Intelligent battery charging and discharging management system and method based on 5G cloud computing platform

Abstract

The invention discloses an intelligent battery charging and discharging management system and method based on 5G cloud computing platform. The system comprises a battery management system-on-chip based on a double-CPU framework, a 5G communication unit, a database server, the cloud computing platform, a web server and a visual terminal. The battery management system-on-chip of the double-CPU architecture is used for realizing operation state data acquisition of each battery pack and realizing SOC estimation, SOH estimation, fault diagnosis and charging and discharging control of batteries based on battery data information. The 5G communication unit is connected to the battery management system-on-chip of the double-CPU architecture and is used for transmitting the operation state information and the position information of the battery pack to the cloud computing platform in real time and receiving control parameters and signals transmitted by the cloud computing platform; the cloud computing platform is used for realizing multi-dimensional battery parameter extraction, a BMS control strategy and cooperative control of the cloud auxiliary battery management system; 5G is taken as acarrier, and active safety management and intelligent charging and discharging control of a battery pack are realized through edge calculation and cloud state estimation and correction.

Description

technical field [0001] The invention relates to the technical field of power battery management systems, in particular to a battery active and safe charge and discharge management system that uses 5G communication as a carrier and combines system-on-chip, edge computing, and cloud state estimation and charge-discharge decision-making. Background technique [0002] With the rapid development of new energy vehicles, the demand for power batteries is blowing out. The power battery system has brought great challenges to its safety due to the large-scale and group use of single batteries. In order to realize the safe and efficient management of power lithium batteries, the research and development of advanced lithium battery management systems (Battery Management System, BMS) is currently a hot and difficult issue that has attracted widespread attention. [0003] (1) Current status of foreign BMS research. Foreign countries started earlier in the field of electric vehicles, and...

AI Technical Summary

Problems solved by technology

[0005] Since many key technologies and bottlenecks have not yet been broken through, the matching degree between the BMS that is currently installed and running, the vehicle and the battery used is not high, and the traditional BMS matches and calibrates the battery based on experimental data, which is difficult to meet the needs of electric vehicles.
