The invention discloses a pure electric vehicle charging path planning navigation method and system, and the method comprises the steps: S101, judging whether the current electric quantity meets the long-distance travel or not according to the destination information, the departure place information, the historical average power consumption of a vehicle, the vehicle-mounted navigation map information, the vehicle-mounted navigation charging pile distribution information, and the remaining electric quantity of the vehicle; if so, providing a path and a charging plan along the way, otherwise, reminding charging; s102, in the driving process of the vehicle according to the planned path, real-time electric quantity consumption of the vehicle is obtained, whether the vehicle can reach the next planned charging pile or not is judged, and if not, it is reminded that the real-time electric quantity consumption exceeds the plan; s103, searching whether a charging pile exists in the remaining endurance mileage range or not, and if the charging pile exists, providing countermeasures for selection according to an implementation strategy: 1, changing a path and a charging plan along the way; 2, forcing the vehicle to adopt pre-configured power consumption reduction measures; otherwise, forcing the vehicle to take a second response measure. The actual demand of charging planning of the driver is met.

    本发明公开了一种纯电动汽车充电路径规划导航方法及系统,该方法包括:S101、根据目的地信息、出发地信息、车辆历史平均电耗、车载导航地图信息、车载导航充电桩分布信息、车辆剩余电量来判断当前电量是否满足长途出行,若是则提供路径及沿途充电规划,否则提醒充电;S102、在车辆按照规划的路径行驶过程中,获取车辆的实时电量消耗,判断该车辆是否可以到达规划的下一个充电桩,否则提醒实时电量消耗超出规划;S103、查找剩余续航里程范围内是否有充电桩,若有充电桩则根据实施策略提供应对措施供选择:一、更改路径及沿途充电规划;二、强制车辆采用预先配置的电耗降低措施;否则强制车辆采用应对措施二。本发明满足了驾驶员充电规划的实际需求。
