The invention discloses a charging abnormity diagnosis and evaluation system of a mobile charging vehicle, and belongs to the technical field of charging abnormity diagnosis of charging vehicles. Charging abnormity analysis is carried out in two directions of charging vehicle equipment and a charging pile, and comprehensive judgment is carried out in combination with a charging environment temperature; according to the method, the charging rate of the charging vehicle is analyzed before and after temperature rise, whether the environment temperature affects the charging rate of the charging vehicle or not is judged, and after a charging indirect abnormal signal of the charging vehicle is obtained, analysis is carried out by combining the voltage load deviation degree of the charging pile and the temperature influence floating value; the real-time operation influence analysis coefficient of the charging pile is generated and compared to judge whether the operation of the charging pile is abnormal or not, the accuracy of charging abnormity judgment is effectively improved through one-way and two-way combined analysis of the input end and the output end, and maintenance pertinence is achieved.

    本发明公开了一种移动充电车的充电异常诊断评估系统,属于充电车充电异常诊断技术领域,本发明是通过充电车设备以及充电桩两个方向进行充电异常分析,并结合充电环境温度来综合判断,即结合升温前和升温后对充电车的充电速率进行分析,判断环境温度是否影响充电车的充电速率,当得到充电车充电间接异常信号后,再结合充电桩电压负载偏离度、温度影响浮动值进行分析,生成充电桩的实时运行影响分析系数并进行比较,来判断充电桩运行是否异常,通过对输入端、输出端单向以及双向结合分析,有效提高充电异常判断的准确性,且具有维护针对性。
