fault, it enters a fault state. If not, it determines whether the ambient temperature, solar radiation intensity and solar radiation time meet the preset thresholds. If so, it enters a normal state; if not, it enters a waiting state.

[0009] Preferably, when the judgment result is a waiting state, when the ambient temperature, solar radiation intensity and solar radiation time during the waiting period meet preset thresholds, the judgment result is changed to a normal state.

[0010] In a second aspect, the present invention provides a vehicle-mounted solar charging control system, comprising: Data acquisition and analysis module, used to obtain environmental parameters and real-time vehicle status parameters; The solar charging control module is used to determine whether the start threshold is reached based on environmental parameters and real-time vehicle status parameters, and obtain a judgment result; The solar energy conversion module is used to connect to the vehicle's power battery system and enable or disable the solar charging mode based on the judgment result.

DETAILED DESCRIPTION

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0017] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise indicated, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present invention.

[0018] See also Figure 1 , this application discloses a vehicle-mounted solar charging control method, comprising: S1: Obtain environmental parameters and vehicle real-time status parameters; S2: Determine whether the start threshold is reached based on environmental parameters and real-time vehicle status parameters, and obtain a judgment result; S3: Turn on or off the solar charging mode according to the judgment result.

[0019] By dynamically and collaboratively determining environmental parameters and the vehicle's real-time status, the on-board solar charging system achieves intelligent and precise start-stopping. When solar radiation conditions are sufficient and the vehicle is off-grid, this solution proactively converts solar energy into effective range, significantly alleviating range anxiety for new energy vehicles. Furthermore, through a threshold control mechanism, ineffective or high-risk charging scenarios (such as low temperature or low light conditions) are avoided, improving energy efficiency while ensuring battery safety. This ultimately creates a "no-touch range extension" user experience, significantly enhancing the ability of electric vehicles to operate continuously in environments without charging facilities, and providing a sustainable solution for new energy vehicle energy systems.

[0020] In some embodiments, the environmental parameters and real-time vehicle status parameters include ambient temperature, solar radiation intensity, solar radiation duration, and the vehicle's power battery state of charge. Because the maximum power point of the photovoltaic panels mounted on the roof changes constantly with changes in ambient temperature and solar radiation intensity, when the ambient temperature, solar radiation intensity, and solar radiation duration reach system activation thresholds, the photovoltaic panels enter photoelectric conversion and reach a unique maximum power output point.

[0021] In some embodiments, see Figure 2 , the determination of whether the start threshold is reached based on the environmental parameters and the real-time status parameters of the vehicle is performed, and the determination result is obtained, specifically: When the vehicle's power battery state of charge is lower than 60%, or the local / network solar charging enable signal flag is fault-free, the on-board solar charging system performs a functional self-check to see if there is a fault. If there is a fault, it enters a fault state. If not, it determines whether the ambient temperature, solar radiation intensity and solar radiation time meet the preset thresholds. If so, it enters a normal state; if not, it enters a waiting state.

[0022] Further preferably, when the judgment result is a fault state or a waiting state, the solar charging mode is not turned on; when the judgment result is a normal state, the solar charging mode is turned on.

[0023] Further preferably, the preset thresholds are: ambient temperature in the range of 0-45°C; solar radiation intensity in the range of 100-200W / m 2 Within the scope; solar radiation time is not less than 20 minutes.

[0024] In some embodiments, when the judgment result is a waiting state, when the ambient temperature, solar radiation intensity, and solar radiation time during the waiting period meet preset thresholds, the judgment result is changed to a normal state.

[0025] In some embodiments, see Figure 2 , the determination of whether the start threshold is reached based on the environmental parameters and the real-time status parameters of the vehicle is performed, and the determination result is obtained, specifically: (1) When the power battery SoC is lower than 60% or the local / network solar charging enable signal (Enable_SolarChar) flag is "1", the on-board solar charging system performs a functional self-test. If the self-test status flag is "0" (fault), it reports "Fail_SolarSystem" to the solar charging control module and stops executing the solar charging action; (2) When the power battery SoC is lower than 60% or the local / network solar charging enable signal (Enable_SolarChar) flag is "1", the on-board solar charging system performs a functional self-test. If the self-test status flag is "1" (no fault), it continues to judge the starting conditions such as ambient temperature and solar radiation intensity: (2-1) When the ambient temperature meets the start-up threshold A, and the solar radiation intensity meets the threshold B, and the solar radiation duration is ≥20 minutes, the solar photovoltaic conversion function is started; the solar charging control module will send a solar charging wake-up "SolarChar_Wakup" signal to the VCU, BMS and GW controllers, and report the "Start_SolarChar" status to the VCU. After receiving it, the VCU sends the "SolarChar_Request" command to the BMS. The BMS simultaneously performs pre-charging and closes the high-voltage relay, and the vehicle enters the normal solar charging process; (2-2) When the ambient temperature does not meet the start-up threshold A, or the solar radiation intensity does not meet the threshold B, or the solar radiation duration is less than 20 minutes, the solar charging system maintains real-time monitoring status; and reports the "Monitor_SolarChar" status to the VCU. After receiving it, the VCU sends the "SolarChar_RequestPause" command to the BMS. After completing the self-test, the BMS enters the waiting state and reports the "Battery_Waiting" status to the VCU. When the solar charging system meets the charging conditions, the vehicle enters the normal solar charging process according to the charging strategy (2-1) above. (3) When any one or more of the three conditions of ambient temperature, solar radiation intensity, or solar radiation time are not met during the solar charging process of (2-1), the solar charging control module will immediately stop sending the solar charging wake-up "SolarChar_Wakup" signal, stop waking up the VCU, BMS and GW controllers, and the solar charging system enters the "SolarChar_Standby" state. If the above fault conditions are restored to normal within 10 minutes (including 10 minutes), the fault self-recovery counter (Failt-Counter) is cleared to "0", and the solar charging system can recover by itself and send the solar charging wake-up "SolarChar_Wakup" signal to the VCU, BMS and GW controllers again, and report the "Start_SolarChar" state to the VCU. After receiving it, the VCU sends the "S SolarChar_Request" instruction is sent to BMS, and BMS simultaneously performs pre-charging and closes the high-voltage relay, and the vehicle enters the normal solar charging process; if the above fault condition lasts for more than 10 minutes, the fault self-recovery counter (Failt-Counter) keeps counting to "1", the solar charging system is automatically shut down, and no longer monitors whether the solar charging condition is restored. The entire system is in a dormant state. At the same time, the system exits the solar charging state and jumps the local / network solar charging enable signal (Enable_SolarChar) to (Disable_SolarChar). When the vehicle again passes the local / network solar charging enable signal (Enable_SolarChar) flag position to "1", or after power is turned on and off again, the solar charging system can execute the charging processes corresponding to the above (2-1) and (2-2).

[0026] This application also discloses a vehicle-mounted solar charging control system, comprising: Data acquisition and analysis module, used to obtain environmental parameters and real-time vehicle status parameters; The solar charging control module is used to determine whether the start threshold is reached based on environmental parameters and real-time vehicle status parameters, and obtain a judgment result; The solar energy conversion module is used to connect to the vehicle's power battery system and enable or disable the solar charging mode based on the judgment result.

[0027] In some embodiments, the present invention provides a vehicle-mounted solar charging control system, which mainly includes: a data acquisition and analysis module, a solar charging control module (such as an MPPT photovoltaic charging controller in the vehicle body area) and a solar energy conversion module (including a photovoltaic roof).

[0028] The data acquisition and analysis module is mainly used to realize two-way intelligent interaction between the vehicle and the on-board solar charging system, and real-time intelligent detection of the working status of the on-board solar charging system (ambient temperature, solar radiation intensity, solar radiation time and vehicle power battery charge state).

[0029] The solar charging control module controls the solar energy conversion module to perform solar energy photoelectric conversion to charge the vehicle power battery system when the vehicle power battery system meets the solar energy charging conditions according to the control instructions sent by the data acquisition and analysis module; The solar energy conversion module is used to connect to the power battery system of the vehicle and, under the control of the solar charging control module, perform photoelectric conversion and high-low voltage conversion to replenish and charge the power battery system.

[0030] A vehicle-mounted solar charging control system Figure 3 As shown, it mainly includes a data acquisition and analysis module, a solar charging control module (such as the MPPT photovoltaic charging controller in the vehicle body area) and a solar energy conversion module (including a photovoltaic roof).

[0031] The data acquisition and analysis module uses a dedicated data collector to dynamically and real-time collect and monitor the ambient temperature, solar radiation intensity, solar radiation time and vehicle charging status corresponding to the on-board solar charging system, realize two-way intelligent interaction between the on-board solar charging system and the vehicle, and provide reasonable and effective sampling data for the solar charging control module.

[0032] The solar charging control module includes an MPPT photovoltaic controller in the vehicle area and a charging controller that interacts with the entire vehicle. By quickly and accurately tracking the maximum power point of the photovoltaic panels mounted on the roof and dynamically interacting with the vehicle's high-voltage charging system, it controls the onboard solar charging system to charge the power battery. When the vehicle's power battery system meets the solar charging conditions, the solar conversion module is controlled based on the sampled and analyzed data sent by the data acquisition and analysis module to perform solar photovoltaic conversion and replenish energy for the vehicle's power battery system. Since the maximum power output point of the photovoltaic panels mounted on the roof changes with the ambient temperature and solar radiation intensity, when the ambient temperature, solar radiation intensity and solar radiation time reach the system startup threshold, the photovoltaic panels enter the photoelectric conversion and reach a unique maximum power output point; The solar energy conversion module is used to connect to the vehicle's power battery system and, under the control of the solar charging control module, uses an MPPT (Maximum Power Point Tracking) maximum power controller to ensure that the photovoltaic panels always operate at the maximum power point, thereby improving the photovoltaic panel's photoelectric conversion efficiency. Under the action of the vehicle's interactive charging controller, the module performs high-to-low voltage DC-DC conversion to replenish and charge the power battery system. Controlling the operating state of the solar charging conversion module according to the charging control instruction, and controlling the operating state of the solar charging conversion module according to the operating environment information of the vehicle-mounted solar charging system when the operating state of the power battery system of the vehicle meets the solar charging conditions; In some embodiments, when the vehicle power battery system status meets the solar charging conditions, a charging control instruction is sent to the vehicle-mounted solar charging control module through the data acquisition and analysis module; Specifically, the data acquisition and analysis module uses a dedicated temperature sensor and light intensity sensor, combined with a high-precision linear amplifier circuit, to dynamically acquire the ambient temperature, solar radiation intensity, and radiation time in real time. After sampling, amplification, and filtering, the data is output to the solar charging control module: (1) When the power battery SoC is lower than 60% or the local / network solar charging enable signal (Enable_SolarChar) flag is "1", the on-board solar charging system performs a functional self-test. If the self-test status flag is "0" (fault), it reports "Fail_SolarSystem" to the solar charging control module and stops executing the solar charging action; (2) When the power battery SoC is lower than 60% or the local / network solar charging enable signal (Enable_SolarChar) flag is "1", the on-board solar charging system performs a functional self-test. If the self-test status flag is "1" (no fault), it continues to judge the starting conditions such as ambient temperature and solar radiation intensity: (2-1) When the ambient temperature meets the start-up threshold A, and the solar radiation intensity meets the threshold B, and the solar radiation duration is ≥20 minutes, the solar photovoltaic conversion function is started; the solar charging control module will send a solar charging wake-up "SolarChar_Wakup" signal to the VCU, BMS and GW controllers, and report the "Start_SolarChar" status to the VCU. After receiving it, the VCU sends the "SolarChar_Request" command to the BMS. The BMS simultaneously performs pre-charging and closes the high-voltage relay, and the vehicle enters the normal solar charging process; (2-2) When the ambient temperature does not meet the start-up threshold A, or the solar radiation intensity does not meet the threshold B, or the solar radiation duration is less than 20 minutes, the solar charging system maintains real-time monitoring status; and reports the "Monitor_SolarChar" status to the VCU. After receiving it, the VCU sends the "SolarChar_RequestPause" command to the BMS. After completing the self-test, the BMS enters the waiting state and reports the "Battery_Waiting" status to the VCU. When the solar charging system meets the charging conditions, the vehicle enters the normal solar charging process according to the charging strategy (2-1) above. (3) When any one or more of the three conditions of ambient temperature, solar radiation intensity, or solar radiation time are not met during the solar charging process of (2-1), the solar charging control module will immediately stop sending the solar charging wake-up "SolarChar_Wakup" signal, stop waking up the VCU, BMS and GW controllers, and the solar charging system enters the "SolarChar_Standby" state. If the above fault conditions are restored to normal within 10 minutes (including 10 minutes), the fault self-recovery counter (Failt-Counter) is cleared to "0", and the solar charging system can recover by itself and send the solar charging wake-up "SolarChar_Wakup" signal to the VCU, BMS and GW controllers again, and report the "Start_SolarChar" state to the VCU. After receiving it, the VCU sends the "S SolarChar_Request" instruction is sent to BMS, and BMS simultaneously performs pre-charging and closes the high-voltage relay, and the vehicle enters the normal solar charging process; if the above fault condition lasts for more than 10 minutes, the fault self-recovery counter (Failt-Counter) keeps counting to "1", the solar charging system is automatically shut down, and no longer monitors whether the solar charging condition is restored. The entire system is in a dormant state. At the same time, the system exits the solar charging state and jumps the local / network solar charging enable signal (Enable_SolarChar) to (Disable_SolarChar). When the vehicle again passes the local / network solar charging enable signal (Enable_SolarChar) flag position to "1", or after power is turned on and off again, the solar charging system can execute the charging processes corresponding to the above (2-1) and (2-2).

[0033] An on-board solar charging system and control method provided by an embodiment of the present invention can effectively improve the range anxiety problem of new energy electric vehicles, especially when the solar radiation intensity and solar radiation time are sufficient and there is no charging and energy replenishment equipment to charge and replenish the vehicle's power battery.
