The invention discloses a fault early warning method and device, a battery, a vehicle and a storage medium. The method comprises the steps of collecting original parameter data of a target object in a first time window; according to the original parameter data of the early warning risk range, parameter data of fault assessment features of the target object in a second time window are determined, the fault assessment features are determined based on the target working condition, the early warning risk range is at least one target object in a set range, and the time length of the second time window is the same as that of the first time window; the data volume in the first time window is greater than the data volume in the second time window; and determining the fault early warning time of the target object under the target working condition according to the parameter data of the fault assessment features and the corresponding parameter fault threshold.

    本申请公开了一种故障预警方法、装置、电池、车辆及存储介质,方法包括:采集第一时间窗口内的目标对象的原始参数数据;根据预警风险范围的原始参数数据,确定目标对象在第二时间窗口内的故障评估特征的参数数据,故障评估特征基于目标工况确定,预警风险范围为设定范围内的至少一个目标对象,第二时间窗口与第一时间窗口的时间长度相同,第一时间窗口内的数据量大于第二时间窗口内的数据量;根据故障评估特征的参数数据和对应的参数故障阈值,确定目标对象在目标工况下的故障预警时间。
