Resistance detection method and device, medium, program product, controller and vehicle

The invention relates to a resistance detection method and device, a medium, a program product, a controller and a vehicle. The method comprises the steps of obtaining a current environment temperature, a sampling resistance value of a first resistor, a current of a power supply system and a sampling voltage; according to the current environment temperature, the current of the power supply system and the sampling voltage, the current impedance of a connecting piece between the charging and distribution assembly shell and the vehicle body ground is determined; and correcting the sampling resistance value by using the current impedance to obtain the real resistance value of the first resistor. Therefore, the purpose of correcting the detection error of the connection confirmation signal detection circuit in real time can be achieved, the problem of inaccurate detection of the connection confirmation signal caused by poor contact between the charging and distribution assembly shell in the electric vehicle and the vehicle body ground is solved, and normal and stable operation of the charging and distribution function of the vehicle is guaranteed.
