The invention discloses a vehicle state monitoring and warning method in a V2G charging pile, and relates to the technical field of vehicle charging monitoring and early warning. Corresponding actions of the charging pile, voltage and current output information and vehicle end battery state information in the discharging process are collected in real time, and all the information collected by the charging pile is subjected to time marking; the message is received from the vehicle end; predicting the state of the vehicle end battery, and judging whether a predicted value or trend is consistent with the actual parameter change value or trend of the battery or not, or is within a certain error allowable range; if the conditions are met, continuously keeping discharging; otherwise, the charging pile actively reduces the output power and triggers early warning; and after each time of discharging is normally ended or abnormally ended, the collected data and analysis results are stored in a local historical file and reported to an operation and maintenance cloud platform. Potential faults and risks are prevented by monitoring and evaluating the state of the vehicle battery in real time, and the safety and efficiency of discharging operation are improved.

    本发明公开了一种V2G充电桩中的车辆状态监测与告警的方法,涉及汽车充电监测与预警技术领域。实时采集放电过程中充电桩相应动作和电压电流输出信息、车端电池状态信息,对充电桩采集到的所有信息进行标注时间;且从车端接收报文;对车端电池状态进行预测,并判断预测值或趋势和电池实际参数变化值或趋势是否一致,或在一定的误差允许范围内;若满足条件,将继续保持放电;否则充电桩将主动减小输出功率并触发预警;在每次放电正常结束或者异常终止后,将采集到的数据和分析结果保存至本地历史文件并上报至运维云平台。本发明通过实时监测和评估车辆电池的状态来预防潜在的故障和风险,提高放电操作的安全性和效率。
