Description

Technical Field

[0001] The present application belongs to the field of communication technology and relates to an automobile charging communication technology, and in particular to a charging communication management system and a charging communication management method. Background Art

[0002] EVCC (Electric Vehicle Communication Controller) is the communication hub between electric vehicles and charging piles. It is used to convert signals from BMS (Battery Management System) into signals that can be received by charging piles, and control the charging process and data exchange.

[0003] Since the car needs to be equipped with multiple charging ports, in the existing technology, the BMS often needs to communicate with multiple EVCCs, or needs to change the configuration of the charging pile, add a communication coordination mechanism and a power distribution mechanism between different charging guns to adapt the communication between multiple charging ports and a single BMS. However, the former has a complex communication procedure, high control complexity, and a huge amount of data generated in the communication, which reduces the computing efficiency of the communication system and consumes a lot of energy. The latter requires the modification of the charging pile, which is costly and makes the car's charging system less adaptable.

[0004] Therefore, how to simply and efficiently implement charging communication management of multi-port charging is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] The purpose of the present application is to provide a charging communication management system and a charging communication management method, which are used to solve the problem that the charging communication of multiple charging ports in the prior art requires the BMS to communicate with multiple EVCCs at the same time, which makes the communication procedure complicated and the control complexity large, thereby causing the communication system to have low computing efficiency and high energy consumption, or the charging piles need to be modified, making the charging system of the car less adaptable and costly.

[0006] In a first aspect, the present application provides a charging communication management system, including a battery manager and a plurality of communication controllers connected to the battery manager through a channel, wherein all the communication controllers are in a message monitoring state;

[0007] Any one of the communication controllers, when receiving a charging request initiated by a corresponding charging pile and failing to monitor the charging communication data in the channel, establishes a communication channel with the battery manager as a main communication controller, receives the main charging pile parameters fed back by the corresponding charging pile and generates main charging pile parameter information, sends the main charging pile parameter information to the battery manager based on the charging request through the communication channel, receives the battery charging parameters fed back by the battery manager, monitors the slave charging pile parameter information in the channel, and organizes all the monitored slave charging pile parameter information and sends them to the battery manager;

[0008] Any one of the communication controllers, when receiving a charging request initiated by a corresponding charging pile and monitoring the charging communication data in the channel, sends a parameter acquisition signal generated based on the monitored battery charging parameters to the corresponding charging pile as a slave communication controller, receives slave charging pile parameters fed back by the corresponding charging pile, generates slave charging pile parameter information based on the slave charging pile parameters and broadcasts it;

[0009] The battery manager is used to send battery charging parameters to the main communication controller, receive the main charging pile parameter information and all the slave charging pile parameter information, generate request parameters based on the battery charging parameters, the main charging pile parameter information and all the slave charging pile parameter information, and send the request parameters to the main communication controller.

[0010] In this application, since the battery manager only establishes a communication channel with the main communication controller for communication, while ensuring normal data interaction during the charging process, it avoids communication congestion caused by multiple communication channels, simplifies the communication procedure, improves the communication efficiency during the charging process, reduces system energy consumption, and thus achieves a better charging effect.

[0011] In one embodiment of the present application, the master communication controller is further configured to generate charging parameter allocation information based on the request parameter, the master charging pile parameter and all the slave charging pile parameters, enter the charging cycle phase based on the charging parameter allocation information, and broadcast the charging parameter allocation information;

[0012] The slave communication controller is further configured to enter a charging cycle phase based on the charging parameter allocation information.

[0013] In one embodiment of the present application, the request parameters include a requested current; the main communication controller obtains the corresponding number of all the charging piles and the maximum output current based on the main charging pile parameters and all the slave charging pile parameters, and uses the ratio of the requested current to the number of all the charging piles as the average current, and determines whether the average current is less than all the maximum output currents. If so, the charging parameter allocation information is generated based on the average current; otherwise, the charging parameter allocation information is generated based on the maximum output current.

[0014] In one embodiment of the present application, the master communication controller is further used to broadcast the master charging status of its charging cycle stage in real time;

[0015] The slave communication controller is also used for, when the master communication controller is in the charging cycle stage, after receiving a charging request initiated by the corresponding charging pile, sending a parameter acquisition signal generated based on the monitored battery charging parameters to the corresponding charging pile, receiving the slave charging pile parameters fed back by the corresponding charging pile, generating slave charging pile parameter information based on the slave charging pile parameters and broadcasting it, and entering the charging cycle stage based on the latest received charging parameter allocation information and the latest monitored main charging state; wherein the latest charging parameter allocation information is obtained by the master communication controller generating the charging parameter allocation information based on the latest request parameters, the master charging pile parameters and all the current slave charging pile parameters; the latest request parameters are obtained by the battery manager generating the request parameters based on the battery charging parameters, the master charging pile parameter information and all the current slave charging pile parameter information.

[0016] In one embodiment of the present application, the master communication controller is further configured to, when receiving a stop charging request initiated by the corresponding charging pile, select a backup communication controller from all the slave communication controllers according to a preset screening basis, send a takeover signal to the backup communication controller, and disconnect the communication channel with the battery manager;

[0017] The standby communication controller is used to establish a communication channel with the battery manager based on the takeover signal to serve as a new main communication controller, and its corresponding charging pile parameters are new main charging pile parameters.

[0018] In one embodiment of the present application, the slave charging pile parameter information includes the output power of the corresponding charging pile; screening out a backup communication controller from all the slave communication controllers according to a preset screening criterion includes: based on all the slave charging pile parameter information, screening the slave communication controller corresponding to the charging pile with the largest output power as the backup communication controller.

[0019] In one embodiment of the present application, the battery manager is further used to send a request to end charging to the main communication controller through the communication channel;

[0020] The master communication controller is further used to disconnect the communication channel with the battery manager based on the charging end request, and all the slave communication controllers listen to the charging end request, so that each of the communication controllers is disconnected from the corresponding charging pile.

[0021] In one embodiment of the present application, when the main communication controller meets the monitoring condition, all the monitored slave charging pile parameters are sent to the battery manager; the monitoring condition is that the charging request initiated by the corresponding charging pile has been received for a preset time threshold or a preset number of slave charging pile parameters have been received.

[0022] In a second aspect, the present application provides a charging communication management method, including:

[0023] All communication controllers in the charging communication management system are in a message monitoring state. When any of the communication controllers receives a charging request initiated by a corresponding charging pile and fails to monitor the charging communication data in the channel, it is used as a main communication controller to establish a communication channel with the battery manager, and receives the main charging pile parameters fed back by the corresponding charging pile and generates main charging pile parameter information, and sends the main charging pile parameter information to the battery manager through the communication channel based on the charging request;

[0024] The battery manager sends battery charging parameters to the main communication controller and receives main charging pile parameters; the main communication controller receives the battery charging parameters fed back by the battery manager;

[0026] The main communication controller sends all monitored slave charging pile parameters to the battery manager;

[0027] The battery manager receives all the slave charging pile parameter information, generates request parameters based on the battery charging parameters, the master charging pile parameter information and all the slave charging pile parameter information, and sends the request parameters to the master communication controller.

[0028] In the present application, based on the aforementioned charging communication management system, a charging communication management method is executed. While realizing the normal charging process, by establishing only one communication channel between the main communication controller and the battery manager, the communication process is simplified, and congestion caused by multiple communication channels is avoided, which is beneficial to improving the communication efficiency during the charging process.

[0029] In one embodiment of the present application, when the main communication controller receives a request to stop charging initiated by the corresponding charging pile, the main communication controller selects a backup communication controller from all the slave communication controllers according to a preset screening basis, and sends a takeover signal to the backup communication controller;

[0030] The standby communication controller establishes a communication channel with the battery manager based on the takeover signal to serve as a new main communication controller, and its corresponding charging pile parameters are new main charging pile parameters;

[0031] The main communication controller disconnects the communication channel with the battery manager.

[0038] 102 Communication Controller

[0039] 103 charging piles DETAILED DESCRIPTION

[0040] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0041] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0042] The following embodiments of the present application provide a charging communication management system and a charging communication management method to achieve efficient communication of the charging system. By establishing a communication channel only between the battery manager and a single communication controller, the problem in the prior art, including communication between the battery manager and multiple communication controllers, is solved, in which the communication procedure is complicated due to the existence of multiple communication channels at the same time, thereby affecting the computing efficiency and energy consumption. This is conducive to achieving efficient communication during charging.

[0043] The following embodiments of the present application provide a charging communication management system and a charging communication management method, including but not limited to the communication process applied to charging of electric vehicles. The following description will be given using the charging communication management system of an electric vehicle as an example.

[0044] like Figure 1 As shown, the charging communication management system 100 provided in this embodiment includes a battery manager 101 and multiple communication controllers 102 connected to the battery manager 101 through channels, and all communication controllers 102 are in a message monitoring state. Among them, the battery manager 101 is used to monitor and manage the battery status, and send battery charging parameters based on this. The communication controller is connected to an external charging pile 103 so that the charging pile 103 charges the battery system according to the preset charging parameters. It should be noted that the channel connecting the battery manager 101 and the multiple communication controllers 102 refers to a data transmission channel for realizing data interaction between the battery manager 101 and the multiple communication controllers 102. Specifically, the channel can be a wired channel, such as connecting the battery manager 101 and the multiple communication controllers 102 through a bus, or it can also be a wireless channel, such as realizing data interaction between the battery manager 101 and the multiple communication controllers 102 through WIFI.

[0045] Further, all communication controllers 102 are continuously in a message monitoring state, and after receiving a charging request from the corresponding charging pile 103, they communicate with the corresponding charging pile 103. It should be noted that only one communication controller 102 among all communication controllers 102 is a main communication controller, and establishes a communication channel with the battery manager 101. Among them, all data in the communication channel can be monitored by all communication controllers 102 in the message monitoring state. Specifically, when any communication controller 102 receives a charging request initiated by the corresponding charging pile 103 and does not monitor the charging communication data in the channel, it establishes a communication channel with the battery manager 101 as a main communication controller to realize the communication of the charging communication management system 100. Among them, the charging communication data is the communication data in the channel. When the battery manager 101 is in an idle state, that is, when the battery is not in a charging state, there is no charging communication data in the channel; when the battery manager 101 is in a charging state, that is, when the battery is in a charging state, there is charging communication data in the channel. Specifically, the charging communication data includes but is not limited to communication data such as charging pile parameters and battery charging parameters.

[0046] In the charging communication management system 100 provided in this embodiment, the main communication controller establishes a communication channel with the battery manager 101 for communication, and other communication controllers 102 do not communicate with the battery manager 101, that is, there is only one communication channel in the charging communication management system 100, so as to avoid communication congestion caused by multiple communication channels, simplify the communication procedures, improve the communication efficiency during the charging process, reduce the system energy consumption, and thus achieve a better charging effect. It should be noted that the main communication controller described in this embodiment can be any communication controller 102 in the charging communication management system 100, as long as it receives the charging request initiated by the corresponding charging pile 103 and does not monitor the charging communication data in the channel, it can be used as the main communication controller, and it has nothing to do with the specific position of the communication controller 102 in the charging communication management system 100 or the connection method and interface type with the external charging pile, and this embodiment does not make specific restrictions here.

[0047] The master communication controller receives the master charging pile parameters fed back by the corresponding charging pile 103 to generate master charging pile parameter information, sends the master charging pile parameter information to the battery manager 101 based on the charging request through the communication channel, and receives the battery charging parameters fed back by the battery manager 101; the battery manager 101 sends the battery charging parameters to the master communication controller, and receives the master charging pile parameter information and all the slave charging pile parameter information. Among them, the master charging pile parameters represent the maximum output capacity of the charging pile 103 corresponding to the master communication controller, and the battery charging parameters represent the charging requirements of the battery.

[0048] Based on this, the battery manager 101 obtains the output capacity of the charging pile 103 corresponding to the main communication controller, so that the battery manager 101 can formulate the most appropriate charging plan based on the actual output capacity of the connected charging pile 103 to achieve the best charging effect.

[0049] The battery manager 101 sends the battery charging parameters to the master communication controller through the communication channel, so that the slave communication controllers in the charging communication management system 100 that are in the listening state can listen to the battery charging parameters, thereby realizing that the charging pile 103 corresponding to the slave communication controller can charge normally when the slave communication controller does not communicate with the battery manager 101. The slave communication controller is the communication controller 102 in the charging communication management system 100 that can communicate with the corresponding charging pile 103 but does not communicate with the battery manager 101.

[0050] Specifically, any communication controller 102, when receiving a charging request initiated by the corresponding charging pile 103 and monitoring the charging communication data in the channel, acts as a slave communication controller. The slave communication controller generates a parameter acquisition signal based on the monitored battery charging parameters and sends it to the corresponding charging pile 103, and the corresponding charging pile 103 feeds back the slave charging pile parameters to the slave communication controller. The slave charging pile parameters represent the maximum output capacity of the charging pile.

[0051] Furthermore, the slave communication controller also generates slave charging pile parameter information based on the slave charging pile parameters and broadcasts it. The master communication controller will monitor the slave charging pile parameter information and send it to the battery manager 101, so that the battery manager 101 can obtain the actual output capacity of all charging piles 103 connected to the charging communication management system 100, and then formulate the most appropriate charging plan to achieve the best charging effect.

[0052] It should be noted that the charging pile parameters may also include the current output power fed back in real time by the corresponding charging pile 103 , so as to characterize the current power output and charging state of the corresponding charging pile 103 .

[0053] Specifically, the battery manager 101 generates request parameters based on the battery charging parameters, the main charging pile parameter information and all the slave charging pile parameter information, and sends the request parameters to the main communication controller. The request parameters are the power input requirements required for battery charging, including but not limited to the requested current, requested voltage and requested power. The battery manager 101 sends the request parameters to the main communication controller to request corresponding power output from all the charging piles 103 connected to the charging communication management system 100, so as to charge the battery.

[0054] In this embodiment, all communication controllers 102 are in a message monitoring state to normally receive the battery charging parameters of the battery manager 101, so as to communicate normally with the charging pile, and broadcast the charging pile parameter information of the corresponding charging pile 103, so that the main communication controller can obtain all the charging pile parameter information, and send it to the battery manager 101 through the communication channel between the main communication controller and the battery manager 101, so that the battery manager 101 can normally obtain the actual output capacity of all connected charging piles, and formulate the most suitable charging plan based on this. Based on this, the charging communication management system 100 provided in this embodiment, by only establishing a communication channel between the main communication controller and the battery manager 101, simplifies the communication procedure of the charging communication management system 100 while realizing the normal charging process, improves the operation efficiency of the charging communication management system 100, and achieves a better charging effect.

[0055] It should be noted that, in this embodiment, the main communication controller is also used to send all the slave charging pile parameter information monitored to the battery manager 101. Specifically, when the main communication controller meets the monitoring condition, all the slave charging pile parameters monitored are sent to the battery manager 101. Among them, the preset monitoring condition is that the charging request initiated by the corresponding charging pile has been received for a preset time threshold, that is, the main communication controller completes a monitoring according to the preset time threshold, sends all the slave charging pile parameter information monitored to the battery manager 101 at the time point of completing this monitoring, and restarts the next monitoring; or the preset number of slave charging pile parameters have been received, that is, the main communication controller monitors the preset number of slave charging pile parameter information each time, and sends it to the battery manager 101. It should be noted that the main charging pile parameter information can be packaged with other slave charging pile parameter information as the same data packet and sent to the battery manager 101, or it can be sent to the battery manager 101 separately. Specifically, as long as all the charging pile parameter information can be sent to the battery manager 101, this embodiment does not make specific restrictions here.

[0056] Furthermore, after receiving the request parameters from the battery manager 101, the master communication controller generates charging parameter allocation information based on the request parameters, the master charging pile parameters and all slave charging pile parameters, and broadcasts the charging parameter allocation information so that all slave communication controllers obtain their corresponding charging parameters and communicate with the corresponding charging piles 103 to realize charging of the battery.

[0057] The master communication controller enters the charging cycle phase based on the charging parameter allocation information, and the slave communication controller enters the charging cycle phase based on the charging parameter allocation information.

[0058] Specifically, the master communication controller obtains the corresponding quantity and maximum output current of all charging piles based on the master charging pile parameters and all slave charging pile parameters, and allocates the request parameters based on this to generate charging parameter allocation information.

[0059] Exemplarily, the request parameters include the requested current, and the ratio of the requested current to the number of all charging piles 103 is used as the shared current. It is determined whether the shared current is less than the maximum output current of all charging piles 103. If so, the main communication controller generates charging parameter allocation information based on the shared current; otherwise, the main communication controller generates charging parameter allocation information based on the maximum output current.

[0060] Based on this, the charging communication management system 100 provided in this embodiment realizes the allocation of charging parameters to each charging pile 103 by establishing a communication channel only between the main communication controller and the battery manager 101. Each communication controller 102 communicates with the corresponding charging pile 103 based on the charging parameter allocation information to ensure normal charging of the battery.

[0061] It should be noted that, generally speaking, the time when the charging pile 103 corresponding to the slave communication controller connects to the charging communication management system 100 is later than the charging pile 103 of the master communication controller. At this time, the charging pile 103 corresponding to the master communication controller may have entered the charging cycle stage, that is, the battery voltage has been gradually rising. If the voltage output by the charging pile 103 corresponding to the slave communication controller after connecting to the charging communication management system 100 is greatly different from the current voltage of the battery, there may be a voltage difference between the charging pile 103 corresponding to the slave communication controller and the battery, thereby generating an impact current and causing a safety hazard. Based on this, the slave communication controller obtains the charging status of the master communication controller, and communicates with the corresponding charging pile 103 based on this, so that the corresponding charging pile 103 outputs a suitable voltage to avoid the voltage difference between the charging pile 103 corresponding to the slave communication controller and the battery, which causes a safety hazard.

[0062] Specifically, the master communication controller is also used to broadcast the master charging status of its charging cycle stage in real time, so that the slave communication controller can monitor and obtain the charging status of the master communication controller; after the slave communication controller is connected and communicated with the corresponding charging pile 103, it enters the charging cycle stage based on the latest received charging parameter allocation information and the latest monitored master charging status. The latest charging parameter allocation information is obtained by the master communication controller based on the latest request parameters, master charging pile parameters and all current slave charging pile parameters to generate charging parameter allocation information; the latest request parameters are obtained by the battery manager 101 based on the battery charging parameters, master charging pile parameter information and all current slave charging pile parameter information to generate request parameters. The master charging status includes the charging voltage of the charging pile 103 corresponding to the master communication controller, and the slave communication controller enters the charging cycle stage based on the master charging status to avoid the voltage difference between the charging pile 103 corresponding to the slave communication controller and the battery. Exemplarily, the slave communication controller sends the charging voltage corresponding to the master communication controller as a charging parameter to the corresponding charging pile 103 as the charging voltage of the charging pile 103 corresponding to the slave communication controller.

[0063] Further, when the charging pile 103 stops charging, a stop charging request is sent to the corresponding communication controller 102 to disconnect the communication and charging with the charging communication management system 100. Wherein, when the charging pile 103 that sends the stop charging request is the charging pile 103 corresponding to the main communication controller, the main communication controller selects the backup communication controller from all the slave communication controllers according to the preset screening basis, sends a takeover signal to the backup communication controller to ensure that the communication between the communication controller 102 and the battery manager 101 can continue, and then disconnects the communication channel with the battery manager 101. Wherein, the backup communication controller establishes a communication channel with the battery manager 101 based on the takeover signal to serve as a new main communication controller, and its corresponding charging pile parameters are the new main charging pile parameters.

[0064] Exemplarily, the standby communication controller is the one whose corresponding charging pile 103 has the largest output power among all the slave communication controllers. Specifically, the slave charging pile parameter information includes the output power of the corresponding charging pile 103. The master communication controller selects the slave communication controller corresponding to the charging pile 103 with the largest output power based on all the slave charging pile parameters monitored, and uses it as the standby communication controller.

[0065] Of course, the standby communication controller may also be other screening criteria, for example, the standby communication controller is the one with the largest identity among all slave communication controllers. Specifically, the slave charging pile parameter information includes the identity of the corresponding slave communication controller. The master communication controller screens the slave communication controller with the largest identity based on all the slave charging pile parameters monitored to use it as the standby communication controller, or the slave communication controller with the smallest identity may be screened to use it as the standby communication controller. Specifically, as long as the standby communication controller can be screened out from all slave communication controllers, this embodiment does not make any specific restrictions here.

[0066] It should be noted that when the charging pile 103 that sends the stop charging request is the charging pile 103 corresponding to any slave communication controller, the slave communication controller directly disconnects from the charging pile 103. Further, the slave communication controller can continue to be in the message monitoring state or stop monitoring. Preferably, the slave communication controller continues to be in the message monitoring state. When another charging pile 103 is connected to the slave communication controller, the slave communication controller receives the charging request and communicates with the charging pile based on the monitored battery charging parameters, charging parameter allocation information and other charging communication data.

[0067] Furthermore, when the battery is fully charged, all charging posts 103 stop charging, and at this time, the battery manager 101 sends a request to end charging, so that all communication controllers are disconnected from their corresponding charging posts. Specifically, the battery manager 101 sends a request to end charging to the main communication controller through the communication channel; each communication controller 102 can monitor the request to end charging in the communication channel and disconnect from the corresponding charging post 103 based on it.

[0068] Based on this, the charging communication management system 100 provided in this embodiment completes the normal battery charging process. At the same time, since the battery manager 101 only communicates with the main communication controller through the communication channel, the communication process is simple, which makes the charging communication management system 100 more efficient and consumes less energy, thereby achieving a better charging effect.

[0069] In order to facilitate those skilled in the art to further understand the charging communication management system 100 provided in this embodiment, this embodiment provides a charging communication management method for communicating based on the aforementioned charging communication management system 100.

[0070] like Figure 2 As shown, the charging communication management method provided by this embodiment, wherein all communication controllers 102 are in a message monitoring state, includes:

[0071] S201: When any communication controller 102 receives a charging request from the corresponding charging pile 103, it determines whether the battery manager 101 is in an idle state. If so, the communication controller 102 establishes a communication channel with the battery manager 101 as the main communication controller and communicates with it. Otherwise, the communication controller 102 is in a message listening state as a slave communication controller.

[0072] Exemplarily, when the communication controller does not monitor the charging communication data in the channel, the battery manager 101 is in an idle state; when the communication controller monitors the charging communication data in the channel, the battery manager 101 is in a charging state.

[0073] It should be noted that the main communication controller is actually the communication controller that first receives the charging request in the charging communication management system 100, that is, the charging communication management system 100 may have only one charging pile 103 corresponding to the communication controller 102 to charge the battery.

[0074] S202: The main communication controller receives the main charging pile parameters fed back by the corresponding charging pile 103, and sends the main charging pile parameter information to the battery manager 101 through the communication channel based on the charging request;

[0075] S203: The battery manager 101 sends battery charging parameters to the main communication controller and receives parameters of the main charging pile; the main communication controller receives the battery charging parameters fed back by the battery manager 101;

[0076] It should be noted that, since all communication controllers 102 are in the message monitoring state, all communication controllers 102 can obtain the battery charging parameters and main charging pile parameter information in the communication channel to facilitate the subsequent steps. Specifically, when any communication controller 102 receives a charging request initiated by the corresponding charging pile, since there is charging communication data in the channel at this time, the communication controller 102 acts as a slave communication controller. At this time, the slave communication controller needs to perform subsequent steps based on the monitored battery charging parameters. The following will explain in detail.

[0077] S204: The slave communication controller communicates with the corresponding charging pile 103 based on the monitored battery charging parameters and other charging communication messages. Specifically, the slave communication controller sends a parameter acquisition signal generated based on the monitored battery charging parameters to the corresponding charging pile 103, receives the slave charging pile parameters fed back by the corresponding charging pile 103, generates slave charging pile parameter information based on the slave charging pile parameters, and broadcasts it;

[0078] S205: The master communication controller sends all monitored slave charging pile parameters to the battery manager 101;

[0079] Since all slave communication controllers broadcast the charging pile parameter information generated by them, the master communication controller can monitor the slave charging pile parameters of all slave communication controllers, thereby enabling the battery manager 101 to obtain the slave charging pile parameters of all slave communication controllers.

[0080] S206: The battery manager 101 receives parameter information of all slave charging piles, generates request parameters based on the battery charging parameters, the parameter information of the master charging pile and the parameter information of all slave charging piles, and sends the request parameters to the master communication controller.

[0081] Based on this, the battery manager 101 formulates the most suitable charging plan based on the actual output capacity of all connected charging piles, and enables all corresponding charging piles to output according to the charging plan through the communication controller 102 to charge the battery.

[0082] Furthermore, the charging communication management method provided in this embodiment also includes:

[0083] S207: All communication controllers 102 communicate with all charging piles 103 based on the request parameters to charge. Specifically, the master communication controller generates charging parameter allocation information based on the request parameters, the master charging pile parameters and all slave charging pile parameters, enters the charging cycle phase based on the charging parameter allocation information, and broadcasts the charging parameter allocation information; the slave communication controller enters the charging cycle phase based on the charging parameter allocation information.

[0084] Among them, entering the charging cycle stage based on the charging parameter allocation information includes each communication controller 102 requesting the corresponding current, voltage and other power output from the corresponding charging pile 103 based on the charging parameter allocation information to charge the battery and enter the charging cycle stage.

[0085] It should be noted that the method for the main communication controller to generate charging parameter allocation information can be found in the above content, and this embodiment will not be described in detail here.

[0086] Furthermore, if Figure 2 As shown, the charging communication management method provided in this embodiment also includes:

[0087] S208: When the main communication controller receives a request to stop charging initiated by the corresponding charging pile 103, the main communication controller disconnects the communication with the battery manager, and the backup communication controller takes over the communication with the battery manager 101 to ensure that the charging process proceeds normally.

[0088] Specifically, the main communication controller selects the backup communication controller from all the slave communication controllers according to a preset screening criterion, and sends a takeover signal to the backup communication controller; the backup communication controller establishes a communication channel with the battery manager 101 based on the takeover signal to serve as the new main communication controller, and its corresponding charging pile parameters are the new main charging pile parameters; at this time, the main communication controller disconnects the communication channel with the battery manager 101 and stops communicating to avoid the disconnection of communication of the charging communication management system 100 due to the disconnection of communication by the main communication controller.

[0089] The master communication controller selects the backup communication controller from all slave communication controllers by a preset screening basis, which may be a slave communication controller with the largest output power of the corresponding charging pile 103, or other specific screening basis to select the backup communication controller. For details, please refer to the above content, which will not be repeated here.

[0090] It should be noted that since the battery manager 101 only communicates with the main communication controller, the communication channel will be affected only when the main communication controller receives a request to stop charging, that is, the backup communication controller needs to be screened only when the main communication controller receives a request to stop charging. When any other slave communication controller receives a request to stop charging from the corresponding charging pile 103, it can directly disconnect from the corresponding charging pile 103, and the main communication controller re-sends all slave charging pile parameter information to the battery manager 101, so that the battery manager 101 can re-formulate a charging plan.

[0091] Based on this, the charging communication management method provided in this embodiment can realize the normal charging process, and the battery manager 101 only communicates with the main communication controller 102. The steps are simple and the communication process is simple, which is conducive to improving the communication efficiency during the charging process.

[0092] In summary, the present application establishes a communication channel only between the main communication controller and the battery manager 101, and all communication controllers 102 are in a message monitoring state, thereby simplifying the communication process while realizing the normal charging process, thereby improving the operation efficiency of the charging communication management system 100. The present application also provides a charging communication management method, which is based on the charging communication management system 100 and is used to realize data interaction during the charging process. The steps are simple, easy to operate, and conducive to achieving better charging effects.
