Referring to fig. 1, fig. 1 is a schematic flow chart illustrating an electric vehicle charging early warning method according to an embodiment of the present application. The electric vehicle charging early warning method comprises the following steps:

And S102, estimating the power consumption according to the driving habit, the target position and the road congestion coefficient of the driver.
S103, judging whether the target position can be reached or not according to the current vehicle residual electric quantity and the current power consumption, and if so, ending the process; if not, go to step S104.
In the embodiment, the method can compare the electric quantity which is estimated to be consumed along the way by the vehicle control system with the current electric quantity according to the habit of a driver after the destination is selected, and judge whether the destination and the nearby charging pile can be reached or not by the vehicle system after the historical congestion coefficient of the road is increased. If yes, no prompt is needed; if not, the missing charge and the charge request need to be sent to the navigation system (i.e., subsequent steps).
And S104, calculating the required electric quantity to be charged according to the current vehicle residual electric quantity and the current power consumption.
And S105, outputting the charging early warning information comprising the required electric quantity.
S106, when a charging instruction is received, determining a charging requirement; wherein the charging requirements include a required voltage platform, charging power, charging current, and vehicle positioning information.
And S107, determining nearby charging stations according to the vehicle positioning information.

And S111, outputting the position information of the target charging pile on the navigation map.
In this embodiment, the method may forward the charging request to a nearby charging station through the background, including signals of a required voltage platform, charging power, charging current, vehicle positioning, and the like. After receiving a charging request, the charging station firstly swipes appropriate charging piles inside the vehicle, mainly based on the principle of proximity, and sends a plurality of idle charging piles which are closest to the vehicle and can meet the basic charging requirement of the vehicle and the position which completely meets the charging capacity requirement of the vehicle to a navigation system for a driver to select.
And S112, marking the position information and the charging pile information of the target charging pile on the navigation map.
And S113, determining the most preferable charging pile and the common charging pile from the target charging piles according to preset optimal selection conditions.
And S114, marking the most preferable charging pile and the common charging pile in different colors on the navigation map.
In this embodiment, the charging station in the method can send the matched charging pile information to the navigation platform through the background; the navigation platform lights the charging pile position in the map after receiving the information, displays the information related to the charging pile, and distinguishes the optimal charging pile and the common charging pile which meet the requirements by using colors.
And S115, determining a selected charging pile selected by the driver from the target charging piles.
And S116, acquiring the position information of the selected charging pile and the current real-time road condition.
And S117, determining at least one navigation path according to the current real-time road condition and the position information of the selected charging pile.
And S118, receiving a selected path selected by the driver from the navigation paths.
And S119, outputting navigation prompt information according to the selected path.
S120, judging whether the selected charging pile is occupied or not, and if so, executing a step S121; if not, the flow is ended.
In this embodiment, this step is performed during traveling according to the navigation guidance information.
And S121, outputting occupied prompt information of the selected charging pile, and outputting prompt information of reselecting the charging pile.
In the embodiment, after the driver can select the charging pile position needing to go to the screen, the navigation provides a proper path for the driver to select according to the real-time road condition, the jammed road section is staggered as much as possible, and the driver is reminded and prompted whether to reselect the optimal charging position or not if the charging position is occupied during driving.
In this embodiment, the internal estimation system of the vehicle includes the daily driving habit of the driver, the power consumption of the external and internal electrical devices of the vehicle, the daily power consumption, the power consumption of the air conditioner, and the like. Therefore, the method can estimate the total power consumption of the vehicle and compare the current discharging condition of the vehicle with the current state of the vehicle battery pack to judge whether the current state of the vehicle can reach the destination.
In this embodiment, the background signal receiving device of the charging station and the internal screening system thereof may perform the next screening after receiving the charging request of the vehicle, and then select the voltage platform matched with the vehicle through the internal screening of the charging station.
In this embodiment, the road section screening function of the navigation system can make the place clear, and then the accurate navigation system can quickly reach the destination, so that the time cost is greatly saved.
In the embodiment, the method can also be applied to the electric bicycle; meanwhile, the method logic is also applicable to some search engines, such as the process of screening from price, production area, quality, beauty and goodness.
In this embodiment, the execution subject of the method may be a computing device such as a computer and a server, and is not limited in this embodiment.
In this embodiment, the main body of the method may also be an intelligent device such as a smart phone and a tablet computer, which is not limited in this embodiment.
It can be seen that, by implementing the electric vehicle charging early warning method described in this embodiment, whether the current state of the electric vehicle can safely reach the destination can be clearly known according to the estimation of the vehicle internal system. Meanwhile, after estimation, the driver can be warned in advance to supplement power, and accidents caused by anchor dropping in the driving process are avoided. Meanwhile, the method can also clearly know the position of the charging pile meeting the charging requirement of the vehicle through the internal data screening of the charging station, so that the situation that the charging pile is found everywhere and is not necessarily suitable after the charging pile is found is avoided, and more time is saved for a driver. In addition, the method can also provide the most appropriate driving route for the driver quickly through the statistics and screening of the navigation system, so that the time and the electric quantity are saved, and the phenomena of traffic jam and the like are avoided. Finally, the method can constantly estimate whether the current state of the vehicle can reach the selected charging pile position through a vehicle internal system, and can effectively avoid the phenomenon of anchoring due to insufficient electric quantity on the way to the charging pile; moreover, the occupation condition of the charging pile is known in advance by monitoring the state of the charging pile in real time, so that a driver can plan a route in advance and avoid waiting for charging in a queue.
