Energy storage terminology and system lightning protection solutions

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...

Jinli experiential expansion in 2024
In October, our entire company participated in an outdoor team-building event themed “Glowing Brilliance, Striving Ahead.” This was not only an experience to strengthen our team cohesion, but also a symbol of our firm determination. Every employee’s efforts have driven our continuous breakthroughs in the field of low-voltage surge protection device, providing our clients with higher quality and more reliable products. On the first day of the activity, in the face of the outdoor drizzle, we flexibly moved indoors and opened a unique ice-breaking journey. Through well-designed group activities, each member quickly integrated into their own team, and the creative team style display not only narrowed the distance between each other, but also stimulated the vitality and creativity of the team. At that moment, we were partners and each other's strongest support. The next day, Jinli people embarked on a 26-kilometer trek. From the asphalt road to the rugged mountain road, from the stone path to the unknown shrouded in night, every step is a combination of persistence and courage. This is not only a physical contest, but also a spiritual baptism. In mutual support, we jointly conquered one mountain after another and moved forward step by step. In this process, we have seen the power of the team, the power of persistence, and the power of belief. Every persistence is a growth, and every challenge is a transcendence. Each team member has surpassed himself and achieved a double breakthrough of individual and team.Just as we overcame obstacles during the event, we apply the same tenacity in the design and production of our low-voltage surge protector, ensuring every product passes rigorous tests and environmental challenges. Through this event, we have realized that it is the collaboration and innovative spirit of our team that enables us to consistently deliver products our clients can trust. Known for their superior design, development, and manufacturing, our low-voltage SPD are committed to providing stable and safe protection in a constantly changing market. As the theme of this team-building event suggests, we are moving towards a brighter future with firm belief and solid actions. This dedication is what makes us a trusted partner for you.
