The invention discloses an anti-creeping early warning protection method based on vehicle-mounted charging, relates to the technical field of electric vehicles, and solves the problems that an existing fixed threshold monitoring mode is extremely easy to generate false alarm; in order to solve the technical problem that accidental data cannot be further distinguished due to the quality problem of equipment, improper installation, poor use environment and the like, two sets of preset threshold value groups are arranged in a main controller, and the state of the battery pack is judged by monitoring the dynamic change of the voltage of the battery pack, so that the reliability of the battery pack is improved. Calling out a corresponding preset threshold group; the method comprises the following steps of: drawing parameters such as real-time voltage and real-time temperature of each element into a curve changing along with time through a main controller, taking a plurality of points in each period by taking T as a period so as to solve the variance of the voltage in each period, comparing the variance with preset variances in a corresponding preset threshold group one by one, and performing corresponding marking according to a comparison result.
本发明公开了基于车载充电的防漏电预警保护方法,本发明涉及电动汽车技术领域,解决了现行的固定阈值监测方式极易产生误报,对于设备本身的质量问题、安装不当、使用环境不佳等问题所造成的偶然数据没有进一步的辨别方法的技术问题,本发明通过在主控制器内设置两套预设阈值组,经过监测电池包电压的动态变化,判断其所处状态,然后调出对应的预设阈值组;通过主控制器将各元件的实时电压和实时温度等参数绘制成随时间变化的曲线,以T为一个周期,在每个周期内取若干个点,以此求出每个周期电压的方差,并逐个与对应预设阈值组中的预设方差相比较,根据比较结果进行相应标记。
