The invention provides a method for preventing false alarm of a relay adhesion fault, a battery management system and a vehicle, the method is applied to the battery management system of the vehicle, and the battery management system comprises a time delay module; the method comprises the following steps: if a first gun insertion signal of a charging gun is obtained, inputting the first gun insertion signal into a time delay module, and entering a time delay mode; determining an output signal of the time delay module based on a preset calibration quantity in the time delay module; and judging whether to quit the delay mode based on the output signal, and performing relay adhesion detection after quitting the delay mode. According to the invention, the problem of relay adhesion fault false alarm caused by rapid gun pulling and inserting by a user can be improved.
本发明提供了一种防止误报继电器粘连故障的方法、电池管理系统及车辆,该方法应用于汽车的电池管理系统,电池管理系统包括延时模块;该方法包括:如果获取到充电枪的第一插枪信号,则将第一插枪信号输入到延时模块,进入延时模式;基于延时模块中预设的标定量,确定延时模块的输出信号;基于输出信号判断是否退出延时模式,并在退出延时模式后进行继电器粘连检测。本发明能够改善由于用户快速拔枪插枪导致继电器粘连故障误报的问题。
