The invention relates to an electric vehicle charging reminding method and system, an electric vehicle and a storage medium. The method comprises the steps that under the condition that it is detected that the electric vehicle is in a parking state, according to current positioning data and historical driving data of the electric vehicle and temperature information within a preset duration, the predicted battery temperature of the electric vehicle after parking is finished during next starting and using is determined, the predicted battery temperature refers to the battery temperature of the cooled battery after the electric vehicle is parked for a period of time, and the corresponding target battery available capacity is determined according to the predicted battery temperature, that is, in combination with the influence of temperature change on the battery capacity of the electric vehicle, under the condition that the endurance mileage corresponding to the target battery available capacity is smaller than the target mileage, the battery capacity of the electric vehicle is determined. If yes, the available capacity of the target battery is not enough to support the electric vehicle to drive to the target charging station when the electric vehicle is started next time, a user is reminded to charge the electric vehicle before parking this time, and the situation that the user cannot use the electric vehicle due to power shortage when using the electric vehicle next time is avoided.
本申请涉及一种电动汽车充电提醒方法、系统、电动汽车和存储介质。所述方法包括:在检测到电动汽车处于停车状态的情况下,根据电动汽车的当前定位数据、历史行驶数据以及预设时长内的温度信息,来确定电动汽车在停靠结束后下一次启动使用时的预测电池温度,预测电池温度是指电动汽车停靠一段时间后电池冷却下来的电池温度,根据预测电池温度确定对应的目标电池可用容量,即结合了温度变化对于电动汽车电池容量的影响,在目标电池可用容量对应续航里程小于目标里程的情况下,表示电动汽车在下次启动时目标电池可用容量不足以支撑电动汽车驾驶至目标充电站,则提醒用户在本次停车前先进行充电,避免用户下次用车时由于缺电而无法使用。
