Abstract

The invention provides a dual battery pack vehicle energy management method, device, apparatus and storage medium. The vehicle comprises a first battery pack and a second battery pack. The vehicle energy management method of the dual battery pack comprises the following steps of: calculating a prediction value corresponding to an influence factor according to an influence factor of a second battery pack and an action function corresponding to the influence factor; calculating a total predicted value for replacing the second battery pack according to the predicted values of the n influence factors and the weight of the n influence factors; if the total predicted value is greater than the first threshold value, the second battery pack is predicted to be replaced within the first time periodthreshold value and the vehicle is brought into the first energy management mode. If the total predicted value is less than the second threshold value, it is predicted that the second battery pack will not be replaced within the first time period threshold value and the vehicle is brought into the second energy management mode. If the total prediction value is greater than or equal to the second threshold and less than or equal to the first threshold, the vehicle is maintained in a previous energy management mode. The system and method of the present invention optimizes energy management.

Description

technical field [0001] The invention relates to the field of electric vehicle battery management, in particular to a vehicle energy management method, device, equipment and storage medium for dual battery packs. Background technique [0002] In existing electric vehicles, two battery packs, primary and secondary, are usually installed to improve the battery life of the electric vehicle. For example, an electric vehicle can include a main battery pack and a secondary battery pack. The main battery pack has a large capacity and high charging and discharging power, and is installed on the vehicle in a fixed manner. It is the main energy source of the electric vehicle; Low power, installed on the vehicle in a quick-change manner, is a secondary energy source for electric vehicles to increase the mileage of the vehicle. [0003] For the charging and discharging of the main battery pack and the secondary battery pack, that is, the energy management strategy of the dual pack, most...
