The invention discloses a safety early warning method and device for a fuel cell system. The method comprises the steps: acquiring vehicle data of a vehicle, wherein the vehicle data comprises charging data and/or operation data; performing normalized discrete wavelet decomposition processing on the vehicle data to obtain charging abnormal data and/or operation abnormal data; judging whether the charging abnormal data meets a risk condition or not, and/or judging whether the operation abnormal data meets an early warning condition or not; and when the risk condition is met, judging that the vehicle has a risk, controlling the vehicle to stop charging, meanwhile, performing charging risk prompting, and/or when the early warning condition is met, generating risk prompting information and/or safety information, and sending the risk prompting information and/or the safety information to the preset terminal. According to the method, online identification and accurate positioning of early risk signals are realized, and multi-level risk early warning for a real vehicle fuel cell system is realized.

    本发明公开了一种燃料电池系统的安全预警方法及装置,其中,方法包括:获取车辆的车辆数据,其中,车辆数据包括充电数据和/或运行数据;对车辆数据进行归一化离散小波分解处理,得到充电异常数据和/或运行异常数据;判断充电异常数据是否满足风险条件,和/或判断运行异常数据是否满足预警条件;在满足风险条件时,判定车辆存在风险,控制车辆停止充电的同时进行充电风险提示,和/或,在满足预警条件时,生成风险提示信息和/或安全信息,并发送风险提示信息和/或安全信息值预设终端。该方法实现了早期风险信号的在线识别和精准定位,并且实现面向实车燃料电池系统的多级风险预警。
