Fig. 1 is a flowchart of an electric vehicle intelligent charging method based on a shared charging pile.
Detailed Description
Referring to fig. 1, an electric vehicle intelligent charging method based on a shared charging pile includes the following steps:
1. when the electric quantity of a lithium battery in the electric automobile is reduced to 30%, the electric automobile gives out prompt tone and/or displays the content needing to be charged on a display screen of the electric automobile so as to remind a user of charging the electric automobile;
30% is the lower limit of life loss caused by avoiding the over-low electric quantity of the lithium battery, and is uniquely set for the lithium battery, so that a user can connect the electric automobile with the charging pile in a wired or wireless mode according to the low-electric-quantity prompt tone and/or the low-electric-quantity display information sent by the electric automobile;
2. a user searches charging piles near destinations through a terminal, and sends a charging reservation request, the time of the electric automobile reaching the corresponding charging pile and the estimated electric quantity of a lithium battery of the electric automobile when the electric automobile reaches the corresponding charging pile to the charging piles near each destination;
the terminal can be a mobile terminal of a user, such as a mobile phone, a tablet personal computer and the like, and can also be a vehicle-mounted terminal embedded in an electric automobile; when the low-power alarm is performed, the user may need to use the electric automobile and is not suitable for charging on the spot, so that the user can find the destination through the terminal, namely, the place where the user wants to stop the electric automobile; the distance between the charging pile and the destination can be set by a user, for example, the charging pile which takes the destination as the center of a circle and takes 5 kilometers, 10 kilometers and the like as the radius is searched; the user only sends a charging reservation request to the charging piles near the destination instead of all the charging piles, so that unnecessary transmission of a large amount of communication information is avoided, delay, errors and even omission caused by congestion of information transmission are reduced, and reliability of information transmission is improved;
3. the charging pile near each destination receives a charging reservation request, corresponding arrival time and estimated electric quantity of a lithium battery of the electric automobile at the arrival time, and judges the content of information needing to be fed back according to the working condition and the reserved condition of each charging pile;
if the charging pile is in a working state, namely the charging pile is charging other electric vehicles, the charging pile judges the time Tother still needed for fully charging the other electric vehicles according to the charging characteristic curves of the other electric vehicles, and if the Tother is not more than the arrival time Tarrive, the information needing to be fed back by the charging pile comprises charging when the electric vehicles arrive; if the Tother is greater than the arrival time Tarrive, the information required to be fed back by the charging pile comprises that the Tother-Tarrive can be charged after the arrival;
the charging pile further judges whether charging preset information of other electric vehicles exists or not, and if the charging preset information does not exist, the information needing to be fed back by the charging pile comprises chargeable to full charge; if the charging schedule information exists, the charging pile extracts the earliest charging schedule Tset in the charging schedule information of other electric vehicles and judges whether the Tset is not greater than Tarrive, and if the Tset is not greater than Tarrive, the information needing to be fed back by the charging pile comprises fullness and does not accept the schedule; if the Tset is greater than Tarrive, the charging pile judges the time Tful required by fully charging the electric automobile according to the estimated electric quantity of the lithium battery of the electric automobile when the electric automobile arrives, judges whether the Tset is not less than Tarrive + Tful or not, and if the Tset is not less than Tarrive + Tful, the information required to be fed back by the charging pile comprises chargeable to full charge; if the Tset is smaller than Tarrive + Tful, the charging pile judges the electric quantity which can be reached by the electric automobile after charging the Tset-Tarrive according to the average charging characteristic curve of the electric automobile, and the information which needs to be fed back by the charging pile at the moment comprises the predicted chargeable time Tset-Tarrive and the predicted electric quantity which can be reached;
the setting of the arrival time makes full consideration of charging piles capable of charging low-battery electric vehicles, particularly those which are used but are available soon after use; the estimated electric quantity of the lithium battery of the electric automobile at the arrival can enable the electric automobile with low electric quantity to be charged in a short time, for example, when other preset electric automobiles are not charged, the low electric quantity state of the electric automobile can be immediately made up, and the lithium battery can be damaged due to long-term low electric quantity state, so that the arrangement not only can prolong the service life of the lithium battery in the electric automobile, but also can provide convenience when the electric automobile needs to be used in an emergency journey;
4. the charging pile near each destination sends the processed information to the terminal according to the content of the information fed back by the charging pile as required;
when the content of the information needing to be fed back comprises full information and does not accept reservation, the charging pile only feeds back the full information and does not accept the reservation information to the terminal;
when the content of the information needing to be fed back does not include the full content and does not accept the reservation, the charging pile feeds back all the information needing to be fed back to the terminal;
even if the situation that the user needs to wait for charging and the situation that the charging time is short exist, the charging time is sent to the user, and the user can select and consider the charging time according to the specific situation of the user;
5. the terminal receives information sent by the charging piles and displays the information on a display screen of the terminal, a user selects a proper charging pile on the terminal according to display content, the terminal sends confirmation preset information to the proper charging pile, the charging pile feeds back the preset information to the terminal after receiving the confirmation preset information and displays the preset information on the display screen, the user drives the electric automobile to go to the charging pile feeding back the preset information, and the user drives the electric automobile to go to the charging pile feeding back the preset information.
It should be noted that the above-mentioned embodiments are provided for further detailed description of the present invention, and the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make various modifications and variations on the above-mentioned embodiments without departing from the scope of the present invention.
