The embodiment of the invention discloses a vehicle charging heat preservation method and device and a new energy vehicle. The vehicle charging heat preservation method comprises the steps of obtaining electric quantity information of a battery of a vehicle in the charging process; judging whether the electric quantity information is equal to or greater than a first threshold value in real time, wherein the first threshold value is smaller than the full electric quantity of the battery; if yes, controlling a power utilization device of the vehicle to be started, so that the charging pile and the battery supply power to the power utilization device; and according to the discharge condition of the battery and/or the temperature condition of the battery, controlling the power utilization device to be turned off, so that the charging pile charges the battery. According to the method of the invention, after the vehicle is charged, the temperature of the battery is not influenced by the ambient temperature, and the battery is kept in a good to-be-discharged state.

    本发明实施例公开了一种车辆充电保温方法、装置及新能源汽车。车辆充电保温方法包括:获取车辆的电池在充电过程中的电量信息;实时判断电量信息是否等于或大于第一阈值,其中第一阈值小于电池的满电电量;若是,则控制车辆的用电装置开启,以使充电桩和电池均向用电装置供电;根据所述电池的放电状况和/或所述电池的温度状况,控制所述用电装置关闭,以使所述充电桩向所述电池充电。本实施例保证了车辆充完电后,电池的温度不会被环境温度影响而保持良好的待放电状态。
