[0042] Exemplary photovoltaic charging system

[0043] Please see Figure 1 In one exemplary embodiment, a photovoltaic charging system is provided. For example... Figure 1 As shown, the photovoltaic charging system includes a photovoltaic module 100 and a charging control module 200;

[0044] The charging control module 200 is connected between the photovoltaic module 100 and the vehicle's charging port 300;

[0045] The charging control module 200 is turned on when it is determined through the vehicle's charging port 300 that the charging gun is inserted into the vehicle's charging port 300, so that the photovoltaic module 100 charges the vehicle's power battery through the vehicle's charging port 300.

[0046] The vehicle's charging port is located on the vehicle's surface. The charging control module is connected between the photovoltaic module and the vehicle's charging port. The charging control module is activated when it determines that the charging gun is inserted into the vehicle's charging port, allowing the photovoltaic module to charge the vehicle's power battery through the charging port. The entire photovoltaic charging system can be installed on the outside of the vehicle. The photovoltaic charging system only needs to be connected to the charging port located on the vehicle's surface, without modifying the vehicle's internal circuitry. This simplifies implementation and utilizes a stable and independent photovoltaic charging system. Since no modification to the vehicle's internal circuitry is required, the stability of the photovoltaic charging system is improved, and the failure rate of the photovoltaic charging system is reduced. Furthermore, the charging control module can be activated manually by inserting the charging gun into the vehicle's charging port, thereby enabling the photovoltaic module to charge the vehicle's power battery through the charging port. This allows for manual control of whether charging is initiated, making charging control very convenient.

[0047] In an exemplary embodiment, the vehicle's charging port 300 can be a slow charging port. The vehicle's charging port 300 is connected to an on-board charger, which is connected to the vehicle's power battery, thereby enabling the vehicle's power battery to be charged through the vehicle's charging port 300.

[0048] According to the high-voltage power distribution status, the operating conditions of electric vehicles can be divided into three levels: OFF, ON, and READY. The current feasible photovoltaic charging schemes are as follows: (1) Photovoltaic module directly connected to the power battery: It can charge in all three operating conditions, but the safety of this scheme is poor, especially in the OFF position, the battery will be depleted, and the reliability is low. Unless the original vehicle scheme is modified, the battery is very likely to be depleted. (2) Photovoltaic directly connected to the high-voltage auxiliary drive controller: It can charge only in the ON and READY positions, but this scheme cannot charge when the vehicle is parked in the OFF position, and the system is complicated; the photovoltaic module does not work when the vehicle is turned off. (3) Photovoltaic connected to the low-voltage system: The solar power generation is not enough to be fully utilized, and the overall vehicle efficiency is very low. All three schemes require changes to the original vehicle's electrical system hardware and software.

[0049] The photovoltaic charging system in this application uses clean and renewable energy, is environmentally friendly and energy-saving, and is a clean, efficient, and intelligent new energy vehicle charging solution. The photovoltaic charging system in this application is highly integrated, resulting in high overall vehicle efficiency. By connecting the charging port to a high-voltage system, it avoids the drawback of insufficient solar power generation in low-voltage systems, effectively improving overall vehicle efficiency. The photovoltaic charging system in this application requires the original vehicle to have a slow-charging configuration. It can charge in both OFF and ON positions. The system is simple and reliable, does not operate while the vehicle is in motion, and is flexible, allowing for charging at any time after parking. It is easy to implement, meets various applications, and can be used on multiple vehicle models. It uses a slow-charging gun and on-board charger control, employs a slow-charging plug-in method for initiation, and uses manual plug-in control. It adopts the national standard slow-charging method, making it very convenient for vehicle application. It can also slow-charge other vehicles with slow-charging capabilities, making its application scenarios wide-ranging.

[0050] The photovoltaic charging system in this application develops a relatively simple photovoltaic high-voltage connection system solution without modifying the internal circuit of the vehicle. The external circuit does not need to change the internal circuit of the vehicle. It adopts a stable and independent photovoltaic charging system. Since it does not require modification of the vehicle's internal circuit, the stability of the photovoltaic charging system is improved and the failure rate of the photovoltaic charging system is reduced.

[0051] In some embodiments, such as Figure 2 As shown, the charging control module 200 includes a photovoltaic inverter 210 and a control and guidance circuit 220;

[0052] The photovoltaic inverter 210 is used to convert the direct current output from the photovoltaic module 100 into alternating current.

[0053] The control and guidance circuit 220 is connected between the photovoltaic inverter 210 and the vehicle's charging port 300;

[0054] The control and guidance circuit 220 is turned on when it is determined through the vehicle's charging port 300 that the charging gun is inserted into the vehicle's charging port 300, so that alternating current can be used to charge the vehicle's power battery through the vehicle's charging port 300.

[0055] The photovoltaic inverter 210 converts the DC power output from the photovoltaic module 100 into AC power. The control circuit 220 is turned on when the charging gun is inserted into the vehicle's charging port 300, so that the AC power can charge the vehicle's power battery through the vehicle's charging port 300. The control circuit 220 can be turned on by manually inserting the charging gun into the vehicle's charging port, thereby realizing the AC power charging the vehicle's power battery through the vehicle's charging port. The charging is very convenient and can be manually controlled.

[0056] In an exemplary embodiment, the photovoltaic inverter 210 may be installed on the top of the cargo box of the vehicle.

[0059] In addition, it receives the control guidance signal output by the photovoltaic inverter 210, wherein the control guidance signal carries the duty cycle of the AC power.

[0060] In addition, in response to the charging connection confirmation signal and the control guidance signal, the AC power is turned on to charge the vehicle's power battery through the vehicle's charging port 300.

[0064] The control guidance circuit 220 receives a charging connection confirmation signal output from the vehicle's charging port 300 and a control guidance signal output from the photovoltaic inverter 210. It then responds to both the charging connection confirmation signal and the control guidance signal by conducting to allow AC power to flow through the vehicle's charging port 300 to charge the vehicle's power battery. Specifically, the control guidance circuit 220 conducts when the charging gun is inserted into the vehicle's charging port 300 and the AC power's duty cycle is greater than a preset duty cycle, thus allowing AC power to flow through the vehicle's charging port 300 to charge the vehicle's power battery. The control guidance circuit 220 can be activated manually by inserting the charging gun into the vehicle's charging port, enabling manual control of charging and providing convenient charging control.

[0065] In some embodiments, such as Figure 3 As shown, the control and guidance circuit 220 includes a controllable switch 221 and a control circuit 222;

[0066] A controllable switch 221 is connected between the photovoltaic inverter 210 and the vehicle's charging port 300;

[0067] Control circuit 222 is used for:

[0068] Receives the charging connection confirmation signal output from the vehicle's charging port 300;

[0070] In addition, in response to the charging connection confirmation signal and the control guidance signal, the controllable switch 221 is closed so that AC power can be used to charge the vehicle's power battery through the vehicle's charging port 300.

[0071] In an exemplary embodiment, the control circuit 222 controls the controllable switch 221 to close in response to a charging connection confirmation signal and a control guidance signal. Specifically, when the charging connection confirmation signal indicates that the charging gun has been inserted into the vehicle's charging port 300, and the control guidance signal indicates that the duty cycle of the AC power is greater than a preset duty cycle, the control circuit 222 controls the controllable switch 221 to close.

[0072] The control circuit 222 receives a charging connection confirmation signal from the vehicle's charging port 300 and a control guidance signal from the photovoltaic inverter 210. In response to the charging connection confirmation signal and the control guidance signal, it controls the controllable switch 221 to close, allowing AC power to flow through the vehicle's charging port 300 to charge the vehicle's power battery. Specifically, when the charging gun is inserted into the vehicle's charging port 300 and the AC power's duty cycle is greater than a preset duty cycle, the control circuit 222 controls the controllable switch 221 to close, thus allowing AC power to flow through the vehicle's charging port 300 to charge the vehicle's power battery. The control circuit 222 can also manually close the controllable switch 221 by manually inserting the charging gun into the vehicle's charging port, enabling manual control of charging and providing convenient charging control.

[0074] The photovoltaic inverter 210 is used to convert the direct current output from the photovoltaic module 100 into alternating current.

[0075] The control and guidance circuit 220 is connected between the photovoltaic inverter 210 and the wiring harness 230;

[0076] The control and guidance circuit 220 is turned on when it is determined by the vehicle's charging port 300 that the charging gun is inserted into the vehicle's charging port 300, so that AC power is used to charge the vehicle's power battery through the vehicle's charging port 300.

[0077] The wiring harness 230 is connected between the control and guidance circuit 220 and the vehicle's charging port 300;

[0078] The wiring harness 230 is detachably connected to the vehicle's charging port 300.

[0079] The wiring harness 230 is connected between the control and guidance circuit 220 and the vehicle's charging port 300. The wiring harness 230 and the vehicle's charging port 300 are detachably connected. When the power battery of other vehicles needs to be connected to the photovoltaic module 100 for charging, the wiring harness 230 can be connected to the charging port of other vehicles to enable charging of external vehicles, making the application flexible.

[0091] A preset distance is maintained between the photovoltaic module 100 and the cargo box of the vehicle, allowing air to flow between them. This facilitates heat dissipation for the photovoltaic module 100 and also makes it easier to remove dust from the surface of both the photovoltaic module 100 and the cargo box of the vehicle.
