The invention discloses a method, device and equipment for a motor controller to obtain DC power supply voltage and a medium. The method for the motor controller to obtain the DC power supply voltage comprises the following steps: respectively obtaining first reference DC power supply voltage collected by a target sampling circuit and second reference DC power supply voltage collected by a battery management system; and determining a trusted DC power supply voltage according to the first reference DC power supply voltage and the second reference DC power supply voltage. The reliability of the obtained credible direct-current power supply voltage is improved, and a foundation is laid for downstream control of a motor controller.
