Since 2024, Sugar daddy has accelerated the entry into the technical competition.
On the one hand, the single pure price has made more and more people in the industry feel worried about the sustainable development of energy production. On the other hand, the development of energy-energy technology has not reached a time when the format will be set. The pressure of technical competition comes from both the inner coil and the real needs of the industry.
Zeng Yuqun, chairman of Ningde Times, said that although the energy equipment market is small in scale, its repetition is far beyond the transportation market. Zeng Yuqun compared a gigaW battery energy storage system to a Boeing 787 aircraft with a larger number of parts than 7 million to 9 million.
Yangguang Power Chairman Cao Renqin pointed out in April this year that the average application rate of energy-efficient equipment is relatively low, and business forms such as power inventory and assistive services are not yet perfect. In addition, there are tens of thousands of energy-energy enterprises in China today, and the gross profit margin of major sector products is relatively low. The company lacks continuous resources and fees to continue investment and research and development. Ping An still has problems with concerns.
Yingxin Energy Chairman Liu Jincheng said that a large-scale industry that sells its capital will not continue. It must leave space for every company in the industry with innovative and quality guaranteed talents, so that this industry can continue to develop.
The industry leader’s “insight” of current energy production has realized the “deformity” of current industry. Then, if the energy industry wants to get ahead as soon as possible, there will be no shortage of competition in the technical field.
At present, the competition of energy storage technology, on the one hand, has achieved multiple dimensions such as safety, cost reduction, and function of steel batteries; on the other hand, liquid flow batteries and ion batteries accelerate the research and development and application in the energy storage field, making energy storage technology appear as a “flowering”.
Based on the new product situation of many exhibitions this year, Gaogong Energy has sorted out some key energy storage technologies that have emerged this year. Among them, the series type, network, AC and DC unit, full liquid cooling, large capacity core, chip cutting technology, high temperature batteries, silicon carbide, liquid flow batteries, calender batteries, etc. may be the purpose of the “ten-year” energy storage technology evolution or possible differential development standards in 2024.
The annual technology of this article is based on the observations of various exhibitions.
Serialized
Serialized energy storage system is composed of multiple smaller capacity energy storage units, each unit has independent control and governance effects. This evacuation-style architecture gives the string energy storage a high degree of flexibility and expansion.
At this year’s exhibition, the string PCS has almost become the “standard” of new products of 5MWh and above. People from many industries have shown that with the continuous changes in core and system capacity, the series PCS can greatly improve the safety of energy.
In addition to mainstream energy storage system manufacturers, Yang OptoelectronicsIn addition to digital power, many PCS manufacturers follow this route.
Shenghong Energy has been adhering to and improving module multi-branch technology for 12 years, realizing precise clustering management of batteries, effectively eliminating and distributing problems and circular flow. In the field of major, it developed a module PCS for major projects in 2024, and was also ongoing at the September exhibition.
In the series energy storage field, Hekan Electric brought a wind-cooled 250kW series PCS and a 1~5MW series transformer booster at the SNEC exhibition in September. The series of products are fully certified and have been shipped in batches.
Similarly, at the SNEC exhibition in September, Shangneng Electric exhibited a 5MW series energy-easing transformer booster. It is clear that the product adopts a highly integrated design, and the single machine has IP66 protection + C5 anti-corrosion performance, which can achieve battery cluster management and flexible installation and expansion; the IP68 fast plug terminal design doubles the simplified installation and maintenance tasks.
It is worth mentioning that the first batch of 22-stage series energy-easing and voltage-reducing machine shipments supplied by Shangneng Electric for the american market. It is worth mentioning that Songsheng Innovation has also produced a number of new series energy storage products – the 235kW three-phase high-pressure energy storage variable SSE-HH235K-P3CN, three-phase high-pressure 60kW hybrid inverter SSE-HH60K-P3EU, and the North American 8kW~15kW storage product SSE-HL8K~15K-P2US Measurement SNEC Exhibition.
Instrumental Network
Instrumental Network can hide from a single trick document in 2022, and the industry has gradually realized the importance of the network. As new power transmission continues to rise, the demand for energy storage networks is becoming increasingly obvious, and the response to energy storage technology developed by the network is still continuing.
This urgent need is important from the current demand in the western region and some weak network regions. But in the future, with the realization of the “dual carbon” goal, the large-scale development of new forces is no longer divided into regions, and supporting the stable operation of new forces and power systems is a global demand. The advantages of network power generation are obvious in improving new power generation capabilities, transport channel transmission capabilities, improving power supply reliability, load-bearing and load-bearing power supply capabilities, adding power black startup resources, and power black startup effectiveness. The global network power generation needs will also be very clear.
As the demand for networks gradually emerges, there are two important types of energy storage systems. One is the network of low-pressure energy storage systems, and the other is the network of high-pressure energy storage systems.
In the high-pressure network field, the current important ones are Nanrui Insurance, Yishite, Xinfengguang, and ZhiA high-pressure direct-envelope energy storage system is released for optical power, etc.
In low-pressure network, except for Nanrui’s warranty, Sunlight Power, Digital Power, and Escort Manila have demonstrated their network capabilities in the project Pinay escort. Among them, the PCS ring also focuses on the network energy supply, and Shenghong Co., Ltd., Shangneng Electric, Soying Electric, and optical power are distributed in network PCS.
AC-DC-based one-piece
Clearly, AC-based one-piece means saving PCS, LC and other equipment to cover the land and maintain space, covering 29% of the area, and at 100 megawatts Pinay escortEnergy station is only 2,000 square meters. “The cold wind is biting, and the snow in the community has not melted. One body” can be further eliminated from the four major events on-site PCS installation, DC connection, communication test, and charging and discharging test.
The traditional DC cable is exposed and has great dangers. The AC-DC system is not out of the closet, and the standardized short-wire cable is built into the full liquid-cooled heat-dissipating “air conditioning room” to prevent all kinds of safety hazards. In addition, it is equipped with large current AI arc technology to turn off the arc level in seconds to ensure the safety of the entire cabinet.
In October 2023, the Sun Optical Power Supply Industry took the lead in releasing the AC-DC-based, fully liquid-cooled PowerTian 2.0. According to the executives of Yang Optical Power Supply, the “AC-DC-One-Physical” design has a variety of advantages, (1) Simplified live installation and adjustment to improve engineering safety and effectiveness; (2) High energy density; (3) Strong safety; (4) Long circulation life and high maintenance; (5) Realize network technology and Internet lovers’ love; (6) Automatic adjustment of liquid cooling forms, and low operating energy consumption.
Incomplete statistics, Sunlight Power, Far Scenic Power, Coronavirus Electronics, Lishen Battery, Ronghe Yuanqi and others have all released AC and DC energy storage systems.
In the first half of this year, the “Huain Longteng Special Steel 20MW/40MWh User Side Energy Project” invested by China Huaneng Group and constructed by Eleven Technology EPC, has a full capacity and network power generation, and a total of 8 sets of 2.5MW/5MWh yang optical power supply PowerTitan 2.0 liquid-cooled energy storage systems were invested by China Huaneng Group and constructed by Eleven Technology EPC. This is the first energy-energy protagonist in China with an “AC-DC-One” design, but she is regarded as a perfect stone for the station in all aspects.//philippines-sugar.net/”>Sugar baby, the system’s effectiveness is higher than traditional energy storage2Sugar daddy%-3%, marking the accelerating era of “AC storage”.
In April this year, Far-Sight Energy released the world’s first “Jing TC:
