Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The first embodiment of the invention provides a self-service charging method for an electrically driven vehicle, wherein an execution main body of the self-service charging method is a control module of the vehicle, and the vehicle control module can be front-mounted equipment of the vehicle or rear-mounted equipment of the vehicle, and is integrated with functions for controlling the vehicle to perform self-service charging, such as a vehicle terminal, an intelligent terminal and the like. Fig. 1 is a schematic flow chart of a self-service charging method for an electrically driven vehicle according to a first embodiment of the present invention, as shown in fig. 1, the method mainly includes the following steps:
and 101, setting an electric quantity early warning threshold of the electric quantity of a vehicle battery, or generating the electric quantity early warning threshold of the current day according to the external temperature.
Specifically, an electric quantity early-warning threshold of the electric quantity of the battery of the vehicle is set, or the electric quantity early-warning threshold of the current day is generated according to the external temperature, so that when the residual electric quantity reaches the electric quantity early-warning threshold, the vehicle is reminded to carry out charging operation, and the situation that the electric quantity is exhausted and cannot run is avoided. The electric quantity early warning threshold value is set by considering the distribution condition of charging stations on the vehicle driving route and the historical power consumption information of the vehicle. In addition, since the battery capacity of the electric vehicle is greatly affected by the ambient temperature, the optimal running environment of the electric vehicle is about 25 ℃ of air temperature, when the temperature is reduced, the battery capacity is also obviously reduced, when the air temperature is 0 ℃, the battery capacity is approximately equal to about 70% of normal, when the air temperature is 1 ℃ below zero, the battery capacity is approximately reduced by 1%, and when the air temperature is lower, the running mileage of the electric vehicle is correspondingly shortened, so that the setting of the electric quantity early warning threshold value should take the ambient temperature into consideration, and the electric quantity early warning threshold value on the current day is generated according to the ambient temperature. Meanwhile, the service life of the battery is influenced by overdischarge, so that the electric quantity early warning threshold value is preferably not lower than 30% of the total electric quantity as much as possible. The electrically drivable vehicle in this embodiment is specifically an electric vehicle, a hybrid electric vehicle or an extended range vehicle.
When the vehicle is running, judging whether the network between the vehicle and the cloud server is smooth or not when the residual electric quantity reaches an electric quantity early warning threshold value, executing step 102 when the network is interrupted, and executing steps 103 and 104 when the network is smooth.
And 102, when the network is interrupted and the residual electric quantity reaches an electric quantity early warning threshold value, calling locally stored charging station information.
Specifically, when the remaining electric quantity of the vehicle reaches a set electric quantity early warning threshold, the vehicle tries to send charging request information to the cloud server, and when the network is interrupted, the vehicle cannot get in touch with the cloud server, and at this time, the vehicle invokes locally stored charging station information. The locally stored charging station information is charging station information stored in the vehicle in advance, has certain hysteresis, and is used only when the network is interrupted and the cloud server cannot be connected. Step 105 is performed after invoking the locally stored charging station information.
And step 103, when the network is smooth and the residual electric quantity reaches an electric quantity early warning threshold value, sending charging request information to the cloud server.
Specifically, when the network between the vehicle and the cloud server is smooth and the remaining battery capacity of the vehicle reaches an electric quantity early warning threshold, the vehicle generates charging request information, sends the charging request information to the cloud server, and waits for the cloud server to return corresponding charging station information. The charging request information includes a vehicle ID and current electric quantity information of the vehicle. The vehicle ID is used to identify the identity of the vehicle and the current charge information of the vehicle is used to calculate the remaining range of the vehicle.
And 104, receiving charging station information which is returned by the cloud server and is generated according to the charging request information.
Specifically, after the vehicle sends the charging request information to the cloud server, the cloud server generates corresponding charging station information according to the charging request information, wherein the charging station information is stored at the cloud server, and the charging station information is updated at regular time by the cloud server to ensure the timely and accurate information. The cloud server obtains information of a plurality of charging stations which are suitable according to the position information of the vehicle in the charging request information sent by the vehicle, generates charging station information and returns the charging station information to the vehicle.
Further, if the vehicle does not receive charging station information returned by the cloud server within the first time threshold, the charging request information is sent to the cloud server again. That is, after the vehicle sends the charging request information to the cloud server, the vehicle does not receive the charging station information fed back from the cloud server within the first time threshold due to poor communication and other reasons, and at this time, the vehicle sends the charging request information to the cloud server again.
Still further, if the vehicle still does not receive the charging station information fed back by the cloud server within the second time threshold, the vehicle does not wait for the return result of the cloud server, but invokes charging station information stored in advance locally by the vehicle, wherein the second time threshold is larger than the first time threshold, and the charging station information comprises position information of a plurality of charging stations.
Specifically, after locally stored charging station information is called or charging station information sent by a cloud server is received, the charging station information is analyzed, and position information of a plurality of charging stations is obtained.
Further, when the network is smooth and the charging station information is charging station information acquired from the cloud server, the charging station information not only comprises the position information of a plurality of charging stations, but also comprises the current charging busyness information of each charging station, and the charging busyness information is used for indicating the busyness state of the charging station for charging the vehicle currently, so that a reference basis can be provided for the vehicle when the charging station is selected.
And 106, calculating distance data of the charging stations according to the position information of the charging stations, obtaining a priority order of the charging stations according to the running direction of the vehicle, the position information of the charging stations and the distance data, and selecting the charging station with the highest priority as the target charging station.
Specifically, distance data between each charging station and the vehicle is sequentially calculated according to the analyzed position information of the plurality of charging stations, and the priority of the charging stations is set according to the running direction of the vehicle, the position information of the charging stations and the distance data, so that the priority order of the charging stations is obtained. The priority setting of the charging stations is specifically based on distance data between the vehicle and the charging stations, the priority of the charging stations with the closer distance is higher, meanwhile, the position information and the vehicle running direction of the charging stations are considered, the priority of the charging stations with the position information in the vehicle running direction is higher, the priority of the position information deviating from the vehicle running direction is lower, the deviation angle is larger, the priority is lower, and the priority of the charging stations deviating from the vehicle running direction is lowest. And selecting the charging station with the highest priority from the obtained charging station priority sequence as the target charging station.
Further, when charging station information includes current charging busyness information of each charging station, the method further includes:
and acquiring the priority order of the charging stations according to the charging busyness information, wherein the charging stations with lower busyness have higher priority.
Specifically, the priority of each charging station is set according to the charging busyness information of the charging station, and the priority order of the charging stations based on the charging busyness information is obtained, wherein the lower the busyness is, the fewer vehicles the charging station is currently charging or is about to charge, the charging station can provide charging service for the vehicles as soon as possible, and therefore, the higher the priority order of the charging stations is.
Specifically, after the target charging station is determined, a travel path is planned according to the position of the target charging station, and the vehicle travels to the target charging station according to the travel path. After reaching the target charging station, the vehicle establishes communication connection with the target charging station, informs the target charging station that the vehicle has arrived, and performs mutual identity verification with the target charging station to establish a session channel.
Specifically, after the vehicle arrives at the target charging station and establishes a session with the target charging station, the vehicle sends a charging station request to the target charging station and waits for the target charging station to allocate an available charging peg for the target charging station. The charging pile request includes a charging type that the vehicle wants to use, for example: and the charging requirements of different types such as fast charging, slow charging or wireless charging are met.
Specifically, the target charging station distributes corresponding charging piles for the vehicle according to a charging pile request sent by the vehicle, sends charging pile information to the vehicle, and sends in-station map information of the target charging station to the vehicle at the same time, and after receiving the charging pile information and in-station map information returned by the target charging station, the vehicle performs path planning according to the position information of the charging piles and the in-station map information contained in the charging pile information to generate an in-station driving path; and the vehicle runs in the target charging station according to the generated in-station running path and is parked on the charging pile position corresponding to the charging pile information. After the charging stake position of the vehicle is stopped, the information that the vehicle is completely parked is sent to the target charging station, and the target charging station waits for the charging station to carry out charging service.
Specifically, after receiving the message that the vehicle is parked at the charging stake position, the target charging station sends a charging start instruction to the vehicle, and after receiving the charging start instruction sent by the target charging station, the vehicle opens a charging port of the vehicle and starts to receive electric energy. Meanwhile, in the process of receiving the charging service, the vehicle can also feed back the electric quantity information of the vehicle battery to the target charging station in real time.
Specifically, after the battery of the vehicle is fully charged, the target charging station stores the charging equipment, sends a charging completion instruction to the vehicle, and closes the charging port after the vehicle receives the charging completion instruction sent by the target charging station.
The second embodiment of the invention provides a self-service charging device for an electrically-driven vehicle, which is a device capable of realizing the self-service charging method for the electrically-driven vehicle.
