Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

Currently, although electric vehicles have been widely popularized, charging facilities (i.e., charging piles) associated with electric vehicles still do not cover all areas, which leads to a problem that electric vehicles are difficult to charge to some extent. In order to solve the problem, the present application provides an electric vehicle energy management method, an electric vehicle energy management apparatus, a server, and a computer-readable storage medium, which can find other nearby electric vehicles that can provide a charging service when the energy of the electric vehicle is in a rush, and charge the electric vehicle in a timely manner by using an energy transmission technology between the electric vehicles.

In order to realize the technical scheme provided by the application, an electric vehicle energy management system can be constructed firstly. Referring to fig. 1, the electric vehicle energy management system is composed of more than one charging end vehicle (only one is shown in fig. 1), more than one client end vehicle (only one is shown in fig. 1) and a server, and both the client end vehicle and the charging end vehicle can perform data interaction with the server, wherein the client end vehicle is a vehicle that may have a charging service requirement, and the charging end vehicle is a vehicle that can provide the charging service. When an electric vehicle runs and has insufficient energy, the electric vehicle can be used as a client vehicle to send a charging request to a server of an electric vehicle energy management system; after receiving the charging request sent by the client vehicle, the server can find a proper charging end vehicle for the client vehicle in time and inform the charging end vehicle to go to the client vehicle to charge the client vehicle as soon as possible.

In an application scenario, a developer of the electric vehicle energy management system may design a vehicle application program applied to a mobile terminal, and use the vehicle application program as a carrier of a mobile client. The mobile client may establish a connection with the electric vehicle such that a driver is enabled to register the electric vehicle in the electric vehicle energy management system through the mobile client.

In another application scenario, the driver can also directly register the electric vehicle in the electric vehicle energy management system through the on-board unit of the electric vehicle.

It can be understood that each electric vehicle can be registered as a client vehicle and/or a charging-side vehicle in the electric vehicle energy management system, but for an electric vehicle registered as both a client vehicle and a charging-side vehicle, the driver of the electric vehicle must first determine the role of the electric vehicle during the driving process; that is, although one electric vehicle can be registered as both a client vehicle and a charging-side vehicle, it can travel in a road in only one role at a time. For example, an electric vehicle a has registered as both a client vehicle and a charging-end vehicle; if the energy of the electric vehicle A is sufficient in the initial driving stage, a driver can select the electric vehicle A as a charging end vehicle; if the electric vehicle has consumed some energy in a later driving period, causing it to no longer provide charging services for other vehicles or causing its energy to be in a rush, the driver may switch the electric vehicle a from the charging end vehicle to the client vehicle.

In order to explain the technical solution proposed in the present application, the following description will be given by way of specific examples.

Referring to fig. 2, fig. 2 illustrates an energy management method for an electric vehicle according to an embodiment of the present application, which is described in detail as follows:

step 201, receiving a charging request of a client vehicle, where the charging request carries location information of the client vehicle.

In the embodiment of the application, when the energy of the electric vehicle is insufficient, the electric vehicle can be used as a client vehicle to initiate a charging request carrying the position information of the electric vehicle to a server, wherein the position information is expressed in latitude and longitude. The server, upon receiving a charging request sent by a client vehicle, may begin to perform the steps of the electric vehicle energy management method provided by the embodiments of the present application.

Optionally, in the event that the client vehicle is registered in the electric vehicle energy management system via a mobile client, the on-board unit of the client vehicle may synchronize various vehicle parameters of the client vehicle (e.g., parameters of remaining power, speed, location, charging mode, and/or trip destination, etc.) to the mobile client. At the moment, a driver can consult various vehicle parameters of a client vehicle through the mobile client, and autonomously judge whether the client vehicle is in an emergency or not, and when the energy is in the emergency, the driver manually initiates a charging request to the server through the mobile client; or the mobile client can intelligently judge whether the vehicle at the client is in an emergency or not, and when the energy is in the emergency, the mobile client autonomously sends a charging request to the server and outputs a reminding message to remind a driver of parking at the nearest parking place.

Alternatively, in the case where the client vehicle is registered in the electric vehicle energy management system by the on-board unit, the on-board unit may display various vehicle parameters of the client vehicle on its screen in real time. At the moment, a driver can look up various vehicle parameters of a client vehicle through a screen of the vehicle-mounted unit and autonomously judge whether the client vehicle is in an emergency or not, and when the energy is in the emergency, the driver manually initiates a charging request to the server through the vehicle-mounted unit; or the vehicle-mounted unit can intelligently judge whether the client vehicle is in an emergency or not, and when the energy is in the emergency, the vehicle-mounted unit autonomously sends a charging request to the server and outputs a reminding message to remind a driver of parking at the nearest parking place.

Alternatively, a low energy threshold may be preset for the client vehicle; when the mobile client or the vehicle-mounted unit monitors that the residual electric energy of the client vehicle is lower than the low energy threshold, it can be judged that the client vehicle has energy emergency. The low energy threshold may be set by the electric vehicle energy management system or by a driver of the client vehicle, which is not limited herein.

Step 202, based on the position information, the target charging end vehicle is found out in a preset range.

In the embodiment of the application, after the server receives the charging request of the client vehicle, a target charging end vehicle capable of providing the charging service can be found out within a preset range. Specifically, the preset range may be: a circular area formed by taking the current position of the client vehicle as the center of a circle and taking a preset distance (for example, 5 kilo miles) as a radius; or, a square area formed by taking the current position of the client vehicle as the center and taking a preset distance (for example, 10 kilo miles) as the side length; alternatively, it may be an irregular region; alternatively, the administrative region where the current position of the client vehicle is located may also be the administrative region, and the preset range is not limited herein.

Optionally, each charging end vehicle in the electric vehicle energy management system may periodically upload the current location of the charging end vehicle to the server through its on-board unit or the connected mobile client, where the current location may be represented by latitude and longitude, so that the server can quickly determine whether a certain charging end vehicle is within a preset range.

And step 203, sending position information to the target charging end vehicle to indicate the target charging end vehicle to run to the position of the client vehicle and charge the client vehicle.

In the embodiment of the application, after determining the target charging end vehicle, the server may immediately send the location information of the client vehicle to the target charging end vehicle, specifically, send the location information of the client vehicle to an on-board unit of the target charging end vehicle or a mobile client connected to the target charging end vehicle. The target charging end vehicle can navigate according to the position information so as to converge with the client vehicle as soon as possible and provide charging service for the client vehicle. Specifically, the target charging end vehicle can realize energy transmission among electric vehicles through a special charging connector, so that the aim of charging the client side vehicle is fulfilled. The following is a brief description of the process of charging the client vehicle by the target charging-end vehicle: arranging a discharging end of the charging connector at the target charging end vehicle, so that the target charging end vehicle enters a discharging state; arranging a charging end of the charging connector at the client vehicle so that the client vehicle enters a charging state; after the target charging end vehicle enters a discharging state and the client vehicle enters a charging state, electric energy is transmitted to the client vehicle from the target charging end vehicle, and energy supplement of the client vehicle is achieved.

Referring to fig. 3, in order to find the most suitable target charging-end vehicle for the client vehicle, fig. 3 is a flowchart illustrating a second method for energy management of an electric vehicle according to an embodiment of the present disclosure. In this embodiment of the present application, a batch of idle charging end vehicles within a preset range is first found, and then a target charging end vehicle is determined from the batch of idle charging end vehicles, where step 301 is the same as step 201, and step 304 is the same as step 203, and details are not repeated here:

step 301, receiving a charging request of a client vehicle, where the charging request carries location information of the client vehicle.

Step 302, based on the position information, finding an idle vehicle set in a preset range, wherein the idle vehicle set comprises currently idle charging end vehicles.

In the embodiment of the present application, each charging-end vehicle may upload, to the server, an operating status thereof in addition to its own current location, where the operating status includes: idle state, occupied state, and reservation state. The idle state is used for indicating that the charging end vehicle is currently idle, the occupied state is used for indicating that the charging end vehicle is currently providing charging service for a certain electric vehicle, and the reserved state is used for indicating that the charging end vehicle is currently reserved for the charging service by the certain electric vehicle. In order to reduce the waiting time of the client vehicles, after all the charging end vehicles in a preset range are obtained, preliminary screening can be performed according to the charging states of the charging end vehicles, and an idle vehicle set is obtained. In the idle vehicle set, only the currently idle charging end vehicles, that is, only the charging end vehicles in the idle state are reserved.

Step 303, determining a target charging end vehicle in the idle vehicle set.

In the embodiment of the application, as long as the idle vehicle set is not empty, it can be determined that a currently idle charging-end vehicle exists within the preset range. At this time, the charging-end vehicles which are occupied or reserved can be not considered any more, and only the currently idle charging-end vehicle can be considered, so that the waiting time of the client vehicle is avoided being too long.

And step 304, sending position information to the target charging end vehicle to indicate that the target charging end vehicle runs to the position of the client vehicle and charges the client vehicle.

Optionally, in order to sufficiently meet the driving requirement of the client vehicle, the step 303 includes:

and A1, respectively calculating the available electric energy of each charging end vehicle in the idle vehicle set.

In the embodiment of the application, each charging-end vehicle can also report vehicle parameters such as residual electric energy, reserved running distance, running efficiency, battery information, purchase price, supported charging mode and the like to the server periodically. The reserved running distance is used for indicating the running distance required by the charging end vehicle after the charging end vehicle provides the charging service, that is, the charging end vehicle needs to at least keep the self energy to be capable of running the reserved running distance. The driving efficiency can be theoretical driving efficiency or actual driving efficiency, wherein the theoretical driving efficiency can be obtained through the description of the electric vehicle of the charging end vehicle; the actual running efficiency can be calculated by formula

Calculated as in the above formula, η_factFor the actual driving efficiency, effective _ driving _ distance is the effective driving mileage, and effective _ energy _ contribution is the effective consumed energy. In the embodiment of the present application, the unit of the driving efficiency may be kilometers per kilowatt hour or miles per kilowatt hour, which is not limited herein. The battery information is used to indicate various battery parameters of the charging-side vehicle, including a total battery storage amount, a depth of discharge (DoD), a cycle life, and the like, and is not limited herein. The charging mode may include an ac charging mode, a dc charging mode, a wireless charging mode, and the like, which is not limited herein. The server can use the vehicle parameters to calculateThe available electric energy of each charging end vehicle in the idle vehicle set is calculated.

Alternatively, the available electric energy of the charging-end vehicle can be calculated by the following formula:

energy _ S is available electric Energy of the charging end vehicle; e _ storage is the residual electric energy of the charging end vehicle; dist _ S is a reserved running distance of a charging end vehicle; eta _ S is the running efficiency of the charging end vehicle; charging _ efficiency is Charging efficiency.

And A2, respectively calculating the electric energy to be consumed when each charging end vehicle charges the client side vehicle.

In the embodiment of the present application, when the charging-side vehicle charges the client vehicle, the charging-side vehicle needs to travel to the client vehicle before the charging-side vehicle starts the charging operation. Therefore, the electric energy consumed by the charging-side vehicle when the charging-side vehicle travels to the client vehicle should be included in the electric energy to be consumed when the charging-side vehicle charges the client vehicle. Meanwhile, it is also generally desirable that a client vehicle can obtain enough electric energy to reach a place where the client vehicle wants to reach after one-time charging so as to reduce the number of charging times as much as possible. Based on this, step a2 can be embodied as:

and A21, determining a target position to be driven by the client vehicle.

In an application scenario, if the client vehicle starts the navigation function and obtains the travel destination of the current travel input by the driver of the client vehicle, the client vehicle may carry the travel destination in the charging request initiated by the client vehicle. Under the condition that the charging request carries a travel destination, the travel destination is a place which the client vehicle wants to reach after charging is completed; the server may directly determine the travel destination as a target location for the client vehicle to travel.

In another application scenario, if the client vehicle does not start the navigation function and cannot obtain the travel destination of the current travel input by the driver of the client vehicle, the travel destination is not carried in the charging request initiated by the client vehicle. For example, when an electric taxi without passengers runs on a road, a driver of the electric taxi usually does not have a specific destination, and in such an application scenario, when the electric taxi is used as a client vehicle to initiate a charging request, since the driver does not input a trip destination, the charging request does not carry the trip destination. At this time, because the travel destination of the client vehicle is unknown and the energy of the client vehicle is already in a rush, considering that the cost required for charging at the charging pile is often less than the cost required for charging by calling the charging end vehicle, under the condition that the charging request does not carry the travel destination, the charging pile closest to the client vehicle can be searched as the target charging pile, and the target charging pile is defaulted as the place which the client vehicle wants to reach after the charging of the calling target charging end vehicle is completed; the server can determine the target charging pile as a target place to be driven by the client vehicle. Through the process, the client vehicle can call the target charging end vehicle through the scheme provided by the embodiment of the application under the condition that the route destination is not specified, only the target charging end vehicle needs to acquire enough energy needed by the nearest charging pile, and the subsequent energy supply can be operated through the nearest charging pile so as to reduce charging cost.

And A22, calculating the distance to be traveled of the client vehicle according to the target location and the position information.

In the embodiment of the application, the server determines the distance required by the client vehicle to travel to the target location as the distance to be traveled, so that the server can plan the route to be traveled for the client vehicle according to the target location of the client vehicle and the position information of the client vehicle, and calculate the distance to be traveled corresponding to the route to be traveled.

And A23, calculating the inter-vehicle travel distance of the charging end vehicle according to the current position and the position information of the charging end vehicle for each charging end vehicle in the idle vehicle set.

In the embodiment of the application, the server determines the distance required by the charging end vehicle to the client vehicle as the inter-vehicle distance, so that for each charging end vehicle in the idle vehicle set, the server can calculate the inter-vehicle distance of each charging end vehicle according to the current position of the charging end vehicle and the position information of the client vehicle.

And A24, calculating the electric energy to be consumed of the vehicle at the charging end according to the vehicle-to-vehicle running distance and the distance to be traveled.

In the embodiment of the application, the energy to be consumed for charging the charging end vehicle for the client vehicle is specifically composed of two parts: the first portion is a fixed portion and the second portion is a variable portion. Wherein, the fixed part is: the energy required by the client vehicle for running the distance to be traveled; the variable part is as follows: the energy required for the charging end vehicle to travel to the client vehicle.

Alternatively, the electric energy to be consumed of the charging-end vehicle may be calculated by the following formula:

wherein Energy _ C is the electric Energy to be consumed of the charging end vehicle; DD is the distance between the charging end vehicle and the client end vehicle, and is calculated in step a 23; dist _ C is the distance to be traveled by the client vehicle, and is specifically calculated in step a 22; eta _ C is the running efficiency of the client vehicle; η _ S is the running efficiency of the charging-end vehicle. It can be seen that for each charging end vehicle in the set of idle vehicles, Dist _ C/η _ C is only associated with the client vehicle, and its value does not change, i.e. Dist _ C/η _ C is a fixed part that constitutes the electrical energy to be consumed; the DD/eta _ S is related to each charging end vehicle, and the values of the DD/eta _ S corresponding to different charging end vehicles are different, namely the DD/eta _ S is a variable part forming the electric energy to be consumed.

And A3, determining the charging end vehicle which can provide the electric energy larger than the electric energy to be consumed in the idle vehicle set as the target charging end vehicle.

In the embodiment of the present application, however, the charging-end vehicle which can provide the electric energy larger than the electric energy to be consumed can provide the electric energy enough for the client-end vehicle to travel to the target site. Thus, a charging end vehicle that can provide more electric energy than is to be consumed may be determined as the target charging end vehicle in the idle vehicle set.

Alternatively, if there are a plurality of charging end vehicles in the idle vehicle set, which can provide electric energy greater than the electric energy to be consumed, the charging end vehicles, which can provide electric energy greater than the electric energy to be consumed, need to be further screened to determine only one target charging end vehicle. The screening mode adopted by the server can be random screening, namely, a charging end vehicle which can provide electric energy larger than the electric energy to be consumed is randomly determined from the idle vehicle set to be a target charging end vehicle; alternatively, the screening may be based on a particular evaluation dimension. For example, the evaluation dimension may be the expected revenue for the charging-end vehicle, then step A3 may be embodied as:

and B1, respectively calculating the expected benefit of charging the client vehicle by the charging end vehicle which can provide the electric energy larger than the electric energy to be consumed in the idle vehicle set.

In the embodiment of the application, the purchase price and the battery information can be obtained from the vehicle parameters reported by each charging end vehicle, the battery loss of each charging end vehicle can be obtained from the battery information, and then the expected income of each charging end vehicle for charging the client side vehicle can be calculated and obtained by using a preset income calculation formula based on the purchase price, the battery loss and the electric energy to be consumed of each charging end vehicle and the preset sale price of the electric vehicle energy management system. The revenue calculation formula may be:

Revenue＝Energy_C*Charging_price-Energy_C*(P_initial+Cost_d)

wherein, Revenue is expected income; energy _ C is the electric Energy to be consumed of the charging end vehicle; the Charging _ price is a preset selling price; p _ initial is the purchase price of the charging end vehicle; cost _ d is the battery loss.

And B2, determining the charging end vehicle with the largest expected profit as the target charging end vehicle.

In the embodiment of the present application, in order to create the maximum benefit to the driver of the charging-end vehicle, the charging-end vehicle whose expected benefit calculated is the maximum may be determined as the final target charging-end vehicle. Therefore, in the behavior that the target charging end vehicle provides the charging service for the client vehicle, the client vehicle can obtain the convenient charging service, and the target charging end vehicle can obtain a certain reward, so that mutual profit and win-win between the two parties are realized.

Of course, the target charging-end vehicle may be determined from other evaluation dimensions according to different application scenarios, and is not limited herein. For example, if the target Charging end vehicle is determined from the evaluation dimension of the Charging expense paid by the client vehicle, the Charging end vehicle with the minimum Charging expense may be determined as the target Charging end vehicle, and the Charging expense may be calculated by Energy _ C _ Charging _ price, that is, the Charging expense paid by the client vehicle calling the Charging end vehicle may be obtained by multiplying the electric Energy to be consumed by the Charging end vehicle by the preset selling price.

Therefore, according to the embodiment of the application, the server can find the charging end vehicle capable of providing enough electric energy for the client side vehicle as the target charging end vehicle through the electric energy to be consumed and the electric energy to be provided of each charging end vehicle. And when a plurality of charging end vehicles capable of providing enough electric energy for the client vehicle are available, the final target charging end vehicle can be screened out according to the expected income of the charging end vehicle, and the win-win situation of the client vehicle and the target charging end vehicle is realized.

In order to provide richer charging possibilities and improve the flexibility of charging a charging-side vehicle to a client-side vehicle, fig. 3 shows a schematic flow chart of a third electric vehicle energy management method provided in the embodiment of the present application, different charging modes may be analyzed to determine a target charging-side vehicle, where step 401 is the same as step 301, step 402 is the same as step 302, step 404 is the same as step a2, and step 406 is the same as step 304, and details are not repeated here:

step 401, receiving a charging request of a client vehicle, where the charging request carries location information of the client vehicle.

And step 402, searching for an idle vehicle set in a preset range based on the position information, wherein the idle vehicle set comprises the current idle charging end vehicle.

And step 403, respectively calculating the available electric energy of each charging end vehicle in the idle vehicle set in the specified charging mode.

In the embodiment of the application, if a charging request initiated by a client vehicle carries the charging modes supported by the client vehicle, each charging mode supported by the client vehicle is determined as a specified charging mode; and if the charging request initiated by the client vehicle does not carry the charging modes supported by the client vehicle, determining all currently developed charging modes as the specified charging modes. As can be seen, multiple charging modes may be included in a given charging mode.

Alternatively, on the basis of step a1, the calculation formula of the available electric energy of the charging-end vehicle may be refined as:

energy _ s (mode) is available for the charging-end vehicle in a specific charging mode; charging _ efficiency (mode) is the Charging efficiency of the Charging end vehicle in a specific mode; other parameter meanings can be referred to the specific explanation of step A1, and are not described herein. Based on the calculation, the available electric energy of each charging-end vehicle in the specified charging mode can be calculated. For example, if the designated charging mode is an ac charging mode, a dc charging mode, or a wireless charging mode, the server may calculate Energy _ s (ac), Energy _ s (dc), and Energy _ s (wireless) of the charging-end vehicle, where Energy _ s (ac) represents the available power of the charging-end vehicle in the ac charging mode, Energy _ s (dc) represents the available power of the charging-end vehicle in the dc charging mode, and Energy _ s (wireless) represents the available power of the charging-end vehicle in the wireless charging mode.

And step 404, respectively calculating the electric energy to be consumed when each charging end vehicle charges the client side vehicle.

Step 405, determining that the charging-end vehicle capable of providing the electric energy greater than the electric energy to be consumed in the charging mode in the idle vehicle set is the target charging-end vehicle.

In this embodiment, assuming that the currently developed charging modes include three types, i.e., an ac charging mode, a dc charging mode, and a wireless charging mode, and the difference between the available power and the power to be consumed of the charging-end vehicle is recorded as Delta _ E, step 405 may have the following application scenarios:

in an application scenario, the charging request initiated by the client vehicle does not carry the charging mode supported by the client vehicle, and at this time, since the charging mode supported by the client vehicle is unknown, all developed charging modes are determined as the designated charging mode in order to comprehensively meet the requirements of the client vehicle. In such an application scenario, the charging-end vehicle is required to support all charging modes, and the available power in each charging mode is greater than the power to be consumed. That is, in this application scenario, only the charging-end vehicle that simultaneously supports the ac charging mode, the dc charging mode, and the wireless charging mode and satisfies Delta _ e (ac), Delta _ e (dc), and Delta _ e (wireless) that are all greater than 0 can be determined as the target charging-end vehicle, where Delta _ e (ac) represents a difference between the available power and the power to be consumed of the charging-end vehicle in the ac charging mode; delta _ E (DC) represents the difference value between the available electric energy and the electric energy to be consumed of the charging end vehicle in the direct current charging mode; delta _ E (wireless) represents the difference between the available power and the power to be consumed of the charging end vehicle in the wireless charging mode.

In another application scenario, the charging request initiated by the client vehicle carries the charging mode supported by the client vehicle, and at this time, the charging mode supported by the client vehicle is known, so that the requirement of the client vehicle can be met in a targeted manner. In this application scenario, it is only required that the charging mode supported by the charging-end vehicle matches any one of the charging modes supported by the client vehicle, and the available power in at least one of the matching charging modes is greater than the power to be consumed. For example, if the client vehicle only supports the ac charging mode and the dc charging mode, the target charging end vehicle needs to support the ac charging mode and/or the dc charging mode, and the target charging end vehicle needs to satisfy Delta _ e (ac) and/or Delta _ e (ac) greater than 0.

And 406, sending position information to the target charging end vehicle to indicate that the target charging end vehicle runs to the position of the client vehicle and charges the client vehicle.

Optionally, if there are a plurality of charging end vehicles in the idle vehicle set, which can provide the electric energy greater than the electric energy to be consumed in the designated charging mode, the charging end vehicles, which can provide the electric energy greater than the electric energy to be consumed in the designated charging mode, need to be further screened to determine a unique target charging end vehicle. Based on this, step 405 may be embodied as:

and C1, in each designated charging mode, determining the charging end vehicle with the highest expected profit as the candidate charging end vehicle in the corresponding designated charging mode.

In this embodiment of the present application, in a specific charging mode, the expected profit calculation formula may specifically be:

Revenue(mode)＝Energy_C*Charging_price(mode)-Energy_C*(P_initial+Cost_d)

wherein, revenue (mode) is the expected benefit in the specified charging mode; charging _ price (mode) is a selling price of electricity under a specified Charging mode preset by an energy management system of the electric vehicle; other parameter meanings can be referred to the specific explanation of step B1, which is not repeated herein. Through the calculation formula, the expected profit of each charging-end vehicle in the specified charging mode can be obtained. For example, assuming that the designated charging mode is an ac charging mode, a dc charging mode, or a wireless charging mode, the revenue (ac), the revenue (dc), and the revenue (wireless) of each charging-end vehicle can be calculated respectively, and candidate charging-end vehicles in each designated charging mode can be obtained by screening.

And C2, pushing the charging information of the candidate charging end vehicles in each charging mode to the client vehicle so that the client vehicle can select the target charging end vehicle based on the charging information.

In the embodiment of the present application, the charging information may be charging time and charging expense of the candidate charging-end vehicle in the corresponding specified charging mode. The charging time can be estimated according to the charging efficiency of the candidate charging end vehicle in the corresponding charging mode and the electric energy to be consumed of the candidate charging end vehicle; the charging expense can be estimated according to the selling price of the candidate charging end vehicle in the corresponding appointed charging mode and the electric energy to be consumed of the candidate charging end vehicle. By pushing the charging information of the candidate charging end vehicle in each specified charging mode to the client vehicle, the driver of the client vehicle can conveniently and quickly make a selection.

And C3, receiving a selection instruction of the client vehicle, and determining a target charging end vehicle based on the selection instruction.

In the embodiment of the present application, the candidate charging end vehicle selected by the driver of the client vehicle is determined as the target charging end vehicle.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating the interaction flow between the client vehicle and the server when the server performs steps C1-C3. Here, the steps other than steps C1 to C3 are not shown in fig. 5 and are omitted by broken lines. Through C1-C3, the driver of the client vehicle is provided with more selection possibilities, and the driver of the client vehicle can determine the target charging end vehicle according to the requirement of the driver.

For ease of understanding, specific application scenario explanation steps C1 through C3 are given below:

in a first application scenario, if a charging request initiated by a client vehicle does not carry a charging mode supported by the client vehicle, the charging mode is designated as an alternating current charging mode, a direct current charging mode and a wireless charging mode. The server may determine that Car _ S _ AC, Car _ S _ DC, and Car _ S _ wireless are candidate charging end vehicles in the corresponding designated charging mode, where the charging end vehicle with the highest revenue (AC) is denoted as Car _ S _ AC, the charging end vehicle with the highest revenue (DC) is denoted as Car _ S _ DC, and the charging end vehicle with the highest revenue (wireless) is denoted as Car _ S _ wireless. The server pushes the charging information of Car _ S _ AC, Car _ S _ DC and Car _ S _ wireless to the vehicle-mounted unit of the client vehicle or the connected mobile client, the driver of the client vehicle selects a target charging terminal vehicle from the Car _ S _ AC, the Car _ S _ DC and the Car _ S _ wireless, and the selection result is returned to the server. The server performs subsequent operations based on the target charging-end vehicle selected by the driver.

In a second application scenario, the charging request initiated by the client vehicle carries the charging modes supported by the client vehicle, and the client vehicle supports only one charging mode, so that the server can directly screen the charging-end vehicle with the largest expected profit from the charging modes supported by the client vehicle as the target charging-end vehicle.

In a third application scenario, the charging request initiated by the client vehicle carries the charging modes supported by the client vehicle, and there are more than two charging modes supported by the client vehicle, so that the server can use the charging-end vehicle with the highest expected profit in each charging mode supported by the client vehicle as a candidate target charging-end vehicle. For example, if the client vehicle supports only the ac charging mode and the dc charging mode, the charging mode is designated as the ac charging mode and the dc charging mode. If the vehicle at the charging end with the highest revenue (AC) is denoted as Car _ S _ AC, and the vehicle at the charging end with the highest revenue (DC) is denoted as Car _ S _ DC, the server may determine that Car _ S _ AC and Car _ S _ DC are candidate charging end vehicles in the corresponding designated charging mode. And pushing the charging information of both Car _ S _ AC and Car _ S _ DC to an on-board unit of the client vehicle or a connected mobile client, selecting a target charging terminal vehicle from the Car _ S _ AC and the Car _ S _ DC by a driver of the client vehicle, and returning the selection result to the server. The server performs subsequent operations based on the target charging-end vehicle selected by the driver.

Therefore, according to the embodiment of the application, the server can screen the target charging terminal vehicles for the client screen according to the charging mode supported by the client vehicle. When the charging modes supported by the client vehicle are more, the candidate charging end vehicles in each charging mode supported by the client vehicle can be screened out, and the final option of the target charging end vehicle is given to the driver of the client vehicle. The process can provide richer charging possibilities for the client vehicle and meet different requirements of the client vehicle.

Alternatively, in order to help the driver of the target charging-side vehicle to quickly identify the client vehicle waiting for charging, after

steps

202, 303, and 405, the server may obtain vehicle information of the client vehicle, which is used to identify the client vehicle, and send the vehicle information of the client vehicle to the target charging-side vehicle, which may be license plate information and/or model information of the client vehicle, and the like, and is not limited herein.

Optionally, in order to help the driver of the client vehicle to quickly identify the target charging end vehicle providing the charging service, after

steps

202, 303, and 405, the server may further obtain vehicle information of the target charging end vehicle, where the vehicle information is used to identify the target charging end vehicle, and the vehicle information may be license plate information and/or model information of the target charging end vehicle, and the like, and is not limited herein.

Optionally, in order to achieve the disclosure and transparency of the charging expense, after

steps

202, 303 and 405, the server may further estimate the charging expense of the target charging end vehicle based on the electric energy to be consumed and the preset selling price of the target charging end vehicle, and transmit the charging expense of the target charging end vehicle to the on-board unit of the client vehicle or the connected mobile client.

Referring to fig. 6, fig. 6 shows an application scenario of the energy management method for an electric vehicle according to the embodiment of the present application. After the vehicle A is fully charged at home through a solar energy, wind energy or other new energy charging modes, the vehicle A can be used as a charging end vehicle to run on the road; the destination of the journey of the vehicle B is point C, but the energy of the vehicle B is only 20% left, and the vehicle B is not enough to be supported to reach the destination of the journey, and at the moment, the vehicle B can be used as a client vehicle to initiate a charging request; the server finally determines the vehicle A as a target charging end vehicle through the electric vehicle energy management method provided by the embodiment of the application, and sends the current position of the vehicle B to the vehicle A; after receiving the current position of the vehicle B, the vehicle a travels to the current position of the vehicle B to merge with the vehicle B and provide the vehicle B with the charging service.

Therefore, according to the embodiment of the application, if the energy is in a hurry in the running process of the electric vehicle, a charging request is sent to the server and the electric vehicle waits on site, and a driver of the electric vehicle is not required to search for the charging pile all around; the server can automatically search and quickly determine a target charging end vehicle capable of providing charging service in a certain range based on the charging request, inform the target charging end vehicle to arrive at an electric vehicle with urgent energy as soon as possible, and provide the charging service for the electric vehicle with urgent energy through an energy transmission technology among the electric vehicles. Through the process, when the electric vehicle has the charging requirement, the driver who no longer needs the electric vehicle searches for the charging pile everywhere, so that the operation flow of the driver can be simplified on the one hand, and the time consumed by the driver for searching for the charging pile can be reduced on the other hand. In the process, the client vehicle side gives a certain reward to the charging end vehicle side, namely, the charging end vehicle can benefit from the action of providing the charging service, and the win-win situation of the client vehicle and the charging end vehicle is realized.
