Management method of power battery module based on cloud control technology

Abstract

The invention relates to a management method of a power battery module based on a cloud control technology. The power battery module is used as a physical entity in an actual working environment, andthe method comprises the following steps: firstly, establishing a digital twined virtual power battery module model matched with a physical entity in a simulation environment of a cloud computing platform based on a digital twinning technology; configuring a simulation working environment of the model; collecting physical data generated by the operation of the physical entity and virtual data generated by the operation of the virtual power battery module model through the cloud computing platform and then performing data analysis and fusion processing; and correcting and updating the virtual power battery module model at the cloud according to the data processing result, and obtaining a corresponding optimal control strategy under the latest model based on the physical entity calibration performance and the current state in combination with an online simulation technology. The cloud computing platform inputs the optimal control strategy into the battery management system based on a cloud control technology so as to automatically control the operation of the physical entity and update feedback in real time, thereby integrally realizing dynamic optimal management.

Description

technical field [0001] The invention relates to the technical field of management of power battery modules of electric vehicles, in particular to a management method of power battery modules based on cloud control technology. Background technique [0002] The energy storage device on the car - the power battery module is a key component of the electric vehicle. When the power battery module encounters overcharge, overdischarge, etc., it will shorten the service life of each battery cell and may cause safety problems And endanger the safety of automobile and occupant. In order to protect the power battery module and prevent safety accidents, people usually add a battery management system (BMS) to the power battery module to monitor and manage the status of the power battery module. The battery management system (BMS) monitors and controls the state of the power battery module based on a preset program architecture, but the power battery module in the process of charging and ...
