Deng Honggang, Director of Strategic Planning at Xi'an Golden stone Electric Technology Co., Ltd., gave a special speech entitled 'Smart Energy Storage Solution for Centralized Control Chain', pointing out the main factors affecting the safety and economy of energy storage systems, and proposing a smart energy storage solution for centralized control chain.
On June 20, 2019, the 2019 High Tech Lithium Energy Storage Conference with the theme of opening up the G era with lithium energy storage was successfully held in Shenzhen. Xi'an Golden stone Electric Technology Co., Ltd., as an invited guest of the conference, gave a special speech entitled "Smart Energy Storage Solution for Centralized Control Chain" and won the Best PCS Supplier Award in China's energy storage industry.
The common requirements of the energy storage industry are safety, stability, durability, and economy, among which safety and economy have become two hot topics and are the core issues that the upstream and downstream of the energy storage industry must urgently solve together. ”Mr. Deng Honggang, Director of Strategic Planning at Xi'an Jingshi Electric Technology Co., Ltd., pointed out the main factors affecting safety and economy at the beginning of his speech, and proposed a centralized control chain intelligent energy storage solution.
Mr. Deng Honggang introduced the intelligent energy storage solution of the centralized control chain, which independently controls each battery and conducts refined management to achieve one-to-one control, reduce the series parallel mismatch of batteries, and improve the recyclability of batteries. It completely solves the problems of multiple series connections of batteries in traditional energy storage power stations, large number of PCS connected batteries, difficult management and control, and single battery failure leading to the disconnection of the entire battery stack from the system. ”Mr. Deng Honggang mentioned in his speech.
Regarding the centralized control chain solution, Deng Honggang stated that Jingshi Technology's intelligent energy storage solution for centralized control chain is designed and controlled from three dimensions: centralized, control, and chain.
Collection of Centralized Control Chain
'Ji' mainly refers to integration, which integrates the PCS system with BCU, PCU, SCU, and EMS units. BCU is responsible for battery and DC/DC data acquisition and processing; PCU collects AC/DC unit data and uploads it to SCU, and performs logical control according to SCU instructions. SCU communicates with BCU, PCU, electricity meters and other devices to achieve data processing, strategic control and human-computer interaction; At the same time, an EMS system is also integrated internally.
Control of the centralized control chain
Control "mainly refers to intelligent management and control. The EMS integrated within the PCS of the centralized control chain is called Access, which is a device level EMS. It is based on BMS's intelligent management and control of battery charging and discharging, and this function runs through the entire charging and discharging process. When BMS protection fails, it can still ensure the safety and reliability of charging and discharging, such as battery overvoltage, overcharging, BMS failure, upload data not updated or incorrect, intelligent control detects abnormal battery and BMS status, and actively terminates charging and discharging. Moreover, it has information recording and playback functions, similar to the black box of an energy storage system, which can actively record key data before and after the occurrence of faults for problem localization, analysis, and resolution.
Chain "mainly refers to multi-point chains, interconnected sharing, data interconnection, efficient and diverse data transmission, meeting the transmission efficiency requirements for big data control of energy storage power plants. To lay the foundation for adapting to the ubiquitous power Internet of Things, achieving comprehensive knowledge, element interconnection, information sharing, data-driven, and machine learning functions.
At the end of his speech, Mr. Deng Honggang summarized, "Xi'an Jingshi Electric Technology Co., Ltd. has the mission of 'providing users with more economical, convenient, and efficient solutions for energy management and application', and the vision of 'solving the spatiotemporal problems of power production and application, and building an intelligent world of energy interconnection'. Through continuous technological innovation, we aim to maximize customer value, lead the market with high-quality products, promote the technological upgrading of the energy storage industry, and promote the rapid development of the industry
At the award ceremony, Xi'an Jingshi Electric Technology Co., Ltd. was awarded the Best PCS Supplier Award in China's Energy Storage Industry by the High Tech Industry Research Institute and the High Tech Lithium Battery Organizing Committee.
In short, Jingshi Technology always takes customer satisfaction as its responsibility, takes the healthy development of the industry as its starting point, continuously innovates from various dimensions, and works hand in hand with industry peers to contribute to welcoming the era of lithium-ion energy storage G.
