Description

Technical Field

[0001] This invention belongs to the field of electric vehicle and power grid interaction technology, specifically relating to an electric vehicle and power grid interaction control system and control method. Background Technology

[0002] The main differences between pure electric vehicles and gasoline-powered vehicles lie in four main components: the drive motor, the speed controller, the power battery, and the onboard charger. Unlike gas stations, they are equipped with public ultra-fast charging stations. The quality differences of pure electric vehicles depend on these four components, and their value also depends on their quality. The intended use of pure electric vehicles is also directly related to the selection and configuration of these four components.

[0003] In the charging process for electric vehicles, the interaction between the electric vehicle's local device and the management device of the grid charging station is often required. That is, the electric vehicle's local device transmits the electric vehicle's battery information to the grid charging station's management device, and then the grid charging station's management device uses the charging information based on the electric vehicle's battery information to control the batteries in the grid charging station to charge the electric vehicle in an orderly manner.

[0004] Electric vehicle (EV) local devices and grid charging station management devices typically transmit EV battery information via mobile communication networks. Current mobile communication network efficiency enhancement solutions all employ a constant mode: using a constant congestion detection and recovery system based on the configuration conditions of the mobile communication network hardware and software architecture. However, the dynamic trend of mobile communication networks makes hardware and software performance increasingly complex and difficult to evaluate. Therefore, mobile communication network efficiency enhancement solutions are often only effective in mobile communication network environments where the configuration conditions are met. In addition, with the execution of transmission, the performance of the mobile communication network link changes and fluctuates, which can often have adverse effects, causing EV battery information to be blocked in the transmission channel and hindering the efficiency of EV battery information transmission across the entire channel. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an electric vehicle and power grid interaction control system and method. This system involves constructing a pipeline (PIPE) to receive and transmit battery messages on a battery message transmission channel. The received battery messages are delayed within the pipeline, reducing the load on the pipeline's output battery message transmission and ensuring overall battery message transmission efficiency. The delayed transmission of battery messages from the pipeline prevents channel blockage due to excessive battery message transmission load, thus ensuring the overall efficiency of battery message transmission.

[0006] The present invention employs the following technical solution.

[0008] Step 1: The electric vehicle's local device transmits the electric vehicle's battery information to the management device of the grid charging station.

[0009] Step 2: The management device of the power grid charging station is used to control the batteries in the power grid charging station to charge the electric vehicle in an orderly manner based on the battery information of the electric vehicle.

[0010] Step 1, applied to a local device in an electric vehicle, specifically includes:

[0011] Step 1-1: Construct a pipe PIPE to temporarily store the battery information of the electric vehicle, and set up several layers of sub-pipes for receiving battery information within the pipe PIPE.

[0013] Steps 1-3: Detect the battery messages in the pipeline and perform layering on the battery messages delivered to the pipeline, so that the battery messages that are divided into different layers are collected by the sub-pipes in the pipeline at different layers for receiving battery messages.

[0014] Steps 1-4: Construct a pause region in the pipe to pause battery messages that are blocked in the pipe;

[0015] Steps 1-5: Determine the battery message blocking status of the pipeline PIPE, and transmit the battery message transmitted by the pipeline PIPE according to the battery message blocking status of the pipeline PIPE.

[0016] Preferably, the method for constructing a pipeline (PIPE) and setting several layers of sub-pipelines for receiving battery messages within the pipeline (PIPE) includes:

[0017] Step 1-1-1: Set up a storage field for temporarily storing battery messages in the local device of the electric vehicle that performs battery message transmission, and allow the battery messages of several electric vehicles to be transmitted to the storage field for temporarily storing battery messages.

[0018] Step 1-1-2: Set the storage block of the specified capacity in the storage field where battery messages are temporarily stored as a pipeline PIPE for receiving battery messages, and set the remaining storage block in the storage field where battery messages are temporarily stored as a message transmission field to receive battery messages from several electric vehicles.

[0019] Step 1-1-3: Inside the pipe PIPE, set up several sub-pipes for receiving battery messages from the message transmission domain. After the sub-pipes for receiving battery messages are set up, split the level of the sub-pipes for receiving battery messages so that the sub-pipes at different levels can receive battery messages from the message transmission domain.

[0020] Preferably, steps 1-2 specifically include: deriving the average bit rate of the pipeline PIPE, wherein the number of pipeline PIPE bit rates is consistent with and corresponds one-to-one with the number of battery messages received in the current pipeline PIPE, and the equation for deriving the average bit rate of the pipeline PIPE is:

[0021]

[0022] Here, T is the duration of the segment preceding the moment when the current PIPE receives the a-th battery message, P(Ta) is the average bit rate of the PIPE corresponding to the a-th battery message in this segment, ea is the number of acknowledgment characters returned by the background device after the battery message is received and transmitted to the background device in the segment preceding the moment when the a-th battery message is received, and L(J) is the capacity of the battery message transmitted to the background device corresponding to the J-th acknowledgment character. Both a and J are positive integers.

[0023] The equation for the bit rate limit of the transmission channel, which is predetermined based on the bit rate, is:

[0024]

[0025] Here, G is the number of battery messages received in the current pipeline PIPE, and P(G) is the bit rate limited by the transmission channel.

[0026] Preferably, steps 1-3 specifically include:

[0027] Step 1-3-1: Register each battery message in the delivery pipeline PIPE, and when registering the battery messages, register the order in which the battery messages are delivered;

[0028] Step 1-3-2: Arrange the battery messages in the order they are transmitted, and then divide the arranged sequence into several sections. These sections of battery messages form several levels of battery messages.

[0029] Preferably, steps 1-4 specifically include:

[0030] Step 1-4-1: Set up a storage block for battery messages temporarily stored in the sub-pipes used for receiving battery messages among several sub-pipes. This storage block, which serves as a pause domain, is extracted from the message transmission domain.

[0035] Step 1-5-2: Based on the comparison value, determine whether the transmission can continue as usual. If the comparison value is that the bit rate P(G) limited by the transmission channel is higher than the average bit rate P(Ta) of the pipe PIPE, it is determined that the transmission can continue as usual; otherwise, it is determined that the transmission cannot continue as usual.

[0036] Step 1-5-3: If it is determined that normal transmission can continue, the battery messages in the pipeline PIPE will continue to be transmitted normally;

[0037] Step 1-5-4: When it is determined that normal transmission cannot continue, the storage block belonging to the pause domain is split in the message transmission domain, and the storage block of the pause domain is added to ensure that the pipeline PIPE technology can still receive the transmitted battery messages as usual, and the battery messages stored in the pipeline PIPE and pause domain are transmitted with a delay.

[0041] The local device of the electric vehicle includes a construction module, a detection module, a testing module, a pause module, and a transmission module;

[0042] The construction module is used to construct a pipeline PIPE that temporarily stores battery messages of electric vehicles, and sets up several levels of sub-pipelines for receiving battery messages within the pipeline PIPE.

[0043] The detection module is used to detect the average bit rate of the pipeline PIPE using a blockage identification method, and to pre-set the bit rate limit of the transmission channel based on the average bit rate of the pipeline PIPE.

[0044] The detection module is used to detect battery messages in the pipeline PIPE and to perform layering on the battery messages delivered to the pipeline PIPE, so that the battery messages that are divided into different layers are collected by the sub-pipes in the pipeline PIPE that are used to collect battery messages.

[0045] The pause module is used to construct a pause domain in the PIPE to pause battery messages that are blocked in the PIPE.

[0046] The transmission module is used to determine the battery message blocking status of the pipeline PIPE and to transmit the battery message transmitted by the pipeline PIPE according to the battery message blocking status of the pipeline PIPE.

[0047] Preferably, the construction module is further configured to set a storage domain for temporarily storing battery messages in the local device of the electric vehicle performing battery message transmission, and to allow battery messages from several electric vehicles to be transmitted to the storage domain for temporarily storing battery messages; to set a storage block of a set capacity in the storage domain for temporarily storing battery messages as a pipeline (PIPE) for receiving battery messages, and to set the remaining storage block in the storage domain for temporarily storing battery messages as a message transmission domain for receiving battery messages from several electric vehicles; to set several sub-pipelines for receiving battery messages in the pipeline (PIPE) for receiving battery messages in the message transmission domain, and after the sub-pipelines for receiving battery messages are set up, to split the levels at which the sub-pipelines for receiving battery messages receive battery messages, so that sub-pipelines at different levels receive battery messages in the message transmission domain.

[0056] The transmission module is also used to compare the bit rate limited by the transmission channel derived in steps 1-2 with the current bit rate of battery messages transmitted through the transmission channel, and determine the comparison value between the bit rate limited by the transmission channel P(G) and the current bit rate of battery messages transmitted through the transmission channel; it is used to determine whether normal transmission can continue based on the comparison value. If the comparison value is that the bit rate limited by the transmission channel is higher than the current bit rate of battery messages transmitted through the transmission channel, it is determined that normal transmission can continue; otherwise, it is determined that normal transmission cannot continue; when it is determined that normal transmission can continue, the battery messages in the pipeline PIPE are continued to be transmitted normally; when it is determined that normal transmission cannot continue, the storage blocks belonging to the pause domain are divided in the message transmission domain, and the storage blocks of the pause domain are added to ensure that the pipeline PIPE technology can still receive the transmitted battery messages normally, and the battery messages stored in the pipeline PIPE and the pause domain are transmitted with a delay.

[0059] Figure 2 This is a structural diagram of the local device of the electric vehicle in this invention. Detailed Implementation

[0060] The meanings of some of the technical terms in this invention are as follows:

[0061] The present application will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and should not be used to limit the scope of protection of the present application.

[0062] The present invention discloses a control method for an electric vehicle and power grid interaction control system, such as... Figure 1 As shown, it includes:

[0063] Step 1: The electric vehicle's local device transmits the electric vehicle's battery information to the management device of the grid charging station.

[0064] Step 2: The management device of the power grid charging station is used to control the batteries in the power grid charging station to charge the electric vehicle in an orderly manner based on the battery information of the electric vehicle.

[0065] Step 1, applied to a local device in an electric vehicle, specifically includes:

[0066] Step 1-1: Construct a pipe PIPE to temporarily store the battery information of the electric vehicle, and set up several layers of sub-pipes for receiving battery information within the pipe PIPE.

[0067] In a preferred but non-limiting embodiment of the present invention, the method of constructing a pipeline PIPE and setting several layers of sub-pipelines for receiving battery messages within the pipeline PIPE includes:

[0068] Step 1-1-1: Set up a storage field for temporarily storing battery messages in the local device of the electric vehicle that performs battery message transmission, and allow the battery messages of several electric vehicles to be transmitted to the storage field for temporarily storing battery messages.

[0069] Step 1-1-2: Set the storage block of the specified capacity in the storage field where battery messages are temporarily stored as a pipeline PIPE for receiving battery messages, and set the remaining storage block in the storage field where battery messages are temporarily stored as a message transmission field to receive battery messages from several electric vehicles.

[0070] Step 1-1-3: Inside the pipe PIPE, set up several sub-pipes for receiving battery messages from the message transmission domain. After the sub-pipes for receiving battery messages are set up, split the level of the sub-pipes for receiving battery messages so that the sub-pipes at different levels can receive battery messages from the message transmission domain.

[0071] Steps 1-2: Use the congestion detection method to detect the average bit rate of the pipeline PIPE, and pre-set the bit rate limit of the transmission channel based on the average bit rate of the pipeline PIPE; the transmission channel is the wireless channel between the local device of the electric vehicle and the management device of the grid charging station.

[0072] In a preferred but non-limiting embodiment of the present invention, steps 1-2 specifically include: deriving the average bit rate of the pipeline PIPE, wherein the number of pipeline PIPE bit rates is consistent with and corresponds one-to-one with the number of battery messages currently received in the pipeline PIPE, and the equation for deriving the average bit rate of the pipeline PIPE is:

[0073]

[0074] Here, T is the duration of the segment preceding the moment when the current PIPE receives the a-th battery message, P(Ta) is the average bit rate of the PIPE corresponding to the a-th battery message in this segment, ea is the number of acknowledgment characters returned by the background device after the battery message is received and transmitted to the background device in the segment preceding the moment when the a-th battery message is received, and L(J) is the capacity of the battery message transmitted to the background device corresponding to the J-th acknowledgment character. Both a and J are positive integers.

[0075] The equation for the bit rate limit of the transmission channel, which is predetermined based on the bit rate, is:

[0076]

[0077] Here, G is the number of battery messages received in the current pipeline PIPE, and P(G) is the bit rate limited by the transmission channel.

[0078] By derivation, it can be determined whether the battery message to be transmitted after the pipe PIPE is blocked or exceeds the bit rate of the pre-set transmission channel limit. If it does not exceed the bit rate, the battery message transmission can be performed to maintain the existing rhythm.

[0079] Steps 1-3: Detect the battery messages in the pipeline and perform layering on the battery messages delivered to the pipeline, so that the battery messages that are divided into different layers are collected by the sub-pipes in the pipeline at different layers for receiving battery messages.

[0080] In a preferred but non-limiting embodiment of the present invention, steps 1-3 specifically include:

[0081] Step 1-3-1: Register each battery message in the delivery pipeline PIPE, and when registering the battery messages, register the order in which the battery messages are delivered;

[0082] Step 1-3-2: Arrange the battery messages in the order they are transmitted, and then divide the arranged sequence into several sections. These sections of battery messages form several levels of battery messages.

[0083] After detecting the battery messages in the pipeline PIPE, the battery messages delivered to the pipeline PIPE and the battery messages output to the pipeline PIPE are registered. After the battery messages are registered, the contents of the battery messages delivered to the pipeline PIPE and the battery messages output to the pipeline PIPE are compared to prevent the battery messages from being lost.

[0084] Steps 1-4: Construct a pause region in the pipe to pause battery messages that are blocked in the pipe;

[0085] In a preferred but non-limiting embodiment of the present invention, steps 1-4 specifically include:

[0086] Step 1-4-1: Set up a storage block for battery messages temporarily stored in the sub-pipes used for receiving battery messages among several sub-pipes. This storage block, which serves as a pause domain, is extracted from the message transmission domain.

[0087] Step 1-4-2: Collect the battery messages that are blocked in each sub-pipe used to collect battery messages, and mark the collected battery messages during the battery message collection process.

[0088] Step 1-4-3: Collect battery messages delivered after the pipeline PIPE, and after collection, perform hierarchical arrangement of the newly collected battery messages, so that the newly delivered battery messages are arranged after the blocked battery messages collected by the sub-pipeline used to collect battery messages, thereby reducing the blocking state of battery messages in the pipeline PIPE, delaying the delivery of battery messages, preventing the overall battery message blocking, and ensuring the efficient delivery of overall battery messages.

[0089] Steps 1-5: Determine the battery message blocking status of the pipeline PIPE, and transmit the battery message transmitted by the pipeline PIPE according to the battery message blocking status of the pipeline PIPE.

[0090] In a preferred but non-limiting embodiment of the present invention, steps 1-5 specifically include:

[0091] Step 1-5-1: Based on the bit rate limited by the transmission channel derived in Step 1-2, compare it with the current bit rate of battery messages transmitted through the transmission channel, and determine the comparison quantity between the bit rate limited by the transmission channel P(G) and the current bit rate of battery messages transmitted through the transmission channel.

[0092] Step 1-5-2: Based on the comparison value, determine whether the transmission can continue as usual. If the comparison value is that the bit rate P(G) limited by the transmission channel is higher than the current bit rate of the battery message transmitted through the transmission channel, it is determined that the transmission can continue as usual; otherwise, it is determined that the transmission cannot continue as usual.

[0093] Step 1-5-3: If it is determined that normal transmission can continue, the battery messages in the pipeline PIPE will continue to be transmitted normally;

[0094] Step 1-5-4: When it is determined that normal transmission cannot continue, the storage blocks belonging to the pause domain are split within the message transmission domain, and the storage blocks of the pause domain are increased. This ensures that the pipeline PIPE technology can still receive incoming battery messages as usual, and a delay is performed on the transmission of battery messages stored in the pipeline PIPE and the pause domain. This reduces the load on the transmission of battery messages output by the pipeline PIPE, ensuring the overall efficiency of battery message transmission and improving the overall efficiency of battery message transmission. The delay is set according to specific requirements.
