The invention discloses a fault detection method and device, equipment and a storage medium, which are used for detecting and recording faults in a charging process and facilitating monitoring and backtracking of the faults. Determining that a first specified signal sent by the charging gun is received, and starting timing; if it is determined that the duration of receiving the first specified signal reaches the first preset duration, determining a fault type based on the received PWM wave duty ratio sent by the charging gun; and uploading the fault type to a whole vehicle communication bus. In the application, whether a fault occurs in the charging process is determined according to the duration of receiving the first specified signal, real-time monitoring of the charging process is realized, after the fault is determined, the fault type is determined according to the PWM wave duty ratio and uploaded to the whole vehicle communication bus, real-time uploading of the fault is completed, and the fault is convenient to backtrack.
本申请公开了一种故障检测方法、装置、设备和存储介质,用于检测充电过程中的故障并记录,便于对故障进行监控及回溯。确定接收到充电枪发送的第一指定信号,并开始计时;若确定接收到第一指定信号的持续时长达到第一预设时长,则基于接收到的充电枪发送的PWM波占空比确定故障类型;将故障类型上传至整车通讯总线。在本申请中,通过接受到第一指定信号的持续时长来确定在充电过程中是否出现了故障,实现了对充电过程的实时监控,在确定出现故障后,通过PWM波占空比确定故障类型并上传至整车通讯总线,完成了故障的实时上传,便于对故障进行回溯。
