Description

Technical Field

[0002] With the development of the times, electric vehicle technology has made great progress, and all indicators of the system can meet the needs of most consumers. However, anxiety about battery life is still the number one worry for R&D personnel and consumers. At present, the process of improving the energy density of power batteries is relatively slow and the cycle is longer than that of improving system efficiency, which directly limits the ultimate upper limit of battery life. Therefore, in order to further increase battery life, reliable solar power generation and thin and light solar panels have attracted much attention, and manufacturers have successively launched electric vehicles with solar power generation functions.

[0003] However, due to the limited space on the roof, the area of ​​the solar panels is limited, and the power generation is seriously insufficient. The existing solution is to fix multiple solar panels in a matrix on a framed rack, which is fixed to the roof of the vehicle in a detachable manner, wherein a support mechanism is used on both sides of the rack to perform a separate lifting action, so that the tilt angle of the solar panel is in real time facing the light at the current moment, thereby increasing the power generation. However, this solution mainly considers the impact of solar light angles at different times of the day, and does not consider the impact of vehicle speed, wind speed and wind direction on solar panel power generation during driving.

[0004] Therefore, a new type of roof solar control system and control method thereof and vehicle are needed to solve the above technical problems. Summary of the invention

[0033] The following is a detailed description of the roof solar control system and control method and vehicle of some embodiments of the present invention in conjunction with the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other if there is no conflict.

[0034] In one embodiment of the present invention, the present invention provides a control method for a rooftop solar energy system. The solar energy system includes a solar panel, the solar panel includes a first panel and a second panel, and the first panel is movably arranged above the second panel. Exemplarily, the solar energy system may also include a swing rod, a conductive sliding rod, a conductive sliding rail, a retractable support rod, a roof frame, etc., which are used to cooperate with each other to achieve the movement of the first panel relative to the second panel. It should be understood that the solar energy system may also include other components, such as a memory and a processor, etc., which will not be described in detail here for the sake of brevity.

[0035] refer to Figure 1-3 , Figure 1-3 Schematic diagram of a roof structure of a roof solar system according to an embodiment of the present invention in different states.

[0036] in, Figure 1 The first solar panel 11 is in a first position relative to the second solar panel 12, and the second solar panel 12 can be fixed on the roof. At this time, the first solar panel 11 is stacked on the second solar panel 12, and the second solar panel 12 is completely (or almost completely) blocked by the first solar panel 11. There is no (or almost no) sunlight shining on the second solar panel 12. The second solar panel 12 cannot generate electricity or generates very little electricity, and only the first solar panel 11 can generate electricity.

[0037] Figure 2 The first battery panel 11 is at a second position relative to the second battery panel 12, at which time the center of the first battery panel 11 is at a first distance from the second battery panel 12 in the first direction, and is less than a predetermined distance from the center of the second battery panel 12 in the second direction. The first direction may be a vertical direction, and the second direction may be a horizontal direction, that is, at this time, the first battery panel 11 is lifted upward relative to the second battery panel 12 but does not move in the horizontal direction, so that there is a certain distance between the first battery panel 11 and the second battery panel 12 in the vertical direction, so that the first battery panel 11 can generate electricity under full sunlight, and the second battery panel 12 can generate a small amount of electricity under a small amount of sunlight.

[0038] Exemplarily, the first distance can be set to any suitable distance as needed, such as 4 cm, 6 cm, 10 cm, 15 cm, etc., and the present invention is not limited to this.

[0039] Exemplarily, the predetermined distance may be zero, that is, the first battery panel 11 and the second battery panel 12 completely overlap, and may also be set as required, for example, to 0.5 cm, 1 cm, etc.

[0040] Exemplarily, the first solar panel 11 can be switched from the first position to the second position relative to the second solar panel 12 by swinging the swing rod 13 from the horizontal position to the vertical position. Exemplarily, the swing rod 13 can be a retractable swing rod. In this case, after the swing rod 13 swings to the vertical position, the first distance can be increased by stretching the swing rod, that is, the first solar panel 11 is farther from the second solar panel 12, so that the second solar panel 12 is exposed to more light and can generate more electricity.

[0041] Figure 3 The first battery panel 11 is at a third position relative to the second battery panel 12. At this time, the center of the first battery panel 11 is at a first distance from the second battery panel 12 in the first direction, and is at a second distance from the center of the second battery panel 12 in the second direction. The second distance is greater than or equal to a predetermined distance, that is, at this time, the first battery panel 11 is lifted upward relative to the second battery panel 12 and moves in the horizontal direction, so that there is a certain distance between the first battery panel 11 and the second battery panel 12 in both the vertical direction and the horizontal direction, so that the first battery panel 11 can generate electricity under full sunlight, and the second battery panel 12 can also be partially or fully illuminated, so that more electricity can be generated.

[0042] Exemplarily, the second distance may be automatically adjusted according to the wind force, and may also be automatically adjusted according to other factors, such as the distance to other vehicles, etc., which is not limited in the present invention.

[0043] Exemplarily, the horizontal movement of the first battery panel 11 relative to the second battery panel 12 may be achieved by, for example, a conductive sliding rod and a conductive sliding rail, which is not limited in the present invention.

[0044] For example, when the first battery panel 11 moves horizontally relative to the second battery panel 12, the retractable support rod 14 can be extended so that the first battery panel 11 is supported to the ground by the retractable support rod 14 to improve the structural stability of the first battery panel 11. When the first battery panel 11 moves a portion of the horizontal direction relative to the second battery panel 12, if the wind force is small at this time, the retractable support rod may not be used for support. When the first battery panel 11 moves to the maximum amount relative to the second battery panel 12 in the horizontal direction, the retractable support rod may be used for support.

[0045] Exemplarily, the inclination of the first solar panel 11 can be adjusted by adjusting the height of the retractable support rod 14 so that the direction of the first solar panel 11 follows the direction of sunlight, thereby maximizing the power generation of the first solar panel 11 and maximizing the solar power generation of the entire vehicle.

[0046] In one embodiment, in order to increase the power generation of the second solar panel 12 , a coating with good reflective effect may be applied to the lower surface of the first solar panel 11 .

[0047] refer to Figure 4 , Figure 4 is a flowchart of an exemplary control method 400 of a rooftop solar energy system according to an embodiment of the present invention; Figure 5 is a flowchart of an exemplary control method of a rooftop solar energy system when a vehicle is in a driving state according to an embodiment of the present invention; Figure 6 The figure is a flowchart of an exemplary control method of a rooftop solar energy system when a vehicle is in a parking state according to an embodiment of the present invention. The solar energy system includes a solar cell panel, and the solar cell panel includes a first cell panel 11 and a second cell panel 12. The first cell panel 11 is movably disposed above the second cell panel 12.

[0048] like Figure 4 As shown, the control method 400 may include the following steps:

[0049] In step 410, the driving speed of the vehicle where the solar panel is located and the wind parameters of the wind around the vehicle are obtained; and

[0050] In step 420 , the position of the first solar panel 11 relative to the second solar panel 12 is controlled based on the driving speed of the vehicle and the wind parameter of the wind.

[0051] For example, the driving speed of the vehicle can be obtained by a speedometer on board the vehicle.

[0052] Exemplarily, the wind parameters of the wind around the vehicle may include wind speed, wind direction, wind force, etc. Exemplarily, the wind parameters may be acquired using any suitable sensor, such as a speed sensor, a direction sensor, a force sensor, etc.

[0053] In one embodiment, in order to prevent the vehicle from rolling over, the control of the position of the first solar panel 11 relative to the second solar panel 12 based on the vehicle's driving speed and the wind parameters in step 420 may include: when the vehicle's driving speed is greater than or equal to a preset vehicle speed threshold, controlling the first solar panel 11 to be in the first position relative to the second solar panel 12. Specifically, if the first solar panel 11 is originally in the first position, the first solar panel 11 is not lifted at this time, but is locked; in addition, if the vehicle's driving speed is low, the first solar panel 11 of the vehicle has been lifted and is in the second position or the third position, then if the vehicle's driving speed is greater than or equal to the preset value, the lifted first solar panel 11 will automatically drop back to the first position to prevent the vehicle from rolling over.

[0054] For example, the speed threshold may be a default value (eg, 80 km / h), or may be pre-set by the user as required, which is not limited in the present invention. For example, based on safety considerations, when the user sets the speed threshold, the set speed threshold cannot be higher than the default value.

[0055] like Figure 5 As shown, in one embodiment, in order to prevent the vehicle from rolling over, the control of the position of the first solar panel 11 relative to the second solar panel 12 based on the vehicle's driving speed and the wind parameters in step 420 may include: when the wind speed around the vehicle is greater than or equal to a preset wind speed threshold, controlling the first solar panel 11 to be in the first position relative to the second solar panel 12. Specifically, if the first solar panel 11 is originally in the first position, the first solar panel 11 is not lifted at this time, but is locked; in addition, if the first solar panel 11 of the vehicle has been lifted and is in the second position or the third position when the wind speed is low, then if the wind speed is greater than or equal to the preset value, the lifted first solar panel 11 will automatically drop back to the first position to prevent the vehicle from rolling over.

[0056] Exemplarily, the wind speed threshold may be a default value (eg, 10 m / s), or may be pre-set by the user as required, which is not limited in the present invention. Exemplarily, based on safety considerations, when the user sets the wind speed threshold, the set wind speed threshold cannot be higher than the default value.

[0057] In one embodiment, in order to prevent the vehicle from being in danger, controlling the position of the first solar panel 11 relative to the second solar panel 12 based on the vehicle's driving speed and the wind parameters in step 420 may include: when the vehicle's driving speed is less than a preset vehicle speed threshold and the wind speed is less than a preset wind speed threshold, controlling the position of the first solar panel 11 relative to the second solar panel 12 based on the wind force exerted on the vehicle when the first solar panel 11 is in the second position relative to the second solar panel 12.

[0058] Exemplarily, the wind force exerted on the vehicle may include a first wind force and a second wind force, wherein the first wind force may be the force exerted on the side of the entire vehicle, and the second wind force may be the upward force exerted on the first solar panel 11 in the vertical direction when the first solar panel 11 is in the second position relative to the second solar panel 12.

[0059] In one embodiment, controlling the position of the first solar panel 11 relative to the second solar panel 12 based on the wind force exerted on the vehicle when the first solar panel 11 is in the second position relative to the second solar panel 12 may include the following steps:

[0060] Calculating a first wind force and a second wind force exerted by the wind on the vehicle based on the wind speed, the wind direction, and the driving speed of the vehicle; and

[0061] When the first wind force is greater than or equal to a preset first wind force threshold and / or the second wind force is greater than or equal to a preset second wind force threshold, the first solar panel 11 is controlled to be in a first position relative to the second solar panel 12 .

[0062] When the first wind force is greater than or equal to the preset first wind force threshold, the vehicle is at risk of rolling over, so the first battery panel 11 is controlled to be in the first position relative to the second battery panel 12. Specifically, if the first battery panel 11 is originally in the first position, the first battery panel 11 is not lifted at this time; in addition, if the first wind force is relatively small, the first battery panel 11 of the vehicle has been lifted and is in the second position or the third position, then if the first wind force is greater than or equal to the preset first wind force threshold, the lifted first battery panel 11 will automatically drop back to the first position to prevent the vehicle from rolling over.

[0063] When the second wind force is greater than or equal to the preset second wind force threshold, the first battery panel 11 is at risk of being overturned, so the first battery panel 11 is controlled to be in the first position relative to the second battery panel 12. Specifically, if the first battery panel 11 is originally in the first position, the first battery panel 11 is not lifted at this time; in addition, if the first battery panel 11 of the vehicle has been lifted and is in the second position or the third position when the second wind force is relatively small, then if the second wind force is greater than or equal to the preset second wind force threshold, the lifted first battery panel 11 will automatically drop back to the first position to prevent the first battery panel 11 from being overturned.

[0064] Exemplarily, the first wind force threshold and the second wind force threshold may be default values ​​(for example, the first wind force threshold is 10000N, etc., and the second wind force threshold is 3000N, etc.), or may be pre-set by the user as required, which is not limited in the present invention. Exemplarily, based on safety considerations, when the user sets the first wind force threshold and the second wind force threshold, the set wind force threshold cannot be higher than the default value.

[0065] In one embodiment, the control method may further include the following steps:

[0066] When the first wind force is less than the first wind force threshold and the second wind force is less than the second wind force threshold, based on the wind speed, wind direction and driving speed of the vehicle, the increased power loss of the first battery panel 11 when it is in the second position relative to the second battery panel 12 compared to when it is in the first position is calculated, and the increased power generation of the first battery panel 11 when it is in the second position relative to the second battery panel 12 compared to when it is in the first position is calculated; and

[0067] The increased power generation is compared with the increased power loss, and the position of the first solar panel 11 relative to the second solar panel 12 is controlled based on the result of the comparison.

[0068] In one embodiment, controlling the position of the first solar panel 11 relative to the second solar panel 12 based on the comparison result may include the following steps:

[0069] When the increased power generation is less than or equal to the increased power loss, controlling the first battery panel 11 to be in a first position relative to the second battery panel 12; and

[0070] When the increased power generation is greater than the increased power loss, the first battery panel 11 is controlled to be in the second position relative to the second battery panel 12. Specifically, when the increased power generation is less than or equal to the increased power loss, if the first battery panel 11 is originally in the first position, the first battery panel 11 is not lifted at this time.

[0071] In one embodiment, the control method may further include: when the first solar panel 11 is in the second position relative to the second solar panel 12 , controlling to change the inclination of the first solar panel 11 relative to the second solar panel 12 to increase the illumination area of ​​the first solar panel 11 .

[0072] Exemplarily, the inclination of the first battery panel 11 relative to the second battery panel 12 can be changed by controlling the swing rod 13, for example, the inclination of the first battery panel 11 relative to the second battery panel 12 can be changed by controlling the height of the swing rods on both sides of the battery panel. Exemplarily, controlling the height of the swing rods 13 on both sides of the battery panel may include, for example, the swing rod 13 on one side of the battery panel is erected (i.e., in a vertical position), and the swing rod 13 on the other side is not erected (i.e., in a horizontal position), or the swing rod 13 on one side of the battery panel is erected but not elongated, and the swing rod 13 on the other side is erected and elongated, or the swing rods 13 on both sides of the battery panel are erected and elongated, but the elongated lengths are different, etc.

[0073] like Figure 6 As shown, in one embodiment, the control method may further include the following steps:

[0074] When the vehicle is in a parked state, calculating various wind forces exerted on the vehicle in various directions when the first solar panel 11 is in the second position or the third position relative to the second solar panel 12 based on the wind speed and wind direction; and
