[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] It should be noted that the on-board charging system and vehicle provided in the present application relate to the field of on-board charging technology. The above is only an example and does not limit the application field of the method and system name provided in the present application.

[0031] As mentioned above, with the continuous updating and rapid development of technology, vehicles have become an indispensable part of modern society. They are widely used in people's daily lives, and vehicles can also provide users with services such as power supply for mobile terminal devices. In the relevant technical solutions, different power supply control switches are configured for the vehicle to realize power supply for different forms of power supply devices in the vehicle.

[0032] For example, the power supply device of type A in the vehicle is equipped with a power supply control switch A, and the power supply device of type B in the vehicle is equipped with a power supply control switch B. That is, if the power supply device of type A needs to be used, the power supply control switch A needs to provide power to the power supply device of type A, and if the power supply device of type B needs to be used, the power supply control switch B needs to provide power to the power supply device of type B, which may lead to a reduction in the power supply management performance of the vehicle. Therefore, how to improve the power supply management performance of the vehicle is a key issue that those skilled in the art are concerned about.

[0033] Therefore, the inventor proposed the technical solution of the present application. The vehicle-mounted charging system in the technical solution of the present application includes a battery, a power supply control module, a relay and a vehicle-mounted power supply module. Specifically, the battery is connected to the power supply control module, and the battery is connected to the relay. The battery is used to send the electric energy in the battery to the power supply control module and the relay when the vehicle starts; the power supply control module is connected to the relay, and the power supply control module is used to generate a power supply start signal according to the electric energy, and send the power supply start signal to the relay; the relay is connected to the vehicle-mounted power supply module, and the relay is used to transmit the electric energy to the vehicle-mounted power supply module according to the power supply start signal; the vehicle-mounted power supply module is used to charge the mobile terminal device according to the electric energy.

[0034] It can be seen that the technical solution of the present application proposes that the power supply start signal generated by the power supply control module can be used to enable the relay to transmit electric energy to the vehicle power supply module, and at this time the vehicle power supply module can charge the mobile terminal device according to the obtained electric energy. In this way, the power supply control module in the technical solution of the present application can realize the power supply control of the vehicle power supply module, that is, the vehicle power supply module can obtain electric energy only after the power supply control module outputs the power supply start signal, and the vehicle power supply module can provide charging services for the mobile terminal device, thereby avoiding the risk of error in the vehicle power supply to a certain extent, and thus improving the power supply management performance of the vehicle.

[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] See also Figure 1 , Figure 1 A system schematic diagram of a vehicle charging system provided in an embodiment of the present application, such as Figure 1 As shown:

[0037] First of all, it should be noted that the vehicle charging system proposed in this application includes a battery, a power supply control module, a relay and a vehicle power supply module. Specifically, the battery is connected to the power supply control module, and the battery is also connected to the relay. The battery includes pre-stored electrical energy, which is specifically used to send electrical energy to the power supply control module and the relay when the user uses the vehicle key to start the vehicle.

[0038] Furthermore, the power supply control module is connected to the relay, and the power supply control module can generate a power supply start signal according to the electric energy transmitted by the battery, and send the power supply start signal to the relay, wherein the power supply start signal is used to indicate that the relay can perform the power transmission operation. And the relay is connected to the vehicle power supply module, and the relay is used to transmit the electric energy to the vehicle power supply module according to the power supply start signal. After receiving the electric energy transmitted by the relay, the vehicle power supply module is specifically used to charge the mobile terminal device according to the electric energy. The mobile terminal device includes a mobile phone, a laptop computer and a handheld computer. It should be noted that the mobile terminal device is not limited in this application.

[0039] In one feasible implementation, the relay is a 20A (ampere) electromagnetic relay. Specifically, it should be noted that in the present application, after receiving the electric energy transmitted by the battery, the power supply control module can also determine whether the electric energy is in a high-level state. If the electric energy is in a non-high-level state (i.e., a low-level state), the power supply control module is specifically used to generate a power supply start signal based on the electric energy in a non-high-level state, and send the power supply start signal to the relay, wherein the relay is in an energized state. It can be understood that when the relay receives the power supply start signal transmitted by the power supply control module, the state of the relay is in an energized state, so that the electric energy in the battery can be sent to the vehicle-mounted power supply module based on the relay in the energized state.

[0040] like Figure 2 As shown, Figure 2 A schematic diagram of an implementation of a relay in a vehicle charging system provided in an embodiment of the present application, in Figure 2 The process in which the relay is in the disconnected state and the relay does not perform the subsequent power transmission operation is shown. Specifically, if the electric energy is in a high-level state, the power supply control module is specifically used to generate a power supply stop signal according to the electric energy in the high-level state, and send the power supply stop signal to the relay, wherein the relay is in a non-attracted state (i.e., disconnected state), and the power supply stop signal is used to instruct the relay to stop performing the power transmission operation. It can be understood that when the relay receives the power supply stop signal transmitted by the power supply control module, the state of the relay is in the disconnected state, thereby stopping the electric energy in the battery from being sent to the vehicle-mounted power supply module. In this way, the power supply control module in the present application can realize unified power supply control for the vehicle, reduce the wiring harness loop, and reduce the hardware cost.

[0041] It should also be noted that in this application, when the vehicle is in energy-saving mode or sleep mode (wherein the energy-saving mode or sleep mode can be set by the user to start the energy-saving mode or sleep mode of the vehicle), the power supply control module in the vehicle charging system can continue to generate a power supply stop signal and send the power supply stop signal to the relay to instruct the relay to stop transmitting power to the vehicle power supply module. In this way, the present application can turn off the charging function of the vehicle power supply module when the vehicle is in energy-saving mode or sleep mode to save vehicle power.

[0042] In an achievable implementation, the vehicle charging system further includes a first ambient light and a second ambient light, the first ambient light is located around the vehicle power supply module, and the second ambient light is located outside the vehicle power supply module, and the location outside the vehicle power supply module includes the vehicle roof, the vehicle instrument panel, the vehicle center armrest, and the vehicle door trim. It can be understood that the first ambient light is located around the vehicle power supply module, which makes it easier for users to clearly find the location of the vehicle power supply module, and the second ambient light is located outside the vehicle power supply module, which can further improve the interaction performance between the vehicle and the user.

[0043] Specifically, the on-board power supply module is connected to the first atmosphere light, and the on-board power supply module is also used to start the first atmosphere light according to the electric energy. The power supply control module is connected to the second atmosphere light, and the power supply control module is also used to start the second atmosphere light according to the electric energy, wherein the first atmosphere light and the second atmosphere light can be breathing light effects, or flash for N seconds, where N is greater than or equal to 1. It can be understood that when the vehicle is started, the on-board power supply module and the power supply control module can start the first atmosphere light and the second atmosphere light according to the electric energy provided by the battery. In this way, compared with the lack of interaction between the vehicle and the user in the related art, the present application can interact with the user by starting the atmosphere light when starting the vehicle, thereby enhancing the user experience.

[0044] It should be noted that the vehicle-mounted power supply module in the present application is also used to send the charging status of the mobile terminal device to the power supply control module, wherein the charging status includes the output voltage and output current output by the vehicle-mounted power supply module to the mobile terminal device, as well as the connection status of the mobile terminal device, the real-time charging power, the initial charging power, the charging time and the final power. The charging status mentioned in this application is only a partial example and is not specifically limited here.

[0045] Furthermore, after the power supply control module receives the charging status transmitted by the vehicle-mounted power supply module, the power supply control module is also used to generate an atmosphere light control signal according to the connection status in the charging status, and send the atmosphere light control signal to the vehicle-mounted power supply module. At this time, the vehicle-mounted power supply module is also used to control the operation of the first atmosphere light according to the atmosphere light control signal transmitted by the power supply control module. And the power supply control module is also used to control the operation of the second atmosphere light according to the connection status in the charging status transmitted by the vehicle-mounted power supply module. It should be noted that the connection status of the mobile terminal device includes the initial connection status (i.e., the initial connection between the vehicle-mounted power supply module and the mobile terminal device, and the mobile terminal device needs to be charged), the connecting status (i.e., the vehicle-mounted power supply module and the mobile terminal device are connected, and the mobile terminal device is charging) and the connection end status (i.e., the connection between the vehicle-mounted power supply module and the mobile terminal device is ended, and the charging of the mobile terminal device is ended).

[0046] Specifically, when the vehicle-mounted power supply module is initially connected to the mobile terminal device, the vehicle-mounted power supply module and the power supply control module can control the operation of the first atmosphere light and the second atmosphere light, wherein the operating state of the first atmosphere light and the second atmosphere light can be that the first atmosphere light and the second atmosphere light are lit in sequence to form a water ripple-like diffused lighting effect.

[0047] When the vehicle-mounted power supply module is connected to the mobile terminal device and provides power to the mobile terminal device, the vehicle-mounted power supply module and the power supply control module can control the operation of the first atmosphere light and the second atmosphere light according to the real-time charging power of the mobile terminal device, wherein the operating state of the first atmosphere light and the second atmosphere light can be to light up the first atmosphere light and the second atmosphere light with a breathing light effect (i.e., different breathing light colors can indicate different charging powers).

[0048] When the connection between the vehicle-mounted power supply module and the mobile terminal device is completed, the vehicle-mounted power supply module and the power supply control module can control the operation of the first atmosphere light and the second atmosphere light according to the real-time charging power of the mobile terminal device, wherein the operating state of the first atmosphere light and the second atmosphere light can be to light up the first atmosphere light and the second atmosphere light with the same color to inform the user that the mobile terminal device is fully charged.

[0049] It should also be noted that the vehicle charging system also includes a sound playing module, and the power supply control module is also used to control the operation of the sound playing module according to the charging state. It can be understood that in this application, the power supply control module can determine whether the vehicle power supply module has an abnormal situation such as a short circuit according to the output voltage and output current in the charging state. If it is determined that the vehicle power supply module has an abnormal situation such as a short circuit, the sound playing module can be enabled to play the sound through the CAN bus, where the CAN bus is a vehicle communication bus, so that the user can be informed of the abnormal situation, thereby improving the user experience to a certain extent.

[0050] It should be further explained that in the present application, the power supply control module can also send the charging status to the on-board intelligent gateway through the CAN bus, so that the on-board intelligent gateway can transmit the charging status to the cloud, so that the cloud can perform further analysis based on the charging status.

[0051] like Figure 3 As shown, Figure 3A schematic diagram of an on-board power supply module in an on-board charging system provided in an embodiment of the present application. The on-board power supply module includes an on-board charging socket, a wireless charging device and an on-board charging interface, wherein the vehicle charging socket includes a 12V (volt) vehicle charging socket and a 220V (volt) AC socket, and the on-board charging interface includes a USB interface and a TYPEC interface. It should be noted that in the present application, the rated power of the 12V vehicle charging socket can be 120W (watt) and the rated current can be 10A, and the configuration quantity can be 2; the rated power of the 220V AC socket can be 150W and the rated current can be 12A, and the configuration quantity can be 1; the rated power of the on-board charging interface can be 18W and the rated current can be 1.5A, and the configuration quantity can be 4; the rated power of the wireless charging device can be 50W and the rated current can be 5A, and the configuration quantity can be 1.

[0052] like Figure 4 As shown, Figure 4 An overall schematic diagram of an on-board charging system in an on-board charging system provided in an embodiment of the present application. Specifically, in the present application, when the vehicle is started, the battery can send the battery terminal power to the relay and the power supply control module, and thereafter when the relay receives the power supply start signal transmitted by the power supply control module, the relay can transmit the power to the on-board power supply module, and at the same time, the power supply control module and the on-board power supply module can start the first atmosphere light and the second atmosphere light, and can control the operation of the first atmosphere light and the second atmosphere light according to the charging status output by the on-board power supply module.

[0053] And in this application, the power supply control module can also upload the charging status to the on-board intelligent gateway, and the on-board intelligent gateway can return a message of successful upload to the power supply control module, and the power supply control module can also control the operation of the sound playback module according to the charging status, and the sound playback module can return a message of successful sound playback to the power supply control module. In this way, in this application, under the action of the power supply control module, the risk of error in the on-board power supply can be avoided to a certain extent, thereby improving the power supply management performance of the vehicle.

[0054] It can be seen that in this optional solution, it is proposed that the power supply start signal generated by the power supply control module can be used to enable the relay to transmit electric energy to the on-board power supply module, and the on-board power supply module can then charge the mobile terminal device based on the electric energy obtained. In this way, the power supply control module in the technical solution of this application can realize the power supply control of the on-board power supply module, that is, the on-board power supply module can obtain electric energy only after the power supply control module outputs the power supply start signal, and the on-board power supply module can provide charging services for the mobile terminal device, thereby avoiding the risk of errors in the on-board power supply to a certain extent, and thus improving the power supply management performance of the vehicle.

[0055] In addition, the present invention also discloses a vehicle, including an on-board charging system, and the on-board charging system is the on-board charging system disclosed in the above embodiment. Therefore, the vehicle with the on-board charging system also has all the above-mentioned technical effects, which will not be repeated here.

The same or similar parts between the embodiments can be referred to in detail. It should be noted that the "first" and "second" (if any) mentioned in the embodiments of this application are only used as name identifiers and do not represent the first or second in order.

[0057] The above is a detailed introduction to a vehicle-mounted charging system and a vehicle provided by the present application.
