The invention relates to a control method and device of an engine system, a storage medium and electronic equipment, the engine system comprises a motor used for adjusting a variable compression ratio mechanism and a power supply module, the power supply module jointly provides power for the motor and other electric devices in the engine system, and the control method comprises the steps that the output voltage Ub of the power supply module is obtained; when the output voltage Ub of the power supply module is smaller than a first preset value and larger than or equal to a second preset value, the compression ratio of the engine is adjusted to be smaller than or equal to a first compression ratio by adjusting the variable compression ratio mechanism, and then the motor is controlled to be powered off; when the output voltage Ub of the power supply module is smaller than a second preset value, the motor is controlled to be powered off. Therefore, when the power supply module is abnormal, the adjusting motor of
