Power module, electric control assembly and vehicle

The utility model provides a power module, an electric control assembly and a vehicle, and the power module comprises a power module body; a plurality of first input terminals; a plurality of first output terminals; wherein each of the first input terminal and the first output terminal comprises a hot melting area, the hot melting area of the first input terminal is used for being connected with a second output terminal of a first device, and the hot melting area of the first output terminal is used for being connected with a second input terminal of a second device. According to the power module, the electric control assembly and the vehicle, the contact resistance and the contact thermal resistance are small through the welding technology achieved through the hot melting area, after the power module body is installed between the first device and the second device, the overall equivalent inductance is reduced, the loss is reduced, the switching frequency is increased, the overheating problem is not prone to
