The reporter learned from the Ministry of Industry and Information Technology yesterday that the Ministry of Industry and Information Technology has completed the application of the power battery code of 34 ladder-use enterprises to achieve the traceability information management of the enterprises using the ladder. The Ministry of Industry and Information Technology has proposed that the utilization of new energy vehicle power battery ladders is in its infancy, with great development potential and broad market prospects.

Why do batteries need to be used in cascades? After the new energy vehicle power battery is decommissioned, it can maximize the utilization of battery residual energy resources through the use of the ladder. Generally, when the capacity of a new energy vehicle power battery is attenuated to less than 80%, it will not be able to fully satisfy the vehicle power demand, but it can be used in other fields.

The use of ladders is also an urgent need for energy conservation and emission reduction. According to the prediction of China Automotive Technology and Research Center, combined with factors such as automobile scrap years and power battery life, from 2018 to 2020, the total number of scrapped power batteries in the country will reach 120,000-200,000 tons; by 2025, the annual waste of power batteries will reach 35 10,000 tons of scale.

Waste power batteries not only have the possibility of causing heavy metal pollution, but also have strong corrosiveness and toxicity of electrolytes, which are prone to produce toxic chemical gases and endanger human health.

In this regard, the Ministry of Industry and Information Technology has actively carried out pilot projects for the recycling of new energy vehicles' power batteries, and promoted the use of elevators in the areas of power generation and energy storage, and explored new business models in enterprises such as automobile manufacturing, battery production and comprehensive utilization.

State Grid built a 100kWh ladder in Beijing Daxing to use the lithium manganese oxide battery energy storage system demonstration, and built a 1MWh ladder in Zhangbei to use the lithium iron phosphate battery energy storage system demonstration to effectively verify the feasibility of the use of the energy storage field. At the same time, the decommissioning battery sorting evaluation technology platform was established, the battery matching technical specifications were formulated, and an efficient and reliable battery management system was developed.

Beijing Artisan has developed a cascade of optical energy storage systems and is building a power battery pack (group) evaluation system based on big data. Beijing Pride and BAIC have cooperated in the implementation of energy storage power station projects and containerized energy storage projects, with a cumulative utilization of about 75MWh.

China Tower Company has used 12,500 base stations in 31 provinces across the country to use battery-backed power applications. The use of batteries for the use of ladders is about 1.5GWh. The current operation is good, which fully verifies the feasibility of safety and technical economy. At the same time, China Railway Tower took the lead in breaking through the key technologies of batch utilization such as battery grouping and capacity evaluation.

Shenzhen BYD, Guoxuan Hi-Tech and other enterprises use decommissioned power batteries to produce battery products for the use of electricity in the field of backup. Wuxi GEM and SF Company explored the use of batteries for urban logistics vehicles, and Zhongtianhong Lithium promoted the use of batteries in sanitation and sightseeing vehicles through the “sale and sale” model.

The National Automobile Standardization Technical Committee has organized and implemented national standards for the development of power battery ladder utilization standards and residual energy testing. China Iron Tower Corporation is taking the lead in developing relevant industry standards for the use of ladders in the communications field.

The Ministry of Industry and Information Technology clearly stated that the utilization of new energy vehicle power battery ladders is in its infancy, with great development potential and broad market prospects. The problem is that key technical bottlenecks such as battery remaining life and consistency assessment have yet to be broken, and management mechanisms and business models need to be further explored and improved.
