The invention relates to a boost charging control method and device, computer equipment and a storage medium. The method comprises the steps of obtaining motor parameters under the condition that a boost charging instruction is obtained; the motor parameters comprise one or more of motor bus voltage and motor mechanical rotating speed; under the condition that the motor parameters meet the code switching condition, code switching is carried out; the code switching is used for changing a three-phase current sampling point of a bottom code of the motor controller; code switching is detected, and boost charging control is carried out when it is detected that the code switching is correct. By adopting the method, the current sampling accuracy of boost charging can be directly improved by switching bottom layer codes and replacing a current sampling mode, manual calibration with large workload is not needed, and after the current sampling accuracy is improved, the current control accuracy can be improved, the torque fluctuation possibly output by the motor is reduced, and the reliability of boost charging is improved. And the boost charging efficiency is improved.
