Energy storage system safety control method and control system

Abstract

The invention provides an energy storage system safety control method and control system, and the energy storage system safety control method comprises the steps that: a data collection module collects the operation data of a battery cell of an energy storage system, and transmits the operation data to edge-end equipment; the edge-end equipment analyzes and processes the battery cell operation data and sends the battery cell operation data to cloud-end equipment; the cloud equipment analyzes and processes the battery cell operation data and sends an analysis and processing result to the edge-end equipment; and analysis and processing results of the edge-end equipment and the cloud-end equipment are integrated, and a battery cell control strategy is output. According to the safety control method of the energy storage system, the operation processing of the operation data of the battery cell is carried out by the edge-end equipment and the cloud-end equipment at the same time, the rapid real-time judgment capability of the edge-end equipment and the big data analysis capability of the cloud-end equipment are fully utilized, the advantage of cloud-side cooperation is exerted, and the safety early warning, rapid processing and automatic analysis response of the battery cell are realized, therefore, the safety of the energy storage system cell is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of energy storage system control, in particular to an energy storage system safety control method. At the same time, the present invention also relates to an energy storage system safety control system capable of implementing the above energy storage system safety control method. Background technique [0002] In the energy storage system, the safety of the battery cell is the most critical, which may lead to severe events such as explosion and combustion. Therefore, it is most important to ensure the safety of the battery cell during the operation of the energy storage system. [0003] The smallest constituent unit of the energy storage system includes a single battery cell. Multiple single battery cells are connected in series or in parallel to form a sub-box, and a first-level BMS is installed in each sub-box, which is mainly responsible for the voltage and temperature data of the battery cells. The analo...

Problems solved by technology

[0006] 1. The BMS protection method at the device side is only based on the transient analysis of independent data, and it cannot be early predicted, detected and dealt with slowly decaying cells, leading to the deterioration of the situation

[0007] 2. The current offline analysis method for historical data will lead to untimely response or processing, and consume manpower
