A DC converter, a controlling method, and a vehicle are provided. The DC converter includes: a first inductor, a switching unit, a diode, a first capacitor, a load resistor, a pre-charge control unit and a controller. The output terminal of the controller is connected with the control terminal of the switching unit and the control terminal of the pre-charge control unit. The controller is configured to control the switching unit to be turned on or turned off, and to control the resistor connected between the negative electrode of the diode and the first end of the load resistance in the pre-charge control unit when the switching unit is turned off, such that the direct current converter is pre-charged by the low-voltage power supply.
