Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features in the embodiments may be combined with each other without collision.
In addition, the terms "first," "second," "third," etc. in the terms of embodiments of the present invention are used to distinguish similar objects from each other, and are not necessarily used to describe a specific number or order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely illustrative of the manner in which embodiments of the invention have been described in connection with objects of the same nature. The vehicle according to the embodiment of the invention may be a hybrid vehicle using an engine and an electric motor as power sources, an electric vehicle using an electric motor as a power source, or the like.
Fig. 1 is a schematic diagram of main steps of a charging station recommendation method according to an embodiment of the present invention. As shown in fig. 1, the charging station recommendation method may mainly include the following steps S101 to S104:
Step S101: a recommendation request of the charging station is obtained, wherein the recommendation request indicates a target position of a user. The user can be the owner of the vehicle or other users authorized by the vehicle owner. The recommendation request may be initiated before the vehicle is used, for example, the user may initiate a reservation request through the user terminal before the vehicle is used, where the reservation request may carry the location and time that the user wants to charge, so as to initiate the recommendation request of the charging station to the vehicle-mounted server. In addition, the time for initiating the recommendation request can also be in the process of using the vehicle, for example, the user initiates the recommendation request of the charging station through the central control display screen or the voice command in the process of using the vehicle, and in this case, the target position indicated by the recommendation request is the current position of the user, namely, the current position of the vehicle.
Step S102: one or more selectable charging stations are determined based on the target location.
If the recommendation request initiated by the user is a reservation request before the user uses the vehicle, one or more selectable charging stations corresponding to the target position can be determined according to the position where the user wants to charge and the preset distance carried in the reservation request. If the preset distance is 1km, the target position carried in the reservation request is taken as the circle center, and the optional charging station is searched in the circumference range with the radius of lkm.
If the user initiates the recommendation request in the vehicle using process, the current position of the vehicle can be determined according to the positioning information acquired by the vehicle-mounted GPS, the running range of the vehicle is determined by combining the current residual electric quantity of the vehicle, and one or more optional charging stations are determined in the running range, so that the situation that the user cannot run to the optional charging stations due to the fact that the residual electric quantity is small but the determined optional charging stations are far can be avoided, and the charging success rate is improved. Of course, when a recommendation request is initiated in the vehicle using process, the vehicle-mounted controller can also adopt a mode of directly searching for the optional charging station according to the preset distance in the reservation process.
The preset distance may correspond to a low battery alert mechanism. For example, the vehicle-mounted controller is configured to send out a low power prompt message when the power is lower than 10%, and the driving distance corresponding to the 10% power is 5km, so that the preset distance can be set to be 5km. The user is likely to initiate the recommendation request of the charging station immediately after learning the low-power prompt information, so that the preset distance is set to correspond to the low-power prompt mechanism, and the charging station in the driving range is recommended to the user, and the charging success rate is improved.
Step S103: the charge failure rate of the one or more selectable charging stations and the first charging stake type are determined separately.
In the embodiment of the present invention, for each of the selectable charging stations, it is possible to perform: determining one or more charging tasks corresponding to the selectable charging stations and an execution result of each charging task; determining the execution result as a target charging task with charging failure; and determining the charging failure rate of the selectable charging stations according to the number of the target charging tasks and the total number of the charging tasks of the selectable charging stations. For example, one or more charging tasks corresponding to the selectable charging stations may be determined by a charging order in the background, which may include tasks that have ended charging and tasks that are charging. When determining the target charging tasks with failed charging, any one or more of charging duration, charging interruption signal, charging current and charging voltage corresponding to each charging task can be obtained, and the execution result of the charging tasks can be determined according to any one or more of the charging duration, the charging interruption signal, the charging current and the charging voltage.
For example, if the charging duration of the charging task is greater than a preset time threshold, that is, the charging time is too long, and the number of the charging interruption signals is greater than a preset number threshold, that is, a situation that a plurality of signal interruption occurs in the charging process, the charging current does not belong to a preset current interval, the charging current is too large or too small, or the charging voltage does not belong to a preset voltage interval, and the charging voltage is too large or too small, the charging failure of the charging task is determined. That is, if any one of the charging time is too long, the signal is interrupted for a plurality of times, the charging current is too large or too small, and the charging voltage is too large or too small occurs in the charging process, it may be determined that the charging task is not normally ended, that is, the charging task fails. The charging failure rate of an optional charging station may then be determined based on the ratio between the number of target charging tasks that failed to charge and the total number of all charging tasks for that optional charging station. Therefore, the charging station is conveniently recommended to the user by combining the charging failure rate, the user is prevented from being recommended to the charging station with higher failure rate, the charging success rate is improved, and in addition, vehicle enterprises can conduct failure reason investigation and maintenance on each charging station by utilizing the information, so that the maintenance of the charging station is facilitated.
It should also be appreciated that a plurality of charging posts are provided in the charging station, which may be different types of charging posts, such as alternating current charging posts and direct current charging posts. In order to avoid a situation that a user recommends that a charging pile type is not matched with a vehicle and thus a charging failure occurs, in the embodiment of the invention, besides determining the charging failure rate, the charging pile type of the charging station can also be determined, so that a target charging station is recommended for the user by combining the charging failure rate and the charging pile type.
Step S104: and determining a target charging station from the one or more selectable charging stations according to the charging failure rate and the first charging pile type, and recommending the target charging station to a user.
In this embodiment, a second charging pile type matched with the host vehicle and a charging pile in an idle state in the one or more optional charging stations may be determined, and an optional charging station in which the first charging type of the charging pile is matched with the second charging pile type corresponding to the host vehicle and the charging failure rate of the optional charging station to which the charging pile belongs is smaller than a preset threshold value may be determined as the target charging station. Therefore, the type of the hollow charging pile recommended to the user in the target charging station is matched with the vehicle, and the charging failure rate is smaller than a preset threshold, so that the charging success rate of the user is improved.
In a preferred embodiment of the present invention, if there are a plurality of target charging stations that match the charging type of the host vehicle and have a charging failure rate smaller than a preset threshold, the number of charging piles that match the host vehicle in the target charging stations may be determined, and the plurality of target charging stations may be ranked according to the distance between the host vehicle and the target charging stations, the number of charging piles, and the charging failure rate; and recommending the plurality of target charging stations to the user according to the sorting result. For example, the type of the charging piles required by the vehicle is alternating current, 5 alternating current charging piles are in an idle state in the target charging station A, the charging failure rate of the target charging pile A is 10%, and the distance between the charging piles and the vehicle is 500m; there are 8 ac charging piles in an idle state in the target charging station B, and the charging failure rate of the target charging station B is 8%, and the distance between the target charging station B and the host vehicle is 300m. When sorting the target charging station A and the target charging station B, different weight values can be set in advance for the distance between the vehicle and the target charging station, the number of charging piles which are matched with the vehicle type and are in an idle state in the charging station and the charging failure rate, and then sorting is carried out according to the preset weight values and the determined specific parameters of the target charging station A and the target charging station B. In this example, the target charging station B may be arranged before the target charging station a, thereby facilitating the user's selection of a target charging station that may facilitate successful charging.
The charging station recommendation method provided by the embodiment of the invention is further described below by taking a recommendation request of a charging station initiated by a user in a vehicle-using process as an example. As shown in fig. 2, the charging station recommendation method may include the steps of:
step S201: and acquiring a recommendation request of the charging station, and acquiring GPS data according to the recommendation request to determine the current position of the user.
Step S202: a drivable range of the vehicle is determined based on the current position and the remaining amount of the vehicle, one or more optional charging stations are determined within the drivable range, and the following steps S203 to S205 and S206 to S207 are performed for each of the optional charging stations.
The execution sequence of step S203 and step S206 is not limited, that is, step S20 may be executed first, and then step S206 may be executed; step S206 may be performed first, and then step S203 may be performed; or step S203 and step S206 may be performed simultaneously.
Step S203: and determining one or more charging tasks corresponding to the selectable charging stations, and acquiring charging duration, a charging interruption signal, charging current and charging voltage corresponding to each charging task.
Step S204: and determining the charging task with the charging duration time being larger than a preset time threshold value, the number of the charging interruption signals being larger than a preset number threshold value, the charging current not belonging to a preset current interval or the charging voltage not belonging to a preset voltage interval as a target charging task with the charging failure.
Step S205: and determining the charging failure rate of the selectable charging stations according to the number of target charging tasks and the total number of charging tasks of the selectable charging stations.
Step S206: a charging stake in an idle state in the selectable charging stations and a first charging stake type of the charging stake are determined.
Step S207: judging whether the first charging pile type is matched with a second charging pile type required by the vehicle; if yes, step S208 is executed, otherwise, the determination is continued for the next optional charging station until all the optional charging stations are executed.
Step S208: and determining the charging failure rate of the selectable charging station, and determining the selectable charging station as a target charging station in the case that the charging failure rate is smaller than a preset threshold.
Step S209: and sequencing the target charging stations according to the number of charging piles matched with the vehicle in the target charging stations, the distance between the vehicle and the target charging stations and the charging failure rate, and recommending the target charging stations for the users according to the sequencing result.
According to the method for recommending the charging stations, after the recommendation request of the charging stations is obtained, the selectable charging stations can be determined according to the target positions indicated by the recommendation request, and then the target charging stations are determined from the selectable charging stations by combining the charging failure rates and the types of the charging piles of the selectable charging stations, and are recommended to the users. Because the target charging station recommended to the user is obtained by combining the target position of the user, the charging failure rate of the charging station and the charging pile type of the charging station, the target charging station can be matched with the vehicle, thereby being beneficial to avoiding the situation of too slow charging or interrupted charging and improving the charging efficiency.
