The invention discloses a battery pack heating circuit control method and device, a storage medium and computer equipment, and relates to the technical field of circuit control. The method is applied to the battery pack heating circuit, the battery pack heating circuit comprises an electric heating device arranged at the position of a battery pack, a switch device for controlling the electric heating device and a power bus to establish a circuit access and a controller for conducting on and off control on the switch device, and the controller is used for executing the method. The method comprises the following steps: determining output power to be output of the electric heating device, and collecting a voltage value at a power supply bus in real time; based on the output power, the voltage value and the resistance value of the electric heating device, the duty ratio of an electric pulse circulation signal used for controlling on or off of the switch is calculated; and an electric pulse circulation signal is sent to the switching device to control the switching device to be switched on or switched off. According to the method, the safety of heating work of the battery pack can be remarkably improved.
