How to prevent energy storage safety?

　　Now the energy processing system of lithium battery energy storage power stations (ENERGYMANAGEMENTSYSTEM (EMS) is the energy interaction of the power station. BMS controls all lithium battery unit charging and internal equilibrium. The settings cannot be changed when the control threshold is initially set; 2. After lithium battery aging, the estimation of the battery condition is estimated. As a result, the weakest battery is the most serious in losing lithium ions or forming micro -lithium branch crystals, which accelerates its aging process; 3. Lack of a diagnosis of abnormal diagnosis of battery aging, and then dynamic changes to the BMS control threshold. Use the weakest battery unit to speed up the aging feedback mechanism.

　　The Power Battery Laboratory of Shanghai Engineering and Skills University at the location of my location conducted a series of performance and durability tests from the battery unit (battery cell), battery module to the battery stack of lithium iron phosphate and ternary lithium batteries, especially the full life cycle and the life cycle and The test of retired lithium batteries, after the research of the lithium battery charging and discharging curve from abnormal to the end of life, the study of symptoms change was established. Several detection methods and confirmation algorithms of battery feature values including internal resistance were established to develop The "battery physician" suitable for fast detection, analysis and evaluation during operation can quickly check high -pressure safety hazards, position the problem of battery unit and constitute an analysis and suggestion statement.

　　Combined with the one-click analysis of the big data of Shanghai New Energy Vehicle Monitoring Center, Shanghai Meikheng Energy Storage (MAKESENS (MS Energy)) developed a defense and confirmed safety system based on the combination of cloud-edges based on Yunyuan's border skills- (PSS) (PSS), a smart communication processing machine Irouter's EnergyManagementSystem (EMS) obtained the battery filling data at the battery level in real time, analyzes, calculates, diagnose and upload it to the confirmation cloud; The cloud establishes a guessing model of its development trend and the Hengxu police threshold based on the data stream of the key battery parameters, forming a multi -parameter virtual special system; when the actual monitoring data exceeds the threshold The executable measures include replacing, balanced batteries, or updating the control parameters in the Irouter configuration file to provide dynamic control strategy updates for BMS.
