On September 28, 2019, the Energy Storage International Innovation Forum 2019 was successfully held in Nanjing. Xi'an Jingshi Electric Technology Co., Ltd., as an invited guest at this conference, gave a special speech entitled "Smart Energy Storage Solution for Centralized Control Chain", which once again attracted the attention of attending experts and guests.
Safety and economy are the two hot topics in the energy storage industry, and they are the core issues that the upstream and downstream of the energy storage industry must urgently solve together. "Mr. Deng Honggang from Xi'an Golden stone Electric Technology Co., Ltd. mainly focused on the characteristics that affect the safety and economy of smart energy storage solutions for centralized control chains in his speech.
Centralized control chain intelligent energy storage solution of GSSTES refers to a smart energy storage solution that deeply integrates power electronics technology with intelligent control, and highly integrates information technology. For each battery, it is independently controlled and finely managed. Based on the 3U control system, it improves the cycle life of the battery and increases the revenue within the life cycle. Thoroughly solve the problems of multiple series parallel connections of batteries in traditional energy storage systems, large number of PCS connected batteries, difficult management and control, and barrel effect. ”Mr. Deng Honggang mentioned in his speech.
In the speech, detailed explanations will be given from both safety and economic perspectives, based on project cases.
Centralized control chain safeguards the security of energy storage systems
In response to the safety hazards caused by improper use of batteries, unreasonable electrical design, and unreasonable PACK design in traditional energy storage solutions, a centralized control chain intelligent energy storage solution is proposed. The system uses BCU, PCU, SCU, and EMS to coordinate and control the system, achieving fault warning and solving system safety hazards.
The centralized control chain intelligent control system establishes a multidimensional linkage protection model for safety decision-making based on the traditional unilateral fault protection strategy; Combining intelligent charging and discharging models to control battery operation in the optimal environment, safeguarding battery safety; Real time detection of insulation impedance reduces the risks caused by cable damage, battery leakage, etc. during the construction process. In short, multi-layer protection enables intelligent control and enhances system security.
Centralized control chain enhances system revenue
Traditional energy storage solutions are powerless against the barrel effect caused by the significant differences in battery characteristics and remaining capacity as the number of cycles increases. The centralized control chain energy storage solution fine manages the battery, minimizes the barrel effect, and reduces operation and maintenance costs.
Combining project cases and comparing centralized control chains with traditional energy storage solutions, the charging capacity has increased by 12% and the discharging capacity has increased by 7.1%; Increase charge and discharge cycles by more than 500 times during the battery life cycle; Reduce the cost of battery unpacking and reassembly by reducing the initial investment in the cascading utilization project. In short, the centralized control chain intelligent energy storage solution has taken a historic step towards reducing costs and increasing efficiency for energy storage systems.
GSSTES Product Series
Centralized control chain products of GSSTES are divided into three types: hierarchical utilization, medium voltage, and high voltage; The power ranges from 100kW to 500kW, and the DC input ranges from 4 to 12 channels. Different solutions are provided according to the customer's different application scenarios.
Rich and diverse modules are the cornerstone of Jingshi Technology's centralized control chain intelligent energy storage solution;
Multi dimensional intelligent energy storage management system (EMS) is the strongest brain of centralized control chain intelligent energy storage solutions;
The high reliability and high performance of optical storage integration are the guarantees for Jingshi Technology to establish itself in the international market.
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
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 the energy storage industry while doing its best.
