Problems solved by technology

The calculation of state parameters such as SOC requires the help of the battery energy management system BMS. During the research and development process, the inventor found that the BMS of the battery module can only realize the simple calculation of data. The computing power of the processor itself is limited, and it is difficult to realize the calculation of complex and high-precision prediction algorithms. Obviously, the BMS calculation accuracy is not high, and the actual situation of the battery module cannot be accurately grasped.

Abstract

The utility model discloses an intelligent battery SOC management system and method based on a cloud platform. The system comprises a BMS system configured to collect operation parameters of a batterymodule and environmental parameters of the current equipment and upload the operation parameters and the environmental parameters to the cloud server, calculate a SOC value of the battery module according to the operation parameters of the battery module, receive a regulation and control instruction and a new correction coefficient issued by the cloud server, and correct the calculated SOC value;and a cloud server configured to receive the operation parameters of the battery module and the environmental parameters of the current equipment acquired by the BMS system, analyze and process the operation parameters and the environmental parameters, and establish a corresponding operation parameter and environmental parameter database, and judge whether the battery SOC parameters need to be re-corrected according to the operation parameters, issue the regulation and control instruction to the BMS system if the battery SOC parameters need to be re-corrected, re-adjust the correction coefficients according to the operation parameters of the battery module and historical operation parameter information thereof to obtain new correction coefficients, and issue the new correction coefficients to the BMS system.

Description

technical field [0001] The present disclosure relates to the technical field of power batteries, in particular to an intelligent battery SOC management system and method based on a cloud platform. Background technique [0002] With the rapid development of my country's economy, society and new energy industry, power batteries are widely used in electric buses, electric vehicles, large energy storage systems, etc. The battery cells are connected in series and parallel to form a battery module for reuse. However, the performance of the battery cells in the module is different. It is necessary to use the BMS to improve the battery utilization rate and realize the dynamic monitoring of the battery. Accurately estimating the battery SOC is the function of the BMS. premise. However, the traditional BMS is limited by the operation speed and storage capacity, and the calculation accuracy of its SOC algorithm is not high. Moreover, the existing BMS calibration is completed before l...
