With the continuous acceleration of my country’s new power automobile industry, the production of power batteries is also increasing year by year, and the field of power batteries receiving and re-applying has gradually become a new industry trend. When the capacity of the power battery decreases to less than 80% of the rated capacity, the power battery will no longer be suitable for electric vehicles. If it is too early to directly report the acceptance and takeover, the power battery that has been put into service is not only dismantled and extracted with priced metal data, but also the hierarchical application of the power battery is also a major acceptance and takeover application.
For the staging application of power batteries, Wang Jingzhong, Vice Chairman of the China Battery Industry Association, previously stated that for the remaining service batteries with sufficient residual power and stable quality assurance, they can be transformed into energy storage, low-speed vehicles and other fields through the staging application. Most of the leading companies for power battery stage application companies accepting and taking over the battery, such as Zhongtian Ding, Junzhou Haoling, and Jodemei. In addition to maintaining energy and environmental protection, the ladder application of power batteries can also be used to provide thin power batteries with cost, extending life cycle and economical.
Class application scenes are widespread
In my country, the power batteries that have been in service today are mostly phosphate steel batteries. In terms of battery functions, the performance of phosphate steel in staggered applications is more stable. Previously, Li Xie, a professor at Central South University, once said, “At present, nearly 90% of low-speed electric vehicles in my country are equipped with affordable price pallet acid batteries. If you can Sugar daddy baby uses the useful control of the capital, and when the price of the staggered power battery is close to the price of a staggered power battery, the advantages of the staggered power battery in component, driving mileage and charging and discharging time will be more obvious. ”
Compared with applications in the low-speed vehicle sector, service power battery has a wider application capacity in the energy storage. In March 2018, the seven national ministries and commissions jointly issued the “AboutIn the notice on organizing the launch of the test task of accepting and taking over the application of new power automobile power battery, it is clearly stated that the support of China Railway Tower Company and other enterprises combined with the test tasks in various regions will be carried out to carry out the construction of the demonstration project of the hierarchical application of power batteries.
The real application of staging batteries in energy storage
With the gradual perfection of my country’s energy storage terminal databases in recent years, the application of staging batteries in the Sugar daddy field has also become more and more refreshing. Today, my country has continuously launched the hierarchical application demonstration project operation in related fields such as large-scale renewable power network, assisted services, power distribution, and user side energy application. This includes kilowatt-level consumer energy storage products, 10 to 10 kW optical micronet, electric vehicle charging station energy storage systems, and data centers. href=”https://philippines-sugar.net/”>Sugar daddyreserved power supply, and megawatt-level large energy storage power stations, etc. According to relevant institutions, the market demand in my country’s energy storage field will become increasingly larger in the future, and energy storage may become the main application scenario for future power battery staging applications.
As for experts, communication base station is a very suitable for power battery ladder. Song Wei glanced at the sweet little girl on the opposite side, about 18 or 19 years old. The scene of application. With the increasing density of 4G and 5G network base stations, the demand for power batteries in ladder applications will gradually increase. In 2018, the China Iron Tower has completed the procurement of cubic acid batteries and a unified procurement of stairs to apply batteries. Gao Buwen, deputy general manager of China Iron Tower, once said that the total battery of China Iron Tower’s national base station exceeded 40GWh. It is clear that in 2019, China’s iron towers are expected to apply the stage application battery of about 5GWh, replace the acid battery with about 150,000 tons, and consume more than 50,000 tons of service power storage batteries. In 2018, my country’s service power batteries were also richer in energy storage on the side of industrial and commercial users. For example, China Heng Electric, Changcheng Power, Changen New Power and other companies are all here.The domain has a layout. In September 2018, the 1MW/7MWh tiered application industrial and commercial energy storage system project jointly constructed by Zhongheng Electric Power and Zhongheng Prere was launched in Rudong, Nantong, Jiangsu, and commercial operation was implemented. In June 2018, Changcheng Power Factory completed the 50kW/150kWh energized container assembly test and successfully shipped it. The 150kWh steel batteries in the project are all powered by electric vehicles, and the battery pack is directly used for ladder application without disassembly. In May 2018, the Changneng New Powered Steel Battery Cable Energy Station was delivered and used in the Innovation Industry Park in the National High-tech Zone of Wuhan.
In terms of micro-net energy storage, in August 2018, Guangzhou Electric Power Supply High Reliable Intelligent Low-Car Micro-net Project was launched in Nansha. It is clear that Nansha Micro-Net Project can achieve non-planned network conversion within 50 mm, intelligent switching of four network/orbital network operation methods, service power battery ladder application, and one week of operation. The project uses serviced electric vehicle power batteries, which realizes the ladder application of serviced batteries on micro-enabled Sugar daddy, improving the effectiveness of resource applications.
In terms of optical charging, in March 2018, the new charging stations put into use in the Liuhe Service District of Changshen Expressway in Nanjing, Jiangsu Province, all use service power battery ladders. As a part of the optical charging integrated power station, the project has implemented the application of photovoltaic-energy-energy charging mouse to the actual scene.
A series of application instructions, has the ladder battery returned in the energy storage field? “The application has been installed and I was stunned for a moment. A wide range of scenery. Peng Qingfeng, vice president of the New Power Automobile and director of the Joint Automobile Engineering Research Institute, has previously stated that “the application of power batteries will become a very long-term career in the ‘result market’ of new power automobiles.”
The problems facing the application of hierarchy
It is currently a major turning point for the large-scale service of power batteries in my country, and now we are in my country.ttps://philippines-sugar.net/”>Escort The purpose of the power battery hierarchical application tag is still in the stage of exploring growth, and there are still many disputes about the market prospects of hierarchical application at this stage. Huang Shilin, vice chairman and chief strategy officer of Ningde Times, once publicly stated, “Powerarchical application of hierarchical battery hierarchical application” It can be a life-threatening problem.”
Today, there are still some problems that have hindered the development of the treaded application of power batteries in my country.
1. The treaded application cost is relatively high. According to relevant experts, according to the technology and technology of our country, the actual cost of power battery treaded application does not have the advantage of high performance. At the same time, with the image of the “book-scented beauty” of power batteries. As one of the background characters, Ye Qiuguan has lost its life in the application of power batteries. In service, power batteries are transferred from receiving receiving to evaluating detection, with higher hidden costs. Some insiders believe that the above problems will become a confusion when choosing a new battery or a ladder when applying a battery.
2. Batteries lack divergence. Since my country first launched a demonstration and research project on the hierarchical application of power batteries in 2014, the problem of divergence in batteries has always been the main challenge facing the operation of hierarchical application projects. It is known that the discrepancy problems shown by the power battery in terms of capacity, internal resistance, voltage, etc. are closely related to the charging and discharging reaction mechanism of the battery itself. Previously, experts from the Chinese Academy of Electrical Sciences came to Xiaokang to express, “Even if there are thousands of selected service batteries, when building a tiered application energy storage system, it is still impossible to completely prevent the battery divergence from re-dispersing during system operation.”
3. Differences in technical routes. Some experts said, “Some people think that the energy storage battery is not acti TC:
