The invention relates to the technical field of electric data processing, and provides an instrument electric quantity intelligent calibration method and system, and the method comprises the steps: obtaining the model information of a power supply; after charging is completed, driving mileage data, the highest driving speed, the lowest driving speed and the constant-speed driving speed are started and obtained, and corresponding experience data and historical charging and discharging records are collected; a model correction factor is determined by using power model information and power loss information, an electric energy conversion model is set by combining empirical data and historical charging and discharging records, mileage data, a highest driving speed, a lowest driving speed and a constant driving speed are input, a residual electric quantity calibration result is output, the residual electric quantity is corrected, and the residual electric quantity is displayed and output at the same time. The technical problem that the electric quantity of the vehicle instrument cannot truly reflect the remaining electric quantity of the vehicle-mounted battery pack is solved, the electric quantity of the vehicle instrument is calibrated from multiple dimensions of driving speed, driving mileage and power loss, and the technical effect of reflecting the remaining electric quantity of the vehicle-mounted battery pack more accurately in real time is achieved.

    本发明涉及电数据处理技术领域,提供了一种仪表电量智能校准方法及系统,方法包括:获取电源型号信息;完成充电后,启用并获取行驶里程数据、最高行驶速度、最低行驶速度、匀速行驶速度,采集对应的经验数据、历史充放电记录;利用电源型号信息、电源损耗信息确定模型修正因子,并结合经验数据、历史充放电记录,设置电能转换模型并输入行驶里程数据、最高行驶速度、最低行驶速度、匀速行驶速度,输出剩余电量校准结果并校正剩余电量同时显示输出,解决车辆仪表电量无法真实反映车载电池组的剩余电量技术问题,实现从驾驶速度、驾驶里程、电源损耗多维度进行车辆仪表电量校准,以达到更精确、更实时的反映汽车车载电池组的剩余电量技术效果。
