The invention relates to a vehicle fuse melt state detection method and device, a vehicle and a storage medium, and the method comprises the steps: traversing the historical reported faults of the vehicle, and reading an overcurrent fault or an overvoltage fault under the condition that the overcurrent fault or the overvoltage fault exists in the historical reported faults; based on an over-current fault or an over-voltage fault, at least three groups of two-end voltages of the fuse are collected; and calculating the internal resistance of the fuse melt based on the at least three groups of voltages at the two ends, checking the internal resistance by using a preset resistance-current-thermometer to obtain a checking result, and determining the state of the fuse melt according to the checking result so as to generate corresponding early warning information when the state of the fuse melt is a fault state. Therefore, the technical problem that certain potential safety hazards exist due to the lack of evaluation of the physical characteristics of the fuse melt under special working conditions in related technologies is solved.

    本申请涉及一种车辆熔断器熔体状态的检测方法、装置、车辆及存储介质,其中,方法包括:遍历车辆的历史上报故障,在历史上报故障中存在过流故障或者过压故障的情况下,读取过流故障或者过压故障;基于过流故障或者过压故障,采集熔断器的至少三组两端电压;基于至少三组两端电压计算熔断器熔体的内阻,利用预设电阻‑电流‑温度表对内阻进行核对,得到核对结果,并根据核对结果确定熔断器熔体的状态,以在熔断器熔体的状态为故障状态时,生成相应的预警信息。由此,解决了相关技术中,在特殊工况下缺少对熔断器熔体物理特性的评估,存在一定的安全隐患的技术问题。
