The invention provides a contactor sintering detection method and device and a vehicle. The contactor sintering detection method comprises the steps that voltage is applied to the two ends of a contactor, the current value of an induction coil of the contactor is obtained, and it is determined that the contactor is sintered according to the change of the current value. According to the contactor sintering detection method and device and the vehicle, voltage is applied to the two ends of the contactor, it is determined that the contactor is sintered according to the change of the current value, and the detection reliability is high.

    本发明提供了一种接触器烧结检测方法、装置及车辆。其中接触器烧结检测方法包括:对接触器两端施加电压,获取接触器的感应线圈的电流值,根据电流值的变化确定所述接触器发生烧结。本发明的接触器烧结检测方法、装置及车辆,通过对接触器两端施加电压,根据电流值的变化确定所述接触器发生烧结,检测可靠性高。
