What are the features of smart lithium-ion energy storage system compared with ordinary lead-acid battery energy storage system? In terms of energy storage, people can easily think of batteries; outdoor power; mobile power; rechargeable batteries, etc., but the existing battery technology can hardly meet the requirements of grid-level energy storage. In fact, the energy storage market has huge potential. Lithium intelligent storage and control system is suitable for various solar street lights, solar building lighting, mobile communication, small power generation system, rooftop power station and other fields.
What are the characteristics of intelligent lithium storage system compared with ordinary lead-acid battery energy storage system?
Unlike ordinary energy storage systems, intelligent energy storage systems integrate communication technology, power electronics, sensing technology, high-density technology, high-efficiency heat dissipation technology, AI technology, cloud technology, and lithium battery technology. As a key component in the energy storage system, traditional lead-acid batteries are large and heavy, and the limited space in the server room and station site can no longer accommodate so many batteries. In energy storage systems, it has been the trend to replace lead-acid with smaller, lighter, higher energy density, longer life and better performance lithium batteries.

Better performance of the basic lithium function
Adopting the industry's highest density design, small volume, light weight, 150Ah capacity of only 3.6U, a cabinet can accommodate 600Ah, can replace old lead-acid batteries in situ, no additional cabinets, solving the telecom industry's long-standing headaches of difficult site access, high site rent, slow engineering progress.
Based on technologies such as sensing, communication, AI and cloud, it can detect and manage voltage, current, temperature and equalization functions in real time to achieve automatic protection and high-precision equalization for overvoltage/undervoltage, overcurrent and high/low temperature, which improves the efficiency of battery usage and reduces operation and maintenance costs, and also ensures 100% usage safety. Even in case of fire caused by extreme external reasons, the intelligent lithium battery can put out fire 100% by itself, meeting the demand for ultimate safety in communication rooms.
Station Synergy: Intelligent Voltage Boost, Intelligent Mixing, Intelligent Anti-theft
The voltage of the traditional energy storage system itself will gradually drop as the battery discharges, and even a voltage dip will occur, which poses a greater challenge to the stability of 5G power supply.
Intelligent energy storage system by linkage and synergy with 5G power supply, 100Ah intelligent lithium discharge capacity is equivalent to 200Ah ordinary lithium or lead-acid batteries, support 57V constant voltage output, no need to use thick cables, 100% release of power, can enhance the site power supply distance and reduce battery investment.
For the old and new batteries or different kinds of batteries mixed together will produce bias current problem, intelligent energy storage system can realize intelligent cooperation between different battery packs and power supply, intelligent regulation of bias current and loop current between battery packs to limit the current sharing management, to realize the output power without loss of intelligent parallel. Taking a typical 8kW power consumption 1h backup scenario as an example, the industry's ordinary energy storage system requires four groups of 100Ah lead-acid or lithium batteries, while the intelligent energy storage system only requires two groups of 100Ah intelligent lithium batteries, saving two groups of batteries and a cabinet, thus reducing the area and reducing the site rent.
The intelligent energy storage system can also automatically adapt to the voltage of different battery packs, free of additive combiners and lead-acid batteries, new and old lithium intelligent mix and match, maximizing the use of existing batteries, not only to protect assets, but also to reduce the 5G evolution step-by-step investment. Meanwhile, for the problem of frequent battery theft, the intelligent energy storage system can realize online intelligent software lock anti-theft and offline intelligent displacement lock anti-theft and GPS location tracking through intelligent synergy with power supply and network management to minimize theft loss.
Inter-station/station network synergy: intelligent peak shaving, intelligent peak staggering, and fine management of the whole network
During peak load, intelligent energy storage system participates in load power supply to achieve "intelligent peak shaving", thus enabling "no utility change" to 5G evolution, reducing investment and accelerating 5G deployment. With intelligent network management and grid intelligence collaboration and the high cycle performance of smart lithium battery, it can also be charged during low tariff hours and discharged during high tariff hours through "intelligent peak-shaving", thus saving electricity and activating the value of the battery.
For the future, the energy storage system equipped with intelligent lithium battery and network management can work together intelligently to achieve a network-wide energy storage system that is visible, manageable and controllable; through big data and AI analysis and prediction, it can realize forward-looking operation and complementary battery resources between stations, thus reducing operation and maintenance costs and wasting resources.

②The cost of new energy generation will be further reduced, and its penetration rate in the power system will continue to increase, and the cumulative installed capacity of lithium storage is expected to reach 9.23GW/27.69GWh in 2024.
③In 2020, China will enter the peak of 5G construction, and the installed capacity of lithium storage is expected to reach 12.48GW/43.68GWh in 2025. will reach 37.7 billion, about 20 times compared with the current market size.
Conclusion: The global new energy and smart grid industries are proliferating, providing a huge market space for the energy storage battery industry. Li-ion battery industry in China already has a perfect industrial chain, later with the progress of technology, Li-ion battery is certainly only a transitional product, there will be better ways of energy storage.
