The invention relates to the technical field of charging management, and discloses a new energy automobile charging management system based on big data, and the system comprises the steps: collecting the temperature of a water inlet and the temperature of a water outlet of a cooling pipeline, and obtaining the temperature difference between the inlet and outlet of the cooling pipeline; the method comprises the following steps: acquiring the ambient temperature when the vehicle-mounted charging equipment works and the cavity temperature when the vehicle-mounted charging equipment works to obtain an internal and external temperature difference, acquiring the current heat consumption of the vehicle-mounted charging equipment, and calculating the flow of the cooling liquid through acquired parameters to realize accurate prediction of the flow of the cooling liquid; the cooling liquid flow is compared with the preset interval, whether the cooling liquid flow meets the requirement or not is judged, and if the cooling liquid flow does not meet the requirement, the cooling liquid pipeline is adjusted by analyzing the flow.

    本发明涉及充电管理技术领域,公开了一种基于大数据的新能源汽车充电管理系统,本发明采集冷却管道进水口温度和出水口温度,得出冷却管道进出口温度差,采集车载充电设备工作时的周围环境温度和车载充电设备工作时的腔体温度得出内外温度差,采集车载充电设备的当前热耗量,通过采集到的参数计算得出冷却液流量,实现对冷却液流量精准预测,然后,通过将冷却液流量与预设区间对比,判断冷却液流量是否满足需求,若不满足需求,通过对流量进行分析,对冷却液管道进行调整。
