The invention provides a new energy automobile battery management method and system, a computer and a storage medium, the method is used for switching a power supply of an automobile data recorder on an automobile, and the method comprises the steps that when the automobile is static, whether the parking state of the automobile is a long-time retention state or not is judged; if the vehicle is in the long-time retention state, acquiring opening information of a vehicle window and a protection state of a vehicle door, and judging whether to trigger distance judgment between the vehicle and the intelligent key or not according to the opening information of the vehicle window and the protection state of the vehicle door; if so, circularly acquiring distance information between the vehicle and the intelligent key within the calibration time, and judging whether the distance information exceeds a distance threshold value or not; and if the distance exceeds the distance threshold value, cutting off the electric connection between the battery module and the automobile data recorder, and controlling the auxiliary battery module to be electrically connected with the automobile data recorder. By arranging the independent auxiliary battery module, the power supply can be provided for the automobile data recorder after the whole automobile is powered off, comprehensive judgment is carried out according to various kinds of information, the power supply can be switched on the basis, and continuous operation of the automobile data recorder is continuously guaranteed.

    本发明提供一种新能源汽车电池管理方法、系统、计算机及存储介质,方法用于切换车辆上行车记录仪的供电源,方法包括:当车辆静止时,判断车辆的停车状态是否为长时滞留状态;若为长时滞留状态,则获取并根据车窗的开度信息及车门的防护状态判断是否触发车辆与智能钥匙之间的距离判定;若触发,则于标定时间内循环获取车辆与智能钥匙之间的距离信息,并判断其是否超过距离阈值;若超过距离阈值,则切断电池模组与行车记录仪之间的电性连接,并控制辅助电池模组电性连接行车记录仪。通过配备单独的辅助电池模组,可在整车断电后为行车记录仪提供供电源,根据多种信息综合判定,可以此为依据切换供电源,持续保障行车记录仪的持续运行。
