[0030] Embodiment one

[0031] Figure 1 is a structural schematic diagram of the vehicle-mounted terminal-based charging pile time service device provided by the first embodiment of the present application. As shown in Figure 1 , specifically includes the following steps:

[0032] The charging pile connection module 110 is used to connect with the vehicle-mounted terminal of the vehicle after connecting with the vehicle charging interface of the charging pile;

[0033] The time data request module 120 is used to send a time request to the vehicle-mounted terminal to obtain the system time of the vehicle-mounted terminal;

[0034] The time alignment module 130 is used to send a time alignment request to the vehicle-mounted terminal, and is used to align the timer of the charging pile with the vehicle-mounted terminal;

[0035] The charging strategy execution module 140 is used to receive a charging strategy, and perform charging control according to the time control data in the charging strategy and the alignment result of the timer.

[0036] The present application is applicable to the scene of aligning the timer of the charging pile with the vehicle-mounted terminal, and performing charging control according to the charging strategy. Specifically, the acquisition of the vehicle-mounted terminal system time, the time alignment of the charging pile timer and the control of charging can be performed by the intelligent terminal device, and the highly intelligent charging pile can meet different charging needs of different vehicles to be charged.

[0037] Based on the above use scenario, it can be understood that the execution subject of the present application can be the intelligent terminal device, such as desktop computer, notebook computer, mobile phone, tablet computer and interactive multimedia device, etc., which is not limited here.

[0038] The charging pile connection module 110 can be composed of a micro-processing chip of a computer or the like, and is configured to connect with the vehicle-mounted terminal of the vehicle after the charging pile is connected with the vehicle charging interface.

[0039] The charging pile can be a device for charging electric vehicles and hybrid vehicles, and the like, and is generally composed of a power supply, a control system, a connection line, a charging interface, and the like.

[0040] The vehicle charging interface can be an interface for transmitting electric energy into an electric vehicle battery, and common vehicle charging interfaces include a direct current fast charging interface and an alternating current charging interface. The direct current fast charging interface (DC Fast Charging Port) is also called a fast charging interface or a quick charging interface, and this interface is generally used for fast charging of electric vehicles and can provide large-capacity electric energy in a short time. The alternating current charging interface (AC Charging Port) is mainly used for alternating current charging piles, and the alternating current charging interface is standardized and only allows charging of electric vehicles using the same interface.

[0041] The manner of identifying the connection of the charging pile and the vehicle charging interface can adopt a plugging state test, a current test, a voltage test, and a communication state test, and the like, to identify whether the connection between the charging interface of the charging pile and the vehicle charging interface is established. In the plugging state test, the charging pile can determine whether the connection is established by detecting the insertion or extraction state of the charging gun plug; in the current test, the charging pile can determine whether the connection is established by monitoring the current flowing from the charging pile to the vehicle charging interface, and if there is current flowing, it indicates that the connection is established, and if there is no current flowing, it may indicate that the connection does not exist or has a problem; in the voltage test, the charging pile can determine whether the connection is established by monitoring the voltage between the charging pile and the vehicle charging interface, and if the voltage is normal, it indicates that the connection exists, and if the voltage is abnormal, it may indicate that the connection does not exist or has a problem; in the communication state test, the charging pile and the vehicle charging interface communicate, and the charging pile can determine whether the connection is established by monitoring the communication state, and if the communication is normal, it indicates that the connection exists, and if the communication is abnormal, it may indicate that the connection does not exist or has a problem.

[0042] The vehicle-mounted terminal can be a device installed on a vehicle for providing information systems, entertainment systems, communication systems, and various functions and services, and the vehicle-mounted terminal is generally an integrated electronic device including hardware and software components.

[0043] The connection mode of the charging pile and the vehicle-mounted terminal can adopt wireless communication technology and NFC technology to realize the connection between the charging pile and the vehicle-mounted terminal. The charging pile and the vehicle-mounted terminal can be connected through wireless communication technology. Common wireless connection modes include Bluetooth, Wi-Fi or mobile network, etc. Through wireless connection, the charging pile and the vehicle-mounted terminal can perform data transmission, command control and state monitoring, etc. In addition, some charging piles and vehicle-mounted terminals support NFC (Near Field Communication) technology. By bringing the charging pile and the vehicle-mounted terminal close to each other, a near field communication connection can be established to perform data transmission and identity verification.

[0044] The time data request module 120 can be composed of a microprocessor chip of a computer, etc., and is configured to send a time request to the vehicle-mounted terminal to obtain system time of the vehicle-mounted terminal.

[0045] The time request can be a message for sending to the vehicle-mounted terminal to request system time data. In network communication, a common request message format is a request message based on the HTTP (Hypertext Transfer Protocol) protocol. The HTTP request message mainly includes the following three main parts: a request line including a request method, a URI (Uniform Resource Identifier) and an HTTP protocol version; a request header including additional information about the request, such as a requested host, a content type, authorization information, etc.; and a request body which can include the body data of the request, such as form data or JSON data sent in a POST request. The time request can be sent by the charging pile encapsulating the constructed time request message according to the protocol specification, which can include adding a protocol header and verification information, and finally sending the encapsulated request message to the vehicle-mounted terminal through network connection.

[0046] The system time can be a time value in the vehicle-mounted terminal for indicating the current time. The system time is a clock inside the computer for tracking and recording time changes. The system time can be transmitted by the vehicle-mounted terminal to the charging pile through the network, or transmitted to the charging pile through Bluetooth wireless communication technology.

[0047] The time alignment module 130 can be composed of a microprocessor chip of a computer, etc., and is configured to send a time alignment request to the vehicle-mounted terminal to align the timer of the charging pile with the vehicle-mounted terminal.

[0048] The time alignment request can be a message for sending to the vehicle terminal to request time alignment of the charging pile timer with the vehicle terminal. The charging pile timer can record the charging start time and end time, and calculate the charging duration. The time alignment request can be sent in the following manner: the charging pile encapsulates the constructed time alignment request message according to the protocol specification, which can include adding a protocol header and verification information, and finally sends the encapsulated request message to the vehicle terminal through a network connection.

[0049] The time alignment can be performed in the following manner: the charging pile receives the system time data sent by the vehicle terminal, and changes the time of the timer to be consistent with the system time data. Alternatively, the time alignment can be performed in the following manner: the charging pile and the vehicle terminal are connected to a reliable time server using the NTP (Network Time Protocol) protocol or other similar time synchronization protocols. The time server provides accurate global standard time, and transmits the time information to the charging pile and the vehicle terminal through the protocol, so that the timer of the charging pile is consistent with the system time of the vehicle terminal.

[0050] The charging strategy execution module 140 can be composed of a microprocessor chip or the like of a computer, and is configured to receive the charging strategy and perform charging control according to the time control data in the charging strategy and the alignment result of the timer.

[0051] The charging strategy can include time control data and target power data. If the user does not input the target power data, the target power data is the difference between the vehicle battery capacity and the remaining power. The charging strategy can be received in the following manner: the charging strategy of the charging pile is received through the vehicle terminal, or the charging strategy of the charging pile is obtained through a mobile terminal connected to the charging pile, or the charging strategy of the charging pile is obtained through an operation end of the charging pile.

[0052] The time control data regulates the charging time arrangement, and some regulations are exemplified as follows: when the charging time accumulates to a certain time, the charging needs to be stopped for 10 minutes and then continued to prevent the vehicle battery from being damaged due to high temperature; when the charging time is between 22:00 and 5:00 of the next day (or other charging low peak time period), the charging power can be appropriately reduced to extend the charging time; when the charging time is in the charging peak time period, the charging power can be appropriately increased to reduce the charging time.

[0053] The alignment result of the timer can be the current time displayed by the timer after the time alignment of the timer.

[0054] The charging control can be performed in the following manner: the charging pile starts timing from the moment when the power starts to be delivered, and controls the time length of the delivered power according to the time control data until the charging time is completed.

[0055] In the present solution, the battery data acquisition module is configured to acquire the remaining capacity of the vehicle battery and the performance parameters of the vehicle battery.

[0056] The cable data identification information is configured to identify the cable data of the charging pile.

[0057] The charging strategy adjustment information is configured to determine the maximum charging power according to the remaining capacity and the performance parameters, determine the constraint condition of the charging power according to the cable data, and perform charging strategy adjustment according to the maximum charging power and the constraint condition.

[0058] The remaining capacity of the vehicle battery can refer to the unused or available electric energy capacity of the vehicle battery. The remaining capacity is generally represented by a percentage, indicating the proportion of the remaining capacity of the vehicle battery relative to its full capacity.

[0059] The performance parameters of the vehicle battery can include the following six aspects:

[0060] Battery chemistry: Different types of batteries have different chemical properties and characteristics, so their maximum charging power will also be different. For example, lithium-ion batteries generally have a higher maximum charging power, while lead-acid batteries have a lower maximum charging power.

[0061] Capacity: It can refer to the ability to store and release electric energy, generally represented by ampere-hours (Ah) or kilowatt-hours (kWh). The larger the capacity, the more electric energy the battery can store, and the farther the vehicle can travel.

[0062] Voltage: It can refer to the voltage of the battery in the working state, generally represented by volts (V). Different types of vehicle batteries have different rated voltages. For example, common electric vehicle batteries generally have high voltage (300-400V), while the voltage of the starting battery of traditional cars is 12V.

[0063] Charge-discharge efficiency: It can refer to the energy conversion efficiency of the vehicle battery during charging and discharging. Higher charge-discharge efficiency means less energy loss during charging and discharging.

[0064] Cycle life: It can refer to the ability of the vehicle battery to maintain a certain capacity after multiple charging and discharging cycles. Cycle life can be represented by the number of complete charging and discharging cycles that the battery can perform. Cycle life is an important indicator of battery durability and service life.

[0065] Fast charging capability, which can refer to the ability of a vehicle battery to accept high-power charging in a short time. Having good fast charging capability can enable the battery to reach a high charging level in a short time, improving charging efficiency and convenience.

[0066] The vehicle terminal can store the performance parameter data of the vehicle battery and can record the remaining power of the vehicle battery in real time. The vehicle terminal sends the remaining power data and the performance parameter data to the charging pile to obtain the remaining power and the performance parameter of the vehicle battery.

[0067] Cable data can include the following four aspects:

[0068] Cable type, which can be the type and specification of the cable equipped with the charging pile. For example, common electric vehicle charging pile cable types include Type 1, Type 2, CHAdeMO, and CCS, etc. Different types of cables are suitable for different vehicles and charging standards;

[0069] Rated current, which can refer to the maximum current that the charging pile cable can withstand, generally expressed in amperes (A). The rated current determines the charging speed and power output capability of the charging pile. Different types of charging piles and cables have different rated currents.

[0070] Rated voltage, which can refer to the voltage range suitable for the charging pile cable. It is usually expressed in volts (V). The rated voltage determines which power system and power grid the charging pile is suitable for. Different regions and countries may have different rated voltages.

[0071] Cable length, which can refer to the actual length of the charging pile cable, i.e. the distance from the charging pile to the vehicle charging interface. The length of the cable affects the distance relationship between the vehicle parking position and the charging pile, providing flexibility and convenience.

[0072] Cable data is generally stored in the internal memory of the charging pile. By reading the data in the internal memory, the cable data can be identified.

[0073] Maximum charging power, which can be the maximum power that the charging pile delivers to the vehicle battery during charging. It represents the ability of the charging pile to charge the vehicle battery at the maximum speed. The unit is watts (W). The way to determine the maximum charging power can be to calculate the amount of electricity C that needs to be input to the battery according to the remaining power and capacity of the vehicle battery, and then calculate according to the amount of electricity C, voltage V, charging time t, and charging efficiency η. The calculation formula is as follows:

[0074] Maximum charging power P = (C x η x V) / t

[0075] The constraint condition can be a maximum threshold of the charging power allowed by the cable, in units of watts (W). The constraint condition M can be determined by calculating according to the rated current I and the rated voltage V of the cable, as follows:

[0076] The constraint condition M = I x V

[0077] The charging strategy adjustment can be performed by recalculating a new charging time t according to the constraint condition M, the electric quantity C, the voltage V, and the charging efficiency η, and delivering the electric quantity according to the new charging time t and the constraint condition M, if the maximum charging power P exceeds the constraint condition M, or not adjusting the obtained charging strategy if the maximum charging power P does not exceed the constraint condition M.

[0078] The advantage of this scheme is that by adjusting the charging strategy according to the cable parameters and the remaining electric quantity and performance parameters of the vehicle battery, it can prevent the charging power used during charging from being too large, causing damage to the vehicle battery and the cable, reducing performance, and shortening the service life.

[0079] In the present application example, the charging pile connection module is configured to connect with the vehicle terminal through the charging pile and the vehicle charging interface after the charging pile is connected with the vehicle charging interface; the time data request module is configured to send a time request to the vehicle terminal to obtain the system time of the vehicle terminal; the time alignment module is configured to send a time alignment request to the vehicle terminal to align the timer of the charging pile with the vehicle terminal; and the charging strategy execution module is configured to receive the charging strategy and perform charging control according to the time control data in the charging strategy and the alignment result of the timer. The present technical scheme provides a data basis for intelligent strategy for the charging pile by obtaining the system time of the vehicle terminal, improves the intelligent level of the charging pile, and provides multiple choices for the user's operation mode by obtaining the charging strategy through the vehicle terminal, the mobile terminal, or the operation end of the charging pile, thereby improving the user experience.

[0080] Embodiment Two

[0081] Figure 2 is a structural schematic diagram of a charging pile time service device based on a vehicle terminal provided by Embodiment Two of the present application. The present scheme makes a more optimal improvement on the basis of the above-mentioned embodiments, and the specific improvement is that the charging strategy execution module is specifically configured to: receive the charging strategy of the charging pile through the vehicle terminal; or obtain the charging strategy of the charging pile through the mobile terminal connected with the charging pile; or obtain the charging strategy of the charging pile through the operation end of the charging pile.

[0082] As shown in Figure 2 The device comprises:

[0083] The charging pile connection module 210 is configured to connect with the vehicle terminal of the vehicle after the charging pile is connected with the vehicle charging interface.

[0084] The time data request module 220 is configured to send a time request to the vehicle terminal to obtain the system time of the vehicle terminal.

[0085] The time alignment module 230 is configured to send a time alignment request to the vehicle terminal to align the timer of the charging pile with the vehicle terminal.

[0086] The charging strategy execution module 240 is configured to receive a charging strategy and perform charging control according to the time control data in the charging strategy and the alignment result of the timer.

[0087] The charging strategy execution module 240 is configured to receive the charging strategy of the charging pile through the vehicle terminal, or obtain the charging strategy of the charging pile through the mobile terminal connected with the charging pile, or obtain the charging strategy of the charging pile through the operation end of the charging pile.

[0088] In the mode of receiving the charging strategy of the charging pile through the vehicle terminal, whether the specific information is included in the redundant field of the identified time alignment response data is determined, if yes, a charging strategy acquisition request is sent to the vehicle terminal to acquire the charging strategy of the charging pile through the vehicle terminal.

[0089] In the mode of obtaining the charging strategy of the charging pile through the mobile terminal connected with the charging pile, if the specific information is not included in the redundant field of the time alignment response data, whether the mobile terminal is connected with the charging pile is determined, if yes, a charging strategy acquisition request is sent to the mobile terminal.

[0090] In the mode of obtaining the charging strategy of the charging pile through the operation end of the charging pile, if the mobile terminal is not connected, the charging strategy is obtained through the operation end of the charging pile, and if the input operation of the operation end is not received within the preset time length, the vehicle is controlled according to the default charging strategy.

[0091] The technical scheme has the advantages that the charging strategy of the charging pile is obtained through the vehicle terminal, the mobile terminal and the operation end of the charging pile, or the default charging strategy is adopted to control the vehicle when the input operation is not received within the preset time length, so that the user can input the operation on multiple platforms, the intelligent level is improved, and the use experience of the user is improved.

[0092] Embodiment three

[0093] Figure 3is a structural schematic view of a charging pile time service device based on a vehicle terminal provided in Embodiment Three of the present application. The present scheme is an improved version of the above-mentioned embodiments, and the specific improvement is that the charging strategy execution module is further used to: acquire time alignment response data fed back by the vehicle terminal; identify whether specific information is included in a redundant field of the time alignment response data; if yes, send a charging strategy acquisition request to the vehicle terminal to acquire the charging strategy of the charging pile through the vehicle terminal.

[0094] As shown in Figure 3 the device comprises:

[0095] The charging pile connection module 310 is configured to connect with the vehicle terminal of the vehicle after the charging pile is connected with the vehicle charging interface.

[0096] The time data request module 320 is configured to send a time request to the vehicle terminal to acquire the system time of the vehicle terminal.

[0097] The time alignment module 330 is configured to send a time alignment request to the vehicle terminal to align the timer of the charging pile with the vehicle terminal.

[0098] The charging strategy execution module 340 is configured to receive a charging strategy and perform charging control according to the time control data in the charging strategy and the alignment result of the timer.

[0099] The charging strategy execution module 340 is further configured to: acquire time alignment response data fed back by the vehicle terminal; identify whether specific information is included in a redundant field of the time alignment response data; if yes, send a charging strategy acquisition request to the vehicle terminal to acquire the charging strategy of the charging pile through the vehicle terminal.

[0100] The time alignment response data can be generated by the vehicle terminal after processing the request from the charging pile in the request-response mode of communication, and returned to the charging pile as a response. The time alignment response data can include three parts: status code, response header, and response body. The status code can be a numerical code indicating whether the request is successful or an error occurs. Common status codes include 200 (indicating success), 404 (indicating not found), and 500 (indicating server error). The response header contains metadata information about the response, such as content type, date, and server information. The response body contains the actual data content, which can be text, HTML, JSON, XML, image, audio, or any other data type, depending on the type of request and the support of the server. Specifically, the response body of the time alignment response data can include the system time. Generally, the response body part has redundant fields, which can be repetitive or unnecessary information. Redundant fields can occupy additional space and resources in data storage and processing, but sometimes they are used to improve query or simplify data access. The way to obtain the time alignment response data can be that the vehicle terminal transmits the time alignment response data to the charging pile through the network, or uses Bluetooth wireless communication technology to transmit the time alignment response data to the charging pile.

[0101] The specific information can be information used to inform the charging pile that the charging strategy of the current charging process exists in the data stored by the vehicle terminal. It can be a numerical code or a string. The way to identify the specific information can be to perform string matching on the redundant fields. String matching can be a technique for finding a specified pattern or substring in text. Common string matching algorithms include simple matching algorithm, KMP (Knuth-Morris-Pratt) algorithm, BM (Boyer-Moor) algorithm, and regular expression matching.

[0102] The charging strategy acquisition request can be a message sent to the vehicle terminal to request the vehicle terminal to respond and return the charging strategy data. The way to issue the time alignment request can be that the charging pile encapsulates the constructed charging strategy acquisition request message according to the protocol specification, which can include adding a protocol header and verification information, and finally sends the encapsulated request message to the vehicle terminal through network connection.

[0103] The way to obtain the charging strategy of the charging pile through the vehicle terminal can be that the vehicle terminal transmits the charging strategy data to the charging pile through the network, or uses Bluetooth wireless communication technology to transmit the charging strategy data to the charging pile.

[0104] The technical scheme has the advantages that by identifying whether the specific information is included in the redundant field of the time alignment response data, it is determined whether to acquire the charging strategy of the charging pile through the vehicle terminal, so that the request-response process about whether the vehicle terminal stores the charging strategy between the charging pile and the vehicle terminal can be avoided, the data processing amount is reduced, and the efficiency is improved.

[0112] The charging strategy execution module 440 is further specifically used for: if the specific information is not included in the redundant field of the time alignment response data, identifying whether the charging pile is connected with a mobile terminal; and if the mobile terminal is connected, issuing a charging strategy acquisition request to the mobile terminal.

[0113] The mobile terminal can be a portable terminal device in a mobile communication network, which has the functions of mobile communication, calculation, storage, and internet connection, and is generally a smart phone. The way of identifying whether the charging pile is connected with a mobile terminal can be that the charging pile sends a request information to the mobile terminal, if the mobile terminal returns a response information and the status code in the response information is 200 (indicating success), it is confirmed that the charging pile is connected with the mobile terminal, otherwise, it is confirmed that there is no mobile terminal connected with the charging pile.

[0114] The manner of obtaining the charging strategy of the charging pile by the mobile terminal can be that the mobile terminal transmits charging strategy data to the charging pile through a network, or the mobile terminal transmits the charging strategy data to the charging pile by using Bluetooth wireless communication technology.

[0115] The advantage of the technical solution is that, by identifying whether the mobile terminal is connected to the charging pile and sending a charging strategy obtaining request to the mobile terminal, the charging strategy stored in the mobile terminal can be obtained when the vehicle-mounted terminal does not store the charging strategy, and the user can operate through the mobile terminal, thereby improving convenience and intelligent level.

[0116] Embodiment Five

[0117] Figure 5 is a structural schematic diagram of a charging pile time service device based on a vehicle-mounted terminal provided by the embodiment five of the present application. The present solution is an improved solution based on the above-mentioned embodiments, and the specific improvement is that the charging strategy execution module is further used for: if the mobile terminal is not connected, obtaining the charging strategy through the operation end of the charging pile; and if no input operation of the operation end is received within a preset time length, controlling the vehicle according to a default charging strategy.

[0118] As shown in Figure 5 the device comprises:

[0119] The charging pile connection module 510 is configured to connect with the vehicle-mounted terminal of the vehicle after the charging pile is connected with the vehicle charging interface.

[0120] The time data request module 520 is configured to send a time request to the vehicle-mounted terminal to obtain the system time of the vehicle-mounted terminal.

[0121] The time alignment module 530 is configured to send a time alignment request to the vehicle-mounted terminal to align the timer of the charging pile with the vehicle-mounted terminal.

[0122] The charging strategy execution module 540 is configured to receive the charging strategy and perform charging control according to the time control data in the charging strategy and the alignment result of the timer.

[0123] The charging strategy execution module 540 is further configured to: if the mobile terminal is not connected, obtain the charging strategy through the operation end of the charging pile; and if no input operation of the operation end is received within a preset time length, control the vehicle according to a default charging strategy.

[0124] The operation end of the charging pile can refer to an interface or device used by the user to operate and manage the charging pile. Specifically, it can be a touch screen or a physical button. Some charging piles are equipped with built-in touch screens, and users can perform various operations through the touch screen interface. Some charging piles may have physical buttons, and users can control the start and stop of the charging pile and select charging strategies by pressing the buttons.

[0125] The charging strategy of the charging pile can be obtained through the mobile terminal. The charging pile operation end can transmit charging strategy data to the charging pile through the network. The charging pile can also use a wire to connect the operation end to obtain charging strategy data in a wired transmission manner.

[0126] The preset time length can be adjusted according to the charging low peak period and the charging peak period. For example, the preset time length during the charging low peak period is set to 10 minutes, and the preset time length during the charging peak period is set to 3 minutes.

[0127] The default charging strategy can be a charging strategy suitable for various types of vehicle batteries.

[0128] The benefits of this arrangement are that the charging strategy can be obtained through the operation end of the charging pile, which is convenient for users to use. If no input operation is received from the operation end within the preset time length, the vehicle is controlled according to the default charging strategy, which prevents the charging pile from being unable to charge due to the user forgetting to select the charging strategy, thereby improving the intelligent level and utilization rate of the charging pile.

[0134] S604, receiving a charging strategy and performing charging control according to the time control data in the charging strategy and the alignment result of the timer.

[0135] In this embodiment, after connecting the charging pile to the vehicle's charging interface, it connects to the vehicle's on-board terminal.
