Analysis on the product specification and size of electric vehicle power battery

Electric Vehicle Power Lithium-ion Battery Product Specifications and Dimensions Recently, the Ministry of Industry and Information Technology announced the national standards recommended by the Electric Vehicle Standards Committee, the 'Electric Vehicle Power Lithium-ion Battery Product Standard' and the 'Automotive Power Lithium-ion Battery Specification'. Draft for comments). In this opinion draft, automotive power lithium-ion batteries are divided into three categories: cylindrical, square and flexible packaging. Industry insiders pointed out that it is inevitable that power lithium-ion battery product standards are consistent with standardization, which will help further promote the domestic power lithium-ion battery market concentration and reduce the pressure on power lithium-ion battery manufacturing funds and vehicle companies. Now including battery companies, system integration companies, automobile companies and battery recycling companies are actively promoting the consistency of the standard scale of power lithium-ion batteries. However, the investigation found that in the process of promoting the unification of power lithium-ion battery standards, vehicle companies and power lithium-ion battery companies cannot fully achieve the same pace, and there is even a certain conflict of interest. The standard scale of the power lithium-ion battery is consistent with the load range. Improved automotive companies' awareness of standard battery standards. The development of new energy vehicles and power lithium-ion batteries is obviously restricted by the diversity of power lithium-ion battery types and different standard standards. With the accelerated development of the new energy car business, whether it is a power lithium-ion battery company, the need for standardization of power lithium-ion battery standards is becoming more and more urgent. The person in charge of the Automotive Standardization Technical Committee pointed out that there are only a few electrochemical systems for industrialized batteries, but there is no unified standard for specific products, which brings many problems. On the one hand, the increase in Ru0026D costs of battery manufacturing companies is not conducive to the large-scale planning and processing, market investment and material technology innovation of battery manufacturing companies. On the other hand, the new Ru0026D costs of system integration companies and vehicle companies have made it impossible to complete the rapid selection of single batteries, and it is difficult to accumulate skills, which weakens the competitiveness of vehicle products. At the same time, the inconsistency of battery standards has also increased the difficulty and complexity of battery recycling. From an objective point of view, the confusion of the types of domestic power lithium-ion batteries is caused to a certain extent by the many requirements of original equipment manufacturers. It is the recognition of this problem that some automakers have begun to explore standard battery standards in internal standard battery standards, and United Battery Corporation is actively exploring battery standards. We have standardized the battery scale internally, formulated rules for several battery suppliers, and selected the battery that is more suitable for them. Chery New Energy Automobile Co., Ltd. New Energy Automobile Dean NiShaoYong pointed out that the OEM manufacturer, then the battery factory, and the packaging factory can integrate the entire building skills and consistent standards to complete the small batch processing of power lithium-ion battery types with fewer varieties, Lower purchase funds for mass processing. In addition to Chery, some domestic and foreign automobile companies have also begun to pay attention to the standards of power lithium-ion batteries, and they have begun to strictly regulate the scale of batteries, which may gradually reduce the installation planning of battery models. For example, all future electric vehicles of the group will adopt a single lithium battery design. By simplifying the battery design, battery costs will be reduced by 66%. BYD's commercial vehicle battery modules have been basically standardized and can be completed through different assembly structures to meet the needs of different models; Nanjing King Long has proposed the same standard for battery suppliers, which can be interchanged internally.
