Detailed Description
Those skilled in the art understand that, as background, existing automotive energy management solutions are still at a low level of utilization of solar energy resources. For example, in order to not change the layout of the entire vehicle, the conventional vehicle energy management system generally uses solar energy resources by connecting a solar panel and a storage battery. According to the scheme, although the solar energy resource can be fully utilized during the running of the automobile, when the automobile is in a parking state, the solar battery is started to charge the storage battery only when the electric quantity of the storage battery is insufficient. In the driving process of a common automobile before parking, the electric quantity of the storage battery is maintained at a high level through the generator, more oil consumption is generated in the process, the solar battery after parking is directly useless, and the utilization rate of the solar battery is reduced.
In order to solve the technical problem, an embodiment of the invention provides an automobile energy management system, which comprises a photovoltaic control unit and an entire automobile control unit, wherein the photovoltaic control unit is connected with a solar cell unit and a storage battery unit, and the entire automobile control unit is connected with a generator unit and the storage battery unit. In the technical scheme of this embodiment, when the car is in a driving state and the electric quantity of battery unit is less than preset threshold value, photovoltaic control unit control solar cell unit to battery unit charges, and whole car control unit control generator unit to battery unit charges or stops charging.
The technical scheme of the embodiment of the invention combines different application scenes, and reasonably distributes the power output of the storage battery unit, the generator unit and the solar battery unit through the photovoltaic control unit and the whole vehicle control unit, so that when the vehicle is in a driving state, the electric quantity of the storage battery unit can be maintained at a normal level (for example, the electric quantity level between 100% electric quantity and critical electric quantity at which storage battery feeding can occur) to reduce the load of the generator and further save oil; when the automobile is in a parking state, the solar cell unit is utilized to gradually fill the electric quantity of the storage battery unit from the normal level (for example, a preset threshold value predetermined by the technical scheme of the embodiment of the invention) so as to better avoid the storage battery feeding phenomenon caused by long-term idling of the automobile, and therefore, the solar energy utilization rate of the automobile is more effectively improved on the premise of not changing the layout of the whole automobile and not increasing an additional energy storage device. Further, when the car is in the parking state, can also be according to the start-stop of factors such as battery unit's electric quantity state and whole car environmental conditions control photovoltaic extension load to optimize the user driving comfort of car under the parking state and experience, for example, can drive travelling comfort extension functions such as whole car ventilation, seat semiconductor refrigeration and rear-view mirror heating of car through solar cell drive.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a schematic structural diagram of an automotive energy management system according to a first embodiment of the present invention.
Specifically, the vehicle energy management system 1 may include a photovoltaic control unit 500, the photovoltaic control unit 500 is connected to the solar cell unit 300 and the storage cell unit 200, and when the vehicle is in a driving state and the electric quantity of the storage cell unit 200 is lower than a preset threshold value, the photovoltaic control unit 500 controls the solar cell unit 300 to charge the storage cell unit 200.
Preferably, the Charge of the battery cell 200 may be characterized by a State of Charge (SOC) value, which may be expressed in percentage form, for example, the Charge of the battery cell 200 may have a value range of [ 0%, 100% ] or [0,1 ]. Preferably, when the charge SOC of the battery unit 200 is 0 or 0%, it indicates that the battery included in the battery unit 200 is completely discharged; when the charge SOC of the battery cell 200 is 1 or the charge SOC is 100%, it indicates that the battery included in the battery cell 200 is fully charged.
Preferably, the preset threshold may be a power amount of a battery included in the battery unit 200 at a normal level, wherein the normal level may mean that the battery itself is not fed and power is supplied to the outside with a surplus power. Those skilled in the art understand that the technical solution of the embodiment of the present invention may improve the utilization rate of solar energy by using the preset threshold, for example, the preset threshold may be SOC equal to 90%, and for an automobile in a driving state, when the SOC value of the battery unit 200 is lower than 90%, the solar battery unit 300 is controlled to charge the battery unit 200; when the SOC of the battery unit 200 reaches 90%, the solar cell 300 may be controlled to temporarily stop charging the battery unit 200, and if the electric energy stored in the battery unit 200 is consumed and the electric quantity thereof is less than 90% during the following driving, the solar cell 300 may be controlled to charge the battery unit 200.
Those skilled in the art understand that, in the technical solution of the embodiment of the present invention, the preset threshold is set, so that the vehicle energy management system 1 does not blindly completely charge the electric quantity of the battery unit 200, especially for a vehicle in a driving state, the electric quantity of the battery unit 200 is preferentially charged to the preset threshold based on the solar battery unit 300, and then the opportunity of utilizing solar energy can be further created by consuming the electric quantity of the battery unit 200. Further, for the automobile adopting the automobile energy management system 1 according to the embodiment of the present invention, when the driving state is switched to the parking state, since the highest electric quantity of the storage battery unit 200 is only at the electric quantity level of the preset threshold value, after the automobile enters the parking state, the solar battery unit 300 may be further controlled to charge the storage battery unit 200, so as to fully charge the electric quantity of the storage battery unit 200, thereby effectively solving the technical problem that the existing automobile cannot utilize solar energy resources after parking because the electric quantity of the storage battery is fully charged by the generator in the driving stage.
Preferably, the preset threshold may be preset by a user. According to the technical scheme of the embodiment of the invention, by adjusting the preset threshold value, the load power utilization output of the storage battery unit 200 in the driving process of the automobile can be effectively controlled, and more energy storage space is provided for the solar battery unit 300 which continuously collects solar energy in the parking stage of the automobile, so that the utilization efficiency of the automobile on the solar energy is better improved.
Further, the car energy management system 1 can further include a whole car control unit 400, the whole car control unit 400 is connected with the generator unit 100 and the storage battery unit 200, and when the car is in a driving state, the whole car control unit 400 controls the generator unit 100 to charge or stop charging the storage battery unit 200.
Those skilled in the art understand that according to the technical solution of the embodiment of the present invention, at least one of the generator unit 100 and the solar cell unit 300 is controlled to be connected to the battery unit 200 (the solar cell unit 300 is preferentially controlled to charge the battery unit 200) to ensure that the charge of the battery unit 200 can be maintained at a normal level.
Further, according to the technical scheme of the embodiment of the present invention, by controlling the connection between the vehicle control unit 400 and the generator unit 100 and the battery unit 200, and by controlling the connection between the photovoltaic control unit 500 and the battery unit 200 and the solar cell unit 300, the dynamic distribution of the power output of the battery unit 200, the solar cell unit 300 and the generator unit 100 is realized according to the electric quantity state of the battery unit 200, the driving state of the vehicle, the sunshine state, and other factors. In particular, the application scenarios include, but are not limited to, the following examples.
In a first preferred application scenario of this embodiment, when the vehicle is in a driving state and the electric quantity of the battery unit 200 is higher than the preset threshold, the vehicle control unit 400 controls the generator unit 100 to stop charging the battery unit and controls the generator unit 100 to drive the vehicle load 600 of the vehicle, and the photovoltaic control unit 500 controls the solar battery unit 300 to stop charging the battery unit 200 and controls the solar battery unit 300 to drive the vehicle load 600.
As a variation, the vehicle control unit 400 may further control the battery unit 200 to drive the vehicle load 600. In this variation, the vehicle control unit 400 may control the generator unit 100 to drive or stop driving the vehicle load 600.
Those skilled in the art understand that in the present application scenario, when the power of the battery unit 200 is higher than the preset threshold, the connection between the solar cell 300 and the generator unit 100 and the battery unit 200 may be disconnected, and the vehicle is driven by the solar cell 300, the generator unit 100 and the battery unit 200 together, so that the solar cell 300 can be controlled to charge the battery unit 200 again after the power of the battery unit 200 is consumed, thereby creating more opportunities for utilizing solar energy.
In a second preferred application scenario of this embodiment, when the vehicle is in a braking state, the vehicle control unit 400 controls the generator unit 100 to drive the vehicle load 600 of the vehicle, and controls the generator unit 100 to charge the battery unit 200, and the photovoltaic control unit 500 controls the solar cell unit 300 to stop charging the battery unit 200, and controls the solar cell unit 300 to drive the vehicle load.
Further, the braking state may be determined based on a brake pedal signal of the vehicle. For example, when the brake pedal signal of the vehicle is greater than a preset signal threshold, it may be determined that the vehicle is in a braking state.
Those skilled in the art understand that when the vehicle is in a deceleration braking state (i.e., the braking state), the engine unit 100 may recover energy from a brake pedal of the vehicle, and thus the recovered energy may be intensively supplemented to the battery unit 200.
In a third preferred application scenario of the present embodiment, when the vehicle is in a driving state, the electric quantity of the battery unit 200 is lower than a preset threshold, and the power of the solar battery unit 300 is greater than a preset first threshold, the photovoltaic control unit 500 controls the solar battery unit 300 to charge the battery unit 200, and controls the solar battery unit 300 to drive the vehicle load 600 of the vehicle, and the vehicle control unit 400 controls the generator unit 100 to charge or stop charging the battery unit 200.
Preferably, the vehicle control unit 400 controls the generator unit 100 to stop charging the battery unit 200, so as to better improve the utilization rate of solar energy. As a variation, an application scenario in which the generator unit 100 and the solar cell 300 charge the battery unit 200 together is not excluded in practical applications, so as to accelerate the charging speed of the battery unit 200. As another variation, when the power consumption required by the entire vehicle load 600 is small, the entire vehicle control unit 400 may further control the battery unit 200 to drive the entire vehicle load 600.
Further, the preset first threshold may be set by a user, and is used to indicate the solar radiation intensity collected by the solar battery unit 300. For example, when the power of the solar battery unit 300 is greater than the preset first threshold, the current sunshine intensity in the environment outside the automobile may be considered to be higher, and the photoelectric conversion efficiency of the solar battery unit 300 is also higher; for another example, when the power of the solar battery cell 300 is smaller than the first threshold value, the current sunshine intensity in the environment outside the automobile may be considered to be low, and the photoelectric conversion efficiency of the solar battery cell 300 may also be considered to be low.
Those skilled in the art will appreciate that, in the present application scenario, the sunlight of the external environment is sufficient, so that the solar cell unit 300 can charge the battery unit 200 while still driving the entire vehicle load 600. As a non-limiting variation, when the electric quantity of the battery unit 200 reaches the preset threshold, the application scenario may further be changed to the aforementioned application scenario, that is, the generator unit 100, the battery unit 200, and the solar battery unit 300 drive the entire vehicle load 600 together.
In a fourth preferred application scenario of this embodiment, when the vehicle is in a driving state, the electric quantity of the battery unit 200 is lower than a preset threshold, and the power of the solar battery unit 300 is smaller than a preset second threshold, the vehicle control unit 400 controls the generator unit 100 to stop charging the battery unit 200, and controls the generator unit 100 to drive the vehicle load 600 of the vehicle, and the photovoltaic control unit 500 controls the solar battery unit 300 to charge the battery unit 200, and controls the solar battery unit 300 to stop driving the vehicle load 600.
Further, similar to the preset first threshold, the preset second threshold may also be set by the user, and is also used to indicate the solar radiation intensity collected by the solar battery unit 300. Preferably, the preset second threshold is smaller than or equal to the preset first threshold.
Those skilled in the art will understand that, in the present application scenario, since the sunlight of the external environment is weak, so that the solar cell 300 can charge the battery unit 200 without any residual power to drive the entire vehicle load 600, in the present application scenario, the solar cell 300 is only used for charging the battery unit 200, and the entire vehicle load 600 is only driven by the generator unit 100.
As a non-limiting variation, in order to better increase the charging speed of the battery unit 200, in the application scenario, the generator unit 100 may be further controlled to drive the entire vehicle load 600 and simultaneously charge the battery unit 200 together with the solar battery unit 300.
In a fifth preferred application scenario of the present embodiment, when the automobile is in a driving state and the electric quantity of the battery unit 200 is lower than the preset threshold but higher than a preset critical threshold, the entire automobile control unit 400 controls the generator unit 100 to stop charging the battery unit 200, and the photovoltaic control unit 500 controls the solar battery unit 300 to charge the battery unit 200, wherein the preset critical threshold is smaller than the preset threshold.
Further, the preset critical threshold may be set by a user, for example, may be a critical power level for feeding a battery included in the battery unit 200.
Those skilled in the art understand that in the present application scenario, the charge of the battery unit 200 is at a normal level, and the battery unit 200 can be charged only by the solar cell 300, so as to better utilize the solar energy resource.
Further, when the entire vehicle load 600 of the vehicle needs to use electricity, the entire vehicle control unit 400 may control the generator unit 100 to drive the entire vehicle load 600.
Further, when the external sunshine is sufficient (for example, the power of the solar cell 300 is greater than the preset first threshold), the photovoltaic control unit 500 may control the solar cell 300 to drive the entire vehicle load 600.
In a sixth preferred application scenario of the present embodiment, when the automobile is in a driving state and the electric quantity of the battery unit 200 is lower than a preset critical threshold, the vehicle control unit 400 controls the generator unit 100 to charge the battery unit 200, and the photovoltaic control unit 500 controls the solar battery unit 300 to charge the battery unit 200, where the preset critical threshold is smaller than the preset threshold.
Further, the preset critical threshold may be a critical power level for feeding a battery included in the battery unit 200; the power level higher than the critical power level and lower than the preset threshold may be preset by the user to better protect the battery unit 200 and avoid the battery feeding situation.
Those skilled in the art understand that in the application scenario, since the electric quantity of the battery unit 200 is low and the possibility of power feeding is close to occurring, the photovoltaic control unit 500 controls the solar battery unit 300 to charge only the battery unit 200, and the vehicle control unit 400 also controls the generator unit 100 to charge the battery unit 200 together, so as to effectively increase the charging speed of the battery unit 200, so as to increase the electric quantity of the battery unit 200 faster and effectively avoid the occurrence of the battery power feeding condition.
Further, whole car the control unit 400 can also control generator unit 100 drive whole car load 600 of car is in order to guarantee when whole car load 600 of car obtains sufficient electric power support, give as early as possible battery pack 200 charges, until battery pack 200's electric quantity reaches after predetermineeing critical threshold value, whole car the control unit 400 can control generator unit 100 stop to battery pack 200 charges, make only by solar cell unit 300 to battery pack 200 charges, improves the utilization ratio to solar energy resource.
In a seventh preferred application scenario of the present embodiment, when the automobile is in a parking state and the electric quantity of the storage battery unit 200 is lower than the preset threshold, the photovoltaic control unit 500 controls the solar battery unit 300 to charge the storage battery unit 200, and the vehicle control unit 400 controls the generator unit 100 to stop charging the storage battery unit 200.
As will be understood by those skilled in the art, in this application scenario, when the vehicle initially enters the parking state, the electric quantity of the battery unit 200 reaches the preset threshold at most, in order to prevent the battery feeding phenomenon caused by the vehicle being idle for a long time, the electric quantity of the battery unit 200 needs to be maintained at the highest electric quantity level, and since the generator unit 100 of the vehicle stops working, the battery unit 200 is charged only by the solar cell 300 until the electric quantity of the battery unit 200 is fully charged, and when the electric quantity of the battery unit 200 subsequently falls below the preset threshold, the battery unit 200 is charged again based on the solar cell 300, so as to more effectively avoid the battery feeding.
In an eighth preferred application scenario of the present embodiment, when the vehicle is in a parking state, the electric quantity of the battery unit 200 is higher than the preset threshold and meets a preset condition, the photovoltaic control unit 500 controls the solar battery unit 300 to stop charging the battery unit 200, and controls the solar battery unit 300 to drive the photovoltaic extension load 700 of the vehicle, and the vehicle control unit 400 controls the generator unit 100 to stop charging the battery unit 200.
Further, the photovoltaic extension load 700 may be used to provide comfort services to users. For example, the photovoltaic extension load 700 may include a smart fan, seat semiconductor cooling, rear view mirror heating, and the like.
Further, the preset condition may be preset by a user, so that when the vehicle is parked and not powered on, the photovoltaic control unit 500 automatically determines whether the photovoltaic extension load 700 needs to be driven according to the preset condition, thereby creating a better comfort experience for the user. For example, a user may preset a car using time, and the photovoltaic control unit 500 may drive the intelligent ventilation system of the car based on the solar cell unit 300 to update air in the car according to the car using time by ten minutes; for another example, according to the preset of the user, the photovoltaic control unit 500 may further control the solar cell unit 300 to drive the seat to heat when the temperature in the vehicle of the automobile is lower than 10 ℃.
