Portable Energy Storage Power With the continuous popularization and upgrading of smart devices, people's demand for mobile power is also increasing. Faced with the increasingly rich and complex functions of intelligent tools, more power support is needed. At the same time, with the continuous development of emerging fields such as wearable devices and smart homes, portable power station has become an indispensable part of people's home office, travel, camping and adventure. Now, we have some new style portable power station. It is also known as portable energy storage power supply which is a device that uses high energy density lithium-ion battery packs as a means of energy storage to provide power supply for users when they cannot access electricity. Outdoor power supplies can provide power support for almost all electrical equipment. It has a larger capacity, support 220V AC output, support USB fast charge output, support vehicle cigarette lighter output, DC output, lighting torches, and even wireless chargers and other functions, as far as possible to provide users with more ways of power protection. More Advantages : The inverter uses high-frequency resonance technology, and the volume of the whole machine is reduced by 40%. 95% high efficiency conversion and cooling completely silent, zero noise. Alloy enclosure closed design, dustproof and waterproof IP52 professional grade. 6 Series alloy housing, 70% stronger than plastic. 3-stage charge management, multi-level battery management, the safety of the whole machine is improved by 100%.

In mid-September, news came from the Shaoxing Science and Technology Bureau: The 2020 Shaoxing Science and Technology Plan Special Project "Lithium-ion battery power system for 5G micro-stations supporting online expansion" (hereinafter referred to as "5G micro-site lithium battery") recently officially passed the review of the project mission statement, which marked the successful establishment of the project, a breakthrough in the online expansion strategy and a sound reflection of various mechanisms of intelligent BMS and battery monitoring systems. According to data, my country's 5G information transmission technology is at the forefront of the world and is China's advanced technology business card. According to the 5G construction plan of the three major operators, my country will enter a large-scale construction period of 5G base stations from 2020, and there will also be a huge demand for backup power. Since the company`s lithium-ion battery products were put into production in 2010, it has been mainly engaged in the production of lithium iron phosphate batteries for communication base stations. It has formed a 48V (10Ah-100 Ah) series of integrated communication back-up lithium-ion batteries, which have been successfully commercialized in China Foreign telecommunications operators and power equipment manufacturers have been recognized by customers. Based on the market prospects of the backup power supply for 5G base stations and the company's industry accumulation in related fields, it is urgent to develop a 5G efficient and safe backup power supply system that supports online expansion. With the changes in people`s lifestyles, fields such as the Internet of Things, smart transportation, and smart cities all have urgent needs for 5G communication technology, and the successful implementation of these fields must be based on the uninterrupted 5G information transmission. It means that the "5G micro-site lithium battery" project needs to break through the bottleneck problem of "hot plug" before it can provide a set of safe, reliable and efficient smart solutions in related fields. At present, the "5G micro-site lithium battery" project team is working in an orderly manner, and will continue to make efforts in all aspects of core technology, process, component design and risk control. After the project is successfully implemented, it will not only provide information security for 5G base stations. Stable transmission is of great significance, and it will also bring huge economic benefits to the company, inject strong technological momentum into the innovation and development of Wolong Dengta, and help the company's green and intelligent high-quality development.

In July this year, Wolong lithium battery technical team developed the model WL48-40FT09-5G lithium battery product, which successfully passed the IP65 waterproof test certified by the TUV testing agency and obtained the qualification certificate. A new customer in Thailand also expressed their satisfaction with Wolong Dengta's lithium battery products, and may achieve long-term friendly cooperation in the future. With the development of the 5G era, the demand for 5G batteries at home and abroad is also showing an upward trend. While market competition is fierce, strict control of the quality of battery products will be more conducive to our products in the domestic and foreign markets. Because the working environment of 5G batteries needs to be exposed to the outdoors for a long time, the requirements for the quality and sealing of the battery case are extremely strict, and a slight carelessness in the process details will reduce the battery life and even dangerous situations. On the other hand, the sheet metal case for 5G batteries has successfully achieved waterproof performance, which is also an important breakthrough in lighthouse lithium battery technology. Carrying out multiple certifications on products is the responsibility of Wolong people for the products, for the customers, and for the future development of the company. We firmly believe that only by continuous innovation and focus on research and development, Wolong products will advance with the times and be at the forefront of the times.
