Ⅰ：Energy storage terms Stored energy：The process of storing energy through a medium or device and releasing it when needed. Through flexible charge and discharge control, it realizes the matching of production capacity and energy consumption in time and space. From the perspective of power system, energy storage can be divided into power generation side/power supply side, power grid side, and user side energy storage, of which power supply side and power grid side energy storage is also known as pre-table energy storage or large storage Pre-sheet energy storage：Energy storage that is directly connected to the power grid and has independent power and electricity meters; Otherwise, it is post-table energy storage, and user-side energy storage is also called post-table energy storage. User-side energy storage is divided into industrial and commercial energy storage and home energy storage. Domestic user-side energy storage mainly refers to the energy storage system applied in the majority of industrial and commercial customers, energy storage equipment can be simply understood as a large charging treasure. Charge when the electricity price is low, discharge when the electricity price is high for enterprise production, and earn the difference between peak and valley electricity prices, thereby reducing the cost of electricity for enterprises. Peak regulation：Transfer excess electricity from low-power areas to low-power areas. Because electricity cannot be stored on a large scale, it is generally necessary to use as much electricity as is generated. When the power generation of a region is constant, and the power here is not used up, it is necessary to transfer the excess power to the power shortage area through dispatch, or is the common pumped storage Frequency modulation：For example, the rated frequency stipulated in China is 50Hz, but the electrical appliances in production and life are complex and diverse, and the start-up of the machine will affect the power grid frequency, which requires frequency modulation to improve the power quality. PCS(Power Conversion System)：Realize the power conversion between the grid and the battery, and monitor and manage the exchange process. It can control the charging and discharging process of the battery, carry out AC/DC transformation, and directly supply AC load in the case of no power grid. PCS is composed of DC/AC bidirectional converter, control unit, etc BMS(Battery Management System)：It is mainly used for battery pack monitoring, calculation, communication and protection. It mainly consists of battery management chip, analog front end, embedded microprocessor, and embedded software EMS(Energy Management System)：It can realize real-time monitoring and intelligent management of all equipment in the system. Realize data collection, storage, processing, upload, operation control, operation strategy formulation, and so on, and carry out overall information-based monitoring and management Ⅱ：Lightning protectio...

On October 27, 2024, the 2024 annual meeting of Hunan Building Electrical Society was held in Yucheng Chaoyang Hotel, Changsha. The director of Hunan Building Electrical Society, the backbone members of major design institutes in the province, and more than 150 representatives of more than 30 electrical equipment manufacturers attended the annual meeting. Anhui Jinli Electric is a professional engaged in lightning SPD research and development, manufacturing, sales and provide overall lightning protection solutions of the technical service company, is also the only invited to participate in the lightning protection manufacturers, and in the venue with the visiting representatives had a good interaction. The exhibition exhibits include surge protector series, backup protector series, backup integrated surge protector series, signal surge protector series and lightning early warning system products, among which the lightning early warning system attracted the attention and consultation of many delegates at the venue. Surge protector is rapidly developing in the direction of intelligence and digitalization, from fault trip remote information, lightning count, to peak detection, waveform restoration, life warning and so on. As a professional lightning protection manufacturer, our company was also invited to share the development of lightning protection industry and the development of intelligence at the conference. After a day of communication and discussion, the annual meeting of Hunan Building Electrical Society achieved a complete success in the summary speech of the chairman of the society. Based on the enterprise development concept of "to protect users from lightning intrusion", the company is committed to the safety of electrical systems, focusing on the surge protection device technology of electrical systems, and independently developed lightning warning system and intelligent lightning protection system, transforming the passive protection of lightning to active defense, transforming the decentralized protection to the full intelligent protection of the system, and building a three-dimensional lightning protection and operation and maintenance management system. The company adheres to the "original as the guide" and is committed to promoting the continuous progress and development of the global lightning protection cause.

In October, the 14th staff Sports Meeting opened in the company's industrial park. At the opening ceremony, the athletes' phalanx entered in turn with neat steps and loud slogans. The games set a total of 12 major 13 sub-items, not only retained the popular items basketball, tug-of-war, but also increased the concentric drumming, slow cycling and other interesting items. On the field, the athletes are strong and hard working, and every game is full of tension and excitement. Tug-of-war, concentric drumming and other projects will bring the scene atmosphere to a climax, laughter, refueling sound one after another. After fierce competition, the champion and runner-up of each project were produced successively. At the award ceremony, the winning athletes held their MEDALS and their faces were filled with excitement and pride. At 18pm, the champion banquet was prepared in the Happiness Garden restaurant, and everyone drank wine and shared the joy. With the end of the championship banquet, the games came to a successful end. The event highlighted the employees’ energy, teamwork, and the company’s commitment to health and team-building. Throughout the competition, participants demonstrated perseverance and unity, showcasing the strong cohesion and vitality of the team. As a leading manufacturer of low-voltage surge protection device, Jinli continuously focuses on “Adhere to the original   manufacturing quality”, improving SPD performance to ensure the reliable operation of customer equipment. The spirit of dedication and excellence displayed in the event mirrors the company’s pursuit of perfection in product development and production. With renewed enthusiasm and confidence, the entire team is committed to driving the company’s growth and providing even better surge protector and services to our clients.
