Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] figure 1 and 2 As shown, a generalized battery management system proposed by the present invention includes a traditional local battery management system and an offline state evaluation system;

[0034] The local battery management system includes all basic functional modules of current mainstream battery management systems, including battery parameter detection module, state of charge and power state estimation module, charge and discharge management module, but correspondingly added battery data screening module, battery data An uploading module and an offline status evaluation result receiving module.

[0035] The local battery management system conducts online detection of battery parameters (including voltage, current, temperature, and charge and discharge capacity), estimates the state of charge and power state based on the detected battery par...

Abstract

The invention relates to a generalized battery management system for energy storage of new energy vehicles and batteries and provides a generalized battery management system of combining a local battery management system and an offline state evaluation system which runs on a remote big data platform, wherein the local battery management system detects battery parameters (a voltage, a current, a temperature and charge-discharge capacity) in real time, estimates the battery state according to the detected battery parameters, judges whether an abnormal state appears or not, achieves local real-time charge-discharge management and uploads the detected battery parameters to the remote big data platform; and the offline state evaluation system runs on the remote big data platform, estimates the health state of the battery and carries out risk pre-warning according to the historical battery parameters stored in a database and the real-time battery parameters, resets charge-discharge control parameters according to the health state of the battery, dynamically updates a management strategy, gives battery maintenance information and transmits the result to the local battery management system.

Description

technical field [0001] The invention relates to the field of battery management of power lithium-ion batteries, in particular to a generalized battery management system suitable for new energy vehicles and lithium-ion battery energy storage. Background technique [0002] With the rapid development of the automobile industry and the rapid increase of urban population and vehicles, the fuel consumption of the urban transportation system will also increase sharply, and the environmental pollution caused by it will become more and more serious. In order to cope with the increasingly serious environmental pollution and energy crisis, the development and popularization of new energy vehicles is imminent. [0003] With the development of smart grid and the widespread access of distributed energy generation such as wind power and photovoltaic power generation to the grid, a large number of energy storage systems are required to be connected to the grid. As the core component of the...
