Following the "my country's Intelligent Manufacturing 2025" planning announcement, intelligent manufacturing has risen to national strategy. With the outbreak of the new energy vehicle market, the production of dynamic lithium-ion battery is gradually expanding, and the requirements for their performance are getting higher and higher. Typically, the automation level of lithium-ion battery is directly related to the quality of the battery, so the application of fully automated in the lithium-ion battery industry is increasingly concerned.

It is worth noting that many companies in China have been equipped with a fully automated module production line, and the output has been significantly improved and the production quality has also improved. At the same time, with the continuous intervention of intelligent equipment production, assembly and other links, MES systems is also widely used by major electrical cells and battery pack manufacturers. Pack is the key link of the upstream and downstream MES is the abbreviation of ManufactoryExecutiveesystem.

The power lithium-ion battery company wants to achieve intelligent manufacturing. It is necessary to realize real-time quality monitoring, production and quality data in real time by means of MES systems. Take back production process and realize paperless production management.

At present, the emergence of intelligent lithium-ion battery modules and PACK production lines has become a new idea for the transformation and upgrading of dynamic lithium-ion battery industries. In addition, the lithium-e-commerce robot application has passed the test water stage, and there is a more mature case in the industry. Pack customization is still the automation of the mainstream power lithium-ion battery generally contains the automatic / semi-automatic assembly line of the module and PACK, automated equipment integration, information acquisition and transmission (MES), unmanned workshop hardware and software management system.

Pack as a key step in production, design, and application of dynamic lithium-ion battery system, is the core link to connect upstream battery production and downstream vehicle, and the mutual intersection and collaboration of a large number of mature technologies, including the customization of battery management systems. Technology, thermal management technology, current control and detection technology, module assembly design technology, aluminum alloy dynamic lithium-ion battery oven casting technology, computer virtual development technology, etc. "Dynamic lithium-ion battery system PACK is very high, the performance parameters and indicator requirements of different vehicle manufacturers, the performance parameters and indicators of the dynamic lithium-ion battery system are different, need to match the specific model, require power lithium-ion battery The design, development and commissioning of system PACK must be combined with automotive vehicle design philosophy.

"Beijing Pleide New Energy Battery Technology Co., Ltd., Zhang Fu, said, Pack, Pack, to plan the indicators and parameters of the dynamic lithium-ion battery system in accordance with the vehicle design concept, and pass multiple performance testing and matching tests to be large Production and application.

Battery Pack Automation Sub-Charge Yang Yu Tell the reporter, the R & D of the dynamic lithium-ion battery system needs to be carried out according to the specific needs of the customs customers, after the project, method design, internal trial, sample test, joint test, national standard certification, product type, To the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology is reviewed, the Ministry of Industry and Information Technology announces the announcement of the announcements, from the project to achieve sales, usually from the equipment to delivery to 3-6 months. Since the requirements of various bus vendors in the current market are different, there is almost no modules and production processes that have two car companies. This also puts forward more requirements for the automation production line.

"Good automation production line except for the above hardware configuration and process requirements, you must focus on its compatibility and 'full line. Since the module is not fixed, the incoming battery, housing, PCB board, connecting piece, etc. may change.

The compatibility of the production line is especially important. Ma Zhile, deputy general manager of Jiangsu Tuxin Tian Robot Technology Co., Ltd.

pointed out. The "full line" mentioned by Ma Zhi Le refers to the average of the entire automatic line to work time beats of each workstation rather than the pipeline seen in the traditional sense. On the traditional production line, after completion of the last workstation, it is transferred to the next workstation, there is always a workstation waiting, so it is wasting the beat and efficiency.

It can be seen that the core difficulty of the power lithium-ion battery system Pack is customized market demand. High quality dynamic lithium-ion battery system Pack can customize R & D and design of dynamic lithium-ion battery BMS, thermal management, spatial size, structural strength, system interface, IP level and protection, etc. The organic bonding of the dynamic lithium ion battery pack, the interaction of various mature techniques, ensuring the safety and stability of the core energy storage device battery, and the effective lithium-ion battery system and different vendors of different vendors.

Matching and application. "Due to the high level of customization of PACK, it is difficult for PACK to be really standardized, but the powerful lithium-ion battery currently taken from the new energy bus is approaching the standardized route. "Yang Yu is said, early 2010, Prad wants to realize the standardized production line of PACK, but due to various factors, it is not largely promoted.

Automation production is a battery industry development trend Pack system is a battery-core service, to ensure consistency and high reliability. Key factors have two points, which use advanced intelligent equipment with high degree of automation, control from the production process, ensuring the consistency of the battery on each manufacturing node; its second increase Pack process level. According to Yang Yu, soon, Place will launch the Pack's module automation production line, and it is important to use the power lithium-ion battery of electric bus.

For the current Pack industry, it is generally to bear two important functions: transmission and detection. At present, major leadersmen generally have a fully automatic PACK assembly line, and of course, it also includes complex production processes, adapting to the requirements of the working environment, and some Pack Factory began research intelligent and informationization. Cracking the Pack Intelligence Puzzle From the moment of the current domestic Pack large factory, it began to get involved in intelligent lithium-ion battery module production lines and PACK production lines, which will intelligent as a new idea for the transformation and upgrading of dynamic lithium-ion battery industries.

"Implementing the intelligence of the pack line, can increase production efficiency, reduce production costs, improve data traceability, improve battery quality, and improve battery quality, and improve the quality of intelligent manufacturing to create a solid foundation for the company. Ma Zhi Le said. Yang Shu is in the words, "The automation of the entire new energy vehicle industry has not fully realized, and the automation of Pack is still continuously promoted.

Therefore, Pack intelligence is currently more discriminant, quality screening, etc., the overall intelligent goal has not reached ". In general, whether it is a soft bag battery, the hard shell battery is still our common 18650 cylindrical battery, the automated assembly process of the module starts from the battery.

This incoming material can be the packaging supplied by the original supplier, or the manufacturer has been uniformly organized after testing. The above can be manual operation, or it can be automatically added by the conveyor belt, and then crawl through the robot. At the same time, the cell read code (identity data information of a single battery) is collected, the cell polarity detection (without reverse direction), the battery sorting, and the resistance value (DCIR) detection, and will not Good to eliminate.

According to the requirements of the modules and process requirements, such as plasma cleaning-coating-electrical core stacking-battery case assembly - Extreme ear straps - module shell welding - module coding - screw-module detection - connection Welding-BMS system connection - module final detection - module feed. After the matching of the hardware and software, the integration of the MES system can directly create the above production lines to the quasi-unmanned production workshop. Towen New Day Intelligent Pack Production Line In Yang Fu, the current challenge of Pack is important as the following four aspects: first is safety, this is not only the problem facing Pack, but also the entire industry has been working hard.

The higher the energy density, the greater the challenges faced by safety performance, so the design and technical use of safety, this is a big challenge. Second, the reliability, the dynamic lithium-ion battery and the consumer battery are very different. The operation of the dynamic lithium-ion battery is relatively large.

How to achieve reliability on the current technology, this is a relatively large challenge for the entire Pack. Again is environmental adaptability, because new energy vehicles are used as transportation tools, most of the time is different in terms of open air, humidity, temperature, etc., which are different, which is also the topic to be solved by the power lithium-ion battery system, so that Safe operation safely in a variety of environments.

Finally, it is cost-effective, how to compete with traditional cars, and get the favor of consumers, we must solve from the technical level to the price level. "Realize PACK automation, improve safety, and also reduce people-factors related to products and production processes, the reliability has increased. From the configuration of the PACK to the configuration of the module, the specific parameters of the module, the data of the battery, the other feed information, etc.

, can quickly query and get information through the MES system, thereby effectively introducing production management level, effective Reduce production costs. "Ma Zhi Le said. And this, AGV car, power robot arm, roller line, boom, etc.

are simple and effective tools. The flexible line series is indeed inseparable from manual assistance, so semi-automatic Pack has become the mainstream configuration of each manufacturer. Of course, more and more customers will require the Pack and module MES system to better manage and quickly inquire, this related system integrator is another small challenge.
