Always takes technological innovation as the engine, independent and controllable as the foundation, and green and low-carbon as the mission.

Jiangxi for science and Technology Co., Ltd. has been deeply engaged in the field of new energy for many years, always taking technological innovation as the engine, independent control as the foundation, green and low-carbon as the mission, and is committed to becoming the world's leading provider of new energy system solutions. In the field of energy storage system, the company adheres to the development path of full stack self-research of core technology, and has fully mastered the complete technology chain including battery material system development, structural optimization design, thermal management and electrical safety design, battery management system (BMS) algorithm, energy management system (EMS) strategy and system integration. Relying on the continuously strengthened research and development investment and industrialization capability, the company has successfully realized independent research and development and large-scale mass production of lithium iron phosphate energy storage battery cells, modular energy storage cabinets and standardized battery cluster components. The localization rate of core components exceeds 95%, and the key process equipment and software platform are 100 independently controllable, thus fundamentally getting rid of the dependence on external technical routes. The product has high energy density, excellent consistency and excellent low temperature performance, and maintains stable charge and discharge efficiency in the wide temperature range of -20 ℃ to 60 ℃. The measured cycle life is more than 6000 times, and the capacity retention rate is still higher than 80%, which is significantly better than the industry average. It is particularly worth mentioning that the company has innovated and constructed a three-level active safety protection system covering core level, module level and system level. It integrates multiple technical means such as early multi-dimensional signal identification and early warning of thermal runaway, millisecond graded fuse protection, intelligent temperature control linkage, automatic inerting suppression and cooperative response of fire fighting system, etc. to improve the intrinsic safety level from the design source and ensure the high reliability and high availability of long-term operation of the system. With excellent performance and flexible and adjustable power and capacity allocation capabilities, this series of energy storage products have been widely used in various typical scenarios such as household energy storage, peak-valley arbitrage for industrial and commercial users, frequency adjustment and inertia support for microgrids, frequency modulation for new energy power stations, emergency backup power supplies, etc., providing solid and reliable infrastructure support for flexible adjustment, safe and stable operation and intelligent upgrading of new power systems. In view of the dual challenges of the increasing shortage of global water resources and the transformation of agricultural modernization, the company independently developed intelligent photovoltaic water pump system, creating a new paradigm of green water lifting with zero energy consumption, zero emission and zero noise. The system adopts a pure solar direct drive architecture, does not need to be connected to the mains, and does not rely on traditional energy sources such as diesel generators. It truly realizes zero fuel consumption, zero carbon emissions and silent operation throughout the life cycle, with outstanding ecological friendliness and good Economic applicability. The system deeply integrates MPPT intelligent maximum power point tracking algorithm, water level adaptive dynamic adjustment control strategy, dry burning automatic identification and shutdown protection, overload overheating multi-level protection and other core technologies, stable and reliable operation, convenient and efficient installation, simple and intuitive operation and maintenance, investment recovery cycle is generally shorter than three years. At present, the system has successfully implemented dozens of demonstration projects in typical areas such as the arid and semi-arid areas of central and western my country, the main rice-producing countries in Southeast Asia, and the lack of electricity and water in sub-Saharan Africa. The cumulative irrigation area exceeds 50000 mu, benefiting more than farmers. 30000 households. It not only effectively alleviates the shortage of local agricultural irrigation water and the difficulty of residents' daily water intake, but also significantly improves the guarantee capacity of farmland water conservancy and agricultural production efficiency, creates considerable economic benefits, and simultaneously brings significant water-saving and emission reduction effects and far-reaching social livelihood value. In terms of photovoltaic power station construction and service, the company holds the national power engineering construction general contracting qualification, and has the ability of one-stop EPC project general contracting covering the whole life cycle of the project. The business scope covers preliminary resource assessment and feasibility study, customized system scheme design, efficient equipment selection and system integration, professional construction and installation, fine grid connection commissioning, and intelligent remote operation and maintenance management services for up to 25 years. Relying on the experienced engineering and technical team, the whole process quality control system and the digital energy management platform independently developed by the company, the company can provide high-yield, low-risk and sustainable photovoltaic power station solutions for customers of different sizes, different regions and different application scenarios. The platform integrates real-time data monitoring, intelligent fault diagnosis, in-depth analysis of energy efficiency, predictive maintenance suggestions and other functions. It supports multi-site centralized management and remote control of mobile terminals, helps customers realize visualization of asset status, digitalization of operation management and refinement of decision analysis, and comprehensively guarantees efficient coordination, intrinsic safety and stable gain of all links of the project from planning, construction to long-term operation. Facing the future, Jiangxi for science and technology co., ltd. will continue to implement the business philosophy of "innovation-driven development, quality-building brand, green leading the future", focusing on the research and development of new energy storage material system, optical storage collaborative intelligent scheduling control, AI-driven intelligent operation and maintenance platform upgrade, low-carbon energy system integration and other cutting-edge directions, continue to increase research and development investment, and accelerate the pace of technology iteration and product upgrade. The company is determined to become a reliable provider of new energy solutions in the world. With better product performance, more professional technical services and more pragmatic cooperation mode, the company will join hands with partners at home and abroad to jointly promote the green and low-carbon transformation of energy structure, actively help the national "double carbon" strategic goal to achieve high-quality landing, in order to build a clean, low-carbon, safe and efficient modern energy system, For the beautiful vision of sustainable development of mankind, contribute solid and warm for strength.
