[0009] The controller is used to control the first power supply component to charge the user device through the charging component according to the device information and the reserved charging period.

[0010] In the above technical solution, when multiple charging components are connected to multiple user devices, through the collaborative processing of the controller, communication component, and first power supply component, the automatic switching of the charging process of multiple charging components can be realized, which is beneficial to saving the switching time of the charging device during the switching of user devices and improving the charging efficiency of the charging device for multiple user devices. The controller in the charging device can also communicate with the user devices connected to the charging components through the communication component to obtain the device information and reserved charging time periods of the user devices, so that the controller can reasonably arrange the charging order of multiple user devices, avoid some user devices in urgent need of charging waiting for too long, and at the same time, for user devices with less urgent charging needs, optional charging time periods of a relatively valley type can be provided for the user devices to save the charging costs of the user devices and improve the user experience.

[0011] In a possible implementation manner, the number of user devices is M, where M is a positive integer greater than 1 and less than or equal to the number of multiple charging components; the controller is specifically configured to:

[0015] In the above technical solution, the controller of the charging device can determine the charging order of M user devices according to the reserved charging time periods of M user devices, so that the controller can sequentially control the first power supply component to charge M user devices through M charging components according to the charging order and the charging parameters of each user device, avoiding the situation where multiple user devices compete for charging resources when there are multiple user devices, which is beneficial to realizing the reasonable allocation of resources of the charging device, improving the resource utilization rate of the charging device, reducing the charging waiting time of user devices, enabling the charging device to provide charging services for more user devices within a unit time (for example, one day), and being beneficial to improving the charging efficiency of the charging device.

These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0155] First, in combination with Figures 2 to 5 , the structure of the charging device provided by the embodiment of the present application will be described in detail.

[0156] Figure 2 is one of the structural schematic diagrams of the charging device provided by the embodiment of the present application. Please refer to Figure 2 , the charging device 10 may include multiple charging components 101, a communication component 102, a controller 103, and a first power supply component 104, wherein:

[0157] The charging component can be used to connect to user devices. For example, multiple charging components 101 include charging component 1 to charging component 4, and multiple user devices 20 include user device 1 to user device 4. Among them, charging component 1 is connected to user device 1, charging component 2 is connected to user device 2, charging component 3 is connected to user device 3, and charging component 4 is connected to user device 4.

[0158] The communication component 102 is also respectively connected to each charging component;

[0159] The controller 103 is respectively connected to the communication component 102 and the first power supply component 104;

[0160] The first power supply component 1034 is also respectively connected to each charging component, and the first power supply component 104 is also used to connect to the power supply 30.

[0161] It should be noted that the communication component 102, the controller 103, and the first power supply component 104 provided in the embodiments of the present application can be coupled to Figure 1 the charging pile shown. Among them, the power supply component 1041 can be coupled to the power distribution unit in the charging pile; the controller 103 can be coupled in the charging control unit in the charging pile; the communication component 102 can be coupled in the charging fee control unit. The charging component can be Figure 1 the charging gun shown.

[0162] For the charging device provided in the embodiments of the present application, when multiple charging components are connected to multiple user devices, through the collaborative processing of the controller, the communication component, and the first power supply component, the automatic switching charging process of multiple charging components can be realized, which is beneficial to saving the switching time of the charging device during the switching of user devices and improving the charging efficiency of the charging device for multiple user devices. The controller in the charging device can also communicate with the user devices connected to the charging components through the communication component to obtain the device information and reserved charging time periods of the user devices, so as to facilitate the controller to reasonably arrange the charging order of multiple user devices, avoid the waiting time of some user devices in urgent need of charging from being too long, and is beneficial to improving the user experience.

[0163] In some embodiments, based on Figure 2 the structure of the charging device shown, the charging device 10 can also include a second power supply component 105.

[0164] Figure 3 This is the second structural schematic diagram of the charging device provided in the embodiments of the present application. Please refer to Figure 3 , in Figure 2Based on the structure of the charging device shown, the charging device 10 may further include a second power supply component 105. The second power supply component 105 may be respectively connected to the controller 103 and the communication component 102, and the second power supply component 105 may be used to supply power to the controller 103 and the communication component 102.

[0165] It should be noted that the second power supply component 105 provided in the embodiments of the present application may be coupled to Figure 1 the power distribution unit in the charging pile shown.

[0166] By providing the first power supply component and the second power supply component, the charging device provided in the embodiments of the present application can isolate the power supply paths of the controller and the communication component from the power supply path of the charging device for the user device. When the first power supply component fails, the controller and the communication component can still work normally under the action of the second power supply component, which is convenient for the controller to cut off the power supply process of the charging device to the user device in time in some abnormal situations, so as to ensure the stability and safety of the power supply of the charging device.

[0167] Please refer to Figure 3 , the first power supply component 104 may further include a power supply component 1041 and a power distribution component 1042, where: the power supply component 1041 is respectively connected to the controller 103 and the power distribution component 1042, and the power supply component 1041 is also used to be connected to the power supply 30; the power distribution component 1042 is also respectively connected to the controller 103 and each of the multiple charging components 101.

[0168] By splitting the first power supply component into a power supply component and a power distribution component, the charging device provided in the embodiments of the present application can separate the power conversion process and the power distribution process, so as to avoid the mutual influence of these two processes, enabling the controller to more safely and conveniently implement the charging switching process of multiple charging components.

[0169] In the charging device provided in the embodiments of the present application, the arrangement manner of the power supply component and the power distribution component is not limited. The power supply component 1041 and the power distribution component 1042 may be coupled as the first power supply component and then set in Figure 1 the power distribution unit in the charging pile shown; or, the power supply component 1041 and the power distribution component 1042 may be set as two independent components in the power distribution unit of the charging pile; or, as Figure 4 shown, the power supply component 1041 may be coupled in the power distribution unit of the charging pile, and the power distribution component 1042 may be independently set outside the charging pile.

[0171] In the embodiment of the present application, the charging device provided can make the power distribution component independent of the charging pile, making the configuration method of the charging pile more flexible.

[0172] Figure 5 This is the fourth structural schematic diagram of the charging device provided by the embodiment of the present application. Please refer to Figure 5 , the charging device 10 may be set as an integrated charging device, which may include a plurality of charging components 101, a communication component 102, a controller 103, a power supply component 1041, a power distribution component 1042, and a second power component 105.

The embodiment of the present application does not limit the arrangement method of the controller 103 and the communication component 102 in the charging device 10.

[0174] The number of the power supply components 1041 and the number of the second power components 105 may be one or more. The power supply components 1041 and the second power components 105 are also used to connect to the power supply 30, and the power supply 30 may be the power supply provided by the municipal power grid.

[0175] Each power supply component may include a set of power supply lines.

Among them, the positive power supply line may be respectively connected to the positive connection end of the power supply 30 and the positive connection end of the control module, the negative power supply line may be respectively connected to the negative connection end of the power supply 30 and the negative connection end of the control module, and the grounding line may be used for grounding.

[0176] Similarly, each second power component may include a set of power supply lines. Each set of power supply lines may include a positive power supply line, a negative power supply line, and a grounding line. Among them, the positive power supply line may be respectively connected to the positive connection end of the power supply 30 and the positive connection end of the control module, the negative power supply line may be respectively connected to the negative connection end of the power supply 30 and the negative connection end of the control module, and the grounding line may be used for grounding.

[0177] The charging device 10 may further be provided with a collector 106, which may be arranged between the control module and the power distribution component 1042. The collector 106 may include an ammeter and a shunt, and the collector 106 may be used to collect the current and / or voltage of the charging device.

[0178] The charging device may further be provided with a fuse (FU2) 107, which may be arranged between the collector 106 and the power distribution component 1042, and the fuse 107 may be used to ensure the safety of the power supply of the charging device.

[0183] Next, the functions of the components in the above charging device will be described in detail.

[0184] (1) Multiple charging components 101

[0185] For any one of the multiple charging components 101, the charging component can be configured with an independent control circuit and a communication module. After the charging component is connected to the user device 20, connection indication information can be sent to the controller 103 through the communication module, and the connection indication information is used to notify the control 103 that the charging component has been connected to the user device 20. The control circuit can be used to control the connection state between the charging component and the user device. For example, in some charging abnormal scenarios (such as overvoltage, overcurrent, or overheating, etc.), the connection relationship between the charging component and the user device can be cut off based on the control circuit to ensure the charging safety of the charging device and the user device.

[0186] In the actual application process, the connection states of the multiple charging components 101 can all be connected. In this case, each charging component of the charging device is connected to a user device; or, the connection states of some of the multiple charging components 101 are connected, and the connection states of the other part of the charging components are not connected. In this case, only a part of the charging components of the charging device are connected to the user device; or, the connection states of all the multiple charging components 101 are not connected. In this case, each charging component of the charging device is not connected to the user device.

[0187] Exemplarily, the charging component can be a charging gun, a charging plug, or a charging interface, and the user device can be an electric vehicle or other devices that can be charged through a charging pile.

[0188] (2) Communication component 102

[0189] The communication component 102 can be used to obtain the device information of the user device connected to the charging component and the reserved charging period, and send the device information and the reserved charging period to the controller.

[0190] The device information can include the device identifier, device type, device name, the power information of the battery in the user device, and charging parameters. The power information can include parameters such as the maximum capacity, current capacity, voltage, and the ratio of the current capacity to the maximum capacity of the battery. The charging parameters can include parameters such as the charging mode, charging power, and charging duration of the battery.

[0191] It can be understood that after the charging component is connected to the user device, the communication component 102 can be used to realize the communication between the controller 103 and the user device connected to the charging component, so that the controller 103 can obtain the device information and the reserved charging period of the user device, and more accurately control the charging process of the charging device 10 for the user device through the device information and the reserved charging period of the user device.

[0192] In one embodiment, the process by which the communication component 102 obtains the device information of the user equipment connected to each charging component and the reserved charging period is the same. It should be noted that for any one of the multiple charging components, the process by which the communication component 102 obtains the device information of the user equipment connected to the charging component and the reserved charging period will be described in detail in the Figure 7 embodiment.

[0193] Exemplarily, the communication component may be a Telematics Control Unit (TCU).

[0194] (3) Controller 103

[0195] The controller 103 can be used to control the first power supply component to charge the user equipment through the charging component according to the device information and the reserved charging period.

[0196] The controller 103 can accurately control the charging process of the charging device 10 for the user equipment through the communication component 102 and the first power supply component 103. It should be noted that the specific control process of the controller will be described in detail in the Figure 9 embodiment.

[0197] In some embodiments, the controller 103 and the communication component 102 can be integrally arranged as a control module. The control module can be used to obtain the device information of the user equipment connected to the charging component and the reserved charging period, and control the first power supply component to charge the user equipment through the charging component according to the device information and the reserved charging period of the user equipment.

[0198] In some embodiments, the controller may adopt an intelligent recommendation algorithm to configure personalized charging strategies for each user equipment according to factors such as the charging requirements of the user equipment, device information (for example, the remaining power and battery health status of the battery of the user equipment), grid load, and electricity price information at different charging periods, so that the user can quickly determine the charging configuration information of the user equipment based on the charging strategy through the user equipment or the target client corresponding to the user equipment.

[0199] Optionally, the controller may configure the charging parameters of the user equipment according to the vehicle information of the electric vehicle. The controller may also recommend the most suitable reserved charging period for the user equipment among multiple optional charging periods according to the charging requirements of the user equipment. For example, for user equipment with relatively urgent charging requirements, the earliest optional charging period among multiple optional charging periods is provided so that these user equipment can be charged preferentially; the types corresponding to the optional charging periods may include peak types, valley types, and flat types. It can be understood that the electricity prices corresponding to each type are, from high to low: peak type > flat type > valley type. For user equipment with non-urgent charging requirements, the valley type of optional charging period can be provided for the user equipment to save the charging cost of the user equipment.

[0200] (4) The first power supply component 104

[0201] The first power supply component 104 can be used to convert the output voltage of the power supply 30 into the working voltage required by each charging component under the control of the controller 103, and charge the user equipment connected to each charging component based on this working voltage.

[0202] The first power supply component 104 may include a power supply component 1041 and a power distribution component 1042, where:

[0203] The power supply component 1041 can be used to receive the charging control instruction sent by the controller 103, convert the output voltage of the power supply 30 into the working voltage required by the charging component based on this charging control instruction, and input this working voltage to the power distribution component 1042.

[0204] In some embodiments, the power supply component 1041 may include a three-phase power factor correction (PFC) converter and a high-frequency direct current (DC) / DC converter. Among them, the three-phase PFC converter can be used to improve the power factor of the power supply, and the high-frequency DC / DC converter can be used to achieve the voltage conversion of the power supply.

[0205] In some embodiments, the power supply component 1041 can be used to provide direct current or alternating current power for the user equipment connected to the charging component. The power supply component 1041 can have functions such as overvoltage protection, overcurrent protection, and short-circuit protection to ensure the stability and safety of the power supply of the power supply component 1041.

[0206] The power distribution component 1042 can be used to receive the distribution control instruction sent by the controller, and based on the charging sequence of multiple charging components indicated in the distribution control instruction, implement the charging switching process for the multiple charging components. In some embodiments, the power distribution component 1042 can be a power distribution unit (PDU) with timing function.

[0207] Assume that the multiple charging components can include a first charging component and a second charging component. The first charging component is connected to a first user device, and the second charging component is connected to a second user device. The power distribution component 1042 can receive the distribution control instruction of the controller 103. The distribution control instruction can be used to instruct the power distribution component 1042 to supply power to the first charging component at the first moment, stop supplying power to the first charging component at the second moment, and supply power to the second charging component at the third moment. At the first moment, the power distribution component 1042 can input the operating voltage of the first user device output by the power supply component 1041 to the first charging component to charge the first user device through the first charging component; at the second moment, the power distribution component 1042 can stop charging the first charging component; at the third moment, the power distribution component 1042 can input the operating voltage of the second user device output by the power supply component 1041 to the second charging component to charge the second user device through the second charging component.

[0208] (5) The second power supply component 105

[0209] The second power supply component 105 can also be used to connect to the power supply 30. The second power supply component 105 can be used to convert the output voltage of the power supply into the operating voltage of the controller 103 and the operating voltage of the communication component 102.

[0210] In some embodiments, the second power supply component 105 can be used to provide DC power for the controller 103 and the communication component 102. The second power supply component 105 can have functions such as overvoltage protection, overcurrent protection, and short-circuit protection to ensure the stability and safety of the power supply of the second power supply component 105.

[0211] In some embodiments, when designing the charging device, the number M of user devices that the charging device can support per unit time can be determined according to the actual power output of the charging device, the average charging power or average charging duration of the user device per unit time. The charging device needs to be provided with M charging components, and the controller in the charging device needs to support the charging control functions of M user devices corresponding to the M charging components, and the communication component needs to support the communication services of M user devices, so that the reservation charging service of the charging device can cover more user devices. The charging control function means that the charging device can configure the charging parameters of each user device and determine the charging order of each user device according to the device information and reservation charging period of each user device, and control the first power component to charge the corresponding user device through the charging component according to the charging parameters and charging order. The communication service may include: obtaining the device information and reservation charging period of the user device connected to the charging device through the charging component; providing the charging instruction information of the charging device to the user device or the target client corresponding to the user device; obtaining the charging configuration information of the user device.

[0212] For example, the actual power output of the charging pile is 120 kW, the unit time is set to 1 day. Assuming that the average charging power of each electric vehicle per day is 60 kW, then the average charging duration of each electric vehicle is 0.5 hours. Assuming that the working hours of the charging pile in a day are 24 hours, the charging device can provide sorting charging services for 48 electric vehicles in 48 parking spaces per unit time. The controller of the charging device can support the charging control functions of 48 user devices, and the communication component needs to support the communication services of 48 user devices.

[0213] The charging device provided by the embodiments of the present application is beneficial to saving the switching duration during the switching of charging for multiple user devices and improving the charging efficiency of the charging device for multiple user devices. Moreover, the charging device can also obtain the device information and reservation charging period of the user device, and configure the charging order for the user based on the device information and reservation charging period of the user device, avoiding too long waiting time for some user devices in urgent need of charging, which is beneficial to improving the user experience.

[0214] Based on the structure of the above charging device, the embodiments of the present application further provide a software architecture diagram of the charging device.

[0215] Figure 6 For the schematic diagram of the software architecture of the charging device provided by the embodiments of the present application, please refer to Figure 6 , a management system can be deployed in the charging device 10. The management system can include a user interface layer, a business logic layer, and a hardware control layer, where:

[0216] (1) User interface layer

[0217] The user interface layer can be used to implement the communication interaction process between the management system and the user device connected to the charging device or the target client corresponding to the user device. The target client can be a client used by the user to manage the user device. For example, the target client can be an application (APP) for electric vehicle charging management on the user's mobile phone.

[0218] In some embodiments, the user interface layer can be used to provide an information display interface, which can be used to display the charging indication information of the charging device and the charging status information of the user device. The user can view the charging indication information of the charging device and the charging status information of the user device displayed in the information display interface through the user device or the target client, and input charging configuration information to the user interface layer through the setting control in the information display interface.

[0219] The charging indication information can include at least one optional charging period of the charging device at the current moment, and the charging cost of each optional charging period. The charging indication information can also include the type corresponding to each optional charging period, the working state of the charging device (abnormal state or normal operation state), the maximum number of user devices preset by the charging device, the number of user devices already connected at the current moment and the charging queuing order among these user devices, the number of user devices that can still be connected at the current moment, etc.

[0220] It can be understood that the charging periods can be divided into three types according to the amount of electricity consumption: peak type, valley type, and flat type. When the type of the charging period is the peak type, it means that the minimum value of the electricity consumption in this charging period is greater than the maximum value of the average electricity consumption range; when the type of the charging period is the flat type, it means that the electricity consumption in this charging period is within the average electricity consumption range; when the type of the charging period is the valley type, it means that the maximum value of the electricity consumption in this charging period is less than the minimum value of the average electricity consumption range. The charging cost of the charging device can change with the change of the type of the charging period. For example, when the charging period is the peak type, the charging cost is the highest; when the charging period is the valley type, the charging cost is the lowest; when the charging period is the flat type, the charging cost of the valley type < the charging cost of the flat type < the charging cost of the peak type.

[0221] The charging status information can include the current charging progress, the charged duration, and the remaining charging duration of the user device, etc. During the process of the charging device charging the user device, the charging device can provide the charging status information of the user device to the user in real time based on this information display interface, so as to facilitate the user to timely understand the charging progress of the user device.

[0222] The charging configuration information can be used to determine the reserved charging period of the user device.

[0223] At present, there are many charging devices with unreasonable resource allocation. For example, during the peak electricity consumption period (peak time), there may be a situation where multiple user devices queue up to wait for charging, resulting in the charging resources of the charging device being difficult to meet the charging needs of multiple user devices; during the low electricity consumption period (valley time), there may be a situation where the charging device is idle, resulting in the waste of the charging resources of the charging device.

[0224] The charging device provided by the embodiment of the present application can be used to solve the above problems. The charging device can provide an information display interface to the user through the user interface layer to provide a reservation charging service to the user, so that the user can reasonably configure charging configuration information such as the reserved charging period of the user device according to their own time arrangement, as well as the selectable charging periods and charging fees in the charging indication information, so that it is more economical and reasonable when charging the user device. For example, when the user does not use the user device temporarily, the user can reserve a valley-type selectable charging period to charge the user device to reduce the charging cost of the user device.

[0225] Different user devices can reserve different charging periods of the charging device, so that the charging device provides charging services to different user devices at different time periods, which is conducive to making full use of the working time of the charging device and avoiding the waste of the resources of the charging device caused by the idleness of the charging device during the valley time. By providing charging services for different types of charging periods, the charging device can facilitate the user to charge the user device during the valley time, which is conducive to balancing the power supply load of the power grid, making full use of the surplus power in the power grid, improving the energy utilization efficiency and operation efficiency of the power grid, reducing energy waste, and realizing the sustainable utilization of energy.

[0226] Through the reserved charging periods of each user device, it is convenient for the charging device to sort the user devices that have reserved charging during the peak time and charge each user device in turn according to the sorting result, avoiding the situation where multiple user devices compete for charging resources (such as charging power), which is conducive to realizing the reasonable allocation of the resources of the charging device, improving the resource utilization rate of the charging device, reducing the charging waiting time of the user device, so that the charging device can provide charging services to more user devices within a unit time (such as one day), which is conducive to improving the charging efficiency of the charging device.

[0227] (2) Hardware control layer

[0228] The hardware control layer can be used for the management system to interact with each hardware device of the charging device.

[0229] The hardware control layer can be used to receive control instructions sent by the service logic layer and control the working processes of the hardware components in the charging device based on the control instructions. For example, the hardware components can include a charging component. The hardware control layer can receive the control instructions of the charging component sent by the service logic layer and control the on / off of the charging component based on the control instructions of the charging component. The hardware components can also include a power supply component. The hardware control layer can receive the control instructions of the power supply component sent by the service logic layer and control the power output and working status of the power supply component based on the control instructions of the power supply component.

[0230] The hardware control layer can also be used to obtain device information sent by the hardware components and feedback the device information to the service logic layer. The device information can include the device information of the hardware components themselves and the device information of the user device collected by the hardware components. The device information of the hardware components themselves can include the identification, model, and working status of the device. The device information of the user device can include the device identification, device type, device name, battery power information, and charging parameters of the user device.

[0231] (3) Service logic layer

[0232] The service logic layer can be used to obtain the device information sent by the hardware control layer and send control instructions to the hardware control layer to control the working processes of the hardware components in the charging device through the control instructions.

[0233] The service logic layer can also be used to obtain the charging configuration information sent by the user interface layer and determine the control instructions of the hardware components of the charging device based on the charging configuration information and the device information.

[0234] Based on the above charging device, an embodiment of the present application further provides a charging control method. Next, in combination with Figures 7 to 9 , the charging control method will be described in detail.

[0235] For any one of the multiple charging components, the charging device 10 can refer to the charging control method shown in Figure 7 and obtain the device information and reserved charging period of the user device connected to the charging component through the communication component.

[0236] Figure 7 One of the flow diagrams of the charging control method provided by an embodiment of the present application is shown in Figure 7 . The method can be executed by the communication component in the charging device. The method can specifically include the following steps:

[0237] S701. After the charging component is connected to the user device, request the user device to obtain the device information of the user device.

[0238] The device information may include the device identifier, device type, device name, power information of the battery in the user device, and charging parameters. The power information may include parameters such as the maximum capacity, current capacity, voltage, and the ratio of the current capacity to the maximum capacity of the battery. The charging parameters may include parameters such as the charging mode and charging power of the battery.

[0239] In some embodiments, a device management system may be provided in the user device. The device management system may include a Battery Management System (BMS). After the charging device is connected to the user device, the charging device may request to establish a communication connection with the device management system in the user device through the communication component, and after the communication connection is successfully established, request the device management system to obtain the device information of the user device.

[0240] S702. Send the charging instruction information of the charging device to the target client.

[0241] The target client may be the client corresponding to the user device. Optionally, the target client may be the device management system of the user device, or the target client may also be the client used by the user to manage the user device. For example, the APP for user device management in the mobile phone.

[0242] The charging instruction information includes the optional charging time periods of the charging device at the current moment and the charging fees for the optional charging time periods. The number of the optional charging time periods may be one or more.

[0243] The charging instruction information may further include the types corresponding to the optional charging time periods (peak type, valley type, and flat type), the working state of the charging device (abnormal state or normal operation state), the maximum number of user devices preset by the charging device, the number of user devices already connected at the current moment and the charging queue order among these user devices, the number of user devices that can still be connected at the current moment, etc.

[0244] In some embodiments, the communication component may also display the charging instruction information to the target client based on the information display interface provided by the user interface layer of the charging device.

[0245] S703. Receive the charging configuration information of the user device sent by the target client.

[0246] The charging configuration information may be determined based on the charging instruction information.

[0247] In some embodiments, the charging configuration information may include the indication information of the reserved charging time period and the charging mode of the user device.

[0248] The indication information of the reserved charging period may include: the start time and end time of charging of the user device; or, the start time and charging duration of the user device; or, the end time and charging duration of the user device.

[0249] Exemplarily, the charging mode may include a supercharging mode, a fast charging mode, a normal mode, an energy-saving mode, etc.

[0250] In some embodiments, the communication component may establish a communication connection with the target client based on the information display interface provided by the user interface layer of the charging device, so as to obtain the charging configuration information sent by the target client.

[0251] S704. Determine the reserved charging period of the user device according to the charging configuration information.

[0252] In some embodiments, the communication component may determine the reserved charging period of the user device based on the indication information of the reserved charging period in the charging configuration information.

[0253] In some embodiments, during the process of charging the user device by the charging device, the communication component may also be used to request the target client to obtain the real-time charging information of the battery of the user device, and send the real-time charging information to the controller, so that the controller can implement precise control of the charging of the user device based on the real-time charging information.

[0254] The charging control method provided by the embodiments of the present application enables the charging device to provide charging services for different types of charging periods, so that users can reasonably configure charging configuration information such as the reserved charging period of the user device according to their own time arrangements, as well as the optional charging periods and charging fees in the charging indication information, making the charging of the user device more economical and reasonable. Moreover, the charging control method can encourage users to charge the user device during off-peak periods, which is beneficial to balancing the power supply load of the power grid, making full use of the surplus power in the power grid, improving the energy utilization efficiency and operation efficiency of the power grid, reducing energy waste, and realizing the sustainable utilization of energy. By obtaining the reserved charging periods of each user device, it is convenient for the charging device to sort the user devices that have reserved charging during peak periods, and charge each user device in sequence according to the sorting result, avoiding the situation where multiple user devices compete for charging resources; it can also avoid the situation where the charging device is idle during off-peak periods, resulting in waste of the resources of the charging device, which is beneficial to realizing the reasonable allocation of the resources of the charging device, improving the resource utilization rate of the charging device and the charging efficiency of the charging device.

[0255] In some embodiments, the controller may also be used to control the communication component to obtain the device information and the reserved charging period of the user device. Next, in combination with Figure 8 , this process will be described in detail.

[0256] Figure 8 This is the second flowchart of the charging control method provided by the embodiments of the present application. Please refer to Figure 8 This method can be executed by a controller in the charging device. Specifically, this method may include the following steps:

[0257] S801. Obtain the connection status of multiple charging components.

[0258] The connection status includes connected and not connected.

[0259] The connection status can be used to indicate the connection relationship between the charging component and the user device. If the connection status is connected, it means that the charging component is successfully connected to the user device; if the connection status is not connected, it means that the charging component is not connected to the user device or the connection fails.

[0260] S802. When there is a target charging component among the multiple charging components, send an information collection instruction to the communication component.

[0261] Among them, the connection status of the target charging component is connected, and the number of target charging components can be one or more.

[0262] The information collection instruction can be used to instruct the communication component to obtain the device information and the reserved charging period of the user device connected to the target charging component. The communication component can respond to this information collection instruction and obtain the device information and the reserved charging period of this user device according to the method shown in steps S701 - S704.

[0263] For the charging control method provided by the embodiments of the present application, the controller in the charging device can timely obtain the connection status of each charging component, so that after each charging component is connected to the user device, it can timely obtain the device information and the reserved charging period of the user device connected to the charging component, so as to timely update the charging indication information in the charging device and provide more accurate charging indication information for the subsequent user devices to be connected to this charging device.

[0264] In some embodiments, assume that the number of user devices connected to the charging device 10 is M, where M is a positive integer greater than 1 and less than or equal to the number of multiple charging components. For example, if the number of multiple charging components of the charging device is 24, then 1 < M ≤ 24. In this case, the charging device can refer to Figure 9 the charging control method shown in

[0265] Figure 9 This is the third flowchart of the charging control method provided by the embodiments of the present application. Please refer to Figure 9, this method can be executed by the controller in the charging device, and the method can specifically include the following steps:

[0266] S901. Determine the charging parameters of each user device according to the device information of each user device.

[0267] In some embodiments, the device information may include the charging parameters of the battery in the user device. The controller can extract the charging parameters from the device information, and the charging parameters may include at least one of the following: the charging mode of the battery, the charging power, the charging voltage, and the charging precautions, etc.

[0268] In some embodiments, the controller can also determine the charging parameters of each user device based on the device information and the charging configuration information of each user device.

[0269] For example, the charging parameters may include multiple optional charging modes and the charging power corresponding to each charging mode. If the user does not configure the charging mode of the user device in the charging configuration information, the controller can determine the default charging mode among the multiple optional charging modes or the optional charging mode commonly used by the user device as the charging mode when the charging device charges the user device, and determine the charging power corresponding to the default charging mode as the charging power when the charging device charges the user device. If the user configures the charging mode of the user device in the charging configuration information, then determine the charging mode configured by the user as the charging mode when the charging device charges the user device, and determine the charging power corresponding to the charging mode configured by the user as the charging power when the charging device charges the user device.

[0270] S902. Determine the charging order of the M user devices according to the scheduled charging periods of the M user devices.

[0271] In some embodiments, the charging order of multiple user devices can be determined according to the sequence of the start times or end times of the scheduled charging periods of the M user devices.

[0272] In some embodiments, assume that the start time of the scheduled charging period of the first user device is the same as the start time of the scheduled charging period of the second user device, and / or, the end time of the scheduled charging period of the first user device is the same as the end time of the scheduled charging period of the second user device. The charging order of the first user device and the second user device can be determined according to the serial number of the charging component connected to the first user device and the serial number of the charging component connected to the second user device. For example, the serial number of the charging component connected to the first user device is 5, and the serial number of the charging component connected to the second user device is 3. Assume that the smaller the serial number of the charging component, the earlier the charging order. Then the charging order of the second user device is before the charging order of the first user device.

[0273] In some embodiments, after the controller obtains the scheduled charging period of the user device, the controller can also be used to update the charging indication information of the charging device according to the scheduled charging period of the user device.

[0274] After obtaining the scheduled charging period of the user device, the method can update information such as the selectable charging period in the charging indication information of the charging device in a timely manner, so that after a new user device is connected to the charging device, the target client corresponding to the newly connected user device can accurately select the scheduled charging period based on the updated charging indication information.

[0275] S903. Control the first power supply component to charge M user devices through M charging components according to the charging order and the charging parameters of each user device in the M user devices.

[0276] The M charging components are the charging components connected to the M user devices.

[0277] It should be noted that the process of the controller controlling the first power supply component to charge M user devices through the M charging components will be described in detail in the Figure 10 embodiment.

[0278] For any one charging component, the controller is specifically further used to obtain the first device state of the charging device and the second device state of the user device during the process of the charging device charging the user device through the charging component; in the case where the first device state and / or the second device state is abnormal, control the charging component to stop charging the user device, generate an alarm message, and send the alarm message to the user device.

[0279] The first device state may include the power supply state of the charging device supplying power to the user device, and the power supply state may include a normal state or an abnormal state.

[0280] In some embodiments, the controller can perform the following steps to determine the power supply state: obtain the charging monitoring index of the charging device; if the actual detected value of the charging monitoring index is greater than or equal to the standard value of the charging monitoring index, determine that the power supply state of the charging device is an abnormal state; if the actual detected value of the charging monitoring index is less than the standard value of the charging monitoring index, determine that the power supply state of the charging device is a normal state.

[0281] The charging monitoring index may include at least one of the following: voltage, current, and power supply heat.

[0282] It can be understood that if the power supply state is an abnormal state, it means that overvoltage, overcurrent, or overheating may occur when the charging device charges the user device. In this case, the charging device can immediately stop supplying power to the user device to ensure the power supply safety of the user device and the charging device.

[0283] The second device state may include the battery state of the electrical device, and the battery state may include a normal charging state and an abnormal charging state.

[0284] It can be understood that when the battery state of the user device is abnormal, the charging device can also immediately stop supplying power to the user device to ensure the power supply safety of the user device and the charging device.

[0285] The alarm information can be used to indicate that an abnormal situation occurs during the charging process of the charging device for the user device.

[0286] In this charging control method, the controller of the charging device can monitor the first device state and the second device state in real time during the charging process, so as to, when the first device state and / or the second device state is abnormal, timely send the alarm information to the user through the communication component, so that the user can, based on the alarm information, timely discover the cause of the charging failure of the user device and quickly solve the charging failure, which is beneficial to ensuring the charging safety of the user device.

[0287] For the charging control method provided by the embodiments of the present application, the controller of the charging device can determine the charging order of M user devices according to the reserved charging periods of the M user devices, and control the first power supply component to charge the M user devices through the M charging components in sequence according to the charging order and the charging parameters of each user device, avoiding the situation that multiple user devices scramble for charging resources when there are multiple user devices, which is beneficial to realizing the reasonable allocation of the resources of the charging device, improving the resource utilization rate of the charging device, reducing the charging waiting time of the user device, enabling the charging device to provide charging services for more user devices within a unit time (for example, one day), and being beneficial to improving the charging efficiency of the charging device.

[0288] Figure 10 For the fourth flow chart of the charging control method provided by the embodiments of the present application, please refer to Figure 10 , this method can be executed by the controller in the charging device, and this method can specifically include the following steps:

[0289] S1001. Initialize i to 1.

[0290] S1002. Determine the i-th charging component among the M charging components according to the charging order.

[0291] Wherein, i can take 1, 2,..., M in sequence, and M is a positive integer.

[0292] S1003. Generate an allocation control instruction based on the charging order.

[0293] In some embodiments, the allocation control instruction can be used to indicate the switching moment between at least two of the M charging components.

[0294] In some examples, the allocation control instruction may include: the turn-on moment and turn-off moment of the i-th charging component, and the turn-on moment of the (i + 1)-th charging component.

[0295] S1004. Generate the i-th charging control instruction according to the charging parameters of the i-th user equipment corresponding to the i-th charging component.

[0296] In some embodiments, the charging parameters may include the charging power and charging voltage of the battery. The i-th charging control command can be used to instruct the first power supply component to supply power to the i-th charging component according to the charging power and charging voltage indicated by the charging parameters.

[0297] S1005. Control the first power supply component to charge the i-th user equipment through the i-th charging component according to the i-th charging control instruction and the allocation control instruction.

[0298] In some embodiments, the first power supply component may include a power supply component and a power distribution component. The step S1005 may further include the following steps S10051 and S10052:

[0299] S10051. Send the i-th charging control instruction to the power supply component.

[0300] The i-th charging control instruction can be used to control the power supply component to convert the output voltage of the power supply into the working voltage required by the i-th charging component, and input the working voltage to the power distribution component.

[0301] In some embodiments, the i-th charging control instruction may include: the working voltage of the i-th charging component, and / or, the preset output power of the power supply component.

[0302] S10052. Send the allocation control instruction to the power distribution component.

[0303] The allocation control instruction can be used to control the power distribution component to charge the i-th user equipment through the i-th charging component based on the working voltage.

[0304] Optionally, before charging the M charging components, the controller may send the allocation control instructions for these M charging components to the power distribution component at one time. During the charging process of these M charging components, the power distribution component may perform charging switching processing on these M charging components with reference to the processing timing sequence of the allocation control instructions. Assuming that the charging order of these M charging components is: charging component 1 > charging component 2 >... > charging component M, the allocation control instructions corresponding to these M charging components may be presented in the form of a data table as shown in Table 1.

[0305] Table 1

[0306] Identification of the charging component Turn-on time Turn-off time Charging component 1 T0 T1 Charging component 2 T2 T3 …… …… …… Charging component M Tm-1 Tm

[0307] Optionally, before charging the i-th charging component, the controller may also send the i-th allocation control instruction to the power distribution component. The i-th allocation control instruction may be used to indicate: the turn-on time and turn-off time of the i-th charging component, and the turn-on time of the (i + 1)-th charging component.

[0308] In this charging control method, the controller in the charging device can control the power supply component and the power distribution component to convert the output voltage of the power supply into the working voltage required by each charging component by sending charging control instructions to the power supply component and allocation control instructions to the power distribution component, so that the charging device can charge the user device more accurately.

[0309] S1006. Determine whether i is less than M.

[0310] If yes, execute step S1007;

[0311] If not, execute step S1008.

[0312] S1007. Update i to i + 1.

[0313] After executing step S1007, return to execute step S1002.

[0314] S1008. End the charging process of M user devices.
