[0043] Figure 5 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Existing charging control systems often send a specific power value to the vehicle that does not match the actual output capacity of the charging system, making it impossible for the actual output capacity of the charging control system to meet the vehicle's charging needs. For example, if the specific power value sent by the charging control system exceeds the upper limit of the charging interface's output capacity, the vehicle may determine a charging demand that exceeds the actual output capacity of the charging interface based on the specific power value sent by the charging control system. However, the charging interface cannot output power that matches the demanded power, causing the vehicle to automatically shut down.

[0046] Based on this, this application provides a charging control system, such as... Figure 1 As shown, it includes a charging controller, a power distribution module, multiple power modules, and multiple charging ports. One power module can supply power to one or more charging ports through the power distribution module. Figure 1 The number of power modules and charging ports shown is for illustrative purposes only; the number of power modules and charging ports may vary.

[0047] In this embodiment, after detecting a successful connection between any charging interface in the charging control system and the vehicle, the charging controller first determines the initial available power of the charging interface, which is no greater than the upper limit of the charging interface's output power. Specifically, the available power of the charging interface can be determined based on at least one of the following: the usage status of the power module in the charging control system and the power usage information of other charging guns in the charging system. Then, based on the determined available power, an instruction message is sent to the vehicle connected to the charging pile, causing the vehicle to determine its required power based on the power allocation value in the instruction message and its own charging strategy. The vehicle's required power is no greater than the available power of the charging interface. Upon receiving the required power from the vehicle based on the instruction message, the charging controller controls the power allocation module to allocate the corresponding power to the charging interface, enabling the charging interface to provide electrical energy to the vehicle.

[0048] Furthermore, during the process of the charging interface providing power to the vehicle, the charging controller sends indication messages to the vehicle at preset intervals based on the available power of the charging interface, allowing the vehicle to periodically report its power demand. Since the vehicle's power demand will not exceed the maximum output capacity (available power) of the charging interface, if the difference between the available power of the charging interface and the vehicle's power demand is less than a preset threshold, it is assumed that the vehicle may have a greater power demand. That is, if the available power of the charging interface does not exceed its output power limit and there is still idle power in the charging system, the available power of the charging interface can be increased. Then, a new indication message is sent to the vehicle using the increased available power to release the vehicle's power demand, effectively improving the charging speed. If the difference between the available power of the charging interface and the vehicle's power demand is not less than a preset threshold, it indicates that there is surplus available power at the charging interface. If other charging interfaces have demand, the surplus available power of the charging interface can be allocated to other charging interfaces through the power allocation module, avoiding ineffective power occupation and improving the utilization rate of charging resources.

[0049] This application also provides a charging control method, which can be applied to an electronic device, which can be a charging controller in a charging system. The flowchart of the charging control method is shown below. Figure 2 As shown, it specifically includes:

[0050] S201: When it is detected that the charging interface is successfully connected to the vehicle, determine the current available power of the charging interface, wherein the current available power of the charging interface is not greater than the upper limit of the output power of the charging interface.

[0051] In this embodiment, the connection between the charging interface and the vehicle is determined to be successful when the charging interface is physically connected to the vehicle and a communication connection is established.

[0052] Optionally, the charging controller queries the idle power in the charging system based on the working status of the charging system to which the charging interface belongs, and then determines the current available power of the charging interface based on the idle power in the charging system and the upper limit of the output power of the charging interface. For example, if the currently queried idle power is not greater than the upper limit of the output power of the charging interface, the currently queried idle power can be used as the current available power of the charging interface. If the currently queried idle power is greater than the upper limit of the output power of the charging interface, the portion of the currently queried idle power that does not exceed the upper limit of the output power can be used as the available power of the charging interface.

[0053] In this embodiment, the operating state of the charging system may include at least one of the usage status of the power modules and the power usage information of other charging guns in the charging system. Specifically, at least one of the first power available from the idle power module and the adjustable second power from the target charging interface can be used as the idle power of the charging system. The target charging module is the module whose usage status is in the first state among the power modules. The target charging interface is another charging interface in the charging system, and the difference between the available power of the target charging interface and the power demand of the vehicle connected to the target charging interface is greater than a power threshold.

[0054] In this embodiment, the available power can be the output power allocated by the charging system to the charging interface. The upper limit of output power is the standard output current designed for the charging interface under the expected operating conditions, and is a recommended value set based on the safety and performance of the charging interface and its connecting cables, plugs, and other components. Available power and upper limit of current output are two different parameters of the charging interface.

[0055] S202: Send an instruction message to the vehicle based on the current available power of the charging interface, wherein the instruction information includes the current available power of the charging interface and is used to instruct the vehicle to determine the required power based on the current available power of the charging interface.

[0056] In this embodiment, an indication message can be generated based on the current available power of the charging interface, and then sent to the vehicle. This allows the vehicle to determine its required power based on its charging strategy and the available power in the indication message. The vehicle's required power is not greater than the current available power of the charging interface.

[0057] In this embodiment, after determining the required power, the vehicle can generate a power requirement message based on the required power and then send the power requirement message to the charging controller.

[0058] Optionally, an indication message can be periodically sent to the vehicle based on the current available power of the charging interface, thereby continuously monitoring the vehicle's power demand to meet the vehicle's charging needs.

[0059] S203: Upon receiving the power demand feedback from the vehicle, control the charging interface to output electrical energy to the vehicle according to the power demand feedback from the vehicle.

[0060] In this embodiment, when the charging controller receives the power demand feedback from the vehicle based on the indication message, it can control the charging interface to output the electrical energy corresponding to the power demand. Specifically, it can control the power control module in the charging system to provide the electrical energy corresponding to the power demand to the charging interface, so that the charging interface can charge the vehicle.

[0061] By applying the method provided in the embodiments of this application, the available power sent by the charging system to the vehicle does not exceed the upper limit of the output capacity of the charging interface, enabling the vehicle to determine its own needs based on the available power, and ensuring that the charging interface can meet the charging needs of the vehicle, thereby effectively improving charging efficiency and ensuring the safety and stability of the charging process.

[0062] In one embodiment provided in this application, based on the above-described solution, optionally, the process of determining the current available power of the charging interface includes:

[0063] Obtain the usage status of each power module in the charging system to which the charging interface belongs, and determine the idle power module from each power module;

[0064] The available power of the charging interface is determined based on the first power that the idle power module can provide and the upper limit of the output power of the charging interface.

[0065] In this embodiment, the usage state of each power module includes a first state or a second state. The first state of the power module indicates that the power module can be used, and the second state of the power module indicates that the power module cannot be used. In some embodiments, the first state may further include an idle state or an enabled and exitable state; the second state may further include an occupied and disabled state or an enabled and non-exitable state.

[0066] Optionally, the charging controller can identify one or more idle power modules among the power modules based on their usage status.

[0067] In some embodiments, when an idle power module is identified, its usage state can be switched from idle to occupied and disabled to prevent it from being occupied by other charging ports. After receiving the vehicle's power demand, the charging controller can control the idle power module to provide the charging port with the electrical energy corresponding to the demand power through the power distribution module. At this time, the idle power module is in an enabled and non-disabled state.

[0068] In one embodiment provided in this application, based on the above-described scheme, optionally, the current available power of the charging interface is determined according to the first power provided by the idle power module and the upper limit of the output power of the charging interface, including:

[0069] If the first power that the idle power module can provide is not less than the upper limit of the output power of the charging interface, the upper limit of the output power of the charging interface is determined as the current available power of the charging interface;

[0070] If the first power provided by the idle power module is less than the upper limit of the output power of the charging interface, the target charging interface is selected from the other charging interfaces in the charging system; the current available power of the charging interface is determined based on the first power provided by the idle power module, the second power that the target charging interface can be configured with, and the upper limit of the output power of the charging interface.

[0071] In this embodiment, the first power provided by the idle power module can be compared with the upper limit of the output power of the charging interface. If the first power of the idle power module is not less than the upper limit of the output power of the charging interface, the upper limit of the output power can be determined as the current available power of the charging interface. If the first power of the idle power module is less than the upper limit of the output power of the charging interface, the current available power of the charging interface can be determined based on the first power, the second power and the upper limit of the output power, and the current available power of the charging interface is not greater than the upper limit of the output power.

[0072] In this embodiment, the available power of the charging interface can be prevented from exceeding the upper limit of the output power, effectively ensuring the safety of the charging system. Furthermore, when the first power of the idle power module is insufficient to meet the output demand of the charging interface, additional power is allocated from other charging interfaces, which makes the resources in the entire charging system more rationally allocated.

[0073] In one embodiment provided in this application, based on the above-described solution, optionally, the target charging interface is selected from other charging interfaces of the charging system, including:

[0074] For each other charging interface in the charging system, determine the power difference between the available power of the other charging interface and the power required by the vehicle connected to the other charging interface; if the power difference is not less than the power threshold corresponding to the other charging interface, the other charging interface is determined as the target charging interface.

[0075] In this embodiment, the power threshold can be set based on the minimum adjustable power of the target charging interface, and the power thresholds corresponding to each charging pile in the charging system can be the same or different.

[0076] Optionally, the number of target charging ports can be one or more.

[0077] In this embodiment, by selecting a suitable target charging interface from other charging interfaces in the charging system, the available power margin of the target charging interface can be allocated to that charging interface, effectively optimizing the resource allocation of the entire charging system and improving the service quality and user experience when multiple users share charging facilities.

[0078] In one embodiment provided in this application, based on the above-described scheme, optionally, the available power of the charging interface is determined according to the first power provided by the idle power module, the second power adjustable by the target charging interface, and the upper limit of the output power of the charging interface, including:

[0079] If the sum of the first power and the second power that can be adjusted by the target charging interface is less than the upper limit of the output power of the charging interface, then the sum of the first power and the second power is determined as the current available power of the charging interface.

[0080] If the sum of the first power and the second power that can be adjusted by the target charging interface is not less than the upper limit of the output power of the charging interface, then the upper limit of the output power of the charging interface is determined as the current available power of the charging interface.

[0081] In this embodiment, when the sum of the first power and the second power is less than the upper limit of the output power, the sum of the two is set as the available power, which makes full use of the power output capability of the charging system and avoids power waste. If the sum of the two reaches or exceeds the upper limit of the output power, the available power is limited within the upper limit of the output power to prevent overload risk and protect the safety of the charging interface and the connected vehicle.

[0082] By applying the method provided in the embodiments of this application, the charging task can be completed as efficiently as possible without exceeding the upper limit of the output power, thereby improving the speed and efficiency of the charging process.

[0083] In one embodiment provided in this application, based on the above-described solution, optionally, after controlling the charging interface to output electrical energy to the vehicle according to the power demand feedback from the vehicle, the method further includes:

[0084] If the difference between available power and required power is less than the difference threshold, and if idle power is detected in the charging system to which the charging interface belongs, and the available power has not reached the upper limit of the output power of the charging interface, then the available power will be increased.

[0085] A new instruction message is sent to the vehicle based on the increased available power.

[0086] In this embodiment, after receiving the power demand feedback from the vehicle, it can be detected whether the difference between the current available power of the charging interface and the demanded power is less than a difference threshold. If the difference is less than the threshold, it indicates that the vehicle may have a greater power demand. In this case, if the current available power of the charging interface is less than the upper limit of its output power, the idle power in the charging system is re-queried. If idle power is found in the charging system, the available power of the charging interface can be increased using the currently available idle power. The increased available power of the charging interface does not exceed the upper limit of its output power.

[0087] Optionally, the charging controller can send a new instruction message to the vehicle based on the increased available power, thereby controlling the charging interface to output electrical energy to the vehicle according to the vehicle's power demand feedback based on the increased available power.

[0088] By applying the method provided in the embodiments of this application, the optimal utilization of charging power resources can be achieved, while ensuring the safety and stability of the charging process, providing users with a more efficient and convenient charging experience, and significantly improving charging speed.

[0089] In one embodiment provided in this application, based on the above-described solution, optionally, increasing the available power of the charging interface includes:

[0090] In the charging system to which the charging interface belongs, a target component is identified, the target component including at least one of the following: a target charging interface having adjustable power in addition to the charging interface; and a power module having idle power in addition to an idle power module that supplies power to the charging interface.

[0091] Power allocation is performed on the target components to increase the available power of the charging interface.

[0092] In this embodiment, the available power of the charging interface can be increased by utilizing the adjustable power or idle power of the target component. Specifically, the target component can be another charging interface within the system with adjustable power, or another power module with idle power besides the power module that directly supplies power to the charging interface. By reasonably allocating power to these target components, the service capability of the specified charging interface can be dynamically enhanced, ensuring that it can meet higher power demands.

[0093] The method provided in this application not only improves the flexibility and resource utilization of the entire charging system, but also ensures the balance of power distribution among various charging interfaces, thereby optimizing the overall charging efficiency, improving the user experience, and providing an effective solution for power resource sharing in a multi-user environment.

[0094] In one embodiment provided in this application, based on the above-described scheme, optionally, after sending an indication message to the vehicle based on the current available power of the charging interface, the method further includes:

[0095] If the difference between the current available power of the charging interface and the required power of the vehicle connected to the charging interface is not less than the power threshold corresponding to the charging interface, and if it is detected that the difference between the current available power of the first interface and the required power of the vehicle connected to the first interface is less than the difference threshold, then the adjustable power of the charging interface will be allocated to the first interface; wherein, the first interface is any other charging interface in the charging system, and the adjustable power is the portion of the current available power of the charging interface that exceeds the required power of the vehicle connected to the charging interface.

[0096] In this embodiment, when the available power is detected to exceed the vehicle's required power and the difference is not lower than a set threshold, the system allocates the excess power to other interfaces in need, thereby optimizing resource allocation, improving charging flexibility and efficiency, ensuring system stability and safety, promoting the effective use of energy, and enhancing the user experience.

[0097] For example, if the current available power of charging interface 1 is 400kW, the power requirement of vehicle 1 connected to charging interface 1 is 250kW, the current available power of charging interface 2 is 200kW, the power requirement of vehicle 2 connected to charging interface 2 is 199kW, the difference threshold is 2kW, and the power threshold is 5kW. That is, the difference between the current available power of charging interface 1 and the power requirement of vehicle 1 connected to charging interface 1 is 150kW (400kW - 250kW), which is not less than the power threshold corresponding to the charging interface. Furthermore, the difference between the current available power of charging interface 2 and the power requirement of vehicle 2 connected to charging interface 2 is 1kW (200kW - 199kW), which is less than the difference threshold. In this case, the 150kW power of charging interface 1 can be allocated to charging interface 2 to increase the available power of charging interface 2. Then, an instruction message is sent to vehicle 2 based on the increased available power of charging interface 2, allowing vehicle 2 to redetermine its power requirement based on the increased available power of charging interface 2.

[0098] See Figure 3 This is another flowchart of a charging control method provided in this application. When the vehicle successfully connects to the charging interface and establishes communication, the charging controller determines and transmits the maximum output power (available power) of the charging gun to the vehicle based on the current usage of the power module and the upper limit of the charging interface's output power. Based on this information, the vehicle can adjust its required power, and during the charging process, the vehicle and the charging station periodically exchange data on the maximum output power and required power.

[0099] Specifically, the charging controller can poll the usage status of each power module, as well as the real-time charging power and required power of other charging interfaces. First, it determines the first power that can be provided by all the available idle power modules in the charging system, and takes this first power as the idle power P1. Then, it compares the idle power P1 with the output power upper limit value P2 of the charging interface. If P1 ≥ P2, it sets the maximum output power P of the charging interface to P2 and instructs the vehicle to start charging; if P1 < P2, it further queries the current available power P3 and required power P4 of other charging interfaces.

[0100] When the available power P3 of a certain other charging interface is greater than its required power P4, and the difference power (P3 - P4) ≥ the minimum adjustable power (adjustable power threshold) of this other charging interface, this difference power is allocated to the current charging interface, forming a new idle power P1' = P1 + (P3 - P4). If P1' ≥ P2, it sets the maximum output power P of the charging pile to P2; otherwise, it sets P = P1' and sends it to the vehicle to start charging.

[0101] During the charging process, the charging controller continuously monitors the difference between the required power P5 of the vehicle and the maximum output power P currently transmitted to the vehicle. If the difference between the two is less than the set threshold (for example, 2 kW), it triggers a new round of power resource search. That is, it queries whether there are idle power modules or adjustable power modules in other charging interfaces. If there is idle power, the idle power is allocated to the current charging interface through the power distribution module, and the maximum output power P' of this charging interface is updated as P' = the current maximum output power + the power of the allocated module. The updated maximum output power P' is sent to the vehicle. If the vehicle has a new required power P5', the charging power is adjusted according to the new required power P5'.

[0102] In this embodiment, the charging controller can continuously detect the difference between the current maximum output power and the vehicle required power. If the difference is lower than the set threshold again, it triggers a new round of power resource search to continuously explore available power resources, ensure meeting the maximum power requirement of the vehicle, and achieve the goal of fast charging.

[0103] Corresponding to Figure 1 the method, the embodiment of the present application also provides a charging control device for the specific implementation of the method in Figure 1 The structural schematic diagram is as shown in Figure 4 and includes:

[0106] The control unit 403 is used to control the charging interface to output electrical energy to the vehicle according to the power demand fed back by the vehicle.
