Analyze the classification and technical characteristics of the power lithium battery detection system. Most lithium batteries are used in groups. Therefore, it is of great significance to test and evaluate the performance of the battery pack and to propose optimization and improvement suggestions. With the continuous expansion of the application field of lithium batteries and the advancement of industry technology, the lithium battery detection system is developing in the direction of energy saving, high efficiency, high performance, high precision and intelligence. The technical requirements of lithium battery production equipment vary. Competitive landscape of the lithium battery testing system industry 1. Foreign-funded enterprises have a long time of technological development and high brand effect. Lithium batteries are a newly developed green energy source in the last century, and their research and development are highly valued by all countries. The development of foreign lithium battery testing systems started earlier and the technology is relatively mature. Among the global lithium battery testing system manufacturers, there are well-known companies with large scale and high market share, such as Bitrode in the United States, Digatron in Germany, and AV listed on NASDAQ. Foreign companies have market-first advantages, high brand effects, and occupy a certain market share in high-end lithium battery testing systems. 2. The rapid technological development of domestic enterprises and the obvious advantages of local services. The rapid development of domestic lithium battery applications and the rapid growth of lithium battery market demand have promoted my country's lithium battery testing system manufacturers to increase their own development efforts. At present, domestic companies have developed lithium battery detection systems in different application fields. The technology is mature, and some product parameters have reached the international leading level. With the rapid development of domestic enterprises' technological level, some products of leading enterprises have been applied to the supply chain of downstream enterprises, and they have strict requirements on suppliers. Classification of lithium battery detection systems (1) Different objects: Lithium battery detection systems can be divided into core detection systems, module detection systems, lithium battery detection systems, etc.; (2) Different application areas: lithium battery detection systems can be divided into mobile phone batteries Testing system, laptop battery testing system, power tool battery testing system, electric bicycle battery testing system, electric car battery testing system, etc. (3) Battery assembly and test process: Lithium battery test system includes battery core classification and test system, charging and discharging test system, protection board test system, wiring harness test system, BMS test system, module EOL test system, battery pack EOL test system , Working condition simulation test system, etc. Industry technical characteristics of lithium battery detection system Lithium battery gold system technology is complex, involving measurement and control technology, energy conversion technology, power conversion technology, system integration and manufacturing process technology, etc. The development and integration capabilities of corresponding technologies determine the quality of the test system. The target requirements of lithium batteries are different, and the skill requirements of the detection system are also different. Lithium battery detection system skills are relatively cumbersome, such as touch measurement and control skills, energy change skills, power change skills, system integration and process technology. The technical level of the lithium battery detection system is closely related to the battery type, the index requirements of the lithium battery and the application field. The current main products such as 18650 batteries, battery soft packs, such as square lithium-ion batteries, battery charge and discharge test and equipment have been relatively mature, and the energy feedback type battery charge and discharge test system related to new energy vehicles, battery state simulation test system, such as high Power battery charging and discharging detection system detection technology is developed and promoted. With the development of lithium battery commercial power sources, the expansion of the scope of application, and the requirements of downstream enterprises to reduce production costs, the requirements for energy saving, detection power supply and lithium battery detection system power supply have also increased. Lithium battery production equipment, traditional energy-consuming high-power charging and discharging lithium battery detection systems need to consume a lot of electric energy during the charging and discharging process, but selective skills, such as energy feedback techniques, can greatly reduce energy consumption and achieve significant energy-saving effects. The lithium battery testing system industry has the characteristics of complex downstream technology, multiple production links, and long processes. As the improvement of the automation degree of the downstream lithium battery production equipment manufacturing industry and the intelligent manufacturing system, the establishment of the data collection, analysis and prediction, control, feedback, and tracking of the various nodes of the production process of the enterprise lithium battery detection system, human-computer intelligent interaction, high integration, There are more urgent requirements for intelligent production and intelligence. With the development of commercial power of lithium batteries, the expansion of the scope of application and the requirements of downstream enterprises to reduce production costs, the quality inspection system of lithium batteries can only be determined by the requirements of energy saving, inspection power and power lithium battery inspection systems and corresponding development and integration capabilities. . With the continuous expansion of the application range of lithium batteries and the improvement of professional skills, the lithium battery detection system is developing in the direction of energy saving, high power, high performance, high precision and intelligence.
