The invention belongs to the technical field of automobiles, and particularly relates to a power battery SOP switching control method based on a storage battery model. Determining the maximum allowable power Map of the power battery in different states in the charging direction and the discharging direction; 2, switching the maximum allowable power Map based on the operation condition of the power battery; and step 3, establishing a reservoir model according to the maximum allowable power Map, calculating the available power of the power battery, and sending the available power to the controller. Estimation of SOP values is completed through test data, SOP estimation values are sent to other controllers at the vehicle end, power switching under different load or charging working conditions is completed in real time, and the method has very obvious advantages in calculation method and software implementation.
