[0058] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0059] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0060] In combination with the accompanying drawings, the charging control method for a charging object, the charging control device for a charging object, the new energy system, the electronic device and the readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0061] The charging control method for a charging object may be applied to a terminal, and may be specifically executed by hardware or software in the terminal.

[0062] The terminal includes but is not limited to portable communication devices such as mobile phones or tablet computers. It should also be understood that in some embodiments, the terminal may not be a portable communication device, but a desktop computer.

[0063] The terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0064] The charging control method for a charging object provided in an embodiment of the present application may be executed by a new energy system, or by a charging control device for the charging object arranged on the new energy system, or by a server electrically connected (wired or wirelessly connected) to the new energy system, or by a user terminal communicatively connected to the new energy system, including but not limited to a mobile terminal and a non-mobile terminal.

[0065] like Figure 1 As shown, the charging control method of the charging object includes: step 110, step 120 and step 130.

[0066] The charging object is connected to the charging pile.

[0067] The charging object is an object that has a charging demand.

[0068] The charging objects can be electric vehicles, batteries, and storage batteries, etc.

[0069] Step 110: Obtain the operating status information reported by the charging pile;

[0070] In this step, the operating status information is information reported by the charging pile based on the charging status of the charging object connected thereto.

[0071] The operating status information includes: charging status or non-charging status.

[0072] The charging status is that the charging pile charges the charging object.

[0073] The non-charging state is that the charging pile is not charging the charging object.

[0074] In the actual execution process, the operation status information can be determined by the connection status between the charging pile and the charging object.

[0075] For example, when the charging pile is connected to the charging object through a charging gun, the operating status information can be determined as the charging status.

[0076] For another example, when the charging pile and the charging object are not connected via the charging gun, it can be determined that the operating status information is a non-charging state.

[0077] During the actual execution process, a communication connection between the cloud and the charging pile can be established to obtain the operating status information reported by the charging pile.

[0078] like Figure 2 As shown, in the actual implementation process, a network connection can be established between the cloud and the charging pile through a transmission control protocol long chain, and the operation status information of the charging pile can be obtained in a subscription-consumption manner. For example, when a user clicks to query the operation status of the charging pile, the operation status information reported by the charging pile can be output.

[0079] Step 120: When the operation status information is a charging status, obtain the actual charging power of the charging object;

[0080] In this step, the actual charging power is the charging power actually provided by the charging object to the charging object.

[0081] It is understandable that, when the operating status information is a charging status, the charging object may have a charging demand, and the charging pile needs to charge the charging object to increase the power of the charging object.

[0082] In the actual implementation process, the actual charging power of the charging object can be directly measured by a power meter, or the actual charging power can be calculated by measuring the voltage and current at both ends of the circuit where the charging object is located.

[0083] Of course, the actual charging power of the charging object may also be obtained in any other feasible manner.

[0084] Step 130: Determine the actual operating state of the charging pile based on the actual charging power;

[0085] In this step, the actual operating state is that the charging object starts charging and the charging pile supplies power to the charging object.

[0086] The actual operating status includes: charging or charging paused.

[0087] During charging, the charging pile can provide power to the charged object to increase the actual power of the charged object.

[0088] Charging pause means that the charging pile cannot provide power to the charging object, and the actual power of the charging object remains unchanged.

[0089] During the actual implementation process, the charging pile will be affected by the system scheduling and cannot provide power to the charging object. Although the charging pile is in a charging state, in fact, the charging pile does not charge the charging object, that is, charging is suspended.

[0090] In the actual implementation process, the actual charging power can be used to determine whether the charging pile provides power for the charging object, thereby determining the actual operating status of the charging pile.

[0091] For example, when the actual charging power is small or 0, the charging pile cannot output power to the charging object. At this time, it can be determined that the actual operating state of the charging pile is charging suspension.

[0092] For another example, when the actual charging power is not 0, the charging pile can output electric power to the charging object. At this time, it can be determined that the actual operating state of the charging pile is charging.

[0093] Step 140: Based on the actual operating status, control the charging pile to charge the charging object.

[0094] In this step, the charging action is an action performed to change or maintain the actual operating state of the charging pile.

[0095] During the actual implementation process, users can determine the charging action based on actual needs and predictions of subsequent changes in actual charging power.

[0096] For example, when the actual operating state is charging, the charging pile can be controlled to continue charging the charging object.

[0097] For example, when the actual operating state is charging, the charging pile can also be controlled to stop charging the charging object.

[0098] For another example, when the actual operating state is charging paused, and the user predicts that the actual charging power may remain at 0 for a long period of time, the charging pile can be controlled to stop charging the charging object.

[0099] During the research and development process, the inventors found that the charging pile lacked the ability to exchange information with the charging vehicle. In the related technology, the charging status of the electric vehicle is mainly determined by communication methods such as power line carrier, wireless radio frequency or Bluetooth. However, the above information interaction methods are affected by many factors, making the determined charging status low in accuracy and limited in applicable scenarios.

[0100] In addition, the inventors also found that in actual charging scenarios, the actual charging power may change due to the influence of the scheduling strategy, so that the charging pile cannot charge the charging object when it is in the charging state, and this situation cannot be known through the operating status information reported by the charging pile, affecting the user experience.

[0101] By acquiring the operating status information reported by the charging pile, the present application can understand the charging status of the charging pile in real time; when it is determined that the operating status information is the charging status, the actual charging power of the charging object is further acquired, and through the actual charging power, it is determined whether the charging pile is effectively charging the charging object at the time of collection, and the charging scenarios that are affected by the scheduling strategy and not included in the operating status information reported by the charging pile are effectively identified, and the influence of various factors on the charging process is considered to improve the accuracy of the determined actual operating status, enrich the applicable scenarios, reduce the unnecessary losses caused by long-term ineffective charging, and improve the user experience.

[0102] According to the charging control method for a charging object provided in an embodiment of the present application, by acquiring the operating status information reported by the charging pile, it is determined whether the charging pile is in a charging state. When it is determined that the charging pile is in a charging state, the actual operating state is further determined by the actual charging power, thereby improving the accuracy of the determined actual operating state, enriching the applicable scenarios, reducing unnecessary losses caused by long-term ineffective charging of the charging object, and improving the user experience.

[0103] In some embodiments, step 120 may further include:

[0104] When the operation status information is a charging state, obtaining the output power of the power supply object corresponding to the charging object;

[0105] Based on the output power of the power supply object, the actual charging power of the charging object is determined.

[0106] In this embodiment, the power supply object is a power generation system that provides power to the charging pile.

[0107] The power supply object may include one or more.

[0108] Output power refers to the amount of electricity provided by the power supply object to the power-consuming equipment per unit time.

[0109] Electrical equipment may include: charging piles, loads, and power grids, etc.

[0110] In the actual implementation process, the power supply object can be determined according to the actual situation of the power generation system connected to the charging pile.

[0111] In actual implementation, the output power of the power supply object can be directly measured by a power meter, or the output power can be calculated by measuring the voltage and current at both ends of the circuit where the power supply object is located.

[0112] Of course, the output power of the power supply object can also be obtained through any other feasible method.

[0113] When the power supply object provides power to the charging pile, the charging pile can charge the charging object. When the power supply object does not provide power to the charging pile, the charging pile cannot charge the charging object.

[0114] When the power supply object provides a large amount of electricity to the charging pile, the actual charging power will also be large.

[0115] When the amount of electricity provided by the power supply object to the charging pile is small, the actual charging power will also be small.

[0116] For example, when the output power of the power supply object is 0, the power supply object does not provide power to the charging pile, the charging pile cannot charge the charging object, and the actual charging power will also be 0.

[0117] According to the charging control method for a charging object provided in an embodiment of the present application, by determining the output power of a power supply object that provides electricity to the charging object, it is possible to determine the actual charging power of the charging object based on the actual scheduling situation of the power supply object, thereby improving the accuracy of the determined actual charging power.

[0118] In some embodiments, obtaining the output power of the power supply object corresponding to the charging object includes:

[0119] When the power supply object includes a photovoltaic system, obtaining the power generation power of the photovoltaic system as the output power;

[0120] When the power supply object includes an energy storage system, obtaining the discharge power of the energy storage system as the output power;

[0121] When the power supply object includes a photovoltaic system and an energy storage system, the sum of the power generation power of the photovoltaic system and the discharge power of the energy storage system is obtained as the output power.

[0122] In this embodiment, the power generated is the rate at which the photovoltaic system converts solar radiation into electrical energy.

[0123] Discharge power is the ability of the energy storage system to output electricity per unit time.

[0124] In the actual implementation process, the output power of the power supply object can be determined based on the actual setting situation of the power supply object.

[0125] When the power supply object includes a photovoltaic system, electricity is provided by the photovoltaic system, and the output power of the power supply object is the power generation power of the photovoltaic system.

[0126] When the power supply object includes an energy storage system, the power is provided by the energy storage system, and the output power of the power supply object is the power generation power of the energy storage system.

[0127] When the power supply object includes a photovoltaic system and an energy storage system, electricity is provided by the photovoltaic system and the energy storage system together, and the output power of the power supply object is the sum of the generated power and the discharged power.

[0128] According to the charging control method for a charging object provided in an embodiment of the present application, a method for calculating the output power of the power supply object is determined by determining the actual settings of the power supply object. The output power of the power supply object may be different for different power supply objects. Based on the actual settings of the power supply object, the output power of the power supply object can be flexibly obtained, which has a wide range of applicable scenarios.

[0129] In some embodiments, determining the actual charging power of the charging object based on the output power of the power supply object includes:

[0130] When the power supply object corresponds to an electric device other than a charging pile, the actual charging power is determined based on the difference between the output power of the power supply object and the power consumption of the electric device.

[0131] In this embodiment, the electric device includes one or more of a power grid and a load.

[0132] The electrical equipment may include one or more loads.

[0133] The power consumption is the power provided by the power supply object consumed by the electrical equipment.

[0134] When the electrical equipment includes a power grid, the consumed power is the power consumed by the power grid.

[0135] When the electric device includes one or more loads, the consumed power is the power consumed by the one or more loads together.

[0136] In the case where the power-consuming device includes a power grid and one or more loads, the consumed power is the power consumed by the power grid and all the loads connected to the power supply object.

[0137] In the actual implementation process, the power consumed by the power grid and the power consumed by one or more loads can be directly measured by a power meter, or the power consumed by the power grid can be calculated by measuring the voltage and current at both ends of the circuit where the power grid is located, and the power consumed by the load can be calculated by measuring the voltage and current at both ends of the circuit where the load is located.

[0138] In the case where the electric device includes a power grid and one or more loads, the power consumed by the power grid and the power consumed by the one or more loads are added together to obtain the power consumed by the electric device.

[0139] Of course, the power consumption may also be obtained in any other feasible manner.

[0140] In the actual implementation process, after determining the output power of the power supply object and the power consumption of the power-consuming equipment, a difference calculation can be performed to obtain the actual charging power.

[0141] The actual charging power can be calculated based on the following formula:

[0142] Actual charging power = output power - power consumption.

[0143] Power consumption = power consumed by the load + power consumed by the grid.

[0144] In some embodiments, when the power supply target has no power-consuming equipment other than the charging pile, the output power of the power supply system is the actual charging power.

[0145] According to the charging control method for a charging object provided in an embodiment of the present application, by determining that the power supply object corresponds to an electrical device other than a charging pile that consumes the power provided by the power supply object, the actual charging power is accurately calculated based on the difference between the output power of the power supply object and the power consumption of the electrical device, thereby improving the accuracy of the determined actual charging power.

[0146] In some embodiments, step 130 may further include:

[0147] Based on the actual charging power and the target power threshold, the actual operating state is determined.

[0148] In this embodiment, the target power threshold is the starting charging power of the charging object.

[0149] The target power threshold can be set according to the charging object. For example, the starting charging power of electric vehicles and battery vehicles is different, and the set target power threshold will also be different.

[0150] The specific value of the target power threshold may also be user-defined or determined based on actual conditions, and this application does not limit this.

[0151] In the actual execution process, the correlation between the actual charging power and the target power threshold can be compared to determine the actual operating status of the charging pile.

[0152] According to the charging control method for a charging object provided in an embodiment of the present application, the actual operating state is determined by the correlation between the actual charging power and the target power threshold. The judgment method is simple and easy to implement. In addition, the target power threshold can be flexibly adjusted based on actual needs. It is suitable for different scenarios and has strong flexibility.

[0153] In some embodiments, determining the actual operating state based on the actual charging power and the target power threshold may further include:

[0154] When the actual charging power is less than the target power threshold, determining that the actual operating state is charging suspension;

[0155] When the actual charging power is not less than the target power threshold, it is determined that the actual operating state is charging.

[0156] In this embodiment, when the actual charging power is less than the target power threshold, it indicates that the actual charging power has not reached the starting charging power of the charging object. Although the charging pile is in a charging state, it does not provide power to the charging object. At this time, the actual operating state is charging suspension.

[0157] When the actual charging power is not less than the target power threshold, it indicates that the actual charging power reaches the starting charging power of the charging object, and the charging pile can charge the charging object normally. At this time, the actual operating state is charging.

[0158] According to the charging control method for a charging object provided in an embodiment of the present application, by comparing the size relationship between the actual charging power and the target power threshold, the actual operating state is effectively judged. When the actual charging power is less than the target power threshold, the actual operating state is determined to be charging paused. When the actual charging power is not less than the target power threshold, the actual operating state is determined to be charging. Different target power thresholds are determined according to different charging objects to more accurately judge the actual operating state. The judgment method is flexible, the application range is wide, the judgment logic is simple, and it is easy to operate.

[0159] like Figure 2 As shown, in some embodiments, step 130 may also include:

[0160] The actual charging power is input into the target recognition model to obtain the actual operating state output by the target recognition model;

[0161] The target recognition model is trained using historical charging power as sample data and historical operating status as sample labels.

[0162] In this embodiment, the target recognition model is a model for recognizing the actual operating status of the charging pile.

[0163] The target recognition model can be a neural network model or a machine learning model.

[0164] The following takes the target recognition model as a long short-term memory network model as an example for explanation.

[0165] The LSTM network model is used to address the gradient vanishing and gradient exploding problems encountered by standard recurrent neural networks when processing long sequence data.

[0166] The long short-term memory network model controls the storage, update and output of information by introducing forget gate, input gate and output gate.

[0167] The forget gate controls the LSTM cell's decision on how much information to "forget" from the current cell state.

[0168] The forget gate determines the “forgotten” information based on the following formula:

[0169] ft=σ(Wf·[ht-1,xt]+bf);

[0170] Among them, ft is the output of the forget gate, ft is between 0 and 1, 0 means complete forgetting, and 1 means complete retention; Wf is the weight matrix of the forget gate; [ht-1, xt] is the concatenation vector of the hidden state at the previous moment and the current input; bf is the bias vector of the forget gate; σ is the sigmoid activation function, which maps the result of the linear transformation to between (0,1).

[0171] The input gate controls how much new information the LSTM unit decides to add to the current state.

[0172] The input gate adds new information based on the following formula:

[0173] It = σ(Wi · [ht-1, xt] + bi);

[0174] Among them, It is the output of the input gate, which controls the introduction of new information; Wi is the weight matrix of the input gate; [ht-1,xt] is the concatenation vector of the hidden state at the previous moment and the current input; bi is the bias vector of the input gate.

[0175] The LSTM model generates a new candidate state from the current input and the hidden state at the previous moment based on the following formula:

[0176] Ct`=tanh(WC·[ht-1,xt]+bC);

[0177] Among them, Ct` is the candidate state, which can be generated by the tanh activation function; WC is the weight matrix for generating the candidate state; [ht-1, xt] is the concatenation vector of the hidden state at the previous moment and the current input; bC is the bias vector for generating the candidate state; tanh is the hyperbolic tangent activation function, which maps the value to between (-1, 1).

[0178] The LSTM model updates the cell state based on the following formula, using the cell state and candidate state at the previous moment under the control of the forget gate and input gate:

[0179] Ct=ft⊙Ct-1+it⊙Ct`;

[0180] Among them, Ct is the unit state at the current moment; ⊙ represents the bit-by-bit multiplication of elements (Hadamard product); ft⊙Ct-1 is the retained part of the state at the previous moment after being controlled by the forget gate; it⊙Ct` is the added part of the new candidate state after being controlled by the input gate.

[0181] The output gate determines which parts of the current unit state will be output as the hidden state at the current moment.

[0182] The output gate determines the hidden state of the current moment output in the current moment unit state based on the following formula:

[0183] Ot=σ(Wo·[ht-1,xt]+bo);

[0184] Among them, Ot is the output of the output gate, which determines the proportion of output information; Wo is the weight matrix of the output gate; [ht-1,xt] is the concatenation vector of the hidden state at the previous moment and the current input; bo is the bias vector of the output gate.

[0185] The LSTM model outputs the current hidden state based on the following formula:

[0186] Ht=ot⊙tanh(Ct);

[0187] Among them, Ht is the hidden state at the current moment, and tanh(Ct) is the nonlinear transformation of the current unit state.

[0188] During the actual execution process, the historical operation status information reported by multiple charging piles can be collected, and the historical charging power of the charging object and the historical operation status corresponding to the historical charging power can be filtered out from the historical operation status information when the historical operation status information is the charging status.

[0189] Continue to refer Figure 2 , perform data preprocessing operations such as data cleaning, feature extraction, and data standardization on the acquired historical charging power.

[0190] In the actual implementation process, the historical charging power after data preprocessing can be divided, and part of the historical charging power after data preprocessing is used as a training set, and the remaining historical charging power except part of the historical charging power is used as a verification set.

[0191] Part of the historical charging power is used as sample data, and the historical operating status corresponding to the part of the historical charging power is used as sample labels to train the Long Short-Term Memory (LSTM) network model.

[0192] The trained LSTM model is verified by the remaining historical charging power to evaluate the performance of the LSTM model. Based on the evaluation results, the parameters of the LSTM model are adjusted, and the LSTM model is continuously optimized to obtain the optimal LSTM model.

[0193] After obtaining the optimal LSTM model, the LSTM model is deployed to process the actual charging power of the acquired charging object, perform state recognition, and obtain the actual operating state of the charging pile.

[0194] According to the charging control method for a charging object provided in an embodiment of the present application, the actual operating status of the charging pile can be obtained by inputting the actual charging power into the target recognition model. There is no need to manually process the acquired data, which improves the efficiency of data processing, reduces the errors caused by manual processing of data, and improves the accuracy of the actual operating status obtained.

[0195] Continue to refer Figure 2 In some embodiments, after step 130, the method further includes:

[0196] Based on the actual operating status, charging status prompt information is output.

[0197] In this embodiment, the charging status prompt information is information that prompts the user of the charging status of the charging pile.

[0198] The charging status prompt information may include: actual charging status, charging time, remaining charging time, current power level and other information.

[0199] After the actual operating status is obtained, charging status prompt information can be output to the user.

[0200] For example, the charging status prompt information may be: the actual charging status of charging pile A is charging paused, the charging time is A, and other information.

[0201] For another example, the charging status prompt information may be: the actual charging status of charging pile No. B is charging, and the current charging power is 70%.

[0202] Continue to refer Figure 2 ,The cloud can establish a WebSocket connection with the application and push charging status prompt information to the user.

[0203] Continue to refer Figure 2 In some embodiments, when the operating status information reported by the charging pile is a non-charging status, charging status prompt information may also be output to the user.

[0204] In this embodiment, the charging status prompt information may be that the charging pile is not charging.

[0205] In the subsequent use process, the user can send a charging start instruction to the charging pile based on actual usage needs to control the charging pile to charge the charging object.

[0206] According to the charging control method for a charging object provided in an embodiment of the present application, by outputting charging status prompt information, the user can timely understand the charging status of the charging object. The user can reasonably arrange the time based on the output charging status prompt information to avoid long waiting times during the charging process, thereby improving the user experience.

[0207] In some embodiments, step 140 may further include:

[0208] When the actual operating state is charging pause, the charging pile is controlled to stop charging the charging object;

[0209] or,

[0210] The charging pile is controlled to maintain the current operating state, so that the charging pile continues to charge the charging object when the actual charging power is not less than the target power threshold.

[0211] In this embodiment, when the actual operating state is charging pause, the charging pile receives an instruction to charge the charging object, but the charging pile does not charge the charging object.

[0212] At this time, if the user does not want to continue waiting, he can send a stop charging instruction to the charging pile to control the charging pile to stop charging the charging object.

[0213] After the user issues a stop charging instruction, the user can be redirected to the settlement page to output charging record information and related fee information to the user.

[0214] If the user can continue to wait, the charging pile can maintain the current operating state. In the subsequent operation of the charging pile, if the actual charging power of the charging object is greater than or equal to the target power threshold, the charging pile will continue to charge the charging object.

[0215] When the actual operating state is charging, the charging pile can be controlled to stop charging the charging object, or the charging pile can be controlled to maintain the current operating state and continue charging the charging object.

[0216] According to the charging control method for a charging object provided in an embodiment of the present application, through the actual situation of the actual operating state, the user can control the operating state of the charging pile based on actual usage needs, control the charging pile to stop charging the charging object, or continue to keep the charging pile in a charging state, flexibly control the charging pile, and improve the user experience.

[0224] The fourth processing module 340 is used to control the charging action of the charging pile to the charging object based on the actual operating status.

When it is determined that the charging pile is in a charging state, the actual operating state is further determined through the actual charging power, thereby improving the accuracy of the determined actual operating state, enriching the applicable scenarios, reducing unnecessary losses caused by long-term ineffective charging of the charging object, and improving the user experience.

[0229] In some embodiments, the second processing module 320 may also be used to:

[0230] When the power supply object corresponds to an electric device other than a charging pile, the actual charging power is determined based on the difference between the output power of the power supply object and the power consumption of the electric device.
