Meanwhile, relational terms such as "first," "second," and the like may be used solely in the description to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

At present, from the development of market situation, the application of power batteries is more and more extensive, and the power batteries are not only applied to energy storage power supply systems of hydraulic power, firepower, wind power, solar power stations and the like, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles and the like. With the continuous popularization of electric vehicles, the electric vehicles need to be charged in a charging station when the electric quantity is low.
The inventors noted that: when charging to electric vehicle, usually look for by oneself by the car owner in the charging station and fill electric pile and charge, when the charging station is great, the car owner need look for idle electric pile that fills by oneself in the charging station, and efficiency is lower. When a large number of vehicles to be charged exist, a plurality of vehicles to be charged search for the idle charging pile in the charging station, and the congestion phenomenon is easy to occur. Furthermore, for the vehicle which needs to be charged urgently (the electric quantity is extremely low or the special vehicle, such as a fire fighting vehicle, an ambulance and the like), the vehicle which needs to be charged urgently needs to search for the idle charging pile by itself, and the prior charging service cannot be provided.
In order to solve the problems that the existing electric vehicle is low in efficiency and easy to block in the charging process of a charging station and cannot flexibly provide charging service for the vehicle which needs to be charged, the inventor of the application finds that the charging pile can be uniformly distributed to the vehicle which needs to be charged in the charging station by acquiring the vehicle information of the vehicle which needs to be charged in the charging station within a period of time, on one hand, the time for searching the charging pile can be shortened, the blocking phenomenon in the charging station can be reduced, and on the other hand, the vehicle which needs to be charged can preferentially provide the charging service for the vehicle which needs to be charged.
In view of the above, embodiments of the present application provide a charging management method, device, system, electronic device, and storage medium, so as to solve the problems that an existing electric vehicle is inefficient, easily jammed and unable to flexibly provide a charging service for a vehicle that is in urgent need of charging in a charging station during charging.
The electric vehicle in the embodiment of the present application includes, but is not limited to: electric vehicles such as electric bicycles, electric motorcycles, and electric automobiles.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a charging management apparatus according to an embodiment of the present disclosure. The charge management device 100 includes: an antenna 101, a reader/writer 102, and a controller 103.
The charging management device 100 may be disposed in a charging station, the antenna 101 is connected to the reader/writer 102, and when a vehicle to be charged passes through the antenna 101, the reader/writer 102 obtains the electric quantity information and the vehicle type in the electronic tag of each vehicle to be charged from the electronic tag of each vehicle to be charged through the antenna 101. The controller 103 is connected with the reader-writer 102, determines the priority of each vehicle to be charged according to the electric quantity information and the vehicle type acquired by the reader-writer 102, and distributes charging piles according to the priority of each vehicle to be charged.
In some embodiments, as shown in fig. 1, one charging post is provided with one charging management device 100. Each charging management device 100 acquires the electric quantity information and the vehicle type in the electronic tag of the vehicle to be charged near the charging pile, determines the priority of each vehicle to be charged according to the electric quantity information and the vehicle type, and distributes the charging pile according to the priority of each vehicle to be charged.
In other embodiments, as shown in fig. 2, a plurality of charging piles (corresponding to charging pile 1, charging pile 2, charging pile 3, and charging pile 4 in fig. 2) adjacent to each other in the charging station share one charging management device 100. The charging management device 100 acquires the electric quantity information and the vehicle type in the electronic tag of the nearby vehicle to be charged, determines the priority of each vehicle to be charged according to the electric quantity information and the vehicle type, and allocates a plurality of adjacent charging piles according to the priority of each vehicle to be charged.
In order to enable data sharing among the charging management devices 100, so that all charging piles in the entire charging station can be uniformly distributed, each charging management device 100 may further include a wireless communication module, which is connected to the controller 103, and data sharing among the charging management devices 100 may be implemented through the wireless communication module.
In the above embodiment, the controller 103 on one or more of the plurality of charge management devices 100 may be designated to allocate all the charging posts in the entire charging station.
An electronic tag is embedded in a Battery Management System (BMS) of each vehicle to be charged, and a BMS module and the electronic tag can be connected by communication interfaces such as a Serial Peripheral Interface (SPI), an Integrated Circuit Bus (IIC), a Universal Asynchronous Receiver/Transmitter (UART), a Universal Serial Bus (USB), and the like, and data is transmitted in a differential signal form, so that the Battery Management System (BMS) has high interference resistance.
The electronic tag serves as a unique identity of a battery in the vehicle to be charged, and the vehicle type of the vehicle to be charged can be configured in the electronic tag in advance. The electronic tag can be an active electronic tag and has multiple writing and erasing functions. The active electronic tag is selected, so that the communication distance and the communication quality of the whole system can be greatly increased.
The BMS module acquires battery information of the vehicle to be charged and writes the battery information into the electronic tag. It is understood that the battery information of the vehicle to be charged may be constantly changed as the vehicle to be charged travels. And setting a collection time interval, wherein the time interval is preset, and the BMS module collects the battery information of the vehicle to be charged and updates the battery information in the electronic tag.
When a plurality of vehicles to be charged enter the receiving range of the antenna 101, the reader/writer 102 wirelessly and remotely reads the battery information and the vehicle type in the electronic tag on the vehicle to be charged through the antenna 101, and sends the battery information and the vehicle type to the controller 103. The controller 103 determines the priority of each vehicle to be charged according to the received battery information and the vehicle type, and then allocates charging piles according to the priority of each vehicle to be charged.
In some embodiments, the electronic tag and the reader 102 communicate wirelessly using Radio Frequency Identification (RFID) technology. The communication frequency band can be selected from an ultra-high frequency band (the frequency is 860 MHz-960 MHz, and the bandwidth is 100 MHz). The ultrahigh frequency communication frequency range is selected so that the communication distance can reach more than 100 meters. The reader-writer 102 supports multi-tag reading and writing, and can simultaneously acquire battery information and vehicle types of a plurality of vehicles to be charged when the plurality of vehicles to be charged exist within the communication range of the antenna 101.
It should be noted that the above-mentioned wireless communication between the electronic tag and the reader/writer 102 by using the RFID technology is only an example provided in the present application, and the embodiment of the present application does not specifically limit the wireless communication technology used between the electronic tag and the reader/writer 102. For example, the electronic tag is an electronic tag of other communication methods besides the rfid technology, and the reader/writer 102 can perform wireless communication with the electronic tag through other communication methods.
When the controller 103 determines the priority of each vehicle to be charged according to the electric quantity information and the vehicle type, the following steps are specifically performed: for each vehicle to be charged, determining a first priority of the vehicle to be charged according to the electric quantity information of the vehicle to be charged; determining a second priority of the vehicle to be charged according to the vehicle type of the vehicle to be charged; and determining the priority of the vehicle to be charged according to the first priority and the second priority.
After receiving the electric quantity information and the vehicle type of each vehicle to be charged sent by the reader-writer 102, the controller 103 determines a first priority of the vehicles to be charged according to the electric quantity information of the vehicles to be charged; and determining a second priority of the vehicle to be charged according to the vehicle type of the vehicle to be charged, and further determining the priority of the vehicle to be charged according to the first priority and the second priority.
A specific manner in which the controller 103 determines the first priority is described below.
In one embodiment, the power information includes remaining power and/or driving range. The remaining capacity represents the remaining capacity of the battery on the vehicle to be charged. The endurance mileage represents the mileage of the vehicle to be charged. When determining the first priority, the controller 103 determines the first priority of the vehicle to be charged according to the remaining capacity and the preset remaining capacity condition of the vehicle to be charged, and/or the mileage of the vehicle to be charged and the preset mileage condition.
Specifically, in an alternative embodiment, the controller 103 determines the first priority of the vehicle to be charged according to the remaining capacity of the vehicle to be charged and a preset remaining capacity condition. The preset residual capacity condition is a corresponding relation between a group of residual capacity intervals and the priority. The controller 103 compares the remaining capacity of the vehicle to be charged with the remaining capacity interval, and takes the priority corresponding to the remaining capacity interval in which the remaining capacity is located as the first priority.
For example, the preset remaining power condition may be: when the residual electric quantity is less than 10%, the corresponding priority is divided into 3 points; when the residual electric quantity is more than 10% and less than 30%, the corresponding priority is divided into 2 points; when the remaining capacity is greater than 50%, the corresponding priority is 1.
It can be understood that the above is only an example of a preset remaining power condition provided in the embodiment of the present application, and the embodiment of the present application does not specifically limit the specific values of the remaining power interval and the priority.
In another alternative embodiment, the controller 103 determines the first priority of the vehicle to be charged according to the mileage of the vehicle to be charged and the preset mileage condition. The preset endurance mileage condition is a corresponding relation between a set of endurance mileage thresholds and priority scores. The controller 103 compares the driving range of the vehicle to be charged with the driving range interval, and takes the priority corresponding to the driving range interval in which the driving range is located as the first priority.
For example, the preset endurance mileage condition may be: when the endurance mileage is less than 50 kilometers, the corresponding priority is divided into 3 points; when the residual electric quantity is more than 50 kilometers and less than 100 kilometers, the corresponding priority is divided into 2 points; when the remaining capacity is greater than 100 kilometers, the corresponding priority is 1.
It can be understood that the above is only an example of a preset remaining power condition provided in the embodiment of the present application, and the embodiment of the present application does not specifically limit the range and the specific value of the priority score.
In another alternative embodiment, the controller 103 determines the first priority of the vehicle to be charged according to the remaining capacity of the vehicle to be charged, and the preset remaining capacity condition, the driving range and the preset driving range condition.
It should be noted that, in consideration of the difference between the cruising ability of different vehicles and the remaining battery capacity, the controller 103 determines a priority score a according to the remaining battery capacity of the vehicle to be charged and the preset remaining battery capacity condition, determines a priority score B according to the cruising mileage and the preset cruising mileage condition, and takes the larger score of the priority score a and the priority score B as the first priority score of the vehicle to be charged.
For example, with the preset remaining power condition and the preset driving range condition in the above two examples as references, it is assumed that the remaining power of a certain vehicle to be charged is 20%, and the driving range is less than 50 km. In this case, the priority score a of the vehicle to be charged is 2, and the priority score B is 3. Since the driving range of the vehicle to be charged is less than 50 km, the vehicle to be charged is considered to be in urgent need of charging, and therefore, the priority score a and the priority score B with larger priority scores are taken as the first priority score (i.e. 3 scores) of the vehicle to be charged.
A specific manner in which the controller 103 determines the second priority is described below.
In one embodiment, the vehicle types of the vehicle to be charged include a commercial vehicle and an non-commercial vehicle, and the second priority score of the non-commercial vehicle is higher than the second priority score of the commercial vehicle. Wherein the non-utility vehicle may include: buses, fire trucks, ambulances, and the like.
In some embodiments, the second priority of civilian vehicles is a score of 1 and the second priority of non-civilian vehicles is a score of 3.
In other embodiments, the second priority of civilian vehicles is score 1, the second priority of buses is score 2, and the second priority of fire trucks and ambulances is score 3.
A specific manner in which the controller 103 determines the priority of the vehicle to be charged according to the first priority score and the second priority score will be described below.
The controller 103 determines a target priority of the vehicle to be charged according to the first priority and the second priority, and then determines the priority of the vehicle to be charged according to a correspondence between the preset priority and the target priority. The higher the target priority, the higher the corresponding priority.
In some embodiments, the correspondence between priority and target priority is as follows: setting 5 grades of priority, wherein the priority corresponding to the first grade of priority is divided into 6 grades, the priority corresponding to the second grade of priority is divided into 5 grades, and the like, and the priority corresponding to the fifth grade of priority is divided into 2 grades.
In other embodiments, the correspondence between priority and target priority is as follows: setting 3 as the priority, the priority corresponding to the first gear priority is divided into 5-6, the priority corresponding to the second gear priority is divided into 3-4, and the priority corresponding to the third gear priority is divided into 2.
It should be understood that the foregoing is only an example of the correspondence between the priority levels and the priority scores provided in the embodiment of the present application, and the correspondence between the priority levels and the priority scores is not specifically limited in the embodiment of the present application.
The controller 103 may determine the priority based on the first priority and the second priority in various manners.
In some embodiments, the first priority is added to the second priority to obtain a target priority for the vehicle to be charged.
In some embodiments, a first weight and a second weight are preset, the first priority is multiplied by the first weight, the second priority is multiplied by the second weight, and then the results of the two multiplications are added to obtain a target priority of the vehicle to be charged.
In the embodiment of the application, the first priority is determined according to the electric quantity information of the vehicle to be charged, and the second priority is determined according to the vehicle type of the vehicle to be charged. In order to meet the charging requirement of the non-civil vehicles preferentially, a larger second weight value can be set, and when the non-civil vehicles and the civil vehicles exist simultaneously, even if the first priority score of the non-civil vehicles is lower than that of the civil vehicles, under the action of the second weight value, the target priority score of the non-civil vehicles is larger than that of the civil vehicles, so that the priority score of the non-civil vehicles is higher than that of the civil vehicles, and charging piles are preferentially distributed for the non-civil vehicles.
The following describes a specific manner in which the controller 103 allocates charging piles according to the priority of each vehicle to be charged.
After the priority of each vehicle to be charged is determined, when it is determined that an idle charging pile exists in the current charging station, the controller 103 allocates the charging piles to each vehicle to be charged in sequence according to the sequence of the priorities of the priority.
Specifically, when determining that an idle charging pile exists in the current charging station, the controller 103 sends the charging pile information to the vehicle to be charged with the highest priority through the reader/writer 102. And after receiving confirmation information fed back by the vehicle to be charged with the highest priority, reducing the number of the idle charging piles by one. And then sending the charging pile information of the next idle charging pile to the vehicle to be charged with the next highest priority, and so on.
And if the confirmation information fed back by the vehicle to be charged with the highest priority is not received, sending the charging pile information to the vehicle to be charged with the second highest priority, and waiting for the confirmation information fed back by the vehicle to be charged with the second highest priority.
Further, in order to more efficiently distribute the charging piles, a preset time is set. And if the to-be-charged vehicle does not feed back the confirmation information within the preset time, pushing charging pile information to the vehicle with the next priority, and setting the to-be-charged vehicle which does not feed back the confirmation information at the tail of the to-be-charged vehicle queue waiting for charging at present. After pushing charging pile information to each vehicle to be charged in the vehicle queue to be charged waiting for charging at present, the charging pile information is pushed to the vehicle to be charged without feeding back confirmation information again.
The charging pile information may include a charging pile position, a charging pile number, a distance between the charging pile and the vehicle to be charged, and the like. In some embodiments, fill electric pile information and can send to the vehicle of waiting to charge with the form of map, the car owner can see directly perceivedly according to on-vehicle display screen and fill electric pile position to provide the navigation and guide the car owner and travel to filling electric pile.
Further, when the priorities of a plurality of vehicles to be charged are the same, the distances between the plurality of vehicles to be charged and the idle charging piles to be distributed are compared, and the charging piles are distributed to the vehicles to be charged which are closest to the charging piles.
It should be noted that the controller 103 may calculate a distance between the antenna 101 disposed on the charging pile and the electronic tag on the vehicle to be charged according to the signal strength of the electronic tag, so as to determine the distance between the charging pile and the vehicle to be charged.
