背景技术Background technique
随着人们对环境保护意识的增强，电动汽车因其无污染的优势，越来越深入人们的生活。在电动汽车使用的过程中，电动汽车用户需要在汽车电能将要耗尽的时候选择到固定地点的充电站，利用充电站中的充站桩为汽车的电池进行直接充电。With the enhancement of people's awareness of environmental protection, electric vehicles have become more and more popular in people's lives because of their advantages of no pollution. During the use of electric vehicles, electric vehicle users need to choose a charging station at a fixed location when the electric energy of the vehicle is about to run out, and use the charging piles in the charging station to directly charge the battery of the vehicle.
为何方便电动汽车用户快速找到充电站，目前有些城市制作了充电站分布地图，如北京市发布的电动汽车社会公用充电设施分布图，电动车用户可通过网站、手机APP、微信等方式查找附近的充电设施信息，包括充电站的具体位置、充电桩数量、充电桩空闲数等，方便电动车用户查找最近的充电桩进行“出行补电”。Why is it convenient for electric vehicle users to quickly find charging stations? At present, some cities have produced distribution maps of charging stations, such as the distribution map of electric vehicle social public charging facilities released by Beijing. Electric vehicle users can find nearby charging stations through websites, mobile apps, and WeChat. Charging facility information, including the specific location of the charging station, the number of charging piles, the number of idle charging piles, etc., is convenient for electric vehicle users to find the nearest charging pile for "travel recharging".
上述充电站分布地图为电动车充电提供了便利，但是在电动车用户使用所述分布地图的时候也常常遇到如下情况：The above distribution map of charging stations provides convenience for electric vehicle charging, but when electric vehicle users use the distribution map, they often encounter the following situations:
当赶往最近的充电桩为电动车进行充电的时，发现查询到的空闲充电桩已经被他人使用，此时电动车用户不得不寻找其他充电桩，或者等待他人充电完毕。When rushing to the nearest charging pile to charge the electric vehicle, it is found that the queried idle charging pile has been used by others. At this time, the electric vehicle user has to look for other charging piles, or wait for others to finish charging.
