Electric vehicles are touted by the masses because of the energy conservation and environmental protection. Electric vehicles typically use an external power source to charge a battery module of the vehicle, which may be used to provide electrical energy for the travel of the vehicle and the operation of various electrical components of the vehicle. However, when the battery module of the vehicle has an excessively low electric power and no external power source is provided in the periphery, there are problems in that the vehicle cannot travel and the vehicle electrical components cannot operate. To solve this problem, the present application provides a photovoltaic charging system 100 and a vehicle 1000 (shown in fig. 1).

Referring to fig. 1, a photovoltaic charging system 100 according to an embodiment of the present application includes a photovoltaic charging assembly 10 and a charging cover assembly 50. The photovoltaic charging assembly 10 is used to convert light energy into electrical energy. The charging cover assembly 50 includes a charging cover 51, and an electrical connection between the photovoltaic charging assembly 10 and the battery module 300 of the load is made in a closed state of the charging cover 51; with the charging cover 51 in an open state, the electrical connection between the photovoltaic charging assembly 10 and the loaded battery module 300 is disconnected.

Specifically, the photovoltaic charging system 100 is a structure for converting light energy into electric energy to charge a load electrically connected to the photovoltaic charging system 100, and the load that can be charged using the photovoltaic charging system 100 may be, but is not limited to, a vehicle, a street lamp, a water heater, a solar fan, and the like. The load of the embodiment of the application is a vehicle 1000, and the photovoltaic charging system 100 is used for charging the vehicle 1000.

The photovoltaic charging assembly 10 is a structure for converting light energy into electric energy to charge other elements, and the photovoltaic charging assembly 10 of the present application is used for charging the battery module 300 of the vehicle 1000.

The charging cover 51 of the charging cover assembly 50 is used in an opened state to electrically connect an external power source to the vehicle 1000 to charge the vehicle 1000. The charging cover 51 of the charging cover assembly 50 is used to conduct the photovoltaic charging system 100 and the battery module 300 in a closed state, so that the photovoltaic charging system 100 charges the vehicle 1000.

In the case where no external power source charges the battery module 300 of the vehicle 1000, the charging cover 51 is in a closed state for avoiding a problem in that oil smoke or dust, etc. fall into the remaining elements of the charging cover assembly 50, thereby causing the elements to be damaged. Meanwhile, the charging cover 51 can also play a role in decoration, so that the overall aesthetic degree of the vehicle 1000 is better. Preferably, the material of the charging cover 51 is the same as that of the outer casing of the vehicle 1000, so that the uniformity and the aesthetic appearance of the vehicle 1000 are better. The cross-sectional shape of the charging cover 51 may be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shape, etc.

In the photovoltaic charging system 100 according to the embodiment of the present application, the photovoltaic charging module 10 is used to charge the battery module 300 of the load when the charging cover 51 is in the closed state. In the state where the charging cover 51 is opened, the photovoltaic charging module 10 stops charging the battery module 300 of the load. In the photovoltaic charging system 100 of the present application, when the vehicle 1000 is not charged by using an external power source, the photovoltaic charging system 100 is used for charging the vehicle 1000, so as to ensure that the battery module 300 of the vehicle 1000 has sufficient electric power at any time, and avoid the problems that the vehicle 1000 cannot run and the electrical components of the vehicle 1000 cannot work due to the too low electric power of the battery module 300 of the vehicle 1000.

The photovoltaic charging system 100 is further described below with reference to the accompanying figures.

Referring to fig. 1, in some embodiments, the photovoltaic charging system 100 further includes a switch unit 30, where the switch unit 30 electrically connects the photovoltaic charging assembly 10 and the battery module 300 of the load, and when the charging cover 51 is in the closed state, the switch unit 30 turns on the electrical connection between the photovoltaic charging assembly 10 and the battery module 300 of the load; the switching unit 30 disconnects the electrical connection between the photovoltaic charging module 10 and the battery module 300 of the load when the charging cover 51 is in an open state.

In the case where the photovoltaic charging module 10 is required to charge the battery module 300 of the vehicle 1000, the switching unit 30 is used to conduct the electrical connection between the photovoltaic charging module 10 and the battery module 300, so that the photovoltaic charging module 10 can charge the battery module 300. In the case where the photovoltaic charging module 10 is not required to charge the battery module 300 of the vehicle 1000, the switching unit 30 serves to disconnect the electrical connection between the photovoltaic charging module 10 and the battery module 300, so that the photovoltaic charging module 10 stops charging the battery module 300.

In some embodiments, the switch unit 30 is a charging cover 51, and the charging cover 51 electrically connects the photovoltaic charging assembly 10 and the battery module 300 of the load. When the charging cover 51 is in the closed state, the charging cover 51 conducts the electrical connection between the photovoltaic charging assembly 10 and the battery module 300 of the load. When the charging cover 51 is in the open state, the charging cover 51 breaks the electrical connection between the photovoltaic charging assembly 10 and the battery module 300 of the load. For example, a relay structure is provided on the charging cover 51, and when the charging cover 51 is in a closed state, that is, when the charging cover 51 is in a closed state, the circuit is conducted between the photovoltaic charging module 10 and the battery module 300 of the load, and the current flows through the relay, so that the relay conducts the electrical connection between the photovoltaic charging module 10 and the battery module 300 of the load. When the charging cover 51 is in the open state, that is, when the charging cover 51 is in the open state, the electrical circuit is disconnected from both the photovoltaic charging module 10 and the battery module 300 of the load, the current in the relay disappears, and the relay disconnects the electrical connection between the photovoltaic charging module 10 and the battery module 300 of the load.

Referring to fig. 1 and 2, in other embodiments, the charging cover assembly 50 further includes a sensor 53, the sensor 53 is electrically connected to the switch unit 30, and when the charging cover 51 is in the closed state, the sensor 53 is configured to output a first signal, and the first signal is configured to enable the switch unit 30 to conduct the electrical connection between the photovoltaic charging assembly 10 and the battery module 300 of the load; when the charging cover 51 is in the open state, the sensor 53 is configured to output a second signal for disconnecting the electrical connection between the photovoltaic charging module 10 and the battery module 300 of the load by the switching unit 30.

Specifically, the sensor 53 is a structure for detecting the open state and the closed state of the charging cover 51. The sensor 53 is also used to output a first signal and a second signal. The sensor 53 of the present application includes at least one of a pressure sensor, an image sensor, an infrared sensor, and an ultrasonic sensor.

In one embodiment, sensor 53 is a pressure sensor. In the case where the pressure of the charging cover 51 acts on the pressure sensor, the sensor 53 detects that the charging cover 51 is in the closed state, and the sensor 53 outputs a first signal. In the case where the pressure sensor does not detect the pressure from the charging cover 51, the sensor 53 detects that the charging cover 51 is in the open state, and the sensor 53 outputs the second signal. In another embodiment, the sensor 53 is an image sensor. The image sensor calculates the distance between the image sensor and the charging cover 51 by photographing the charging cover 51. When the charging cover 51 is in the closed state, the distance L between the image sensor and the charging cover 51 is minimum. In the case where the distance between the image sensor and the charging cover 51 is L, the sensor 53 detects that the charging cover 51 at this time is in the closed state. In the case where the distance between the image sensor and the charging cover 51 is greater than L, the sensor 53 detects that the charging cover 51 at this time is in an open state. In yet another embodiment, the sensor 53 is an infrared sensor. The distance from the infrared sensor to the charging cover 51 is calculated from the time from the infrared light emitted by the infrared sensor to the time when the infrared light hits the charging cover 51 and is reflected back to the infrared sensor. In the case where the charging cover 51 is in the closed state, the distance L between the infrared sensor and the charging cover 51 is minimum. In the case where the distance between the infrared sensor and the charging cover 51 is L, the sensor 53 detects that the charging cover 51 at this time is in the closed state. In the case where the distance between the infrared sensor and the charging cover 51 is greater than L, the sensor 53 detects that the charging cover 51 at this time is in an open state. In yet another embodiment, the sensor 53 is an ultrasonic sensor. The distance from the ultrasonic sensor to the charging cover 51 is calculated from the time from the ultrasonic wave emitted by the ultrasonic sensor to the time when the ultrasonic wave hits the charging cover 51 and is reflected back to the ultrasonic sensor. When the charging cover 51 is in the closed state, the distance L between the ultrasonic sensor and the charging cover 51 is minimum. In the case where the distance between the ultrasonic sensor and the charging cover 51 is L, the sensor 53 detects that the charging cover 51 at this time is in the closed state. In the case where the distance between the ultrasonic sensor and the charging cover 51 is greater than L, the sensor 53 detects that the charging cover 51 at this time is in an open state.

In the state in which the charging cover 51 is opened, the external power source charges the battery module 300 of the vehicle 1000. At this time, the sensor 53 detects that the charging cover 51 is in an open state, the sensor 53 transmits a second signal to the switching unit 30, and the switching unit 30 disconnects the electrical connection between the photovoltaic charging module 10 and the battery module 300 after the switching unit 30 receives the second signal, so that the photovoltaic charging module 10 stops charging the battery module 300. In the closed state of the charging cover 51, no external power source charges the battery module 300 of the vehicle 1000 at this time. The sensor 53 detects that the charging cover 51 is in the closed state, the sensor 53 transmits a first signal to the switch unit 30, and after the switch unit 30 receives the first signal, the switch unit 30 conducts the electrical connection between the photovoltaic charging module 10 and the battery module 300, so that the photovoltaic charging module 10 charges the battery module 300.

Referring to fig. 1, 3 and 4, in some embodiments, the switch unit 30 includes a circuit breaker 31 and a signal collector 33. The circuit breaker 31 is electrically connected to the photovoltaic charging module 10 and the battery module 300, respectively. The signal collector 33 is electrically connected with the circuit breaker 31, the signal collector 33 is in communication connection with the charging cover assembly 50, and the circuit breaker 31 conducts the electrical connection between the photovoltaic charging assembly 10 and the battery module 300 under the condition that the signal collector 33 receives the first signal transmitted by the charging cover assembly 50; the signal collector 33, upon receiving the second signal transmitted from the charging cover assembly 50, the circuit breaker 31 breaks the electrical connection between the photovoltaic charging assembly 10 and the battery module 300.

Specifically, the circuit breaker 31 is a structure for making or breaking a circuit. The circuit breaker 31 is typically comprised of a contact system, an arc extinguishing system, an operating mechanism, a trip, a housing, etc. In the case where the circuit breaker 31 conducts the circuit between the photovoltaic charging module 10 and the battery module 300, the photovoltaic charging module 10 charges the battery module 300. In the case where the circuit breaker 31 breaks the circuit between the photovoltaic charging module 10 and the battery module 300, the photovoltaic charging module 10 stops charging the battery module 300.

The signal collector 33 is used to collect the first signal and the second signal output from the charging cover assembly 50. In one embodiment, the signal collector 33 directly controls the circuit breaker 31 to make or break the electrical connection between the photovoltaic charging assembly 10 and the battery module 300. In the case where the signal collector 33 collects the first signal, the signal collector 33 controls the circuit breaker 31 to conduct the electrical connection between the photovoltaic charging module 10 and the battery module 300. In the case where the signal collector 33 collects the second signal, the signal collector 33 controls the circuit breaker 31 to disconnect the electrical connection between the photovoltaic charging module 10 and the battery module 300. In another embodiment, the switching unit 30 may further include a processor. In the case where the signal collector 33 collects the first signal, the signal collector 33 transmits the first signal to the processor, and the processor controls the circuit breaker 31 to conduct the electrical connection between the photovoltaic charging module 10 and the battery module 300. In the case where the signal collector 33 collects the second signal, the signal collector 33 transmits the second signal to the processor, and the processor controls the circuit breaker 31 to disconnect the electrical connection between the photovoltaic charging module 10 and the battery module 300.

The charging cover assembly 50 transmits a signal to the switching unit 30, and the signal collector 33 receives the first signal or the second signal to control the circuit breaker 31 to turn on or off a circuit, thereby realizing that the photovoltaic charging assembly 10 automatically charges the battery module 300 of the load or automatically stops charging the battery module 300 of the load.

With continued reference to fig. 1, 3 and 4, in some embodiments, the switch unit 30 further includes a charging circuit 35, the circuit breaker 31 is disposed on the charging circuit 35, an input end 351 of the charging circuit 35 is electrically connected to the photovoltaic panel 11 through the electrical connector 13 of the photovoltaic charging assembly 10, and an output end 353 of the charging circuit 35 is electrically connected to the battery module 300 of the load.

The charging circuit 35 is used for electrically connecting the photovoltaic charging module 10 and the battery module 300 to conduct the photovoltaic charging module 10 and the battery module 300, so that the photovoltaic charging module 10 can charge the battery module 300. The circuit breaker 31 is provided on the charging circuit 35, so that not only can the conduction between the photovoltaic charging module 10 and the battery module 300 be realized, but also the disconnection of the electrical connection between the photovoltaic charging module 10 and the battery module 300 can be controlled. In the case where the photovoltaic charging module 10 needs to charge the battery module 300, the circuit breaker 31 turns on the charging circuit 35, so that the photovoltaic charging module 10 and the battery module 300 are turned on through the charging circuit 35. In the case where the photovoltaic charging module 10 is not required to charge the battery module 300, the circuit breaker 31 opens the charging circuit 35, thereby disconnecting the electrical connection between the photovoltaic charging module 10 and the battery module 300.

The input end 351 of the charging circuit 35 is electrically connected to the dc booster 15 via the electrical connection 13, and is further electrically connected to the photovoltaic panel 11. The output 353 of the charging circuit 35 is electrically connected to the battery module 300 through a wire. The electric energy generated by the photovoltaic charging module 10 enters the charging circuit 35 from the input end 351 of the charging circuit 35, and when the circuit breaker 31 conducts the charging circuit 35, the electric energy entering the charging circuit 35 is output to the battery module 300 from the output end 353 of the charging circuit 35 through a wire, so that the photovoltaic charging module 10 charges the battery module 300.

Referring to fig. 2 and 4, in one embodiment, the sensor 53 is electrically connected to the signal collector 33 of the switch unit 30, and the sensor 53 is configured to output the first signal and the second signal to the signal collector 33.

In another example, a radio connection is used between the sensor 53 and the signal collector 33. The radio connection propagates in space through electromagnetic wave signals to enable information transfer between the sensor 53 and the signal collector 33. Radio connection means include, but are not limited to, bluetooth, wireless broadband, near Field Communication (NFC), and infrared Communication.

Referring to fig. 2 and 4, in another embodiment, the charging cover assembly 50 further includes a signal transmission member 55, where the signal transmission member 55 is electrically connected to the sensor 53, and the signal transmission member 55 is configured to transmit the first signal and the second signal sent by the sensor 53 to the signal collector 33 of the switch unit 30. Wherein, in case the sensor 53 detects that the charging cover 51 is in the closed state, the sensor 53 sends a first signal to the signal transmission member 55, and the signal transmission member 55 outputs the first signal to the signal collector 33. In the case where the sensor 53 detects that the charging cover 51 is in the open state, the sensor 53 sends out a second signal to the signal transmission member 55, and the signal transmission member 55 outputs the second signal to the signal collector 33.

In one example, a wired electrical connection is used between signal transmission member 55 and signal collector 33. The wired electrical connection may connect signal transmission member 55 and signal collector 33 by means of metal wires or optical fibers or the like to enable information to be transferred between signal transmission member 55 and signal collector 33.

One end of the direct current booster 15 is connected with the photovoltaic panel 11, the other end of the direct current booster 15 is connected with the electric connector 13, and the direct current booster 15 is used for boosting electric energy generated by the photovoltaic panel 11 to a voltage level allowed by the battery module 300 of the load and transmitting the electric energy to the battery module 300 of the load through the electric connector 13.

Specifically, the photovoltaic panel 11 is a structure capable of generating a photovoltaic effect under light conditions to convert light energy into electric energy to charge other elements. The photovoltaic panel 11 is made of a semiconductor material, and a currently more common material is silicon, wherein the silicon may be monocrystalline silicon or polycrystalline silicon. The photovoltaic panel 11 may be mounted on the surface of the vehicle 1000, preferably, the photovoltaic panel 11 is mounted on the top of the vehicle 1000, at this time, the photovoltaic panel 11 is mounted on the vehicle 1000 more firmly, and the area of the photovoltaic panel 11 capable of receiving sunlight is larger. The larger the area of the photovoltaic panel 11, the more sunlight the photovoltaic panel 11 is able to absorb, and thus the greater the energy of the converted electrical energy. Therefore, in the case where the area of the photovoltaic panel 11 is large, the speed at which the photovoltaic charging assembly 10 charges the battery module 300 is high. However, the area of the photovoltaic panel 11 should not be excessively large, and in the case where the area of the photovoltaic panel 11 exceeds the area of the top of the vehicle 1000 by a large amount, the photovoltaic panel 11 may increase the entire volume of the vehicle 1000 and the photovoltaic panel 11 may be at risk of unstable installation.

In one embodiment, the photovoltaic panel 11 is a monolithic structure, and the photovoltaic panel 11 is not foldable. At this time, the photovoltaic panel 11 is conveniently processed. In another embodiment, the photovoltaic panel 11 is a collapsible structure. At this time, the photovoltaic panel 11 is easy to store. The photovoltaic panel 11 can be folded and stored without requiring a large space when not in use.

The voltage at the output of the dc booster 15 is higher than the voltage at the input. The dc booster 15 boosts the dc signal of the photovoltaic panel 11 through components such as an inductor and a diode, and finally outputs a voltage suitable for the battery module 300 to charge the battery module 300. Meanwhile, the direct current booster 15 is also used for monitoring the charging process of the battery module 300, so that the battery module 300 is prevented from being damaged due to overhigh voltage or overlarge current, and the stability and the safety of the charging process can be ensured.

The electric energy generated by the photovoltaic panel 11 is boosted to a voltage suitable for the battery module 300 by the dc booster 15, and the electric energy is output from the dc booster 15 to the electric connector 13. The electrical connector 13 is used for electrically connecting with the switch unit 30, and the electrical connector 13 transmits the electrical energy output from the dc booster 15 to the charging circuit 35 of the switch unit 30. The charging circuit 35 of the switching unit 30 is electrically connected with the battery module 300, so that electric energy is output to the battery module 300, and the charging of the battery module 300 by the photovoltaic charging module 10 is realized.

Among them, the battery module 300 is a structure that provides electric power for the running of the vehicle 1000 and the operation of electric components inside the vehicle 1000.

In the vehicle 1000 according to the embodiment of the application, the photovoltaic charging module 10 is used to charge the battery module 300 of the load in the state where the charging cover 51 is closed. In the state where the charging cover 51 is opened, the photovoltaic charging module 10 stops charging the battery module 300 of the load. In the photovoltaic charging system 100 of the present application, when the vehicle 1000 is not charged by using an external power source, the photovoltaic charging system 100 is used for charging the vehicle 1000, so as to ensure that the battery module 300 of the vehicle 1000 has sufficient electric power at any time, and avoid the problems that the vehicle 1000 cannot run and the electrical components of the vehicle 1000 cannot work due to the too low electric power of the battery module 300 of the vehicle 1000.
