Embodiment Construction

[0034] In order to understand the content of the present invention more clearly, it will be described in detail with reference to the drawings and embodiments.

[0035] Such as figure 1 Shown is a schematic diagram of the principle of the power battery balance management system. The system consists of a physical battery module, a digital battery module, a digital twin module, and a cloud analysis module. The physical battery module and the digital battery module communicate with the digital twin through wired or wireless methods The data transmission of the module enables the digital twin module to receive and couple the basic data transmitted by the physical battery module and the digital battery module, and according to the basic data to identify system parameters, estimate and calibrate the real-time status, and perform performance evolution on the system, obtain the digital twin data and convert the basic The data and digital twin data are sent to the cloud analysis module...

Abstract

The present invention relates to a power battery balance management system and method. The digital twin technology is used to establish a power battery balance management system based on cloud control. At the same time, the actual operation data and simulated operation data are collected for analysis and calculation, which can effectively weaken the current battery system. Inconsistency and the disturbance of reducing the inconsistency of the future battery system, in order to achieve the purpose of managing the inconsistency of power battery and controlling the development direction of inconsistency in the future.

Description

technical field [0001] The invention relates to the technical field of power battery management, in particular to a power battery balance management system and method. Background technique [0002] Electric vehicles usually use lithium-ion batteries as energy storage components, and single batteries are combined in series and parallel to form a power battery pack to provide energy for driving motors and other high-voltage electrical systems. There are differences in internal materials and fine structures of batteries when they leave the factory, resulting in inconsistencies in voltage, capacity, and internal resistance among single batteries. This inconsistency will affect the charge and discharge rate of the battery and the self-discharge rate during the static state during the charge and discharge cycle of the battery pack, leading to the gradual expansion of the inconsistency between the batteries, which not only accelerates the aging process of the battery, but also caus...
