Multi-class multi-quantity power battery charging coordination device

Abstract

This invention discloses a multi-type, multi-quantity power battery charging coordination device, relating to the field of battery charging control technology. The device includes a parameter acquisition module, a data preprocessing module, a digital twin modeling module, a simulation optimization module, and a charging control module. The invention acquires state parameter information of the power batteries through the parameter acquisition module, preprocesses the data, and transmits it to the digital twin modeling module to construct a digital twin model covering all power batteries. Simultaneously, the simulation optimization module establishes an adaptation benchmark library containing characteristic data of various power batteries and calls the digital twin model to conduct multiple rounds of virtual simulation experiments. Differentiated charging combination parameters are set, and the battery response process is simulated. After recording changes in data, the combination parameters are iteratively adjusted. The final combination parameters are selected through an adaptability evaluation index to form a preliminary charging scheme, achieving precise matching of the charging strategy with the characteristics of different types of power batteries and ensuring the coordination of the charging process.
