具体实施方式Detailed ways

请参见图1,一种基于共享充电桩的电动汽车智能充电方法,包括以下步骤:Please refer to Figure 1, a smart charging method for electric vehicles based on shared charging piles, including the following steps:

1、当电动汽车中锂电池电量降低到30%时,电动汽车发出提示音和/或在其显示屏上显示需要充电的内容进而提醒用户对其进行充电;1. When the power of the lithium battery in the electric vehicle is reduced to 30%, the electric vehicle will emit a prompt sound and/or display the content that needs to be charged on its display screen to remind the user to charge it;

30%是避免锂电池电量过低而导致的寿命损耗的下限,是针对锂电池而独特设置的,用户可以根据电动汽车发出的低电量的提示音和/或低电量的显示信息将电动汽车通过有线或无线的方式与充电桩连接;30% is the lower limit to avoid the life loss caused by the low battery power of the lithium battery. It is uniquely set for the lithium battery. The user can pass the electric car through the Connect to the charging pile in a wired or wireless way;

2、用户通过终端查找目的地附近的充电桩,并向每个目的地附近的充电桩发送充电预定请求以及电动汽车到达对应充电桩的时间、预估的到达时电动汽车锂电池电量;2. The user searches the charging piles near the destination through the terminal, and sends a charging reservation request to the charging piles near each destination, as well as the time when the electric vehicle arrives at the corresponding charging pile, and the estimated lithium battery power of the electric vehicle upon arrival;

终端可以为用户的移动终端,例如手机、平板电脑等,也可以是内嵌在电动汽车内的车载终端;在低电量报警的时候用户可能还需要使用电动汽车而不适合就地充电,因此,设置通过终端查找目的地,即用户想要将电动汽车停靠的地点;充电桩与目的地的距离可以由用户设定,例如查找以目的地为圆心,以5公里、10公里等为半径的范围内的充电桩;用户仅向目的地附近的充电桩发送充电预定请求,而非所有的充电桩,从而避免了不必要的大量通信信息的传输,降低了信息传输因为拥堵而可能导致的延迟、错误、甚至遗漏,进而提高了信息传输的可靠性;The terminal can be the user's mobile terminal, such as a mobile phone, tablet computer, etc., or a vehicle-mounted terminal embedded in the electric vehicle; when the low battery alarm occurs, the user may still need to use the electric vehicle and it is not suitable for on-site charging. Therefore, Set to find the destination through the terminal, that is, the place where the user wants to park the electric car; the distance between the charging pile and the destination can be set by the user, for example, search for a range with the destination as the center and a radius of 5 kilometers, 10 kilometers, etc. The charging piles within; the user only sends a charging reservation request to the charging piles near the destination, not all charging piles, thus avoiding unnecessary transmission of a large amount of communication information and reducing possible delays in information transmission due to congestion. Errors, or even omissions, thereby improving the reliability of information transmission;

3、每个目的地附近的充电桩接收充电预定请求以及对应的到达时间、预估的到达时电动汽车锂电池电量,并根据每个充电桩的工作情况以及被预定情况判断需要反馈的信息的内容;3. The charging pile near each destination receives the charging reservation request, the corresponding arrival time, and the estimated lithium battery power of the electric vehicle at the time of arrival, and judges the information that needs to be fed back according to the working conditions of each charging pile and the scheduled situation content;

如果充电桩处于工作状态,即充电桩正在为其他电动汽车充电,则充电桩根据该其他电动汽车的充电特性曲线判断将该其他电动汽车充满电还需要的时间Tother,如果Tother不大于到达时间Tarrive,则充电桩需要反馈的信息包括到达时可充电;如果Tother大于到达时间Tarrive,则充电桩需要反馈的信息包括到达后Tother-Tarrive可充电;If the charging pile is working, that is, the charging pile is charging other electric vehicles, the charging pile judges the time Tother needed to fully charge the other electric vehicles according to the charging characteristic curve of the other electric vehicles, if Tother is not greater than the arrival time Tarrive , the information that the charging pile needs to feed back includes that it can be charged when it arrives; if Tother is greater than the arrival time Tarrive, the information that the charging pile needs to feed back includes that Tother-Tarrive can be charged after arrival;

充电桩进一步判断是否存在其他电动汽车的充电预定信息,如果不存在,则充电桩需要反馈的信息包括可充电至满电;如果存在,则充电桩提取其他电动汽车的充电预定信息中的最早的充电预定时间Tset,并判断Tset是否不大于Tarrive,如果是则充电桩需要反馈的信息包括已满,不接受预定;如果Tset大于Tarrive,则充电桩根据预估的到达时电动汽车锂电池电量判断根据平均电动汽车的充电特性曲线将该电动汽车充满电需要的时间Tfull,并判断Tset是否不小于Tarrive+Tfull,如果是,则充电桩需要反馈的信息包括可充电至满电;如果Tset小于Tarrive+Tfull,则充电桩根据平均电动汽车的充电特性曲线判断该电动汽车充电Tset-Tarrive后能够达到的电量,此时充电桩需要反馈的信息包括预计可充电时间Tset-Tarrive以及预计能够达到的电量;The charging pile further judges whether there is charging schedule information of other electric vehicles. If not, the charging pile needs to feed back information including charging to full power; if it exists, the charging pile extracts the earliest charging schedule information of other electric vehicles. Charging scheduled time Tset, and judge whether Tset is not greater than Tarrive, if it is, the information that the charging pile needs to feed back includes that it is full and does not accept the reservation; if Tset is greater than Tarrive, the charging pile judges according to the estimated electric vehicle lithium battery power when it arrives According to the charging characteristic curve of the average electric vehicle, the time Tfull required to fully charge the electric vehicle, and judge whether Tset is not less than Tarrive+Tfull, if yes, the information that the charging pile needs to feed back includes charging to full power; if Tset is less than Tarrive +Tfull, the charging pile judges the amount of electricity that the electric vehicle can achieve after charging Tset-Tarrive according to the charging characteristic curve of the average electric vehicle. At this time, the information that the charging pile needs to feed back includes the expected charging time Tset-Tarrive and the expected amount of electricity ;

到达时间的设置使得充分考虑了能够给低电量的电动汽车充电的充电桩,尤其是那些虽然正在被使用但是很快即可用的充电桩;提供预估的到达时电动汽车锂电池电量能够使得低电量的电动汽车可以被短时的充电,例如在预定的其他电动汽车还没来进行充电的时候,可以立刻弥补电动汽车的低电量状态,由于长期处于低电量状态将会使得锂电池损毁,因此,这种设置不仅能够延长电动汽车中锂电池的使用寿命,还能在需要紧急续航使用时提供便利;The setting of the arrival time makes it possible to fully consider the charging piles that can charge electric vehicles with low power, especially those charging piles that are being used but will be available soon; Electric vehicles with high battery capacity can be charged for a short time. For example, when other scheduled electric vehicles have not come to charge, it can immediately make up for the low battery state of the electric vehicle. Because the lithium battery will be damaged if it is in a low battery state for a long time, so , this setting can not only prolong the service life of lithium batteries in electric vehicles, but also provide convenience when emergency battery life is required;

4、每个目的地附近的充电桩根据需要反馈的信息的内容,将处理后的信息发送给终端;4. The charging pile near each destination sends the processed information to the terminal according to the content of the information that needs to be fed back;

当需要反馈的信息的内容包括已满,不接受预定时,充电桩仅反馈已满,不接受预定的信息给终端;When the content of the information that needs to be fed back includes that it is full and does not accept reservations, the charging pile only feeds back the information that it is full and does not accept reservations to the terminal;

当需要反馈的信息的内容不包括已满,不接受预定时,充电桩反馈所有需要反馈的信息给终端;When the content of the information that needs to be fed back does not include that it is full and the reservation is not accepted, the charging pile will feed back all the information that needs to be fed back to the terminal;

即使存在需要等待才能充电的情况以及充电时间很短的情况也发送给用户,用户可以基于自身的特定情况进行选择和考虑;Even if there is a need to wait for charging and the charging time is very short, it will be sent to the user, and the user can choose and consider based on his own specific situation;

5、终端接收充电桩发送的信息并显示在其显示屏上,用户根据显示内容在终端上选择合适的充电桩,终端发送确认预定信息给合适的充电桩,充电桩在接收到确认预定信息后反馈已预定信息给终端并显示在显示屏上,用户驾驶电动汽车前往反馈已预定信息的充电桩,用户驾驶电动汽车前往反馈已预定信息的充电桩。5. The terminal receives the information sent by the charging pile and displays it on its display screen. The user selects the appropriate charging pile on the terminal according to the displayed content, and the terminal sends confirmation reservation information to the appropriate charging pile. After receiving the confirmation reservation information, the charging pile The scheduled information is fed back to the terminal and displayed on the display screen. The user drives the electric car to the charging pile that feeds back the scheduled information, and the user drives the electric car to the charging pile that feeds back the scheduled information.
